Because of the incidence of voltage pulse trains generated from intrinsic arcs existing during the operation of adjacent disconnectors, several failures in 550 kV class current transformers have been reported across the Brazilian integrated power grid. Based on previous correlated research, the authors…
Introduction: The mechanical nature of nanoelectromechanical (NEM) switches makes them sluggish yet desirable for ultra-low-power, harsh environment applications. Two- and three-terminal NEM switches have been demonstrated using onedimensional, two-dimensional, and thin films, but sub-0.3 V operation…
Shock‐induced transformations of quartz to high‐pressure polymorphs and diaplectic glass are decisive in identifying impact cratering events. Under shock compression, quartz can melt in local hot spots and crystallization of these silica melts under pressure can yield the high‐pressure mineral stishovite.…
Orthodontic tooth movement (OTM) is thought to be impeded by bisphosphonate (BP) therapy, mainly due to increased osteoclast apoptosis and changes in the periodontal ligament (PdL), a connecting tissue between the alveolar bone and teeth. PdL cells, mainly fibroblasts (PdLFs), are crucial regulators…
Whispering gallery mode resonatoren werden für eine Vielzahl unterschiedlicher Anwendungen in der Industrie und im akademischen Bereich eingesetzt. Die Arbeit mit WGM ist mit Hürden wie die Herstellung, Charakterisierung und Anregung verbunden. Das Ziel dieser Arbeit ist es, neue Konzepte vorzustellen,…
