New Climatology of Martian Water Vapor Column Abundance Derived From NOMAD LNO Nadir Observations Over Martian Years 34–38

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract We present a new climatology of Martian water vapor column abundance derived from nadir dayside observations made by the Nadir and Occultation for MArs Discovery (NOMAD) instrument suite as part of the ExoMars Trace Gas Orbiter (TGO) mission. H2O vertical column densities are retrieved by applying an Optimal Estimation inversion scheme to the ...

PRAXIS: a low background NIR spectrograph for fibre Bragg grating OH suppression

open access: yes, 2012
Fibre Bragg grating (FBG) OH suppression is capable of greatly reducing the bright sky background seen by near infrared spectrographs. By filtering out the airglow emission lines at high resolution before the light enters the spectrograph this technique ...

Strong magnetic field effect on above-barrier transport in Pb-p-HgCdTe Schottky barriers [PDF]

open access: yes, 2012
Due to large difference in effective masses of light and heavy holes it is usually supposed that the above-barrier current in Schottky barriers on p-type semiconductor is controlled only by the heavy holes.

Restricting Copper Reconstruction with Ultrathin Polydopamine for Selective and Stable Electrochemical CO2 Reduction Reaction to C2 Products

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
An ultrathin polydopamine coating on copper microcubes mitigates the surface reconstruction during EC‐CO2RR. Copper nanocubes form on the surface of the microcubes in the early stages of the EC‐CO2RR, contributing to suppressed surface reconstruction and sustained Faradaic efficiency for C2 products.

Facet‐Tailored Co3O4 as Electronic Regulator and Stabilizing Support for Ru Nanocluster: Toward Efficient Alkaline HER

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 2, March 2026.
Facet‐engineered Ru@Co3O4 nanosheets precisely anchor Ru nanoclusters on the Co3O4 (111) facets, optimizing the hydrogen‐bond network of interfacial water and downshifting the Ru d‐band center. The Ru@Co3O4 NSs show outstanding HER activity and long‐term durability in AEMWE devices. This work demonstrates a crystal facet engineering strategy to develop
