Dynamic control of spin-wave propagation
Scientific Reports, 2021 In this work we present a method to dynamically control the propagation of spin-wave packets. By altering an external magnetic field the refraction of the spin wave at a temporal inhomogeneity is enabled.

Architected Various MnO6 Octahedral Layers MnO2 Nanostructures [PDF]
arXiv, 2012 A series of MnO2 unique nanostructures were synthesized by a facile hydrothermal method with microwave-assisted procedures. A novel nanostructure formation mechanism has been proposed, that MnO6 octahedral nuclei and molecular layers can be rearranged into different nanostructured morphologies by restacking and splitting, and then clasping, which is ...

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2009 An alloy system based on iron is described in which it has been possible to create a high density of interfaces by heat treatment alone. The resulting structure consists of a mixture of slender platelets of bainitic ferrite, just 20–40 nm in thickness, embedded in a matrix of carbon-enriched austenite.

Covalently‐Bonded Diaphite Nanoplatelet with Engineered Electronic Properties of Diamond
Advanced Functional Materials, EarlyView.A novel approach to engineering the electronic properties of diamond is reported on the diaphite nanoplatelet consisting of (11¯${{\bar{1}}}$1) planes of diamond nanoplatelet covalently bonded with graphite (0001) planes. The strong sp3/sp2‐hybridized interfacial covalent bonding induces the electron transfer from diamond to graphite, resulting in a ...
