Ag‐Induced Phase and Defect Engineering of Co‐Evaporated Sb2Se3 Thin Films for Enhanced Photovoltaic Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The sequential formation of Ag2Se and AgSbSe2 phases at the Sb2Se3/Mo interface upon Ag incorporation in co‐evaporated Sb2Se3 solar cells promotes grain growth and defect passivation. These newly formed intermediate phases enhance crystallinity and suppress recombination, leading to significant improvements in open‐circuit voltage, fill factor, and ...

Analytic Study of Transverse Shunt Resistance and Even-Odd Mode Coupling of a Rod Type RFQ

open access: yes, 2007
To minimize the ohmic power losses, it is necessary to maximize the transverse shunt resistance, R shunt . The cell of a rod-type RFQ is modelled by a parallel two-rod transmission line supported above a parallel ground conductor by two legs.

Shunt properties of large intrathoracic airways

open access: yes, 1994
The impedance of the wall of human intrathoracic trachea and central airways was measured by submitting preparations of excised airways to forced oscillations at various frequencies from 2 to 32 Hz. Both real (resistance) and imaginary (reactance) parts

Triboelectric–Electromagnetic Generator‐Enabled Hybrid Power Backpack for Self‐Powered Field Safety Management

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A lightweight hybrid backpack integrating SC‐TENGs and R‐EMGs harvests biomechanical energy during walking. With a low activation speed of 3 km h−1 and a high specific power of 0.18 W kg−1, it enables self‐powered field safety management. The power backpack refers to an energy‐harvesting solution engineered to mitigate battery reliance in wearable ...

The Role of GABA Shunt and Hepatic GABA Transporters on Hyperinsulinemia and Insulin Resistance

open access: yes, 2021
Hepatic lipid accumulation, a hallmark of type 2 diabetes (T2D), increases hepatic gamma-aminobutyric acid (GABA) production through the GABA shunt and release by electrogenic GABA transporters.
