What is the link between a grain silo, a nylon sleeping bag and a flying helicopter? They can all accumulate triboelectric charges! The charges accumulate because the materials in relative motion are insulating materials (respectively […]

Grease definition The word grease is derived from an old French word “Graisse” meaning thick or fat. A grease is a solid to semi-solid product of suspension of thickener into a liquid lubricant. Grease composition […]

Lubrication between two surfaces depends on their respective co-efficient of frictions, surface finishes and also the type of lubricant used, if there is any. It is known that the temperature at which these surfaces  are […]

It all started with a shaky washing machine. Pedro Reis, head of the Flexible Structures Laboratory at EPFL’s School of Engineering, rolled up a piece of fabric and placed it under the machine to stop […]

Electric vehicle technology has been considered as one of the most important upcoming technologies in the present world. There is most definitely a crucial reason for this consideration and this is not solely relying on […]

  Tribology is a term used to define combination of friction, wear and lubrication. Tribology has been used in various fields to improve reliability and longevity of systems. Sports engineering applies engineering disciplines like mathematics, […]

As humans, we interact with the environment via our senses (sight, hearing, smell, taste, and touch). Touch perception has been in the attention of scientist for decades, with applications in the textile, robotics, or sports […]

Electric vehicles are arguably one of the most important inventions of our times. Aiming to lower carbon emissions and to reduce additional harmful effects on our environment, these machines are designed with innovation and precision […]
