REOB/SBS Composite-Modified Bitumen Preparation and Modification Mechanism Analysis

Buildings, 2023
To investigate the effect of recycled engine oil bottoms (REOB) as a compatibilizer on the properties of styrene–butadiene–styrene-modified bitumen (SBS-PMB), this paper studied the preparation method, properties, and micro-mechanism of composite ...

Fading mechanism on grain refinement and modification with Al-B-Sr master alloys in an aluminium-silicon cast alloy [PDF]

Archives of Metallurgy and Materials, 2022
A fading mechanism during casting of treated Al-B-Sr master alloys in an aluminium-silicon cast alloy was investigated. Two different master alloys, the Al-3%B-3%Sr and Al-4%B-1%Sr were demonstrated for the efficiency test both grain refinement and ...

Protein Modification at Tyrosine with Iminoxyl Radicals

, 2021
Post-translational modifications (PTMs) of proteins are a biological mechanism for reversibly controlling protein function. Synthetic protein modifications (SPMs) at specific canonical amino acids can mimic PTMs.

Preparation and Super-Hydrophobic Mechanism Analysis of FAS-17-Modified SiO2/PDMS Coatings for High-Voltage Composite Insulators

, 2023
Pollution flashover on insulators is one of the greatest challenges affecting the smooth operation of high-voltage transmission lines. Demonstrating super-hydrophobic coatings on insulators’ interfaces is an effective measure to prevent insulator ...

Helicobacter pylori-induced histone modification, associated gene expression in gastric epithelial cells, and its implication in pathogenesis. [PDF]

, 2010
Histone modifications are critical in regulating gene expression, cell cycle, cell proliferation, and development. Relatively few studies have investigated whether Helicobacter pylori, the major cause of human gastric diseases, affects histone ...

Preparation of nanocrystal modificator and its modification mechanism

Transactions of Nonferrous Metals Society of China, 2007
Abstract In order to increase the modifying effect, the Cu-P master alloy was rapidly solidified with melt-spin method, and the nano-sized ribbon was gained at 105–106 °C/s. Subsequently, ZL109 alloy was modified by nanocrystal and massive Cu-P master alloy, respectively, with molten metal casting method.

Predicting the mechanism of phospholipidosis

, 2012
The mechanism of phospholipidosis is still not well understood. Numerous different mechanisms have been proposed, varying from direct inhibition of the breakdown of phospholipids to the binding of a drug compound to the phospholipid, preventing breakdown.

Transglycosylation: A mechanism for RNA modification (and editing?) [PDF]

Bioorganic Chemistry, 2005
The vast majority of the ca. 100 chemically distinct modified nucleosides in RNA appear to arise via the chemical transformation of a genetically encoded nucleoside. Two notable exceptions are queuosine and pseudouridine, which are incorporated into tRNA via transglycosylation.

Mechanisms of Modificational Variability

Ecological genetics, 2007
Types of modifications and their position within the traditional classification of variability are analyzed. Through this approach contradictory status of the classification based upon phenomenology of variability is demonstrated. Interdependency of modifications and of inherent variability permits to pose an alternative classification of variability ...
