Development and Experimental Investigation of a Two-Stroke Opposed-Piston Free-Piston Engine
, 2016 The proposed paper deals with the development process and initial measurement results of an opposed-piston combustion engine for application in a Free-Piston Linear Generator (FPLG). The FPLG, which is being developed at the German Aerospace Center (DLR),

River Research and Applications, EarlyView.ABSTRACT Assessing spatial and temporal variability of clogging in gravel‐bed rivers is challenging because field methods typically rely on labor‐intensive measurements of fine‐sediment content, porosity, or hydraulic conductivity. Clogging is also highly dynamic, driven by hydro‐sedimentary conditions; yet few studies have examined it at large scales ...

Small, EarlyView.An automated MATLAB framework for inverse photoacoustic analysis enables precise thermal characterization of complex multilayer films. Application to electrodeposited CuxSe reveals a stoichiometry‐dependent thermal conductivity governed by lattice anharmonicity, not grain‐size scattering, in these superionic materials. ABSTRACT Precise determination of
