Science Advances
Study yields new knowledge about materials for ultrasound and other applications
Scientists at the Department of Energy's Oak Ridge National Laboratory and their research partners have used neutron scattering to discover the key to piezoelectric excellence in the newer materials, which are called relaxor-based ferroelectrics. (A ferroelectric material has electrical polarization that is reversed by application of an electric field.) Their findings, published online in the journal Science Advances, may provide knowledge needed to accelerate the design of functional materials for diverse applications.

'Nano-kebab' fabric breaks down chemical warfare agents
Researchers have created a fabric material containing nanoscale fibers that are capable of degrading chemical warfare agents (CWAs). Uniform coatings of metal-organic frameworks (MOFs) were synthesized on top of the nanofibers, forming unique kebab-like structures. These MOFs are what break down the CWAs, rendering them harmless.

Sheets like graphene: Tailored chemistry links nanoparticles in stable monolayers
Just like carbon atoms in sheets of graphene, nanoparticles can form stable layers with minimal thicknesses of the diameter of a single nanoparticle. A novel method of linking nanoparticles into such extremely thin films has been developed at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw.

NIST-made 'sun and rain' used to study nanoparticle release from polymers
In a recently published paper, researchers from the National Institute of Standards and Technology (NIST) describe how they subjected a commercial nanoparticle-infused coating to NIST-developed methods for accelerating the effects of weathering from ultraviolet (UV) radiation and simulated washings of rainwater. Their results indicate that humidity and exposure time are contributing factors for nanoparticle release from the coatings, findings that may be useful in designing future studies to determine potential ecological and health impacts.

Uniform 'hairy' nanorods have potential energy, biomedical applications
Materials scientists have developed a new strategy for crafting one-dimensional nanorods from a wide range of precursor materials. Based on a cellulose backbone, the system relies on the growth of block copolymer 'arms' that help create a compartment to serve as a nanometer-scale chemical reactor. The outer blocks of the arms prevent aggregation of the nanorods.

Stealth pig cells may hold the key to treating diabetes in humans
University of Alabama at Birmingham researchers are exploring ways to wrap pig tissue with a protective coating to ultimately fight diabetes in humans. The nano-thin bilayers of protective material are meant to deter or prevent immune rejection. The ultimate goal: transplant insulin-producing cell-clusters from pigs into humans to treat Type 1 diabetes.

UAlberta mechanical engineering in hot pursuit of creeping bacteria
The growth of bacterial biofilm is problematic when you think of all the liquid flowing through all those miles of tubing at your local hospital or Medi-Centre. The movement of bacteria with flow can lead to the spread of infection. Mechanical engineering professor Aloke Kumar's lab set out to study the formation of the filaments, as well as the conditions under which they begin to break down and finally break off.

Breakthrough in materials science: Kiel research team can bond metals with nearly all surfaces
How metals can be used depends particularly on the characteristics of their surfaces. A research team at Kiel University has discovered how they can change the surface properties without affecting the mechanical stability of the metals or changing the metal characteristics themselves. This fundamentally new method is based on using an electrochemical etching process, in which the uppermost layer of a metal is roughened on a micrometer scale in a tightly controlled manner.

Tooth decay -- drilling down to the nanoscale
With one in two Australian children reported to have tooth decay in their permanent teeth by age 12, researchers from the University of Sydney believe they have identified some nanoscale elements that govern the behavior of our teeth. Material and structures engineers worked with dentists and bioengineers to map the exact composition and structure of tooth enamel at the atomic scale.

Researchers design solids that control heat with spinning superatoms
Superatom crystals are periodic arrangements of C60 fullerenes and similarly sized inorganic molecular clusters. There are two nearly identical formations, one with rotating (i.e. orientationally disordered) C60s and low conductivity, and one with fixed C60s and high thermal conductivity. Superatom crystals represent a new class of materials with potential for applications in sustainable energy generation, energy storage, and nanoelectronics. Additional research could lead to controlling rotational disorder in new kinds of thermal switches and transistors.

Location matters in the self-assembly of nanoclusters
Scientists at Iowa State University have developed a new formulation that helps to explain the self-assembly of atoms into nanoclusters and to advance the scientific understanding of related nanotechnologies. Their research offers a theoretical framework to explain the relationship between the distribution of 'capture zones,' the regions that surround the nanoscale 'islands' formed by deposition on surfaces, and the underlying nucleation or formation process.

The potential to develop 'materials that compute' has taken another leap at the University of Pittsburgh's Swanson School of Engineering, where researchers for the first time have demonstrated that the material can be designed to recognize simple patterns. This responsive, hybrid material, powered by its own chemical reactions, could one day be integrated into clothing and used to monitor the human body, or developed as a skin for 'squishy' robots.
