Low-temperature degradation of a Y-TZP ceramic after surface treatments
(Wiley-Blackwell, 2013-11-01)
The purpose of this study was to evaluate the influence of zirconia surface treatments on low-temperature degradation (LTD). Disc-shaped specimens were subjected to one of four surface treatments, denoted as C (controlno ...
Implant surface features as key role on cell behavior
(2022-01-01)
It has been recognized that physical and chemical properties of biomaterial surfaces mediate the quality of extracellular matrix (ECM) that may affect cell behaviors. In nature, ECM is a heterogeneous three-dimensional ...
Surface alterations produced in grinding of austempered ductile iron
(Elsevier, 2015-07-02)
The technological advances achieved in recent decades have allowed to obtain cast parts of ductile iron with no metallurgical defects and of complex shapes and dimensions very close to the final ones. Heat treatments ...
The hydrothermal alteration of the cordón de inacaliri volcanic complex in the framework of the hidden geothermal systems within the pabelloncito graben (Northern Chile)
(MDPI, 2021)
Detailed mineralogical analyses in areas with surface hydrothermal alteration zones associated with recent volcanism (< 1 Ma) in the Central Andean Volcanic Zone could provide key information to unravel the presence of ...
Charge density alterations in human hair fibers: An investigation using electrostatic force microscopy
(2006-04-01)
A new method for high-resolution analyses of hair surface charge density under ambient conditions is presented in this paper. Electrostatic force microscopy (EFM) is used here to analyze changes in surface charge density ...

Stone Sculpture Wear: Alteration/Fragmentation Processes and Their Impact on Carving Traces of Tenon Heads of Chavín de Huántar, Peru
(Cambridge University Press, 2019)
The study of the stone sculpture production process is subject to the preservation and visibility of tool traces and surface finishes. In this article it is proposed that the parameters developed in conservation for the ...
Taphonomic differences in molluscan shell preservation in freshwater environments from the southeastern Pampas, Argentina
(Society for Sedimentary Geology, 2014-12)
Actualistic studies in freshwater environments are scarce, limiting the interpretation of paleoenvironmental information obtained from the fossil record. The objectives of this study are to assess the taphonomic factors ...
