C 3 S 2 was discovered by Béla Lengyel , [2] who assigned it an unsymmetrical structure. Later, infrared and Raman spectroscopy showed that the structure is symmetrical with a D ∞h point group symmetry, [3] i.e. S=C=C=C=S. This compound is analogous to carbon suboxide whose structure is O=C=C=C=O.
There are also reports of harms to health at 10 mg/m 3, for exposures of 10–15 years, but the lack of good data on past exposure levels make the association of these harms with concentrations of 10 mg/m 3 findings uncertain. The measured concentration of 10 mg/m 3 may be equivalent to a concentration in the general environment of 1 mg/m 3. [28]
What Is Life? The Physical Aspect of the Living Cell is a 1944 science book written for the lay reader by the physicist Erwin Schrödinger.The book was based on a course of public lectures delivered by Schrödinger in February 1943, under the auspices of the Dublin Institute for Advanced Studies, where he was Director of Theoretical Physics, at Trinity College, Dublin.
BIOS-3 is an experimental closed ecosystem at the Institute of Biophysics in Krasnoyarsk, Russia.. Its construction began in 1965, and was completed in 1972. BIOS-3 consists of a 315 cubic metres (11,100 cu ft) underground steel structure [1] suitable for up to three persons, and was initially used for developing closed ecological human life-support ecosystems.
Description: This book explained Dalton's theory of atoms and its applications to chemistry. Importance: The book was one of the first to describe a modern atomic theory, a theory that lies at the basis of modern chemistry. [3]: 251 It is the first to introduce a table of atomic and molecular weights.
It has been shown that carbon suboxide in an organism can quickly polymerize into macrocyclic polycarbon structures with the common formula (C 3 O 2) n (mostly (C 3 O 2) 6 and (C 3 O 2) 8), and that those macrocyclic compounds are potent inhibitors of Na + /K +-ATP-ase and Ca-dependent ATP-ase, and have digoxin-like physiological properties and ...
CCS can be a ligand. It can form an asymmetrical bridge between two molybdenum atoms in Mo2(μ,σ(C):η 2 (C′S)-CCS)(CO) 4 (hydrotris(3,5-dimethylpyrazol-1-yl)borate) 2 In this one carbon atom has a triple bond to a molybdenum and the other has a double bond to the other molybdenum atom, which also has a single bond to the sulfur atom.
C2 domain, a protein structural domain; C2 regulatory sequence for the insulin gene; Apolipoprotein C2, a human apolipoprotein; In human anatomy, C2 may refer to: Cervical vertebra 2, the axis, one of the cervical vertebrae of the vertebral column
