Intimate Interaction Between Nucleic Acid and Conjugated Polymers in Organic Electrochemical Transistors Enables Ultrasensitive Biomarker Detection

Advanced Materials, EarlyView.
The intimate interaction between negatively charged RNA molecules and conjugated polymers in organic electrochemical transistors (OECTs) in aqueous electrolytes is investigated. It demonstrates that RNA binding reduces the volumetric capacitance of the polymer channel, enabling the development of an ultrasensitive biosensing platform capable of ...

Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

Advanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...

Operation Limits of Integrated Photo‐Rechargeable Batteries

Advanced Materials, EarlyView.
This study elucidates the operational limitations of integrated photo‐rechargeable batteries. We demonstrate that the photo‐charging process is fundamentally restricted not only by material‐to‐material energy level alignment but also by transient capacitive charge accumulation within the cathode framework.

Modelling the steady state and dynamic conditions of a biotrickling filter treating styrene and acetone in air

Brazilian Archives of Biology and Technology, 2010
The aim of this work was the study a trickling biofilter, where water was circulated throughout the bed. In the first steady state experiment, the packing materials used were 25mm Pall rings. The airflow rate was increased gradually and the concentration
