Hot nanoparticles for cancer treatments
Nanoparticles have a great deal of potential in medicine: for diagnostics, as a vehicle for active substances or a tool to kill off tumours using heat. ETH Zurich researchers have now developed particles that are relatively easy to produce and have a wide range of applications.

Researchers grow carbon nanofibers using ambient air, without toxic ammonia
Materials science researchers have demonstrated that vertically aligned carbon nanofibers can be manufactured using ambient air, making the manufacturing process safer and less expensive. Vertically aligned carbon nanofibers hold promise for use in gene-delivery tools, sensors, batteries and other technologies.

Unavoidable disorder used to build nanolaser
World around researchers are working to develop nano-optical chips, where light can be controlled. These could be used for future circuits based on light (photons) instead of electrons -- that is photonics instead of electronics. But it has proved to be impossible to achieve perfect photonic nanostructures. Now researchers at the Niels Bohr Institute have shown that imperfect optical chips can be used to produce 'nanolasers,' which is an ultimately compact and energy-efficient light source.

Lightweight construction materials of highest stability thanks to their microarchitecture
KIT researchers have developed microstructured lightweight construction materials of highest stability. Although their density is below that of water, their stability relative to their weight exceeds that of massive materials, such as high-performance steel or aluminum. The lightweight construction materials are inspired by the framework structure of bones and the shell structure of the bees' honeycombs. The results are now presented in the journal PNAS.

Making synthetic diamond crystals in a plasma reactor
Synthetic diamond crystals are of interest to many industrial sectors. Their unique properties make them a suitable material for numerous applications including lenses for high-energy laser optics, X-ray radiation detectors and ophthalmological scalpels. Fraunhofer scientists produce artificial diamonds in all shapes and sizes ranging from discs to three-dimensional shapes and even hollow spheres.

Switching an antibiotic on and off with light
Scientists of the KIT and the University of Kiev have produced an antibiotic, whose biological activity can be controlled with light. Thanks to the robust diarylethene photoswitch, the antimicrobial effect of the peptide mimetic can be applied in a spatially and temporally specific manner. This might open up new options for the treatment of local infections, as side effects are reduced. The researchers present their photoactivable antibiotic with the new photomodule in a 'Very Important Paper' of the journal Angewandte Chemie.

Surprising new way to kill cancer cells
Scientists have demonstrated that cancer cells -- and not normal cells -- can be killed by eliminating either the FAS receptor, also known as CD95, or its binding component, CD95 ligand. The discovery seems counterintuitive because CD95 has previously been defined as a tumor suppressor, scientists said.

The amazing anatomy of James Webb Space Telescope mirrors

New semiconductor holds promise for 2-D physics and electronics
Researchers at Berkeley Lab's Molecular Foundry have discovered a unique new semiconductor, rhenium disulfide, that behaves electronically as if it were a 2-D monolayer even as a 3-D bulk material. This not only opens the door to 2-D electronic applications with a 3D material, it also makes it possible to study 2-D physics with easy-to-make 3-D crystals.

Scientists open a new window into quantum physics with superconductivity in LEDs
A team of University of Toronto physicists led by Alex Hayat has proposed a novel and efficient way to leverage the strange quantum physics phenomenon known as entanglement. The approach would involve combining light-emitting diodes with a superconductor to generate entangled photons and could open up a rich spectrum of new physics as well as devices for quantum technologies, including quantum computers and quantum communication.

Getting rid of bad vibrations
Scanning electron microscopes are extremely sensitive, and even subtle movements going on around them can affect their accuracy. Vibration control tables already exist to dampen these sometimes barely perceptible disturbances. But now a new kind of isolation platform for the first time integrates sensors and actuators into the mount -- resulting in a platform that is more cost-effective and compact than its predecessors. Its designers will be showcasing this new form of isolation at the Hannover Messe (Hall 2, Booth D13) from April 7-11.

Antimony nanocrystals for batteries
Researchers from ETH Zurich and Empa have succeeded for the first time to produce uniform antimony nanocrystals. Tested as components of laboratory batteries, these are able to store a large number of both lithium and sodium ions. These nanomaterials operate with high rate and may eventually be used as alternative anode materials in future high-energy-density batteries.

Bright future for protein nanoprobes
Berkeley Lab researchers at the Molecular Foundry have discovered surprising new rules for creating ultra-bright light-emitting crystals that are less than 10 nanometers in diameter. These ultra-tiny but ultra-bright nanoprobes should be a big asset for biological imaging, especially deep-tissue optical imaging of neurons in the brain.

Roomy cages built from DNA
Scientists at the Harvard's Wyss Institute have built a set of self-assembling DNA cages one-tenth as wide as a bacterium. These DNA nanostructures are some of the largest and most complex structures ever constructed solely from DNA, and they could one day deliver drugs, or house tiny bioreactors or photonic devices that diagnose disease.
