The microstructure, mechanical and dry-sliding tribological properties of TiAl-based composites with 20 and 40 vol% in situ formed Ti2AlC, produced by hot press sintering process, are investigated. The microstructural characterization reveals that Ti2AlC phase is in the form of spherical particles and large blocks, an…
Nanomedicine is an emerging and novel field that wi ll not only change the way veterinary medicine is practiced but also revolutionize the modern day therapeutics and diagnosis of diseases. It is the application of nanotechnology to achieve faster and effective solu tion to our day to day problems of management of dis…
Green synthesis of nanoparticles using plant extract is the novel method to develop environmentally being nanoparticles which can be used in numerous biomedical applications. In this study we have synthesized TiO2 nanoparticles from Titanium Oxysulfate solution using Hibiscus flower extract. The synthesized nanopartic…
The optical spectra of oriented SmFe3(BO3)4 single crystals are studied in the region of the f-f transitions in the Sm3+ ion by Fourier spectroscopy. The energies, the symmetry properties, and the exchange splittings of the Stark sublevels of the ground and 17 excited multiplets of the Sm3+ ion in a crystal field of s…
Caloropis procera is a multipurpose plant that is extensively used by traditional folk healers and local people for preparation of different drugs and ailments of choice to treat different diseases and disorders. Plant contains diverse phyto‑chemicals which show various pharmaceutical and ethno‑medicinal properties. T…
Chitosan has been produced from shrimp waste by chemical method involving demineralization, deproteinization and deacetylation. The quality of chitosan depends on the conditions of the chemical extraction process. The results showed that 3% HCI and 4% NaOH were suitable concentration for demineralization and deprotein…
Nano science and nanotechnology are new frontiers of this century and food nanotechnology is an emerging technology. Food nanotechnology is an area of emerging interest and opens up a whole universe of new possibilities for the food industry. In food engineering, two major applications related to nanotechnology (i.e)…
Emerging infectious diseases and the increase in incidence of drug resistance among pathogenic bacteria have made the search for new antimicrobials inevitable. In the current situation, one of the promising and novel therapeutic agents could be the nanoparticles. In this study, antimicrobial susceptibility testing of…
The solid state reactions of BaTiO3 formation from a mechanically activated BaCO3-TiO2 powder mixture have been investigated. Thermogravimetric TGA, thermomechanical TMA, scanning electron microscopy SEM, X-ray diffraction XRD and reactions thermodynamic analyses have been used in the present study. The results of the…

A supramolecular polymer gel was prepared from self-assembly of a heteroditopic A–B monomer based on benzo[18]crown-6. Such a gel shows interesting gel–sol transitions in response to dual-stimuli owing to the dynamically reversible complexation between benzo[18]crown-6 and primary alkylammonium salt moieties.
By means of limiting oxygen index (LOI), cone calorimeter, and TG-DSC tests, this paper investigated the effect of unmodified montmorillonite (MMT), organically modified montmorillonite (OMMT), and aluminium trihydrate (ATH) additions on the flame retardancy for asphalt combustion. Experimental results showed that add…
We report the properties of glycoconjugated porphyrin dimers behaving as highly sensitive ratiometric temperature sensors in water. This effect results from interactions between carbohydrate and water altering molecular relaxation kinetics leading to temperature sensitive dual emission. These dimers are robust ratiome…
We applied AIEE to the visualization of crystal formation processes. We found that J-aggregates act as precursors for crystal nuclei, and that the growth from J-aggregates to crystal nuclei is the rate-determining step in the nucleation process.
A new method for facile fabrication of high refractive index materials that is based on simple blending of polymers and heteropoly acids is demonstrated. This hybridization is shown to dramatically increase the refractive index of the general polymer, while maintaining a high transparency.
Using transformation electromagnetics concept, we introduce an approach to virtually delocalize radiating sources and to transform their radiation pattern at the same time. We propose the design of an electromagnetic device that can virtually change the location of the emission point. By applying radial transformation…
Mullite fibres/whiskers frameworks (MF/MW frameworks) were prepared by mixed-slurry-filtration and heat-treating. Hierarchical fibres/whiskers structure formed in the frameworks through fluorine-catalyzed gas-phase reaction. Topaz rods as a transient product first formed in the frameworks, and then gradually transform…
The synthesis and gelation properties of a structurally simple, renewable-resource-based glucose-triazole-hydrogenated cardanol conjugate (GTHCC) are reported. The conjugation of hydrogenated cardanol and glucose was done using a triazole linker employing copper(I) mediated acetylene azide cycloaddition ‘click’ chemis…
The facile and efficient InCl <sub>3</sub> /2-iodophenol-catalyzed polycyclotrimerization of diynes to generate regioregular hyperbranched polyarylenes was successfully established.
Novel hybrid nanocomposites of Cu2O nanoparticles (NPs) partially embedded in CuO nanowires (NWs) were produced by simple thermal reduction of CuO NWs in a vacuum. It is found that most Cu2O NPs adopt two regular shapes, one being cubic and the other being octahedral. The shape selection of the Cu2O nanocrystals is go…
