Spatiotemporal terahertz emission nanoscopy of spintronic photocurrent

Capturing ultrafast spin and charge photocurrents on nanoscopic scales is essential for fundamental research in physics and engineering, as well as for future applications, such as novel spin-orbitronic devices. Accessing the fundamental dynamics driven by changes in electronic e...

A trick of the tail: How electrostatics helps a DNA repair enzyme to localize on nucleosomes

Electrostatic interactions are key to the recognition processes of proteins and DNA and have been previously documented for the action of repair enzymes. Uracil-DNA glycosylase (UDG) is the first in a sequence of enzymes that act in the base-excision repair process and whose task...

Visible-Light-DrivenPorphyrin/ZnO Nanohybrids forUltrasensitive Room-Temperature Triethylamine Sensing

Abstract Real-time monitoring of toxic triethylamine (TEA) at room temperature remains a significant challenge for metal oxide chemiresistors due to their typically high-power consumption and thermal requirements. This work presents a highly responsive, visible-light-activated ga...
