Effect of substrate roughness on the nucleation and growth behaviour of microwave plasma enhanced CVD diamond films – a case study

open access: yesFunctional Diamond, 2023
The influence of substrate surface roughness on the nucleation and growth of diamond films by chemical vapour deposition (CVD) is investigated. Silicon substrates were grinded with six different grit sizes of abrasive papers with a rotating wheel. Si was

Effect of shot peening on surface mechanical properties of selective laser melting TC4 titanium alloy

open access: yesFenmo yejin jishu
Selective laser melting TC4 titanium alloy samples were shot peening with ϕ2.3 mm and ϕ4.0 mm ceramic shots respectively. The surface morphology, surface roughness, surface friction coefficient, surface wear morphology and surface microhardness of the ...

The microbiome in human skin aging

open access: yesFEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Multi-scale analysis of the roughness effect on lubricated rough contact [PDF]

open access: yes, 2014
Determining friction is as equally essential as determining the film thickness in the lubricated contact, and is an important research subject. Indeed, reduction of friction in the automotive industry is important for both the minimization of fuel ...

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer

open access: yesMolecular Oncology, EarlyView.
Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

Effect of the Artificial Bed Roughness’s Shape on Hydraulic Jump’s Characteristics [PDF]

open access: yesعلوم و مهندسی آبیاری, 2018
Hydraulic jumps are the most important type of rapidly variable flow that occur in from the supercritical state to the subcritical state with the sudden increase of the water free surface in a relatively short path, and usually has a high kinetic energy ...

An Axiomatic Approach to the Roughness Measure of Rough Sets [PDF]

open access: yesFundamenta Informaticae, 2011
In Pawlak's rough set theory, a set is approximated by a pair of lower and upper approximations. To measure numerically the roughness of an approximation, Pawlak introduced a quantitative measure of roughness by using the ratio of the cardinalities of the lower and upper approximations.

A new flow chip in combination with multiphoton microscopy as a protocol for longitudinal 3D imaging of tissue calcification under shear stress

open access: yesFEBS Open Bio, EarlyView.
Miniaturized flow chip platform enabling continuous perfusion and longitudinal multiphoton 3D imaging of vascular smooth muscle cell constructs under physiological flow. Brightfield imaging guides region selection, while CellTracker Green and mRuby‐labeled fetuin‐A visualize cells and mineral deposition, respectively. Magnesium supplementation markedly

Protocol for quantifying miRNA trafficking across the endosomal membrane

open access: yesFEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.
