Morphology and Mechanical Properties of High Density Polyethylene and Ethylene-Methyl Acrylate Copolymer Blends with Organoclay

In this research, the effect of ethylene-methyl acrylate copolymer (EMAC or EMAC30) and clay surface modified with aminopropyltriethoxysilane 0.5-5 wt% and octadecylamine 15-35 wt% (Clay-ASO) on the morphological, mechanical, and thermal properties of high density polyethylene (HDPE) were investigated. The polymer blends and composites were prepared by an internal mixer and then samples were molded by compression molding. The morphology analysis showed that the presence of fibrous surface at the specimen fracture surface of HDPE/EMAC30 blends. The phase morphology of HDPE blends with Clay-ASO 3, 5 and 7 phr was observed the phase separation of EMAC30 and aggregate of Clay-ASO at high EMAC30 content. Young’s modulus of HDPE/Clay-ASO composites increased with increasing Clay-ASO composites. The presence of Clay-ASO did not improve Young’s modulus and tensile strength of HDPE/EMAC30/Clay-ASO composites. The strain at break of HDPE/EMAC30 blends increased with increasing EMAC30 content. The incorporation of EMAC30 and Clay-ASO had no effect on the melting temperature of HDPE blends and composites, respectively. The percent crystallinity of HDPE/EMAC30 and HDPE/EMAC30/Clay-ASO was lower than that of pure HDPE. The addition of EMAC30 and Clay-ASO decreased the degradation temperatures of HDPE/EMAC30 blends and composites.

Effect of Zeolite Mineral on the Formulation of a Wood-plastic Composite

The present work studies the positive or negative effect of zeolite mineral on the tensile and flexural mechanical behavior of a wood-plastic composite. Eight different blends were developed, the components used were wood flour (WF), polypropylene (PP), zeolite (Z) and maleic anhydride modified polypropylene (MAPP) as coupling agent. The eight blends were made using a counter-rotating twin-screw extruder, while the specimens were produced on a plastic injection molding machine with a 60ton clamping capacity. The standards used to determine the tensile and flexural mechanical properties were ASTM 638 and ASTM 790, respectively. Ten repetitions of each mixture were carried out. In addition, a reference (100% polypropylene) was used to compare the results obtained to determine whether the effect of using the zeolite mineral generated positive or negative results in the compounds obtained. Both studies showed that as the proportion of zeolite increases in the blend, the tensile and flexural properties are affected. However, the mixture (M7) with proportions in its components of, 34.375% WF, 55.875% PP, 6.75 % Z and 3% MAPP, showed an increase in the tensile and flexural mechanical properties, indicating a strong relationship between the components that integrate the wood-plastic composite (WPC), mainly between wood and mineral.

Investigation of anaerobic digested pyrolysis oil and waste derived biodiesel blends as sustainable fuel for marine engine application

In anaerobic digestion (AD) plants around 40% of the feed waste is utilised for biogas generation while the remainder is used as a fertiliser that is rich in oil that could be further utilised through pyrolysis. Dry AD waste, subjected to intermediate pyrolysis, generated a digested pyrolysis oil (DPO) of high viscosity (473 mm2/s) and low energy content (26 MJ/kg). To improve its fuel characteristics, we blended DPO with either used cooking oils (high in unsaturated fatty acids) or lamb fat (high in saturated fatty acids) using solvents of differing polarity including alcohols varying in chain length and hence aqueous miscibility from C1(methanol) to C5 (pentanol) and diethylether (DEE, a non-polar solvent). Five blends were prepared, typically consisting of 10–20% DPO, 20% solvent (alcohol or DEE) and 60–70% cooking oil or lamb fat. Physical properties of DPO blends e.g., viscosity, density, heating value, total acid number and flash point were found to be lower than neat DPO but increased about 25–40% over a storage period of 8 months. The blends were more stable than neat biodiesel as assessed by FT-IR spectroscopy. The elemental analysis (C, H, N, S and O) showed that atomic ratio of DPO blends; H:C, H:O, H:N and C:N were found to be lower than biodiesel and DPO fuels, respectively. Overall, the properties of DPO blends met the Marine Fuel Standard (Marine ISO 8217) and hence could be considered as a suitable replacement for bunker oil to protect marine environments following further testing and scale up studies.

