X ray crystallography basics explained - This lecture explains about the X ray crystallography technique to understand the protein structure. X-ray Crystallography is a scientific method used to determine the arrangement of atoms of a crystalline solid in three dimensional space. This technique takes advantage of the interatomic spacing of most crystalline solids by employing them as a diffraction gradient for x-ray light. This video lecture describes the principles of x ray crystallography and the mechanisms of x ray diffraction studies that gives arise to the crystallographic structure of unknown protein samples.

Powder X-Ray Diffraction (1 out of 2)
 
04:42
Powder X-Ray Diffraction (XRD) allows the determination of crystallographic density and hence crystal structure of unknown crystalline solids. X-rays are diffracted by atoms in a plane and a spherical wave is radiated. If there are two or more such scattering centres, the spherical waves at specific angles reinforce one another (constructive interference) and at other angles cancel one another (destructive interference). A crystal with planes oriented at an angle θ to an incident x-ray beam of wavelength λ will diffract the rays according to Bragg's equation: 2dsinθ = nλ. In video (1 out of 2), the concept of XRD will be illustrated for compound Tungsten which has a BCC structure using planes 110 and 200. In video (2 out of 2), with the Bragg’s angle θ obtained from the Powder XRD Spectrum, the unit cell length and volume and hence the experimental crystallographic density (g/cm3) is calculated. Interplanar distance is also determined. Other molecular animation videos available at http://www.chemistry.nus.edu.sg/educa... - Video Gallery or via the "Animol" app on iOS and Android.

X ray Diffraction
 
08:53
Useful for CBSE, ICSE, NCERT & International Students Grade 12 Subject: Chemistry Lesson : Solid State Topic: X-ray Diffraction X-ray diffraction (XRD) is a powerful nondestructive technique for characterizing crystalline materials. It provides information on structures, phases, preferred crystal orientations (texture), and other structural parameters, such as average grain size, crystallinity, strain, and crystal defects. X-ray diffraction peaks are X-ray Diffraction (XRD) and X-ray Reflectivity (XRR) techniques from Evans Analytical Group (EAG).produced by constructive interference of a monochromatic beam of x-rays scattered at specific angles from each set of lattice planes in a sample. The peak intensities are determined by the distribution of atoms within the lattice. Consequently, the x-ray diffraction pattern is the fingerprint of periodic atomic arrangements in a given material. A search of the ICDD standard database of x-ray diffraction patterns enables quick phase identification for a large variety of crystalline samples.

This resource is a video guide, which shows how to obtain a diffraction pattern of a powder with the help of X-Ray diffractometer. The video covers a sample praparation, sample placement, and the measurement of 2theta angles of diffracted by the sample X-rays. X-ray diffraction is a non-destructive analytical characterisation technique employed to identify crystalline phases which may be present in the sample. It also determines structural properties, such as defects, epitaxy, grain size, phase composition and preferred orientation.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ A diffractometer is a measuring instrument for analyzing the structure of a material from the scattering pattern produced when a beam of radiation or particles (such as X-rays or neutrons) interacts with it. Because it is relatively easy to use electrons or neutrons having wavelengths smaller than a nanometer, electrons and neutrons may be used to study crystal structure in a manner very similar to X-ray diffraction. Electrons do not penetrate as deeply into matter as X-rays, hence electron diffraction reveals structure near the surface; neutrons do penetrate easily and have an advantage that they possess an intrinsic magnetic moment that causes them to interact differently with atoms having different alignments of their magnetic moments. A typical diffractometer consists of a source of radiation, a monochromator to choose the wavelength, slits to adjust the shape of the beam, a sample and a detector. In a more complicated apparatus, a goniometer can also be used for fine adjustment of the sample and the detector positions. When an area detector is used to monitor the diffracted radiation, a beamstop is usually needed to stop the intense primary beam that has not been diffracted by the sample, otherwise the detector might be damaged. Usually the beamstop can be completely impenetrable to the X-rays or it may be semitransparent. The use of a semitransparent beamstop allows the possibility to determine how much the sample absorbs the radiation using the intensity observed through the beamstop. There are several types of X-ray diffractometer, depending of the research field (material sciences, powder diffraction, life sciences, structural biology, etc.) and the experimental environment, if it is a laboratory with its home X-ray source or a Synchrotron. In laboratory, diffractometers are usually a "all in one" equipment, including the diffractometer, the video microscope and the X-ray source. Plenty of companies manufacture "all in one" equipment for X-ray home laboratory, such as Bruker, Rigaku, PANalytical, Thermo Fisher Scientific and many others. There are fewer diffractometer manufacturers for synchrotron, owing to few numbers of x-ray beamlines to equip and the need of solid expertise of the manufacturer. For material sciences, Huber diffractometers are widely known and, for structural biology, Arinax diffractometers are the reference. Nonetheless, due to few numbers of manufacturers, a large amount of synchrotron diffractometers are "Homemade" diffractometers, realized by synchrotron engineers team.
