Photonics and fracture toughness of heterogeneous composite materials
(
Nature Publishing Group
, 2017 , Article)
Fracture toughness measures the resistance of a material to fracture. This fundamental property is used in diverse engineering designs including mechanical, civil, materials, electronics and chemical engineering applications. ...
Investigation of the morphology and properties of the polypropylene/low-density polyethylene/wood powder and the maleic anhydride grafted polypropylene/low-density polyethylene/wood powder polymer blend composites
(
SAGE Publications Ltd
, 2017 , Article)
The properties of polypropylene/low-density polyethylene and maleic anhydride grafted polypropylene/low-density polyethylene blends, and their wood powder composites are compared in this study. The blends contained equal ...
Prediction of infarction volume and infarction growth rate in acute ischemic stroke
(
Nature Publishing Group
, 2017 , Article)
The prediction of infarction volume after stroke onset depends on the shape of the growth dynamics of the infarction. To understand growth patterns that predict lesion volume changes, we studied currently available models ...
Improving influenza vaccination rate among primary healthcareworkers in Qatar
(
MDPI AG
, 2017 , Article)
The purpose of this study was to improve influenza vaccination, and determine factors influencing vaccine declination among health care workers (HCW) in Qatar. We launched an influenza vaccination campaign to vaccinate ...

Copper is one of the most valuable and prevalent metals used in the industry. There are many techniques to treat different types of industrial wastewater that are contaminated with heavy metals such as copper. This article ...
Using B4C nanoparticles to enhance thermal and mechanical response of aluminum
(
MDPI AG
, 2017 , Article)
In this work, Al-B4C nanocomposites were produced by microwave sintering and followed by hot extrusion processes. The influence of ceramic reinforcement (B4C) nanoparticles on the physical, microstructural, mechanical, and ...
Characterizing biaxially stretched polypropylene/graphene nanoplatelet composites
(
International Committee on Composite Materials
, 2017 , Conference Paper)
During moulding processes such as thermoforming and blow moulding, heated polymer materials are subjected to rapid biaxial deformation as they are drawn into the shape of a mould. It is therefore essential to accurately ...
