The Georgia Institute of Technology is a public research university in Atlanta, Georgia, in the United States. It is a part of the University System of Georgia and has satellite campuses in Savannah, Georgia; Metz, France; Athlone, Ireland; Shanghai, China; and Singapore.The educational institution was founded in 1885 as the Georgia School of Technology as part of Reconstruction plans to build an industrial economy in the post-Civil War Southern United States. Initially, it offered only a degree in mechanical engineering. By 1901, its curriculum had expanded to include electrical, civil, and chemical engineering. In 1948, the school changed its name to reflect its evolution from a trade school to a larger and more capable technical institute and research university.Today, Georgia Tech is organized into six colleges and contains about 31 departments/units, with emphasis on science and technology. It is well recognized for its degree programs in engineering, computing, business administration, the science, architecture, and liberal arts.Georgia Tech's main campus occupies part of Midtown Atlanta, bordered by 10th Street to the north and by North Avenue to the south, placing it well in sight of the Atlanta skyline. In 1996, the campus was the site of the athletes' village and a venue for a number of athletic events for the 1996 Summer Olympics. The construction of the Olympic village, along with subsequent gentrification of the surrounding areas, enhanced the campus.Student athletics, both organized and intramural, are a part of student and alumni life. The school's intercollegiate competitive sports teams, the four-time football national champion Yellow Jackets, and the nationally recognized fight song "Ramblin' Wreck from Georgia Tech", have helped keep Georgia Tech in the national spotlight. Georgia Tech fields eight men's and seven women's teams that compete in the NCAA Division I athletics and the Football Bowl Subdivision. Georgia Tech is a member of the Coastal Division in the Atlantic Coast Conference. Wikipedia.

The disclosure provides for electrochemical supercapacitors with high energy densities, based on paired groups of carbon nanotube mounted to conductive substrates. In one variation, the electrochemical supercapacitors are double layer capacitors, or electrochemical double layer capacitors, containing opposing groups of carbon nanotubes on opposing substrates. In another variation, the capacitor is an interdigitated capacitor of alternating electrode containing carbon nanotubes, mounted on a common substrate. Processes and devices are also described.

A triboelectric generator includes a first contact charging member and a second contact charging member. The first contact charging member includes a first contact layer and a conductive electrode layer. The first contact layer includes a material that has a triboelectric series rating indicating a propensity to gain electrons due to a contacting event. The conductive electrode layer is disposed along the back side of the contact layer. The second contact charging member is spaced apart from and disposed oppositely from the first contact charging member. It includes an electrically conductive material layer that has a triboelectric series rating indicating a propensity to lose electrons when contacted by the first contact layer during the contacting event. The electrically conductive material acts as an electrode. A mechanism maintains a space between the first contact charging member and the second contact charging member except when a force is applied thereto.

A microneedle array is provided for administrating a drug or other substance into a biological tissue. The array includes a base substrate; a primary funnel portion extending from one side of the base substrate; and two or more solid microneedles extending from the primary funnel portion, wherein the two or more microneedles comprise the substance of interest. Methods for making an array of microneedles are also provided. The method may include providing a non-porous and gas-permeable mold having a two or more cavities each of which defines a microneedle; filling the cavities with a fluid material which includes a substance of interest and a liquid vehicle; drying the fluid material to remove at least a portion of the liquid vehicle and form a plurality of microneedles that include the substance of interest, wherein the filling is conducted with a pressure differential applied between opposed surfaces of the mold.

An active catheter design incorporating a distal loop coil that is electrically connected to an ultrasonic transducer having a comparable profile. The ultrasonic transducer induces ultrasonic waves at the Larmor frequency at the distal end of a dielectric optical fiber that runs along the active catheter shaft. The optical fiber serves as the transmission line instead of a convention conductor, eliminating the RF induced heating. The dynamic strain generated by the ultrasonic transducer can be measured using optical interferometry by coupling a laser at the proximal end of the optical fiber using the acousto-optical effect. A fiber embedded Bragg reflector grating, for example, can be used for this purpose. The device can also be used for simultaneous temperature measurements among other parameters.

Yellow electrochromic polymers (ECPs) are prepared that display a yellow neutral state and a highly transmissive oxidized state. The ECPs are copolymers where a dyad of dioxyhetereocyclic repeating units alternate with a monad of an aromatic repeating unit. An alternate yellow ECP has an oxidation potential of 450 mV or less and is an alternating copolymer of an acyclic dioxythiophene (AcDOT) or a propylene dioxythiophene (ProDOT) with an aromatic repeating unit that has an electron donating substituent. The yellow ECPs can be processed from solution for electrochromic devices.

Diagnostic devices; systems, methods and computer-readable media store instructions related to determining hemoglobin information using those devices. The methods may include processing a captured image of the reservoir and/or device and the device information to determine color information for the solution and the scale, the color information including one or more color attributes; adjusting the color information for the solution based on the color information for the scale; and determining hemoglobin information (e.g., hemoglobin level, disease state and/or calculated hematocrit) based on the adjusted color information and a stored profile information associated with the device information.

A silicon-based anode comprising silicon, a carbon coating that coats the surface of the silicon, a polyvinyl acid that binds to at least a portion of the silicon, and vinylene carbonate that seals the interface between the silicon and the polyvinyl acid. Because of its properties, polyvinyl acid binders offer improved anode stability, tunable properties, and many other attractive attributes for silicon-based anodes, which enable the anode to withstand silicon cycles of expansion and contraction during charging and discharging.

It has been more than 20 years since Bialek and colleagues published a landmark paper asking a seemingly innocuous question: what can we extract about the outside world from the spiking activity of sensory neurons? Can we read the neural code? Although this seemingly simple question has helped us shed light on the neural code, we still do not understand the anatomical and neurophysiological constraints that enable these codes to propagate across synapses and form the basis for computations that we need to interact with our environment. The sensitivity of neuronal activity to the timing of synaptic inputs naturally suggests that synchrony determines the form of the neural code, and, in turn, regulation of synchrony is a critical element in 'writing' the neural code through the artificial control of microcircuits to activate downstream structures. In this way, reading and writing the neural code are inextricably linked. © 2013 Nature America, Inc.
