The solid solution (SS) method is an effective way to design impactful photocatalysts, owing to its merit of continuous bandgap-tuning. A calcination, usually breaking the morphology of a material, has to be used to synthesize such catalysts, although the morphology is a critical issue affecting its catalytic behavior…
An alkaline, tartrate-complexed copper electrolyte containing additives that provide bottom-up fill is described. Bottom-up fill is achieved using a mixture of two additives: bis-(3-sulfopropyl) disulfide (SPS) and polyethyleneimine (PEI). Chronopotentiometric studies indicate that, unlike in conventional acidic elect…
An easy reversible switching of the electronic ground state in a pentacoordinated copper(II) complex is reported for the first time. The simple protonation of a carboxylic group in a Cu(II) complex with a {dx(2)-y(2)}(1) electronic configuration leads to a flip of the ground electronic configuration from {dx(2)-y(2)}(…
Homochiral crystallizations of single-stranded helical coordination polymers were constructed using the V-shaped bridging ligand dicyanamide (μ1,5-dca−) and chelate auxiliary ligands. The enantiomeric nature of 1 and 2 is directly induced by the chirality of the auxiliary ligands. Whereas, the homochirality feature fo…
The selection of the halogen bonding (XB) donor is an important factor in molecular recognition of halides by XB. Here XB complexes between tetraiodoethylene (TIE) as another donor instead of iodoperfluorobenzene and halides are investigated using UV-Vis, Raman, FT-IR, XRD, PXRD and calculations. A 1 : 1 stoichiometry…
Computer simulations have been carried out to investigate the possibility of extending operating cycle length in the Pressurised Water Reactor Ringhals 3 by the use of thorium-plutonium oxide fuel. The calculations have been carried out using tools and methods that are normally employed for reload design and safety ev…
The composite of hard carbon and nano-graphite (HCNG) is prepared by the pyrolysis of sucrose with the catalysis agent. In HCNG, nano graphite particles are imbedded in hard carbon. HCNG is used as the anode material for lithium ion battery and shows a low and flat discharge platform, which is similar to that of graph…
The physicochemical properties and catalytic activity of pure and sulfated titanium oxide (TiO2 and ) is described in this work. Titanium hydroxide synthesized by the sol-gel method was impregnated with a 1 N H2SO4 solution, varying amount of sulfate ions () in the range from 10 to 20 wt%. Pure and modified hydroxides…
The elementary charge and excitation energy transfer steps in a novel symmetric donor-acceptor-donor triad first described in Roland et al. Phys. Chem. Chem. Phys., 2012, 14, 273, consisting of a central perylenediimide moiety as a potential electron acceptor and two identical electron rich bithiophene compounds, have…
A novel approach for mimicking Aβ aggregation and its infection pathway using a liposome as an artificial cell environment.
To correlate the cationic contaminant uptake of the catalyst coated membrane (CCM) with the polymer electrolyte fuel cell (PEFC) performance, CCMs were contaminated by saturating in varying concentrations of H 2 SO 4 and Al 2 (SO 4 ) 3 solution, establishing ex-situ equilibrium cation uptake. The CCMs were then assemb…
A method has been proposed for self-consistent calculations of characteristics of a metal film in dielectrics. The most interesting (asymmetric) case of metal-dielectric sandwiches, where the dielectrics are different on both sides of the film, has been considered in terms of the modified Kohn-Sham method and the stab…
A study of the wet chemical etching of InP has been used to develop an oxide formation/oxide dissolution (OFOD) model that allows for ESH acceptable cleaning of InP in both acidic and alkaline solution. Using this approach toxic PH3 formation is prevented and a smooth surface finish is obtained. Mixtures for post-CMP…
A novel transparent conductive oxide (TCO)-free monolithic back-contact dye-sensitized solar cell (mBC-DSC) architecture is proposed, capable of achieving conversion efficiencies of 4.6%. The mBC-DSCs consist of two coplanar charge-collecting electrodes separated by a porous ZrO2 spacer layer. The mesoporous dye-sensi…
A novel pH probe based on hemi-cyanine was synthesized, which displays extremely large Stokes shift (122 nm) and good photostability. The probe responds to basic pH (pKa 8.32) with a colorimetric and fluorescence turn-on signal. Interestingly, the probe has good cell membrane permeability and could selectively stain n…
Depletion can induce aggregation of nanoparticles and therefore has been employed for size fractionation of nanoparticle dispersions. In this study, depletion-induced separation of solvophilic nanorods in polymer solution is explored via dissipative particle dynamics. Three possible equilibrium states are observed upo…
For the first time, nanostructures of 18R (Mg85Zn6Y9) LPSO (long-period stacking-ordered) were examined using STM (scanning tunneling microscopy), which unambiguously confirmed the proposed model of the atomic structure of the LPSO phase in which the Zn–Y clusters are arranged in a two-dimensional hexagonal lattice in…
Induction cookers are popular in the modern family in Hong Kong. Since these cookers do not use naked flame, some people believed that these induction cookers will not create any fire hazard and can be considered as a fire safety feature. Therefore, with induction cookers installed in the kitchen, it is possible to re…
Two new series of phosphonato-substituted bithiophenes, BpP(X)(C4H2S)2H and BpP(X)(C4H2S)2P(X)Bp (Bp = 2,2'-C12H8O2, X = O, S, Se), have been synthesized and characterized using linear absorption and emission spectra, and third-order nonlinear absorption measurements at 430 nm with 27 ps laser pulses. The compounds we…
Perfusion culture systems are widely used in tissue engineering applications for enhancing cell culture viability in the core of three-dimensional scaffolds. In this work, we present a multichamber confined-flow perfusion system, designed to provide a straightforward platform for three-dimensional dynamic cell culture…
