Toxicological approach to setting spacecraft maximum allowable concentrations for carbon monoxide [PDF]

open access: yes
The Spacecraft Maximum Allowable Concentrations (SMACs) are exposure limits for airborne chemicals used by NASA in spacecraft. The aim of these SMACs is to protect the spacecrew against adverse health effects and performance decrements that would ...

Development Status and Future Prospects of Hydrogen Energy Technology: Production, Storage, and Cost Analysis

open access: yesAdvanced Energy and Sustainability Research, Volume 6, Issue 10, October 2025.
Hydrogen is an energy carrier, produced from renewable and nonrenewable resources. It can be stored in a variety of materials and transported to distant locations. This article reviews progress in hydrogen technology by looking at environmental and economic impact, cost analysis, and policy support at government level as way forward for bringing it to ...

Cardiac Arrest After Inhalation of Hazardous Gas Suspected Hydrogen Sulfide at Cucumber Pickle Factory: Two Case Reports

open access: yesClinical Case Reports, Volume 13, Issue 10, October 2025.
ABSTRACT We report two cases of acute occupational exposure to hazardous gas, suspected to be hydrogen sulfide. The 34‐year‐old male and 48‐year‐old female patients worked as cleaners at a pickled cucumber factory. The two victims cleaned a waste tank (containing organic waste that can produce hydrogen sulfide) that had been abandoned for 2 years, with

The Potential of Cations for Carbon Dioxide Electroreduction

open access: yesChemCatChem, Volume 17, Issue 20, October 20, 2025.
Depending on the catalyst, cations play a crucial role in enabling CO2${\rm CO}_2$ activation and conversion to multicarbon products or promoting water reduction. These effects can be predicted in terms of cation‐induced electrostatic potential. Cations also affect surface dissolution by promoting precursors, stabilizing dissolved complexes, or ...

A Proof‐of‐Concept Membrane Module Concept for Solar Thermal Water Splitting Using Oxygen Transport Membranes

open access: yesEnergy Technology, Volume 13, Issue 10, October 2025.
Solar thermal water splitting with oxygen transport membranes offers a sustainable path to hydrogen production and enhances efficiency by potentially lowering the required temperature below 1000 °C. This study presents a scalable proof‐of‐concept module with an optimized solar heat integration.
