In 2015,Gupta, G.; Iqbal, P.; Yin, F.; Liu, J.; Palmer, R. E.; Sharma, S.; Leung, K. Cham-Fai; Mendes, P. M. published 《Pt Diffusion Dynamics for the Formation Cr-Pt Core-Shell Nanoparticles》.Langmuir published the findings.HPLC of Formula: 13534-97-9 The information in the text is summarized as follows:
Layered core-shell bimetallic Cr-Pt nanoparticles were prepared by the formation and later reduction of an intermediate Pt-ion-containing supramol. complex onto preformed Cr nanoparticles. The resultant nanoparticles were characterized by x-ray diffraction anal., TEM, XPS, and aberration-corrected scanning TEM. The results are consistent with the presence of Pt diffusion during or after bimetallic nanoparticle formation, which resulted in a Pt/Cr-alloyed core and shell. The authors postulate that such Pt diffusion occurs by an elec.-field-assisted process according to Cabrera-Mott theory and that it originates from the low work function of the preformed oxygen-defective Cr nanoparticles and the rather large electron affinity of Pt. The experimental process involved the reaction of 6-Bromopyridin-3-amine(cas: 13534-97-9HPLC of Formula: 13534-97-9)
6-Bromopyridin-3-amine(cas: 13534-97-9) belongs to anime. The reaction of alkyl halides, R―X, where X is a halogen, or analogous reagents with ammonia (or amines) is useful with certain compounds. Not all alkyl halides are effective reagents; the reaction is sluggish with secondary alkyl groups and fails with tertiary ones. Its usefulness is largely confined to primary alkyl halides (those having two hydrogen atoms on the reacting site).HPLC of Formula: 13534-97-9
