An experimental system based on Laser Induced Breakdown Spectroscopy (LIBS) has been used to analyze various ferrous samples. A fibre optic system has been used to transmit the incident laser pulse which produces the plasma plume at the surface of the analyte and to transmit back to a spectrometer the optical radiation emitted by the plasma. The measuring system may therefore be placed remote from the analyte which may be situated in a hostile environment such as an operating nuclear reactor. Results show that the system is capable of detecting chromium, nickel, manganese, molybdenum, silicon and vanadium at concentrations smaller than 5x10(-4) g/g

Remote Activation Catalysis: Interparticle Hydrogen Spillover-Assisted Cumene Synthesis from Propane and Benzene.
Small
January 2025
Department of Chemistry and Life Science, Yokohama National University, Yokohama, 240-8501, Japan.
Hydrogen spillover, particularly when involving "interparticle" hydrogen spillover, offers a unique opportunity to enhance catalytic efficiency by remote activation of surface acidity. Building on this concept, this study aims to investigate physically mixed alumina-supported platinum nanoparticles (Pt/AlO) and zirconia-supported tungsten oxide (WO/ZrO) in promoting the direct synthesis of cumene from benzene and propane at 300 °C. The reaction with Pt/AlO alone afforded propylene as the only product, indicating the successive reaction route of Pt-catalyzed dehydrogenation of propane, followed by acid-catalyzed alkylation.

Purpose: To report a case of herpes simplex virus (HSV) endotheliitis inducing acute interface fluid syndrome in a patient with a remote history of laser in situ keratomileusis (LASIK).
Methods: Case report and literature review.
Results: A 51-year-old man with a history of LASIK 16 years prior presented with unilateral HSV endotheliitis and was found to have acute interface fluid syndrome secondary to endothelial decompensation.
A review of uranium (U) elemental detection methods.

National Key Laboratory of Uranium Resources Exploration-Mining and Nuclear Remote Sensing, Beijing, 100029, China.
With the increasing demand for energy, nuclear energy has been developing rapidly. The quantitative detection and qualitative identification of uranium (U) are of great significance for the comprehensive and efficient use of U resources and the control of nuclear and radioactive substances. In this study, the detection of U is divided into liquid sample detection, solid sample detection, gas sample detection, and industrial detection from the perspectives of the sample state and detection environment.

Department of Environmental Science, Zhejiang University, Hangzhou 310058, PR China. Electronic address:
Zero-valent iron (ZVI) has demonstrated high potential for in-situ remediation of contaminated groundwater and soils. Upon exposure to oxygen, ZVI generates reactive oxygen species (ROS). In parallel with the electron transfer mediated-reductive path, ROS plays a critical role in the oxidative degradation of organic pollutants during ZVI remediation of groundwater and soil.

Department of Engineering Science and Mechanics, The Pennsylvania State University, University Park, Pennsylvania, 16802, USA.
Despite rapid developments of wearable self-powered sensors, it is still elusive to decouple the simultaneously applied multiple input signals. Herein, we report the design and demonstration of stretchable thermoelectric porous graphene foam-based materials via facile laser scribing for self-powered decoupled strain and temperature sensing. The resulting sensor can accurately detect temperature with a resolution of 0.
