Influence of the Bonding Electrons on the Scattering of X-Rays by Carbon
@article{Franklin1950InfluenceOT, title={Influence of the Bonding Electrons on the Scattering of X-Rays by Carbon}, author={Rosalind E. Franklin}, journal={Nature}, year={1950}, volume={165}, pages={71-72} }
DURING the course of an investigation of the scattering of X-rays by Various carbons (incompletely graphitized materials containing graphite-like layer-planes but no three-dimensional crystalline order, and showing, therefore, only (00l) crystalline reflexions and (hk) two-dimensional bands) it was observed that the intensity of the (10) band was always anomalously high. The phenomenon was found to be of perfectly general occurrence for a wide variety of carbons. For microcrystalline graphite a…

Grand challenges in cellular biochemistry: the “next-gen” biochemistry
- BiologyFront. Chem.

It is said that Biochemistry is a young scientific discipline, making its “formal” debut toward the end of the 1900th century, with seminal works by Buchner (1897, Jaenicke, 2007), and these early and important contributions marked the road for future work in the fields of chemical and biochemical structures and associated functions.
