Resolving the High‐k Paradox in Organic Field‐Effect Transistors Through Rational Dielectric Design

Advanced Electronic Materials, EarlyView.
High‐k dielectrics are in great demand for developing organic transistors operating at low voltages. However, the actual influence of high‐k dielectrics has been ambiguous. This work clarifies the correlation of dielectric constant and mobility through highly miscible high‐k polymer blends and provides a rational strategy on designing high‐performance ...

Scalable and Integrated Photocatalytic Reactor Systems for Solar‐to‐Fuel Production: Photoredox and Photoreforming Processes

Advanced Energy Materials, EarlyView.
Solar fuels and other value‐added chemicals derived from light‐driven reactions are highly desirable. Although advanced photoactive materials have been reported, demonstrations of their feasibility in large‐scale production are needed. Hence, strategies and recent efforts in scaling up photocatalytic reactors and integrating them into comprehensive ...

Occupational exposures in the operating room: Are surgeons well-equipped?

PLoS ONE, 2021
BackgroundOccupational health hazards are ubiquitously found in the operating room, guaranteeing an inevitable risk of exposure to the surgeon. Although provisions on occupational health and safety in healthcare exist, they do not address non-traditional

Zinc Grid Based Transparent Electrodes for Organic Photovoltaics

Advanced Energy Materials, EarlyView.
A transparent flexible electrode based on an embedded zinc grid with ≈1 µm linewidth is reported, and its utility as a drop‐in replacement for indium‐tin oxide coated glass electrodes in organic photovoltaic devices is demonstrated. The zinc grids are fabricated using the unconventional approach of condensation coefficient modulation, using a ...

Exposure to Methylmethacrylate in an Orthopaedic Operating Theatre [PDF]

Occupational Medicine, 1996
Methylmethacrylate (MMA) bone cement is an acrylic plastic polymer used by orthopaedic surgeons in joint replacement surgery. It is reconstituted in the operating theatre, immediately prior to its use, by mixing liquid acrylic monomer with powdered polymer. MMA monomer is a recognized irritant and sensitizing agent.

Engineering von Transmembran‐Alkan‐Monooxygenasen zur Verbesserung des Schlüsselschritts in der Biosynthese des Polymervorläufers Tulipalin A

Angewandte Chemie, EarlyView.
Ein Biosyntheseweg für den Polymervorläufer Tulipalin A ausgehend von Isoprenylacetat wird hier präsentiert. Die Alkan‐Monooxygenase AlkB katalysiert die chemo‐ und regioselektive terminale Hydroxylierung von Isoprenylacetat und die Aktivität konnte durch rationelles Engineering des Membranenzyms weiter gesteigert werden. Die vollständige Oxidation zur
