Summary
This study addresses claims about spin-coated films, refuting the idea that background x-ray intensity indicates randomly oriented grains. Evidence suggests the films are not randomly oriented, contrary to previous assertions.
Area of Science:
- Materials Science
- Crystallography
Background:
- A previous study by Lu and Tang questioned the epitaxial nature of spin-coated films.
- They attributed background intensity in x-ray pole figures to randomly oriented grains.
Purpose of the Study:
- To refute the claim that spin-coated films lack epitaxial quality.
- To provide evidence against the interpretation of background intensity as randomly oriented grains.
Main Methods:
- Analysis of 2θ x-ray diffraction patterns.
- Examination of x-ray pole figures for spin-coated films.
- Comparison of background intensity with single-crystal substrates.
Main Results:
- No evidence of randomly oriented grains was found in the 2θ x-ray patterns.
- The background intensity in pole figures was comparable to that of single-crystal substrates.
- This finding contradicts the assumption of randomly oriented grains.
Conclusions:
- The interpretation of background intensity in x-ray pole figures by Lu and Tang is inconsistent with our data.
- The spin-coated films exhibit characteristics that do not support the claim of being non-epitaxial due to random grain orientation.

01:35Asymmetric Lipid Bilayer
Biological membranes show uneven distribution of different types of lipids in the inner and outer layers, resulting in transverse asymmetric membranes. The treatment of the erythrocyte membrane with the enzyme phospholipase confirmed the asymmetric nature of the lipid bilayer. The enzyme hydrolyzes lipids into fatty acids and hydrophilic groups. The phospholipase acts only on the outer layer of the membrane, while the inner layer remains intact. The phospholipase treatment resulted in 80%...
01:18Detergent Purification of Membrane Proteins
Detergents are used to purify the integral proteins of the membrane. The hydrophobic portion of the detergent can replace membrane phospholipids while solubilizing the membrane proteins. When detergent monomers reach a specific concentration in a solution called critical micelle concentration (CMC), they form micelles. Above CMC, the concentration of the detergent monomers remains in equilibrium with the micelle. The number of detergent monomers present in the CMC varies for each detergent, and...
00:59COP Coated Vesicles
Membrane-enclosed structures called vesicles transport proteins and lipids across the cell. The vesicles derive their cargo from the plasma membrane, Golgi, ER, or endosome. Coated vesicles are spherical, protein-coated carriers with a 50–100 nm diameter that mediate bidirectional transport between the ER and the Golgi. The distribution of proteins between the ER and Golgi complex is dynamic and is maintained by different coated vesicles. Their formation is driven by the assembly of different...
01:32Pinching-off of Coated Vesicles
Vesicle budding is orchestrated by distinct cytosolic proteins such as adaptor proteins, coat proteins, and GTPases. To initiate vesicle budding, membrane-bending proteins containing crescent-shaped BAR domains bind to the lipid heads in the bilayer and distort the membrane to form a protein-coated vesicle bud. Adaptors proteins such as AP2 for clathrin-coated vesicles can nucleate on the deformed membrane. Finally, coat proteins such as clathrin or COPI and COPII assemble into a coat forming...
01:16Cell Motility through Blebbing
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.

01:13Cell-matrix's Response to Mechanical Forces
In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue.
