Enhanced photocatalytic performance of WON@porous TiO2 nanofibers towards sunlight-assisted degradation of organic contaminants
(
Royal Society of Chemistry
, 2018 , Article)
In the last few decades, TiO2 has been widely used in different types of photocatalytic applications. However, the relatively large optical band gap (∼3.2 eV), low charge carrier mobility and consequently its low quantum ...
Current injection 1.54 µm light-emitting devices based on Er-doped GaN/AlGaN multiple quantum wells
(
OSA - The Optical Society
, 2016 , Article)
We report on the growth, fabrication and electroluminescence (EL) characteristics of light-emitting diodes (LEDs) based on Er-doped GaN (GaN:Er) and GaN/AlGaN multiple quantum well (MQW:Er) active layers. The LED structures ...

(
Wiley
, 2018 , Article)
Cystic fibrosis (CF) is an autosomal recessive genetic disease caused by mutations in the CFTR gene, with various clinical manifestations that affect pulmonary, digestive, exocrine and male reproductive functions as well ...
Corrosion of general oil-field grade steel in CO2 environment - An update in the light of current understanding
(
Electrochemical Science Group
, 2017 , Article)
In this review, we discussed the current mechanistic understanding and effects of key parameters on corrosion of carbon and low alloy steel (CLAS) in CO2 environments. In particular, we emphasized on the current understanding ...
Secretory laccase from pestalotiopsis species CDBT-F-G1 fungal strain isolated from high altitude: Optimization of its production and characterization
(
MDPI AG
, 2019 , Article)
Microorganisms producing laccases may be used for the pretreatment of lignocellulosic biomass to recover fermentable sugar. Very few fungi and other microbes growing in high altitudes have been tested for this purpose. As ...
Kinetics of alkoxysilanes hydrolysis: An empirical approach
(
Nature Research
, 2019 , Article)
Alkoxysilanes and organoalkoxysilanes are primary materials in several industries, e.g. coating, anti-corrosion treatment, fabrication of stationary phase for chromatography, and coupling agents. The hydrolytic polycondensation ...
Do older adults with multimorbidity meet the recommended levels of physical activity? An analysis of Scottish health survey
(
MDPI AG
, 2019 , Article)
There is a positive association between physical activity (PA) and improved health in older adults. The objective of this study was to assess the prevalence and determinants of meeting recommended levels of PA among older ...
