have been identified as intermediates during the sequence. Detailed energy diagrams illustrate the sequence and rate constants of the photophysical events occurring with the mechanically-linked chromophores. This work pioneers the exploration of mechanically-linked systems as platforms to position three distinct chrom…
Based on the important effect of catalyst on the plasma-catalytic system, various types of zeolites (5A, HZSM-5, Hβ, HY and Ag/HY) were chosen as catalysts to remove toluene under non-thermal plasma conditions in this work.
Branched α-MnO 2 nanorods are synthesized using a facile, green and effective one-pot hydrothermal approach without surfactants or templates. The branched α-MnO 2 nanorod electrode exhibited good supercapacitive properties due to its novel textural morphology and crystal structure.
Bacterial cellulose (BC) can be used in wide area of applied scientific, especially for tissue regeneration and regenerative medicine, lately, bacterial cellulose mats are used in the treatment of skin conditions such as burns and ulcers, because of the morphology of fibrous biopolymers serving as a support for cell p…
Response surface methodology was used to optimize preparation of biocomposites based on poly(lactic acid) and durian peel cellulose. The effects of cellulose loading, mixing temperature, and mixing time on tensile strength and impact strength were investigated. A central composite design was employed to determine the…
In this paper, graphene oxide (GO) was prepared by the Hummers' method and reduced using hydrazine to produce graphene nanosheets (GNS). Physicochemical characterizations of the prepared materials were performed using XRD, FTIR, TGA, DTA, BET, UV-vis, Raman, and FESEM techniques. The results elucidate the structure, m…
Nowadays, waste tires bring the world increasing environmental and economic issues. Although pyrolysis seems to be a feasible process, a proper application of generated residues needs to be solved urgently. In this work, activated carbons (ACs) derived from the industrial pyrolytic tire char were first evaluated as po…
The present investigation deals with formulation of nicotinamide-based co-crystals of fenofibrate by different methods and solid-state characterization of the prepared co-crystals. Fenofibrate and nicotinamide as a coformer in 1:1 molar ratio were used to formulate molecular complexes by kneading, solution crystalliza…
The effects of soaking time during the alkaline treatment on the tensile strength of Napier grass fibre and its morphology are discussed. The fibres were treated with 10% of Sodium Hydroxide (NaOH) concentration solution at different soaking times exposure; 3, 6, 12, 18 and 24 hr. The single fibre tests were then perf…
Large enhancement of TE properties via a novel two-step post treatment.
Facile synthesis of a highly porous, light weight 3D sponge like graphene aerogel derived from graphene oxide for microwave shielding applications.
Sulfur nanoparticles (S-NPs) were prepared in this work by precipitation method using sodium thiosulphate and tetraoctylammonium bromide surfactants in conc. hydrochloric acid media. The sizes and shapes of S-NPs were confirmed by scanning electron microscope (SEM), transmission electron microscopy (TEM) and X-ray dif…
Mechanically strong and flexible graphene/polypyrrole composite films with hierarchical structures are fabricated. They demonstrate very high areal capacitances.
A silica nanospheres/graphene oxide hybrid (SGO) was synthesized, and it is found that SGO can greatly improve the mechanical strengths, thermal stability and flame retardancy of phenolic foams.
Three kinds of GO-based polymeric membranes with specific adsorption characteristics were fabricated by a facile blending method; the prepared membranes showed good adsorption capacities and selectivity for the difficult types of water contaminants.
Water absorption and thermomechanical behavior of composites based on thermoplastic starch (TPS) are presented in this work, wherein the concentration of agave bagasse fibers (ABF, 0–15 wt%) and poly(lactic acid) (PLA, 0–30 wt%) is varied. Glycerol (G) is used as starch (S) plasticizer to form TPS. Starch stands as th…
A series of phosphorus-containing polyimide–POSS nanocomposites were synthesized, phosphorus and POSS synthetic self-passivating layers were formed to protect the underlying material from AO attack.
dyes have a superior character in that their NIR optical properties can be readily tuned by the intrinsic spiro-cyclization mechanism. We expect that this "capping" strategy can be extended across not only the visual spectrum but also to structurally distinct fluorophores.
The ability to accurately and reliably detect the presence of explosives is critical in many civilian and military environments, and this is often achieved through the sensing of the vapour emitted by the explosive material. This review summarises established and recently developed detection techniques.
Aerogels have much potential in both research and industrial applications due to their high surface area, low density, and fine pore size distribution. Here we report a thorough structural study of three-dimensional aerogels composed of highly crystalline sp(2)-bonded boron nitride (BN) layers synthesized by a carboth…
