Reduction in HDPE geomembrane thermal expansion using nanoclay particles

Dolez P.I., Mohamed R., David É., Weltrowski M., CTT Group, CA

Polymer membranes have progressively replaced traditional building materials to perform waterproofing functions and control the advective migration of pollutants in civil engineering structures. Either during deployment or in service, geomembranes, 50% of which being made [...]

Nanofiller-modified microfibrillar composites: origin of complex effect of nanoparticles with different geometry

Kelnar I., Kratochvíl J., Padovec Z., Institute of Macromolecular Chemistry, Academy of Sciences of the Czech Republic, CZ

Microfibrillar composites (MFCs) are polymer – polymer composites prepared by drawing of suitable polymer blends, where application of various nanofillers have strong potential to eliminate basic disadvantage of MFC arising from limited parameters of polymer [...]

Glass-Ceramic Scintillators for High-Resolution Medical Imaging

Beckert M.B., Nadler J.H., Kang Z., Wagner B.K., Georgia Tech Research Institute, US

Screens made from micron-sized phosphor particles (such as Gd2O2S:Tb) are efficient and bright X-ray converters used in medical imaging systems. However, the large size of the phosphor particles causes the screen to be opaque and, [...]

Electrophoretic Coating of Hydroxyapatite-Boron Nitride Nanocomposites on Titanium Implants

Bakan F., Sezen M., Goncu Y., Ay N., Sabanci University, TR

Titanium (Ti) and its alloys have long been used as implant materials in dental and orthopedic applications. However, they can suffer certain disadvantages, such as poor osteoinductive properties and low corrosive-wear resistance. The potential of [...]

Improving the sensitivity of Pedot:Pss modified gold electrode using gold and silver nanoparticles for Ganoderma boninense DNA detection

Dutse S.W., Yusof N.A., Ahmad H., Hussaini Adamu Federal Polytechnic, NG

The sensitivity of a designed electrochemical DNA biosensor was improved using gold and or silver nanoparticles. A gold electrode modified with a conductive nanocomposite of poly(3,4-ethylenedioxythiophen)–poly(styrenesulfonate) (Pedot-Pss) and gold or silver nanoparticles enhanced the conductivity [...]

Effect of Big-Cube Zr2Ni on the Absorption and Desorption Kinetics of Nanocrystalline MgH2 Powders

El-Eskandarany M.S., Al-Matrouk H., Al-Duweesh A., Shaban Ehab, Kuwait Institute for Scientific Research, KISR, KW

A new hydrogen storage system of nanocomposite MgH2/10 wt.% big-cube Zr2Ni nanocrystalline powders were synthesized. A -MgH2 phase coexisted with small mole fractions of -MgH2 nanocrystalline ultrafine powders were obtained after reactive ball milling (RBM) [...]
