The Influence of Peat Water on the Physical Properties of Underwater Concrete

Casting concrete underwater is concrete used for structural work underwater. The main problem in underwater casting is the separation of concrete constituent materials. Casting underwater also does not involve compaction. This study will examine the effect of peat water on the physical properties of underwater cast concrete. The additive used in this study is in liquid form, with a mixture of anti-washout material 1.8% and self-compacting concrete 5% to the weight of cement. The obtained slump flow value is 470 mm. The results of volume weight testing on variations of clean water mixtures immersed in clean water for seven days are 2248,14 kg/m3 and 2258,96 kg/m3 for 28 days, variations of clean water mixtures immersed in peat water for seven days are 2224,49 kg/m3 and 2219,39 kg/m3 for 28 days, and variations of peat water mixtures immersed in peat water for seven days are 2202,50 kg/m3 and 2191,08 kg/m3 for 28 days. The decrease in volume weight occurs in variations immersed in peat water. The results of porosity testing on 7-day and 28-day concrete age variations of peat water mixtures immersed in peat water are 9,94% and 10,78%, variations of clean water mixtures immersed in peat water are 9,84% and 10,28%, and variations of clean water mixtures immersed in clean water are 9,73% and 8,70%. The SEM test results show the surface shape of concrete using a magnification of 1000x, more pores on variations of peat water mixtures immersed in peat water, and variations of clean water mixtures immersed in peat water have uneven surfaces and pores. In contrast, variations of clean water mixtures immersed in clean water have better surfaces. The additive used can work well with peat water and clean water.

Computational analysis of hydrogen bonds network dynamics in the water layers surrounding Aβ(1-42) and Aβ(1-40) peptide dimers

The amyloid-β peptide (Aβ) dimer is involved in the development of Alzheimer’s disease through forming amyloid plaques. Aβ(1-40) and Aβ(1-42) are the most common and poisonous species causing Alzheimer’s disease. They form homogeneous dimers containing two similar peptides and heterogeneous dimers containing different ones. The low molecular weight, fast dynamics, and varying compositions of these dimers make it difficult to study them by conventional experimental methods. Hence, we clarify the effect of the diversity of the Aβ dimers on the structure of the water molecules around the peptides by the molecular dynamics (MD) simulation method in this study. MD simulations of the Aβ(1-40) and Aβ(1-42) monomers are also performed for the comparison. The calculations are repeated in the presence of dimethyl sulfoxide (DMSO). The water molecules positioned at distances of 0.5, 0.75, 1, 1.25, and 1.5 nm from the protein were chosen to investigate the distribution and dynamics of hydrogen bonds in the layers surrounding the peptide. The results show that the heterogeneity of the dimer system increases the percentage of hydrogen (H) atoms not involved in any water-water hydrogen bonds around the peptides in the different layers. While it decreases the percentage of H atoms involved in one and two water-water hydrogen bonds. The DMSO presence reduces the percentage of H atoms involved in two hydrogen bonds in the systems containing a mixture of water and DMSO. The average interaction energy of the dimers demonstrates the enhanced interactions of the two peptides in water in comparison with that in the mixture of water and DMSO. The behavior of the water molecules around the heterogeneous dimer is very similar to that around the Aβ(1-42) homogeneous dimer.

Pergaruh Rendaman Pada Marshall Campuran AC-BC Limbah Ban Karet Bekas Sebagai Agregat Pengganti

Utilization of new technologies in asphalt mixture production includes soaking technologies that can enhance mechanical properties of the mixture. This research aims to evaluate pavement vulnerability to water and the environmental quality impact due to waste from used rubber tires as an effort to strengthen pavements by substituting asphalt. The variables studied are variations of used rubber tire waste at 0%, 2%, 3%, and 4% replacing asphalt content in AC-BC mixtures. Testing was conducted using the Marshall method by soaking the mixtures in water for normal duration, 30 minutes, 24 hours, and 72 hours. The test results indicate that higher percentages of used rubber tire waste and longer soaking durations lead to a decrease in AC-BC mixture characteristics. The Marshall value of the AC-BC mixture with 2% used rubber tire waste was found to be superior compared to mixtures with 0%, 3%, and 4%. From the data analysis conducted, it can be concluded that water has a negative influence on the Marshall value reduction of mixtures containing used rubber tire waste, correlating with increased soaking duration.

