Herein we present a simple method to coat a porous SiO2 layer on carbon nanotubes (CNTs) with the aid of the cationic surfactant cetyltrimethyl ammonium bromide (CTAB). The coating process was studied systematically, and a possible coating mechanism was proposed. Temperature and the ratio of CTAB/CNTs/H2O were found t…
The performance of solid oxide fuel cells (SOFCs) with thin film electrolytes and electrodes was investigated at a lower operating temperature regime . anode-supported unit cells with thin film components of a Ni–yttria-stabilized zirconia (YSZ) composite anode interlayer, a thin YSZ electrolyte, and a lanthanum stron…
Carboxymethyl cellulose (CMC) is one of the important cellulose derivativ es in industries, which is widely used as anti-caking agent, emulsifier , stabilizer, dispersing agent, thickener, and gelling agent. The main raw material of cellulose derivative is cellulose from wood and cotton linter. However, deforestation…
The synthesis and characterisation of a large family of trimetallic [Mn(III)(3)] Single-Molecule Magnets is presented. The complexes reported can be divided into three categories with general formulae (type 1) [Mn(III)(3)O(R-sao)(3)(X)(sol)(3-4)] (where R = H, Me, (t)Bu; X = (-)O(2)CR (R = H, Me, Ph etc); sol = py and…
Poly (hydroxyalkanoates) (PHAs) have recently attracted a great deal of academic and industrial interest for their biodegradability and biocompatibility making them suitable for environmental and biomedical applications. Poly(3-hydroxybutyrate-) (PHB-) and Poly(DL-lactide-co-glycolide) (PLGA-) based nanoparticles were…
The present work depicts the efficient one-step synthesis and detailed evaluation of stable aqueous colloids of silver nanoparticles (NPs) coated with poly(ethylene glycol) (PEG) covalently attached to their surface. Due to steric repulsion between polymer-modified surfaces, the stability of the nanoparticle suspensio…
The desire for ever smarter systems-on-a-chip and plug-free portable electronics with longer operating times between recharge has stimulated growing interest in micro-ionic systems. The use of thin film and photolithographic processing techniques, commonly at temperatures considerably below those utilized in conventio…
Boehmite (γ-AlOOH) nanocrystals with varying morphologies were synthesized by hydrothermal treatment of the freshly precipitated Al(OH)3 gel at 240 °C for 16 h in different solutions. Under acidic conditions (initial pH 4.0), boehmite nanorods with an aspect ratio of about 2 and 4, respectively, were formed in the pre…
To explore oxygen permeable materials, oxygen permeation properties of partially A-site substituted perovskites were investigated. Ba sites in were substituted with cations such as Na, Rb, Ca, Y, and La by 5%. The partial substitution with Ca, Y, and La, whose ionic radii are smaller than that of Ba, succeeded in stab…
It is demonstrated that β-Co(OH)2 has a high discharge capacity and good high-rate discharge ability as a negative electrode material. A new rechargeable battery system with higher energy density, consisting of α-phase nickel hydroxides as the positive electrode material and β-cobalt hydroxides as the negative electro…
A ferroelectric inorganic–organic hybrid based on in situ substituted stilbazolium cation (TAMS2+ = trimethylamino-N-methyl stilbazolium) has been obtained. Single-crystal X-ray structure analysis demonstrates that the NLO-phore organic component of the complex is embedded into the inorganic polymeric [Bi2Cl8]2− frame…
The interactions of charge stabilised gold nanoparticles with cationic and anionic dyes are reported. The nanoparticles were synthesised by the Turkevich citrate reduction method. It was found that when a solution of thiazine dye is titrated against gold citrate hydrosol, at a critical concentration of dye there is an…
Hexagonally packed water droplets condensed on a polymer solution are potential templates for the formation of honeycomb-patterned porous polymer films. A small number of surface-active molecules is indispensable for the stabilization of water droplets during solvent evaporation. Biocompatible surfactants; e.g., phosp…
The ability to develop a rational basis for the binding of inorganic materials to specific binding sites within self-assembling biological scaffolds has important applications in nanobiotechnology. Amyloid-forming peptides are a class of such scaffolds and show enormous potential as templates for the fabrication of lo…
A new synthesis procedure is presented to prepare P6m ordered mesoporous silica at room temperature and quasi-neutral pH in a buffered medium using a cheap silicon source.
The first reports of polymer-clay nanocomposites sprang out of industrial research from the motor industry in 1987. Since then, academic research has flourished and far outstrips industrial implementation of these new materials; approximately 700 papers were published in 2007. Much of this work, although it emphasises…
Structure, electronic properties, optical absorption and charging properties of methylthiolate-protected bimetal PdAu24(SR)18z (R = Me) clusters with various charge states (−3 ≤z≤ +3) are investigated by using density functional theory. The results are compared to properties of the well-understood singly anionic pure…
The influence of solvent on the electrochemical property and conductivity of PEDOT has been investigated by electrochemical and physical characterizations. The PEDOT treated with different solvents reveals a different reversibility of ionic transport and cycling stability, which is associated with the conformational r…
Various stakeholders have acknowledged that uncertainty within determining the potential environmental, health and safety (EHS) risks of nanomaterials (NM) may inhibit nanotechnology from reaching its full potential. A thorough description of such uncertainties is an imperative first step towards closing knowledge gap…
Nanostructured thin films of cellulose nanowhiskers derived from cotton were formed using a simple drop-coating procedure. The hydrogen-bonded cellulose films were stable in aqueous solutions and their permselective properties were probed using voltammetric techniques. The nanowhisker extraction procedure produces cel…
