The hunt for Scabiosa trenta Hacq: how the pursuit of a phantom ignited a passion for botany and mountaineering

open access: yesNordic Journal of Botany, EarlyView.
Scabiosa trenta Hacq. was first described in 1782 by Balthasar Hacquet, with its specific epithet referring to the Trenta Valley in Slovenia. Since then, S. trenta has been the focus of numerous mountaineering and botanical expeditions, particularly by the alpinist Julius Kugy during the Golden Age of Alpinism, a period in the second half of 19th ...

A Modern Metrical Baseline for Sexing Sheep Horn‐Cores

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Sex determination is essential for reconstructing past livestock management, yet the limited skeletal sexual dimorphism of sheep hinders the identification of ewes, rams, and wethers in archaeological assemblages. Horn‐cores are the most sexually dimorphic element of the sheep skeleton, and here, we establish a new metrical baseline for ...

Development of Cost‐Effective and Highly Transparent Melamine Formaldehyde Resin Modified With Sodium Chloride for Enhancing Glossiness and Abrasion Resistance of Melamine Impregnated Paper

open access: yesPolymer Engineering &Science, EarlyView.
An eco‐friendly melamine‐formaldehyde was produced by the addition of sodium chloride as a modifier. Modified MF resin improved surface gloss and abrasion resistance of decorative paper and decreased the formaldehyde emission. Curing time of the MF resin decreased with the addition of sodium chloride.

Improve the Thermal Conductivity, Insulation Performance and Mechanical Properties of Silicone Rubber by Constructing EG‐PDA‐Cu Hybrid Nanoparticles

open access: yesJournal of Polymer Science, EarlyView.
In this work, a novel expanded graphite‐supported nano‐copper polydopamine composite was designed and synthesized. The procedure involved first modifying EG via a mussel‐inspired technique to deposit a polydopamine coating, after which Cu2+ ions were reduced to immobilize copper nanoparticles onto the EG‐PDA substrate.

From Waste to Value: A Data‐Driven Framework for Sustainable Raw Materials Substitution in the Ceramic Industry

open access: yesSustainable Development, EarlyView.
ABSTRACT With increasing geopolitical risks, environmental pressures, and regulatory demands, the sustainable sourcing of raw materials has become a global priority for achieving the United Nations Sustainable Development Goals (SDGs), particularly SDG 9 (Industry, Innovation and Infrastructure), SDG 12 (Responsible Consumption and Production), and SDG

In Situ Investigation of Microstructure Evolution and Stress Generation During Low‐Pressure Carburizing and Quenching by Means of Synchrotron X‐Ray Diffraction

open access: yessteel research international, EarlyView.
This study uses in situ synchrotron X‐ray diffraction at the German Electron Synchrotron to analyze low‐pressure carburizing (LPC) in steels. The findings reveal surface carbon saturation and carbide formation kinetics, and phase‐specific stress development during quenching. The results show carbide kinetics depend on steel grade and size, while stress
