Metasomatized lithospheric mantle for Mesozoic giant gold deposits in the North China craton [PDF]

open access: yes, 2020
The origin of giant lode gold deposits of Mesozoic age in the North China craton (NCC) is enigmatic because high-grade metamorphic ancient crust would be highly depleted in gold.

Effect of Platinum Group Metals Deposition on Vitrification in High-Level Radioactive Waste

open access: yesHe huaxue yu fangshe huaxue, 2023
Platinum group metal(PGM) elements such as ruthenium(Ru), rhodium(Rh) and palladium(Pd) in the high-level radioactive waste solution will aggregate and deposit at the bottom of the furnace during the process of vitrification.

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Platinum group element mineralization at Musongati (Burundi) : concentration and Pd-Rh distribution in pentlandite [PDF]

open access: yes, 2017
The mafic-ultramafic intrusions of the Karagwe-Ankole belt in Burundi are considered as a new potential source for platinum group elements (PGE). The intrusions have mainly been studied for their PGE potential with regard to PGE concentration, but the ...

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting
