A simple and efficient Pd/Al2O3-NR-RD catalyst was prepared by depositing palladium on a shape controllable Al2O3-NR support through a two-step process that involves hydrothermal synthesis of Al2O3-NRs followed by reductive-deposition of palladium. This catalyst showed high activity in the catalytic formylation of amines by CO2-H2 under mild conditions with up to 96% yield.

Under proper conditions, small particles may be suspended in a regularly-spaced array called a Coulomb crystal. In this paper we discuss the application of this phenomenon to the self-assembly of nanoparticles in a lattice-lie array on a substrate. Issues associated with depositing the particles, and the size and lattice spacing of the particles are discussed.

A finite-difference time-domain (FDTD) numerical analysis is used to demonstrate that a toroidal solenoid, coaxial with an electric dipole, is a remarkable nonradiating configuration. It can be used to measure the dielectric permittivity of any ambient matter. It becomes a directional radiator at an interface between two dielectric media, depositing energy in the material with the highest polar...

Unusual antifogging antireflective thin films with a maximum transmittance of 98.9% have been realized surprisingly by depositing a hollow silica nanoparticle layer on top of an antifogging polymer layer, which was considered as an irrational design according to the previous knowledge.

A composite zeolite adsorbent was prepared by conformally depositing an ultrathin porous TiO2 coating on the external surface of the 5A zeolite by molecular layer deposition (MLD) and subsequent calcination. The composite adsorbent showed significantly improved ideal adsorption selectivity for CO2-CH4, CO2-N2 and propylene-propane.

Conditions for depositing perovskite-oriented Pb0.92Sr0.08(Zr0.65Ti0.35) O3 thin films on gold by RF magnetron sputtering are investigated. Deposition results were analysed by scanning electron microscopy, X-ray photoelectron spectroscopy and X-ray diffractometry. It was found that the desired perovskite phase can be obtained at a substrate temperature of 300 C, much lower than the typically re...
