In one University of Illinois lab, invisibility is a matter of now you hear it, now you don't. Led by mechanical science and engineering professor Nicholas Fang, Illinois researchers have demonstrated an acoustic cloak, a technology that renders underwater objects invisible to sonar and other ultrasound waves.
A quick look at new Cornell research hints at colorful patchwork quilts, but they are actually pictures of graphene -- one atom-thick sheets of carbon stitched together at tilted interfaces. Researchers have unveiled striking, atomic-resolution details of what graphene 'quilts' look like at the boundaries between patches, and have uncovered key insights into graphene's electrical and mechanical properties.
Researchers are creating a new type of solar cell designed to self-repair like natural photosynthetic systems in plants by using carbon nanotubes and DNA, an approach aimed at increasing service life and reducing cost.
Organic Chemists have always been trying to imitate biology. Although it is possible to make many molecules that imitate biomolecules in terms of structure and function, it remains a challenge to attain the size and form of large biomolecules. An international team at the ETH Zurich has now introduced a branched polymer that resembles the tobacco mosaic virus in size and cylindrical form.
Cumbersome glaucoma tests that require a visit to the ophthalmologist could soon be history thanks to a home test. The self-test instrument has been designed in Eniko Enikov's lab at the UA College of Engineering. Gone are the eye drops and need for a sterilized sensor. In their place is an easy-to-use probe that gently rubs the eyelid and can be used at home.
Muscheln sind wahre Klebekuenstler. Ob am Holz eines Stegs, am Metall eines Schiffrumpfes, an Steinen oder an einem Artgenossen, sie haften ueberall. Forschern um Philip B. Messersmith von der Northwestern University ist es nun gelungen, einen der 'Universal-Klebstoffe' von Muscheln nachzuahmen.
The new material, dubbed a 'nanoscoop' because its shape resembles a cone with a scoop of ice cream on top, can withstand extremely high rates of charge and discharge that would cause conventional electrodes used in today's Li-ion batteries to rapidly deteriorate and fail. The nanoscoop's success lies in its unique material composition, structure, and size.
TU Delft professor of process intensification, Andrzej Stankiewicz, has received an ERC Advanced Investigators Grant of 2.3 million euros from the European Research Council. Professor Stankiewicz will use the money to carry out research on improving chemical reactions at the molecular level in the next five years.
EU-funded scientists in the Netherlands have managed to rapidly control the building blocks of a quantum computer by using an electric field rather than a magnetic one. In addition, the team succeeded in embedding these building blocks, known as quantum bits or qubits, in a semiconductor nanowire.
A five-year, $16-million grant from the National Cancer Institute will take advantage of specialized expertise developed by scientists at Albert Einstein College of Medicine of Yeshiva University and Montefiore, the University Hospital and Academic Medical Center for Einstein.
