This volume presents nine selected chapters discussing recent advances in chemistry research. Chapter One examines the synthesis and various properties of chromophores with aminostyryl quinoxaline moiety for photonic and optoelectronic applications. Chapter Two reviews the importance of the chemiluminescent system of marine chromophore coelenterazine. Chapter Three is a literature review of computational alanine scanning mutagenesis for probing protein stability and protein-protein interactions. Chapter Four is an investigation of various studies of L-alanine in an aqueous medium. Chapter Five reviews the synthesis of indole containing chromophores. Chapter Six reviews the interaction of bis[N-(2,6-dimethylphenyl)aminophenyl-glyoximato-κ2N, N′]nickel(II) dimethyl sulfoxide solvate with some biomolecules by computational chemistry methods. Chapter Seven examines the interaction between DNA bases with the molecular structure of 1,4-Bis[(z)-2-(3-mesityl-3-methylcyclobutyl)-2-(thiosemicarbazono)ethyl]piperazine dimethyl sulfoxide. Chapter Eight reviews the acetoxylation of camphene over activated carbons with sulfonic acid groups. Chapter Nine demonstrates the behavior of short oligomeric molecules as being that of bistable machines.
