Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Enhancing IR‐MALDESI MSI Spatial Resolution Through Beam Constriction With a Ring‐Actuated Iris

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 16, 30 August 2026.
ABSTRACT Rationale Infrared matrix‐assisted laser desorption electrospray ionization (IR‐MALDESI) mass spectrometry imaging (MSI) enables label‐free, spatially resolved molecular analysis of biological tissues under ambient conditions. While improving spatial resolution is important for mapping fine tissue structures, mid‐infrared (IR) lasers are ...

Toward a Greener Production of Materials: Water‐Minimized Synthesis of NiAl‐, NiFe‐, and CoAl‐Layered Double Hydroxides for Photocatalytic CO2 Reduction

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.
This study provides a water‐minimized strategy to synthesize layered double hydroxides using resonant acoustic mixing. The catalysts’ CO2 reduction performance strongly depends on their physicochemical properties, which can be controlled during the synthesis.

NiO Dissolution in Molten Carbonate Fuel Cell Cathodes: Challenges and Strategies for Long‐Term Stability

open access: yesChemElectroChem, Volume 13, Issue 13, 2 July 2026.
Molten carbonate fuel cells (MCFCs) enable efficient power generation and CO2 capture but suffer from nickel oxide (NiO) cathode dissolution, which limits lifetime. This review summarizes strategies to mitigate NiO degradation, including coatings, doping, alternative cathode materials, and electrolyte modification.

Chemically Self‐Powered Pre‐Activation Strategy for Catalytic Purification of Lithium‐Ion Battery Thermal Runaway Off‐Gas

open access: yesBattery Energy, Volume 5, Issue 4, July 2026.
The catalytic oxidation method is employed to purify lithium battery thermal runaway fumes. Superoxide (e.g., KO2) provide heat to activate the catalyst, while a blower supplies oxygen and regulates temperature, achieving a safe and efficient purification process with hydrogen and carbon monoxide removal rates exceeding 87%. ABSTRACT During lithium‐ion
