Engineering Plasmonic Reactors for Co2 Reduction: from Nanoscale Catalysts to Novel Reactors

ChemistryEurope, EarlyView.
This mini review highlights the critical role of reactor design in advancing plasmonic CO2reduction technologies. It emphasizes the need to integrate optimized reactors with LSPR materials to enhance catalytic efficiency, light absorption, and hot‐carrier generation. Overcoming challenges in scalability, stability, and product separation.

Mellitic Acid as a Stable Abiotic Precursor for Liquid‐Liquid Phase Separation: An RNA‐Independent Pathway for Prebiotic Compartmentalization

Chemistry – A European Journal, EarlyView.
Evidence is presented that prebiotically accessible mellitic (benzenehexacarboxylic) acid (MAc) is forming liquid droplets with short poly‐L‐lysine. The capacity of MAc to induce liquid‐liquid phase separation with short oligocations, along with abiotic synthesis routes, makes MAc a viable candidate for an ingredient of early prebiotic membraneless ...

Terrestrial Lithium Exploration Adapted From Raman Diagnosis of Phyllosilicates for Mars

Journal of Raman Spectroscopy, EarlyView.
Analyses using a benchtop Raman instrument at the University of Aberdeen and a prototype instrument for remote deployment on Mars based at the University of Leicester successfully discriminated between four varieties of mica (possibly lithium‐rich rocks).

A new model describing Forbush Decreases at Mars: combining the heliospheric modulation and the atmospheric influence

Earth and Planetary Physics, 2020
Forbush decreases are depressions in the galactic cosmic rays (GCRs) that are caused primarily by modulations of interplanetary coronal mass ejections (ICMEs) but also occasionally by stream/corotating interaction regions (SIRs/CIRs).

The ISSI international study team on the martian PBL – status report and plan [PDF]

, 2008
Dynamical processes in the Martian boundary layer provide the means of communication between surface ice deposits and the free atmosphere, and the means of lifting dust from the surface.

Maximizing Scientific Exploitation of Raman Spectroscopy With A.C.M.E. (Atmospheric Chamber for Measurements in Environment)

Journal of Raman Spectroscopy, EarlyView.
Simulated planetary gas detection using the A.C.M.E. chamber and a novel hollow‐core fiber Raman sensor. Controlled atmospheric mixtures were used to evaluate the sensor’s performance, demonstrating its capability to detect gases such as CO₂, O₂, and N₂. The results support the applicability of the HCF‐based Raman sensor in future planetary exploration

A review of volatiles in the Martian interior [PDF]

, 2016
Multiple observations from missions to Mars have revealed compelling evidence for a volatile-rich Martian crust. A leading theory contends that eruption of basaltic magmas was the ultimate mechanism of transfer of volatiles from the mantle toward the ...
