Improvement of humidity sensing properties of PVDF-TiO2 nanocomposite films using acetone etching
(
Elsevier B.V.
, 2019 , Article)
In this work, we enhanced the humidity sensing properties of the polyvinylidene fluoride titanium dioxide (PVDF-TiO2) nanocomposites based capacitive humidity sensors by modifying the film surface. The surface morphology ...
Effect of Ni incorporation in cobalt oxide lattice on carbon formation during ethanol decomposition reaction
(
Elsevier B.V.
, 2019 , Article)
In this work, we report the results of catalytic decomposition of ethanol over a porous mixed metal oxide of Ni-Co (NiCoO2) and analyze the effect of Ni incorporation in Co3O4 lattice on the activity and hydrogen selectivity ...
Experimental analysis of additively manufactured thin-walled heat-treated circular tubes with slits using AlSi10Mg alloy by quasi-static axial crushing test
(
Elsevier Ltd
, 2019 , Article)
In this study, additively manufactured aluminum thin-walled tubes with different slit dimensions are proposed to improve energy absorption efficiency. A total of 18 samples, which varied in the number of slits, slit length, ...
Nitric oxide releasing chitosan-poly (vinyl alcohol) hydrogel promotes angiogenesis in chick embryo model
(
Elsevier B.V.
, 2019 , Article)
The lack of angiogenic activity is one of the serious complications of chronic wounds associated with delayed wound closure, chronic ulceration, and subsequent limb amputation. Multiple lines of evidence suggest that nitric ...
Effect of rock mineralogy on Hot-CO2 injection for enhanced gas recovery
(
Elsevier B.V.
, 2019 , Article)
Conventional gas reservoirs are one of the viable options for CO2 enhanced gas recovery and sequestration. Injection of hot CO2 into depleted reservoirs is expected to improve gas recovery. Static adsorption and core ...

Elsevier Ltd
, 2019 , Article)
This work presents a number of integrated strategies aimed at enhancing the performance of the diesel engine and the subsequent reduction of its associated emissions. Three novel spiral-helical shaped intake manifolds with ...
Using the theory of planned behavior to predict the use of an upcoming public transportation service in Qatar
(
Elsevier Ltd
, 2019 , Article)
Public transportation systems play a major role in accommodating public travel needs. To accommodate the need for public transportation in Qatar, a metro network is currently under construction. However, commuters have ...
Effects of time-lagged meteorological variables on attributable risk of leishmaniasis in central region of Afghanistan
(
Elsevier B.V.
, 2019 , Article)
Background
Leishmaniasis remains one of the world's most neglected vector-borne diseases, affecting predominantly poor communities mainly in developing countries. Previous studies have shown that the distribution and ...
