We present ultra low-cycle fatigue experiments of axisymmetric nano-crystalline gold films of nano-thickness deformed by a spherical indenter using a recently developed freestanding membrane test. Freestanding membranes of gold were centrally deflected using a spherical indenter attached to a MEMS load cell. Fabrication of the films for these experiments yielded films 100 nm thick and 500 μm in...

Nano-silicon is a nanostructured material in which quantum or spatial confinement is the origin of the material's luminescence. When nano-silicon is broken into colloidal crystalline nanoparticles, its luminescence can be tuned across the visible spectrum only when the sizes of the nanoparticles, which are obtained via painstaking filtration methods that are difficult to scale up because of low...

STUDY OBJECTIVE We determine the number and location of freestanding emergency departments (EDs) across the United States and determine the population characteristics of areas where freestanding EDs are located. METHODS We conducted a systematic inventory of US freestanding EDs. For the 3 states with the highest number of freestanding EDs, we linked demographic, insurance, and health services...

Freestanding emergency departments (EDs), which offer emergency medical care at sites separate from hospitals, are a rapidly growing alternative to traditional hospital-based EDs. We evaluated state regulations of freestanding EDs and describe their effect on the EDs' location, staffing, and services. As of December 2015, thirty-two states collectively had 400 freestanding EDs. Twenty-one state...

Atmospheric pressure microwave plasma has the lead in synthesizing freestanding and scalable graphene within seconds without need for high vacuum temperature. However, process is limited utilizing chemical sources synthesis, such as methane ethanol. Herein, usage of an extract a sustainable precursor, that is, Melaleuca alternifolia, commonly known tea tree, first time reported to synthesize na...

We have developed a hygromorphic metal oxide actuator using an electrochemical method to produce a superhydrophilic freestanding nano-capillary forest of titanium oxide with a high aspect ratio (~80). This metal oxide film has an inhomogeneous initial gap at the top and bottom surfaces between the tubes due to flexure during fabrication. The actuation mechanism is as follows. First, when a drop...

Recently, freestanding lms have attracted much attention because they are highly useful in the fabrication of various nanodevices. Freestanding lms can be used on any substrate without deterioration of their own unique properties. Layerby-layer (LBL) deposition has been used widely in the synthesis of freestanding lms, especially of polymer lms with specic physical and mechanical propertie...