Rheological and tribological behaviour of nanofluids: an experimental evaluation

Commercially available synthetic engine oils of SAE grades 5W40 were taken as base fluids for preparing nano fluids by blending 0.1% and 0.2% concentration by weight of the functionalized Cu and MoS2 nanoparticles in them. The base fluids and their blends were characterized using standard ASTM and IS testing methods for their physicochemical and tribo performance behaviours. The rheological studies were performed on a Rheometer while the tribological investigations were performed on tribo-tester. The study reveal that a small improvement in anti- friction behaviour of about 6% and 4% reported for the 0.2 wt% of Cu and MoS2 nanoparticles respectively in the tested lubricants indicate that finished products have little scope to improve anti-friction properties under the influence of already present additives, however anti-wear properties showed significant enhancement up to 20% for 0.2% MoS2 and up to 15% for 0.2% nano-Cu indicating better anti-wear properties of MoS2 and Cu nanoparticle blends. Rheological studies reveal that blending of nanoparticles has marginal influence on the rheological behaviour of the lubricants. The lubricants show shear thinning behaviour at low shear rates. However at higher shear rates, lubricants behave as Newtonian fluids.

Phytochemical, physical and functional properties of flour blends produced from wheat, unripe plantain and pigeon pea

This study investigated the phytochemical, physical and functional properties of flour blends produced from wheat, unripe plantain and pigeon pea, suitable for purposes of formulating food composition table for the flour blends by homogenously mixing wheat, pigeon pea and unripe plantain flour in the proportion of wheat flour (100%) 100:0 (WHF), wheat-pigeon pea flour 95;5:0 (WPF),wheat-unripe plantain-pigeon pea flour 85:10.5 (WPU1), wheat-unripe plantain-pigeon pea flour 75:15:10 (WPU2)and 65:20:15 (WPU3) respectively. WHF represent 100% wheat flour served as control. There was a significant difference (p<0.05) among samples of flour blends (WHF), (WPF),(WPU1), (WPU2) and (WPU3).The results obtained for proximate composition, phytochemical and functional analysis ranged: crude fiber (2.90-4.07%), protein (10.10-14.50%), moisture (5.00-10.50%), ash (0.50-0.7%), fat (2.04-3.50%), carbohydrate(67.95-79.26%), saponins (0.46-2.97 mg/100g), flavonoids (4.50-4.70 mg/100g), tannins(0.80-1.26 mg/100g) phenols (1.00-1.50 mg/100g), bulk densities (0.41-8.20g/cm3), emulsion capacity (9.20-5.20%), foaming capacity (2.90-10.60%), water absorption capacity (6.20-6.60g/g), oil absorption capacity (0.10-8.50%) and swelling capacity (25.00-29.00%) respectively. The results showed that incorporation of pigeon pea flour into wheat flour significantly (p>0.05) increased the protein, fibre and fat content of composite flour. As the ratio of wheat decreases and increase in the unripe plantain and pigeon pea, the carbohydrate content decreases significantly. WHF shows higher carbohydrate content among samples. This is evident that wheat has high carbohydrate content. Based, on the result from this study, it can be concluded that flour formulation from different four blends can improve the nutritional values of flour blends and reduce anti-nutrients drastically.

Application of pilot‐scale molecular distillation for enrichment of phytonutrients from a novel deodorizer distillate of the margarine and shortenings industry

AbstractBackgroundA wiped‐film molecular distillation (WFMD) pilot plant was used to evaluate process conditions for enriching phytonutrients (PN) from a novel vegetable oil deodorizer distillate (VODD) of the margarine and shortenings industry. This byproduct results from the incorporation of new blends of vegetable oils, such as soybean and palm oil, making it of interest due to its distinct chemical composition and matrix, which differ from those of deodorizer distillates studied previously. The significance of the present investigation is related to the properties of the oil blend, requiring the establishment of new process conditions for this specific VODD. Experimental design was used to evaluate the WFMD process variables, with the aim of removing free fatty acids and enabling eight PN to be concentrated in the reprocessing stages.ResultsThe product obtained after three WFMD stages presented a fivefold increase in the total PN concentration, compared to the raw material. Notably, the procedure provided enrichment ratios of 7.2‐fold for total tocopherols (including α‐, β‐, λ‐ and δ‐tocopherols), 4.5‐fold for total phytosterols (including campesterol, stigmasterol and β‐sitosterol) and 1.2‐fold for squalene, together with a deacidification efficiency of 78.93%.ConclusionThe proposed process provided significant concentration gains for all eight PN evaluated, resulting in a value‐added product. These excellent results were achieved using only three WFMD stages, without any need for additional processing steps. The data obtained at the pilot scale provide valuable insights for predicting the scalability of the process and facilitating potential industrial implementation. © 2023 Society of Chemical Industry.

