Pd/zeolite passive NOx adsorber (PNA) materials were prepared with solution ion-exchange between NH4/zeolites (Beta, ZSM-5, and SSZ-13) PdCl2 solutions. The nature of Pd (dispersion, distribution, oxidation states) in these was characterized Na+ ion exchange, TEM imaging, CO titration FTIR, situ XPS. trapping release properties tested using feeds different compositions. It is concluded that multiple species coexist materials: atomically dispersed the cationic sites zeolites PdO2 PdO...
Inspired by the structural organization of mitochondria and bioadhesive principle, a simple versatile approach to construct multienzyme system is developed. More specifically, composed polydopamine (PDA) microcapsule scaffold three spatially separated enzymes. The PDA microcapsules are prepared through rapid, spontaneous self-polymerization dopamine on surface CaCO3 microparticle template, followed dissolution template using EDTA. wall thickness can be tuned concentration in an aqueous...
Using a traditional aqueous solution ion exchange method under protecting atmosphere of N2, series Fe/SSZ-13 catalysts with various Fe loadings were synthesized. UV–vis, EPR, and Mössbauer spectroscopic methods, coupled temperature-programmed reduction desorption techniques, used to probe the nature sites. The major species are extraframework Fe(III) species: [Fe(OH)2]+ (monomeric) [HO–Fe–O–Fe–OH]2+ (dimeric). Larger oligomers unknown nuclearity, poorly crystallized oxide particles, together...
Experiments and density functional theory (DFT) models are combined to develop a unified, quantitative model of the mechanism kinetics fast selective catalytic reduction (SCR) NO/NO2 mixtures over H-SSZ-13 zeolite. Rates, rate orders, apparent activation energies collected under differential conditions reveal two distinct kinetic regimes. First-principles thermodynamics simulations used determine relative coverages free Brønsted sites, chemisorbed NH4+, physisorbed NH3 as function reaction...
A novel approach combining biomimetic mineralization and bioadhesion is proposed to prepare robust versatile organic−inorganic hybrid microcapsules. More specifically, these microcapsules are fabricated by sequential deposition of inorganic layer organic on the surface CaCO3 microparticles, followed dissolution microparticles using EDTA. During preparation process, protamine induces hydrolysis condensation titania or silica precursor form biomineral layer. The bioadhesive was formed through...
A total of 479 bacterial strains were isolated from brine (Bohai, Qinhuangdao City, Hebei Province, China). Bioassay results indicated that 4 named Ha1, Ha17, Ha38, and Ha384 had herbicidal activity. And strain Ha1 the highest effective As a result, this study aims to identify characterize its physiological biological activities, evaluate activity metabolites, develop 'pesta' formulation assess effectiveness on Digitaria sanguinalis. was identified as Serratia marcescens based 16S rDNA...
The introduction of DPA units into a PECD copolymer has an amphoteric effect on the hydrolysis behavior CBAs under acidic conditions.
Interface thermal conductive material for superconducting magnet cryostat is important cryogenic cooling path. Calculation and simulation with optimized boundary condition parameter setting conducted to approach practical application a method developed. Mechanical function heating transmission are mainly considered in this paper. Several key steps will be executed: Stress distribution analysis, interface stress-strain distribution, contact area, heat transfer model, conductivity, radiation,...
Fe–Co–Ni–Mn films doped with different concentrations of Ge were prepared on the Si substrates by using radio frequency magnetron sputtering. Transmission electron microscopy (with an energy dispersive x-ray spectrometer) and diffractometer used to systematically study microstructure evolution Fe–Co–Ni–Mn–Ge films. The results indicate that a large amount show significant element segregation after rapid high-temperature annealing. However, decrease in doping approximately equal molar ratio...
This study addresses the escalating issue of atmospheric CO2 emissions and climate change, exacerbated by increased use fossil fuels. It explores synthesis low-carbon alcohols as a viable method to utilize excess CO2, meeting growing demand for sustainable fuel alternatives. The research focuses on challenges activating often requiring conversion CO via reverse water gas shift reaction (RWGS) prior alcohol synthesis. Through detailed case studies, this review investigates factors influencing...
