A novel porous material is prepared by octavinylsilsesquioxane and brominated distyrylpyridine via the Heck coupling reaction, which exhibits an excellent pH-responsive property in the pH range from 1 to 4.
The purpose of this study was to characterize the interactive effects of light and aging on physicochemical properties and antimicrobial activity of nanocrystalline silver wound dressings Acticoat that might find their way into the environment.
Organic bioelectronics is making an enormous impact in the field of tissue engineering, providing not just biocompatible, but biofunctional conducting material platforms. For their true potential to be reached, it is critical to integrate organic conductors with other biopolymers in a targeted manner, allowing the dev…
Molecular dynamic simulation was used to calculate the critical stresses necessary for dislocations to nucleate and move in the dynamic friction mode and determine the coefficients of dislocation phonon friction in metals with point defects and Guinier-Preston (GP) zones (in the Al-Cu alloy) taken into account. The te…
Hybrid nanoparticle based on quantum dots and dye labeled PNIPAM shows ratiometric changes in fluorescence emission upon temperature cycling between 25 °C and 45 °C.
To screen the possibility of forming self-assembled hydrogels under physiological pH, various molar ratios of the hydrogelators based on pentafluorobenzyl-phenylalanine (PFB-F) and pentafluorobenzyl-diphenylalanine (PFB-FF) were studied.
The development of studies on the preparation, physicochemical properties, and possible applications of carbon nanomaterials in power manufacturing, conversion, and storage systems is analyzed in this review. The authors continue to study the problem of systematization and attestation of numerical data for nanoscale o…
The toxicity of CDs in mice and zebrafish and the potential relationship between toxicity and autophagy was evaluated.
Thin films composites of poly(ethylene oxide)‐graphene oxide were fabricated with and without lithium salts by solvent cast method. The ionic conductivity of these composites was studied at various concentrations of salt polymer‐GO complexes and at different temperatures. The effects of temperature and graphene oxide…
The inclusion of a ligated ruthenium moiety to ethynyl spiropyran, 5'-ethynyl-1',3',3'-trimethyl-6-nitrospiro[chromene-2,2'-indoline], has been shown to increase the lifetime of the ring-opened merocyanine form twentyfold. Calculations suggest that the higher barrier to thermal reversion of the merocyanine form of the…
In this work, thermosetting resin, epoxy and fibre loading were used in optimizing the strength at which ABS/epoxy coated kenaf fibre (EKF) composites would perform apparently during mechanical stress. Kenaf bast fibres were resin coated before incorporated into engineering thermoplastic ABS at its processing temperat…
This work investigated the use of nickel/yttria stabilized zirconia (Ni/YSZ) coated in situ with chromium oxide (Cr 2 O 3 ) for electrochemical methane (CH 4 ) reforming in solid oxide electrolysers.
This highlight deals with the recent advances on the synthesis in aqueous solution of one-dimensional vanadium( v ) oxide nanocrystals.
Effect of annealing temperature on microstructure and superelasticity of Ti-4Au-5Cr-8Zr (mol%) was investigated. Only phase was observed in the specimen annealed at 1173 K, whereas the precipitation of Ti 3 Au, Zr 33 Ti 40 Au 27 (Laves phase) and phase occurred in the specimens annealed below 1073 K. Superelasticity w…
Novel enzyme composites are synthesized first by in situ polymerization around enzymes and a subsequent sol-gel process. Both the polymer shell and the silica shell with desired functional moieties provide not only great enzyme protection but also a favorable microenvironment, resulting in significantly enhanced activ…
This synergism, resulting from the combination of luminescence and DSSCs, opens up the way to new multifunctional materials.
The physical foundations and methodological issues of nuclear activation methods (radiotracers and neutron activation analysis) have been discussed in regards to a study of assimilation of a number of inorganic nanoparticles (NPs) by living organisms and their distribution in organs and excretion. The methods of activ…
There is growing interest in the development of novel nanomaterials with potential antimicrobial activity and lesser toxicity. In the current research work, Mn0.5Zn0.5Fe2O4 nanoparticles were synthesized via a novel coprecipitation cum laser ablation technique yielding fine spinal structured material. The synthesized…
The spectra and decay of luminescence in scintillation glass of the Li 2 O-B 2 O 3 -P 2 O 5 -CaF 2 system doped by Gd, Gd/Ce, Gd/Pr, Tb, Tb/Ce, and Tb/Eu have been investigated. The technology of synthesis has been described and the evolution of luminescence spectra relative to the electron excitation pulse has been s…
Effect of carbon (C) content on heat treatment behavior of multi-alloyed white cast irons with basic alloy composition was investigated. The multi-alloyed white cast irons with varying C content of 1.73–2.34% were prepared. After annealing, the test specimens were austenitized at 1323 and 1373 K, and then hardened by…
