Simple Access to a Series of Higher Substituted Pentafluoroorthotellurate‐Based Silanes

Chemistry – A European Journal, EarlyView.
The pentafluoroorthotellurate ligand was introduced to organo silanes. A variety of silanes with the formular RxSi(OTeF5)4–x were synthesized and characterized via spectroscopic techniques and sc‐XRD. The influence of the number of OTeF5 groups on structural properties as well as the fluoride ion affinities (FIA) has been studied and compared to other ...

Kinetic Contribution to the Arbitrary Order Odd Frequency Moments of the Dynamic Structure Factor

Contributions to Plasma Physics, EarlyView.
ABSTRACT An exact expression is derived for the kinetic contribution to the odd (arbitrary order) frequency moments of the dynamic structure factor via a finite summation that features averages of even (all lower orders) powers of the momentum over the exact momentum distribution.

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

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system

Deep Underground Science and Engineering, EarlyView.
The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

High‐Entropy Metal Phosphide for Efficient Hydrogen Conversion Reactions

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this study, high‐entropy metal phosphide nanoparticles were synthesized via a cation‐binding phosphate–resin heating treatment strategy. Mn incorporation in Co0.62Fe0.20Ni0.14Cu0.23Mn0.38P effectively optimized the electronic structure, accelerated electron transfer among metal sites, lowered the free energy of hydrogen adsorption/desorption, and ...

Crustal structure of the Arteaga Complex, Michoacán, southern Mexico, from gravity and magnetics

Geofísica Internacional, 1997
The Arteaga region, Michoacán, southern Mexico is one of the few areas with basement outcrops in the Guerrero ter¬rane. The Zihuatanejo subterrane is characterized by Late Jurassic-Early Cretaceous island-arc volcanosedimentary se¬quences that rest ...
