    The term in(-)situ visualization denotes a visualization or graphics that is depicted in place, for instance, a sparkline that is embedded into text.. As the dictionaries tell, the adjective or adverb in situ is written as two words. But for concatenated terms in scientific language, oftentimes, in-situ (with a hyphen) is placed in front of the main noun.

    The simulations also reveal drastic differences in deformation mechanisms between nanotwinned copper and twinned aluminium ascribed to stacking-fault energy controlled dislocation-incoherent twin boundary interactions. This study provides new insight into incoherent twin boundary-dominated plasticity in high stacking-fault energy twinned metals.

    AB - Reported here are in situ scanning tunneling microscopy (STM) results of underpotential deposition (UPD) of copper at an iodine-modified Pt(100) electrode. The cyclic voltammograms reveal that an iodine adlayer strongly adsorbed on Pt(100) resulted in a 350 mV delay of Cu deposition with respect to that of a bare Pt(100) electrode.

  • In-situ Copper Recovery in Arizona

    In-situ copper recovery is an environmentally responsible way of extracting copper from the ground. A low-pH solution similar in strength to vinegar slowly dissolves copper in the bedrock. At the same time this solution is being introduced into the copper ore body, it is also being drawn through the ore and extracted.

    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 ...

  • Transformation of shock-compressed copper to the body ...

    Using in situ x-ray diffraction measurements in shock-compressed copper (38–276 GPa), we show that the ambient face-centered-cubic (fcc) structure transforms to the body-centered-cubic (bcc) structure at ∼180 GPa. Additionally, stacking fault (SF) abundance in shock-compressed copper increases with compression, reaching ∼10% at the onset of the fcc-bcc phase transition.

    A Letter to the Editor was recently published in The Northern Miner about in-situ leaching: "It was recently reported in the Financial Post that in-situ leaching of copper is an 'unproven technology'. But after personally spending five years working at the in-situ copper leaching operation at San Manuel, Arizona, I can state that it has definitely been proven."

    A method is presented of in situ measurements of stacking fault densities in shocked face-centred-cubic (FCC) crystals using x-ray diffraction. Using results from both the second and fourth diffraction orders, wherein shifts in the Bragg peaks due to faulting are accounted for, we calculated fault densities present in a molecular dynamics (MD) simulation of shocked single crystal of copper.

  • In situ leach - Wikipedia

    In-situ leaching (ISL), also called in-situ recovery (ISR) or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ.In situ leach works by artificially dissolving minerals occurring naturally in a solid state. For recovery of material occurring naturally in solution, see: Brine mining.
