The Architecture of Large Kurgans of the Scythians and Their Periphery: A Challenge for Magnetometer Prospections in the Eurasian Steppe Belt

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT The burial mounds of the early Iron Age, which we will refer to below as kurgans, from the nomadic equestrian warriors of Eurasia, form a very complex group of archaeological monuments. Archaeological excavations in Aržan 2 (Siberia) and Aleksandropol (Ukraine) show that the large burial mounds are complex architectural constructions.

Expert Perspective: How, When, and Why to Potentially Stop Antiresorptive Drugs in Osteoporosis

open access: yesArthritis &Rheumatology, EarlyView.
Osteoporosis is a chronic disease, and antiresorptive treatments are often continued for many years. Despite their established efficacy in reducing fracture risk, the most commonly used antiresorptive treatments, bisphosphonates and denosumab, have short‐ and long‐term risks that, coupled with their benefits and other unique characteristics, influence ...

Interplay Between Lithium Intercalation and Plating During Fast‐Charging of Lithium‐Ion Batteries Investigated by Operando NMR Spectroscopy

open access: yesBatteries &Supercaps, Accepted Article.
During fast charging, metallic lithium can form on the negative graphite electrode, compromising both cycle life and safety. After deposition, plated lithium can re‐intercalate within graphite, be disconnected or chemically oxidized. To better understand these reactions and their kinetics, operando measurements on cells with electrochemical ...

Using the HClO4–H2O2 System for Efficient Platinum Leaching: Optimal Conditions and Kinetics

open access: yesChemPlusChem, EarlyView.
GA: The platinum leaching using HClO4 and H2O2 is studied. For each HClO4 concentration, an H2O2/HClO4 = 2.5 ratio optimizes the kinetics. The best operating conditions are ≈70 °C, [HClO4] 3 m, and [H2O2] 7.2 m. The leaching process is governed by diffusion in the boundary layer and chemical reaction. In this new extraction process, Cl2(g) is generated

Intensification in pastoralist cereal use coincides with the expansion of trans-regional networks in the Eurasian Steppe

open access: yes, 2019
The pace of transmission of domesticated cereals, including millet from China as well as wheat and barley from southwest Asia, throughout the vast pastoralist landscapes of the Eurasian Steppe (ES) is unclear.

Resonance‐induced restoration of rock permeability degraded by heavy components of crude oil

open access: yesDeep Underground Science and Engineering, EarlyView.
Resonance‐induced changes occur in filtration properties of sedimentary rocks in crude paraffin oil flow under acoustic vibrations. Experimental data on (a) pressure drop; (b) permeability; (c) pressure at the rock inlet; and (d) pressure at the rock outlet are presented.
