Role of ultrasound in the management of diabetes in pregnancy
(
Taylor and Francis Ltd.
, 2015 , Article)
The purpose of this review is to discuss the established role of ultrasound (US) in the management of pregnancy complicated by diabetes mellitus (DM), as well as new developments with regard to the use of US in this ...
Synoptic analysis of direct contact membrane distillation performance in Qatar: A case study
(
Elsevier B.V.
, 2015 , Article)
The aim of this study is to evaluate a bench scale direct contact membrane distillation (DCMD) performance using flat sheet polytetrafluoroethylene (PTFE) membrane at different inlet flow rates, temperatures, and salinity ...
Mucoadhesive chitosan derivatives as novel drug carriers
(
Bentham Science Publishers B.V.
, 2015 , Article)
Chitosan on its own is a well-established natural polymer and is widely regarded as a biodegradable, biocompatible and nontoxic material for drug delivery applications. Although unmodified chitosan has some mucoadhesive ...
Porcine cholecyst derived extracellular matrix (p-CEM) for reconstruction of full thickness skin wounds in rats
(
Elsevier GmbH
, 2015 , Article)
An acellular cholecyst derived extracellular matrix (p-CEM) of porcine origin was prepared using anionic biological detergent. Healing potential of (p-CEM) was compared with commercially available collagen sheet (b-CS) and ...
Binary blend based dye sensitized photo sensor using PCPDTBT and MEH-PPV composite as a light sensitizer
(
Elsevier Ltd
, 2015 , Article)
In this research, we present a binary blend of two polymers, i.e., namely, poly[2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclopenta [2,1-b;3,4-b′]dithiophene)-alt-4,7(2,1,3-benzothiadiazole)] (PCPDTBT) and poly[2-methoxy-5-(2-ethy ...
Ultrahigh Aspect Ratio Copper-Nanowire-Based Hybrid Transparent Conductive Electrodes with PEDOT:PSS and Reduced Graphene Oxide Exhibiting Reduced Surface Roughness and Improved Stability
(
American Chemical Society
, 2015 , Article)
Copper nanowires (CuNWs) with ultrahigh aspect ratio are synthesized with a solution process and spray-coated onto select substrates to fabricate transparent conductive electrodes (TCEs). Different annealing methods are ...
Effect of expanded graphite on the phase change materials of high density polyethylene/wax blends
(
Elsevier
, 2015 , Article)
Phase change materials fabricated from high density polyethylene (HDPE) blended with 40 or 50 wt% commercial wax (melting point of 43.08�C) and up to 15 wt% expanded graphite (EG) were studied. Techniques including scanning ...
Graphene and graphitic derivative filled polymer composites as potential sensors
(
Royal Society of Chemistry
, 2015 , Article)
Graphite and numerous graphitic-derived micro- and nano-particles have gained importance in current materials science research. These two-dimensional sheets of sp2-hybridized carbon atoms remarkably influence the properties ...
Nanomechanical properties of plasma treated polylactic acid
(
Maney Publishing
, 2015 , Article)
In this work, a radio frequency discharged plasma generated in air atmosphere by pressure has been used to modify polylactic acid (PLA) surface. The results were evaluated through nanoindentation testing. Contact angle ...
Human gait recognition with cane assistive device using quadratic time-frequency distributions
(
Institution of Engineering and Technology
, 2015 , Article)
In this study, the authors consider the problem of human gait recognition in the presence of a walking cane using radars. Quadratic time-frequency distributions are used to provide the local signal behaviour over frequency ...
