Designing new piezoelectric materials
Polymer-based piezoelectric materials are currently the object of great interest in the world of industry because they enable their use in new applications in sectors such as transport and aeronautics, amongst others.   view more (2007-10-25)

Varnish measures pressure and vibrations
Despite the use of computer simulation, wind tunnel testing is still required to measure pressure changes and airflow speeds on the surfaces of new aircraft and automobile prototypes. Such testing is now done less with smoke visualization and threads but more frequently with high-tech sensors which... view more (2003-02-20)

Nanowire generates power by harvesting energy from the environment
As the sizes of sensor networks and mobile devices shrink toward the microscale, and even nanoscale, there is a growing need for suitable power sources. Because even the tiniest battery is too big to be used in nanoscale devices, scientists are exploring nanosize systems that can salvage energy... view more (2007-09-28)

Digital mammography results in technologists' time savings but physician time loss
Digital mammography saves technologists' time, but increases physician time compared to film screen mammography, a new study shows.   view more (2006-07-19)

Sandia experimental package of piezoelectric films to be part of NASA space station experiment
For the past three years a Sandia research team headed by Mat Celina has been investigating the performance of various piezoelectric polymer films that might one day serve as ultra-light mirrors in space telescopes.   view more (2006-08-10)

3D Sound Systems Using Groundbreaking Piezoelectric Springs
Piezoelectric materials such as quartz are used in digital watches and computers to produce stable vibrations at high frequencies. Polycrystaline ceramics, such as PZT (lead zirconate titanate), can be made to mimic the behaviour of these natural monocrystaline materials by polarising the crystals... view more (1999-11-29)

Materials World - December 1999 Issue
3D Sound Systems Using Groundbreaking Piezoelectric Springs Digital speakers that can project three dimensional sound across a room are being developed using springs built from piezoelectric ceramics. Applying an electrical current to the material forces the spring to expand causing a vibration... view more (1999-11-30)

Obtaining high performance coatings through simple latex film simulations
In the formation of high performance coatings, it is known that the process whereby a film forms from a colloidal dispersion is a key step.   view more (2005-11-28)

University horrifies film-goers
The University of Southampton is sending shivers down the spines of film-goers and lovers of vampires, zombies and serial killers in a major season of classic horror films at the National Film Theatre in London this autumn.   view more (2004-11-11)

Supporting the British 'B' Movie
This week sees The Times BFI British Film Festival get underway, and all eyes will be on the achievements of the UK film industry. But that's unlikely to include any attention to the low-budget supporting features, or 'B' movies that helped kick-start the careers of film legends like Sir John Mills... view more (2004-10-08)

Liquid crystal multilayer study promises improvements in manufacturing techniques for LCD's
In order to successfully fabricate a commercial Liquid Crystal Display, uniform orientation of the liquid crystal (LC) molecules is required.   view more (2005-10-12)

Sharper pictures for the dream factory
Computer-generated special effects are a staple of contemporary film production. Digital images introduce complications, however, once it comes to projecting them onto movie screens in high quality. The majority of projectors still work with standard 35 mm film, which means that digital image... view more (2002-11-14)

Media invite: Live performances and debates at `Sounding Out` - an international symposium on sound.
Journalists are invited to the first ever international symposium on sound being held at Staffordshire University in Stoke-on-Trent this Thursday, Friday and Saturday (July 11 - 13). The event will bring together film and radio professionals with academics to debate the role of sound in today`s... view more (2002-07-09)

Cine film recorder wins technical award
Movies like "Harry Potter" were copied using a new technology that has itself recently become a Hollywood star: the ARRILASER Film Recorder. The Academy of Motion Picture Arts and Sciences has honored the technology with its Scientific and Technical Award. Computer-generated special effects are a... view more (2002-03-05)

Precision bonding makes tiny high performance actuators possible
Using a new precision bonding process they developed, Penn State researchers have designed and fabricated tiny new piezoelectric microactuators - the largest only a hair's breadth wide - based on coupling commercially available materials with existing micromachining technology.   view more (2005-10-04)

Music students break the silence on classic films
A silent film classic is to get a 21st-century update with the addition of a new musical score written and performed by members of the University of Sussex music department. The University of Sussex Twentieth Century Ensemble takes to the main stage at the Gardner Arts Centre on Thursday 10 June at... view more (2004-06-02)

Nanogenerators convert mechanical energy to electricity for self-powered devices
Researchers have developed a new technique for powering nanometer-scale devices without the need for bulky energy sources such as batteries.   view more (2006-04-14)

Knitting by the guillotine
Madame Defarge and the other women who knitted while they watched people being guillotined during the French Revolution were probably not troubled by flashbacks of the event afterwards. Dr Emily Holmes, currently at the Medical Research Council's Cognition and Brain Sciences Unit, Cambridge, and... view more (2004-04-15)

Visualizing atomic-scale acoustic wavesin nanostructures
Acoustic waves play many everyday roles - from communication between people to ultrasound imaging. Now the highest frequency acoustic waves in materials, with nearly atomic-scale wavelengths, promise to be useful probes of nanostructures such as LED lights.   view more (2008-07-07)

Pass the popcorn! Study finds that film enjoyment is contagious
Loud commentary and cell phone fumbling may be distracting, but new research from the Journal of Consumer Research suggests that the presence of other people may enhance our movie-watching experiences.   view more (2007-12-05)

New small-scale generator produces alternating current by stretching zinc oxide wires
Researchers have developed a new type of small-scale electric power generator able to produce alternating current through the cyclical stretching and releasing of zinc oxide wires encapsulated in a flexible plastic substrate with two ends bonded.   view more (2008-11-10)

Nanotechnology film on national release
Sheffield is a world leader in nanotechnology research, and now it is also taking a leading role in educating the general public in the importance of this science. Experts from the city's two Universities have made a short film about how nanotechnology affects everyday life, which will be a central... view more (2005-02-22)

New material lubricates itself
A highly durable and moreover self-lubricating material has seen the light of day at a thin film laboratory at Linköping University. It is an alloy of boron suboxide and yttrium, BOY, and was grown by the physicist Denis Music. The discovery is put forward in his doctoral dissertation. The... view more (2003-09-25)

UVa Participates in Landmark Breast Cancer Screening Trial
Digital mammography that uses computers to detect breast cancer found significantly (up to 28%) more cancers than screen film mammography in women 50 and younger, premenopausal and perimenopausal women, and women with dense breasts, according to results from one of the largest breast cancer... view more (2005-09-21)
