New research signals big future for quantum radar
A prototype quantum radar that has the potential to detect objects which are invisible to conventional systems has been developed by an international research team led by a quantum information scientist at the University of York. The new breed of radar is a hybrid system that uses quantum correlation between microwave and optical beams to detect objects...
Optical features embedded in marine shells may help develop responsive, transparent displays (w/video)
The blue-rayed limpet is a tiny mollusk that lives in kelp beds along the coasts of Norway, Iceland, the United Kingdom, Portugal, and the Canary Islands. These diminutive organisms — as small as a fingernail — might escape notice entirely, if not for a very conspicuous feature: bright blue dotted lines that run in parallel along the length of their...
2D-NANOLATTICES nanoelectronics project makes important step with silicene
A European research project has made an important step towards the further miniaturisation of nanoelectronics, using a highly-promising new material called silicene. Its goal: to make devices of the future vastly more powerful and energy efficient. Silicene, a new semiconducting material combining properties of silicon and graphene, is one of the most...
Moving molecules write letters
High performance materials for gas storage, thermal insulators or nanomachines need a thorough understanding of the behavior of the material down to the molecular level. Thermodynamics, which have been developed two hundred years ago to increase the efficiency of steam engines, typically observes and averages over a large number of molecules. Now a...
nANO meets water VI: Nanotechnik für die Wasser-Praxis
Am 19. Februar 2015 hieß es wieder "nANO meets water" bei Fraunhofer UMSICHT. Gut 100 Fachleute aus Industrie und Wirtschaft kamen nach Oberhausen, um sich beim Thema Innovationen und Risiken von Nanomaterialien für die Wassertechnik auf den neuesten Stand zu bringen. Auch das Brennpunktthema "Mikroplastik" fand bei allen Beteiligten großen Anklang....
Graphene shows potential as novel anti-cancer therapeutic strategy
University of Manchester scientists have used graphene to target and neutralise cancer stem cells while not harming other cells. This new development opens up the possibility of preventing or treating a broad range of cancers, using a non-toxic material. Writing in the journal ("Graphene oxide selectively...
New nanowire structure absorbs light efficiently
Researchers at Aalto University have developed a new method to implement different types of nanowires side-by-side into a single array on a single substrate. The new technique makes it possible to use different semiconductor materials for the different types of nanowires. 'We have succeeded in combining nanowires grown by the VLS (vapor-liquid-solid)...
Fakir-like graphene
Graphene is a one atom thick sheet of carbon atoms, arranged in a periodic hexagonal lattice. It is famous not only for its remarkable electronic properties, but also for its exceptional mechanical strength and flexibility. To exploit these two last properties, researchers at Université Paris-Sud have draped a graphene sheet over square lattices of...
New projects support research in 'valleytronics'
Two new three-year research projects are supporting the role of the Stanford Institute for Materials and Energy Sciences (SIMES) as a leading center for studying exotic new materials that could enable future innovative electronic and photonic applications. SIMES is a joint institute of Stanford University...
Nanotechnology quick test for Ebola
When diagnosing a case of Ebola, time is of the essence. However, existing diagnostic tests take at least a day or two to yield results, preventing health care workers from quickly determining whether a patient needs immediate treatment and isolation. A new test from MIT researchers could change that: The device, a simple paper strip similar to a pregnancy...
Uncovering the personality of wonder ultrathin materials
A micron-scale optical microgram showing a characteristically triangular molybdenum disulphide ultrathin film grown in York. Following the discovery of graphene, an ultra-thin wonder material made of a carbon sheet of only one atom thickness, a number of other ultra-thin membranes have become the focus of study by nanotechnologists. These ultra-thin...
Unlikely pairs
In the rational world of science, everything can be explained by cause and effect. Sometimes when the cause is known, the ensuing effects can be predicted. But more often scientists try to measure something that “should be there”, or else they discover new phenomena that have no apparent reason or cause. Indeed, most scientific research arises from...
Chromium-centered cycloparaphenylene rings as new tools for making functionalized nanocarbons
Professor Kenichiro Itami, Yasutomo Segawa and Natsumi Kubota of the JST-ERATO Itami Molecular Nanocarbon Project and the Institute of Transformative Bio-Molecules (ITbM), Nagoya University have synthesized novel cycloparaphenylene (CPP) chromium complexes and demonstrated their utility in obtaining monofunctionalized CPPs, which could become useful...
EPSRC unveils world-leading SuperSTEM microscope that sees single atoms

Free-standing monolayers made from protein-bound gold nanoparticles
Free-standing nanoparticle films are of great interest for technical applications, such as the development of nanoelectronic devices. In the journal ("Free-Standing Gold-Nanoparticle Monolayer Film Fabricated by Protein Self-Assembly of α-Synuclein"), Korean scientists have introduced very flexible and stable monolayers of gold nanoparticles made by...
New nanogel for drug delivery
Scientists are interested in using gels to deliver drugs because they can be molded into specific shapes and designed to release their payload over a specified time period. However, current versions aren’t always practical because must be implanted surgically. To help overcome that obstacle, MIT chemical engineers have designed a new type of self-healing...
Microfluidic diamond sensor
Measuring faint magnetic fields is a trillion-dollar business. Gigabytes of data, stored and quickly retrieved from chips the size of a coin, are at the heart of consumer electronics. Even higher data densities can be achieved by enhancing magnetic detection sensitivity---perhaps down to nano-tesla levels. Greater magnetic sensitivity is also useful...
Cheap nanostructured solar cells made with carbon quantum dots from shrimp shells
The materials chitin and chitosan found in the shells are abundant and significantly cheaper to produce than the expensive metals such as ruthenium, which is similar to platinum, that are currently used in making nanostructured solar-cells. Currently the efficiency of solar cells made with these biomass-derived materials is low but if it can be improved...
