High-temperature He+ Irradiation of Low-iron-bearing Olivine: Laboratory Simulations of Space Weathering on Mercury

The Planetary Science Journal
The surface of Mercury is highly space weathered, and the products of space weathering are different than on the Moon. Here we simulate the interaction of solar wind ions with the surface of Mercury by implanting low-iron-bearing (∼3 wt% Fe) olivine ...

Degradation of Solar Array Components in a Combined UV/VUV High Temperature Test Environment

E3S Web of Conferences, 2017
BepiColombo is the joint mission of the European Space Agency (ESA) and the Japanese Aerospace Exploration Agency (JAXA) to explore the planet mercury. The European contributions, namely the mercury transfer module (MTM) and the mercury planetary orbiter

Molecular Bottom‐Up Design of Single‐Site Copper‐Palladium Catalysts for Selective Glycerol Electro‐Oxidation

Advanced Energy Materials, EarlyView.
A bimetallic Cu‐Pd single‐site catalyst for the selective and efficient electrooxidation of glycerol to formate and C3‐products (lactate, glycolate, glycerate) is reported. Experimental and theoretical studies shed light on the catalyst function and reveal that Pd sites facilitate the adsorption of hydroxyl (C‐OH) species which prevents C‐C bond ...

Understanding the Effects of Micrometeoroid Bombardment on Graphite-rich Mercury Analogs through Laboratory Experiments and Electron Microscopy Analysis

The Planetary Science Journal
Space weathering alters the spectral, microstructural, and chemical characteristics of the surface of Mercury, and an effective way to understand it is in the laboratory.

Consolidating and Crushing Exoplanets: Did it happen here?

, 2015
The Kepler mission results indicate that systems of tightly-packed inner planets (STIPs) are present around of order 5% of FGK field stars (whose median age is ~5 Gyr).

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

Advanced Energy and Sustainability Research, EarlyView.
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.

Learning to explain environmental crises: A dialogic analysis of teacher professional learning between Chile and the United States

British Educational Research Journal, EarlyView.
Abstract Many studies and initiatives are animated by the potential for science education to intervene in the climate crisis and crises of environmental degradation and disinformation. For science teachers to learn to address these issues in their classes, their teaching must expand beyond scientific facts and face controversial social aspects. Dealing
