Au nanostructures attract much attention due to their potential applications in many fields. The controlled synthesis is critical to their properties modulation and applications. AgNO3-assisted synthesis is a widely used method for controllably preparing Au nanostructures in aqueous system. Herein, the effect of AgNO3…
Benzoin, a common reagent, has been used as a reducing agent for large scale production of reduced graphene oxide nanosheets and also for a gold-reduced graphene oxide nanocomposite (Au–rGO) by a co-reduction method. The pH of the reaction medium plays a crucial role in controlling the reaction kinetics. Systematic mi…
The synthesis of supported bimetal oxide nanoparticles for catalytic applications has greatly suffered from the strong phase separation trend and particle aggregation problem. We found that just adding facile pre-drying treatment before the calcination step can sufficiently avoid the phase separation and prevent the p…
Amorphous Co–Sn alloy was co-electroplated on a three-dimensional framework of nickel foam and then CoSn2 phase was formed after annealing at 200 °C. It is observed that short electrodeposition times favour a higher x-value in the resulting CoSnx alloy. Low current densities and short electrodeposition times favour th…
An amphiphilic macrocycle based on pillar[5]arene with polar lysine head groups spontaneously self-assembles into a bimolecular micelle in water. This self-assembled structure was characterized by small angle X-ray scattering (SAXS), field flow fluctuation coupled with multi-angle light scattering (FFF-MALS) and atomi…
The electrochemical behavior of the redox couple ferro/ferricyanide has been investigated in aqueous 1.0 M KNO3 and in (w/o) microemulsion using cyclic voltammetry (CV) and chronoamperometry (CA). The (w/o) microemulsion was composed of the non-ionic surfactant Tween-80, tetrabutylammonium perchlorate (TBAP) supportin…
The impact of various polymeric compatibilizers, including end-functionalized P3HTs and diblock copolymers containing P3HT, on the structure and function of poly(3-hexylthiophene) (P3HT):[6,6]-phenyl-C61-butyric acid methyl ester (PCBM) bulk heterojunctions is presented. Careful analyses of small angle neutron scatter…
A new and one-pot protocol for mass-producable synthesis of the poly(ethylene oxide propylphosphonamidate) (PEOPPA) hydrogel bearing multi-amine and multi-amino groups with excellent swellability and flexibility has been described. The structural characterization of the formed gel was well analyzed by infrared, solid…
There is a need to develop catalysts for the direct ammoxidation of ethane to acetonitrile. This work reports a series of bulk Ni–Nb–O catalysts with increasing niobium content, analysing the structure and the effect on acidity and redox properties and how these relate to Ni–Nb interaction. Niobium doping affects NiO…
We have developed electrically driven photonic crystals (PCs) from a quaternized polystyrene-b-poly(2-vinyl pyridine) (PS-b-P2VP) block copolymer which can form a one dimensional periodic lamellar structure. The variation of applied voltage from −4.50 to +2.36 V on the PCs can lead to color display over the entire vis…
Perovskite structure oxygen carriers with the general formula CaMnxMg1-xO3-δwere spray-dried and examined in a batch fluidized bed reactor. The CLOU behavior, reactivity towards methane, and syngas were investigated at temperature 900°C to 1050°C. All particles showed CLOU behavior at these temperatures. For experimen…
Transparent conductive oxide layers (TCO) are used as electrodes for thin film applications. The optical performance of TCOs can be improved by implementing textured surfaces that will increase the overall transmission of light through the TCO layer. In this paper, a model is developed using Synopsys TCAD to accuratel…
We show a new approach to control the self-assembly of paddle-wheel dimers by intermolecular multipoint arene–perfluoroarene interactions. Two types of complexes, I-shaped Rh2(O2CCF3)2(L)2(3-pentanone)2 (1) and cross-shaped Cu2(L)4(THF)2 (2) were synthesized to afford 1D chain and 2D square-grid sheet structures, resp…
The results of an experimental investigation of the mechanical properties of fly ash and Alumina reinforced aluminium alloy (LM25) composites samples, processed by stir casting route are reported in this paper. Three sets of composites with constant weight fraction of fly ash (particle size of 3-100 m) and Al2O3(parti…
This book chapter discusses the syntheses of various nanomaterials, for green nanotechnology applications in detail. Special attention is given to the development of emerging areas, such as environmental as well as energy materials. Various approaches for preparing nanostructured photocatalysts, such as titanium dioxi…
The Gram-positive coccus, Staphylococcus aureus, is the leading etiologic agent of limb and life-threatening biofilm-related infections in the patients following the orthopaedic implantations. The aim of the present paper is to estimate the ability of S. aureus to form biofilm on titanium alloy (Ti-6Al-7Nb) scaffolds…

Direct conversion of methane to other valuable products such as ethylene, methanol, benzene, carbon, hydrogen, and syngas has been widely investigated. Such conversion requires high temperatures because of the strong C–H bond in CH4, and such high-temperature reactions present various problems: sequential reaction to…
Zero bandgap and water soluble sulfonated graphene (SGE) has been introduced into an n-type semiconductor photocatalytic system to fabricate a Ag@AgBr/SGE composite photocatalyst. Due to its unique conduction and valence band dispersion and low Fermi level, SGE serves as an electron reservoir within the photocatalyst…
For many centuries bulking agents in composting has been used for better and improved compost production. In recent years bulking agents or bulking particles received much attention because of efficiency and usefulness in composting, pollution control and economically sound. The industrial and agricultural waste manag…
