Model Calculations for Cosmogenic Nuclides in Meteorites and the Lunar Surface. 1. Long‐lived Radionuclides

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Production rates for the cosmogenic radionuclides 10Be, 14C, 26Al, 36Cl, 41Ca, 53Mn, and 60Fe in a large variety of meteorites, that is, ordinary chondrites (H, L, LL), carbonaceous chondrites, HED meteorites, ureilites, Martian meteorites, and iron meteorites and in the uppermost ~2 m of the lunar surface are modeled.

Terrestrial ages of meteorites from the Atacama Desert (Chile) and insights into the past meteorite flux to Earth

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The Atacama Desert in Chile is characterized by its high meteorite density and old meteorite terrestrial ages. In this work, we present new terrestrial ages derived from measurements of the concentration of cosmogenic 36Cl in the metal fraction of 51 ordinary chondrites collected over a 6.8 km2 area located in the Catalina Dense Collection ...

A new gas–solid reaction model for voloxidation process with spallation

open access: yesNuclear Engineering and Technology, 2018
A new methodology, the crack–spallation model, has been developed to analyze gas–solid reactions dominated by crack growth inside of the solid reactant and spallation phenomena. The new model physically represents three processes of the reaction progress:

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 ...

A Review on Cracking in Laser Additive Manufacturing of Nickel‐Based Superalloys: Types, Formation Mechanisms, and Suppression Strategies

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...

Amorphous Hydrogenated Silicon Carbide Interlayers: Chemical, Optical, and Tribological Behavior for Improving Adhesion of Carbon‐Based Films to Ferrous Alloy

open access: yesSurface and Interface Analysis, Volume 58, Issue 4, Page 246-261, April 2026.
ABSTRACT Diamond‐like carbon thin films have been gaining attention in the last years due to their unique properties, such as low friction coefficient and high wear resistance. However, the lack of adhesion between DLC coatings and ferrous alloys complicates their wider industrial application.

Analysis of the coal seam spalling-failure mechanism based on the seepage instability theory.

open access: yesPLoS ONE, 2019
Coal and gas outburst is a common coal-rock dynamic disaster. Such accidents frequently occur, and the mechanism underlying the occurrence of these outbursts is complex.
