Castles and cathedrals, statues and spires - Europe's built environment would not be the same without these witnesses of centuries past. But, eventually, even the hardest stone will crumble. EU-funded researchers have developed innovative nano-materials to improve the preservation of our architectural heritage.
Physicists have used a new imaging technique, electrostatic force microscopy, to resolve the biological debate with evidence from physics, showing that electric charges do indeed propagate along microbial nanowires just as they do in carbon nanotubes, a highly conductive man-made material.
A new study has cracked one mystery of glass to shed light on the mechanism that triggers its deformation before shattering. The study improves understanding of glassy deformation and may accelerate broader application of metallic glass, a moldable, wear-resistant, magnetically exploitable material that is thrice as strong as the mightiest steel and ten times as springy.
Organisms can be negatively affected by plastic nanoparticles, not just in the seas and oceans but in freshwater bodies too. These particles slow the growth of algae, cause deformities in water fleas and impede communication between small organisms and fish.
Researchers have discovered a new self-assembly method for producing defect-free graphene nanoribbons with periodic zigzag-edge regions. In this bottom-up technique, researchers use a copper substrate's unique properties to change the way the precursor molecules react to one another as they assemble into graphene nanoribbons.
To help laser systems overcome loss, operators often pump the system with an overabundance of photons, or light packets, to achieve optical gain. But now engineers have shown a new way to reverse or eliminate such loss by, ironically, adding loss to a laser system to actually reap energy gains. In other words, they've invented a way to win by losing.
Particle physicists have a hard time identifying all the elementary particles created in their particle accelerators. But now researchers have designed a material that makes it much easier to distinguish the particles. The material manipulates the Cherenkov radiation from particles with high momentum so that they get a distinct light cone angle.
Scientists have demonstrated, for the first time, a new type of mirror that forgoes a familiar shiny metallic surface and instead reflects infrared light by using an unusual magnetic property of a non-metallic metamaterial.
UT Arlington engineering professors have received a $451,781 Air Force Office of Scientific Research grant to examine the material surface at the micro- and nano-scale level that will provide clues for predicting fatigue in aircraft parts.
