Impact Induced Oxidation and Its Implications for Early Mars Climate

Geophysical Research Letters, 2023
H2 in a CO2 atmosphere may serve as a potential solution to the early Mars climate paradox, but its unknown sources cast doubts on the proposed mechanism. Impact cratering is an energetic process that may modify the surface redox budget.

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

V-type Asteroids as the Origin of Mesosiderites

The Planetary Science Journal, 2023
We present the results of a campaign of hypervelocity impact experiments on natural mesosiderite targets, using representative main asteroid belt impact speeds. The objective is to document further the surface evolution of iron-rich asteroids.

Enhancing Stability of Few‐Layer Black Phosphorus (FLBP) Through Nitrocellulose Coating: A Robust Defense Mechanism Against Degradation

Advanced Materials Interfaces, EarlyView.
In this research, a simple and scalable strategy for protection of a few‐layer black phosphorus (FLBP) with a cellulose nitrate‐based material is presented. The FLBP is structurally and morphologically characterized. The FLBP stability with and without nitrocellulose protection is monitored by interferometric method, surface profile examination, and ...

Molecular Inks for the Development of Complex 3D In‐Mold Electronics

Advanced Materials Technologies, EarlyView.
Molecular inks (MINKs) enable the fabrication of thermoformed 3D circuits by decoupling the forming and metallization steps. Following thermoforming, intense pulsed‑light or thermal processing converts the patterned MINKs into complex 3D conductive tracks with improved stretchability and electrical performance, advancing low‑cost, high‑performance in ...

Landslides on Ceres: Diversity and Geologic Context. [PDF]

, 2019
Landslides are among the most widespread geologic features on Ceres. Using data from Dawn's Framing Camera, landslides were previously classified based upon geomorphologic characteristics into one of three archetypal categories, Type 1(T1), Type 2 (T2 ...

Understanding Ionic Flow in Nanofluidic Blind‐Hole Anodic Aluminum Oxide (AAO) Membranes for Osmotic Energy Generation

Advanced Materials Technologies, EarlyView.
Anodic aluminum oxide (AAO) membranes have traditionally served as structural supports in osmotic energy systems. Here, blind‐hole AAO membranes are demonstrated as active ion‐selective platforms with tunable nanopore structures. By balancing membrane resistance, ion selectivity, and flux, enhanced performance is achieved, delivering a maximum power ...
