Advanced Engineering Materials, EarlyView.Bimetallic (NiFe) and trimetallic (NiFeCr) 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.

Imaging of quantum Hall states in ultracold atomic gases
, 2011 We examine off-resonant light scattering from ultracold atoms in the quantum Hall regime. When the light scattering is spin dependent, we show that images formed in the far field can be used to distinguish states of the system.

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

New Tracer for Magnetic Particle Imaging - SPIONs encapsulated in RBCs
Current Directions in Biomedical Engineering, 2018 Superparamagnetic iron oxide nanoparticles, so called SPIONs, are used as tracers in medical imaging, e. g. for magnetic particle imaging (MPI) or magnetic resonance imaging (MRI).

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 ...

Advanced Functional Materials, EarlyView.In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...

A time lens for high resolution neutron time of flight spectrometers
, 2005 We examine in analytic and numeric ways the imaging effects of temporal neutron lenses created by traveling magnetic fields. For fields of parabolic shape we derive the imaging equations, investigate the time-magnification, the evolution of the phase ...

Advanced Functional Materials, EarlyView.The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Magnetic-Particle-Imaging mit mehreren Gradientenstärken [PDF]
, 2018 Die Magnetpartikelbildgebung (engl.Magnetic-Particle-Imaging,MPI) ist ein tomografisches Bildgebungsverfahren mit dem super-paramagnetische Nanopartikel mit einer hohen zeitlichen Auflosung visualisiert werden konnen [1]. Die raumliche Auflosung und die Grose des Bildgebungsbereiches hangen direkt mit der genutzten Gradientenfeldstarke zusammen.
