Atomistic Tribology

Nanoscale friction liquid/solid
Atomistic Tribology
Friction Forces Between 2D Materials and Liquids
25.05.2020 TriboNet

2D materials deserved an interest in material science and other disciplines due to their exciting electronic, mechanical, and optical properties. The unique behavior of these materials originate from very strong in-plane atoms interactions and very […]

Atomistic Tribology
High Hardness Boron Rich Boron Carbide is Synthesized using CVD
18.05.2020 TriboNet

Hardness is a material’s resistance to plastic deformation and this property is widely used to rank materials for various engineering applications. Hard materials can be used for cutting, drilling. Hardness frequently correlates with wear resistance […]

Roughness generation
Atomistic Tribology
Atomic scale deformation responsible for surface roughness
04.05.2020 TriboNet

Most of the natural or engineered surfaces are not perfect, meaning they are rough. The surface roughness was found across many scales: from atomic to tectonic. The earth looks smooth from space, but someone standing […]

Lubrication at nanoscale
Atomistic Tribology
Physicists are one step closer to understand lubrication at nanoscale
27.04.2020 TriboNet

The famous picture of transportation of an Egyptian statue to the grave of Tehuti-Hetep, El-Bersheh indicates that the concept of lubrication was already known to ancient Egyptians. The picture below shows how the slaves are […]

Rough and Smooth Particles
Atomistic Tribology
Roughness of the solid particles controls the viscosity of suspension
28.05.2018 TriboNet

The internet is full of videos of people having fun running over white slime. It almost looks as if they were walking on water. But when they stand still, they slowly begin to sink. The […]

Strongest bio-based material
Atomistic Tribology
Bio-based material stronger than steel and spider silk altogether
16.05.2018 TriboNet

Researchers at KTH have produced a bio-based material that is reported to surpass the strength of all known bio-based materials whether fabricated or natural, including wood and spider silk. Working with cellulose nanofibre (CNF), the […]

Friction of a levitated nanoparticle
Atomistic Tribology
Levitated nanoparticles reveal the crucial role of friction in state transitions at nanoscale
25.10.2017 TriboNet

Experiments with levitated nanoparticles reveal role of friction at the nanoscale Transitions occurring in nanoscale systems, such as a chemical reaction or the folding of a protein, are strongly affected by friction and thermal noise. […]

wear simulation
Atomistic Tribology
Researchers simulate wear of materials as they rub together
20.10.2017 TriboNet

Forty years ago, MIT emeritus professor of mechanical engineering Ernest Rabinowicz calculated that 6 percent of the annual U.S. gross domestic product was lost through mechanical wear. His assertion gained enough traction that it became […]

graphene
Atomistic Tribology
Bi-layered materials: graphene – no heat, no friction; h-BN – as strong as diamond.
20.09.2017 TriboNet

A group of researchers from Queen’s University Belfast have discovered a stretchy miracle material that could be used to create highly resistant smart devices and scratch-proof paint for cars. Led by Dr Elton Santos from […]

electrostatic charge
Atomistic Tribology
Triboelectric charges on HDPE are strain induced
08.09.2017 TriboNet

New research indicates how static electricity puts the charge in material, offering answer to centuries-old question For centuries, scientists have tried to understand triboelectric charging, commonly known as static electricity. Triboelectric charging causes toner from […]
