Constructing Success in the Electric Power Industry: Flexibility and the Gas Turbine [PDF]
This paper explains the success and failure of two technologies that generate electricity from fossil fuels. Both the Combined Cycle Gas Turbine (CCGT) and fluidised bed boiler burn fossil fuels more cleanly than more traditional technologies.

Graphene‐Based Wearable Textile Triboelectric Nanogenerators and Biomechanical Sensors
Advanced Materials Technologies, EarlyView.This study presents a wearable textile‐based triboelectric nanogenerator (T‐TENG) using sprayed graphene enhanced with a PVA adhesion layer. The graphene‐based electrode demonstrates high electrical conductivity and robustness to multiple bends. The fabricated T‐TENG provides stable and efficient output, with strong responsiveness to biomotion.

Ultra‐Flexible Dual‐Band Organic Photodetectors for Visible and Near‐Infrared Sensing
Advanced Optical Materials, EarlyView.An ultra‐flexible dual‐band organic photodetector with a total thickness of 5.6 µm for bio‐sensing is developed. It selectively detects visible and near‐infrared light with high sensitivity by switching the voltage. Peripheral oxygen saturation (SpO2) measurement is demonstrated using the device attached to a finger under a single light source by ...
