X-ray Crystallography02:18

X-ray Crystallography

25.8K
The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

Design Example: Setting a Curve Using Design Data

231
Designing and plotting a curve using field data requires precise calculations and execution. A horizontal curve with a radius of 200 meters and an intersection angle of 20 degrees is established using the method of perpendicular offsets from the long chord. The long chord, which spans between the curve's endpoints, is calculated to be 69.46 meters in length. To maintain accuracy in plotting, intervals of 3 meters are selected along the chord.The engineer determines the offset distances for each...

Electronic Structure of Atoms02:28

Electronic Structure of Atoms

28.1K

An atom comprises protons and neutrons, which are contained inside the dense, central core called the nucleus, with electrons present around the nucleus. Taking into account the wave–particle duality of electrons and the uncertainty in position around the nucleus, quantum mechanics provides a more accurate model for the atomic structure. It describes atomic orbitals as the regions around the nucleus where electrons of discrete energy exist, characterized by four quantum...

Radicals: Electronic Structure and Geometry

4.9K
This lesson delves into the geometry of a radical, which is influenced by the electronic structure of the molecule. The principle is similar to that of a lone pair, where the unpaired electron influences the geometry at the radical center.
Accordingly, the structure of a trivalent radical lies between the geometries of carbocations and carbanions. An sp2-hybridized carbocation is trigonal planar, while an sp3-hybridized carbanion is trigonal pyramidal. Here, the difference in geometry is...

Self-Help Support Groups01:28

Self-Help Support Groups

335
Self-help support groups are voluntary, community-based organizations that provide a platform for individuals with shared concerns to exchange support, insights, and practical strategies for coping with life challenges. Typically led by group members or paraprofessionals, these groups form a cornerstone of mental health care, especially in reaching populations that are underserved by traditional healthcare systems.
Accessibility and Cost-Effectiveness
One of the primary strengths of self-help...

Electron Transport Chains01:28

Electron Transport Chains

111.7K
The final stage of cellular respiration is oxidative phosphorylation that consists of two steps: the electron transport chain and chemiosmosis. The electron transport chain is a set of proteins found in the inner mitochondrial membrane in eukaryotic cells. Its primary function is to establish a proton gradient that can be used during chemiosmosis to produce ATP and generate electron carriers, such as NAD+ and FAD, that are used in glycolysis and the citric acid cycle.
The ETC is comprised of...

Area of Science:

  • Crystallography
  • Materials Science
  • Electron Microscopy

Background:

  • 3D electron crystallography (3D-EC) is a powerful technique for determining the structure of submicrometre crystals.
  • A major challenge in 3D-EC is obtaining complete diffraction data due to preferred crystal orientation on conventional flat supports.
  • Preferred orientation leads to systematic data loss (shading), hindering accurate structure determination even with combined datasets.

Purpose of the Study:

  • To introduce novel 3D sample supports designed to mitigate preferred orientation in 3D-EC.
  • To demonstrate the effectiveness of these supports in enabling complete data collection for crystal structure analysis.

Main Methods:

  • Development of two types of 3D sample supports: one with a coiled carbon layer and another with chaotic nylon fibers.
  • Testing the supports using MFI-type zeolites, a crystal type prone to preferred orientation.
  • Utilizing 3D electron crystallography for data collection and analysis.

Main Results:

  • Both novel 3D sample supports successfully disrupt the preferred orientation of crystals.
  • Complete datasets were collected, overcoming the limitations of conventional flat supports.
  • The developed supports are easy to fabricate and offer diverse applications.

Conclusions:

  • The novel 3D sample supports are effective solutions for overcoming preferred orientation in 3D-EC.
  • These supports facilitate complete data collection, crucial for accurate crystal structure determination.
  • The versatility of these 3D supports broadens their applicability in materials science and crystallography.
