The Role of Key Impurity Elements on the Performance of Aluminium Electrolysis -Current Efficiency and Metal Quality
(
wiley
, 2016 , Book chapter)
The behaviour of phosphorus and silicon in industrial aluminium cells was measured in QATALUM cells by analysis of bath and metal after addition of AlPO4, Na3PO4 and SiO2 to the bath. Phosphorus showed a much longer retention ...
Trap States and Their Dynamics in Organometal Halide Perovskite Nanoparticles and Bulk Crystals
(
American Chemical Society
, 2016 , Article)
Organometal halide perovskites have attracted tremendous attention for optoelectronic applications. Charge carrier trapping is one of the dominant processes often deteriorating the performance of devices. Here, we investigate ...
Sensitive detection and glycoprofiling of a prostate specific antigen using impedimetric assays
(
Royal Society of Chemistry
, 2016 , Article)
This study presents a proof-of-concept for the development of an impedimetric biosensor for ultra-sensitive glycoprofiling of prostate specific antigen (PSA). The biosensor exhibits three unique characteristics: (1) analysis ...

Three amidosulfobetaine surfactants were synthesized namely: 3‐(N‐pentadecanamidopropyl‐N,N‐dimethyl ammonium) propanesulfonate (2a); 3‐(N‐heptadecanamidopropyl‐N,N‐dimethyl ammonium) propanesulfonate (2b), and ...
Effect of extraction solvents on polyphenols and antioxidant activity of medicinal halophytes
(
Pakistan Botanical Society
, 2016 , Article)
This study was conducted to determine the most effective solvent for extraction of polyphenols and antioxidant activity of medicinally important coastal halophytes (Thespesia populneoides, Salvadora persica, Ipomoea ...
Investigation of the hydrogen adsorbed density inside the pores of MOF-5 from path integral grand canonical Monte Carlo at supercritical and subcritical temperature
(
Science in China Press
, 2016 , Article)
We examine the high density limit of the adsorption isotherms of hydrogen on MOF-5. The isotherms are calculated using quantum GCMC simulations over the pressure range: 0–150 atm (1 atm = 1.01325 × 105 Pa) in the subcritical ...
