The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

Journal of Field Robotics, Volume 43, Issue 6, Page 4094-4115, September 2026.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

Direct Detection of Hydrogen Reveals a New Macroscopic Crustal Water Reservoir on Early Mars

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The next great leap in Martian exploration is the return of samples to Earth. Maximizing their scientific value requires non‐destructive analytical techniques for early three‐dimensional characterization. Neutron computed tomography (CT), highly sensitive to hydrogen, complements conventional X‐ray CT and enables the detection of hydrous ...

Decoupling Electronic Activation and Pore Connectivity in Acidic Oxygen Reduction on Metal‐Free Biomass‐Derived Carbon Catalysts

ChemElectroChem, Volume 13, Issue 16, 18 August 2026.
Acidic ORR on biomass‐derived carbon is described by partially separable electronic and transport contributions. Defect‐derived electronic states are associated with the onset region, whereas connected three‐dimensional pore pathways are associated with accessibility in the transport‐influenced regime.

Monte carlo assessment of advanced shielding materials for space‐efficient radiotherapy vault design

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Conventional radiotherapy vault shielding typically employs 2 to 3 meters of ordinary concrete, consistent with NCRP Report 151 reference data. While NCRP 151 specifies dose‐based design goals rather than mandating particular materials, the practical default of concrete results in vault footprints of 150 to 200 m2 per linac, which ...

Neutron Reflectometry and Compression of Graded Hydrogel Surfaces

Advanced Materials Interfaces, Volume 13, Issue 15, 4 August 2026.
Highly‐entangled and covalently‐crosslinked hydrogels with thin and thick surface gel layers are compressed in neutron reflectometry experiments. Surface gel layer thickness dictates the extent to which the polymer network at the surface of a hydrogel collapses, while crosslinking chemistry, and therefore elastic modulus, impacts the pressure at which ...
