A series of Fe-based catalysts with accurately controlled amounts Na are synthesized to investigate the relationship between promoter and catalytic performance for CO2 hydrogenation alkenes. With increasing amount Na, both conversion alkenes selectivity increase at low moderate then plateau (with highest be 36.8% 64.3%, respectively), while corresponding methane production decreases 7.2%. It is found that addition enhances adsorption CO2, facilitates formation stability active species Fe5C2,...
Addition of Mn to Na/Fe catalysts enhanced light olefin selectivity in CO<sub>2</sub> hydrogenation through modulation the C–C coupling reaction.
Molecular dynamics (MD) simulation was conducted for a ε-CL-20 (2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexazisowurtzitane) crystal, β-HMX (1,3,5,7-tetranitro-1,3,5,7-tetrazocane) ε-CL-20/HMX cocrystal and its composite with the same molar ratio as in using COMPASS force field NPT ensemble at different temperatures. The maximum bond length (Lmax) of N–NO2 trigger bond, cohesive energy density (CED) binding (Ebind) between HMX CL-20 molecules well elastic properties were calculated. Lmax...
The synthesis of ruthenium nanoclusters (NCs) is crucially important but challenging for hydrogen production. By taking advantage confinement effect nanopores in 3D porous carbon and urea as nitrogen source, we developed a straightforward method preparation uniform Ru NCs simultaneous nitriding the scaffolds (Ru/3DNPC). resulting Ru/3DNPC-500 had measured overpotential 15 mV at 10 mA cm–2 toward evolution reaction well very high turnover frequency (584 mol H2 (mol min)−1) hydrolytic...
Magnetic recyclable Pt<sub>y</sub>Co<sub>1−y</sub>/Ti<sub>3</sub>C<sub>2</sub>X<sub>2</sub> (X = O, F) catalyst exhibits excellent catalytic performance for the hydrolysis of AB at room temperature.
The 2200 MPa low-alloy ultra-high-strength steels microalloyed with Ti (Ti-steel) and Nb (TiNb-steel) were quenched at 860 °C tempered 180 °C, the mechanical properties, microstructure, precipitated phase studied by SEM, TEM, physicochemical analysis. results of properties showed that TiNb-steel had higher strength than Ti-steel, a yield 1746 1802 tensile 2198 2232 MPa, respectively. finer structure effective grain sizes being 0.86 μm 1 μm, more MC-type carbides carbide contents 0.24 wt.%...
This study explores the factors influencing mentoring relationships in Malaysian higher education institutions (HEIs) from both mentors' and mentees' perspectives. Using a qualitative single case study, data were collected 12 participants—six experienced mentors six new academic staff—through semi-structured interviews. Thematic analysis revealed four key themes: informal mentorship dynamics, emotional bonding, affective encouragement, an integrated collegial environment. Findings highlight...
Cadmium sulphide (CdS) quantum dots (QDs), sensitizing hierarchical bismuth oxychloride (BiOCl) photocatalysts, were synthesized via a facile solvothermal approach and characterized in detail. The as-prepared CdS–BiOCl photocatalyst possessed an extended light absorption range efficient charge separation properties simultaneously compared with pure BiOCl, especially the visible region. results revealed that newly formed oxygen vacancies will play important role degradation process, which...
A practical Ag-catalyzed formal decarboxylation and radical difluoroalkylation–carbocyclization–hydrolysis route is established to construct a series of structurally diverse CF 2 -containing N-heterocycles.
Considerable hydrogen production from ammonia borane hydrolysis was achieved by Pt@cobalt oxide/N,O-rich carbon under ultrasonic irradiation in basic solution.
This study focuses on the safe evacuation strategy and process in subway train under fires. The station mode should be adopted if power system of a is normal fire. While, tunnel fails because effects Under mode, direction smoke opposite to that most passengers, passengers evacuated toward fresh wind. By using numerical simulation software Pathfinder PyroSim, passenger time different conditions calculated, safety evaluated. results show obviously shorter than mode. With same conditions, 2193...
The effect of conditioner aggressiveness is investigated in interlayer dielectric polishing on three types pad. A method using confocal microscopy used to analyze the pad–wafer contact. Results show that a more aggressive produces higher rate while at same time pad surface with fewer contacting summits and less contact area. It found ratio summit density area fraction important than either parameter measured separately since determines mean real pressure. Modeling results based measurements...
In this study, an optical method using laser confocal microscopy was developed to measure the surface contact area and topography of pads under a dry static condition. A custom-made pad sample holder with sapphire window miniature load cell used collect images at controlled loads. By extracting black spots in collected images, summit density were obtained. The analysis post polishing (8,289×921 µm 2 ) showed that increased from 0.026 0.045% when pressure 4 psi further 0.059% 6 psi. also...
Both contact and non-contact methods are used to analyze surface properties of three types chemical mechanical planarization (CMP) pads: plain, X Y grooved, concentrically grooved. Optical interferometry is probe the pad without produce a height probability density function (PDF). The right hand contacting tail PDF often found be exponential for CMP pads decay length (λ) as measure abruptness can extracted. An incremental loading device developed response. A pad–wafer model based on...
