Influence of Temperature on Scratch and Wear Properties of Technical Thermoplastics: Implications for Material Selection

open access: yesAdvanced Engineering Materials, EarlyView.
The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of

Development of Aluminum Scandium Alloys for Hydrogen Storage Valves

open access: yesAdvanced Engineering Materials, EarlyView.
Different aluminum alloy series and various aluminum‐scandium alloys with differing Sc and Zr levels are evaluated for use in hydrogen storage valve production. The alloys undergo hardness testing, optical microscopy, and tensile strength analysis, with hardening behavior studied under varying conditions.

Litter Production in an Area of Amazonian Terra Firme Forest. Part I.Litter - fall, Organic carbon and total Nitrogen Contents of Litter').

open access: yes, 1968
In 1963 anð, L964 litter was collected in a terra firme forest near Manaus, oven-dried and shipped to Europè. The sampleswere subdivided intofour litterfractions (leaves, wood,'fruits, termite fraction), dried at 105o and weighed.

CALPHAD‐Guided Prediction and Interpretation of Phase Formation in Ta–Mo–Cr–Ti–Al Refractory High‐Entropy Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
This study designs Ta–Mo–Cr–Ti–Al refractory high‐entropy alloys with a disordered body‐centered‐cubic A2 crystal structure aiming for improved ductility, lower density, and oxidation resistance. Four alloy compositions are identified by thermodynamic calculations.

Atrazine sensitivity varies among soybean cultivars

open access: yesAgrosystems, Geosciences & Environment
Atrazine carryover from application to a monocot crop may adversely affect soybean (Glycine max (L.) Merr.) grown in rotation. Here, we tested the hypothesis that genotype selection could reduce atrazine carryover damage to soybean.
