CI chondrite Oued Chebeika 002 links asteroids Bennu and Ryugu to common parent body
Meteoritics &Planetary Science, EarlyView.Abstract CI chondrites are a compositionally primitive group of meteorites that have undergone extensive aqueous alteration, providing insights into the evolution of primitive planetesimals. Oued Chebeika 002 is the most pristine CI chondrite to date.

In-Pile 4He Source for UCN Production at the ESS
Advances in High Energy Physics, 2014 ESS will be a premier neutron source facility. Unprecedented neutron beam intensities are ensured by spallation reactions of a 5 MW, 2.0 GeV proton beam impinging on a tungsten target equipped with advanced moderators.

Ryugu Reference Project: Recommendations from the Measurement Definition Team
Meteoritics &Planetary Science, EarlyView.Abstract Sample return missions play a significant role in planetary science by providing pristine extraterrestrial materials. JAXA's Hayabusa2 and NASA's OSIRIS‐REx missions have returned samples from the C‐type asteroids Ryugu and Bennu, respectively. The chemical and mineralogical compositions of these samples closely resemble those of CI chondrites,

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

Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.In this study, we produced HfN‐based nanoparticles via femtosecond laser ablation in acetone. The nanoparticles exhibit a red‐shifted plasmonic resonance in the NIR‐I window, colloidal stability after coating with polyethyleneglycol, and excellent biocompatibility. The photothermal and X‐ray sensitization therapeutic effects were demonstrated for tumor

Exceptional thermal shock resistance of RSZ/YSZ coatings for rocket engines at 1800 °C
Journal of Advanced CeramicsTo meet the demands for high thrust-to-weight ratios and reusability, rocket engines require thermal barrier coatings (TBCs) capable of withstand 1800 °C for prolonged durations. This study presents a novel quaternary rare earth-stabilized cubic zirconia

Spallation behaviour of a Zr-bulk metallic glass
EPJ Web of Conferences, 2012 Plate impact experiments have been conducted on a Zr-based bulk metal glass (BMG) using a single stage light gas gun. To understand the spallation process of the material, samples were subjected to dynamic tensile loadings of the same amplitude but ...

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1742-1755, May 2026.ABSTRACT In the present study, creep tests of a TiAl alloy were conducted using miniature specimens (d = 2 mm) under various conditions to investigate their creep properties at 760°C. The test results indicate that creep rupture time obtained using miniature specimens at identical applied stress levels increase with the order of test condition Ar gas ...
