Gold nanoparticles for selective and remote heating of β-amyloid protein aggregates
Neus G. Bastús,Marcelo J. Kogan,Roger Amigo,Dolors Grillo-Bosch,Eyleen Araya,Antonio Turiel,Amílcar Labarta,Ernest Giralt,Víctor F. Puntes +8 more
TL;DR: In this paper, the authors used weak microwave fields and gold nanoparticles (AuNP) to remove toxic protein deposits of Aβ1-42 (amyloid deposits) via the combined use of weak microwave field and AuNP without any bulk heating, which can be extended to remove proteins and other aggregates involved in different pathologies.

Characterisation of sugar content in yoghurt by means of microwave spectroscopy
TL;DR: In this article, the complex dielectric permittivity of sugar solutions in yoghurt was measured in the 1-20 GHz microwave frequency range and the relationship between parameters that define both the real and the imaginary part of the Debye relations and the weight fraction of sugar content was obtained.

Electrochemical synthesis of new magnetic mixed oxides of Sr and Fe : Composition, magnetic properties, and microstructure
TL;DR: In this article, an electrochemical method for the preparation of magnetic nanoparticles of new Sr-Fe oxides is presented, which consists of the electrolysis of nitrate or chloride solutions with Sr{sup 2+} and Fe{sup 3+} salts using commercial Fe electrodes.

Electrochemical Route for the Synthesis of New Nanostructured Magnetic Mixed Oxides of Mn, Zn, and Fe from an Acidic Chloride and Nitrate Medium
TL;DR: In this paper, new nanostructured magnetic Mn−Zn−Fe oxides are electrochemically synthesized as precipitates from chloride + nitrate solutions of pH 1.5 with Mn2+, Zn2+, and Fe2+, or Fe3+ at temperatures between 40 and 80 °C using electrodes of commercial iron.
