We propose the design, simulation, and measurement of a broadband reflective metamaterial polarization rotator in the microwave region based on multiple plasmon resonances. An utra-thin wideband polarization conversion composing of arrays of oval ring pattern, a dielectric layer and a continuous metallic layer is furt…
Novel bioresin epoxy methyl soyate was synthesized by transesterification process and subsequently used as reactive diluent for toughening of epoxy.
We report a new light-responsive and self-healing anticorrosion coating by incorporating hollow nanocontainers with smart molecular switches.
Here we report the first example of an isolable, ambient stable perylene bisimide (PBI) dianion which was synthesized by catalytic reduction of a highly electron deficient PBI derivative. The remarkable stability of this unprecedented dianion in air for months facilitated its complete characterization by different met…
Research on graphene-monolayers of carbon atoms arranged in a honeycomb lattice-is proceeding at a relentless pace as scientists of both experimental and theoretical bents seek to explore and exploit its superlative attributes, including giant intrinsic charge mobility, record-setting thermal conductivity, and high fr…
In this work, chemical expansion in perovskite oxides was characterized in detail, motivated, inter alia, by a desire to understand the lower chemical expansion coefficients observed for perovskites in comparison to fluorite-structured oxides. Changes in lattice parameter and in local atomic arrangements taking place…
In this work, for the first time, magnetic MOFs were synthesized as carriers for enzyme immobilization. The magnetic MOF-enzyme composites exhibited significantly improved digestion performance, excellent reusability, stability and reproducibility for different kinds of enzymes.
A supramolecular gel formed by coordination of Zn(2+) with adenosine monophosphate (AMP) is reported. The adenine base, the monophosphate, and Zn(2+) are all important for gel formation. Mechanically disrupted gels can re-form upon centrifugation; applications of this gel for guest-molecule entrapment are explored.
The effects of interlayer lone-pair interactions on the electronic structure of SnO are explored using density-functional theory. Our comprehensive study reveals that the band gap of SnO opens with the increase in the interlayer Sn-Sn distance. The effect is rationalized by the character of band edges which consist of…
A meso-microporous carbon was prepared by the combination of a template method and chemical activation with earth abundant cellulose and lignosulphonate as the sources..
Using first-principles density functional theory calculations, we investigate the geometries, electronic structures, and thermodynamic stabilities of substitutionally doped phosphorene sheets with group III, IV, V, and VI elements. We find that the electronic properties of phosphorene are drastically modified by the n…
The adsorption of water and deuterium oxide on TiO2 surfaces was investigated in the dark as well as under UV(A) irradiation using in situ ATR-FTIR spectroscopy under oxygen and oxygen free conditions. Adsorption of H2O-D2O mixtures revealed an isotopic exchange reaction occurring onto the surface of TiO2 in the dark.…
As for selective CO methanation over heterogeneous catalysts, numerous investigations of the reaction mechanism and catalyst development are reviewed.
The fabrication of novel hierarchical graphene@Fe3O4 nanocluster@carbon@MnO2 nanosheet array composites has been successfully carried out for the first time. The fabrication process involves the deposition of Fe3O4 nanoclusters on graphene's surface using a simple in situ hydrothermal method, subsequent introduction o…
Highly-flexible thermoelectric fabrics were fabricated based on a layered structure, composed of a thin active layer of self-assembled tellurium nanorods and a substrate layer of polyvinylidene fluoride. The resulting thermoelectric fabrics show a high room temperature power factor of 45.8 μW m(-1) K(-2), which opens…
An ideal vascular substitute, especially in <6 mm diameter applications, is a major clinical essentiality in blood vessel replacement surgery. Blood vessels are structurally complex and functionally dynamic tissue, with minimal regeneration potential. These have composite extracellular matrix (ECM) and arrangement. Th…
Here, a hybrid material of sandwiched reduced graphene oxide (rGO) and N,S co-doped carbon quantum dots (N,S-CQDs) was prepared following a facile synthetic route.
NaYF 4 :Yb:Er nanoparticles (UCNP) were synthesized under mild experimental conditions to obtain a pure cubic lattice. Upon annealing at different temperatures up to T an = 700 °C phase transitions between hexagonal phase and the cubic phase were induced. Based on the TRANES analysis it was possible to resolve the lat…
The hybrid filler network of GE/CNTs dissipates energy upon deformation and this leads to remarkable toughening and reinforcing effects on rubbers.
Ab initio hybrid DFT theory of graphene dots in graphene oxide predicts optically active energy gaps over visible and UV spectra with strong absorption characteristics and long radiative recombination times.
