AI Article Synopsis

  • The study examined how temperature affects the sputtering process of coronene, an organic molecule, when exposed to Au and C ions at temperatures of 100 K and 300 K.
  • Researchers used strong field photoionization to analyze the sputtered neutral flux, focusing on how the flight time and kinetic energy distributions of both intact and fragmented molecules changed.
  • The findings help to understand the impact of temperature on the behavior and composition of sputtered materials in ion beam experiments.

Article Abstract

Temperature effects in the sputtering of an organic molecule were investigated by subjecting a well defined film of coronene to Au and C primary ions at 100 and 300 K. Strong field photoionization of the sputtered neutral flux was employed to monitor the change in flight time and kinetic energy distributions of intact and fragmented species.

The West Antarctic Peninsula (WAP) is a hotspot of climate warming, evidencing glacier retreat and a decrease in the fast-ice duration. This study provides a > 30-y time-series (1987-2022) on annual and seasonal air temperatures in Potter Cove (Isla 25 de Mayo/King George Island). It investigates the interaction between warming, glacial melt, fast-ice and the underwater conditions (light, salinity, temperature, turbidity) over a period of 10 years along the fjord axis (2010-2019), and for the first time provides a unique continuous underwater irradiance time series over 5 years (2014-2018).

is known for its potential antioxidant and anti-inflammatory properties, attributed to triterpenes, flavonoids, and tannins. This study aimed to optimise the extraction process for aerial parts of using vortex extraction. A Box-Behnken experimental design coupled with response surface methodology was employed to evaluate the effects of three independent variables: sample-to-solvent ratio, velocity, and temperature.

Leaf dry matter content (LDMC) is an important determinant of plant flammability. Investigating global patterns of LDMC could provide insights into worldwide plant flammability patterns, informing wildfire management. We characterised global patterns of LDMC across 4074 species from 216 families, revealing that phylogenetic and environmental constraints influence LDMC.

A Novel cold-active chitin deacetylase from Shewanella psychrophila WP2 (SpsCDA) was overexpressed in Escherichia coli BL21 and employed for deacetylation of chitin to chitosan. The produced chitosan was characterized, and its antifungal activity was investigated against Fusarium oxysporum. The purified recombinant SpsCDA appeared as a single band on SDS-PAGE at approximately 60 kDa, and its specific activity was 92 U/mg.
