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

Archaeological 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.

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

ChemPlusChem, 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
