Viscoelastic Properties of Cells: Modeling and Identification by Atomic Force Microscopy
(Journal article; Peer reviewed, 2017)Identification of mechanical properties of cells has previously been shown to have a great potential and effectiveness on medical diagnosis. As a result, it has gathered increasing interest of researchers over the recent ... -
Viscoelastic properties of interfacial lignosulfonate films and the effect of added electrolytes
(Peer reviewed; Journal article, 2020)New evidence is presented, which confirmed interfacial gelling of lignosulfonates in presence of di- and trivalent cations. In this article, the viscoelastic properties of lignosulfonate films at the water-xylene interface ... -

Viscoelastic properties of nanocellulose based inks for 3D printing and mechanical properties of CNF/alginate biocomposite gels
(Journal article; Peer reviewed, 2019)Inks for 3D printing based on cellulose nanofibrils (CNFs) or mixtures of CNFs and either cellulose nanocrystals (CNCs) or alginate were assessed by determining their viscoelastic properties i.e. complex viscosity and ... -
Viscosity in modified gravity
(Journal article; Peer reviewed, 2012)A bulk viscosity is introduced in the formalism of modified gravity. It is shown that, based on a natural scaling law for the viscosity, a simple solution can be found for quantities such as the Hubble parameter and the ... -
Viscosity measurements of CO<inf>2</inf>-rich; CO<inf>2</inf> + N<inf>2</inf> and CO<inf>2</inf> + H<inf>2</inf> mixtures in gas or supercritical phase at temperatures between 273 and 473 K and pressures up to 8.7 MPa
(Peer reviewed; Journal article, 2022)New experimental viscosity data of three binary CO2-rich mixtures with approximate mole fractions of 0.93 CO2 + 0.07 H2, 0.80 CO2 + 0.20 H2, and 0.90 CO2 + 0.10 N2 are reported. The measurements were performed at four ... -
Viscosity, Density and Volatility of Binary Mixtures of Imidazole, 2-Methylimidazole, 2,4,5-Trimethylimidazole and 1,2,4,5-Tetramethylimidazole with Water
(Journal article; Peer reviewed, 2019)Experimental measurements and modeling of the density and viscosity of binary solutions of imidazole, 2-methylimidazole, 2,4,5-trimethylimidazole, and 1,2,4,5-tetramethylimidazole with water have been conducted. The ... -
Viscosity-Induced Crossing of the Phantom Barrier
(Journal article; Peer reviewed, 2015)We show explicitly, by using astrophysical data plus reasonable assumptions for the bulk viscosity in the cosmic fluid, how the magnitude of this viscosity may be high enough to drive the fluid from its position in the ... -
Viscosity-induced crossing of the phantom divide in the dark cosmic fluid
(Journal article; Peer reviewed, 2013-12-10)Choosing various natural forms for the equation-of-state parameter w and the bulk viscosity ζ, we discuss how it is possible for a dark energy fluid to slide from the quintessence region across the divide w = −1 into the ... -
Viscous Cosmology for Early- and Late-Time Universe
(Journal article; Peer reviewed, 2017)From a hydrodynamicist’s point of view the inclusion of viscosity concepts in the macroscopic theory of the cosmic fluid would appear most natural, as an ideal fluid is after all an abstraction (exluding special cases such ... -
Viscous coupled fluids in terms of a log-corrected equation-of-state
(Peer reviewed; Journal article, 2021)In this paper, we consider a class of cosmological fluids that possess properties analogous to those of crystalline solids undergoing isotropic deformations. Our research is based on a modified log-corrected power-law ... -
Viscous regularization for cohesive zone modelling under constant displacement: an application to hydrogen embrittlement simulation
(Journal article; Peer reviewed, 2016)The convergence problem during the cohesive zone modelling of hydrogen embrittlement in constant displacement scenario is attributed to the numerical instability which is studied analytically in the present work. The ... -
Visibilidades de crianças da infância
(Peer reviewed; Journal article, 2014)This article discusses the different meanings of ‘child’, ‘children’ or ‘childhood’ within different contexts, in order to analyze the relevance of what may be called visibility – or invisibility – of childhood. For the ... -
Visible light-exposed lignin facilitates cellulose solubilization by lytic polysaccharide monooxygenases
(Peer reviewed; Journal article, 2023)Lytic polysaccharide monooxygenases (LPMOs) catalyze oxidative cleavage of crystalline polysaccharides such as cellulose and are crucial for the conversion of plant biomass in Nature and in industrial applications. Sunlight ... -
Visible-Light-Driven Photochromism of Hexagonal Sodium Tungsten Bronze Nanorods
(Journal article; Peer reviewed, 2013)Single-crystalline sodium tungsten bronze (Na-WO3) nanorods with typical diameters of 10–200 nm and lengths of several micrometers were prepared via hydrothermal synthesis. The as-prepared Na-WO3 nanorods crystallized in ... -
Vision Based Localization for Subsea Intervention
(Chapter; Peer reviewed, 2017)A vision based underwater localization system using fiducial markers is proposed. The system is implemented as a new control mode in a shared control system for ROVs and tested experimentally in a pool. A high accuracy ... -
A vision for safer food contact materials: Public health concerns as drivers for improved testing
(Peer reviewed; Journal article, 2023)Food contact materials (FCMs) and food contact articles are ubiquitous in today’s globalized food system. Chemicals migrate from FCMs into foodstuffs, so called food contact chemicals (FCCs), but current regulatory ... -
Vision Restricted Path Planning and Control for Underactuated Vehicles
