Ether electrolytes for lithium–sulfur batteries
Ether electrolytes for lithium–sulfur batteries are liquid electrolytes built on ether solvents like DME and DOL, widely used because they dissolve polysulfides but suffer from the shuttle effect.
Ether lipid
Ether lipids are glycerolipids with an ether bond at the sn-1 glycerol position, split into alkyl (plasmanyl) and alkenyl (plasmalogen) subclasses; peroxisome-derived, about 20% of mammalian phospholipids, linked to RCDP, Zellweger spectrum, and Alzheimer's disease.
Ether peroxides
Ether peroxides are unstable, shock-sensitive peroxide compounds that form spontaneously when ether solvents such as diethyl ether, THF, and dioxane react with oxygen, concentrating dangerously during distillation.
EtherCAT
EtherCAT (Ethernet for Control Automation Technology) is a real-time Industrial Ethernet technology developed by Beckhoff Automation, standardized in IEC 61158, achieving cycle times of 100 microseconds or less.
EtherChannel
EtherChannel is a Cisco port-trunking technology that bundles multiple physical Ethernet links into a single logical link, providing higher bandwidth and sub-second failover; it predates the IEEE 802.3ad standard, announced by Cisco in 1998.
Ethereum
Ethereum is an open, decentralized blockchain platform for smart contracts and decentralized applications, whose native asset ETH pays for computation and is staked to secure the network.
