    • Effect of Excess Calcium Content on the Dissolution Rate of Dolomites in Hydrochloric Acid 
      Ivanishin, Igor (2020-12-01)
      Dolomitic reservoir rocks of different age, origin, and composition were analyzed using several techniques, including: powder X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM), ...
    • Metalliferous Deposits within Newfoundland Ophiolite Complexes 
      Copp, John F. (1978)
      Because of their apparent metalliferous concentrations, six metamorphosed sedimentary rocks were collected from the island of Newfoundland. The samples were studied in order to determine the origins of the metals contained ...
    • Modeling Stacking Disorder in Soil Kaolinite 
      Fashina, Bidemi Tokunbo (2018-10-09)
      Kaolinite is ubiquitous in soils and is the dominant clay mineral in highly weathered soils such as Oxisols and Ultisols. The determinative roles of mineral structures at the atomic level in their surface properties, their ...
    • NMR study of Ni50+xTi50-x Strain-Glass 
      Li, Rui; Santiago, Jacob; Salas, Daniel; Karaman, Ibrahim; Ross, Joseph Jr (Physical Review, 2023)
      We studied Ni50+xTi50−x with compositions up to x=2, performing 47Ti and 49Ti nuclear magnetic resonance (NMR) measurements from 4 to 400 K. For large x in this system, a strain glass appears in which frozen ferroelastic ...
    • Strengthening Mechanisms of Sputtered Copper, Cobalt and Their Nanocomposites 
      Liu, Yue (2014-04-28)
      Low energy planar defects such as twin boundaries have been employed to strengthen materials effectively with insignificant loss of the conductivity and ductility. High density growth twins can be formed in low stacking ...
