Structural Design and Analysis of Hybrid Drive Multi-Degree-of-Freedom Motor
Micromachines, 2022 Piezoelectric-driven multi-degree-of-freedom motors can turn off self-lock, withstand high and low temperatures, are small in size and compact in structure, and can easily achieve miniaturization.

Temporal boundaries in electromagnetic materials
New Journal of Physics, 2021 Temporally modulated optical media are important in both abstract and applied situations, such as spacetime transformation optics, relativistic laser–plasma interactions, and dynamic metamaterials. Here we investigate the behaviour of temporal boundaries,

Research on Electromagnetic Radiation Mechanism during Detonation of Energetic Material
Sensors, 2022 In the process of deflagration of energetic materials, strong electromagnetic radiation is generated, which causes the surrounding electronic equipment to fail to work normally.

Advanced Engineering Materials, EarlyView.Multilayer ferrite inductor prototypes are fabricated by cofiring metallized tapes of NiCuZn ferrite and glass‐ceramic composite. Prerequisites for a predictive component simulation are discussed. An automated data‐pipeline stores and semantically links the experimental data acquired in the study according to a domain ontology.

Advanced Engineering Materials, EarlyView.Additive manufacturing of magnesium alloys by laser is difficult because the melting point of the oxide layer is much higher than the evaporation temperature of the metal underneath. Making the oxide layer thinner can solve this problem. Alloying magnesium with strontium makes the oxide layer thinner, especially at 0.5 wt%.

An Electromagnetic Problem [PDF]
Nature, 1909 THE problem noticed by Mr. Comstock in NATURE of November 19, 1908, is an interesting one, but I do not see how the “laws of electricity and conservation of energy require in themselves the discrete structure of electricity or the association of electricity with matter.” The electromagnetic field produced by a uniform spherical sheet of electricity ...
