The popularity of jute-based bio and hybrid composites is mainly due to an increase in environmental concerns pollution. Jute fibers have low cost, high abundance, reasonable mechanical properties. Research all-natural increased exponentially the environment hazards synthetic fibers-based composites. based been extensively used number applications. Hybrid enhanced physical properties, reasonably better than jute fiber A detailed analysis was carried out this review. primary aim review paper...
Multiple machine learning models were developed in this study to optimize biodiesel production from waste cooking oil a heterogenous catalytic reaction mode. Several input parameters considered for the model including temperature, time, catalyst loading, methanol/oil molar ratio, whereas percent of yield was only output. Three ensemble utilized study: Boosted Linear Regression, Multi-layer Perceptron, and Forest Randomized Tree optimization yield. We then found their optimized configurations...
Abstract The demand for bio-medical implants has significantly increased to treat different medical conditions and complications. latest research in material science is paving the path new generation of biomedical that mimic natural bone tissues enhanced biocompatibility. A implant must be bio-compatible, non-toxic bioactive. main reasons implantation are ageing, overweight, accidents genetic diseases such as arthritis or joint pain. Diseases osteoporosis osteoarthritis can severely damage...
This study aimed to investigate the application of radial basis function (RBF) and multilayer perceptron (MLP) artificial neural networks for modeling hydrogen production by co-gasification rubber plastic wastes. Both RBF MLP were configured determining best-hidden neurons that could offer optimized performance. Based on neurons, a model architecture 4-16-1, 4-20-1, 4-17-1, 4-3-1 was obtained (with standard activation function), ordinary one-layer MLP, two-layer respectively, indicating...
There is a growing attention to the bio and renewable energies due fast depletion of fossil fuels as well global warming problem. Here, we developed modeling simulation method by means artificial intelligence (AI) for prediction bioenergy production from vegetable bean oil. AI methods are known complex nonlinear process. Three distinct Adaptive Boosted models including Huber regression, LASSO, Support Vector Regression (SVR) neural network (ANN) were applied in this study predict actual...
A crystalline and conjugated semiconductor thin film of poly(o‐phenylene diamine‐co‐m‐phenylene diamine) copolymer [PoPmP] TF with a thickness 150 ± 3 nm is fabricated by physical vapor deposition technique (PVD). The produced in an acidic solution using oxidative polymerization method. ratio between the monomers initiator 1:1:2. characterization obtained powder carried out different techniques includes Fourier‐transform infrared spectroscopy (FTIR), UV–Vis (UV–Vis), proton nuclear magnetic...
In this study, a facile, environmentally friendly, room-temperature synthesis of Ag-coated on microporous TiO2-based catalysts and their application as photocatalyst to degradation penicillin an antibiotic from pharmaceutical wastewater was investigated. The sol-gel method used for the preparation SiO2 SiO2@TiO2. Then, SiO2@TiO2 wrinkled using hydrothermal treatment. Finally, Ag plasmonic material doped via wet chemistry approach. synthesised photocatalysts were characterized different...
Polyurethane (PU) paint with a hydrophobic surface can be easily fouled. In this study, hydrophilic silica nanoparticles and silane were used to modify the hydrophobicity that affects fouling properties of PU paint. Blending followed by modification only resulted in slight change morphology water contact angle. However, test using kaolinite slurry containing dye showed discouraging results when perfluorooctyltriethoxy was coating blended silica. The fouled area increased 98.80%, compared...
This paper evaluates the damage evolution process under extremely low-cycle fatigue (ELCF). The study explores behavior different stress states. influence of multiaxial state on metal’s life is determined. Two states were examined: (a) axisymmetric and (b) plane-strain. based modified Mohr–Coulomb (MMC) ductile fracture criterion that was extended to cover ELCF regime in a previous research study. Four distinctive geometries are designed effect evolution. model calibrated for prediction...
Pyrolysis of anaerobically digested sludge can serve as an efficient biomass for biofuel production. produces products like char, bio-oil, and combustible gases by thermochemical conversion process. It be used treatment that decreases disposal problems. Sludge produced from anaerobic co-digestion (microalgae, cow dung, paper) waste has high carbon hydrogen content. We investigated the candidacy having heating value (HHV) 20.53 MJ/kg a reliable biofuels The process pyrolysis was optimized...
Anaerobic co-digestion (AcoD) has been practiced for decades to convert waste into value-added energy products, especially biogas. This study aimed assess the potential of biogenic methane (CH4) production from pretreated cotton gin trash (CGT), cow manure, and sludge. CGT contains high cellulosic content, making it a reliable feedstock production. To further improve biogas quantity quality, was subjected physical pretreatments, i.e., hot water (HW), ultra-sonication (US), combination both...
Separation and capture of CO2 from gas mixtures is great importance environmental point view which can be effectively achieved using amino acids as new class chemical absorbents. However, screening the proper absorbent with desired separation properties experimental measurements tedious costly. The predictive computational techniques employed to overcome this problem. In study, for estimating analyzing solubility in solvents based on acid salt solutions, we created two regression models...
Abstract The present research investigates the effects of various concentrations single-walled carbon nanotubes (SWCNTs) on viscoelastic and thermomechanical characteristics styrene-butadiene/ethylene propylene diene polymer (SBR/EPDM) blended polymeric matrices (60:40). Standard elastomeric methods are used to synthesise SWCNTs-reinforced EPDM/SBR nanocomposite blends. results reveal that high SWCNTs offer remarkable thermal stability enhancement. reinforced with 0.6 mass% become 20%...
