In-Situ Growth of Copper Sulfide Nanocrystals on ...

Single-crystalline copper sulfide (β-Cu2S) nanocrystals (NCs) were grown in situ on multiwalled carbon nanotubes (MWCNTs) by the solvothermal method. The morphology of the Cu2S NCs was varied from spherical particles (av size = 4 nm) to triangular plates (av size = 12 nm) by increasing the concentration of the precursors. The lattice matching between Cu2S and the MWCNTs would be an important ...

In Situ Probing of Stack-Templated Growth of Ultrathin Cu2 ...

Ultrathin two-dimensional (2D) nanomaterials have attracted intense research efforts due to their extraordinary optoelectronic properties. However, the nucleation and growth mechanisms of 2D colloidal nanosheets are still poorly understood. Here, we follow the formation of ultrathin colloidal Cu2–xS nanosheets by in situ small-angle X-ray scattering.

Deformation twinning behaviors of the low stacking fault ...

The in-situ study reveals that the deformation twinning behavior is largely determined by the interplay between twinning and dislocation activities. FeCoNiCrAl 0.1 ingots were prepared by arc melting the constituent elements (> 99.9% purity) in a water-cooled copper hearth under argon atmosphere. The ingots were re-melted five times to ensure ...

Copper silicide/silicon nanowire heterostructures: in situ ...

Abstract. Copper silicide has been studied in the applications of electronic devices and catalysts. In this study, Cu 3 Si/Si nanowire heterostructures were fabricated through solid state reaction in an in situ transmission electron microscope (TEM). The dynamic diffusion of the copper atoms in the growth process and the formation mechanism are characterized.

In situ nano-compression testing of irradiated copper

Still images extracted from a video recorded during in situ TEM compression testing of an irradiated (100) copper pillar 118 nm in diameter are shown in Fig. 2 along with the recorded load – displacement data. The full video is provided as Supporting Video 1.Before contact with the flat diamond punch, the pillar (Fig. 2a) shows a characteristic high density of small irradiation defects.

Is it ok to bend an old 15mm copper pipe in situ ...

Jul 19, 2011· Is it safe to remove the connector and bend the pipe a little bit whilst it's in situ. I reckon it needs to bend approx 20 degrees to the left then the connector will be free of the cupboard. Otherwise it means cutting the pipe and reconnecting it closer to the floor - but I'm concerned it will be a bit stubby.

A Breakthrough in Low-k Barrier/Etch Stop Films for Copper ...

the adhesion of copper to the dielectric and prevents future electromigration issues (improving the device's long-term reliability). Additionally, performing the removal of native copper oxide in situ increases throughput, compared with a two-step process where copper oxides are removed in a dedicated chamber.

Bioleaching of Copper | SpringerLink

Abstract. Natural bioleaching has been taking place for almost as long as the history of the world, but it is only in the last few decades that we have realized that bioleaching is responsible for acid production in some mining wastes, and that this bacterial activity can be used to liberate some metals.

In situ leaching of copper: Challenges and future prospects

In situ leaching offers a potentially attractive way to extract copper from the subsurface without costly fragmentation and processing. Applicability of in situ leaching is limited to deposits where sufficient permeability exists and where the copper and gangue mineralogy is amenable to leaching.
