Slip versus dilation tendency parameter space as a tool for prospecting structurally controlled geothermal systems in greenfield: insights from the greater Ruhr region

Deep Underground Science and Engineering, EarlyView.
This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Corrosion Behavior of Commercial FeCrAl and TiAl Alloys in Molten Pb With 2E‐7 wt% Oxygen at 600°C and 700°C

Materials and Corrosion, EarlyView.
Excellent corrosion resistance of commercial Al‐containing materials is shown for exposures to liquid lead (Pb) at 600°C. However, oxide scale failure occurs at 700°C. The formed oxide scales and their failure mechanisms are explored. ABSTRACT Liquid lead (Pb) is an attractive heat transfer fluid for advanced thermal energy storage (TES) systems.

Environmental and socio‐economic factors behind data provision in 17 citizen science projects

People and Nature, EarlyView.
Abstract Citizen science approaches in ecology have recently become increasingly popular. Although many advantages, such as the cost‐effective collection of vast amounts of data, outweigh the disadvantages, most projects face difficulties, such as non‐random sampling, pseudo‐absences or various biases, such as detection/reporting biases or participant ...

Urinary Collagen Peptides Predict Mortality

PROTEOMICS, EarlyView.
ABSTRACT Organ fibrosis caused by the presence of excessive extracellular matrix (ECM) is related to mortality. Urinary peptide signatures were reported to be predictive of death in SARS‐CoV‐2 and chronic kidney disease. Such signatures were composed for 68% of collagen fragments.

Enhancing Tea Agrifood System Resilience Amid Geopolitical Tensions: A Resource Nexus‐Based System Dynamics Analysis

Sustainable Development, EarlyView.
ABSTRACT Geopolitical conflicts are increasingly threatening global food security, economic stability, and peace, impacting Tanzania's tea agrifood system. This study develops a quantitative Resource Nexus‐based system dynamics simulation model assessing the feedbacks and interdependencies among key environmental and socioeconomic resources shaping ...

In Situ Alloying of H13 Tool Steel With TiC via PBF‐LB/M

steel research international, EarlyView.
H13 tool steel is in situ alloyed with titanium carbides (TiC) in amounts up to 30 wt.%. This approach offers the advantage that the carbides melt only partially during processing, preventing excessive carbon enrichment of the steel matrix. The resulting microstructure consists of coarse, undissolved and fine, reprecipitated carbides, leading to grain ...

Tailored Hardening and Isothermal Bainitizing of Additively Manufactured Nitrogen‐Enhanced Martensitic Chromium Steel

steel research international, EarlyView.
Tailored heat treatments transform additively manufactured high‐nitrogen martensitic Cr steel from austenitic as‐built condition to high‐hardness states. Isothermal bainitizing at 250°C generates an ultrafine nanostructure and achieves higher hardness than conventional hardening and tempering, highlighting a promising postprocessing route for laser ...
