Vergleichende Untersuchung der Eigenschaften recycelter Kohlenstofffasern Comparative investigation of the properties of recycled carbon fibers

Chemie Ingenieur Technik, EarlyView.
Die Akzeptanz recycelter Kohlenstofffasern in der Industrie erfordert eine hohe und standardisierte Faserqualität. In diesem Artikel werden mechanische Eigenschaften sowie die Oberflächenqualität neuer und recycelter Kohlenstofffasern ermittelt und verglichen, um Optimierungspotentiale für das CFK‐Recycling abzuleiten.

Image quality assessment of pediatric chest and abdomen CT by deep learning reconstruction

BMC Medical Imaging, 2021
Background Efforts to reduce the radiation dose have continued steadily, with new reconstruction techniques. Recently, image denoising algorithms using artificial neural networks, termed deep learning reconstruction (DLR), have been applied to CT image ...

Latent Heat Fluxes over Complex Terrain Measured by Airborne Water Vapour and Wind Lidars [PDF]

, 2010
The combination of a water vapour and a wind lidar on an aircraft is an interesting new tool that allows to measure latent heat flux profiles and to portray the small- to mesoscale variability beneath the aircraft trajectory with high accuracy and ...

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.

“I Was Just Like a Sponge, Absorbing All the Wrong Information”: Examining the Role of Social Media in Athletes' Eating Disorder and Recovery Experiences

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Within sport environments, athletes are exposed to norms that circulate narrow meanings about the body and food, contributing to the high prevalence of eating disorders (EDs). While social media can support ED recovery, it can also further constrain food‐ and body‐related messages for athletes.

Comprehensive Analysis of the Degradation Phenomena of Proton Exchange Membrane Water Electrolyzers with Iridium on Antimony Tin Oxide Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study examines the structural and chemical evolution of low‐loaded Ir/ATO anodes during PEM water electrolysis under realistic conditions. Iridium dissolution is largely suppressed. In the early stages, both ionomer and support degradation are detected. Morphological reorganization occurs at the interface between the anode catalyst layer (ACL) and