Investigation of combination of heat storage container and thermosyphon solar system in existence of nanomaterial

This research explores the combination of fins into thermosyphon solar collectors to enhance energy efficiency. The storage system includes a finned container filled with nanomaterial (a blend of Al2O3 nanoparticles and paraffin (RT30)), while the fluid circulating within the tube consists of a homogeneous mixture of copper nanoparticles and water. Unsteady laminar flow within a three-dimensional domain, incorporating gravitational forces, has been modeled. The numerical approach has undergone rigorous validation, demonstrating strong agreement with both experimental and numerical data. Effects of fin installation and nano-powder dispersion have been investigated across various scenarios. At t = 60 min, the liquid fraction (LF) is approximately 2.08 times higher in the system with fins compared to the simple case. LF progressively increases over time, reaching a value 3.1 times higher at t = 60 min compared to t = 30 min. The temperature of the nanofluid in the tank rises over time. Despite the enhanced nanofluid temperature in the tube due to fin presence, a decrease occurs within the domain due to accelerated melting rate in the container. Incorporation of nanoparticles into paraffin shows an improvement in LF by approximately 11.66 % in the presence of fins.

Agro-waste derived sulfonated biochar material as a sustainable heterogeneous catalyst for conversion of fructose to 5-hydroxymethylfurfural

BackgroundDevelopment of biomass derived solid acid catalysts has the advantage to conform the green chemistry protocol for production of 5-hydroxymethylfurfural (HMF) by dehydration of fructose. MethodWe have reported waste cashew nut shell produced char as a biochar to prepare sulfonated biochar (SBC) catalyst by incorporating –SO3H group through treatment of concentrated sulfuric acid. Significant findingsDifferent methods of characterization including XRD, FT-IR, XPS, FESEM-EDS, TEM, TPD and BET analysis, were used to study the structure, morphology, chemical compositions, acidity and porosity of the produced SBC catalysts. The mesoporous nature of the material was confirmed by the powder X-ray diffraction patterns (PXRD), type IV isotherm (BET), and flakes-like structure was observed in TEM analysis. The catalyst showed high yield of HMF (92%) under optimum conditions of 120 °C in 60 min under biphasic solvent mixture of water and toluene (1:2). High yield could be explained by high acid strength of catalyst as observed by NH3-TPD analysis. Leaching test by Sheldon's method and recyclability experiment proved the need and heterogeneity of the present catalyst.

A measurement method for zero-degree thermostat

Thermocouple thermometers are widely used in laboratories and industry, the ice-water mixture is usually used as cold end compensation for thermocouple thermometer measurement. However, the ice-water mixture has disadvantages, such as complex manufacturing process, short use time, and unstable internal temperature field. The zero-temperature thermostat can replace the traditional ice water mixture to provide a stable temperature field environment. However, there is no suitable measurement method that can evaluate the zero-degree thermostat to meet the measurement requirements of thermocouple thermometer. Therefore, comparative experiments on temperature deviation, volatility, axial temperature field uniformity, radial temperature field uniformity, and load characteristics of the ice-water mixture and the zero-temperature thermostat are evaluated. In addition, the uncertainty of the zero-temperature thermostat and the ice water mixture is also proposed. The results reveal that the measurement results of temperature deviation, volatility, axial temperature field uniformity and load characteristic of the zero-temperature thermostat is smaller than that of the ice water mixture. Meanwhile, the uncertainty results also reveal that the zero-temperature thermostat is more stable than the ice water mixture. This study provides a comprehensive method for evaluating the performance of zero temperature thermostats, which can be used to verify the accuracy of the instrument and ensures the reliability of the thermocouple thermometers measurement, and promotes the development of zero temperature thermostat in temperature measurement field.

