Effects of stratification and mixing on spatiotemporal dynamics and functional potential of microbial community in a subtropical large-deep reservoir driven by nutrients and ecological niche

Seasonal thermal stratification is a common environmental phenomenon in reservoir water bodies and an important research topic for deep water reservoirs. A thermally stratified reservoir is an ideal system for investigating the interaction between factors affecting the environment and microorganism communities under spatial–temporal variation. However, few studies have focused on the effects of water stratification and mixing periods in microbial communities and nitrogen conversion. Therefore, using metagenomic sequencing and quantitative polymerase chain reaction, we investigated the microbial diversity and function in the Xin'anjiang Reservoir during water stratification and mixing period. Principal component analysis indicated that the bacterial communities were mostly affected by water stratification, mainly at 10-m depths, whereas the archaea community was influenced by the entire water profile. The predominant archaeal phyla changed from Candidatus_Woesearchaeota and Euryarchaeota to Thaumarchaeota with the increasing water depth during water stratification. The stratified variations of the dominant archaeal phyla strongly reflected the seasonal changes and vertical gradient in water temperature, dissolved oxygen, and pH. Linear regression analysis indicated that variations in microbial composition altered the overall functional attributes of the communities, especially in the archaeal community. Regarding nitrogen metabolism across the whole reservoir, the number of nitrification and denitrification genes dropped in the same direction as the river flow in spring and summer, while the opposite trend was observed in autumn and winter. The functional genes of the water profiles in the transitional and lacustrine zones varied considerably except in winter. Additionally, the copies of nitrification-related genes were more during the stratification stage than during the mixing stage, whereas copies of denitrification-related genes showed the opposite trend. Overall, this study provides unique insights regarding the effects of seasonal stratification on the distribution and function of microorganisms in large-deep reservoirs, which should be considered when establishing guidelines for reservoirs management.

Diffusion mechanisms of convective instability in liquid and gas mixtures

AbstractA review of publications on stability of mechanical equilibrium of multicomponent mixtures in gases and liquids under non‐isothermal and isothermal conditions is given. Studies where diffusion in binary and multicomponent mixtures led to the occurrence of instability of mechanical equilibrium of the system have been analyzed. The main attention is paid to the description of approaches predicting the areas where there are increasing convective disturbances, as well as the determination of the spectrum of thermophysical parameters where the contribution of convection to heat and mass transfer is negligible. At the same time, the problems determining the role of diffusion, thermodiffusion, and double diffusion mechanisms in the separation of mixture components at the boundary of convective instability were given priority in the description. The results of investigations related to the study of the evolution of flows arising due to instability at the initial stage of mixing were also discussed.

Investigating PCM encapsulated NaOH additive for set-on-demand in 3D concrete printing

This study investigates the print head activation of an encapsulated additive to attain on-demand setting in 3D concrete printing for buildability enhancement. Sodium hydroxide (NaOH) is considered as a set accelerating additive, and it is encapsulated using a phase change material (PCM). The encapsulated NaOH is added during the initial mixing stage and the mix is heated at the print head to release the NaOH, which subsequently reacts with cementitious materials to attain the on-demand setting of the printed layer. The dosage of NaOH was varied from 0 to 5 wt% of the cement to determine the optimum dosage for buildability enhancement. The results showed that the static yield strength of the printable concrete after the print head activation increased with the NaOH dosage, however, this has resulted in reducing the compressive strength of the mixes. The fresh and hardened properties of the mixes with encapsulated NaOH were compared with the mix with nano-clay to assess two buildability enhancement approaches (set-on-demand vs traditional). It was found that the buildability enhancement using nano-clay was limited by pumpability constraints, whereas the activation of encapsulated NaOH was limited by compressive strength reductions.

Leaching behaviour of a crystallisation inhibitor in mortars

This paper investigates the leaching behaviour of sodium ferrocyanide, a known crystallisation inhibitor of sodium chloride, which is added to mortars for mitigation of salt decay. Leaching and depletion of the inhibitor is a practical performance related issue that might over time, make the inhibitor less effective against salt decay. In this research, the inhibitor was added to natural hydraulic lime (NHL) mortars during the mixing stage. Leaching of the inhibitor from the hardened mortar was assessed experimentally in laboratory. Both diffusion- and advection-driven transport mechanisms were considered. Diffusion experiments were carried out in a tank leaching test setup. Capillary absorption and drying cycles were used as a driving force to study advection-driven transport. Quantification of the leached species was carried out using various analytical techniques, including UV-VIS spectroscopy, ICP-OES and ion chromatography. The results from the tank leaching test show a high effective diffusion coefficient of ferrocyanide ions, in the same order of magnitude as sodium chloride transport. The advection test shows accumulation of the inhibitor at the evaporative surface and depletion of the inhibitor in the inner layers with successive wet-dry cycles. Based on these results it can be inferred that the degree of inhibitor leaching is significant and needs to be minimised to prolong the positive effect of the inhibitor on mortar durability. Potential solutions to reduce inhibitor leaching are discussed.

