A class of Yb3+/Er3+ ion co-doped CaLa2ZnO5 (CLZ) novel up-conversion (UC) phosphors were synthesized by a sol–gel method. The crystal structure and the phase composition of the samples were characterized by X-ray diffraction (XRD). Under 980 nm excitation, UC spectra are composed of three prominent emission bands cen…
Among new low-melting-point glasses, bismuth ate glass is deemed to have the most potential as an environmentally friendly replacement for polluting Pb-containing glasses. Current studies of boro-bismuthate glasses focus on the structural influence of the additional oxide in the context of low-melting-point electronic…
Porous Au nanoparticles with fine-controlled overall particle sizes have been fabricated using a kinetically controlled seed-mediated growth method. In contrast to spherical Au nanoparticles with smooth surfaces, the porous Au nanoparticles exhibit far greater size-dependent plasmonic tunability and significantly inte…
A strategy for the synthesis of covalent organic frameworks with open docking sites is developed. The docking sites are ordered on the channel walls and structurally predesignable for meeting various types of noncovalent interactions, thus opening a way towards designing supramolecular materials based on crystalline p…
A multi-redox polyoxometalate-based hybrid polymer has been demonstrated to show multilevel resistive switching memory behaviors.
We have studied foams stabilised by surfactant-decorated nanoparticles adsorbed at the bubble surfaces. We show that the controlled compression of a single bubble allows one to understand the coarsening behavior of these foams. When bubbles are compressed, the particles become tightly packed in the surface layer. They…
The present study revealed the toxic effect of silver nanoparticles (AgNPs) in Artemia nauplii and evaluated the mortality rate, hatching percentage, and genotoxic effect in Artemia nauplii/cysts. The AgNPs were commercially purchased and characterized using field emission scanning electron microscope with energy disp…
Flexible all-solid-state micro-supercapacitors were fabricated by a screen printing method using N-doped reduced graphene oxide as an active material and show high specific capacitance and long cycle life.
The formation of an air-column on a superhydrophobic surface: the superhydrophobic coating is surrounded by blue colored water forming an air column, and water acquires a height of nearly 5 mm around the boundaries of the superhydrophobic coating. This confirms that the superhydrophobic surface strongly repels water a…
Novel conductive ultrathin graphene papers demonstrate effective EMI shielding of ∼46.3 dB (∼0.3 mm) and ∼47.7 dB (∼0.1 mm) in attenuators.
The presence of reactive diluent 1,4-Butandioldiglycidylether in epoxy mixtures reduces the sorption at equilibrium of liquid water (graphic on the right) and eases the step of nanofiller dispersion (figure on the left).
Simple synthesis and versatile functions: by directly reacting a triphenylene hexathiol molecule (HTT) with PtCl2, a covalent metal-organic framework (CMOF) has been prepared that features substantial porosity, redox activity and ion exchange capability.
SnTe–AgBiTe 2 is not only a solid solution but a nanocomposite. The alloying effect coupled with intense interface scattering leads to considerably decreased lattice thermal conductivity. Bi is much more powerful in neutralizing holes than Sb, giving rise to a much higher Seebeck coefficient. A high ZT was then obtain…
Metallic nanoparticles (NPs) constitute a new class of chemical objects which are used in different fields as diverse as plasmonics, optics, catalysis, or biochemistry. The atomic structure of the NP and its size usually determine the chemical reactivity but this is often masked by the presence of capping agents, solv…
We report large-scale biosynthesis of copper nanoparticles using an extract of henna leaves as reductant. Due to the substantial electrical conductivity of the calcined copper nanoparticles, we used them to prepare conductive nanobiocomposites utilizing collagen waste. We demonstrate that the nanobiocomposites, when i…
The role of natural and manmade fibers reinforced hybrid composite materials are growing in a faster rate in the field of engineering and technology due to its favorable properties. In the present unsustainable environmental condition natural fibers are serving better material in terms of biodegradability, low cost, h…
Fiber-based asymmetric micro-supercapacitor (F- asym -mSC) is assembled by core–sheath graphene fiber decorated by MnO 2 as the positive electrode and graphene-carbon nanotubes hybrid fiber as the negative electrode. The F- asym -mSC shows the highest energy density (11.9 μWh cm −2 ) for fiber-based supercapacitors an…
Silver colloidal nanoparticles were prepared according to the chemical reduction method in which the ascorbic acid was used as a reducing agent and sodium citrate as a stabilizing agent. The absorption spectra of all prepared samples obtained using the UV-Vis spectrophotometer showed a surface plasmon peak at a wavele…
Nanomaterials, with their size range (1-100 nm) that corresponds to basic biological materials such as DNA, vastly increased surface area (1000 m 2 /g) and unique mechanical, electronic, photonic and magnetic properties are projected to have a wide range of applications from drug and gene delivery to biomedical imagin…
