In‐Wheel Piezoelectric DC Power Generator With Zero Resistive Torque
Advanced Science, EarlyView.In this paper, we present a wheel‐shaped direct‐current piezoelectric generator (DC‐PG) that fundamentally overcomes these constraints by producing phase‐stable DC electricity directly from rolling motion. By embedding this system into suitcase wheels, we demonstrated a fully integrated real‐time location tracking system powered solely by mechanical ...

Surface oxide on thin films of yttrium hydride studied by neutron reflectometry [PDF]
, 2012 The applicability of standard methods for compositional analysis is limited for H-containing films. Neutron reflectometry is a powerful, non-destructive method that is especially suitable for these systems due to the large negative scattering length of H.

Enhancement in Curie Temperature of Yttrium Iron Garnet by Doping with Neodymium
Materials, 2018 The effect of the substitution of Y3+ by Nd3+ on the structural and magnetic properties of neodymium-doped yttrium iron garnet, NdxY3−xFe5O12 with x in the range of 0–2.5, is presented.

Advanced Electronic Materials, EarlyView.Zirconium, hafnium, and mixed zirconium/hafnium doped indium tin oxide thin films are accessible by atomic layer deposition. The amorphous functional films are about 8 nm thick and show a high interdiffusion of all elements. Their transistor characteristics can be modulated depending on the amount of Zr and Hf oxide phases incorporated in these thin ...

High‐Speed Flexible Schottky Diodes Based on Carbon Nanotubes
Advanced Electronic Materials, EarlyView.We demonstrate a flexible Schottky diode based on carbon nanotube network thin film, and the devices are fabricated via a low‐temperature process on a PI substrate, which exhibits excellent radio‐frequency characteristics, with a high responsivity 6 A/W at zero bias, a high intrinsic cut‐off frequency reaching 153 GHz, and an extrinsic cut‐off ...
