Tailoring materials to obtain unique, or significantly enhanced material properties through rationally designed structures rather than chemical constituents is principle of metamaterial concept, which leads to the realization of remarkable optical and mechanical properties. Inspired by the recent progress in electromagnetic and mechanical metamaterials, here we introduce the concept of ferroele...

As socie ty becomes more comfortable discussing genetics and its related ethics, a new technology is blossoming in the background. Nanotechnology may speak the same societal language as does genetics, in that both technological movements involve tiny science and large imagination. In a way, it is natural—and almost inevitable—that the genetic revolution and the nanotechnology revolution be comp...

In this work, we present new results about the non-enzymatic detection of lindane by using CuO-MnO2 hierarchical nano-microstructures. The linear range for the determination of lindane is up to 700 μM with a limit of detection of 4.8 nM, which is much lower than for other non-enzymatic lindane sensors.

A tribochemistry-induced selective etching approach is proposed for the first time to produce silicon nanostructures without lattice damage. With a ~1 nm thick SiOx film as etching mask grown on Si(100) surface (Si(100)/SiOx) by wet-oxidation technique, nano-trenches can be produced through the removal of local SiOx mask by a SiO2 tip in humid air and the post-etching of the exposed Si in potas...

The development, optimization and application of new geopolymer composite materials must necessarily go through a precise accurate physico-chemical mineralogical characterization down to the micro nanoscale. In this regard, SEM-EDS X-ray microanalysis is widely successfully employed by scientific community industry. However, nano-to-micrometre sized architecture many composites introduces diffi...

Plasmonic nanostructures with a negative Poisson ratio are demonstrated, having the unusual mechanical property of auxetics to expand laterally when being stretched. Using nanomembrane technology, auxetics are shrunk by orders of magnitude, giving simultaneous access to optical properties of plasmonic metamaterials, as well as auxetic mechanical properties on the nanoscale.

The aim of this study was to evaluate the effect of desensitizing agents on the bond strength of different adhesive systems condition and rinse and self-etching to dentin through microshear. Sixty dentin fragments were used, obtained from the buccal and lingual surfaces of molars third molars, which were distributed in groups (n = 12) according to desensitizing treatment (control no treatment; ...