Physicochemical and thermal characterization and antioxidant property of chicken feather keratin and ginger starch hybrid nanocomposite film

The fabrication of starch-based nanocomposites is regarded as a sustainable method of manufacturing ecologically favourable packaging materials in addition to their better gaseous barrier attribute over starch films. The present study assessed the physicochemical and thermal characterization as well as antioxidant property of a starch-keratin nanocomposite blend fabricated from ginger starch and chicken feather keratin. Starch-keratin nanocomposite films composed of 90:10 and 70:30 ginger starch:chicken feather keratin were fabricated and analysed. The physicochemical characteristics such as moisture content, transparency, water solubility, and water vapour permeability decreased significantly by 22.67 %, 15.06 %, 12.95 %, and 1.40 %, respectively, with a higher keratin level in the film. The tensile strength by 18.84 % with increasing starch content, while the elongation at break was highest in the 90:10, followed by 70:30 film and starch film without keratin, respectively. The absorption spectra representing OH vibrational stretching band in ginger starch was shifted from 3252.4 cm−1 (S) to 3296.4 cm−1 (S-K, 90:10) and 3294.6 cm−1 (S-K, 70:30) while the CH stretching vibration was shifted from 2929.6 cm−1 (S) to 2928.4 cm−1 (S-K, 90:10) and 2923.5 cm−1 (S-K, 70:30). The degree of amorphousity of the film increased with increasing keratin content. The optimum degradation temperatures was reduced from 244.0 °C to 236.8 °C with increasing keratin content. The crystallisation temperature in the starch-keratin nanocomposite film, though higher than those of starch and keratin, was reduced from 286.3 °C (S-K, 70:30) to 266.0 °C (S-K, 90:10). The antioxidant property of the film was significantly higher in the 70:30 film compared to 90:10. Overall, the starch-keratin nanocomposite film presented improved physicochemical and thermal attributes compared to the starch-only film.

Alginate-waterborne polyurethane 3D bioprinted scaffolds for articular cartilage tissue engineering

Articular cartilage defects comprise a spectrum of diseases associated with degeneration or damage of the connective tissue present in particular joints, presenting progressive osteoarthritis if left untreated. In vitro tissue regeneration is an innovative treatment for articular cartilage injuries that is attracting not only clinical attention, but also great interest in the development of novel biomaterials, since this procedure involves the formation of a neotissue with the help of material support. In this work, functional alginate and waterborne polyurethane (WBPU) scaffolds have been developed for articular cartilage regeneration using 3D bioprinting technology. The particular properties of alginate-WBPU blends, like mechanical strength, elasticity and moistening, mimic the original cartilage tissue characteristics, being ideal for this application. To fabricate the scaffolds, mature chondrocytes were loaded into different alginate-WBPU inks with rheological properties suitable for 3D bioprinting. Bioinks with high alginate content showed better 3D printing performance, as well as structural integrity and cell viability, being most suitable for scaffolds fabrication. After 28 days of in vitro cartilage formation experiments, scaffolds containing 3.2 and 6.4 % alginate resulted in the maintenance of cell number in the range of 104 chondrocytes/scaffold in differentiated phenotypes, capable of synthesizing specialized extracellular matrix (ECM) up to 6 μg of glycosaminoglycans (GAG) and thus, showing a potential application of these scaffolds for in vitro regeneration of articular cartilage tissue.

Zein as a Basis of Recyclable Injection Moulded Materials: Effect of Formulation and Processing Conditions.

