Water-based peeling of thin hydrophobic films

, 2017
Inks of permanent markers and water-proof cosmetics create elastic thin films upon application on a surface. Such adhesive materials are deliberately designed to exhibit water-repellent behavior. Therefore, patterns made up of these inks become resistant

The effect of host structure on the selectivity and mechanism of supramolecular catalysis of Prins cyclizations. [PDF]

, 2015
The effect of host structure on the selectivity and mechanism of intramolecular Prins reactions is evaluated using K12Ga4L6 tetrahedral catalysts. The host structure was varied by modifying the structure of the chelating moieties and the size of the ...

Anti-Inflammatory and Antioxidant Activities of Terpene- and Polyphenol-Rich Premna odorata Leaves on Alcohol-Inflamed Female Wistar Albino Rat Liver

Molecules, 2020
Premna odorata Blanco (Lamiaceae) is an ethnomedicinal plant native to different tropical regions. Although some reports addressed their anti-inflammatory, cytotoxic, and antituberculotic effects, their hepatoprotective potential is yet to be discovered.

Seasonal measurements of total OH reactivity fluxes, total ozone loss rates and missing emissions from Norway spruce in 2011 [Discussion paper] [PDF]

, 2012
Numerous reactive volatile organic compounds (VOCs) are emitted into the atmosphere by vegetation. Most biogenic VOCs are highly reactive towards the atmosphere's most important oxidant, the hydroxyl (OH) radical.

Action of Betulinic Acid in the Inhibition of Efflux Pump NorA in Staphylococcus aureus Strains: In Vitro and In Silico Approaches

Chemistry &Biodiversity, EarlyView.
ABSTRACT Antibiotic resistance poses a serious challenge to public health, particularly in the case of Staphylococcus aureus, a Gram‐positive bacterium that employs multiple resistance mechanisms, including efflux pumps such as NorA, which extrude antimicrobial compounds from the cell and reduce antibiotic efficacy. Therefore, the search for substances

A specific group of genes respond to cold dehydration stress in cut Alstroemeria flowers whereas ambient dehydration stress accelerates developmental senescence expression patterns [PDF]

, 2010
Petal development and senescence entails a normally irreversible process. It starts with petal expansion and pigment production, and ends with nutrient remobilization and ultimately cell death.
