A Modular Biosensor Platform for the Detection of Plastic Monomers and the Engineering of Promiscuous Amidases Toward Challenging Substrates

open access: yesAdvanced Science, EarlyView.
A luciferase is used as biosensor for aldehydes, produced enzymatically from different monomeric building blocks of plastics like polyurethanes (PUs). The screening platform is used to monitor esterase, amidase, and urethanase activity and to guide the selection of enzyme variants with improved hydrolytic activities toward difficult to hydrolyze ...

From CO2 to C1 Liquid Fuels: Molecular Electrochemical Production of Formic Acid and Methanol

open access: yesAngewandte Chemie, EarlyView.
Sustainable transformation of CO2 into formic acid and methanol is key to circular carbon economies and sustainable energy. These liquid C1 products are high in energy density, easy to store, and serve as hydrogen carriers and feedstocks. Electrochemical CO2 reduction provides a promising route for carbon recycling and renewable energy integration ...

Stretchable Energy Storage with Eutectic Gallium Indium Alloy

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
A highly stretchable liquid metal‐based electrode is developed via a one‐step process, retaining conductivity and capacitance after mechanical deformation up to 900% strain. The stretchable all‐solid‐state device provides a areal energy density of 43 µWh cm⁻2 after 150% strain.

Harnessing Solar Energy for Ammonia Synthesis from Nitrogen and Seawater Using Oxynitride Semiconductors

open access: yesAdvanced Energy Materials, EarlyView.
In this work, the challenging green ammonia evolution is addressed by developing a photothermal system that utilizes nitrogen and natural seawater under simulated solar irradiation, employing ruthenium‐doped barium tantalum oxynitride semiconductors.
