Possible reason for carcinogenicity of silica dust found
MIPT's scientists partnered with their colleagues from Skoltech in a study that suggests a possible explanation of the toxicity and carcinogenicity , or the 'cancer-causing' properties of silica dust (silicon oxide particles). It turned out that nature defies the predictions of classical chemistry by forming unexpected products of oxidation processes involving silicon nanoparticles. The scientists have shown that silica nanoparticles contain reactive oxygen species that have long been suggested as a possible cause of lung cancer.

Preservation of monuments: Pinpointed repair reduces costs
The Waldbahn railway is a most beautiful railway and listed as a monument. Its viaducts, however, require restoration and exhibit major damage, such as cracks in the reinforced concrete. If the viaduct was restored with standard state-of-the-art methods, the expenditure and costs would be enormous and the monument character would be endangered. The KIT Innovation Hub 'Prevention in Construction' and its partners now succeeded in developing a customized approach to sustainable repair of the viaduct.

World's smallest magnifying glass makes it possible to see chemical bonds between atoms
Using the strange properties of tiny particles of gold, researchers have concentrated light down smaller than a single atom, letting them look at individual chemical bonds inside molecules, and opening up new ways to study light and matter.

Computers made of genetic material?
Tinier than the AIDS virus- - that is currently the circumference of the smallest transistors. The industry has shrunk the central elements of their computer chips to fourteen nanometers in the last sixty years. Conventional methods, however, are hitting physical boundaries. An alternative could be the self-organization of components from molecules and atoms. Scientists at HZDR and Paderborn University have now made an important advance: the physicists conducted a current through gold-plated nanowires, which independently assembled themselves from single DNA strands.

Nano-scale electronics score laboratory victory
Researchers have pioneered a method for growing an atomic scale electronic material at the highest quality ever reported. The technique for synthesizing large sheets of high-performing monolayer tungsten disulfide is a critical step toward developing next-generation transistors, wearable electronics, and even flexible biomedical devices. Tungsten disulfide holds more promise than graphene for 2D transistors and can strongly absorb and emit light, making it ideal for applications in optoelectronics, sensing, and flexible electronics.

Semiconductor-free microelectronics are now possible, thanks to metamaterials
Engineers at the University of California San Diego have fabricated the first semiconductor-free, optically-controlled microelectronic device. Using metamaterials, engineers were able to build a microscale device that shows a 1,000 percent increase in conductivity when activated by low voltage and a low power laser. The discovery paves the way for microelectronic devices that are faster and capable of handling more power, and could also lead to more efficient solar panels.

Major advance in solar cells made from cheap, easy-to-use perovskite
With its ease of manufacture, perovskite has the potential to replace silicon for inexpensive solar cells. But boosting its efficiency to 25 percent -- that of the best, but expensive, silicon cells -- has not been easy. UC Berkeley physicists have now mated two types of perovskite, separated by a single-layer of hexagonal boron nitride, to produce a solar cell that absorbs across the full solar spectrum and achieves a high efficiency of 21.7 percent.

Direct determination of bandgap energy of single cesium lead bromide nanocrystals
An international research group determined directly the relation between the bandgap energy of single cesium lead bromide nanocrystals and their size and shape. By studying individual NCs being either isolated or surrounded by 'neighbors,' they explicitly visualized for the first time band structure modification introduced by effective coupling between semiconductor NCs upon close contact.

'Pressure-welding' nanotubes creates ultrastrong material
MIPT's researchers investigated the possibility of 'gluing' parallel nanotubes to each other, creating a material so durable that it could withstand even the harsh conditions of the aerospace industry. They experimented with multiwall carbon nanotubes using an shear diamond anvil cell to apply torsion. It turned out that shear stress strain in the outer walls of the tubes causes them to connect to each other by covalent bonding, while the inner tubes' structure remains unaffected.

AMBER-led consortium awarded over €4.4 million in highly competitive European funding program
Researchers in Trinity College Dublin will lead an international project worth over €4.4 million under the European-funded 'Future and Emerging Technologies -- Open' program. FET Open funds visionary research and innovation for radically new future technologies, at an early stage, when there are few researchers working in a field. The project will develop a new class of magnetic materials that could enable new, on-chip and chip-to-chip data up to 1,000 times faster than current technology.

On-chip observation of THz graphene plasmons
Researchers developed a technique for imaging THz photocurrents with nanoscale resolution, and applied it to visualize strongly compressed THz waves (plasmons) in a graphene photodetector. The extremely short wavelengths and highly concentrated fields of these plasmons open new venues for the development of miniaturized optoelectronic THz devices (Nature Nanotechnology DOI: 10.1038/NNANO.2016.185)

Nanostructures made of pure gold
Researchers from TU Wien have discovered a novel way to fabricate pure gold nanostructures using an additive direct-write lithography technique. An electron beam is used to turn an auriferous organic compound into pure gold. This new technique can now be used to create nanostructures, which are needed for many applications in electronics and sensor technology. Just like with a 3-D printer on the nanoscale, almost arbitrary shapes can be created.

Nanosensors on the alert for terrorist threats
MIPT's scientists offer a promising gas sensor composition. They say that choosing the right materials could easily mean making a detection system 10 times more efficient. They believe binary metal oxide sensors open up great prospects. In such systems, one component provides a high electron density in the conduction band and another acts as a strong catalyst. Effective and selective gas sensors could be used, among other things, to identify terrorist threats and detect environmental pollutants.

'Nanoparticle taxicab' materials can identify, collect and transport debris on surfaces
Inspired by proteins that can recognize dangerous microbes and debris, then engulf such material to get rid of it, polymer scientists led by Todd Emrick at the University of Massachusetts Amherst have developed new polymer-stabilized droplet carriers that can identify and encapsulate nanoparticles for transport in a cell, a kind of 'pick up and drop off' service that represents the first successful translation of this biological process in a materials context.

Chemists create clusters of organelles by mimicking nature
Scientists from the University of Basel have succeeded in organizing spherical compartments into clusters mimicking the way natural organelles would create complex structures. They managed to connect the synthetic compartments by creating bridges made of DNA between them. This represents an important step towards the realization of so-called molecular factories. The journal Nano Letters has published their results.
