Taxonomy for the assessment of the subjective experience of curly hair manageability

open access: yesInternational Journal of Cosmetic Science, Volume 46, Issue 6, Page 1074-1087, December 2024.
An instrument for assessing subjectively curly hair manageability was designed and validated. The instrument is based on a taxonomy of hair goals, haircare perceptions and preferred practices, and on the degree of hair curvature. It can support the design and testing of products for hair with high curvature as well as the development of applications ...

Synthesis and Characterization of Molybdenum Disulfide Nanoflowers and Nanosheets: Nanotribology

open access: yesJournal of Nanomaterials, Volume 2015, Issue 1, 2015., 2015
This paper reports the solvothermal synthesis of MoS2 nanoflowers and nanosheets. The nanoflowers have a mean diameter of about 100 nm and were obtained using thioacetamide (C2H5NS) as a sulfur source. The few layered nanosheets were obtained using thiourea (CH4N2S) as a sulfur source.

Rethinking Models of DNA Organization in Micrometer‐Sized Chromosomes from the Perspective of the Nanoproperties of Chromatin Favoring a Multilayer Structure

open access: yesSmall Structures, Volume 5, Issue 10, October 2024.
The relationship between the self‐associative properties of nucleosomes at the nanoscale and the micrometric structure of chromosomes is highlighted in this perspective. The multilayer chromosome model, in which the stacked structure is maintained by weak face‐to‐face interactions between nucleosomes in adjacent layers, is compatible with all the ...

Nanotribology and its Need-A Review [PDF]

open access: yesInternational Journal of Trend in Scientific Research and Development, 2019
tribology is a texture of two latin words tribo and lodgy . Tribo refers adding glove and lazy data. The Greeks first added it to appreciate the development of huge stones on the surface of the world. Today Tribology accepts a fundamental job in different imaginative districts in advanced mechanical organizations of semiconductor and data emissions ...

Interlayer Friction and Adhesion Effects in Penta‐PdSe2‐Based van der Waals Heterostructures

open access: yesAdvanced Science, Volume 11, Issue 34, September 11, 2024.
The greater the difference in ionicity between the two 2D materials comprising the sliding interfaces is, the lower the interlayer friction, providing key criteria for designing ultralow friction 2D material friction pairs. Abstract Due to their inherent lattice mismatch characteristics, 2D heterostructure interfaces are considered ideal for achieving ...

Effect of normal load and roughness on the nanoscale friction coefficient in the elastic and plastic contact regime

open access: yesBeilstein Journal of Nanotechnology, 2013
The influence of applied normal load and roughness on the tribological behavior between the indenter and sample surface during nanoindentation-based scratching has been experimentally investigated by using different surfaces (fused silica and diamond ...

Nonmonotonic load‐dependence of friction during nanoparticle manipulation

open access: yesMicro &Nano Letters, Volume 19, Issue 4, July 2024.
The friction, wear and energy loss between two contact interfaces strongly depend on the motion state (sliding or rolling) of nanoparticles (NPs) when applied as nano‐additive in the fields of lubrication or ultra‐precision manufacturing. Here, the tests to manipulate single SiO2 nanoparticle (NP) on silicon surface using a nanoscale probe detected the

On nanotribology modeling [PDF]

open access: yesComputational Continuum Mechanics, 2008
Предложена новая модель трения на наноуровне, представляющая собой обобщение классических моделей Томлинсона и Френкеля–Конторовой на случай учета дальнодействия в рамках теории центральных парных взаимодействий. Построены численные решения задач об определении сил трения, распределений сил и перемещений в деформируемой цепочке для разных моделей ...
