Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The article delves into the structural deformation of polymer additives in oil under high shear flow, a critical aspect for improving the performance of lubricants in automotive and machinery applications. It discusses the significance of polymer additives in reducing friction and wear, and their impact on viscosity and fuel economy. The study employs Small-Angle X-ray Scattering (SAXS) to visualize the deformation of polymer chains under high shear, revealing that higher molecular weight polymers exhibit greater deformation. The research also investigates the correlation between polymer deformation and viscosity, providing insights into the optimization of polymer additives for enhanced lubricant performance. The experimental data and theoretical models presented in the article offer valuable insights into the behavior of polymer additives under high shear conditions, contributing to the development of more efficient lubricants.
