Bimetallic (NiFe) and Trimetallic (NiFeCr) Nanoalloys from Metal Oxides Using a Microwave Hydrogen Plasma

Advanced Engineering Materials, EarlyView.
Bimetallic (NiFe) and trimetallic (NiFeCr) nanoalloys (NAs) are synthesized using corresponding oxide mixtures using microwave hydrogen plasma within a few milliseconds. The process simultaneously 1) reduces metal oxides to metals; 2) downsizes the particles from micrometers to nanometers; and 3) blends the metals to form NAs.

Polarons, Dressed Molecules, and Itinerant Ferromagnetism in ultracold Fermi gases [PDF]

, 2014
In this review, we discuss the properties of a few impurity atoms immersed in a gas of ultracold fermions, the so-called Fermi polaron problem. On one side, this many-body system is appealing because it can be described almost exactly with simple ...

Sustainable Synthesis of Bio‐Based Magnetic and Conductive Wood for Electromagnetic Interference Shielding Applications

Advanced Engineering Materials, EarlyView.
A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation

Magneto-capacitance probing of the many-particle states in InAs dots

, 2004
We use frequency-dependent capacitance-voltage spectroscopy to measure the tunneling probability into self-assembled InAs quantum dots. Using an in-plane magnetic field of variable strength and orientation, we are able to obtain information on the quasi ...

Population of Nonmetallic Inclusions in Liquid High‐Silicon Electrical Steel in Contact With MgO–C Refractories Based on Recyclates and Environmentally Friendly Binders

Advanced Engineering Materials, EarlyView.
The formation of nonmetallic inclusions (NMIs) was investigated in this study, carrying out immersion tests for 30 min at a temperature of 1600°C with liquid high‐silicon electrical steel (Si ≈ 3 mass‐%) and different MgO–C refractories. Conventional MgO–C refractories were considered, as well as MgO–C refractories containing MgO–C recyclate and ...

Anomalous Particle Size Dependence of Magnetic Relaxation Phenomena in Goethite Nanoparticles

Croatica Chemica Acta, 2015
By use of Mössbauer spectroscopy we have studied the magnetic properties of samples of goethite nanoparticles with different particle size. The spectra are influenced by fluctuations of the magnetization directions, but the size dependence is not in ...
