Activity-induced Near-infrared Spectral Variability at 29P/Schwassmann–Wachmann 1, 2017–2022
The Planetary Science Journal29P/Schwassmann–Wachmann 1 (SW1) is both the first-discovered active Centaur and the most outburst-prone comet known. The nature of SW1’s many outbursts, which regularly brighten the comet by 5 mag or more, and what processes power them has been of ...

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite
Advanced Functional Materials, EarlyView.The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Scientific Reports, 2018 We previously reported that ice slurry ingestion reduced forehead skin temperature, thereby potentially reducing brain temperature (Tbrain). Therefore, in the current study, we investigated the effect of ice slurry ingestion on Tbrain using proton ...

Probing molecular motion by double-quantum (13C,13C) solid-state NMR spectroscopy: Application to ubiquitin [PDF]
, 2010 We demonstrate the use of two-dimensional (13C,13C) double-quantum spectroscopy to detect molecular dynamics by solid-state NMR. Data collected on tyrosine-ethylester (TEE) are in line with previously determined (1H,13C) order parameters.

Advanced Functional Materials, EarlyView.A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)

Reconstructing ice-sheet accumulation rates at ridge B, East Antarctica [PDF]
, 2004 Understanding how ice sheets responded to past climate change is fundamental to forecasting how they will respond in the future. Numerical models calculating the evolution of ice sheets depend upon accumulation data, which are principally available from ...

The Martian mid-latitude subsurface ice is the remnant of a past ice sheet
Communications Earth & EnvironmentOn Mars, a relatively pure water ice layer lies beneath several centimeters of dry-soil at midlatitudes. Its widespread presence poleward of 60° latitude was detected by remote neutron spectroscopy.
