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 have the least influence on air flows. Film... view more... (2003-02-20)
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)
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 from the environment. view more (2007-09-28)
Interpretation Time for Screening Digital Mammograms: Is it Efficient?
Digital mammograms take longer to interpret than film-screen mammograms, according to a study performed at The University of Texas M.D. Anderson Cancer Center in Houston, Texas. view more (2009-01-07)
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 within the ceramic. This is done by applying an... 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 that produces a coherent sound image away from the... 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 and Sir Michael Caine. According to one... 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)
Charging ahead: University of Houston team revealing secrets of electricity-producing materials
Much like humans, materials are capable of some pretty remarkable things when they're placed under pressure. In fact, under the right conditions, materials can even produce electricity. view more (2009-07-28)
Berkeley Researchers Take the Lead Out of Piezoelectrics
There is good news for the global effort to reduce the amount of lead in the environment and for the growing array of technologies that rely upon the piezoelectric effect. view more (2009-11-16)
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 sequences must be transferred frame by frame onto... 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 media. The media may be particularly interested in... 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 staple of contemporary film production. Digital... view more... (2002-03-05)
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 8pm. One of the highlights of an entertaining and... view more...

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)
Switch to Digital Mammography Leads to Increased Cancer Detection Rates
The use of digital mammography equipment alone is responsible for an increased number of breast cancers detected at a community-based mammography facility, according to a study performed at San Luis Diagnostic Center in San Luis Obispo, CA. view more (2009-08-04)
