A material’s response to an applied magnetic field can be characterized as diamagnetic, paramagnetic, ferromagnetic or antiferromagnetic. This study presents a diagnostic pen with ferrofluid ink ...

It has recently been shown that using external magnetic fields to modulate spin states of single-atom catalysts (SACs) is highly effective—enhancing oxygen evolution reaction magnetocurrent by a ...

The diagnostic pen is designed with mass production in mind. All its parts — from the 3D-printed casing to the replaceable ink reservoir — can be manufactured at low cost. Its components are resilient ...

Geophysicist Daniel Lathrop wants, among other things, to use it to predict when the Earth’s magnetic field will next reverse. Over the course of our planet’s history, the field has flipped ...

Magnetic fields are produced by electrical currents that are generated by various astrophysical objects. The study of magnetic fields seeks to understand their origin, as well as the acceleration ...

Abstract: The rapid development of electromagnetic energy equipment requires strict evaluation of insulation performance under strong magnetic fields. Due to the influence of magnetic fields on ...

A team of researchers at UCLA has developed a high-tech diagnostic pen that can detect signs of Parkinson’s disease with over ...

The observations mark the first time that the polarization of X-rays from a magnetar, neutron stars possessing the most powerful magnetic fields in the known universe, have been measured during an ...

In particular, the NV centre is a single-axis sensor, with limited dynamic range for magnetic field detection. In contrast, the hBN sensor development by the team in Cambridge does not share these ...
