Business Process Reengineering of Outage Management at X Electric Power Supply Company [PDF]

open access: yes, 2014
随着电网日新月异的发展,人财物集约化、管理架构扁平化的管理思路转变,X供电公司电力设备停运管理低效运作的现状与电网飞速发展及组织架构大刀阔斧的变革产生强烈的冲突。国外发达国家模式无法适用,国内供电公司无经验可借鉴,提升停运管理效率需另辟蹊径。本文首先对业务流程再造理论进行了回顾。然后,对X供电公司现状,造成停电管理效率不高的内外因素进行了分析,揭示了管理流程中存在的问题,并深入分析了产生这些问题的根源。再次,比对国外发达国家先进模式,思考借鉴其模式进行流程再造的可能。在完成可行性分析基础上 ...

Bi/Bi2O3 Nanoparticles In Situ Embedded in Carbon as Anode Materials for Fast and Long‐Lasting Sodium–Ion Storage

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Bismuth anode materials are considered promising anode candidates for sodium–ion batteries (SIBs) due to their high theoretical capacity and appropriate working potential. Nevertheless, the significant volume expansion that occurs during the cycling process restricts its broader application in sodium–ion storage. Herein, Bi/Bi2O3 nanoparticles
