N,N′-Dicyclohexylcarbodiimide (DCC or DCCD) [1] is an organic compound with the chemical formula (C 6 H 11 N) 2 C. It is a waxy white solid with a sweet odor. Its primary use is to couple amino acids during artificial peptide synthesis. The low melting point of this material allows it to be melted for easy handling.
Dynamic carrier control (DCC) is a method of reducing power consumption in radio transmitters during periods of low audio activity or silence. It is a type of Modulation-Dependent Carrier Level control, or MDCL. All modern high-power (>50 kW) shortwave radio transmitters incorporate DCC of some kind, as well as some mediumwave (MW) transmitters.
It is an adaptation of an older method for the formation of amides by means of DCC (dicyclohexylcarbodiimide) and 1-hydroxybenzotriazole (HOBT). [2] [3] Steglich overview. This reaction generally takes place at room temperature. A variety of polar aprotic solvents can be used. [4]
Dicyclohexylurea is an organic compound, specifically, a urea.It is the byproduct of the reaction of dicyclohexylcarbodiimide with amines or alcohols.It may be prepared by the reaction of cyclohexylamine and S,S-dimethyl dithiocarbonate.
A similar non-standard notation using the unit symbol instead of a decimal separator is sometimes used to indicate voltages (i.e. 0V8 for 0.8 V, 1V8 for 1.8 V, 3V3 for 3.3 V or 5V0 for 5.0 V [24] [25] [26]) in contexts where a decimal separator would be inappropriate (e.g. in signal or pin names, in file names, or in labels or subscripts).
The N=C=N core is relatively linear and the C-N=C angles approach 120°. In the case of C(NCHPh 2) 2, the central N=C=N angle is 170° and the C-N=C angles are within 1° of 126°. [5] The C=N distances are short, nearly 120 pm, as is characteristic of double bonds. Carbodiimides are chiral, possessing C 2-symmetry and therefore axial chirality ...

GCC1/2 – four bytes (each of two bytes) within ODUk overhead. These bytes are used for client end-to-end information and shouldn't be touched by the OTN equipment. In contrast to SONET/SDH where the data communication channel (DCC) has a constant data rate, GCC data rate depends on the OTN line rate. For example, GCC0 data rate in the case of ...
