Silicene is a two-dimensional allotrope of silicon, with a hexagonal honeycomb structure similar to that of graphene
Contrary to graphene, silicene is not flat, but has a periodically buckled topology; the coupling between layers in silicene is much stronger than in multilayered graphene; and the oxidized form of silicene, 2D silica, has a very different chemical structure from graphene oxide. History Al
Albumen prints and egg whites…all the rage back in the day…and a few other things
The albumen print, also called albumen silver print, was published in January 1847 by Louis Désiré Blanquart-Evrard, and was the first commercially exploitable method of producing a photographic print on a paper base from a negative. It used the albumen foun
p-Phenylenediamine (PPD) is a derivative of aniline used in kevlar, hair dye and henna substitutions among other things, the derivatives of which are used in antiozonants among other horrors
p-Phenylenediamine (PPD) is an organic compound with the formula C6H4(NH2)2. This derivative of aniline is a white solid, but samples can darken due to air oxidation.It is mainly used as a component of engineering polymers and composites like kevlar. It is also an ingredient in hair dyes a
Zinc, maybe
No proof for the need of zinc in human cells was shown until the late 1930s. More than most ever wanted to know about zinc. A work in progress.
Cyanamide notes (it was a polio vaccine that spurred these notes and by now polio has five mentions on the page and these are two of them)
I’m going to add some polio vaccine stuff at the top of these notes. Hilary Koprowski is the one mentioned on the Polio Hall of Fame page who was not included in the hideous monument, see What In God’s Name, even though he (and his work) have direct connection to those who are included.
Basil O’Connor (1892 â 1972) was an American lawyer
In cooperation with U.S. President Franklin D. Roosevelt he started two foundations for the rehabilitation of polio patients and the research on polio prevention and treatment. From 1944 to 1949 he was chairman and president of the American Red Cross and from 1945 to 1950 he was chairman of the Leag

Catecholamine (CA)
A catecholamine (abbreviated CA) is a monoamine neurotransmitter, an organic compound that has a catechol (benzene with two hydroxyl side groups next to each other) and a side-chain amine. Fitzgerald, P. A. (2011). “Chapter

Baccharis is a genus of perennials and shrubs in the aster family (Asteraceae)
They are commonly known as baccharises but sometimes referred to as “brooms”, because many members have small thin leaves resembling the true brooms. They are not at all related to these however, but belong to an entirely different lineage of eudicots. B. halimifolia is commonly kn
