The Simplest Piston Problem II: Inelastic Collisions
, 2006 We study the dynamics of three particles in a finite interval, in which two light particles are separated by a heavy ``piston'', with elastic collisions between particles but inelastic collisions between the light particles and the interval ends.

Advanced Materials Technologies, EarlyView.This study demonstrates a cost‐effective hybrid nanofiller approach for developing conductive polyamide 6 filaments via melt spinning. Branched carbon nanotubes combined with carbon black create synergistic networks where spherical CB particles bridge aligned CNTs, maintaining electrical pathways during fiber drawing.

Macroscopic equations for the adiabatic piston [PDF]
, 2007 A simplified version of a classical problem in thermodynamics -- the adiabatic piston -- is discussed in the framework of kinetic theory. We consider the limit of gases whose relaxation time is extremely fast so that the gases contained on the left and ...

Size Effect on Photothermal Heating Ability of Gold Bipyramids
Advanced Optical Materials, EarlyView.Gold bipyramids with identical spectral characteristics exhibits opposite volume‐dependent photo‐thermal heating at single‐particle versus collective scales. The thermal energy can be used to generate mechanical work by powering Stirling engine. Abstract Gold nanoparticles (AuNPs) exhibit photothermal properties that are fundamental to biomedical and ...

P-REx: The Piston Reconstruction Experiment for Infrared Interferometry
, 2017 For sensitive infrared interferometry, it is crucial to control the differential piston evolution between the used telescopes. This is classically done by the use of a fringe tracker.

Tension Pistons: Amplifying Piston Force Using Fluid‐Induced Tension in Flexible Materials
Advanced Functional Materials, 2019 Pistons are ubiquitous devices used for fluid‐mechanical energy conversion. However, despite this ubiquity and centuries of development, the forces and motions produced by conventional rigid pistons are limited by their design.
