Design of Fission Chamber Pulse Pre-amplifier

Journal of Isotopes
Fission chambers are installed in the measurement channels within the reactor and the signals are transmitted via inorganic and organic cables. They can be used for monitoring the neutron flux of the reactor from startup to full power operation.

Oxygen Partial Pressure as a Kinetic Descriptor for Single‐Crystal Morphology in Mid‐Nickel Layered Cathodes

Advanced Science, EarlyView.
Scalable synthesis of single‐crystal mid‐nickel cathodes demands precise kinetic control over competing densification and grain growth. Oxygen partial pressure emerges as a quantitative descriptor of effective grain‐boundary mobility, acting through changes in the apparent sintering activation barrier.

Neutron Depth Profiling: The Core Link Connecting the Microscopic Mechanisms of Lithium‐Ion Batteries With Intelligent Design

Advanced Science, EarlyView.
Neutron depth profiling exploits the 6Li(n,3H)4He reaction to provide quantitative, isotope‐specific, depth‐resolved maps of lithium inside operating lithium‐ion batteries, directly linking lithium transport, dendrite growth and interfacial short‐circuiting to a physics‐informed machine‐learning roadmap that turns this non‐destructive operando ...

Rational Surface Engineering Reduces Advanced Glycation End‐Product Adsorption and Improves Implant Integration

Advanced Science, EarlyView.
Targeted surface chemical modification prevents the accumulation of advanced glycation end products (AGEs) on implant surfaces, attenuates inflammation and fibrosis, effectively restores angiogenic activity, and improves osseointegration under diabetic conditions.

A Multimodal Piezoelectric Vertical Sidewall Architecture for Scalable In‐Plane NEMS Resonators

Advanced Electronic Materials, EarlyView.
A vertical in‐plane piezoelectric resonator design shifts frequency tuning from film thickness to lithographic lateral definition, facilitating monolithic multiband integration. Initially validated via microscale length‐extensional resonators, this cavities‐first fabrication approach scales to the nanoscale for high‐frequency operation.

Noise Reduction Design of the Transformer and the Reactor

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 2006
The purpose of this study is to solve the noise level caused by the transformer and reactor covered by the double covers, and to reduce the noise increased by the resonance of the wall. To research the phenomenon of the sound in the box, firstly, we simulated the vibration coupled noise analysis of a reactor, its double covers, and their air gaps by ...
