objective: surface coating of dental mirrors using nanotechnology has been done to render them self-cleaning properties. nano-scaled titanium dioxide particles (tio2)show antimicrobial properties when exposed to ultra-violet (uv) light. the aim of this study was to evaluate the effect of surface coating of dental mirrors with nano titanium dioxide on their self-cleaning (from dentists’ perspect...

The properties and oxidation wear patterns in the composite nanostructured coating of Zr-ZrN-(Zr,Mo,Al)N were studied during turning Inconel 718 alloy at cutting speeds vc = 125 200 m/min. hardness coating, its elastic modulus, critical fracture load scratch testing determined. study focused on tribological temperatures 400–900 °C paired with an insert made 718, which exhibited a certain advant...

One of the major complications associated with implantation biomedical devices regardless their function is biomaterial-associated infection. Infections are generally initiated by opportunistic bacterial colonization and biofilm development on surface implanted biomaterials, rendering infection impervious to host defenses antimicrobials. Moreover, around soft tissues also has a significant role...

Abstract The high melting point and strong chemical bonding of NbB 2 pose a great challenge to the preparation high-density nanostructured composite coating. Herein, we report novel, simple, efficient method fabricate in-situ -NbC-Al O 3 coating by plasma spraying Nb 5 -B 4 C-Al powder, aiming at realizing higher densification ultra-fine microstructure properties were studied comparatively with...

Abstract In order to design and fabricate hydrophobic, durable anti-icing coating for aircraft, a polyurethane elastomer matrix was hydrophobically modified incorporated with fluorinated SiO 2 nanoparticles prepare micro/nanostructured coating. The low surface energy displayed significantly improved mechanical properties hydrophobicity, which exhibited the water contact angle of 162° as well sl...

In this work, the effects of strontium addition on the structure and optical properties of nanostructured bismuth silicate (Bi4Si3O12) thin films prepared via sol-gel were studied. At first, different sols containing the optimum ratio of precursors were synthesized, and then, the prepared sols were coated on the substrate via dip coating. The dip coated samples were dried at 100oC and, in order...

The article studies the tribological properties of multicomponent nanostructured coatings Zr-ZrN-(Zr,Cr,Al)N and Zr-ZrN-(Zr,Mo,Al)N, as well wear resistance fracture behaviour cutting tools with mentioned during turning Inconel 718 alloy. Ti–TiN-(Ti,Cr,Al)N coating was also considered a reference coating. While is characterized by high hardness, it demonstrated coefficients friction (COF) at te...

Nanorod-FeP@C composites are synthesized via a one-pot solution reaction of ferrocene (Fe(C5H5)2) with excess triphenylphosphine (PPh3) in sealed vacuum tubes at 390 °C, in which PPh3 is used as both the phosphorus source and solvent in the reaction. The structure and lithium storage performance of the as-prepared nanorod-FeP@C composites are intensively characterized, and it is interesting tha...

Electro-hydrodynamic processing, comprising electrospraying and electrospinning techniques, has emerged as a versatile technology to produce nanostructured fiber-based and particle-based materials. In this work, an antimicrobial active multilayer system comprising a commercial polyhydroxyalkanoate substrate (PHA) and an electrospun PHA coating containing in situ-stabilized silver nanoparticles ...
