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

open access: yesAdvanced 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

Preparation and characterization of natural melanin and its nanocomposite formed by copper doping

open access: yesNano Select, 2022
Natural Melanins have received great interest due to their structural, thermostability, electrochemical and paramagnetic properties. Pure melanin (Mel) is extracted from Nigella Sativa seeds and doped with Copper (Cu‐Mel) to form nano‐composite melanin ...

Asymmetric magnetization splitting in diamond domain structure: Dependence on exchange interaction and anisotropy

open access: yes, 2011
The distributions of magnetization orientation for both Landau and diamond domain structures in nano-rectangles have been investigated by micromagnetic simulation with various exchange coefficient and anisotropy constant.

Current-Nonlinear Hall Effect and Spin-Orbit Torque Magnetization Switching in a Magnetic Topological Insulator. [PDF]

open access: yesPhysical Review Letters, 2016
The current-nonlinear Hall effect or second harmonic Hall voltage is widely used as one of the methods for estimating charge-spin conversion efficiency, which is attributed to the magnetization oscillation by spin-orbit torque (SOT).

Magnetic Pumps [PDF]

open access: yes, 2013
Micropumps can be classified into two general categories: mechanical and nonmechanical micropumps (an excellent review on micropumps can be found elsewhere [1]). In a typical mechanical pump, a membrane is used to produce the pumping action. Nonmechanical micropumps on the other hand generally have no moving parts.

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

open access: yesAdvanced 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 ...

Switching dynamics between metastable ordered magnetic state and nonmagnetic ground state - A possible mechanism for photoinduced ferromagnetism -

open access: yes, 1998
By studying the dynamics of the metastable magnetization of a statistical mechanical model we propose a switching mechanism of photoinduced magnetization.

Observation of current-induced bulk magnetization in elemental tellurium

open access: yesNature Communications, 2017
The magnetoelectric effect in bulk matter is of growing interest both fundamentally and technologically. Since the beginning of the century, the magnetoelectric effect has been studied intensively in multiferroic materials.

Current-induced torques in textured Rashba ferromagnets

open access: yes, 2012
In systems with small spin-orbit coupling, current-induced torques on the magnetization require inhomogeneous magnetization textures. For large spin-orbit coupling, such torques exist even without gradients in the magnetization direction.
