in our current study, supercritical water impregnation (scwi) was introduced as a unique catalyst preparation method by employing the high diffusivity property of supercritical water. the method allows nano-particles to place on support surfaces in extremely dispersed conditions. the silica-based nanocatalyst granules for this purpose were prepared by initial impregnation of highly porous silic...

cazro3 nanoceramics were successfully synthesized at 700 c using the molten salt method, and the effects of processing parameters, such as temperature, holding time, and amount of salt on the crystallization of cazro3 were investigated. cacl2, na2co3, and nano-zro2 were used as starting materials. on heating, cacl2–nacl molten eutectic salt provided a liquid medium for the reaction of caco3 an...

the concept of fuzzy soft γ-ring is introduced; and some properties of fuzzy soft γ-rings are given. then the definitions of fuzzy soft γ-ideals are proposed and some of their theories are considered.

Although DNA nanowires have proven useful as a template for fabricating functional nanomaterials and a platform for genetic analysis, their widespread use is still hindered because of limited control over the size, geometry, and alignment of the nanowires. Here, we document the capillarity-induced folding of an initially wrinkled surface and present an approach to the spontaneous formation of a...

Controlling the shape of surface nanostructures is fundamental for various potential applications examples, in water harvesting systems, liquid transportation or oil/water separation membranes. In this paper, creation porous structures made by a process called templateless electropolymerization, which (H2O) oxidized/reduced to form gas (O2/H2) bubbles onto surfaces and acting as soft template p...

Polymeric nanomaterials are deemed to unlock the potential of therapeutics and improve their efficiency, allow future advances in nanomedicine. Among these, sugar-based nanocapsules made synthetic or natural carbohydrate-based macromolecular chains have raised significant interest bio-applications. This review highlights physical or/and chemical techniques construct both water- oil-filled nanoc...

Here we report the soft-template-assisted electrochemical deposition of mesoporous semiconductors (CdSe and CdTe). The resulting films are stoichiometrically equivalent contain mesopores homogeneously distributed over entire surface. To demonstrate versatility method, two block copolymers with different molecular weights used, yielding pores either 9 or 18?nm diameter. As a proof concept, CdSe ...
