This paper presents a novel microtechnology, magnetic micropallets, for the recovery of single adherent cells from large mixed populations. This work significantly advances the base technology, the micropallet array, which itself is effective for the analysis of adherent cell populations and isolation and selection of individual cells. We greatly improved the method of recovery of individual mi...

Ferromagnetic carbon-coated cobalt nanoparticles have been ligated by a covalent or non-covalent strategy with dendrons or polymers bearing amino-, hydroxy- or polyether-functionalities, aiming at synthesizing materials that are dispersible in aqueous solutions, being a prerequisite for applications in biomedicine. Most efficiently for this purpose proved to be a covalently anchored polyethylen...

The investigation of a sizable thermal enhancement of magnetization is put forward for uniaxial ferromagnetic nanoparticles that are placed in a rotating magnetic field. We elucidate the nature of this phenomenon and evaluate the resonant frequency dependence of the induced magnetization. Moreover, we reveal the role of magnetic dipolar interactions, point out potential applications, and reason...

In this paper, crystalline iron-nickel alloy nanostructures were successfully prepared from two cationic pyridinium derivatives as soft templates in solution. The crystal structure and micrograph of FeNi alloy nanostructures were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy, and the content was confirmed by energy-dispersive spectrometry....

The filtered cathodic vacuum arc technique was employed to deposit magnetic films such as FeNi on silicon substrate. Using the normal cathode design, tetrahedral amorphous carbon and metals films can be deposited. If a magnetic target is used, the arc spot always preferably moves to the edge of the target and then extinguishes. Therefore, the arc is not stable and no film can be deposited. A ca...

Layered Double Hydroxides In article number 2103318, Wei Chen and co-workers fabricate 2D FeNi layered double hydroxide nanosheets (≈1.34 nm in thickness) packed with 1D FeNi-MOFs nanorods (≈1.3 μm length). This unique 2D/1D structure displays enhanced electrocatalytic performance for oxygen evolution reaction a low overpotential (272 [email protected] mA cm−2), small Tafel slope (34.1 mV dec−1...

A semiconductor/metal nanocomposite is composed of a porosified silicon wafer and embedded ferromagnetic nanostructures. The obtained hybrid system possesses the electronic properties of silicon together with the magnetic properties of the incorporated ferromagnetic metal. On the one hand, a transition metal is electrochemically deposited from a metal salt solution into the nanostructured silic...
