The activator is the main factor determining the phosphor emission wavelength. The nature of the host crystal can however to some degree influence the wavelength as well. More activators can be used simultaneously.
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 ]
Sirtuin-activating compounds (STAC) are chemical compounds having an effect on sirtuins, a group of enzymes that use NAD+ to remove acetyl groups from proteins. They are caloric restriction mimetic compounds that may be helpful in treating various aging -related diseases.
[2] [3] [4] The activity of activators is controlled by the ability of the activator to bind to its regulatory site along the DNA. [2] [3] [4] The DNA-binding domain of the activator has an active form and an inactive form, which are controlled by the binding of molecules known as allosteric effectors to the allosteric site of the activator.

[6] Drugs in the oxime class (e.g., Pralidoxime) reactivate AChE by removing the OP. Oximes have a higher affinity for phosphorylation than the serine residue in the AChE active site, causing the OP to detach from the AChE enzyme, freeing its active site and restoring function.

2Na 2 CO 3 ∙3H 2 O 2 → 2Na 2 CO 3 + 3H 2 O 2. In a basic wash solution, hydrogen peroxide loses a proton and is converted to the perhydroxyl anion: H 2 O 2 ⇌ H + + HO 2 −. The perhydroxyl anion then attacks the activator, forming a peroxy acid: HO 2 − + RC(O)X → X − + RC(O)O 2 H
An activation product is a material that has been made radioactive by the process of neutron activation.. Fission products and actinides produced by neutron absorption of nuclear fuel itself are normally referred to by those specific names, and activation product reserved for products of neutron capture by other materials, such as structural components of the nuclear reactor or nuclear bomb ...
