The novel method of the semiconductor nanostructuring (TINE&MEMO) has been developed on the base of the simultaneous AFM-tip induced local anodic oxidation and mechanical modification of the surface under the applying of advanced electric potentials. The TINE&MEMO-based technology allows obtaining the principle new scale of the depth up to 100 nm for the nanostructure fabrication with a low asp...

Biocompatibility and biomechanical stability are two of the main obstacles limiting the effectiveness of vascular scaffolds. To improve the biomechanical stability and biocompatibility of these scaffolds, we created a heparin-nanomodified acellular bovine jugular vein scaffold by alternating linkage of heparin and dihydroxy-iron via self-assembly. Features of the scaffold were evaluated in vitr...

Non destructive, real-time monitoring of the stress/strain state of polymer composites can be achieved through a “nanomodification” of the matrix. Due to their high Raman scattering, electrical conductivity and implicit sensitivity to pressure and temperature, single-walled carbon nanotubes (SWCNT) are ideal elements to fulfil this task. In this work, SWCNT at a loading fraction as low as 0.1 w...

AIM To analyse the physicochemical properties of a Nano white mineral trioxide aggregate (NWMTA) and compare it with white mineral trioxide aggregate (WMTA). METHODOLOGY White mineral trioxide aggregate and NWMTA were prepared and mixed according to the manufacturer's instructions. Surface area of powder before hydration, setting time, X-ray diffraction and microhardness at pH values of 4.4 a...

Reducing the consumption of cement with simultaneous utilizing waste materials as cement replacement is preferred for reasons of environmental protection. Blended cements consist of different supplementary cementitious materials (SCMs), such as fly ash, silica fume, Ground Granulated Blast Furnace Slag (GGBFS), natural pozzolans, etc. These materials should be chemically activated to show effec...

This work investigated how the structure size affects quasi-static and fatigue behaviors of graphene polymer nanocomposites, a topic that has been often overlooked. The results showed both failure these materials scale nonlinearly with due to presence significant fracture process zone (FPZ) ahead crack tip induced by nanomodification. Such complicated effect scaling in either or scenario cannot...

The material removal mechanism, submicrostructure of surface and subsurface layers, nanotransformations occurred in layers during electrical discharge machining two structural materials such as anti-corrosion X10CrNiTi18-10 (12kH18N10T) steel austenite class 2024 (D16) duralumin a deionized water medium were researched. was conducted using brass tool 0.25 mm diameter. measured gap is 45–60 µm f...

The utilization of aquaculture waste, such as snail shells, is a severe issue. These shells are common in water-sources and by-product sifting sand for masonry concrete work. Calcium-rich river great interest cement building materials. In this regard, the purpose article was to develop nanomodified with improved characteristics based on powder shells. Experimental studies have confirmed effecti...