Investigating mixer-viscometer techniques for partially filled stirred tanks

Optimising the mixing stage of formulated product manufacture would help with resource utilisation, reducing cost, and developing superior products. However, accurately measuring and characterising mixing dynamics remains challenging. This study explores the use of traditional mixer-viscometer techniques, the Couette analogy and torque curve method, to infer viscosity from torque-speed data during batch mixing processes with partial fill levels (25 %, 62.5 %, 100 %) and varying fluid rheology. The methods yield comparable results in determining the mixer constant, k’, and consistency index, K, and flow index, n, at 100 % fill level but show limitations at lower fill levels due to non-linearity in torque-speed data. Changes in the torque-speed relationship were seen to occur around the point of vortex formation for lower fill levels (Fr > 1). Thus, these data points were excluded in the determination of k’ for 25 % and K and n for 25 % and 62.5 %, but this didn’t improve estimates for apparent viscosity and shear rate for any of the fluids or fill levels. To overcome these challenges, non-linear modelling techniques or data driven models may be required for inferring viscosity from torque at partial fill levels.

Development of the composition and technology of dry drinks based on whey

Dairy and other food industries use whey in the production of various food products. The analysis of the composition of the ingredients used shows that dry demineralized whey is widely used for the production of specialized food products, which is explained by its high organoleptic characteristics, guaranteed quality and safety indicators. The paper considers the possibility of using dry demineralized whey when creating dry drinks for baby food. The results of organoleptic and physico-chemical studies prove the feasibility of using dry juices and plant extracts when creating the composition and formulations of specialized products. The technology of these drinks involves the stage of dry mixing of the components used. It should be noted that poor-quality mixing of micro- and macrocomponents that are heterogeneous in structure and dry matter is the cause of a decrease in the quality of the finished product. To assess the effectiveness of mixing, studies of the ingredients used in the formulation were carried out in terms of indicators: mass fraction of moisture and particle size. Mixing efficiency was evaluated by determining the key component (vitamin C) in the sample and the duration of mixing. Mixing was considered effective if the vitamin C content in each of the five samples was 12.2–14.9 mg. The results of studies of the mixing process show that the effectiveness depends on the set of prescription ingredients and the dispersion of each of them. The results obtained are applicable for the tested conditions of the experiment: a fixed frequency of rotation of the mixer container, the accepted scheme for loading ingredients, the completeness of the useful volume of the container, recipe variation.

Point-to-Point Efficient Grafting Improved Compatibility of Boron-Based Fuel-Rich Propellants.

Due to the high mass calorific value, boron powder is widely used in energetic material systems such as solid propellants and ignition powders. Especially, boron powder has very broad application prospects in the field of fuel-rich propellants. However, due to the cross-linking reaction between the boric acid contained on the surface of boron powder and an adhesive called hydroxylated polybutadiene (HTPB), the viscosity of the propellant mixture system increases sharply, which seriously affects the preparation of the propellant. In this paper, "click chemistry" is intended to be used to graft the functional groups on the surface of boron powder to reduce the viscosity of the boron powder and HTPB in the initial mixing stage. In addition, a rheometer was used to test the viscosity of the boron powder and the HTPB system. The test results showed that compared to the viscosity of the raw boron powder system at 24.1 Pa·s, the mixing termination viscosity of the grafted sample was 17.1 Pa·s, a decrease of 29.0%.

