Dynamic spin injection into chemical vapor deposited graphene
Applied Physics Letters, 2012 We demonstrate dynamic spin injection into chemical vapor deposition (CVD) grown graphene by spin pumping from permalloy (Py) layers. Ferromagnetic resonance measurements at room temperature reveal a strong enhancement of the Gilbert damping at the Py/graphene interface, indeed exceeding that observed in Py/platinum interfaces. Similar results are also

Performance Comparison of the Vapor-Injection Cycle in Terms of Branching Points of the Injection Stream [PDF]
, 2012 The performance of the two types of vapor-injection (VI) cycles in a heat pump system is compared. The vapor-injection cycle using an internal heat exchanger (IHX) has a choice to select the branching point of the injection stream.

A case study on the impact of severe convective storms on the water vapor mixing ratio in the lower mid-latitude stratosphere observed in 2019 over Europe [PDF]
Atmospheric Chemistry and Physics, 2022 Extreme convective events in the troposphere not only have immediate impacts on the surface, but they can also influence the dynamics and composition of the lower stratosphere (LS). One major impact is the moistening of the LS by overshooting convection.

Adsorption and Desorption of Decane Using Non-Carbon Adsorbents
Asian Journal of Atmospheric Environment, 2021 A high concentration of volatile organic compounds (VOCs) is emitted during dry cleaning processes. Although carbonaceous materials have been widely tested for the control of VOC emission, there is a risk of fire when a large amount of VOCs is ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.
