Surface tension of steel at high temperatures

open access: yesSN Applied Sciences, 2023
Surface tension is a material property that is needed to describe fluid behaviour, which impacts industrial processes, in which molten material is created, such as thermal cutting, welding and Additive Manufacturing.

Surface energy and surface tension of liquid metal nanodrops

open access: yesEPJ Web of Conferences, 2011
A unitary approach has been proposed for the calculation of surface energy and surface tension of nanoparticle being in equilibrium with its saturated vapor on both flat and curved surfaces at given temperature.

Surface tension implementation for Gensmac 2D [PDF]

open access: yes, 2001
In the present work we describe a method which allows the incorporation of surface tension into the GENSMAC2D code. This is achieved on two scales. First on the scale of a cell, the surface tension effects are incorporated into the free surface boundary ...

Softening of edges of solids by surface tension [PDF]

open access: yes, 2014
Surface tension tends to minimize the area of interfaces between pieces of matter in different thermodynamic phases, be they in the solid or the liquid state. This can be relevant for the macroscopic shape of very soft solids, and lead to a roughening of

The relationship between the surface tension and the saturated vapor pressure of model nanofluids

open access: yesHolodilʹnaâ Tehnika i Tehnologiâ, 2019
Information on surface tension is necessary for modeling boiling processes in nanofluids. It was shown that the problem of predicting the surface tension of complex thermodynamic systems, such as nanofluids, remains outstanding.

The Origin of Surface Tension

open access: yesInterPore Journal
In passing from the molecular description of matter to the continuum scale, many material properties and physical quantities emerge that do not exist at the molecular scale. They account for the way we observe lumped effects of molecular properties. So,

Surface tension of nanoparticle dispersions unravelled by size-dependent non-occupied sites free energy versus adsorption kinetics

open access: yesnpj Microgravity, 2022
The surface tension of dispersions presents many types of behaviours. Although some models, based on classical surface thermodynamics, allow partial interpretation, fundamental understanding is still lacking.

Influence of Surface Tension on Dynamic Characteristics of Single Bubble in Free-Field Exposed to Ultrasound

open access: yesMicromachines, 2022
The motion of bubbles in an ultrasonic field is a fundamental physical mechanism in most applications of acoustic cavitation. In these applications, surface-active solutes, which could lower the surface tension of the liquid, are always utilized to ...

Surface tension of surface-modified silica nanoparticles’ dispersions: The effect of temperature

open access: yesResults in Surfaces and Interfaces
This study examined the effect of temperature on the surface activity of surface-modified silica nanoparticles’ dispersions. Silica nanoparticles were functionalized with hydrophobic n-propyl, n-hexyl, or n-octyl groups, as well as hydrophilic methoxy ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.
