On the category of oxidative addition, M. L. H. Green in 1970 reported on the photochemical insertion of tungsten (as a Cp 2 WH 2 complex) in a benzene C–H bond [7] and George M. Whitesides in 1979 was the first to carry out an intramolecular aliphatic C–H activation [8] Fujiwara's palladium- and copper-catalyzed C-H functionalization
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.
68 Ga III is usually obtained from a dedicated mobile radionuclide source, a Gallium-68 generator, in form of a solution in dilute (0.04–0.1 M) hydrochloric acid (frequently and imprecisely referred to as "68 Ga chloride solution in HCl" despite it contains no species with a Ga–Cl bond but [68 Ga(H 2 O) 6] 3+ complex hydrate cations).

[1] [2] As a liquid, it is easier to handle than the commonly used N,N ′-dicyclohexylcarbodiimide, a waxy solid. In addition, N , N ′ -diisopropylurea, its byproduct in many chemical reactions, is soluble in most organic solvents , a property that facilitates work-up .
NOBS is the main bleach activator used in the U.S.A. and Japan. [4] Compared to TAED , which is the predominant bleach activator used in Europe, NOBS is efficient at much lower temperatures. At 20 °C NOBS is 100 times more soluble than TAED in water. [ 5 ]
Surface activation prior to bonding by using fast atom bombardment is typically employed to clean the surfaces. High-strength bonding of semiconductors, metals, and dielectrics can be obtained even at room temperature. [1] [2]
The N-terminal acts as an allosteric regulator of C-terminal; the C-terminal is the only one involved in the catalytic activity. HK-I is regulated by the concentration of G6P, where G6P acts as a feedback inhibitor. At low G6P concentration, HK-I is activated; at high G6P concentration, the HK-I is inhibited. [1]
The loops connecting the beta-strands differ greatly in length, making the PH domain relatively difficult to detect while providing the source of the domain's specificity. The only conserved residue among PH domains is a single tryptophan located within the alpha helix that serves to nucleate the core of the domain.
