We developed a facile one-step route for the synthesis of blue fluorescent OS-GCNQDs, which exhibited improved selectivity and sensitivity for Hg <sup>2+</sup> detection, and lower cytotoxicity for cell imaging.
Improving the photochemical properties of molecular photoswitches is crucial for the development of light-responsive systems in materials and life sciences. ortho-Fluoroazobenzenes are a new class of rationally designed photochromic azo compounds with optimized properties, such as the ability to isomerize with visible…
A new self-healing multiphase polymer is developed in which a pervasive network of dynamic metal-ligand (zinc-imidazole) interactions are programmed in the soft matrix of a hard/soft two-phase brush copolymer system. The mechanical and dynamic properties of the materials can be tuned by varying a number of molecular p…
AIM: 1 document the spectrum of ocular toxicity of calotropis procera, its complications, prevention and management. 2 Make aware or educate the field workers about the toxic effects of calotropis procera latex.METHODS: A retrospective study of 25 patients those presented with accidental ocular contact or injury with…
Graphene is theoretically expected to be a highly suitable material for spintronic and quantum computation applications. Current experimental reports assign surprisingly low spin lifetimes to graphene and related carbon structures. Recently, we showed a solvothermal synthesis method that can be employed to produce a h…
There are three main categories of marine collagens: collagens of invertebrate origin (sponges, jellyfish, molluscs), fish collagens, and marine mammal collagens. Marine fish collagens isolated from skin, meat, scales, fins and waste materials are of particular interest from an industrial point of view. Different type…
A quaternary ammonium surfactant (S) carrying a phenol terminal was grafted on the surface of nano-sized polyoxometalates, H4SiW12O40 (PM-1), K6P2W18O62 (PM-2) and Na10[Co4(H2O)2(VW9O34)2] (PM-3), respectively, by ionic self-assembly. The obtained complexes were connected with the poly(vinylpyridine) (P4VP) backbone v…
Reaction pathways have been determined for the formation of two thermoelectric materials, bismuth telluride and lead telluride, fabricated by solution-phase, solid-state synthesis. The fabrication of these compounds by way of a modified polyol process has been investigated because this bottom-up approach has a procliv…
Low-temperature induced diffusive to ballistic transport in aligned double walled carbon nanotubes (DWNT) is reported. This is evidenced by a crossover of the imaginary (reactive) component of the alternating current impedance being greater than the real (resistive) component, which happens in the range of 9 GHz–1.5 G…
Large area and uniform nanosheets Co 3 O 4 have been fabricated by thermal annealing of cobalt thin film under the DC magnetron sputtering method. The synthesis is based on controlling the simple thermal oxidative formation of precursor Co films. The Co films were heated at 300, 400, and 500 °C for two hours in a pure…
Instant research project was an attempt to address the postharvest losses in strawberry using the concept of biodegradable edible coatings. Purposely, alginate and soy based coatings were developed at various levels (2, 2.5 and 3%) and assessed for the role in controlling the moisture loss and total solids in the coat…
The paper describes results of a theoretical study of the electronic structure of the capped finite-length single-walled carbon nanotube (5, 5) under an applied electric field in the range from 0 to 0.5 V/Å. Clear oscillations of an ionization potential, electron affinity, gap energy and an effective work function on…
ZnO nanorods produced hydrothermally, using different precursor concentrations, show strikingly different morphologies and photoluminescence properties after encapsulation in silica. These differences are traced to differences in the nanorod growth chemistry.
We report the terahertz photoconductivity in a meander-shaped epitaxial graphene sample. The measurements at wavelengths 280, 148, and 90 μm (frequencies of 1.07, 2.03, and 3.32 THz) demonstrate that the photoconductivity is independent on the wavelength and is related to bolometric heating under the condition of weak…
A family of paramagnetic cyanido-bridged 1-D heteronuclear zigzag chain isostructural complexes, [cis-M(bpy)2(CN)2Mn(salen)](PF6) (M = Fe, 1; M = Ru, 2; M = Os, 3; bpy = 2,2′-bipyridine, salen = N,N′-ethylenebis(salicylideneaminato)dianion) and [cis-Os(bpy)2(CN)2Mn(salcy)](PF6) (4) (salcy = N,N′-(1,2-cyclohexanediylet…
The purpose of this research is to establish a processing method for a wide-area nanometer scale periodic structure on the surface of a plastic plate in order to improve its hydrophobicity. We also evaluated the effect of a nanoperiodic structure applied in the uniaxial direction. Plastic plates of acrylonitrile–ethyl…
A series of novel vegetable oil‐based interpenetrating polymer networks (IPNs) have been successfully prepared: on one hand, methacrylated camelina oil (MCO) and a polyethyleneglycol dimethacrylate (PEG, MW 750 g/mol) and on the other hand, diglycidylether of bisphenol A (DER), in various blend ratios (75/25, 50/50, a…
Using differential scanning calorimetry, we show that the addition of solute(s) to emulsified water lowers the freezing temperature to <231 K, the homogeneous nucleation temperature of pure bulk water, or even completely suppresses freezing. In the latter case, freezing upon warming occurs above T(X) ≈ 150 K and leads…
Surface treatment of cellulose fibers was performed with maleated high oleic sunflower oil (MSOHO). The MSOHO‐treated cellulose fibers and unmodified cellulose fibers were dispersed in styrene butadiene rubber (SBR) using a two roll mill. Vapor grown carbon nanofibers (VGCNF) were also incorporated at only one parts p…
ZnO nanorod arrays have been synthesized on silicon wafers by catalyst free thermal vapor deposition with different temperature values. Vertical-aligned ZnO nanostructures were grown at the quite low temperatures by this method. Modification of the method allowed to place silicon substrates in areas with different rat…
