Neutral‐pH Electropolymerization of Aniline on Hierarchically Porous Laser‐Induced Graphene Electrodes for Dual Biosensing

open access: yesAdvanced Materials Technologies, EarlyView.
Neutral‐pH electropolymerization of aniline on laser‐induced graphene (LIG) produces stable, brush‐like polyaniline coatings without requiring acidic conditions. The resulting PANI–LIG electrodes exhibit enhanced electroactive surface area, efficient charge transfer, and dual sensing capability for β‐blockers and pH, providing a scalable platform ...

Alternative Refrigerants For Household Refrigerators

open access: yes, 2018
During the last decades, the energy consumption of household appliances was reduced continuously. The reason for this developments is caused by higher power costs and stricter statutory rules. To achieve these goals, it was necessary to improve and evolve each component of the cooling circuit as well as the insulation.

Design and Utilization of Stable Hydrofluoroolefin‐Based Trifluoropropynyl Surrogate for Sonogashira Coupling

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A novel methodology for the construction of aromatic and heteroaromatic trifluoropropynyl derivatives has been developed. The new protocol is based on a tandem Sonogashira cross‐coupling reaction between a bench‐stable trifluoropropynyl carbinol reagent, generated from the commercially available and inexpensive hydrofluoroolefin‐1234yf gas, and (hetero)

Microbial Contribution to Soiling and Its Impact on Photovoltaic Module Soiling in Arid Zones of the Atacama Desert

open access: yesAdvanced Sustainable Systems, EarlyView.
Microorganisms colonizing photovoltaic surfaces in the Atacama desert form biofilms that enhance particle adhesion and reduce energy yield. This study identifies UV‐resistant bacteria and carotenoid‐producing strains that interfere with PV performance.
