Application

Chemical Synthesis of Monodisperse Magnetic Nanoparticles

Air- and thermally-stable magnetic carbon-coated cobalt nanoparticles (nanomagnets). Carbon shell consists of approximately three graphitic layers and can be chemically functionalized using e.g. diazotization reactions.[1]

Suzuki cross-coupling reactions on the surface of carbon-coated cobalt: expanding the applicability of core-shell nano-magnets.

Chun Ghee Tan et al.

Chemical communications (Cambridge, England), (36), 4297-4299 (2008-09-20)

To develop magnetic nanomaterials applicable to organic synthesis, the Suzuki cross-coupling method was adapted to attach a range of functional groups to carbon-coated core-shell materials via commercially-available substituted arylboronic acids.

TEMPO supported on magnetic C/Co-nanoparticles: a highly active and recyclable organocatalyst.

Alexander Schätz et al.

Chemistry (Weinheim an der Bergstrasse, Germany), 14(27), 8262-8266 (2008-07-31)

TEMPO was grafted on graphene-coated nanobeads with a magnetic cobalt core by using a general applicable "click"-chemistry protocol. The new heterogeneous CoNP-TEMPO emerged as a highly active catalyst for the chemoselective oxidation of primary and secondary alcohols using bleach as

Covalently functionalized cobalt nanoparticles as a platform for magnetic separations in organic synthesis.

Metal ion levels and lymphocyte counts: ASR hip resurfacing prosthesis vs. standard THA: 2-year results from a randomized study.

Jeannette Ø Penny et al.

Acta orthopaedica, 84(2), 130-137 (2013-04-20)

Wear particles from metal-on-metal arthroplasties are under suspicion for adverse effects both locally and systemically, and the DePuy ASR Hip Resurfacing System (RHA) has above-average failure rates. We compared lymphocyte counts in RHA and total hip arthroplasty (THA) and investigated
