Vor 2 Tagen · Rosalind Elsie Franklin (25 July 1920 – 16 April 1958) [1] was a British chemist and X-ray crystallographer whose work was central to the understanding of the molecular structures of DNA (deoxyribonucleic acid), RNA (ribonucleic acid), viruses, coal, and graphite. [2] .
Vor 5 Tagen · This article provides an overview of electron diffraction and electron diffraction patterns, collective referred to by the generic name electron diffraction. This includes aspects of how in a general way electrons can act as waves, and diffract and interact with matter.
Vor 2 Tagen · Far better structural results can be obtained when new approaches of Quantum Crystallography (QCr) utilising aspherical atomic scattering factors are used in the refinement of X-ray data. In short, QCr is crystallography beyond IAM.
Vor 2 Tagen · Methods commonly used to study protein structure and function include immunohistochemistry, site-directed mutagenesis, X-ray crystallography, nuclear magnetic resonance and mass spectrometry. The activities and structures of proteins may be examined in vitro, in vivo, and in silico.
Vor 20 Stunden · Credit: Thomas Shafee/Wikipedia. Scientists have prototyped a new method for "rationally engineering" enzymes to deliver improved performance. They have devised an algorithm, which takes into ...
Vor 2 Tagen · X-Ray Crystallography. Dual-wavelength X-ray generator integrated with image plates and cryogenic systems. The current X-ray generator setup in NII consists of SuperBright rotating anodes (Copper and Chromium) that produce high flux X-rays with two wavelengths (CuKα, 1.54 Å and CrKα, 2.29 Å).
Vor 3 Tagen · This study presents X-ray single-crystal analysis to verify the structure of leading sulfonyl hydrazone 3b, which has proven its potent antimycobacterial activity against Mycobacterium tuberculosis H37Rv with an MIC value of 0.0716 μM, respectively, low cytotoxicity, and very high selectivity indexes (SI = 2216), and which has been ...
