Electrodeposition is a simple and economic technique for precision coating of different shaped substrates with pure metal, alloy or composite films. Dc electrodeposition was used to produce Cr, Co-Cr and Co-Cr/TiO2 nano-composite coatings from Cr(III) based electrolytes onto 316L SS substrates. The effects of TiO2 nanoparticles concentration on co-deposition of these particles along with Cr con...

STATEMENT OF THE PROBLEM The adhesion of resin-modified glass-ionomer (RMGI) to composite resin has a very important role in the durability of sandwich restorations. Hydroxyapatite is an excellent candidate as a filler material for improving the mechanical properties of glass ionomer cement. PURPOSE The aim of this study was to assess the effect of adding micro- and nano-hydroxyapatite (HA) p...

Isolated Escherichia coli K-12 cell envelopes or Bacillus subtilis 168 cell walls were reacted with smectite or kaolinite clay in distilled deionized water (pH 6.0); unbound envelopes or walls were separated by sucrose density gradient centrifugation, and the extent of adsorption was calculated. At saturation, both clays adsorbed approximately 1.0 mg (dry weight) of envelopes or walls per mg (d...

This article presents a novel method for tuning the reactivity of nanoenergetic materials by coating a strong oxidizer nanoparticle (potassium permanganate; approximately 150 nm) with a layer of a relatively mild oxidizer (iron oxide). The measured reactivity for a nano-Al/composite oxidizer could be varied by more than a factor of 10, as measured by the pressurization rate in a closed vessel (...

The usage of clay polymer composites has increased in the past few decades. Due to extensive availability, wide surface areas, and good adsorption efficiency polymers are gaining popularity amongst researchers remove range organic as well inorganic pollutants from effluents. This book chapter sheds light on characteristics, occurrence, types synthesis minerals used for preparing nano-clay compo...

−− A composite coating from Amaranthus cruentus flour and stearic acid (10 g stearic acid/100 g flour, 26 g glycerol/100 g flour and stirring speed at 12000 rpm) was applied on fresh strawberries in order to verify the effect on its quality. Other treatments were effected to comparison: PVC film, bilayer coating of the optimized formulation, optimized formulation without stearic acid and a cont...

NieS/CeO2 electrodes have been prepared by a composite electrodeposition technique using nickel sulfaminate bath containing suspended microor nano-sized CeO2 particles. The composite electrodes exhibit a high activity for the hydrogen evolution reaction (HER) in alkaline solutions, most likely due to the synergistic effects between Ni and CeO2, as well as the increased surface area of the elect...

One of the newest technologies for storing agricultural products is the biodegradable packagingmethod, in which certain materials are utilized on a nano scale. Edible mushroom is a nutritious agriculturalproduct which can be considered a food source as well as having medicinal applications while having a shortshelf life after harvesting. In this study, the mushroom was packaged in polylactic ac...

Embedded capacitor technology can improve electrical performance and reduce assembly cost compared with traditional discrete capacitor technology. Polymer–ceramic composites have been of great interest as embedded capacitor material because they combine the processability of polymers with the desired electrical properties of ceramics. A novel nano-structure polymer–ceramic composite with very h...