The growing concern about reducing carbon footprint has led to the progressive replacement of traditional polymeric materials by natural-based biodegradable materials. However, materials from natural sources (i.e., plants) typically possess poorer mechanical properties when compared to conventional plastics. To counterbalance this, they need to be adequately formulated and processed to eventually meet the standards for certain applications. Zein is the major storage protein from corn and can be obtained as a by-product from the corn-oil industry. It is an excellent candidate for producing green materials due to its stability, biodegradability, renewability, and suitable mechanical and technical-functional properties. In the present work, zein was blended with a plasticizer (i.e., glycerol) at three different zein/glycerol ratios (75/25, 70/30, and 65/25) and then injection moulded at three different processing temperatures (120, 150, and 190 °C). The properties of both blends and bioplastics were evaluated using dynamic mechanical analysis (DMA), tensile tests, and water absorption capacity (WUC). The properties-structure interrelation was assessed through a scanning electron microscope. Generally, a higher zein content and processing temperature led to a certain reinforcement of the samples. Moreover, all bioplastics displayed a thermoplastic behaviour finally melting at temperatures around 80 °C. The lack of massive crosslinking enabled this melting, which finally could be used to confirm the ability of zein based materials to be recycled, while maintaining their properties. The recyclability of thermoplastic zein materials widens the scope of their application, especially considering its biodegradability.

Preparation and antimicrobial properties of polymer blend based on LLDPE and polyhexamethylene guanidine

AbstractAntibacterial packaging represents an active packaging solution crafted to uphold the quality and safety of products. One of the popular polymer used in food packaging is Linear Low‐Density Polyethylene (LLDPE), due to its low cost, ease of processing, and high mechanical properties. Polymer blend based on LLDPE and antibacterial agent PHMG were prepared in the presence of PE‐g_AM compatibilizer and DCP initiator. The inclusion of PHMG resulted in a decline in the material's tensile strength. Specifically, in the sample containing 2% PHMG content, the tensile strength decreased by 11.6% in comparison to the original PE; whereas the elongation at break of the samples slightly increased. IR analysis confirmed the presence of characteristic groups of PHMG after the reaction. The polymer blend material acquired demonstrated antibacterial effects against both Gram‐negative (E. coli) and Gram‐positive (S. aureus) bacteria owing to the existence of PHMG within the material. The polymer blend sample LLDPE/2%PHMG/0.2%DCP/5%PE‐g_AM demonstrated the best antibacterial effect. The diameter of the S. aureus resistant zone reached 1.9 cm, 2.4 times bigger than the those of E. coli. The obtained properties of mechanical properties and antibacterial ability, polymer blend based on LLDPE/PHMG is suitable for application of antibacterial packaging film.

Defining the physical properties of blends of acetyl‐triacylglycerols derived from transgenic oil seeds

AbstractAcetyl‐TAG are unusually structured triacylglycerols (TAG) that possess an acetate group at their sn‐3 position. Acetyl‐TAG have different physical properties compared to regular TAG, including lower viscosity and improved cold temperature properties, making acetyl‐TAG useful for different applications, including as a diesel replacement. These unusual TAG molecules can be synthesized in the seeds of transgenic plants through the expression of diacylglycerol acetyltransferase (DAcT) enzymes isolated from different Euonymus species. In this study, the kinematic viscosity as well as the crystallization and melting behavior of blends of acetyl‐TAG and regular TAG were examined to define goals for acetyl‐TAG synthesis in transgenic plants. Even small amounts of regular TAG when blended with acetyl‐TAG had a disproportionate effect on the viscosity of mixture. This effect of regular TAG in increasing kinematic viscosity was more pronounced at lower temperatures. Under slow cooling conditions, the two different TAGs and their blends possessed two main crystallization events with different degree of separation of the thermal transition, and the lower crystallization temperature decreased with increasing amounts of acetyl‐TAG in the blend. At higher cooling rates, one broad and tailed crystallization peak was observed. Heating thermograms indicate similar polymorphic behavior of the blends and a general peak shift to lower transition range with increasing acetyl‐TAG compared to the two pure lipids. This information about the viscosity and thermal properties of blends of TAG and acetyl‐TAG will provide useful targets for engineering higher levels of acetyl‐TAG in transgenic seeds.

Influence of Silicon Additives on Tribological and Rheological Test Results for Vegetable Lubricants.