Impact of wideband wavelength conversion on the performance of optical networks

In this paper, it is proposed and numerically tested a 4 −THz guard-band-less integrated all-optical wavelength converter (iAOWC) with two four-wave mixing (FWM) stages. The nonlinear media used in each stage is a waveguide with a tellurite core that is buried into a SiO2 substrate. The core is shaped as two interleaved spirals connected in their centers by two arcs of a circle to minimize bend loss. The iAOWC can continuously shift a 4 −THz WDM bandwidth from the C- to the L-band and vice versa. In the physical layer simulations, 80×28−GBaud, as DP-QPSK and DP-16QAM, 50-GHz-WDM signals were propagated, respectively, through typical distances found in ultra-long-haul and long-haul transmission systems. For up to four wavelength conversions, the penalties imposed on the signals bit-error-ratios by the iAOWCs were negligible. In the network layer simulations, blocking probabilities were estimated in the CORONET and PANEUR topologies supposing an incremental traffic scenario. Physical layer results were fundamental for the parameters (route lengths, wideband conversion, and spectral shift) considered in the network layer analysis. All network links could carry up to 160 wavelengths that extended from C- to L-band. It is shown that by using an iAOWC with bandwidth of 4-THz instead of 1-THz, both with the same spectral shift capability, to match the blocking probabilities achieved with OEOWCs, this would lead to a reduction of 50% and 40% in the number of required devices for the CORONET and PANEUR topologies, respectively. Finally, this is the first time that it is reported a joint analysis of the physical and network layers regarding the impact of wideband wavelength conversion on the performance of optical networks, specially using an integrated all-optical device and under real-world traffic scenarios.

Feasibility assessment of palmitamide derived from waste edible oil as a warm mix asphalt additive

The disposal of waste edible oil (WEO) has become a global challenge with both environmental and economic issues. To provide a novel strategy for the refinement recycling of WEO, this work investigated the feasibility of palmitamide derived from WEO as a warm mix asphalt (WMA) additive. The molecular structure and thermodynamic characteristics of palmitamide were first determined. Following, WMA binders with different palmitamide contents were prepared and their temperature sensitivity and rheological properties were evaluated. Additionally, the engineering performance of WMA mixtures was explored and the environmental benefits of WEO-derived palmitamide were assessed using the gas chromatography-mass spectrometry. The results demonstrate that the phase transition temperature of WEO-derived palmitamide is 98.87 °C, which shows great potential as a WMA additive. Palmitamide provides asphalt workability suitable for construction at relatively low temperatures through reducing the flow activation energy of asphalt. In addition, the moisture damage resistance and deformation resistance of WMA is also improved due to the hydrophobicity and filling effect of palmitamide, respectively. While it is inevitable that palmitamide slightly weakens the fatigue and low-temperature performance of WMA. Moreover, the application of WEO-derived palmitamide can reduce the volatile organic compounds of asphalt in the mixing stage and compaction stage by 40.3% and 30.8%, respectively. The findings contribute to the sustainable development of road engineering and the circular of waste resources.

Study on the relationship between morphological characterizations of dough crumb particles at different mixing stages and noodles quality

To overcome the existing artificial experience evaluation approaches of wheat dough crumb (DC), image processing technique combined migration learning technique has been developed as the precise quantitative on-line evaluation methodology, the core indicator with stacked shaded area (SSA) for DC image evaluation can be used for DC quality evaluation. This study used image characteristics of DC to explore the correlation between noodle qualities at different mixing stages and uniformity of particles. The results showed that the changing regularities of noodle qualities were generally consistent at different mixing stages and finally reached stability. The mean value of SSA of DC showed a highly significant positive correlation with cooking loss (r = 0.93) and a highly significant negative correlation with elasticity and hardness (r = −0.90, r = −0.71) of noodles, indicating that DC can be used to predict noodle qualities. This study is instructive for achieving automatic control of mixing process during noodles production.

Rheological behavior of basalt fiber sprayed cementitious composites (BFSCC)

