Pentalenene formation mechanisms redux
Org. Biomol. Chem., 2014Quantum chemical calculations are used to assess various means of lowering the barrier for the dyotropic rearrangement previously proposed to occur during the carbocation rearrangement process promoted by pentalenene synthase. Several means of lowering this barrier, including a stepwise pathway for dyotropic rearrangement, are uncovered.

Surface texture formation mechanism based on the ultrasonic vibration-assisted grinding process
, 2020It is widely accepted that surface textures can significantly improve the tribological properties of surfaces. The purpose of this research was to study surface texture formation mechanism through the ultrasonic vibration-assisted grinding process. First,

Mechanisms of procentriole formation
Trends in Cell Biology, 2008The centrosome comprises a pair of centrioles and associated pericentriolar material, and it is the principal microtubule-organizing centre of most animal cells. Like the genetic material, the centrosome is duplicated once and only once during the cell cycle. Despite the fact that both doubling events are crucial for genome integrity, the understanding

Chitosan-alginate films were prepared through layer-by-layer assembly combined with ferulic acid crosslinking. Their mechanical properties, opacity, and hydrophobicity were compared to films prepared by direct mixing, crosslinking alone, and LBL assembly

Mechanism of plastein formation
Biochimica et Biophysica Acta, 1959Abstract The formation by chymotypsin of plastein from concentration peptic hydrolyzates of egg albumin has been investigated in detail. Some properties of plastein are described. Free [14C]amino acids are not incorporated into plastein to an appreciable degree.

Angewandte Chemie
Carbon dots (CDs), as a kind of zero-dimensional nanomaterials, have been widely synthesized by bottom-up methods from various precursors. However, the formation mechanism is still unclear and controversial, which also brings difficulty to the regulation

Mechanisms of Thrombus Formation
New England Journal of Medicine, 2008This review is an account of recent advances in our understanding of the mechanisms of thrombus formation, with emphasis on two independent pathways: one involving primarily platelets and the other initiated by tissue factor.

Urologic Clinics of North America, 1997
This article reviews the physical principles involved in urolithiasis. For urinary stones to form, crystals must form first and they then should be retained in the urinary tract. These phenomena require the interaction between the forces of saturation, crystal inhibition, crystal nucleation, growth aggregation, and retention, which all occur in a ...

Mechanisms of Blister Formation
Archives of Dermatology, 1957Blister or vesicle formation in human skin has no doubt been a recognized entity since man began, or at least since his first contact with fire. In view of this fact and the fact that there are more than 30 quite distinct dermatoses associated with blister formation, it is strange that so little is known about the actual mechanisms of blister formation.
