Tribological characteristics of piston rings in a single-piston hydraulic free-piston engine
, 2017 Purpose A free-piston engine (FPE) is an unconventional engine that abandons the crank system. This paper aims to focus on a numerical simulation for the lubricating characteristics of piston rings in a single-piston hydraulic free-piston engine (HFPE).

Hierarchically Porous Coatings for Cellulose Fibers by Core–Shell Particle Templating
Macromolecular Rapid Communications, EarlyView.Hybrid and functional core–shell particles comprising a silica core and a polymer shell were synthesized and used to develop a coating and etching process applied to a cellulose substrate. This resulted in highly porous, functional coatings on a cellulose membrane for further application in cellulose‐based adsorbers and advanced membrane technology ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Hydraulic manipulators exhibit strong coupling, pronounced nonlinearities, and significant modeling uncertainties, which hinder high‐precision motion control. This paper proposes a finite‐time disturbance observer–based nonlinear robust adaptive control (RAC‐FTDO) framework enhanced by a physically consistent dynamic parameter identification ...

Polymer International, EarlyView.An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Aggregation‐induced enhanced emission for quantification of recycled content in automotive plastics
Polymer International, EarlyView.Quantifying recycled content in four automotive plastics using aggregation‐induced enhanced emission showed that performance was highly dependent on both polymer and additive chemistries. Abstract The use of plastics in the automotive industry is increasing due to their versatility, light weight and affordability.
