Abstract The diffusion coefficient at zero penetrant concentration D 0 of dichloromethane, chloroform, carbon tetrachloride, cyclohexane, benzene, o‐xylene, m ‐xylene, and p n ‐hexane in LDPE were measured 25°C, using the desorption method. values obtained this way are correlated with size, shape, chemical nature molecules. temperature dependence coefficients toluene also reported limited range 25–45°C. It indicates that, spite a size larger than that toluene, has lower activation energy diffusion.
Bentonite clay is an abundant and low-cost adsorbent silk fibroin, a naturally occurring protein, both have low capacity to remove lethal heavy metal ions from aqueous solution separately. To enhance their adsorbing capacity, new fibroin-based bentonite composite was prepared for improving water quality by eliminating i.e., lead, cadmium, mercury, chromium. The as-synthesized shows better sorption than either of them alone. analyze structural properties characteristic functional groups,...
Synthesis, electrochemical behavior, burning rate catalytic performance, and migration mechanism of ferrocene-based polyethyleneimines.
This study investigates the phenomena of fluid flows, general heat transfer and entropy generation on transient natural convection in a square cavity occupied with saturated non-Darcy porous medium dissipation effects thermal radiation. The governing equations for flows transfer, corresponding boundary initial conditions system are solved use alternate direct implicit method (ADI). impact dimensionless parameters flow effect including generation, structure interaction cases discussed....
Burning rate catalysts are of great importance in solid composite propellants for their unique property accelerating combustion speed. Among various kinds burning catalysts, ferrocene and its derivatives exhibit excellent catalytic effects have become the most widely used catalysts. However, these simple ferrocenyl compounds trend to migrate during storage, which causes damage propellants, equipment environment can even affect personal safety. The exploration novel anti‐migratory...
COVID-19 is a transmissible and infectious disease with symptoms similar to pneumonia, ranging from moderate severe. This study investigated the psychological experiences of patients both during their illness after recovery. The employed purposive sampling semi-structured interviews gather insights 13 survivors (7 women 6 men). Interpretive Phenomenological Analysis was used analyze interview transcripts. Participants ranged in age 22 62 years. analysis identified seven main themes illness,...
This research utilized SCAPS-1D simulation software to model a high-efficiency CIGS-based solar cell with configuration Ag/ZnO:Al/i-ZnO/CdS/CIGS/Mo. Various optimizations were performed, focusing on the absorber layer’s thickness, acceptor density, and defect density enhance cell’s performance. Furthermore, work function values of rear contact metals analyzed understand their influence critical photovoltaic parameters like open-circuit voltage (Voc), short-circuit current (Jsc), fill factor...
Infected non-union of the tibia remains a significant clinical challenge due to bone’s subcutaneous location and high risk complications such as delayed healing infection. The Ilizarov external fixator is increasingly recognized an effective method for managing cases, offering biomechanical stability facilitating bone regeneration. Objective: To evaluate outcomes fixation in treating infected tibial non-unions, focusing on healing, functional results, complications. Methods: A retrospective...
One of the most important components solid rocket propellant is burning rate catalysts (BRC) which enhance composite propellant. Low‐pressure exponents and stable are key features an excellent Addition BRC to results in increase decrease pressure exponents. Among all BRC, ferrocene‐based have attracted much attention because their better microscopic homogeneities distribution, ignitability propellants good compatibility with organic binder. However, main barrier for development practical...
In this study, we investigated buoyancy-induced convection in a permeable square hollow containing four embedded cylinders and subjected to magnetic field using numerical methods. The finite element approach was used solve the governing equations of system as well initial boundary conditions. We analyzed effects emerging non-dimensional quantities on flow pattern thermal field, entropy production, relation thermophysical properties obstacles. limiting case, compared our results with already...
To overcome migration problems of ferrocene‐based burning rate catalysts and to enhance ammonium perchlorate (AP)‐based propellants, eleven compounds ( 1 – 11 ) were synthesized by the condensation reaction ferrocenecarbonyl chloride with corresponding amines alcohols. The synthesis was confirmed using H NMR, Fourier transform infrared UV–visible spectroscopy. Their electrochemical properties analyzed cyclic voltammetry. showed redox behavior due presence ferrocene. catalytic in thermal...
Abstract The diffusion coefficients at zero penetrant concentration, D 0 , of n ‐heptane, ‐octane, ‐decane, and 2,2,4‐trimethylpentane (TMP) in LDPE were obtained the range 25–50°C, using desorption method. dependence on size shape is reported. It was found that decreases with increasing molecule size. activation energies temperature 25–50°C increase are independent temperature. results interpreted terms free volume theory semiquantitative estimates parameters
This paper focus on natural convection in the presence of an applied magnetic field for analysing entropy generation and fluid flow phenomena a porous medium. The numerical technique adopted was finite difference method. parameters used numerically flows are Rayleigh number (103 ≤ Ra 106), Eckert (10−6,10−5,5 × 10−5) , Forchheimer (0 Γ 1), inverse Darcy γ radiation Rd 10), Prandtl (Pr = 0.7,1.0,7.0,10) Hartmann Ha 30). results were compared with existing papers excellent agreements have been...
This study presents the production of FAMEs from non-edible Silybum marianum oil using a catalyst consisting an MXene/SrTiO3 composite.
