Effect of Cu2O Substrate on Photoinduced Hydrophilicity of TiO2 and ZnO Nanocoatings
Nanomaterials, 2021 The effect of a Cu2O substrate on the photoinduced alteration of the hydrophilicity of TiO2 and ZnO surfaces was studied. It was demonstrated that the formation of heterostructures Cu2O/TiO2 and Cu2O/ZnO strongly changed the direction of the photoinduced

Buckling analysis of FML cylindrical shells under combined axial and torsional loading [PDF]
Mechanics of Advanced Composite Structures, 2020 Generally, in-served cylindrical shells buckling usually takes place not merely under one of the basic loads, i.e., axial compression, lateral pressure, and torsion, but under a combination of them.

Nanocomposite Microcontainers [PDF]
Advanced Materials, 2012 Versatile all-nanocomposite capped microcontainers are made using layer-by-layer (LBL) assembly. The microcontainers can act as inert packaging with slow/controlled release for virtually any type of encapsulating material based on clay nanocomposites 3D molded by PDMS templates and capped with another LBL film.

Clay−Fulleropyrrolidine Nanocomposites [PDF]
Journal of the American Chemical Society, 2006 In this work, we describe the insertion of a water-soluble bisadduct fulleropyrrolidine derivative into the interlayer space of three layered smectite clays. The composites were characterized by a combination of powder X-ray diffraction, transmission electron microscopy, X-ray photoemission and FTIR spectroscopies, and laser flash photolysis ...

Effects of Magnetic Field in Creep Behavior of Three-Phase Laminated Composite Cylindrical Shells [PDF]
Mechanics of Advanced Composite Structures, 2019 Due to the importance effect of magnetic field on the history of long-term radial and circumfer-ential creep strain and radial displacement for a three-phase nano-composite exposed to an internal pressure and placed uniform temperature, the present ...
