High‐Performance and Ultrafast Single Germanium Nanowire Photodetectors

open access: yesAdvanced Optical Materials, EarlyView.
Semiconductor nanowire‐based photodetectors with high sensitivity and fast photoresponse in the near‐infrared wavelength range are crucial for applications in light‐wave communication switches, as well as environmental and atmospheric sensing. Here, the fabrication of an axial p‐n junction along single germanium nanowires and their photoresponse ...

Structure‐Guided Engineering of Oleate Hydratase for the Synthesis of Small Chiral Alcohols without Decoy Molecule

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract Small and chiral secondary alcohols are sought‐after compounds that are frequently used in the synthesis of biologically active compounds. However, their stereochemically correct synthesis remains a challenge for the chemical industry. Synthetic routes are restrained by multiple steps and thus low atom efficiency.
