We demonstrate an optical waveguide device, capable of supporting the high, in-vacuum, power necessary for trapping a single atom or cold ensemble with evanescent fields. Our photonic integrated platforms, suspended membrane waveguides, successfully manages powers 6 mW (500 um span) to nearly 30 (125 over un-tethered span. This platform is compatible laser cooling and magneto-optical traps (MOT...

Argentine ant, Linepithema humile (Mayr), management is constrained, in large part, by polydomy where nestmates are distributed extensively across urban landscapes, particularly within mulch. Management with trap-mulching is a novel approach derived from trap-cropping where ants are repelled from a broad domain of nest sites to smaller defined areas, which are subsequently treated with insectic...

We build a microfluidic trap-based microsphere array device. In the device, we design a novel geometric structure of the trap array and employ the hydrodynamic trapping mechanism to immobilize the microspheres. We develop a comprehensive and robust framework to optimize the values of the geometric parameters to maximize the microsphere arrays’ packing density. We also simultaneously optimize mu...

For evaluation of suspected infectious spondylitis, 19 consecutive patients underwent imaging-guided spine biopsy with needle aspiration and a percutaneous diskectomy device to determine if the diskectomy device provided diagnostic value. In 79% of cases, the diskectomy device yielded a specimen when needle aspiration failed. A significantly greater yield of specimen was observed with the diske...

We report the development of a simple poly(dimethylsiloxane) microfluidic device for high-efficiency trapping and sorting of micron-size particles. In this device, hydrodynamic fluid flow through the sieve-like microfluidic channel sequentially fills the trap positions with particles of the trap size, and particles smaller than the trap size pass through the sieve and are trapped by smaller tra...

BACKGROUND Needle thoracentesis decompression (NTD) is a recommended emergency treatment for tension pneumothorax. Current doctrine recognizes two suitable sites: the second intercostal space in the midclavicular line and the fourth or fifth intercostal space in the anterior axillary line. METHODS A review was conducted of postmortem computed tomography and autopsy results in 16 cases where N...

Abstract Neutron-transmutation doping (NTD) has been demonstrated for the first time in this work substitutional introduction of tin (Sn) shallow donors into two-dimensional (2D) layered indium selenide (InSe) to manipulate electron transfer and charge carrier dynamics. Multidisciplinary study including density functional theory, transient optical absorption, FET devices have carried out reveal...

We report an integrated microfluidic device for fine-scale manipulation and confinement of micro- and nanoscale particles in free-solution. Using this device, single particles are trapped in a stagnation point flow at the junction of two intersecting microchannels. The hydrodynamic trap is based on active flow control at a fluid stagnation point using an integrated on-chip valve in a monolithic...

A simple to implement model is presented to extract interface trap density of graphene field effect transistors. The presence of interface trap states detrimentally affects the device drain current-gate voltage relationship Ids-Vgs. At the moment, there is no analytical method available to extract the interface trap distribution of metal-oxide-graphene field effect transistor (MOGFET) devices. ...
