Effect of air-preheating on NOx emissions from a gas turbine combustor [PDF]
, 1994 A 76 mm diameter can combustor equipped with a 45° curved-blade radial swirler was used to study the effect of high inlet temperature gas turbine combustion on NOx emission characteristics.

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing
Advanced Materials, EarlyView.Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.

Advanced Materials Interfaces, EarlyView.Low‐temperature passivation of SiC reveals that optical surface quality and chemical stability are not directly correlated. Ar plasma‐treated and SiNx‐passivated surfaces yield the lowest photoluminescence background, whereas CF4 plasma and ALD‐grown dielectrics introduce higher emission.

Chemically Doped Conductive Polymers for Wearable Health Monitoring
Advanced Materials Technologies, EarlyView.Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.

Angewandte Chemie, EarlyView.The Sabatier principle and volcano plots declare that optimal electrocatalysis is found in the middle between strong and weak binding of key intermediates. However, it is shown here that during anion electroreduction, strong and weak binding are potential‐dependent concepts and volcanoes are mobile.
