56exchange-correlation (XC) functional, which has been used in this work, is known to underestimate adsorption energies and overestimate adsorption distances in many cases57,58,59. To assess the effect of the choice of XC functional, surface structures were reoptimized, and adsorption energies rec...
Mixed ethers are those with different R groups—for example, C5H11OCH2C6H5 (amyl benzyl ether). Some ethers have trivial names, such as anisole (CH3OC6H5, the methyl ether of phenol) and cellosolves (the monoethers of ethylene glycol). As a rule, ethers are poorly soluble in water ...
For example, 18-crown-6 (Fig. 19.19) has high affinity for K+, 15-crown-5 for Na+, and 12-crown-4 for Li+. Like valinomycin, the exterior of the ring is hydrophobic, allowing crown ethers to dissolve in the membrane lipid bilayer while carrying the sequestered cation down its ...
Step 1: Identify the longest carbon chain and highlight it as the parent chain. There are always two side chains in ethers {eq}R-O-R {/eq}, the longest of these two side chains is the parent chain. Use the alkane base name to write the name of the parent chain. Example: for a...
For example, PFPE is a perfluoro(poly)ether group, X is a substituted or unsubstituted alkylene group having 2 to 20 carbon atoms, Ris a functional group comprising a Si, Ris a hydrogen atom or a lower alkyl group, k is an integer of 1 to 3, 1 and m are an integer of 0 to 2...
Example: Device(config-if)# no ip address Disables the IP address if the Fast Ethernet interface already exists and has an IP address assigned. Step 5channel-groupchannel-number Example: Device(config-if)# channel-group 3 Assigns Fast Ethernet interfaces to the Fast EtherChannel. The channel ...
A colorless liquid used as a solvent, in detergents, and as a diluent; a typical example is ethylene glycol diethyl ether, C2H5OCH2CH2OC2H5.McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc. ...
The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert. Hazard Toxic on prolonged inhalation. Flammable, moderate ...
As shown in the test results of Examples 1 to 3 and Comparative Example, when the molecular mass of the PPE is lower, a main chain PPE in the PPE-BX is shorter, and the PPE has low dielectric properties (low Dk and low Df). Therefore, a PPE structure chain is shorter, and an ele...
Polyoxyethylene with sugar by one end and other functional group by other end and method of its synthesis aralkyl or aryl; X means a single bond or -CH 2 -CH 2 -; Z means group forming unsaturated ester or ether or functional group, for example, halogen atom that is bound with -CH ...