In the application of modern sprayed cementitious composites, more specific requirements have been proposed for crack resistance, toughness, and durability. By adding fibers with high strength and toughness to the cementitious matrix, the resulting composite material can exhibit excellent mechanical properties. Currently, the commonly used fiber materials of sprayed cementitious composites include steel fiber, polypropylene fiber, basalt fiber. As a type of green and sustainable building material, basalt fiber has been widely used in various engineering projects. In the field of sprayed cementitious composites (SCC), the addition of chopped basalt fibers can enhance its toughness and cracking resistance. However, fiber inclusion may also lead to reduced workability and equipment clogging. Therefore, the rheological behavior of basalt fiber sprayed cementitious composites (BFSCC) under mixing and spraying stages of construction become critical and essential to be fully investigated. In order to simulate the actual engineering application environment of BFSCC, a mortar spraying machine and ICAR rheometer were used to evaluate the variation of key rheological parameters under mixing and spraying stages of construction. The yield stress, plastic viscosity, and thixotropic indices of BFSCC under the influences of basalt fiber characteristics, i.e., type, content and hybrid length, were investigated. The time-dependent rheological behavior of BFSCC was also evaluated. The results indicated that there were significant differences on rheological behaviors under mixing and spraying stages of construction when the basalt fiber was introduced. The spraying process yielded a much higher static and dynamic yield stresses of BFSCC compared with those of mixing stage. Under the same fiber volume content, the plastic viscosity of BFSCC increased first and then decreased with an increase in fiber length in both stages, reaching a maximum at 12 mm. The time-dependent changes in the thixotropic index decreased first and then increased with an increase in time in both the mixing and spraying stages. A prediction model on rheological parameters for BFSCC under mixing and spraying stages was established in accordance with fiber characteristics.

PHASE MORPHOLOGY OF NR, BR, AND EPDM BLENDS PRODUCED BY AN OPTIMIZED SEQUENTIAL MIXING PROCEDURE

ABSTRACT The use of EPDM in NR/BR blends for imparting ozone resistance is well known, as are the challenges of retaining desired mechanical properties in the cured rubber due to uneven distributions of carbon black and cure system across the blended polymer phases, favoring the NR/BR phase. This work explores how different sequential mixing options and mixing intensity can affect polymer phase dispersion and filler distribution, showing that excellent cured physical properties can be obtained using a commercially viable sequential mixing process where a proportion of the filler, cure system, and other compounding ingredients is first mixed into an EPDM masterbatch compound, which is subsequently used in a second mixing stage when it is combined with NR/BR at a suitable level to achieve good ozone resistance. Because only a proportion of the EPDM masterbatch is added to the second mixing stage, further filler, cure system, and other compounding ingredients are also added to reach the desired levels of the final compound. Variations of the sequential mixing process are reported, including the addition of a small amount of BR to the EPDM masterbatch and the use of an extended milling process. This study confirms that sequential mixing allows the retention of carbon black within the dispersed EPDM phase and shows how the EPDM masterbatch composition and the intensity of mixing can influence the phase morphology of EPDM/NR/BR blends. For comparison, an NR/BR control compound, typical of that used in tire sidewalls, is included in the evaluation. By applying transmission electron microscopy and atomic force microscopy imaging, phase domain sizes are evaluated quantitatively, and the Young’s moduli of the rubber phases are determined. The phase morphology is rationalized by the Hansen solubility parameters and the volume fractions of the rubber phases.

Wheat starch particle size distribution regulates the dynamic transition behavior of gluten at different stages of dough mixing

This study investigated the morphology distribution, molecular structure, and aggregative properties variation of gluten protein during dough mixing stage and interpreted the interaction between starch with different sizes and protein. Research results indicated that mixing process induced glutenin macropolymer depolymerization, and promoted the monomeric protein conversion into the polymeric protein. Appropriate mixing (9 min) enhanced the interaction between wheat starch with different particle sizes and gluten protein. Confocal laser scanning microscopy images showed that a moderate increase in B-starch content in the dough system contributed to forming a more continuous, dense, and ordered gluten network. The 50A-50B and 25A-75B doughs mixed for 9 min exhibited a dense gluten network, and the arrangement of A-/B-starch granules and gluten was tight and ordered. The addition of B-starch increased α-helixes, β-turns, and random coil structure. Farinographic properties indicated that 25A-75B composite flour had the highest dough stability time and the lowest degree of softening. The 25A-75B noodle displayed maximum hardness, cohesiveness, chewiness, and tensile strength. The correlation analysis indicated that starch particle size distribution could influence noodle quality by changing the gluten network. The paper can provide theoretical support for regulating dough characteristics by adjusting the starch granule size distribution.

