Thirty years of high-voltage injuries: comparative analysis of train surfing and work-related cases with a focus on trauma-associated diagnoses.

Introduction: High-voltage electrical injuries from train surfing pose a unique challenge, often involving severe burns and multisystem trauma. This study retrospectively analyzed train surfing injuries over 30 years, with a focus on trauma-associated diagnoses and comparing them to work-related high-voltage injuries.

Methods: A retrospective review of 87 high-voltage injury cases was conducted, including 30 train surfing and 57 work-related cases.

High Voltage and Train-Surfing Injuries: A 30-Year Retrospective Analysis of High-Voltage Trauma and Its Impact on Cardiac Biomarkers.

: High-voltage electrical injuries (HVEIs) represent a complex and life-threatening entity, frequently involving multi-organ damage. While traditionally linked to occupational hazards, train surfing-riding on moving trains-and train climbing-scaling stationary carriages-have emerged as increasingly common causes among adolescents. Popularized via social media, these behaviors expose individuals to the invisible danger of electric arcs from 15,000-volt railway lines, often resulting in extensive burns, cardiac complications, and severe trauma.

Deciphering Size and Shape Effects on the Structure Sensitivity of the CO Methanation Reaction on Nickel.

This study advances the understanding of structure sensitivity in CO methanation over nickel-based catalysts by highlighting the combined influence of the metal nanoparticle (NP) size and shape on catalytic performance. Density functional theory (DFT) calculations of the metal nanoparticle structure and activity provide the theoretical underpinnings of the experimentally observed structure sensitivity of CO methanation over nickel-based catalysts. This is achieved by taking into account the diversity of shapes of metal nanoparticles (NPs) under the reaction conditions and the corresponding distribution of active sites at different metal NP sizes.

High-Voltage Injuries and Train Surfing: A 30-Year Review of Epidemiology, Treatment, and Outcomes.

High-voltage injuries associated with train surfing are a distinct subset of electrical injuries, yet detailed analyses remain limited. This study retrospectively reviewed train-surfing injuries admitted between 1994 and 2024, comparing their characteristics and outcomes to work-related high-voltage injuries. Medical records of 102 patients admitted for high-voltage injuries were analyzed, including 32 train-surfing and 70 work-related cases.

Impact of Tungsten Loading on the Activation of Zeolite-Based Catalysts for Methane Dehydroaromatization.

To improve the performance of zeolite-based catalysts for the methane dehydroaromatization (MDA) reaction, it is of importance to understand the nature of the catalytically active phase. Although many studies have been devoted to unraveling the structure of the active site, there is still no consensus. Monomeric, dimeric, and/or clusters of molybdenum oxide or tungsten oxide are proposed precatalyst structures.
