Modeling of joints for the dynamic analysis of truss structures [PDF]
An experimentally-based method for determining the stiffness and damping of truss joints is described. The analytical models use springs and both viscous and friction dampers to simulate joint load-deflection behavior.

Repeating Nuclear Transients From Repeating Partial Tidal Disruption Events
Astronomische Nachrichten, EarlyView.ABSTRACT Extragalactic nuclear transients that exhibit repeating outbursts can be modeled as the repeated dynamical interaction between bound stars and supermassive black holes (SMBHs). A subset of these transients, with recurrence timescales of months‐to‐years, have been explained as accretion flares from the repeated tidal stripping of a star by an ...

Batteries &Supercaps, EarlyView.On a digitized laboratory extruder, discrete element method modelling is studied, considering two classes of particles representing aggregates of 1) active material and 2) binder and carbon material is studied. Various extrusion scenarios leading to the formation of filaments devoted to the 3D printing of lithium‐ion battery electrodes are studied. The

Chemistry – A European Journal, EarlyView.Glycerol ethoxylate (GEO), a branched ethylene glycol derivative, both toughens commercial PLLA and accelerates its chemical recycling to L‐lactide. The lead sample, containing 10 wt.% GEO, shows 9x higher elongation at break and 6x higher tensile toughness than pure PLLA. The GEO–PLLA samples are efficiently chemically recycled to L‐lactide, even when

The Filament Extension Atomization Process for Powder Production of Elastic Fluids
Chemie Ingenieur Technik, EarlyView.Filament extension atomization is a promising technique for spraying a wide range of materials, enabling narrow droplet size distributions. This study examines the behavior of various fluids and suspensions to define application limits and identify optimal operating conditions.

Structurally adaptive space crane concept for assembling space systems on orbit [PDF]
Many future human space exploration missions will probably require large vehicles that must be assembled on orbit. Thus, a device that can move, position, and assemble large and massive spacecraft components on orbit becomes essential for these missions.

Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit
Contributions to Plasma Physics, EarlyView.ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.
