Thermal changes of copper and iron sulphide minerals (I)

The influence of sulphide transport on the growth and properties of copper sulphide films on copper

Diagenetic formation of ferrimagnetic iron sulphide minerals in rapidly deposited marine sediments, South Island, New Zealand

Detailed magnetostratigraphic studies of Late Neogene siliciclastic sediments of the Awatere Group, South Island, New Zealand (41°45'S, 174°05'E) have revealed a wide range of palaeomagnetic behaviour. Examination of rock magnetic properties was undertaken using conventional palaeomagnetic techniques and thermomagnetic, X-ray diffraction and electron microprobe analyses. These analyses indicate...

The mechanism of ultrafast structural switching in superionic copper (I) sulphide nanocrystals.

Superionic materials are multi-component solids with simultaneous characteristics of both a solid and a liquid. Above a critical temperature associated with a structural phase transition, they exhibit liquid-like ionic conductivities and dynamic disorder within a rigid crystalline structure. Broad applications as electrochemical storage materials and resistive switching devices follow from this...

Colloidal synthesis and characterizations of wittichenite copper bismuth sulphide nanocrystals.

Wittichenite (Cu(3)BiS(3)) nanocrystals have been synthesized utilizing a hot-injection method. They have been characterized in detail. Cu(3)BiS(3) nanocrystals possessed a band gap of 1.56 eV, and the corresponding nanocrystal-film shows a clear photoresponse in I-V measurements. Our work illustrates that Cu(3)BiS(3) nanocrystals have potential in the application of solar cells.
