Superslippery islands (but then they get stuck)
It's possible to vary (even dramatically) the sliding properties of atoms on a surface by changing the size and 'compression' of their aggregates: an experimental and theoretical study conducted with the collaboration of SISSA, the Istituto Officina dei Materiali of the CNR (Iom-Cnr-Democritos), ICTP in Trieste, the University of Padua, the University of Modena e Reggio Emilia, and the Istituto Nanoscienze of the CNR (Nano-Cnr) in Modena, has just been published in Nature Nanotechnology.

First solar cell made of highly ordered molecular frameworks
Researchers at KIT have developed a material suited for photovoltaics. For the first time, a functioning organic solar cell consisting of a single component has been produced on the basis of metal-organic framework compounds. The material is highly elastic and might also be used for the flexible coating of clothes and deformable components. This development success is presented on the front page of the journal Angewandte Chemie International Edition.

Biomedical breakthrough: Carbon nanoparticles you can make at home
Researchers have found an easy way to produce carbon nanoparticles that are small enough to evade the body's immune system, reflect light in the near-infrared range for easy detection, and carry payloads of pharmaceutical drugs to targeted tissues. The new approach generates the particles in a few hours and uses only a handful of ingredients, including store-bought molasses.

Researchers design placenta-on-a-chip to better understand pregnancy
National Institutes of Health researchers and their colleagues have developed a 'placenta-on-a-chip' to study the inner workings of the human placenta and its role in pregnancy. The device was designed to imitate, on a micro-level, the structure and function of the placenta and model the transfer of nutrients from mother to fetus. This prototype is one of the latest in a series of organ-on-a-chip technologies developed to accelerate biomedical advances.

Staying cool: Saharan silver ants
Researchers have discovered two strategies that enable Saharan silver ants to stay cool in one of the world's hottest environments. They are the first to demonstrate that the ants use a coat of uniquely shaped hairs to control electromagnetic waves over an extremely broad range from the solar spectrum to the thermal radiation spectrum and that different physical mechanisms are used in different spectral bands to realize the same biological function of reducing body temperature.

X-ray imaging reveals secrets in battery materials
In a new study, researchers explain why one particular cathode material works well at high voltages, while most other cathodes do not. The insights, published in the June 19 issue of the journal Science, could help battery developers design rechargeable lithium-ion batteries that operate at higher voltages.

A new way to image surfaces on the nanoscale
A multi-institutional team of scientists, including a Northwestern University professor of materials science and engineering, has taken an important step in understanding where atoms are located on the surfaces of rough materials, information that could be very useful in diverse commercial applications, such as developing green energy and understanding how materials rust. The team has developed a new imaging technique that uses atomic resolution secondary electron images in a quantitative way to determine the arrangement of atoms on the surface.

Toward nanorobots that swim through blood to deliver drugs (video)
Someday, treating patients with nanorobots could become standard practice to deliver medicine specifically to parts of the body affected by disease. But merely injecting drug-loaded nanoparticles might not always be enough to get them where they need to go. Now scientists are reporting in the ACS journal Nano Letters the development of new nanoswimmers that can move easily through body fluids to their targets.

Cellulose from wood can be printed in 3-D
A group of researchers at Chalmers University of Technology have managed to print and dry three-dimensional objects made entirely by cellulose for the first time with the help of a 3-D bioprinter. They also added carbon nanotubes to create electrically conductive material. The effect is that cellulose and other raw material based on wood will be able to compete with fossil-based plastics and metals in the ongoing additive manufacturing revolution, which started with the introduction of the 3-D printer.

Nanoparticles can be intrinsically left- and right-handed
A team of scientists from ITMO University and Trinity College Dublin published first experimental results showing that ordinary nanocrystals possess intrinsic chirality and can be produced under normal conditions as a half-and-half mixture of mirror images of each other. The discovery of this fundamental property in nanocrystals opens new horizons in nano- and bio-technology and medicine, for instance, for such applications as targeted drug delivery. The results of the study were published in Nano Letters.

Penn researchers develop a new type of gecko-like gripper
Researchers at the University of Pennsylvania are developing a new kind of gripper, motivated by the ability of animals like the gecko to grip and release surfaces. Like the gecko, the gripper has 'tunable adhesion,' meaning that, despite having no moving parts, its effective stickiness can be tuned from strong to weak. Unlike the gecko and other artificial imitators that rely on structures with complex shapes, the Penn team's gripper uses a simpler, two-material structure that is easier to mass-produce.

Buckle up for fast ionic conduction
ETH material engineers found that the performance of ion-conducting ceramic membranes that are so important in industry depends largely on their strain and buckling profiles. For the first time, scientists can now selectively manipulate the buckling profile, and thus the physical properties, allowing new technical applications of these membranes.

World's thinnest lightbulb -- graphene gets bright!
Led by James Hone's group at Columbia Engineering, a team of scientists from Columbia, SNU, and KRISS demonstrated -- for the first time -- an on-chip visible light source using graphene, an atomically thin and perfectly crystalline form of carbon, as a filament. They attached small strips of graphene to metal electrodes, suspended the strips above the substrate, and passed a current through the filaments to cause them to heat up.