Investigating the properties of nanoparticles from heveabrasiliensis shell for coolant application in PEMFCs

Extensive consumption of petroleum-based products, which has resulted in energy depletion, prompted a need to seek alternative and renewable means of transportation. PEMFCs can achieve high power density, low operating temperatures, rapid start-up, and clean energy, making them ideal for transportation. Several studies have demonstrated that conventional cooling agents, such as water or water with ethylene glycol, do not dissipate heat efficiently in PEMFCs, resulting in deteriorating performance and a shortened operational lifespan over time. The incorporation of bio-sourced nanofluids as an alternative coolant for Proton Exchange Membrane (PEM) fuel cells is the newest venture to take over PEM fuel cell development. Utilizing bio-sourced nanofluids is being evaluated for elevating the heat conduction and decreasing the electrical conductivity of proton exchange membrane fuel cells (PEMFCs). The objective of this article is to investigate Hevea brasiliensis Shell (HBS)-based nanofluids dispersed in water and Ethylene glycol (EG) at varying concentrations of 0.1 vol%, 0.3 vol%, and 0.5 vol% by paying attention to improving heat transfer, extracting high electrical output, reducing pump loss, and increasing the longevity of cells. As an adverse effect, incorporating HBS at a 0.5 % volume concentration within an 80:20 mixture of water and ethylene glycol (W:EG) resulted in an 8 % improvement in heat transfer and a 77 % increase in electrical conductivity when compared to W:EG (80:20), which is promising as a pertinent cooling technique for PEMFC stacks.

Energy, Exergy, and Economic Analysis of a New System for Simultaneous Power Production and Cooling Operating with an Ammonia–Water Mixture

This paper presents the energy, exergy, and economic analysis of a new cogeneration cycle for the simultaneous production of power and cooling operating with an ammonia–water mixture. The proposed system consists of an absorption cooling system integrating a reheater, a separation tank, a compressor, a turbine, and an expansion valve. In addition, internal rectification is applied, improving the system’s performance. Mass, energy, and exergy balances were applied to each system’s component to evaluate its performance. Additionally, the costs of each component were determined based on economic equations, which take into account mass, heat flows, and temperature differences. A parametric analysis found that the system reached an energy utilization factor of 0.58 and an exergy efficiency of 0.26 using internal rectification at TG = 120 °C, TA = 30 °C, and TE = 10 °C. The power produced by the turbine was 26.28 kW, and the cooling load was 366.8 kW. The output costs were estimated at 0.071 $/kW. The condenser was found to be the most expensive component of the system, contributing 28% of the total cost. On the other hand, it was observed that the generator was the component with the highest exergy destruction, with 38.16 kW.

A facile synthesis of bimetallic Ni/Co-BTC hollow MOFs for effective removal of congo red

ABSTRACT In this work, we employ an eco-friendly and highly efficient method for the successful removal of anionic azo dye (CR) using emerging Ni/Co-BTC hollow Metal-Organic Frameworks (MOFs). The MOFs was developed via a solvothermal synthesis method. Various kinetic models, adsorption capacities, isotherms (Langmuir and Freundlich), and thermodynamic stability assessments were used to predict the adsorption mechanism and the types of interactions present between CR dyes and Hollow MOFs. Our findings suggest that the adsorption process follows Freundlich isotherm, with PSO kinetic models indicating chemisorption and a maximum Langmuir adsorption capacity of 168.03 mgg−1. We observed a removal efficiency of 74% in neutral medium and 85% in acidic medium. Thermodynamic studies reveal the spontaneity of the process with endothermic enthalpy, attributed to the hydrogen bonding and electrostatic interactions between the dye molecule and the adsorbent. Furthermore, to investigate practical applicability, we conducted studies in real water and dye mixtures. All studies demonstrated that the prepared Ni/Co-BTC hollow MOFs show promising potential adsorbents for the CR dye removal from the wastewater, owing to their high efficiency and reusability.

