A combination of cobalt(II) complexes and pyridine ligands carrying organic spins, aminoxyl and carbene, provided single-molecule magnets with Stotal = 3/2 in diluted frozen solutions.
In order to explore synthetic approaches to strongly emitting nanoparticles covering the UV–blue spectral region, the photochemical treatment of ZnSe and Zn1−xCdxSe nanocrystals (NCs) capped by thioglycolic acid (TGA) in the presence of Zn2+ and Cd2+ ions was investigated. A reproducible method of tuning the luminesce…
The favorable lattice matching between Au and NiO crystals made possible the growth of unique cookie-like nanoparticles (25 nm mean diameter) inside a porous SiO 2 film by simply tailoring the film synthesis parameters. The unusual aggregates result from the coupling of well distinguishable Au and NiO hemispheres, whi…
An antiphase boundary (APB)-like structure in the B19 martensite of Ti-Pd alloy has been investigated by transmission electron microscopy. High-resolution and high-angle annular dark-field scanning transmission electron microscopy images demonstrate the presence of an APB-like contrast along the (001) basal plane of t…
We studied the oxidant addition effect on chemical mechanical polishing (CMP) of (GST) phase change film. Atomic force microscopy and scanning electron microscopy (SEM) were used to characterize GST CMP performance. The surface roughness was reduced from by oxidant addition. The surface chemical state of GST after bei…
The effect of electron-beam (EB) irradiation on the impact value of silica glass was studied by means of a standard Charpy impact test. When it performed in short bursts to maintain a low temperature, EB irradiation at a dosage of less than 0.216 MGy increased the impact value of the glass. Because the EB irradiation…
Cotton fabric was grafted with a poly (acrylamide-co-itaconic acid) co-polymer via ceric ammonium nitrate (CAN) induced graft co-polymerization in an aqueous medium. The grafted cotton fabric was loaded with Ag nanoparticles by entrapment of Ag + ions into a grafted polymer network, followed by borohydride reduction.…
A series of ( , ; , ) phosphors was synthesized by the evacuated sealed quartz ampoule method. X-ray powder diffraction analysis confirmed the formation of the complete solid solutions of and . With the and content increasing, the emission peaks of and show an obvious blueshift in the range of . A tunable bluish-green…
Alginate/poly-L-ornithine/alginate (APA) coherent microencapsulation, which provides an immunoselective and highly biocompatible membrane, creates a viable option for cellular or tissue transplantation. This study explored the potential of incorporating immunosuppressive drugs onto the capsule surface to provide local…
Hydrogen peroxide formation is achieved with remarkable productivity at ambient conditions (25 degrees C and atmospheric pressure) in aqueous medium using a heterogeneous catalytic system; formic acid is decomposed in the presence of a continuous flow of O(2) over Pd/gamma-Al(2)O(3) catalyst leading to the generation…
Making alloys of Mg and Li is quite a task as their individual melting temperatures are vastly different. However, it is thought paid off considering their extreme lightness. Basically, low melting temperature Li could cause Mg-Li alloys’ microstructures change at room temperature (R.T.). Recrystallization and aging o…
A functionalized ethylenedioxythiophene (EDOT) derivative bearing a highly nucleophilic thiolate group has been synthesized. The efficiency of this new building block as a precursor to a wide range of EDOT-based monomers is demonstrated by reaction with different electrophilic species or by oxidation to a disulfide di…
Ring expansions or contractions of metalloporphyrins are unusual reactions. In this review, the author will show how the step by step analysis of two serendipitous reactions allows one to unveil their mechanism and to point out the key role of nickel ion in these rearrangements.
The catalytic dehydrogenation of LiBH(4) doped with exceptionally low quantities of carbon-supported Pt nanoparticles can be improved significantly, and smaller Pt nanoparticles result in greater enhanced catalytic dehydrogenation of LiBH(4) than do larger Pt nanoparticles.
Ag nanoparticles (NPs) formed in situ by the photochemical reduction of phosphotungstic acid (H3PW12O40, PTA) under UV-irradiation in polyelectrolyte multilayer nanoreactors composed of poly(ethyleneimine)–silver ions (PEI–Ag+) and PTA fabricated on solid substrates by alternating adsorption, wherein the PTA plays the…
Nano-crystalline MWO4 (M = Ca, Sr and Ba) were successfully produced using cyclic microwave radiation in propylene glycol. XRD, TEM, SAED and EDX analyses revealed the presence of nano-crystalline MWO4 containing the corresponding alkaline earth metals, W and O. Their lattice parameters and crystallite sizes were dete…
Here we describe peptide amphiphiles (PAs) which can be self-assembled into nanofiber networks using divalent ions. These networks possess several key properties of extracellular matrix (ECM) including cell-adhesive ligands, enzyme-mediated degradation and self-assembly into hierarchical organization. The self-assembl…
Crystal growth behaviors in CuO-doped Li2O-2SiO2 glasses by continuous-wave (cw) Ytterbium doped fiber laser (wavelength: 1080 nm) irradiations are examined. The lines (width: ~5 μm) consisting of highly oriented nonlinear optical lithium disilicate (Li2Si2O5) crystals are patterned in various laser powers (1.2-2.4 W)…
