Application of electro-active biofilms [PDF]
, 2010 The concept of an electro-active biofilm (EAB) has recently emerged from a few studies that discovered that certain bacteria which form biofilms on conductive materials can achieve a direct electrochemical connection with the electrode surface using it ...

Advanced Engineering Materials, EarlyView.Bimetallic (NiFe) and trimetallic (NiFeCr) nanoalloys (NAs) are synthesized using corresponding oxide mixtures using microwave hydrogen plasma within a few milliseconds. The process simultaneously 1) reduces metal oxides to metals; 2) downsizes the particles from micrometers to nanometers; and 3) blends the metals to form NAs.

First-Principles Algorithm for Air Quality Electrochemical Gas Sensors [PDF]
ACS Sensors, 2020 We report here a simple approach that allows for rapid mapping of raw voltage readings to concentrations for parts-per-billion level air quality electrochemical sensors. The key step is the introduction of an auxiliary sensor and then covering it with a thin Nafion membrane, one that is well-known for its both highly efficient and selective permeation ...

Combined electronic nose and tongue for a flavour sensing system [PDF]
, 2011 We present a novel, smart sensing system developed for the flavour analysis of liquids. The system comprises both a so-called "electronic tongue" based on shear horizontal surface acoustic wave (SH-SAW) sensors analysing the liquid phase and a so-called "

Advanced Functional Materials, EarlyView.This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.
