AI Article Synopsis
- The study investigated how electrons behave in a CO-water system using picosecond electron pulse radiolysis at different gas pressures (1 to 118 bar) and temperatures (25 and 35 °C), along with UV-vis transient spectroscopy.
- A specially designed spectroscopic cell was used to control temperature and pressure, enabling direct measurement of electron scavenging even under supercritical conditions.
- Results indicated that electron reactivity was not consistent with varying CO concentrations, highlighting the complex relationship between CO concentration in water and gas pressure.
Article Abstract
The reactivity of electrons in the CO-water system was evaluated through picosecond electron pulse radiolysis at different gas pressures (ranging from 1 to 118 bar) and temperatures (25 and 35 °C) coupled with UV-vis transient spectroscopy. A custom-made spectroscopic cell was utilized for these experiments, which allowed for regulation of temperature and pressure. The scavenging of electrons was measured directly at gas pressures even in the supercritical state, and the results showed a non-monotonic dependence of electron reactivity with CO concentration, in agreement with the changing molar concentration of CO in water under varying pressure.

Aim: Maternal colonization by Enterobacteriaceae that produce extended-spectrum β-lactamases (ESBL-E) has risen, and the antimicrobial resistance of ESBL-E is significant. We aimed to evaluate the rates of ESBL-E colonization among women with preterm premature rupture of membranes (PPROM) and of maternal-neonatal vertical transmission. We also aimed to compare obstetrical and neonatal complications among ESBL-E positive versus negative maternal colonization in pregnancies complicated by PPROM.

Holocaust survivors may be sensitive to additional traumatic events that can awaken memories of their past. The study examined Holocaust survivors' reactions to the October 7 terrorist attack. Data were collected from 118 Israeli Jewish older adults, who were divided into three groups: Survivors with high (n = 17), and with low PTSD symptom levels (n = 69) and a comparison group (n = 32), matched for background variables.

Background: All living organisms exist in a world affected by many external influences, especially water and light. Photonic nanostructures present in certain insects, have evolved over time in response to diverse environmental conditions, facilitating communication within and between species, camouflage, thermoregulation, hydration, and more. Up to now, only a few insect species have been discovered whose elytron changes its color due to permeation of water (or its vapor) through cuticle.

Fungi (, , and , ) impart wood rot, leading to economic and environmental issues. To overcome this issue, toxic chemicals are commonly employed for wood preservation, impacting the environment and human health. Surface coatings based on antimicrobial chitosan (CS) of high molar mass (145 × 10 Da) were tested as wood preservation agents using an innovative strategy involving ultra-pressurizing CS solutions to deposit organic coatings on wood samples.
