In the present contribution, we report the synthesis of thermoresponsive homo and statistical copolymers of N -vinylcaprolactam and N -vinylpyrrolidone and the corresponding responsive gold nanoparticles.
Cashmere-derived keratin is extracted in water solution and then processed using a slow drying technique to obtain flexible, transparent, conformable optical elements.
A new method was developed through an efficient Förster resonance energy transfer (FRET) from guanidinium-pendant oligofluorene to green fluorescent protein (GFP) for specifically screening membrane-disrupting antibiotics to which bacteria have difficulty developing resistance.
For post-synthetic metallation (PSMet) of a metal–organic framework (MOF, [Mn3(L2)(L')] = 1) we show a solvent dependency for the form of the metallated product. PSMet of 1 with MnCl2 in ethanol leads to a single metal entity per coordinating site while acetonitrile yields a remarkably complex multiply metallated prod…
The role of auxiliary solvents in the formation of metal-organic frameworks (MOFs) has been studied for a series of copper-based framework systems. Herein we show the formation of three different 3D ordered frameworks with the formulae {[Cu4(cpt)4Cl4]·2DMF·dioxane·3H2O}n (1), {[Cu8(cpt)4(Hcpt)2Cl7(μ3-OH)2(H2O)4]Cl3·4C…
The degradable behavior of a hydrogel under varying pH was observed using SEM.
A Pt/UltraPPy modified glassy carbon electrode is a highly sensitive new sensor for the detection of dopamine.
Nickel oxide (NiO) thin films with thickness ranging in the interval 0.2 - 3.5 μm have been deposited onto conductive transparent substrate via the method of plasma-assisted rapid discharge sintering (RDS) with microwave heating starting from NiO nanoparticles with diameter 50 nm. The optical and electrochemical prope…
A new spinel-style S 2 O 8 2− /ZnAl 2 O 4 catalyst with the mesoporous structure exhibited the well catalytic activity and structural stability.
Highly ordered nitrogen‐doped titanium dioxide (N‐doped TiO2) nanotube arrays were prepared by anodic oxidation method and then annealed in a N2 atmosphere to obtain N‐doped TiO2 nanotube arrays. The samples were characterized with scanning electron microscope (SEM), X‐ray powder diffraction (XRD), X‐ray photoelectron…
Polymer solar cells (PSCs), with poly(diketopyrrolopyrrole-terthiophene) (PDPP3T):[6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) as the active layers, were fabricated using solutions of different temperatures. The best power conversion efficiency (PCE) of the PSCs prepared using a hot solution was about 6.22%, wh…
Lanthanide cations tune the infrared absorption characteristics of the capping ligands in Zn(Ln)S [Ln = Sm, Eu, Tb, Dy] nanoparticles.
The morphology and composition of copper powder obtained by electrospark dispersion of waste from copper electrical wire are investigated. The primary chemical element in the powder is copper (98.69%).
Salts of 3,5-dinitro-1H-1,2,4-triazole, a building block for energetic materials, have been prepared and fully characterized. Most of the studied salts exhibit high thermal stability and very low shock and friction sensitivities. 3,5-Dinitro-1,2,4-triazolates with the nitrogen-rich ammonium, guanidinium, aminoguanidin…
Opposite magnetic switching was achieved in ZnO with different electrodes under an electric field. This can be used to alter the magnetism.
The adsorption of aluminium(III) and iron(III) ions from their single and binary systems, by RHAC was investigated in a batch system. The activated carbon prepared from rice hulls was characterized by scanning electron microscopy and Fourier transformation infrared techniques. Batch adsorption experiments were perform…
Hierarchical beta (SiO 2 /Al 2 O 3 = 25–50) with enhanced catalytic properties in 1,3,5-TIPB cracking reaction is synthesized using PDADMA as a bifunctional template assisted by seeds under rotational conditions.
The amino groups of a novel oligomer of amino-cyclodextrins play a relevant role in the recognition process of diclofenac and this highlights the potential of short polymeric chains as new drug carriers.
A novel Fe 3 O 4 /SiO 2 /P(GMA- co -EGDMA)–Pd(0) catalyst and its highly effective activity for Sonogashira cross-coupling reactions.
Surface defects and impurities play important roles in the photocatalytic performance of semiconductors. In this study, DFT calculations are performed to investigate the effects of oxygen impurities and nitrogen vacancies on the surface stability and electronic structures of Ta3N5(100), (010) and (001) low-index surfa…
