Adsorption-driven separation of CO2 from flue gas has the potential to cut the cost for carbon capture and storage. Among the porous physisorbents, metal–organic frameworks (MOFs) are a class of promising candidates for gas separation and storage owing to their extraordinarily high specific surface areas and pore volu…
Porous coordination polymers (PCPs), with their ordered nanoporous systems and large surface areas, are very attractive for numerous applications that involve controlled molecular transport properties. To fully exploit their potential, a straightforward processing method to deposit the PCP crystals on various substrat…
Based on the aggregation-induced fluorescence quenching mechanism, a 2,6-dithienyl-4-phenylpyridine-containing conjugated polymer (P-A) has been designed and synthesized via a Sonogashira coupling reaction as an efficient fluorescent sensor for palladium and platinum ions. The metal ion-sensitivity of P-A was evaluate…
Highly efficient multilayered polymer-based phosphorescent organic light-emitting diodes (PhOLEDs) are realized by orthogonal sequential solution-processing of commercial small-molecule electron-transport materials (ETMs), including 1,3,5-tri(3-pyrid-3-yl-phenyl)benzene (TmPyPB), 4,7-diphenyl-1,10-phenanthroline (BPhe…
The severe accident that broke out at Fukushima Dai-ichi nuclear power stations on March 11, 2011, caused seemingly infinite damage to the daily life of residents. Serious and wide-spread contamination of the environment occurred due to radioactive materials discharged from nuclear power stations (NPSs). At the same t…
The present work provides a new, well characterized hydroxyl functionalized biocompatible and degradable polymer that could be suitable for many different biomedical applications. Poly(2-hydroxyethyl methacrylate) (PHEMA) is a widely used and researched biocompatible polymer, but lacks degradability. In this work, deg…
Titanium dioxide nanoarchitectures with well-defined morphologies have been successfully synthesized by a hydrothermal process at temperature 180 °C for 4 h using titanium butoxide, oleic acid and hydrochloric acid as precursor materials. Different hierarchical morphologies such as cauliflower, 3D microsphere, densely…
Cell sheet technology is a tissue engineering methodology requiring no scaffolds. Confluent cultured cells can be harvested as an intact cell sheet using a temperature-responsive polymer, poly(N-isoproplyacrylamide) (PIPAAm), grafted cell culture surface, offering noninvasive control of cell attachment and detachment…
A new aggregation-free branch-type organic dye for dye-sensitized solar cells (DSCs) is developed by means of a twisting π-conjugation strategy. In comparison with the analogue planar dye, the twisting dye shows excellent potential as a new aggregation-free organic dye for DSCs.
A novel type of amphiphilic ionic copolymer comprising a hydrophilic poly(acrylic acid) (PAA) block and an amphiphilic poly(acrylic acid)-grad-poly(styrene) (PAA-grad-PS) copolymer block was synthesized using a one step direct nitroxide-mediated polymerization (NMP). A strong influence of the macroinitiator on the val…
The binding of intrinsically disordered proteins (IDPs) to structured targets is gaining increasing attention. Here we review experimental and computational studies on the binding kinetics of IDPs. Experiments have yielded both the binding rate constants and the binding mechanisms, the latter via mutation and deletion…
Symmetrical silver phosphate (Ag3PO4) crystals with porous structure were grown by a facile controllable route in aqueous solution. The Ag3PO4 crystals have a cubic-type structure and the morphologies are distinctive under different conditions. The crystals had high purity, were well-crystallized and were free of seco…
We present a quantitative study of the catalytic activity of well-defined faceted gold-palladium nanoalloys which are immobilized on cationic spherical polyelectrolyte brushes. The spherical polyelectrolyte brush particles used as carriers for the nanoalloys consist of a solid polystyrene core onto which cationic poly…
Polyaniline nanowires (PANI) and gold nanoparticle (AuNPs) based hybrid nanocomposite film fabricated onto a Au substrate has been used to fabricate a mediator free immunosensor for the detection of PSA. Microscopic studies reveal uniform distribution of the AuNPs on the PANI backbone resulting in a nanoporous morphol…
Two-dimensional (1)H double-quantum and (14)N-(1)H & (1)H-(13)C heteronuclear magic-angle spinning (MAS) NMR spectra recorded at natural isotopic abundance identify specific intermolecular COOH···N(arom) and CH(arom)···O=C hydrogen-bonding interactions in the solid-state structure of an indomethacin-nicotinamide cocry…
New dipolar compounds containing a 5,6-bis-hexyloxy-benzo[2,1,3]thiadiazole entity in the conjugated spacer between the electron donating arylamine and the electron accepting 2-cyanoacrylic acid have been synthesized. These compounds were used as the sensitizers for efficient dye-sensitized solar cells. Compared to th…
The changes in the structure of 45S5 Bioglass® and its heat-treated versions upon SrO substitution were investigated by solid-state multinuclear magic angle spinning nuclear magnetic resonance (MAS-NMR), X-ray diffraction and differential scanning calorimetry. A series of the melt-derived glasses with SrO gradually su…
Two chiral lead metal–organic nanotubes (CD-MONT-2 and CD-MONT-3) based on β-cyclodextrin (β-CD) and γ-cyclodextrin (γ-CD) were synthesized through a biphasic solvothermal reaction. The lead ions were connected by two β-CD or γ-CD molecules through their glycosidic oxygen atoms to generate a discrete metal–organic nan…
New molten salt chemistry allows solar thermal energy to drive calcium oxide production without any carbon dioxide emission. This is accomplished in a one pot synthesis, and at lower projected cost than the existing cement industry process, which after power production, is the largest contributor to anthropogenic gree…
Two isostructural microporous metal–organic frameworks [Co(DMA)6]3[(Co4Cl)3(BTT)8(H2O)12]2·12H2O (BTT3− = 1,3,5-benzenetristetrazolate; DMA = N,N′-dimethylacetamide) (1) and [Cd(DMF)6]3[(Cd4Cl)3(BTT)8(H2O)12]2·14H2O·4DMF (DMF = N,N′-dimethylformamide) (2) were synthesized under solvothermal conditions.
