A 2023 randomized controlled trial in the Journal of Dentistry found that the bulk-fill base technique reduced procedure time ...

Abstract: We have created bidirectional high-performance top- and bottom-emitting vertical-cavity surface-emitting lasers (VCSELs) from a single epitaxial wafer. Using a spatially selective oxidation ...

In this paper, we show that patterned metallic surfaces can support localized resonant modes if a suitable defect in the periodicity of the structure is introduced. For those modes, optical losses due ...

What is a Cavity? A cavity is a small area of tooth decay that forms holes in the hard surface of teeth. If untreated, cavities can deepen, leading to infections or dental emergencies. Kunik ...

Some mechanisms involved in osseointegration depend on whether the implant surface is smooth or rough, since cells react differently to these conditions. Fibroblasts and epithelial cells adhere more ...