Innovative TiO2-doped polyvinyl alcohol sponge for efficient oil–water separation and dye degradation in wastewater treatment

Regular problems faced due to oil spills and soluble contaminants have increasingly caused serious water pollution. Therefore, there is an urgent need to develop efficient strategies to purify wastewater. This study aims to formulate a synergistic treatment technology of sorption and ultraviolet light catalysis for oil–water separation and degradation of dyes in wastewater. In this study, TiO2 doped PVF sponge (DTMS-TiO2@PVF) was prepared with a water contact angle of 151.5° and a removal rate of 98.86 % of MB in 120 min. Meanwhile, DTMS-TiO2@PVF sponge could easily realize the selective separation of oil–water mixtures. Its saturated sorption capacity for oil and organic solvent was 4.13–10.05 g/g. In addition, DTMS-TiO2@PVF sponge had better environmental stability, which could withstand chemical corrosion (acid, alkaline, and salt solutions). Therefore, DTMS-TiO2@PVF sponge showed great potential for application as an efficient oil–water separation and photocatalytic material, especially in the field of treating oil wastewater and water purification.

Plant cell wall inspired lignin-based membrane with configurable radical scavenging activity

Natural antioxidants have received considerable attention due to their inherent biocompatibility and biodegradability, yet inferior antioxidant, storage instability, and structural heterogeneity limit applications. Drawing inspiration from plant structures, we develop antioxidant membranes that are entirely biomass-derived, metal-free, and customizable, using the layer-by-layer (LBL) assembly technique. The natural polyphenolic lignin co-assembles with lauryl alcohol derived from cassia bark into macroporous spherical particles in a γ-valerolactone (GVL)/water mixture, in which the pore size can be facilely adjusted by modulating feed ratio. Furthermore, the lignin nanospheres’ free radical scavenging ability is greatly enhanced by enlarging the pore size, offering an alternative way to improve the antioxidant performance. As the hydrophilic shells of lignin spherical assemblies display a strong affinity towards holocellulose nanofibrils (HCNF), multilayered antioxidant membranes with stable mechanical strength are constructed. The entirely biomass-derived antioxidant membrane has proven effective in recycled antioxidative microfiltration applications, demonstrating more than 90 % scavenging activity over seven cycles. Moreover, it exhibits biodegradability even in harsh conditions, with temperatures below 280 K and relative humidity less than 30 RH%. This work illuminates new possibilities for applying natural antioxidants in precise control materials.

Drying-Induced Flash Nanoprecipitation in a Sessile Drop: A Route to Synthesize Polymeric Nanoparticles.

Flash nanoprecipitation is a simple and scalable method to produce nanoparticles by rapid mixing of a polymer solution with an antisolvent. High-speed mixing devices for the continuous synthesis of polymeric nanoparticles and drug-encapsulated nanoparticles have been designed. In this work, we demonstrate a different approach to induce flash nanoprecipitation using the differential evaporation of solvents in a sessile drop. To show proof of concept, we use polymethyl-methacrylate (PMMA) dissolved in a tetrahydrofuran (THF)-water mixture as a model system. A sessile drop of the polymer solution is allowed to dry under controlled conditions. The sessile drops of the PMMA-THF-water ternary mixture are observed to dry in the constant radius mode. As THF in the drop evaporates faster than water, PMMA supersaturates and precipitates as nanoparticles. Although coffee-ring formation is well-studied in the drying of colloidal suspensions, this work demonstrates the formation of nanoparticles in situ due to a change of solvent quality and subsequent deposition of particles at the pinned contact line. Using the theory of drying of binary solutions, we calculate the temporal variation of composition. The drying paths passing through the low-concentration branch of the binodal give rise to nanoparticles, whereas those passing through the high-concentration branch yield porous films. Spherical polymeric nanoparticles in the size range of 250-700 nm were synthesized using this technique starting from drops with different initial polymer concentration. The method is a cost-effective (no high-speed mixing is required) and scalable alternative to conventional flash nanoprecipitation for synthesizing polymeric nanoparticles for potential applications in drug delivery, diagnostics, and polymer recycling.

Then, according to the modified silicone polymers or molecules, we give a detail description of their synthesis and briefly introduce the main reactions with the substrate, the typical grafting strategy and fabricating methods. Subsequently, the performance and oil–water application of various hydrophobic membranes modified silicone are introduced. Finally, some problems and challenges faced by silicone modification are summarized and present, and their future development is also prospected.

