The electronic structures and field emission properties of hybrid graphene-ZnO are investigated by density functional theory. binding energies, energy levels, the corresponding local electron distributions neutral charged in electric fields analyzed, which show that modified significantly applied fields. reduction gaps change states vicinity Fermi level observed. work functions decrease linearly with increasing fields, indicate enhancement properties. In addition, ionization potentials...
A beaded ZnO nanocluster as a novel stand-alone system has been introduced by interconnecting different numbers of highly stable (ZnO)12 basic units. Geometries, stabilities, electronic properties, and vibrational spectra the nanoclusters have systematically studied using density functional theory. The results indicate that with large binding energies high stabilities during their growth process. energy gaps (ZnO)12×n (n ≥ 3) show relatively slow decrease, indicating are insensitive to...
The adsorption, tautomerization, and hydrogenation of acetone on Pt(111) surfaces were investigated by using density function theory calculations. role the keto–enol isomerization selective unselective decomposition was also studied. results revealed that only a small amount adsorbed could undergo enolization subsequently decompose clean surface at moderate condition. enol tautomer is origin surface. effect under sufficient hydrogen pressure not significant. These suggested enhance
The goal of this paper is to reconstruct spatially distributed dielectric constants from complex-valued scattered wave field by solving a 3D coefficient inverse problem for the Helmholtz equation at multi-frequencies. data are generated only single direction incident plane wave. To solve problem, globally convergent algorithm analytically developed. We prove that provides good approximation exact without any priori knowledge point in small neighborhood coefficient. This main advantage our...
The intrinsic kinetic of the liquid-phase dehydrogenation isopropanol over an amorphous Raney nickel catalyst was determined to be in temperature range 348 355 K. model based on Langmuir–Hinshelwood mechanism adopted for experimental data fitting. An isopropanol–acetone–hydrogen chemical heat pump (IAH–CHP) with a reactive distillation column proposed this paper. A mathematical established evaluate energy performance IAH–CHP terms coefficient (COP) and exergy efficiency, which obtained...
Abstract A series of novel ionic liquids comprising crown-ether functionalities in cations or anions (crowned liquids) have been prepared and characterized.
The synthesis of noble metal nanoparticles (NMNPs) using, or in the presence of, ionic liquids (ILs) represents a burgeoning direction materials chemistry. Processing these nanomaterials synthesized ILs would be drastically simplified if they could routinely dispersed into wide variety polar/nonpolar solvents. We herein demonstrate phase transfer as-prepared from to an organic aqueous medium. protocol involves first mixing sols and ethanolic methanolic solution agent then extracting...
Effective capture and recycling of SO2 are great significance to environmental protection high-value utilization. Herein, a promising strategy for effective reversible was proposed using alkaline ternary deep eutectic solvents (DESs) as absorbents. The absorbents consisting choline chloride (ChCl), diethylenetriamine (DETA), ethylene glycol (EG) with different molar ratios show relatively lower viscosity higher thermal stability. Here, ChCl/DETA/EG (1:1:2) could take out 0.87 g SO2/g solvent...
Recently, Cristofaro-Gardiner and Hutchings proved that there exist at least two closed characteristics on every compact star-shaped hypersuface in ${\bf R}^4$. Then Ginzburg, Hein, Hryniewicz, Macarini gave this result a second proof. In paper, we give it third proof by using index iteration theory, resonance identities of remarkable theorem Ginzburg et al.
The optical fiber probe has been for the first time applied to investigate hydrodynamics and gas‐phase distribution at high gas/liquid ratios in a two‐phase flow monolith bed with 0.048 m diameter 400 cpsi. Local hydrodynamic parameters including gas holdup, bubble frequency, velocity, length single channels were measured by 16 inserted single‐point probes within under nozzle as liquid distributor. following findings are reported. (1) can be used an efficient convenient technique measuring...