An energy‐based strategy to predict the thickness and content of randomly oriented nanolayers aggregates/agglomerates in thermoplastic polymer nanocomposites: Experimental and analytical approaches

AbstractIn this study, the formation of clay nanolayer clusters inside the high‐density polyethylene (HDPE) matrix was evaluated using a specific strategy based on energy equilibrium in the melt mixing stage. Furthermore, the formed interphase region around nanoparticle domains was precisely evaluated considering the molecular structure of the matrix and linear variation of the physical/mechanical characteristics. The obtained results were used in a developed analytical model to predict the tensile modulus of the nanocomposite system containing randomly oriented nanoparticle domains. The domains consisted of exfoliated, intercalated, or aggregated/agglomerated nanolayers placed in different excluded volumes as the components of an equivalent box model. Different comparative studies were performed using the obtained data from different tests, applied to the prepared HDPE/clay nanocomposite samples, and other data from the literature. It was found that the confrontation between the exerted dispersion energy, by the mixer, and interparticle cohesion energy defined the thickness and physical/mechanical characteristics of the final aggregates/agglomerates in a nanocomposite. Though, the size and content of aggregates/agglomerates increased with the content of initially added nanoparticles. Consequently, the random orientation of each nanoparticle domain and formation of the polymer/particle interphase were proved to have determinative impacts on the mechanical properties of the system.

Implementation of Aseptic Dispensing for Non-Cytostatic Injectable Drugs in the Internal Medicine Inpatient Ward of 'X' Hospital, West Java

Aseptic Dispensing activity is a procedure to minimize pharmaceutical preparations from the threats of pyrogens and contaminants. This study aims to determine the implementation of aseptic dispensing for non-cytostatic injectable drugs and the sterility of intravenous mixed preparations in the Internal Medicine Inpatient Ward of 'X' hospital, West Java for the period January - February 2022. This was a descriptive observational prospective study with a cross sectional approach. Researchers made direct observations of dispensing personnel, room and equipment as well as the process of aseptic dispensing activities including the stages of preparation, mixing, storage and disposal as well as sterility test of aseptic dispensing products. Based on the study results, it was obtained that of the 150 intravenous mixed preparations collected, there were 40 activities of diluting intravenous preparations, 100 activities of packaging into ready-to-use preparations and 10 activities of mixing intravenous preparations into infusion fluids, room suitability by 74%, preparations arrangement procedure by 68%, mixing procedure by 44%, storage procedure by 100% and disposal procedure by 63%. It can be concluded that the aseptic dispensing of non-cytostatic injection drugs in the internal medicine inpatient ward of 'X' hospital, West Java was not in accordance with the guidelines, especially at the mixing procedure stage (≤50). Compliance of dispensing personnel and room cleanliness during the process of mixing intravenous preparations need to be considered. The result of the identification of contamination during the aseptic dispensing activity of non-cytostatic injectable drugs showed that 1 in 150 samples (0.66%) was contaminated.

Drug Phase Transformation and Water Redistribution during Continuous Tablet Manufacturing: A Case Study of Carbamazepine Dihydrate.

In recent years, continuous tablet manufacturing technology has been used to obtain regulatory approval of several new drug products. While a significant fraction of active pharmaceutical ingredients exists as hydrates (wherein water is incorporated stoichiometrically in the crystal lattice), the impact of processing conditions and formulation composition on the dehydration behavior of hydrates during continuous manufacturing has not been investigated. Using powder X-ray diffractometry, we monitored the dehydration kinetics of carbamazepine dihydrate in formulations containing dibasic calcium phosphate, anhydrous (DCPA), mannitol, or microcrystalline cellulose. The combined effect of nitrogen flow and vigorous mixing during the continuous mixing stage of tablet manufacture facilitated API dehydration. Dehydration was rapid and most pronounced in the presence of DCPA. The dehydration product, amorphous anhydrous carbamazepine, sorbed a significant fraction of the water released by dehydration. Thus, the dehydration process resulted in a redistribution of water in the powder blend. The unintended formation of an amorphous dehydrated phase, which tends to be much more reactive than its crystalline counterparts, is of concern and warrants further investigation.

Numerical Simulation of Granular Flow in Concrete Batching Plant via Discrete Element Method

A new giant concrete batching plant with the production capacity of 270m3/hr was designed, analyzed and fabricated. In this concrete batching plant, the granular materials used for high-quality products must be uniformly mixed to attain a homogenous mixture. For this, the discrete element method (DEM) was utilized to simulate the filling, mixing, and discharging processes. The Hertz-Mindlin, elastic-plastic spring-dashpot and Simplified Johnson-Kendall-Roberts (SJKR) models were used for the interaction rules among granular particles. In the light of the aforementioned models, the first simulation with different particle sizes and the second simulation with monosized particles were realized. In the first simulation, the segregation by percolation and momentum segregation were perceived during the bunker filling stage, as well as the seeded granulation, which occurred in the mixer when the radii of particles were not monosized. Furthermore, in the second simulation, convective, diffusive and shear mixing mechanisms were observed and consequently the quantification of the mixing index was calculated using the lacey and miles statistical methods. At last, the active regions formed in the mixer were investigated by taking the velocity of the particles as reference during the mixing stages as well as the mixture throughput from the transfer chute.

