magnets are the oldest functional materials in human civilization.
However, the applications of permanent magnets are still rapidly growing
today. For energy-related applications and green technologies, stronger
permanent magnets are increasingly demanded. Nanostructured hard
magnetic materials are regarded as the next generation of permanent
magnets, based on the theoretical predictions and preliminary
experimental results. However, many technical challenges remain. We have
worked decade long in both the fundamental research and the materials
processing technologies of permanent magnets. Particularly, we started
the bottom-up approaches in fabrication of nanocomposite magnets. A
review will be given in our research in magnetic nanoparticle synthesis
and severe plastic deformation of bulk nanocomposite magnets. A
perspective on fabrication of anisotropic nanocomposite magnets with
super high energy density will be also discussed. 报告人简要介绍:J Ping

dimensional (2D) van der Waals (vdW) materials, consisting of atomically
thin layers, have fascinating physical properties and intriguing
thickness-dependent characteristics. To date, research on these
materials has predominantly focused on various devices based on their
optical and electronic properties, whilst reports on magnetic and
spintronic devices based on 贰D vdW materials are scarce, because vdW
materials with desirable magnetic properties have yet to be found. By
performing anomalous Hall-effect transport measurements, we reveal that
the magnetic properties of single crystalline vdW Fe三GeTe二 vary
dramatically with thickness. Importantly, a single hard magnetic phase
with a near square-shaped magnetic loop, large coercivity (up to 550 mT
at 二 K) and strong perpendicular magnetic anisotropy were all observed
in Fe三GeTe二 nanoflakes. These merits make Fe三GeTe二 the first vdW
ferromagnetic material suitable for fabricating vdW magnetic
heterostructures. Based on this material, various spintronic devices has
been designed and fabricated.报告人简要介绍:Lan Wang was awarded a PhD

题目:REE Critical Materials Recovery by Advanced Magnetic Separation
Nanotechnology

Magneto-caloric power conversion can be used to convert heat into
electricity that up to now was considered as waste. This new technology
therefore has the potential to significantly contribute to the energy
transition on a global scale.

报告人:Professor You Qiang,University of Idaho

With the advent of giant magneto-caloric effects (MCE) that occur in
conjunction with magneto-elastic or magneto-structural phase transition
of first order (FOT), room temperature heat-pump applications became
feasible. In this context the MnFe(P,X) system is of particular interest
as it contains earth abundant ingredients that are not toxic. This
material family derives from the Fe2P compound, a prototypical example
known since a long time to exhibit a sharp but weak FOT at 210 K
(-63°C).

10:00-10:20

Magneto-caloric power-conversion calls for a somewhat different
combination of properties, in particular a large latent heat that is
favourable for a heat-pump, is detrimental for power conversion as a lot
of heat is needed to change the temperature. Yet a large change of
magnetization is required, which suggests one should either employ
materials exhibiting exchange inversion or second order materials.
Magnetically highly responsive materials in combination with the field
generated by a permanent magnet open the way to new technology for
magnetic refrigeration, heat pumps and power generation. Employing the
highly efficient coupling between the degrees of freedom of magnetic
spins and lattice vibrations in a solid, will render energy conversion
and energy generation technologies that get close to the theoretical
limits.

招待广大师生参预!材质科学与工程高校二零一八年3月22二十四日告诉摘录:Rare Earth
Elements (REEs) have unique physicochemical properties that make them
essential elements in many high-tech components, such as electric
vehicle, power generator, M福特ExplorerI, screen display, hydride batteries and
energy storage. Traditional separation methods like centrifugation and
filtration are usually labor-consumptive, uneconomical and environmental
pollutant. Magnetic separation nanotechnology developed in our lab is an
upcoming technique for REE recycling. Magnetic nanosorbents exhibit
special superiority due to convenient separation by an external magnetic
田野(field).Advantages of magnetic nanosorbents are low inventory utilization
of nanosorbents, enhanced sorption efficiency, high selectivity, and low
production of secondary waste. This talk presents the study on our
lab-made magnetic nanosorbents – double coated magnetic nanoparticles
(dMNP) conjugated with diethylene triamine pentaacetic acid (DTPA) and
their potential to be used as effective sorbents to recycle trivalent
lanthanides from aqueous solutions. The REE sorption results show that
the magnetic nanosorbents possess a high stability, fast kinetics, and
high sorption efficiency in harsh environments. The metal sorption on
the nanosorbents is reversible so that the metal-loaded dMNP-DTPA can be
effectively regenerated by the dilute acids. The nanosorbents can be
reused for more than 1五 sorption/desorption cycles, which helps to
offset the synthesis cost and makes this technique cost-effective in REE
recycling. 专家简历:Dr. Qiang is a professor of Physics and
