Piezoelectric Polyurethane/Barium Titanate Composites with High Stretchability and Voltage Output for Energy Harvesting in Soft Wearable Electronics

Advanced Materials Technologies, EarlyView.
Piezoelectric additives are combined with an elastomer host, creating a material with properties of both parent materials: high voltage output and exceptional stretchability. These stretchable piezoelectric materials have the robustness for integration into soft wearable electronics, functioning as renewable energy harvesters to charge capacitors.

Origin of the Laser‐Induced Picosecond Spin Current Across Magnetization Compensation in Ferrimagnetic GdCo

Advanced Optical Materials, EarlyView.
Picosecond spin current pulses generated by ferrimagnetic GdCo are studied via THz emission spectroscopy. Due to the GdCo micromagnetic structure, the spin current vanishes at compensation when a magnetic field is applied but persists for zero field. At room temperature, the THz spin current is dominated by Co. At low temperatures, Gd can significantly

Comprehensive genetic screening for vascular Ehlers–Danlos syndrome through an amplification‐based next‐generation sequencing system

American Journal of Medical Genetics Part A, Volume 191, Issue 1, Page 37-51, January 2023., 2023
Abstract Vascular Ehlers–Danlos syndrome (vEDS) is a hereditary connective tissue disorder (HCTD) characterized by arterial dissection/aneurysm/rupture, sigmoid colon rupture, or uterine rupture. Diagnosis is confirmed by detecting heterozygous variants in COL3A1.
