Experimental and theoretical study of oxygen vacancy induced La-doped mesoporous TiO2 for enhanced thermal stability

AIP Advances, 2023
We report a facile synthesis of mesoporous TiO2 with a large specific surface area and rich oxygen vacancies using La-doped TiO2 through high-temperature annealing. Such integration of a unique mesoporous structure and oxygen vacancies provides effective

Antibiofilm activity of a chionodracine‐derived peptide by NMR‐based metabolomics of cell‐free supernatant of Acinetobacter baumannii clinical strains

FEBS Open Bio, EarlyView.
KHS‐Cnd peptide is able to impair biofilm formation and disaggregate mature biofilms in Acinetobacter baumannii clinical isolates. Differences in extracellular metabolites reflect changes in biofilm metabolism due to KHS‐Cnd treatment. Among the differentially represented extracellular metabolites upon KHS‐Cnd treatment, the significantly altered ...

Defect-induced oxygen adsorption on graphene films

, 2018
Although defects on graphene can degrade electron transport and its ability for use as a protection layer, they can also be helpful to tailor the local properties or activate new sites for particular adsorbates. Here, carbon vacancy defects are formed in
