In this study, photocatalytic reduction of hexavalent chromium [Cr(VI)] by amorphous FeOOH was investigated with variations in FeOOH dosage, pH, initial Cr(VI) concentration, purging gas, organic compounds and initial hydrogen peroxide concentration. Reduction and adsorption were identified as important processes for…
Micro powders of recycled wool and cotton from textile waste is prepared and characterized. Wool and cotton waste fibers were frozen in liquid nitrogen and milled for various period times to produce fine powders. The powders sizes distribution depends on the milling time. Scanning electron microscopy micrographs confi…
A homochiral helical coordination polymer of copper(II) has been synthesized using achiral precursors via spontaneous symmetry breaking and has been confirmed by single crystal X-ray diffraction and solid-state CD spectroscopy. The variable temperature magnetic measurements indicate the presence of weak ferromagnetic…
This communication reported an intuitive and convenient approach to detect the structural heterogeneity of carbon fibers by using Raman spectroscopy. As indicated by both the linear and mapping modes, the skin–core difference was enhanced with the rising temperature during the graphitization. This enhanced structural…
In this work, we have demonstrated chemically coupled (3-aminopropyl)trimethoxysilane (APTMS) and 3-mercaptopropionic acid (MPA) self-assembled monolayers (SAMs) to enhance the diffusion barrier properties against copper (Cu) as well as the adhesion properties towards SiO2 and Cu electrode. The coupled-SAM (C-SAM) can…
We demonstrate stretchable organic thin-film transistors (OTFTs) on a polyimide stiff-island/elastomer substrate. All processes are performed entirely at elastomer-compatible temperatures. We confirm the basic properties of the poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] with a poly(methyl methacrylate)…
Graft polyrotaxanes, with poly(ε-caprolactone) (PCL) graft chains on the ring components were synthesized by the simultaneous ring-opening polymerization of ε-caprolactone from both ends of the backbone polymer, an end-functionalized polyethylene glycol (PEG) and the formation of inclusion complexes with α-cyclodextri…
High efficiency small molecules were synthesized and characterized in solution-processed organic solar cells. These were star-shaped comprising of fused triphenylamine donating core, hexyl cyano acetate or methylene malononitrile accepting edges, and alkyl-substituted therthiophene bridge unit, exhibiting a noteworthy…
Diatrizoic acid (DTA), a clinically used X-ray contrast agent, crystallises in two hydrated, three anhydrous and nine solvated solid forms, all of which have been characterised by X-ray crystallography. Single-crystal neutron structures of DTA dihydrate and monosodium DTA tetrahydrate have been determined. All of the…
Drug promiscuity and polypharmacology are much discussed topics in pharmaceutical research. Experimentally, promiscuity can be studied by profiling of compounds on arrays of targets. Computationally, promiscuity rates can be estimated by mining of compound activity data. In this study, we have assessed drug promiscuit…
Analytical expressions for the normalized transmittance of a thin material with simultaneous nonlocal nonlinear change in refraction and absorption are reported. Gaussian decomposition method was used to obtain the formulas that are adequate for any magnitude of the nonlinear changes. Particular cases of no locality a…
Abstract An interface microenvironment between nanocarbon and ionic liquids (ILs) is presented. By an entrapping effect, a few layers of ILs can be finely deposited on the surface of nanocarbon, endowing amazingly tailorable surface properties. The entrapped IL layer, which was believed to be unable to be charred unde…
Tetraimidazolylborate is first used as the counterion of two novel ionic iridium complexes, instead of tetraphenylborate. Both the electrochemical stabilities and electroluminescence are sharply improved. Organic light-emitting diodes have been successfully fabricated with a high current efficiency of 9.48 cd A(-1) an…
Reaction of small increments of NO2 gas with sublimed amorphous layers of Mn(II)(TPP) (TPP = meso-tetra-phenylporphyrinato dianion) in a vacuum cryostat leads to formation of the 5-coordinate monodentate nitrato complex Mn(III)(TPP)(η(1)-ONO2) (II). This transformation proceeds through the two distinct steps with init…
Abstract A bistable bis‐branched [3]rotaxane with a perylene bisimide (PBI) chromophore that separates two mechanically interlocked [2]rotaxane arms including a diferrocene‐functionalized dibenzo‐24‐crown‐8 ring, was designed, prepared, and characterized by 1H NMR and 13C NMR spectroscopy and HR‐ESI mass spectrometry.…
Plasmonic black surfaces formed by two-dimensional arrays of ultra-sharp convex metal grooves, in which the incident radiation is converted into gap surface plasmon polaritons (GSPPs) and subsequently absorbed (via adiabatic nanofocusing), are fabricated and investigated experimentally for gold, nickel, and palladium,…

Previously we have demonstrated surface plasmon enhanced energy transfer between fluorophores and gold nanorods under two-photon excitation using fluorescence lifetime imaging microscopy (FLIM) in both solution and intracellular phases. These studies demonstrated that gold nanoparticle-dye energy transfer combinations…
A novel time-resolved luminescence biosensor assay for anaplastic lymphoma kinase (ALK) was developed. We used a straightforward strategy to modify a known ALK substrate into a peptide biosensor that can accommodate terbium luminescence sensitization upon its phosphorylation by ALK. Since this strategy is generalizabl…
Non-selective luminescence spectroscopy and luminescence line-narrowing spectroscopy were used to study the retention of UO2(2+) on titanium dioxide (TiO2), synthetic calcium silicate hydrate (C-S-H) phases and hardened cement paste (HCP). Non-selective luminescence spectra showed strong inhomogeneous line broadening…
