The influence its quantitative composition the physical and mechanical properties fine-grained concrete studied. results study frost resistance enriched with CNM "Taunit" are presented.The main hypotheses describing formation porous structure under action alternate freezing thawing con...

Natural composites have gained importance recently due to increasing environmental factors and relatively low cost. Although their biodegradability, density, high processability, the use of natural fibers in composite materials as only reinforcement phase faces with some challenges disadvantages such moisture absorption mechanical properties. To overcome these issues, are generally utilized by ...

Natural-based composite’s progress as carriers has revealed many benefits in biomedicine, notably the construction field, synthetic biology, and genetic engineering. Compared to analogous composites without nanoparticles, incorporating nanoparticles into polymeric materials improved architectural performance, physiological connections, ecological features. The major goal of current investigatio...

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.

Seawater can be used as mixing water for concrete with no steel reinforcement in some areas difficult access to fresh water. Diatoms such Phaeodactylum tricornutum are among the most abundant micro-organisms living seawater, and they could unavoidable when collecting seawater. In fact, diatoms provide bio-SiO2 bio-CaCO3 sources, namely amorphous nano-SiO2 crystallised nano-CaCO3, which benefici...

Rapid controlled self-assembly makes DNA ideal for building nanostructures. A problem using hybridized intermediates in hierarchic assembly is their thermodynamic lability. We demonstrate a click-fixation technology by which robust hexagonal DNA modules can be made. This principle is applicable to a wide variety of DNA nanoconstructs.
