Dielectric and Gate Metal Engineering for Threshold Voltage Modulation in Enhancement Mode Monolayer MoS2 Field Effect Transistors

Advanced Materials, EarlyView.
Enhancement‐mode monolayer MoS2 FETs with low threshold voltage are essential for low‐power electronics. The threshold voltage can be tuned by the gate metal work function when the semiconductor/dielectric interface is clean. Interfaces between monolayer MoS2 and ZrO2 or hBN allow effective work‐function modulation of the threshold voltage, in contrast

Low-energy and accelerated hydrogen release from MgH2–5 wt% NaTiOxH catalyzed hydrogen storage reactor by graphite responsive microwave

Journal of Magnesium and Alloys
Owing to high thermal stability and large reaction enthalpy, MgH2 has high reaction temperatures and sluggish reaction kinetics in the dehydrogenation process, which consumes lots of energy.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Effect of various processing parameters on the quality of papaya fruit tea [PDF]

, 2005
Exotic fruits from which drinks are ma de in most tropical countries are so abundant and such in a great variety, that it would probably be impossible for people to sample all of them, but they worth a try.

Counterion‐Controlled Photocatalytic Doping of Organic Semiconductors

Advanced Materials, EarlyView.
Counterion size is shown to actively control photocatalytic doping in organic semiconductors. Small anions suppress aggregation of acridinium photocatalysts, enhance electron transfer, and dramatically increase doping efficiency. This simple strategy enables conductivities up to 2000 S cm−1 in benchmark polymers, revealing counterions as a powerful yet
