Surfaces with wide-angle high emissivity in the infrared spectrum are important for applications in radiative cooling, thermophotovoltaics, and spacecraft thermal management. Here, near perfect, broadband, omnidirectional emissivity is realized via s

The hydrodynamic mechanisms associated with the formation of femtosecond laser induced ripples on copper for two angles of incidence are reported. Laser pulse length used for this work is 35 fs. A revised two-temperature model is presented that compr

A novel blast wave mitigation device was investigated experimentally in this paper. The device consists of a piston-cylinder assembly. A shock wave is induced within the cylinder when a blast wave impacts on the piston. The shock wave propagates insi

Appendicitis after colonoscopy is rare, with an estimated incidence of 3.8 cases per 10 000 colonoscopies. Herein, we report a 56-year-old female who visited the emergency department with a history of diffuse abdominal pain and nausea 8 h after a scr

In this study, a vapor chamber - thermal diode apparatus is fabricated and tested. The system’s components are laser-functionalized, wickless, and wettability-patterned copper plates. This is the first thermal management component that is completel
