USING BALL MILLING FOR MODIFICATION OF THE HYDROGENATION/DEHYDROGENATION PROCESS IN MAGNESIUM-BASED HYDROGEN STORAGE MATERIALS: AN OVERVIEW

Using Ball Milling for Modification of the Hydrogenation/Dehydrogenation Process in Magnesium-Based Hydrogen Storage Materials: An Overview

Magnesium-based hydrogen storage materials are considered to be one of the most promising solid-state hydrogen storage materials due to their large hydrogen storage capacity and low cost.However, slow hydrogen absorption/desorption rate and excessive hydrogen absorption/desorption temperature limit the application of magnesium-based hydrogen storag

Direct nonlinear acceleration

Optimization acceleration techniques such as momentum play a key role in state-of-the-art machine learning algorithms.Recently, generic vector sequence extrapolation techniques, such as regularized nonlinear acceleration (RNA) of Scieur et al.[22], were proposed and shown to accelerate fixed point iterations.In contrast to RNA which computes extrap
