N‐Containing Carbon Materials in Metal‐Free and Non‐Noble Metal Liquid Phase Heterogenous Catalysis

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Over 100 examples of non‐noble metal supported on N‐containing and metal‐free N‐containing carbon catalysts are discussed. Particular emphasis is put on how different N‐functionalities influence catalyst performance and stability. Preparation procedures are also examined, with a strong focus on how the heat treatment temperature influences N ...

Development of f‐ELISA Sensors with Ultrahigh Sensitivity for On‐Site Colorimetric Detection of Fentanyl and Norfentanyl

open access: yesAdvanced Sensor Research, EarlyView.
A foam‐based ELISA (f‐ELISA) platform was developed using chemically modified melamine foam to enable rapid, ultrasensitive, and selective colorimetric detection of fentanyl and norfentanyl. Abstract Rapid and accurate detection of fentanyl in unknown products and aqueous samples can find the unexpected existence of the toxic chemical and assist law ...

3D‐Printed Macroporous Resin Anode in Microbial Fuel Cell‐Based Biosensors for Efficient Biodegradable Organic Carbon Monitoring

open access: yesAdvanced Sensor Research, EarlyView.
This study presents a 3D‐printed gyroid resin anode for microbial fuel cell biosensors. Compared with carbon felt, it enables either a broader dynamic range or higher sensitivity, depending on the operation mode. By improving real‐time monitoring of organic load, these biosensors support more efficient process control and contribute to the goal of ...
