The mechanisms and applications of friction energy dissipation

open access: yesFriction, 2022
About 30% of the world’s primary energy consumption is in friction. The economic losses caused by friction energy dissipation and wear account for about 2%–7% of its gross domestic product (GDP) for different countries every year.

A Mechanism of Energy Dissipation in Cyanobacteria [PDF]

open access: yesBiophysical Journal, 2009
When grown under a variety of stress conditions, cyanobacteria express the isiA gene, which encodes the IsiA pigment-protein complex. Overexpression of the isiA gene under iron-depletion stress conditions leads to the formation of large IsiA aggregates ...

Emergent energy dissipation in quantum limit

open access: yesScience Bulletin
Energy dissipation is of fundamental interest and crucial importance in quantum systems. However, whether energy dissipation can emerge inside topological systems remains a question, especially when charge transport is topologically protected and quantized.

Calibration of an elastoplastic model of sand liquefaction using the swarm intelligence with a multi-objective function

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
According to post-seismic observations, spectacular examples of engineering failures can be ascribed to the occurrence of sand liquefaction, where a sandy soil stratum could undergo a transient loss of shear strength and even behave as a “liquid ...
