Catalytically Enhanced Near Room‐Temperature Hydrogen Sensing Using Pd‐ZnO Colloidal Crystals

Advanced Functional Materials, EarlyView.
Pd‐decorated ZnO colloidal crystal monolayers demonstrate excellent performance across a wide hydrogen concentration range at 33°C, with high selectivity and reproducible device fabrication. The sensors show strong responses even at low‐ppm H2 concentrations and an ultra‐low detection limit of 82 ppb, indicating their suitability for diverse hydrogen ...

Reactive Power Compensation Using Induction Motor Driven by Nine Switch AC-DC-AC Converter

IEEE Access, 2018
Induction motors (IM) used for various industrial applications operate with lagging power factor. Electrical distribution agency insists high power factor operation and it gives incentives on operating a system closer to unity.

Performance Analysis of Shunt Reactive Power Compensators

2009 Third Asia International Conference on Modelling & Simulation, 2009
This paper offers comparative solutions for utility companies to solve the problem of voltage flicker in distribution systems. The solutions entail provision of shunt reactive compensation. Two solutions will be explored: the shunt capacitor and the Static VAR Compensator (SVC). Both solutions are modeled and simulated using PSCAD.

Reconstructing Quantum Dot Surfaces via Dual‐Functional Ligand Pairing Enables Efficient Shortwave Infrared Optoelectronics

Advanced Functional Materials, EarlyView.
This work presents a ligand‐pairing strategy that reconstructs lead sulfide quantum dot surfaces for efficient short‐wave infrared optoelectronics. A low‐reactivity thiourea precursor combined with hydrobromic acid enables monodisperse and fully passivated quantum dots.

Simultaneous Enhancement of Performance and Stability in Dual‐Gate a‐IGZO Thin‐Film Transistors via Single‐Step Laser Annealing for Capacitor‐Less DRAM

Advanced Functional Materials, EarlyView.
A single‐step laser annealing strategy is presented for dual‐gate a‐IGZO TFTs. The steep thermal gradient induces graded oxygen doping in the channel and simultaneous WOx removal at the contacts, enabling concurrent interface and contact engineering.
