[X射线衍射-经典课件]-24:X-Ray Diffraction-宾夕法尼亚大学.pptx,X线(X射线)是一种波长很短的电磁波,波长在~10nm到~0.1nm左右,有很大的穿透能力,能使照相胶片感光,使某些物质发荧光,并能使气体游离。对机体细胞有很强的破坏作用。X线被广泛应用于临床诊断和治疗,
X-Rays Radiographs are the pictures created once X-Rays are passed through a patient and captured on photographic film. The X-Ray process is extremely inefficient as much of the energy is actually lost as heat. X-Rays Wilhelm Rontgen discovered X-Rays on November 8th, 1895 at Wolfsburg Unive...

Until recently, individual protein structure determination using protein X-ray crystallography was often a protracted and resource intensive process, sometimes taking years. To address this, the past decade has seen the emergence of high throughput protein crystallography. Here we seek to review broadly...
