Bioinspired process makes materials light, robust, programmable at nano- to macro-scale
A new bioinspired process combines top-down and bottom-up assembly to turn silk protein into materials that are easily programmable at the nano-, micro- and macro-scales; ultralight; and robust. Structures made included a web of silk nano fibers able to sustain a load 4,000 times its own weight.

A new dimension in chemical nanoimaging
Researchers from the Basque institutions CIC nanoGUNE, Ikerbasque and Cidetec, and the German Robert Koch-Institut report the development of hyperspectral infrared nanoimaging. It is based on Fourier transform infrared nanospectroscopy (nano-FTIR) and enables highly sensitive spectroscopic imaging of chemical composition with nanoscale spatial resolution.

Researchers pave the way for ionotronic nanodevices
Ionotronic devices rely on charge effects based on ions, instead of electrons or in addition to electrons. These devices open new opportunities for creating electrically switchable memories. Researchers at Aalto University in Finland have visualized how oxygen ion migration in a complex oxide material causes the material to alter its crystal structure in a uniform and reversible fashion, prompting large modulations of electrical resistance. Resistance-switching random access memories could utilize this effect.

Light-driven reaction converts carbon dioxide into fuel
Duke University researchers have developed tiny nanoparticles that help convert carbon dioxide into methane using only ultraviolet light as an energy source. Having found a catalyst that can do this important chemistry using ultraviolet light, the team now hopes to develop a version that would run on natural sunlight, a potential boon to alternative energy.

Researchers use laser-generated bubbles to create 3-D images in liquid
Researchers have developed a completely new type of display that creates 3-D images by using a laser to form tiny bubbles inside a liquid 'screen.' Instead of rendering a 3-D scene on a flat surface, the display itself is three-dimensional, a property known as volumetric. This allows viewers to see a 3-D image in the columnar display from all angles without any 3-D glasses or headsets.

Atom-scale oxidation mechanism of nanoparticles helps develop anti-corrosion materials
The research group led by Prof. BAO Xinhe from Dalian Institute of Chemical Physics, Chinese Academy of Sciences discovered that oxide nanostructures (NSs) with a diameter below 3 nm could exhibit an oxidation resistance much more superior than larger NSs. By investigating the oxidation mechanism at the atomic level, the team proposed, for the first time, a "dynamic size effect", that determines the stability of supported nanoparticles.

In mid-February 2017 researchers of Peter the Great St. Petersburg Polytechnic University (SPbPU) and the University of Madras obtained support of the Russian Foundation for Basic Research for implementation of the project to create new materials for accumulators of capacitor type. The project should be completed within three years.

Nanotechnology and nanopore sequencing
DNA is the hereditary material in our cells and contains the instructions for them to live, behave, grow, and develop. These instructions are based on the order of the DNA bases, called nucleotides. To unlock the instructions, carried by a DNA molecule, we need to read these nucleotide sequences (by performing DNA sequencing).

Microhotplates for a smart gas sensor
Toyohashi University of Technology researchers have developed microhotplates (MHPs), in which an SU-8 photoresist was employed as a supporting material. The MHP can moderate the requirement for the layout design and the process condition of integrated smart gas sensors. Furthermore, the researchers confirmed that the MHP has a good thermal isolation property. It was demonstrated that the hotplate can be heated to 550 °C, and that it operates stably for 100 min.

Scientists create a nano-trampoline to probe quantum behavior
For the first time, scientists have measured quantum criticality by developing a thin membrane suspended in air by very narrow bridges, thereby forming a 'nano-trampoline'. This enabled specific heat measurements of thin films through a quantum phase transition from a superconducting state to an electrically insulating state close to absolute zero temperature, and is expected to be a milestone in the understanding of physical processes that govern the behavior of ultrathin systems at ultralow temperatures.

Improved polymer and new assembly method for ultra-conformable 'electronic tattoo' devices
Waseda University researchers developed processes and materials for ultrathin devices using SBS elastomeric film, achieving ease of production, high elasticity and flexibility fifty times better than previously reported polymer nanosheets. Production of circuits with a household type inkjet printer, without the need for clean room conditions, along with fixing of electronic components without soldering promise to greatly increase wearing comfort and to radically lower barriers to manufacturing.

New window into the nanoworld
For the first time ever, scientists have captured images of terahertz electron dynamics of a semiconductor surface on the atomic scale. The successful experiment indicates a bright future for the new and quickly growing sub-field called terahertz scanning tunneling microscopy (THz-STM), pioneered by the University of Alberta in Canada. THz-STM allows researchers to image electron behaviour at extremely fast timescales and explore how that behaviour changes between different atoms.

A novel positioning algorithm based on self-adaptive algorithm
Much attention has been paid to the Taylor series expansion (TSE) method these years, which has been extensively used for solving nonlinear equations for its good robustness and accuracy of positioning. An early Taylor-series expansion location algorithm based on the RBF neural network (RBF-TSE) is proposed as the performance of TSE highly depends on the initial estimation.

Switched-on DNA
DNA, the stuff of life, may very well also pack quite the jolt for engineers trying to advance the development of tiny, low-cost electronic devices. Much like flipping your light switch at home -- only on a scale 1,000 times smaller than a human hair -- an ASU-led team has now developed the first controllable DNA switch to regulate the flow of electricity within a single, atomic-sized molecule.

Future trends for top materials by Mario J F Calvete
In the last four decades materials science has evolved and developed into a very diverse range of highly specialized family of compounds -- from what were once essentially esoteric, often topical, basic research specialties -- into what one would clearly class today as one of the most significant and important industrial fields and specializations of our modern era.
