Here we report the synthesis of barium sulphate (BaSO 4 ) nanoparticles from Ba(OH) 2 /BaCl 2 solutions by a combined method of precipitation and quenching in absence of polymer stabilizers. Transmission electron microscopy (HRTEM), Fourier transforms infrared spectroscopy (FTIR), and X‐ray diffraction (XRD) were empl…
MWCNTs–MnO <sub>2</sub> anodes and MWCNTs–MoO <sub>3</sub> cathodes were screen printed on carbon nanoparticle flexible electrodes for supercapacitor applications.
Silica content, saturation temperature and pressure all have an effect on silicone rubbers' viscoelastic properties, which further has a close connection with the cellular structure.
The results obtained for binder-free electrodes made of carbon monoliths with narrow micropore size distributions confirm that the specific capacitance in the electrolyte (C2H5)4NBF4/acetonitrile does not depend significantly on the micropore size and support the foregoing constant result of 0.094 ± 0.011 F m(-2).
We present a new type of <italic>in situ</italic> reduction-assembly approach to construct graphene hydrogel through simultaneous water evaporation and graphene oxide reduction.
. One-cell-stage zebrafish embryos microinjected with Ru-MO and incubated in the dark for 24 h developed normally, consistent with caging, whereas irradiation at 450 nm dissociated one 3-ethynylpyridine ligand (ϕ = 0.33) and uncaged the MO to achieve gene knockdown. As demonstrated, Ru photolinkers provide a versatile…
molecules per s under our conditions. Consequently, this work may open new horizons in applications of molecular switches based on VT metal complexes in molecular devices functioning at room temperature.
A new and facile method was used to transfer upconversion luminescent nanoparticles from hydrophobic to hydrophilic using polyhedral oligomeric silsesquioxane (POSS) linking on the surface of upconversion nanoparticles. In comparison with the unmodified upconversion nanoparticles, the POSS modified upconversion nanopl…
The mechanical mixing and hot compaction method was firstly used to fabricate graphite/polymer segregated composite for efficient electromagnetic interference shielding.
High quality graphene has been obtained by polysaccharide-assisted ultrasonication in aqueous medium. This approach provides an economical, solvent-free, high-yield, and industrially scalable route for new applications of graphene-based nanocomposites.
Four different thermal manikins (male and female shapes)in three different laboratories (UK, Sweden, and China) were used to determine the clothing thermal insulation values of 52 non-Western, mainly indoor clothing ensembles in order to expand the existing clothing database for use with ANSI/ASHRAE Standard 55-2013,…
Modification of citrate and hydroxylamine reduced Ag colloids with thiocholine bromide, a thiol functionalized quaternary ammonium salt, creates particles where the zeta potential is switched from the normal values of ca.-50 mV to ca. +50 mV. These colloids are stable but can be aggregated with metal salts in much the…
Photoswitchable transistors based on a blend of an n-type fullerene derivative and a photochromic diarylethene can be gated either through the gate electrode or by photoisomerization of the diarylethene molecules.
Demonstration of a high brightness, strong green emitting, water resistant and flexible phosphorescent layer for display and defence applications.
Photoelectrodes of Al-doped La <sub>5</sub> Ti <sub>2</sub> Cu <sub>1−x</sub> Ag <sub>x</sub> S <sub>5</sub> O <sub>7</sub> powder generate a photocathodic current attributable to the hydrogen evolution reaction at +0.7 V <italic>vs.</italic> RHE.
Photo-induced spin transition in a molybdenum-zinc complex has been evidenced and fully characterized by Squid magnetometry and several spectroscopies performed under irradiation (IR, EPR, etc.). The phenomenon has been confirmed by X-ray diffraction and DFT calculations yielding a Light-Induced Excited Spin State Tra…
Red to near infrared ultralong lasting luminescence was observed from Mn <sup>2+</sup> -doped sodium gallium aluminum germanate glasses and (Al,Ga)-albite glass-ceramics.
A series of Eu(2+) and Tb(3+) singly-doped and co-doped β-Ca3(PO4)2 phosphors have been synthesized via the high-temperature solid-state reaction method. Thermogravimetric (TG) analysis, fourier transform infrared (FT-IR) spectra, X-ray diffraction (XRD) patterns and Rietveld refinements, photoluminescence (PL) spectr…
Simple surface functionalization of GO was employed with the quantum confined CdS towards the fabrication of pn hetero-junction based solar cell.
Solution-processed high-efficiency p–n heterojunction photodetectors have been developed using transition metal oxides.