This paper describes an investigation of the effects of silicone-containing additives on the tribological and rheological properties of various lubricant blends. Aerosil® and layered silicate were used to modify lubricants containing rapeseed, linseed and soy oil that were thickened with soap thickener. Tribological tests were carried out using a four-ball concentric contact tester. On the basis of the data obtained from the tribological studies of the selected lubricant blends, it was concluded that the addition of amorphous silica increased the anti-seizure and anti-wear properties of the tested lubricants. The addition of montmorillonite caused a significant increase in the values of the individual parameters determining the level of lubricating properties of the tested lubricants in comparison with the lubricants modified with the silica additive. Based on the results of the rheological tests of the studied lubricants, it was found that the applied additives caused a change in the dynamic viscosity and chemical structure of the tested lubricants, expressed by a change in the values of the G' and G″ indices. The main finding of this manuscript was to demonstrate that the use of montmorillonite and aerosil additives improves the functional properties of vegetable-based plastic lubricants. The performance of tribological and rheological tests is of great scientific importance, as it provides an insight into the interaction of siliceous additives with the results of tribological tests on vegetable-oil-based greases. These findings make it possible to determine the behaviour of the lubricant under load and add to the knowledge of vegetable greases.

Exploring the effect of raw material properties on continuous twin-screw wet granulation manufacturability

Twin-screw wet granulation (TSWG) stands out as a promising continuous alternative to conventional batch fluid bed- and high shear wet granulation techniques. Despite its potential, the impact of raw material properties on TSWG processability remains inadequately explored. Furthermore, the absence of supportive models for TSWG process development with new active pharmaceutical ingredients (APIs) adds to the challenge. This study tackles these gaps by introducing four partial least squares (PLS) models that approximate both the applicable liquid-to-solid (L/S) ratio range and resulting granule attributes (i.e., granule size and friability) based on initial material properties. The first two PLS models link the lowest and highest applicable L/S ratio for TSWG, respectively, with the formulation blend properties. The third and fourth PLS models predict the granule size and friability, respectively, from the starting API properties and applied L/S ratio for twin-screw wet granulation. By analysing the developed PLS models, water-related material properties (e.g., solubility, wettability, dissolution rate), as well as density and flow-related properties (e.g., flow function coefficient), were found to be impacting the TSWG processability. In addition, the applicability of the developed PLS models was evaluated by using them to propose suitable L/S ratio ranges (i.e., resulting in granules with the desired properties) for three new APIs and related formulations followed by an experimental validation thereof. Overall, this study helped to better understand the effect of raw material properties upon TSWG processability. Moreover, the developed PLS models can be used to propose suitable TSWG process settings for new APIs and hence reduce the experimental effort during process development.

Quality evaluation of flour blends and biscuits produced from breadfruit and lima bean flours

This study investigated the nutritional composition and physicochemical properties of breadfruit based flour blends as a way of showcasing its potential as an alternative intermediate food material in the production of some foods on the diet list of developing countries. Breadfruit was processed into flour and its flour was substituted with lima bean flour (0 – 40%). Proximate and amino acid composition, functional and pasting properties of the flour blends were determined using standard methods. Antioxidant activity, physical properties and sensory acceptability of biscuits produced from the flour blends were also evaluated using standard methods. Wheat biscuit served as control. The results revealed that protein ranged from 6.67 to 9.14%, fat 0.54 – 1.51%, ash 1.85 – 3.07%, crude fibre 4.62 – 4.98% and carbohydrate 68.23 – 80.58%. All essential amino acids were present in the flour blends constituting 34.86 -40.03% of the total amino acid present. There were significant variations in the functional and pasting properties. Biscuits produced from the flour blends exhibited appreciable radical scavenging ability and reducing power; DPPH values were 9.67 – 78.01%, ABTS 0.016 – 0.0216 mM/g and FRAP 1.03 – 14.56 mg/g. Biscuit produced from breadfruit flour with inclusion of 20% lima bean flour showed comparable overall acceptability with the control.