Thymus schimperi Ronniger plant flower extract dye-sensitized solar cells

The demand for energy is greatly increasing due to the world’s population growth and technological advancement. Natural dye-sensitized solar cells are attracting research as an alternative and renewable energy source due to their simple preparation technique, availability, cost effectiveness and environmental friendliness. In the present work, we have successfully fabricated dye-sensitized solar cells (DSSCs) from Thymus schimperi Ronniger plant flowers for the first time. The solvents used for extraction of the flower dye were deionized water and its mixture with ethanol. The T. schimperi Ronniger flower extract dye solutions and sensitized photoanodes were characterized by Fourier transform infrared and ultraviolet–visible techniques. The crystallinity of TiO2 films was analyzed by x-ray diffraction, and the films showed pure anatase phase behavior. The photoelectrochemical solar cell performance parameters, such as short circuit current density, open circuit voltage, fill factor and efficiency, were evaluated from current density–voltage measurements using a Keithley 2450 source meter. DSSCs sensitized with dye solution extracted by a mixture of water and ethanol showed better performance (1.37%) than those sensitized with dye solution extracted by deionized water alone (1.02%).

Facile dip-coating of silk fibroin/tannic acid@CaCO3 hybrid film with superhydrophilicity on the surface of polypropylene nonwovens for oil–water separation

Superhydrophilic membrane materials are widely used for oil/water separation due to their excellent resistance to anti-fouling underwater. The key factors for realizing superhydrophilicity of membranes are the introduction of hydrophilic groups and the construction of surface micro/nano roughness structures. Herein, we propose a simple, mild, and green dip-coating method to prepare silk fibroin (SF)-tannic acid (TA)@CaCO3 hybrid film to achieve superhydrophilicity of polypropylene nonwovens (PP). Specifically, the hydrophobic interactions between SF and hydrophobic materials were used to create the pre-coatings. TA molecules were deposited onto the surface of SF via hydrogen bonding to provide phenolic hydroxyl groups for achieving the hydrophilicity of PP membranes. Then, the CaCO3 was synthesized in situ by introducing Ca2+ into the pre-coating while depositing TA to construct micro/nano-roughness structures on the PP membrane surface for obtaining superhydrophilicity. PP-SF-TA@CaCO3 membranes exhibit outstanding superhydrophilicity and underwater superoleophobicity, with separation efficiencies exceeding 99 % for a variety of oil–water mixtures and oil-in-water emulsions, and water fluxes ranging from 4000 L m-2h−1 to 5500 L m-2h−1. The separation efficiencies remained above 99 % throughout 50 separation cycles, indicating the excellent separation stability of the modified membranes. Moreover, no significant loss of separation efficiency was observed when separating oil mixtures from harsh water sources, including acidic, alkaline, cold, and hot water. Therefore, the membranes modified by the above process have a promising application in the practical separation of oily wastewater.

EFFECTS OF DIFFERENT COOLANT MEDIA ON THE COOLING PERFORMANCE OF INJECTION MOLD PRODUCT

The injection molding process involves heating a thermoplastic polymer above its melting point and injecting it into a mold. The polymer then cools and solidifies to form the final part. The process consists of four stages: clamping, injection, cooling, and ejection. Among these stages, cooling plays a crucial role as it requires an efficient cooling system to transfer heat from the mold at a consistent rate, ensuring high-quality final products. This project specifically focuses on investigating the impact of different cooling media used in the cooling system for the mold. The aim is to compare the effectiveness of various cooling media on the cooling performance of the injection-molded product. Different types of coolants, including water, oil, or other solution mixtures, have been considered for their ability to reduce or regulate the temperature of the system. CAD modeling was prepared for the case study, along with a pre-designed conformal cooling channel and gating system. After conducting the simulation analysis, water emerged as the most effective coolant, demonstrating superior results compared to other coolant options. The results also highlight the feasibility of using alternative coolants that offer comparable cooling performance.

Terahertz Sensing of L-Valine and L-Phenylalanine Solutions.

