Role of microstructure in porous silicon gas sensors for NO$_2$
, 2003 Electrical conductivity of porous silicon fabricated form heavily doped p-type silicon is very sensitive to NO$_2$, even at concentrations below 100 ppb. However, sensitivity strongly depends on the porous microstructure.

Naked‐Eye Visual Warning of ppmv‐Level Fault‐Free Humidity Upper Limit
Advanced Science, EarlyView.In this study, based on the urgent need in many critical fields for ppmv‐level fault‐free humidity upper limit (ppmv‐FFHUL) monitoring, an innovative threshold gated humidity sensing technology was developed. It exhibits superior portability (as thin and light as paper) and highly economic feature (without auxiliary instruments at all), and can achieve

The NO-NO2 system at laboratory surfaces [PDF]
Experiments on formation and excitation of NO2 and NO molecules at (and near) laboratory surfaces of varying degrees of characterization are reviewed. On some transition metals NO is desorbed in the B sub 2 pi state, from which it radiates the familiar ...

Substituent‐Based Modulation of Self‐Assembly and Immunogenicity of Amphipathic Peptides
Advanced Science, EarlyView.This study systematically investigates how positional and subtle changes, such as substituents on the phenyl ring attached to short amphipathic peptides, influence their self‐assembly, fibril morphology, and immunogenic responses. ABSTRACT Self‐assembled peptide‐based biomaterials provide versatile platforms for biomedical uses, featuring customizable ...
