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

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

Archaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs

Deep Underground Science and Engineering, EarlyView.
A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

Numerical and experimental study on P‐wave propagation across a rock joint with different orientations

Deep Underground Science and Engineering, EarlyView.
Joint orientation significantly affects P‐wave velocity, with the highest velocity at zero‐degree angles, decreasing to 30° as the angle increases. The velocity increases slightly from 30 to 45 degrees but sharply decreases from 45 to 90 degrees. Abstract Determination of the required parameters in different science contexts using the ultrasonic wave ...

Possible role of microtubules in vesicular transport of matrix protein during sea urchin larval biomineralization

Developmental Dynamics, EarlyView.
Abstract Background Biomineralization is a vital biological process through which organisms produce mineralized structures such as shells, skeletons, and teeth. Microtubules are essential for biomineralization in various eukaryotic species; however, their specific roles in this process remain unclear.

Oxidative Stability and Molecular Reactivity of Biodiesel from Castor and Cottonseed Oil Blends by Homogeneous and Heterogeneous Catalysis

Energy Technology, EarlyView.
The oxidative stability of biodiesel from homogeneous and heterogeneous catalysis of castor/cottonseed oil blends is studied. Castor oil's ricinoleic acid improves oxidative stability, acting as a natural antioxidant. Yet, HT catalysis led to lower stability due to catalyst leaching.