Performance of Excavated Sulfur-Rich Soil Stabilized with Binder: A Field Study of Mixing Efficiency

In this study, a mixing procedure of sulfur-rich soil and cement-based binder to enhance the soil’s unconfined compressive strength (UCS) was tested in field conditions for geotechnical applications. The focus was to evaluate uniformity of industrial size soil-binder mixture, blended by existing method. This paper outlined sampling strategy and the number of samples needed for a valid uniformity evaluation. Moreover, this study emphasized the difference between field mixing and laboratory mixture preparation by comparing UCS of stabilized soil samples in the field and UCS of corresponding samples mixed and prepared in the laboratory environment. In the field, soil and cement were blended in two to four stages with 5% and 7% cement—the percentages being based on the soil’s dry weight under field conditions. Samples were taken from the field mixtures after each stage. Since the number of samples needed to be representative of mixture characteristics for large-scale mixing is not standardized, this field experiment included two phases. The first phase was dedicated to finding a sampling strategy for a large soil pile along with measuring UCS of collected samples. In the second phase, sample collection was conducted based on the results of sampling strategy from the first phase. In the laboratory, samples with percentages of binder similar to the amount of binder in the field were also prepared. Both field and laboratory samples were prepared using the tapping method in the laboratory for UCS test. Samples were cured under similar conditions for 28 days. The results showed that the uniformity of mixture improved after each additional mixing stage. In addition, while spots with low UCS were observed in the second mixing step, these spots were eliminated in the third mixing step, and results of the UCS tests were comparatively uniform. Moreover, comparison of the samples revealed that the UCS of the laboratory mixture is higher than that of the field mixture. This showed that even though the UCS is a good standard for comparing the strength of different soils stabilized with different percentages or types of binders in the field mixing, the actual strength of the stabilized mixtures under field circumstances is lower than that in laboratory prepared mixtures.

Formation of nanoparticle aggregates and agglomerates in polymer nanocomposites and their distinct impacts on the mechanical properties

AbstractIn this study, the different effects of nanoparticle aggregates and agglomerates on the mechanical properties of polymer nanocomposites are comprehensively investigated. To this end, a specific strategy, based on the equilibrium between the dispersion and cohesion energies in the mixing stage, is proposed using which the content and size of aggregates/agglomerates can be defined. The aggregated/agglomerated networks are considered to place in constrained volumes (CVs), having co‐continuous morphology. An equivalent box model (EBM), corresponding to the system, is used to predict the tensile modulus of the nanocomposite. Different test results of HDPE nanocomposite samples, containing 1–3 wt.% of surface‐modified silica nanoparticles, prepared by a semi‐industrial single screw extruder, are applied to validate the model. Moreover, other data from the literature are also used to further evaluate the accuracy and capability of the proposed analytical method.

Role of carboxymethyl cellulose binder and its effect on the preparation process of anode slurries for Li-ion batteries

We systematically investigate the role of carboxymethyl cellulose (CMC) and show how it affects the slurry dispersion according to the slurry preparation process. We find that CMC plays various roles as a dispersant, thickener, and gelling agent in the anode slurry depending on its content. CMC acts as a dispersant at lower content than the optimum graft density at which the two particles (carbon black, graphite) are adsorbed and saturated. When the CMC content increases above the optimum graft density, the adsorbed CMC still acts as a dispersant, but the extra free CMC acts as a thickener or a gelling agent depending on the content. In the meanwhile, CMC shows similar adsorption and dispersion mechanism for the two particles. Therefore, at a CMC content lower than the optimum graft density, the adsorption selectivity of CMC for both particles is significantly affected by the mixing sequence of CMC and two particles, resulting in a significant difference in slurry dispersion. On the other hand, at higher CMC content, the slurry dispersion is rarely affected by the CMC mixing sequence as both particles are eventually adsorbed and saturated in the final mixing stage. This study reports for the first time that the adsorption selectivity of the binder for the two particles can be controlled through the slurry preparation process, and that the slurry dispersion can be differently affected by the preparation process depending on the binder content.
