We developed a method to obtain water-dispersible boron nanoparticles (BNPs) as a potential boron delivery agent for cancer treatment. The 40 nm nanoparticles are prepared by mechanical milling in undecylenic acid followed by ligand exchange with dopamine. These particles can be rendered fluorescent by the attachment of a fluorophore to the primary amine of the dopamine, which could be used to ...

The present work addresses the development of an eco-friendly and cost-efficient protocol for the oxidation of primary and secondary alcohols to the corresponding aldehydes and ketones by mechanical processing under air. Ball milling was shown to promote the quantitative conversion of a broad set of alcohols into carbonyl compounds with no trace of an over-oxidation to carboxylic acids. The mec...

X-ray absorption fine structure(XAFS) is used to investigate the local structural change of Fe60Cu40 and FegoCu20 with the ball milling time. The XAFS results verify that the solid solution of mechanically alloyed Fe-Cu samples are inhomogeneous. We propose that the bcc to fcc structural transformation of Fe small particles of Fe60Cuq0(160h) is induced by interfacial Cu atoms dissolving in smal...

Iron–nickel spinel oxide NiFe2O4 nanoparticles have been prepared by the combination of chemical precipitation and subsequent mechanical milling. For comparison, their analogue obtained by thermal synthesis is also studied. Phase composition and structural properties of iron–nickel oxides are investigated by X-ray diffraction and Mössbauer spectroscopy. Their catalytic behavior in methanol deco...
