Compatibility study between CLF-1 steel and HCCB TBM Helium gas medium for engineering qualification

Focusing on engineering qualification, a compatibility test between CN HCCB-TBM structural material CLF-1 steel and cooling gas medium (He + 30 ppm H 2 ) is presented in this study. The CLF-1 specimens are contacted with a mixed gas at a temperature of 823 K and pressure of 8 MPa...

Fe-mediated phase evolution and defect regulation in flexible Cu2Se films for enhanced thermoelectric transport

The monoclinic copper selenide (α-Cu2Se) is a promising thermoelectric (TE) material due to its ordered Cu sublattice and intrinsically low thermal conductivity for near-room-temperature applications. However, excessive Cu vacancies in α-Cu2Se lead to carrier overconcentration an...

Design of a Pop-Up Divertor Langmuir Probe System for the HL-3 Tokamak

A novel pop-up divertor Langmuir probe system is developed for measuring the plasma parameters on divertor target plates in HL-3 tokamak. The system enables reliable ejection and retraction in strong magnetic-field environments and adopts a modular design consisting of a probe as...

Se4+-Doped Indium-Based Perovskites via NaCl-Driven Structural Transformation for Dynamic Luminescence Modulation in Multimodal Anti-counterfeiting and Encryption

Abstract The growing risks of counterfeiting and information security breaches have spurred the demand for high-security stimuli-responsive optical materials. However, many reported materials exhibit discontinuous luminescence switching or require harsh external stimuli. Herein,...

Rydberg-Atom-Based Angle-of-Arrival Estimation Method for Ku-Band Microwave Signals

The determination of the angle of arrival (AoA) of Ku-band microwave signals is of great significance in satellite communications, spectrum monitoring, and national defense security, which has created an urgent demand for high-precision and interference-resistant passive detectio...
