We have measured the helical parameters of DNA in concentrated solutions by x-ray fiber diffraction methods. Fibers of the sodium salt of DNA were swollen with water within capillaries; the capillary ...

Since the discovery of the diffraction of X-rays by crystals just over 100 years ago, X-ray diffraction as a method of structure determination has dominated structural research in materials science ...

The collective response of charged particles to intense fields is intrinsic to plasma accelerators and radiation sources, relativistic optics and many astrophysical phenomena. Here we show that a ...

Double helical covalent polymers—which are spiraling collections of nature’s building blocks—are fundamental to life itself, and yet, despite decades of research, scientists have never been able to ...

A discovery by University of Strathclyde researchers could have a major impact on advancing smaller, cheaper, laser-driven particle accelerators - and their potential applications. The research found ...

Description: (EAS 511) Analysis of two- and three-dimensionally ordered structures by optical, electron, and X-ray diffraction methods. Geometry of diffraction. Detection of diffraction. Intensity of ...

Dr Franklin used X-rays to study the structure of DNA and found that it existed in at least two different forms – DNA-A, which occurs when the molecule is dehydrated, and DNA-B, the hydrated structure ...