PREPARATION AND EVALUATION OF PROPRANOLOL HCL AND CARBAMAZEPINE RELEASE PROFILES FROM POLY(Є-CAPROLACTONE) MICROPARTICLE BLENDS SYSTEM

Objective: The goal of this research was to look into the physicochemical properties of poly(-caprolactone) microparticle blends that contained medicines of various solubilities (Propranolol HCl [Pro] and carbamazepine [CBZ]). Methods: W/O/W emulsion for Pro and O/W emulsion for CBZ were used to create microparticle blends. With dispersion time intervals (DTI) of 0 and 60 min, the Pro emulsion (W/O) and CBZ oil phase (O) were dispersed in an external aqueous phase (W). Scanning electron microscopy was used to examine the morphology of microparticle blends (SEM). Focused beam reflectance measurements were utilized to monitor the particle size mean of emulsion droplets/hardened microparticles (FBRM). In phosphate buffer (pH 7.4), encapsulation efficiency (EE) and in vitro drug release were also examined. Results: The final microparticle blends generated by solvent evaporation method were spherical and had two populations, according to the findings. The size of microparticle blends prepared with DTI 60 min and stirring duration 4 h was bigger than those prepared with DTI 0 min, according to FBRM data. In microparticle blends, encapsulation efficiency ranged from 62.05±3.74 percent to 66.38±4.16 percent for Pro and 70.56±4.62 percent to 73.85±4.11 percent for CBZ. After 28 d, drug release in phosphate buffer revealed that Pro release (33%) was shorter than CBZ release (60%) from microparticle blends with DTI 60 min. This was related to the interaction of the oil phase (CBZ) with hard particles from the primary emulsion (Pro), in which the oil phase occluded and covered surface structure of the harsh particles from the primary emulsion. Conclusion: Novel microparticle blends comprising drugs/medicines with varying solubilities (e. g. propranolol HCl and carbamazepine) have a lot of promise as controlled-release drug delivery systems. The physical properties of microparticle blends were impacted by the type of dispersion time interval used.

Intelligent Modelling of the Real Dynamic Viscosity of Rubber Blends Using Parallel Computing.

Modelling the flow properties of rubber blends makes it possible to predict their rheological behaviour during the processing and production of rubber-based products. As the nonlinear nature of such complex processes complicates the creation of exact analytical models, it is appropriate to use artificial intelligence tools in this modelling. The present study was implemented to develop a highly efficient artificial neural network model, optimised using a novel training algorithm with fast parallel computing to predict the results of rheological tests of rubber blends performed under different conditions. A series of 120 real dynamic viscosity-time curves, acquired by a rubber process analyser for styrene-butadiene rubber blends with varying carbon black contents vulcanised at different temperatures, were analysed using a Generalised Regression Neural Network. The model was optimised by limiting the fitting error of the training dataset to a pre-specified value of less than 1%. All repeated calculations were made via parallel computing with multiple computer cores, which significantly reduces the total computation time. An excellent agreement between the predicted and measured generalisation data was found, with an error of less than 4.7%, confirming the high generalisation performance of the newly developed model.

Effect of Incorporation of Graphene Nanoplatelets on Physicochemical, Thermal, Rheological, and Mechanical Properties of Biobased and Biodegradable Blends.

This work aimed to study the effect of the incorporation of graphene nanoplatelets (GRA 0.5% and 1% (w/w)) on the matrices of biobased polymers composed of starch-based materials (B20) and poly(butylene succinate) (PBS) using pine rosin (RES) as a compatibilizer. Three formulations were produced (B20/RES/PBS, B20/RES/PBS/GRA0.5%, and B20/RES/PBS/GRA1%), and their mechanical properties (tensile, flexural, hardness, and impact), rheological behavior, thermal properties (thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC)), chemical analysis (Fourier transform infrared-attenuated total reflectance (FTIR-ATR) spectroscopy), and contact angle were evaluated. Hardness (Shore D), tensile, and flexural moduli increased, whereas elongation at break and toughness decreased as GRA content increased. FTIR studies strongly supported the existence of interactions between polymeric matrices and the large surface area of GRA. The viscosity flow curves were well fitted to the Cross-Williams-Landel-Ferry (Cross-WLF) model, and the three formulations exhibited non-Newtonian (shear-thinning) behavior. The analysis of water contact angles indicated that the formulation surfaces have hydrophilic behavior. All the samples are thermally stable, and the results of this study can be used to optimize the application of biobased graphene-based composites for applications in injection molding industries.
