Mesoporous carbon materials with controlled pore and wall structures have promising applications in energy storage. In this work, we prepare a series of ordered mesoporous carbons (OMCs) by adjusting the pyrolysis temperature via a soft templating and catalytic graphitization approach. The structure of graphitic tubul…
Simultaneous removal of low concentration formaldehyde (HCHO) and ozone byproduct was investigated in the gaseous VUV (vacuum ultraviolet) photocatalysis by using noble metal modified TiO 2 films. Noble metal (Pt, Au, or Pd) nanoparticles were deposited on TiO 2 films with ultrafine particle size and uniform distribut…
We investigate the properties of freely suspended nematic nanodroplets of increasing size formed by elongated Gay–Berne mesogens, using extensive molecular dynamics simulations. We find that the nanodroplets have an elongated shape with an aspect ratio changing with size and that in the 50–100 nm size range (N ≈ 50 00…
Graphene oxide‐gold composites were prepared by one‐step reaction in aqueous solution, where the gold nanoparticles were deposited on the graphene oxide during their synthesis process. Transmission electron morphology, X‐ray diffraction, Roman spectra, and UV‐Vis absorption spectra were used to characterize the obtain…
We present here the micropatterns of layer-by-layer (LbL) assembled soft films generated using microfluidic platform that can be exploited for selective cell growth. Using this method, the issue of cell adhesion and spreading on soft LbL-derived films, and simultaneous utilisation of such unmodified soft films to expl…
Polystyrene/graphene (PS/GP) core-shell microspheres which are demonstrated to be highly sensitive for dopamine (DA) detection with excellent morphology were prepared via electrostatic interactions and π-π accumulation. This interesting discovery is practical to utilise compared to traditional biotechniques and surfac…
Pre-synthesized ruthenium dioxide nanoparticulates (RuO(2) NPs) with low level of aggregation were well dispersed in mesoporous silica SBA-15. As a catalyst for water oxidation, the supported RuO(2) NPs exhibit excellent catalytic activity and recyclability. The initial turnover frequency (TOF) is to date the highest…
Various molecular magnetic compounds whose magnetic properties can be controlled by external stimuli have been developed, including electrochemically, photochemically, and chemically tunable bulk magnets as well as a phototunable antiferromagnetic phase of single chain magnet. In addition, we present tunable paramagne…
An amorphous MnO(2)·nH(2)O/microporous carbon spheres (α-MnO(2)·nH(2)O/MCS) composite electrode material is prepared by a chemical co-precipitation method. It is observed that the amorphous MnO(2) particles are deposited on the surface of the MCS, which form a network with a uniquely developed three-dimensional open p…
The dissolution of ceria is studied through a catalytic reduction process involving platinum nanoparticles in mild conditions at near ambient temperature. The deposition of platinum nanoparticles is made by sonication (Ar, 18 W cm−2, 20 kHz), and further dissolution is studied as a function of different parameters suc…
Biphasic solid state composites of the type metal/metal oxide or element/element oxide can be synthesized in one pot chemical reactions using so called molecular "single source precursors". Due to their singular genesis these composites show peculiar hetero-structures based on core-shell hierarchies such as superlatti…
Precisely-controlled fabrication of single ZnO nanoemitter arrays and their possible application in low energy parallel electron beam exposure are reported. A well defined polymethyl methacrylate (PMMA) nanohole template was employed for local solution-phase growth of single ZnO nanoemitter arrays. Chlorine plasma etc…
The long term performance of SOFC with nanocomposite Ni-YSZ anode and LSM-YSZ cathode was reported.The SOFC was prepared by infiltrating polymeric precursors of NiO and LSM from anode and cathode sides respectively.The fuel cell showed relatively high initial performance (0.49 Watt/cm 2 at 800 • C) for the given elect…
Las propiedades físico-químicas del bismuto y sus óxidos han sido objeto de estudio en las dos últimas décadas. Como resultado de estas investigaciones, estos materiales se han logrado crecer en diferentes estructuras cristalográficas y con dimensiones micro y nanométricas, utilizando diferentes técnicas (pulverizació…
Mn 2+ ions codoped Sr 2 SiO 4 : Dy 3+ phosphors were prepared by the solid‐state reaction method using NH 4 Cl as the flux. Their phase compositions, photoluminescence properties, and the energy transfer process were systematically investigated. All Mn/Dy codoped powders were α ′‐Sr 2 SiO 4 . The codoping concentratio…
Environmental pollution is one of the global hot issues and need an urgent demand to detect and monitor the pollutants which affect the environment. Ethanol is one of the organic pollutants which cause severe harmful effect on environment due to its toxic nature. For the detection and quantification of organic polluta…
Most of the researchers have been reported about the nontoxic biosynthesis of silver nanoparticles using several microorganisms and plant extracts. This ecofriendly silver nanoparticles exhibit completely new or improved properties based on specific characteristics such as size, distribution, morphology and many appli…
A two-step chemical oxidation of multiwalled carbon nanotubes (MWCNTs) with different oxidation reagents was particularly studied. The reagents used in first step were the acidic mixture of sulfuric acid and nitric acid, and the reagents used in the second step were a mixture of sulfuric acid and hydrogen peroxide for…
The purpose of this paper is to present Air pollution generated from mobile sources is a problem of general interest. Vehicle population is projected to grow close to 1300 million by the year 2030. Due to incomplete combustion in the engine, there are a number of incomplete combustion products CO, HC, NOx, particulate…
