WebMar 12, 2024 · A series of tertiary aliphatic sulfonamides was studied by crystallographic and quantum chemical methods. It was found that the s-character of the nitrogen lone pair is the most important factor defining properties of the S–N bond. WebJul 1, 2014 · Abstract. The potency of Al 3 Zr and Al 3 Nb as grain refiners for Al alloys was investigated from a crystallographic point of view using the edge-to-edge matching (E2EM) model. The results show that both Al 3 Zr and Al 3 3 Zr and Al 3 Nb are potent heterogeneous nucleation refiners for Al grains from the crystallographic point of view.

WebIn fact, until the 1950s, the structure of DNA remained a mystery. In this article, we'll briefly explore how the double-helical structure of DNA was discovered through the work of James Watson, Francis Crick, Rosalind Franklin, and other researchers. Then, we'll take a look at the properties of the double helix itself.
