This work reviews factors which are important for the evolution of habitable Earth-like planets such as the effects of the host star dependent radiation an
Aramid, short for "aromatic polyamide," is a class of synthetic, high-performance fibers. Meta-aramid fibers were first commercially applied in the early 1960s, with para-aramid fibers being developed in following decade. They are unique because their structures, characterized by polymer chains, ...
There is a single hydroxyl group para-substituted in an aromatic ring that is linked to a side chain conjugate. This substitution allows the phenoxy radical free electrons to become delocalized over the entire molecule, and therefore stable. The ortho substitution to the methoxy group, an electron...
What is an aromatic compound? Aromatic Compounds: Aromatic Compounds follow the Hackle's rule according to which a ring is aromatic if it has the property called planarity, delocalization of theπelectrons in the ring and there should be(4n+2)π(where n is a whole number) electrons present ...

People talk a lot about “cures” in the health industry but there’s a saying you probably heard from your grandparents that makes a lot more sense… “An ounce of prevention is worth a pound of cure.” At The Truth About Cancer we talk a lot about what causes cancer, and the foods...
aMaximum protection was shown in compounds having electron- withdrawing substituents on the aromatic and heterocyclic ring at the 5th position of triazole ring. 最大保护在化合物在芳香和杂环圆环显示了有电子撤出代替者在三氮二烯伍圆圆环的第5个位置。[translate] ...
An Adenine base Cytosine (C):Cytosine is a pyrimidine with the chemical compound C4H5N3O. A cytosine-based nucleotide is called acytosine. Cytosine is a heterocyclic aromatic ring with two substituents attached. Cytosine pairs with guanine to form nucleic acid, but as a free nucleotide can wor...
PETG’s structure, like ABS, is resistant to biodegradation due to its strong ester bonds and aromatic rings, which are stable in most environmental conditions. This makes PETG durable but not biodegradable. On the other hand, both ABS and PETG can be recycled in many locations. Recommended ...
