Transonic turbine blade cascade testing facility [PDF]
17th Aerospace Ground Testing Conference, 1992 NASA LeRC has designed and constructed a new state-of-the-art test facility. This facility, the Transonic Turbine Blade Cascade, is used to evaluate the aerodynamics and heat transfer characteristics of blade geometries for future turbine applications. The facility's capabilities make it unique: no other facility of its kind can combine the high degree

Dental resin composites generate microparticles and impact on gingival keratinocytes—In vitro study
European Journal of Oral Sciences, EarlyView.Abstract Along with our increased understanding of the spread of microplastic pollution, the awareness of microparticle release from medical and dental materials has increased. Still, their effects on human health are largely unknown. As the use of resin composite materials in dentistry continues to increase, it is essential to understand the formation
