Effect of Implant Design on Fracture Resistance, Mode, and Crystal Structure of One‐ and Two‐Piece Zirconia Implants With Ceramic or Titanium Abutment Screws: An In Vitro Study

Clinical Oral Implants Research, EarlyView.
ABSTRACT Objectives To evaluate the fracture resistance, fracture modes, and crystalline phase changes of zirconia one‐piece implants (OPI) and bone‐level (BLTPI) or tissue‐level, two‐piece implants (TLTPI), with ceramic (C) or titanium (T) abutment screws after dynamic preloading in a moist environment.

Nanoprecipitate characterisation in NiTi and aluminium alloys: A TEM‐based overview

Journal of Microscopy, EarlyView.
Abstract Nanoscale precipitates are central to the functional and mechanical performance of many advanced alloys, yet their characteristics and spatial distributions can be directly resolved only by electron microscopy. In this poster‐style article, focused ion beam‐prepared TEM lamellae are used to provide a microscopy‐focused overview of ...

Evidence of a local BCC‐type coordination of cobalt in FCC taenite of iron meteorites

Meteoritics &Planetary Science, EarlyView.
Abstract Ni, Co, and Fe K‐edge X‐ray absorption fine structure (XAFS) measurements were performed, revealing an unexpected local structure around Co in well‐known iron and stony‐iron meteorites. Cobalt is enriched in kamacite but remains in taenite at concentrations of at least 0.3 atom%.
