A Criegee intermediate (also called a Criegee zwitterion or Criegee biradical) is a carbonyl oxide with two charge centers. These chemicals may react with sulfur dioxide and nitrogen oxides in the Earth's atmosphere, and are implicated in the formation of aerosols, which are an important factor in controlling global cl...

In stereochemistry, mutarotation is the change in optical rotation of a chiral material in a solution due to a change in proportion of the two constituent anomers (i.e. the interconversion of their respective stereocenters) until equilibrium is reached. Cyclic sugars show mutarotation as α and β anomeric forms intercon...

One can monitor the mutarotation process over time or determine the equilibrium mixture by observing the optical rotation and how it changes. == Reaction mechanism == == See also == Anomer Carbohydrate Monosacch...

Defoliation bacilli bombs, made between 1932 and 1933, were used by the Imperial Japanese Army to spread bubonic plague across China. The deployment of these lethal munitions provided the Japanese with the ability to launch devastating biological attacks, infecting agriculture, reservoirs, wells and populated areas wit...

The Laser Integration Line (LIL) is a prototype for the Laser Mégajoule (LMJ) located at CEA-CESTA. Whereas the LMJ is planned to comprise 240 laser beams and deliver 1.8MJ, the LIL delivers just one sixtieth of the energy, 30kJ. == References == === Bibliography === == Further reading == Di-Nicola, J.M.; Fleurot, N.; ...

Bacteriophages (phages), potentially the most numerous "organisms" on Earth, are the viruses of bacteria (more generally, of prokaryotes).

in fact it wasn't until the late 1930s through the 1940s that phages were studied, with rigor, as individuals, e.g., by electron microscopy and single-step growth experiments.

which means that the immunity to phages by bacteria has been acquired via adding spacers of DNA that are identical to that of the DNA from the phage. Some phages have been found to be immune to this mechanism as well. In some way or another, the phages have managed to get rid of the sequence that would be replicated. A...

The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it.
