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 ...

Effect of Magnetic Field and Oxygen Pressure on the Decomposition of Sm2Fe17N3 Probed Using 57Fe Mössbauer Spectroscopy

physica status solidi (a), Volume 223, Issue 15, 5 August 2026.
The decomposition of Sm2Fe17N3 was investigated under flowing and static high‐purity oxygen with and without a 5 T magnetic field. The reaction was governed mainly by the oxygen‐driven chemical potential, while the magnetic‐field effect was limited. Under static oxygen, selective decomposition into Sm oxide and α‐Fe without iron oxides was achieved ...

Single‐Atom Iron‐Catalyzed Oxidative Esterification: From Methylarenes to the Upcycling of Polystyrene and Lignin‐Derived Feedstocks

Angewandte Chemie, Volume 138, Issue 31, 27 July 2026.
Heterogeneous iron‐catalyzed environmentally benign and sustainable CH‐oxidative esterification methodology has been developed for the synthesis of esters. This challenging reaction has been achieved by the rational design of specific single atom iron‐based catalyst with Fe‐N4 active centers, which empowered the oxidative esterification of methyl and ...

Synthesis of Ethyl Methyl Carbonate: Past, Present, and Future

Advanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
Ethyl methyl carbonate (EMC) is the simplest asymmetric organic carbonate, with properties between dimethyl (DMC) and diethyl (DEC) carbonate, considered a unique green liquid organic compound for lithium batteries (electrolyte) and gasoline blending (octane enhancer additive), among other uses. In accordance, the chemical production of EMC is expected

Coupled Operando Mössbauer‐Raman Spectroscopic Analysis of Iron Molybdate Catalysts During Oxidative Dehydrogenation

ChemCatChem, Volume 18, Issue 15, 14 August 2026.
We demonstrate the potential of a coupled SMS‐Raman setup for the ODH of EtOH over a Fe2(MoO4)3 + MoO3 catalyst during reductive conditions. Coupling both methods allows to distinguish (sub)surface and bulk properties of the material during catalysis, that can be correlated with activity and selectivity data from mass spectrometry.

Iron‐Substituted Zn‐Al LDH‐Derived Mixed Oxides: Tailoring Structure, Composition and Redox Properties for Efficient CO2‐to‐Olefins Conversion

ChemCatChem, Volume 18, Issue 15, 14 August 2026.
LDH‐derived Zn‐Fe‐Al mixed oxides exhibited 40% CO2 conversion and 10.6% yield of light olefins. The composition and the properties of the mixed oxides strongly influenced the selectivity of products, while ZnFe2O4 and iron carbide structure promoted the conversion and the selectivity of light olefins.
