Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

Advanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

Effect of additive concentration and temperature on the tribological performance of eco-friendly bonded MoS2-PEEK solid lubricants for aerospace applications

Results in Surfaces and Interfaces
Spray-bonded molybdenum disulfide (MoS2) coatings are widely used in space and aerospace components for their low friction and wear resistance. Conventional formulations often rely on toxic additives/dopants such as Pb-based compounds and Sb2O3 to ...

Biologic responses to polyetheretherketone (PEEK) wear particles

, 2019
The biological response to wear particles is associated with failure and decreased longevity of total joint replacements. Particles in the size range of 0.1–10 μm are considered the most biologically reactive, particularly submicron-sized polymer ...
