Living in the Mycelial World

open access: yesTopics in Cognitive Science, EarlyView.
Abstract This manuscript documents a systematic ethnomycological analysis of ethnographic archives. Focusing on texts describing human–fungi interactions, I conduct a global, cross‐cultural review of mushroom use, covering 193 societies worldwide. The study reveals diverse mushroom‐related cultural practices, emphasizing the significance of fungi ...

Flotation separation of pyrite and carbonate minerals from a carlin-type gold deposit in Guizhou by a new combined collector and its adsorption mechanism

open access: yesScientific Reports
Flotation is the most common method for effective separation of pyrite and carbonate minerals from Carlin-type gold deposits. The effect of conventional xanthate collector on flotation of a Carlin-type gold mine in Guizhou province is poor, and it can ...

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

open access: yesМинералогия, 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}

Mineralogical characterization of Sn deposits from the Santa Fe District, Bolivia [PDF]

open access: yes, 2015
The Sn-Zn-Pb-Ag Japo-Santa Fe-Morococala ore deposit is located in the Central Andean Belt province. The ore mineralization is hosted in a Paleozoic metasedimentary sequence and porphyritic Oligocene-Miocene igneous rocks. Ore minerals occur in veins and

Pressure-induced phase transition in the electronic structure of palladium nitride

open access: yes, 2010
We present a combined theoretical and experimental study of the electronic structure and equation of state (EOS) of crystalline PdN2. The compound forms above 58 GPa in the pyrite structure and is metastable down to 11 GPa. We show that the EOS cannot be

Structure and electronic properties of new model dinitride systems: A density-functional study of CN2, SiN2, and GeN2

open access: yes, 2003
The dinitrides CN2, SiN2, and GeN2 in assumed pyrite-type structures are studied by means of density functional theory using both ultrasoft pseudopotentials and the augmented spherical wave (ASW) method.
