In this paper, the nucleation behavior of glutaric acid (GA) in solvents with different hydrogen-bond donating (HBD) capabilities was studied using a metastable zone width (MSZW) experiment and modified Sangwal's theory. Through designing cooling rates, saturation temperatures, HBD capabilities, it is demonstrated that MSZWs increase when increasing rate or decreasing temperature capability. Interestingly, under framework classical theory, we find critical nuclei size Gibbs free energy do...
The effect of the porosity change cathode gas diffusion layer (GDL) along cell length on proton exchange membrane fuel (PEMFC) is evaluated using calculation model and numerical method. A detailed analysis polarization curve, temperature distribution center surface, material, current law carried out for six different models. It found that influence GDL curve increases with increase in density, reaches maximum at limit density. directly proportional to porosity, has limited it. existence...
Inspired by the concept of multicomponent reactions, a novel one-pot reaction involving heterocyclic ketene aminals (HKAs), Meldrum’s acid and aldehydes has been developed employed for construction small library tetrahydropyridinone-fused 1,3-diazaheterocycles.
Abstract Yttrium aluminosilicate glass with high alkali metal oxides content provides an excellent foundation for ion exchange to achieve high‐strength preparation. Nevertheless, poor acid resistance limits its application under extreme acidic conditions. This study investigates the effects of Al 2 O 3 /SiO ratios on structure, resistance, thermal, and mechanical properties glass. Experimental results reveal that Vickers hardness, elastic modulus, transition temperature, expansion softening...
When the proton exchange membrane fuel cell is used as a power source device to operate in low temperature environment, will have series of problems such difficulty starting due overall temperature, reduced output performance, and life. External heating agent one important methods solve above problems. In this paper, based on most commonly rectangular DC channel model, numerical simulation method analyze effect different agents continuous performance at an ambient 253.15 K. By analyzing...
The influence of a tubular structure PEMFC (proton exchange membrane fuel cell) with different flow patterns is investigated in this study. A complete 3D non-isothermal model constructed for square and circular PEMFCs, the distribution oxygen water concentration cathode channels, current density, power density cell net are studied. To end, four arrangements chordal (SC), peripheral (SP), (CC) (CP). calculation effective area boundary conditions remains same when performing all...
Abstract Topological constraint theory (TCT) and molecular dynamics simulations (MD) are utilized to study the effect of Y 2 O 3 /SiO substitution on short‐ medium‐range structures properties in aluminosilicate glasses containing . Experimental methods have been applied characterize as‐prepared verify accuracy MD simulations. It was found that Y–O bond distance is around 2.38 Å average coordination number 5.78. The introduction disrupts Si–O Al–O bonds network structure elevates proportion...
A novel red-emitting phosphor, CaYAl3O7: Eu3+, Sm3+, is synthesized by a combustion method at low temperature (850°), and the single phase of CaYAl3O7 confirmed powder X-ray diffraction measurements. The photoluminescence property results reveal that red emission intensity Eu3+ strongly dependent on Sm3+ concentration. Only luminescence detected in Eu3+-Sm3+ co-doped phosphor with 393 nm excitation. However, under characteristic excitation (402 nm) not only but also are observed. possible...
A combination of X-ray photoelectron/Auger electron spectroscopy and soft emission has been employed to investigate the impact different alkali postdeposition treatments (PDTs) on chemical structure (buried) CdS/Cu(In,Ga)Se2 heterojunction: key interface in chalcopyrite-based thin-film solar cells. Chemical bath deposited (CBD) CdS layers thicknesses NaF PDT (CIGSeNaF) + KF (CIGSeNaF+KF) Cu(In,Ga)Se2 absorbers prepared at low temperature (to facilitate use flexible, e.g., polyimide,...
