Molecules, 2019 To investigate the effect of carbon defects on the hydrophilicity of the whole surface of the coal pyrite, the adsorption of the single H2O molecule at different sites of the coal pyrite surface was studied with the DFT calculation.

Quantum criticality and disorder in the antiferromagnetic critical point of NiS$_{2}$ pyrite [PDF]
arXiv, 2007 A quantum critical point (QCP) between the antiferromagnetic and the paramagnetic phases was realized by applying a hydrostatic pressure of ~ 7 GPa on single crystals of NiS_{2} pyrite with a low residual resistivity, rho_{0}, of 0.5 mu-Omega-cm. We found that the critical behavior of the resistivity, rho, in this clean system contrasts sharply with ...

Archaeometry, EarlyView.Abstract In the Sobolów area, three hoards of the Hallstatt period were discovered, containing ornaments, waste and scrap of tin–lead–bronze alloy, with iron objects in close proximity, possibly indicating the existence of a foundry workshop. They were accompanied by glass beads, an indicator of the settlement of the Lusatian EB‐Ha Culture, found ...

Archaeometry, EarlyView.Abstract Early Byzantine marble objects from Porphyreon and Chhim (Lebanon) were studied to assess the source of raw materials. In all, 66 artefacts, including elements of liturgical furnishings, architectural elements and daily use objects, were examined using optical, cathodoluminescence and scanning electron microscopy, X‐ray diffraction, and δ13C ...

Flotation Behavior of Complex Sulfide Ores in the Presence of Biodegradable Polymeric Depressants
International Journal of Polymer Science, 2017 In this study, chitosan polymer was tested as a potential selective green depressant of pyrite in the bulk flotation of galena (PbS) and chalcopyrite (CuFeS2) from sphalerite (ZnS) and pyrite (FeS2) using sodium isopropyl xanthate as a collector and 4 ...

PyRIT: A Framework for Security Risk Identification and Red Teaming in Generative AI System [PDF]
arXivGenerative Artificial Intelligence (GenAI) is becoming ubiquitous in our daily lives. The increase in computational power and data availability has led to a proliferation of both single- and multi-modal models. As the GenAI ecosystem matures, the need for extensible and model-agnostic risk identification frameworks is growing.
