MORE EndNote Web Workshop Sessions

Monday, March 22nd, 2010

The EndNote Web workshop is turning out to be very popular.  As a result, we have added four more sessions in April: Thursday, April 1, 4:00-5:00 p.m. Monday, April 5, 10:00-11:00 a.m. Tuesday, April 6, 12:00-1:00 p.m. Thursday, April 8, 4:00-5:00 p.m. Seating is limited so advanced registration is required.  To register, or for more [...]

Enhanced Thermal Shock Resistance of Ceramics

Monday, March 22nd, 2010

We propose here a new method to make ceramics insensitive to thermal shock up to their melting temperature.  In this method the surface of ceramics was biomimetically roughened into nanofinned surface that creates a thin air layer enveloping the surface of the ceramics during quenching.  This air layer increases the heat transfer resistance of the [...]

Toward On-Chip Resonators in Wireless Communications Devices

Monday, March 22nd, 2010

Vibrating mechanical-signal processors are now widely used in radio-frequency (RF) stages of wireless transceivers.  These resonators typically have a quality factor, Q, in the range 500–10,000.  Because of the comparatively high quality factors, the resultant devices excel in percent bandwidth, insertion loss, stopband rejection, and dynamic range, and exhibit excellent close-to-carrier phase noise that is, [...]

Eliminating Turbulence in Spatially Intermittent Flows

Monday, March 22nd, 2010

Flows through pipes and channels are the most common means to transport fluids in practical applications and equally occur in numerous natural systems.  In general, the transfer of fluids is energetically far more efficient if the motion is smooth and laminar because the friction losses are lower.  However, even at moderate velocities pipe and channel [...]

Ferrous Polycrystalline Shape-Memory Alloy Showing Huge Superelasticity

Monday, March 22nd, 2010

Shape-memory alloys, such as Ni-Ti and Cu-Zn-Al, show a large reversible strain of more than several percent due to superelasticity.  In particular, the Ni-Ti–based alloy, which exhibits some ductility and excellent superelastic strain, is the only superelastic material available for practical applications at present.  We herein describe a ferrous polycrystalline, high-strength, shape-memory alloy exhibiting a [...]

EndNote Web Workshop

Thursday, March 18th, 2010

EndNote Web is a citation manager designed to help users collect, organize, and format sources for citing in research papers.  It is available for free to all UAB students, faculty, and staff through a site license.  Sterne Library is offering an EndNote Web workshop for UAB students, faculty, and staff. Sterne Library Computer Classroom (Room [...]

Going with the Flow

Thursday, March 18th, 2010

The quest to turn the motion of the world’s waterways into a significant source of energy may still be in its nascent stage, but several tidal power projects are making headway.  Whether they operate in lakes, rivers or the oceans, projects attempting to harness the tides share the same mission: to improve the technology and [...]

Transmission of Electrical Signals by Spin-Wave Interconversion in a Magnetic Insulator

Thursday, March 18th, 2010

The energy bandgap of an insulator is large enough to prevent electron excitation and electrical conduction.  But in addition to charge, an electron also has spin, and the collective motion of spin can propagate — and so transfer a signal — in some insulators.  This motion is called a spin wave and is usually excited [...]

A Memadmittance Systems Model for Thin Film Memory Materials

Thursday, March 18th, 2010

In 1971 the memristor was originally postulated as a new non-linear circuit element relating the time integrals of current and voltage.  More recently researchers have linked the theoretical memristor concept to resistance switching behavior of TiO(2-x) thin films.  However, a variety of other thin film materials exhibiting memory resistance effects have also been found to [...]
