Study on vibration isolation effect of different vibration isolation structures
Advances in Engineering Research Possibilities and ChallengesThis study investigates the effectiveness of open, EPS-filled, and sand-filled trenches in isolating ground vibrations using the finite element numerical sim-ulation method. A three-dimensional finite element model was established to analyze the attenuation of vibration acceleration induced by different barrier types.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
Advanced Materials, EarlyView.The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Transmission of Vibration into Vibration-Isolated Buildings
Journal of Low Frequency Noise, Vibration and Active Control, 1991 Buildings constructed above or near underground and surface roads and railways often include some type of vibration isolation in their foundations. The effectiveness of such isolation measures is usually calculated by treating the building as a rigid block and the resulting mass-spring-damper system as a single-degree-of-freedom oscillator whose ...
