Revealing a Pathway for Low‐Temperature Recrystallization in Germanium
Advanced Science, EarlyView.This study reports the discovery that energy transferred to electrons and atoms by highly ionizing ions results in a disorder‐order (amorphous‐crystalline) phase transformation in noncrystalline (amorphous) Ge. This discovery unlocks low‐temperature recrystallization pathways in Ge, offering a nonthermal strategy for fabricating Ge‐based devices that ...

Innovative Approach to Recycle Lithium‐Ion Battery Electrolytes via Sequential Chemical Processes
Advanced Energy Materials, EarlyView.A chemical separation method is developed to recycle and purify nonaqueous electrolytes from spent lithium‐ion batteries. The new process consists of a sequence of precipitation in tandem with each distillation and solvent‐assisted vacuum extraction to obtain high‐quality electrolyte precursors.

Intent Arabic text categorisation based on different machine learning and term frequency
IET Networks, EarlyView., 2022 Abstract The complexity of Internet network configurations has made managing networks a complicated undertaking. Intent‐Based Networking (IBN) is a potential solution to this issue. In contrast to conventional networks, where a concrete description of the settings typically conveys a network administrator's goal kept on each device, an administrator's ...
