Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 539-74-2, Name is Ethyl 3-bromopropanoate, molecular formula is C5H9BrO2, belongs to bromides-buliding-blocks compound, is a common compound. In a patnet, author is Karuppiah, Sujatha, once mentioned the new application about 539-74-2, SDS of cas: 539-74-2.
Influence of surfactants on structural, morphological, optical and antibacterial properties of SnO2 nanoparticles
Tin oxide (SnO2) nanoparticles were synthesised using various surfactants of different charges (n-cetyl trimethyl ammonium bromide, sodium dodecyl sulphate and TRITON X-100) by the co-precipitation method. The synthesised nanomaterials were characterised using different techniques to study their structural, surface morphological, optical and anti-bacterial activities. X-ray diffraction patterns revealed the formation of a tetragonal rutile structure in pure and surfactants-aided SnO2 nanoparticles and the results show good agreement with JCPDS data [41-1445]. The crystallite size of SnO2 nanoparticles was found to decrease with the addition of surfactants. Scanning electron microscopy images exhibit spherical shape morphology with an average diameter of 30-75 nm for pure and surfactants-aided SnO2 nanoparticles. The band gap energy of the prepared materials was estimated from the UV-visible absorption spectra and a considerable increase in band gap energy was observed in surfactants-aided SnO2 nanoparticles (3.487, 3.57, 3.50 and 3.3 eV). The antibacterial activities of the synthesised nanoparticles were studied against Escherichia coli and Staphylococcus aureus bacteria.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 539-74-2. The above is the message from the blog manager. SDS of cas: 539-74-2.
