Nanoscale Diamane Spiral Spring for High Mechanical Energy Storage (Small 38/2022)

High-energy Cyclotrons without Spiral

This paper explores the possibility of reaching high energies in isochronous ring cyclotrons with radial sectors by using negative valley fields to increase the magnetic flutter. A simple model was used to generate field maps for 4-GeV and 13-GeV proton rings, whose orbit properties were then studied using the CYCLOPS equilibrium orbit code. Field maps were also generated for two FFAG designs (...

Hybrid Hydrogen and Mechanical Distributed Energy Storage

Effective energy storage technologies represent one of the key elements to solving the growing challenges of electrical energy supply of the 21st century. Several energy storage systems are available, from ones that are technologically mature to others still at a research stage. Each technology has its inherent limitations that make its use economically or practically feasible only for specific...

Storage Management for High Energy Physics Applications

In many scientific domains large volumes of data are often generated by experimental devices or simulation programs. Examples are atmospheric data transmitted by satellites, climate modeling simulations, and high energy physics experiments. The volumes of data may reach hundreds of terabytes and therefore it is impractical to store them on disk systems. Rather they are stored on robotic tape sy...

Energy Storage: Battery Materials and Architectures at the Nanoscale

High-efficiency mechanical energy storage and retrieval using interfaces in nanowires.

By molecular dynamics simulations, we demonstrate a new concept for mechanical energy storage and retrieval using surface energy as reservoir in body-centered cubic (bcc) tungsten nanowire, achieving a combination of unique features such as large and constant actuation stress (>3 GPa), exceptionally large actuation strain (>30%) and energy density, and >98% energy storage efficiency. The underl...
