Ferromagnetic Type-II Weyl Semimetal in Pyrite Chromium Dioxide

, 2017
Magnetic topological materials have recently drawn significant importance and interest, due to their topologically nontrivial electronic structure within spontaneous magnetic moments and band inversion.

ZONATION OF FORM AND COMPOSITION OF PYRITE CRYSTALS OF THE BEREZOVSKY GOLD DEPOSIT (URALS) [PDF]

Минералогия, 2018
Morphology, zonation and composition of pyrite crystals from quartz veins, beresites and listvenites of the Berezovsky gold deposit are examined. During the crystallization, the pyrite forms changed following a relatively simple scheme {111} → {111}+{100}

Synthesis of Pure Micro- and Nanopyrite and Their Application for As (III) Removal from Aqueous Solution

Advances in Materials Science and Engineering, 2016
Arsenic is one of the materials that has a worldwide concern because of its high toxicity and chronic effects on human health. The existence of arsenic as As (III) is about 56 times poisonous as As (V) and more difficult to process.

Overcoming Polyatomic Interferences in Sulfur Isotope Measurement Using MC‐ICP‐MS

Geostandards and Geoanalytical Research, EarlyView.
Key Points Optimising plasma conditions via the normalised argon index (NAI) reduces polyatomic interferences, allowing accurate sulfur isotope measurement in low‐resolution mode on MC‐ICP‐MS. Low‐resolution mode enhances sensitivity by approximately threefold compared with conventional high‐resolution analysis.

Comparing Groundwater Sampling Devices for Denitrification Assessment Using the N2/Ar Method

Groundwater, EarlyView.
Comparing N2, Ar, and excess‐N2 concentrations of groundwater samples collected with different devices shows that N2, Ar, and excess‐N2 concentrations significantly differ between the sampling devices. Using an electrical submersible pump for sampling yields the highest N2, Ar, and excess‐N2 concentrations.
