Improved bi-functional oxygen electrocatalytic performance of PteIr alloy nanoparticles embedded on MWCNT with Pt-enriched surfaces
(Energy, 2020)Multi-walled carbon nanotube supported PteIr nanoparticles (PteIr/MWCNT) with different elemental ratios were synthesized by one-pot co-reduction approach under ambient conditions. The PteIr catalysts exhibit improved ... -
In Silico and In Vitro Screening of 50 Curcumin Compounds as EGFR and NF-κB Inhibitors
(MDPI, 2022)The improvement of cancer chemotherapy remains a major challenge, and thus new drugs are urgently required to develop new treatment regimes. Curcumin, a polyphenolic antioxidant derived from the rhizome of turmeric ... -
In vitro corrosion of titanium nitride and oxynitride-based biocompatible coatings deposited on stainless steel
(MPDI, 2020)The reactive cathodic arc deposition technique was used to produce Ti nitride and oxynitride coatings on 304 stainless steel substrates (SS). Both mono (SS/TiN, SS/TiNO) and bilayer coatings (SS/TiN/TiNO and SS/TiNO/TiN) ... -
In-situ ultrasonic monitoring of zeolite A crystallization from coal fly ash
(Elsevier, 2012)In this study, high phase purity of zeolite A was prepared from coal fly ash precursors. The molar regime of both the clear solution extract and unseparated fly ash slurry was adjusted to achieve the right composition for ... -
Influence of quantum dot surface on electrochemical DNA sensing mechanism
(Wiley, 2020)Owing to their high surface‐to‐volume ratio, electrocatalytic activity, biocompatibility and novel electron transport properties, quantum dots (QDs) are highly attractive materials for the ultrasensitive detection of ... -
