Diarylethene crystals were found to exhibit photoinduced stepwise bending behavior. The bending rate changed significantly during continuous irradiation with ultraviolet (UV) light. This is a new type of photomechanical motion reported previously for various photoresponsive molecular crystals. Furthermore, the delayed…
Tunable properties from transparent conducting to photon down-shifting are obtained with slight change in O <sub>2</sub> pressure during Nd:ZnO film growth.
Two-dimensional tungsten diselenide (WSe2) has been used as a component in atomically thin photovoltaic devices, field effect transistors, and tunneling diodes in tandem with graphene. In some applications it is necessary to achieve efficient charge transport across the interface of layered WSe2-graphene, a semiconduc…
Using renewable resources like cardanol aiming towards development of bio-derived coordination polymers with nanoporous layered morphology, amorphous/crystalline behavior, and better thermal stability having moderate adsorption capacity towards dye.
The design of stable polymeric micelles that can respond to specific stimuli is crucial for the development of smart micellar nanocarriers that can release their active cargo selectively at the target site, thus diminishing the therapeutic limitations due to non-selective damage to healthy tissues. Here we report the…
Construction of a site-isolated heterogeneous catalyst to realize the compatibility of bimetallic complexes for a feasible tandem reaction is a significant challenge in heterogeneous asymmetric catalysis. Herein, taking advantage of yolk-shell-structured mesoporous silica, we assemble an active site-isolated bifunctio…
During final stage sintering, a complex interplay of densification and grain growth dominates microstructural evolution. Grain growth starts, when pore drag effects become less important due to pore shrinkage. This grain growth then decreases the driving force available for sintering. Accordingly, the interplay of por…
Star-shaped and linear thermo-responsive PNIPAM polymers were compared for the functionalization of SWNTs. The star-shaped polymer gave the SWNTs a higher solubility and more thermo-responsive properties than its linear counterpart.
Asian Journal of Chemistry, a Multidisciplinary Chemistry Journal is an Peer Reviewed International Journal and publishes from India. The journal has been established since January 1989 on a firm foundation of International Quality Research. This Journal encompasses all branches of chemistry and its sub – disciplines…
Trimers with one attractive bead and two repulsive beads, similar to recently synthesized trimer patchy colloids, were simulated with flat-histogram Monte Carlo methods to obtain the stable self-assembled structures for different shapes and interaction potentials. Extended corresponding states principle was successful…
Polyanilines (PANIs) have been synthesized by the emulsifier free polymerization process utilized Ammonium Persulphate (APS) as an initiator at room temperature (28 C). The complete reaction of polymerization process was indicated by increasing viscosity from 20 mPa.s to 180 mPa.s. A particle size formation also was o…
UV, visible, and solar light activations gave different optimum loadings of CuO due to the different masking effects of CuO photodeposited on TiO <sub>2</sub> .
In this work the effect of multivalency on the stability of NIR-absorbing HAuNSs and AuNRs functionalized by mono-, bi- and tridentate polyethyleneglycol (PEG) thiol ligands is reported. Comparison of commercially-available monodentate and self-synthesized bi- and tridentate methoxy terminated thiol-polyethyleneglycol…
Two graphene nanoribbons with atomically precise N-doping zigzag edges from bottom-up fabrication by a condensation reaction exhibited intrinsically magnetic properties with a maximum magnetization of 0.303 emu g <sup>−1</sup> .
Mixtures of different benzoxazine resins and elemental sulfur ( <bold>S8</bold> ) are prepared and then reacted at 120 °C, below the temperature for radical formation of sulfur, triggering the reduction of the polymerization temperature.
Two-dimensional polymers are of great interest for many potential applications in nanotechnology. The preparation of crystalline 2D polymers with a tunable band gap is critical for their applications in nano-electronics and optoelectronics. In this work, we try to tune the band gap of 2D imine polymers by expanding th…
Recent developments in molecular surface engineering inside the confined space of porous materials are surveyed including a new nomenclature proposal.
Robust stalagmite-like self-cleaning surfaces with good transparency and flexibility are developed by plasma-assisted nanofabrication and silanization under ambient conditions.
A novel isopentatungstate-supported metal carbonyl derivative KH[(CH3)4N]3{[Re(CO)3]4[(μ2-OH)(μ3-O)(W5O18)]}·6H2O () has been synthesized and characterized. Compound represents the second example of isopolyoxotungstate-supported metal carbonyl derivative. The catalysis of for alkene epoxidation with H2O2 was investiga…
We investigated heat transfer in a channel with a triangular cross-section. The working medium is a helium–xenon mixture with a low Prandtl number. This channel configuration corresponds to one of possible cases of fuel cells layout in a gas-cooled nuclear reactor. New experimental data on heat transfer in helium–xeno…
