This renders the 'HelixJet' as a potential new additive manufacturing tool, in which polyamide powders can be simultaneously surface treated and partially melted to enable plasma鈥恇ased 3D printing of powders usually used in Laser Sintering. Further details can be found in the article by Jan ...
Simple double-helical complexes, so-called helicates, form spontaneously from a penta(bipyridine) ligand and Cu1 ions in solution. Whereas hydrogen bonds and stacking interactions are responsible for holding together the double helix of natural DNA, coordination interactions between Cu鈯 and bipyridine...
Moving one DNA double helix through another by a type II DNA topoisomerase: the story of a simple molecular machine The discovery of the double helix structure of DNA led immediately to questions on the mechanics of unravelling its intertwined strands during replication... ...
Maintaining the quality of interlaced video can be a challenge in video encoding because of the larger spaces between horizontal lines in the same field. While MPEG-1 doesn't support interlaced video at all and MPEG-2 requires entire streams (files) to be either interlaced or progressive, AVC...

A Heckel,PB Dervan 摘要: The cover picture shows a DNA double helix with a pyrrole/imidazole-polyamide bound to the minor groove. The hydrogen bond recognition pattern for the edges of the four Watson-Crick base pairs on the floor of the DNA minor groove is represented as a series of ...

When DNA forms its double-helixstructure, bonds are formed between complementary bases of two chains of nucleotides. The adenine and thymine join together through two hydrogen bonds and guanine and cytosine pair through three hydrogen bonds. It is thought that the fact that the hydroxyl molecule wa...