To detect and differentiate two essential amino acids (L-Valine and L-Phenylalanine) in the human body, a novel asymmetrically folded dual-aperture metal ring terahertz metasurface sensor was designed. A solvent mixture of water and glycerol with a volume ratio of 2:8 was proposed to reduce the absorption of terahertz waves by reducing the water content. A sample chamber with a controlled liquid thickness of 15 μm was fabricated. And a terahertz time-domain spectroscopy (THz-TDS) system, which is capable of horizontally positioning the samples, was assembled. The results of the sensing test revealed that as the concentration of valine solution varied from 0 to 20 mmol/L, the sensing resonance peak shifted from 1.39 THz to 1.58 THz with a concentration sensitivity of 9.98 GHz/mmol∗L-1. The resonance peak shift phenomenon in phenylalanine solution was less apparent. It is assumed that the coupling enhancement between the absorption peak position of solutes in the solution and the sensing peak position amplified the terahertz localized electric field resonance, which resulted in the increase in frequency shift. Therefore, it could be shown that the sensor has capabilities in performing the marker sensing detection of L-Valine.

Experimental Characterization of Hydronic Air Coil Performance with Aluminum Oxide Nanofluids of Three Concentrations

This paper presents the continuation of experimental investigations conducted by the present authors to measure and compare the thermal and fluid dynamic performance of a residential hydronic air coil using nanofluids. The prior experiments were limited to testing only one volumetric concentration (1%) of aluminum oxide (Al2O3) nanofluid. They compared it with the base fluid, a 60% ethylene glycol/40% water mixture by mass (60% EG). The original tests revealed some deficiencies in the experimental setup, which was subsequently revised and improved. This paper summarizes the results of experiments from the improved test bed using three concentrations of Al2O3 nanofluids: 1, 2, and 3% volumetric concentrations prepared with an average particle size of 45 nm in a 60% EG dispersion. The test bed in these experiments simulates a small air handling system typical of heating, ventilation, and air conditioning (HVAC) applications in cold regions. Entering conditions for the air and liquid were selected to emulate typical commercial air handling systems operating in cold climates. Contrary to previous findings, our test results revealed that nanofluids did not perform as well as expected. Prior predictions from many analytical and numerical studies had promised significant performance gain. The performance of the 1% nanofluid was generally equal to that of the base fluid under identical inlet conditions. However, the performance of the 2% and 3% nanofluids was considerably lower than that of the base fluid. The higher concentration nanofluids exhibited heat rates up to 14.6% lower than the 60% EG and up to 44.3% lower heat transfer coefficient. The 1% Al2O3/60% EG exhibited a 100% higher pressure drop across the coil than the base fluid, considering equal heat output. This performance degradation was attributed to the inability to maintain nanofluid dispersion stability, agglomeration, and subsequent decline in the thermophysical properties.

Correlating Substrate Reactivity at Electrified Interfaces with the Electrolyte Structure in Synthetically Relevant Organic Solvent/Water Mixtures.

Optimizing electrosynthetic reactions requires fine tuning of a vast chemical space, including charge transfer at electrocatalyst/electrode surfaces, engineering of mass transport limitations, and complex interactions of reactants and products with their environment. Hybrid electrolytes, in which supporting salt ions and substrates are dissolved in a binary mixture of organic solvent and water, represent a new piece of this complex puzzle as they offer a unique opportunity to harness water as the oxygen or proton source in electrosynthesis. In this work, we demonstrate that modulating water-organic solvent interactions drastically impacts the solvation properties of hybrid electrolytes. Combining various spectroscopies with synchrotron small-angle X-ray scattering (SAXS) and force field-based molecular dynamics (MD) simulations, we show that the size and composition of aqueous domains forming in hybrid electrolytes can be controlled. We demonstrate that water is more reactive for the hydrogen evolution reaction (HER) in aqueous domains than when strongly interacting with solvent molecules, which originates from a change in reaction kinetics rather than a thermodynamic effect. We exemplify novel opportunities arising from this new knowledge for optimizing electrosynthetic reactions in hybrid electrolytes. For reactions proceeding first via the activation of water, fine tuning of aqueous domains impacts the kinetics and potentially the selectivity of the reaction. Instead, for organic substrates reacting prior to water, aqueous domains have no impact on the reaction kinetics, while selectivity may be affected. We believe that such a fine comprehension of solvation properties of hybrid electrolytes can be transposed to numerous electrosynthetic reactions.
