The design of nanoparticles desired sizes and shapes 2D nanostructured materials is challenging important due to their unique physical chemical properties. One the most common methods for generation metal wet synthetic route in which ions are reduced formed particles stabilized liquid phase. Here we show a facile powerful method synthesize gold solid agarose gel utilizing diffusion reagents usi...

Introduction and Background: Ceramics are inorganic, nonmetallic materials, such as alumina, beryllia, or glassceramic, whose final characteristics are produced by subjection to high temperatures. Nanomaterials is a rapidly growing area of ceramics [1-3] and can be classified into the following categories: Nano-particles submicron or ultra micron size particles; Nano-fibers – nanometer (nm) siz...

the level of dental and oral hygiene on elementary school age children is very low, so it can be increasing the incidence of dental and oral diseases which caused by various microorganisms. moutwash can keep dental and oral hygiene, but many commercial mouthwash is still used alcohol as their ingredients, which can be giving side effects, therefore, we still needed used alternative mouthwash, w...

objective: curcumin is extracted from curcuma longa and regulates the intracellular signal pathways which control the growth of cancerous cell, inflammation, invasion and apoptosis. curcumin molecules have special intrinsic features that can target the intracellular enzymes, genome (dna) and messengers (rna). a wide range of studies have been conducted on the physicochemical traits and pharmaco...

• good electrical conductivity (>100 S cm 1 bulk conductivity), • high thermal conductivity (>20 W cm ), • high chemical and corrosion resistance, • mechanical stability toward compression forces, • low permeability for hydrogen, • low-cost material being processable with mass production techniques, • low weight and volume, and • recyclable materials. Two different kinds of materials have been ...

A typical MCP consists of about 10,000,000 closely packed channels of common diameter which are formed by drawing, etching, or firing in hydrogen, a lead glass matrix. Typically, the diameter of each channel is ~ 10 microns. Each channel acts as an independent, continuous dinode photomultiplier. In astronomy, and in the many other fields that use MCPs, the detectors are generally used for disto...

Bionanotechnology is a combination of three terms: “bios” meaning “life,” “nano” (origin in Greek) meaning “dwarf,” and “technologia” (origin in Greek—comprised of “techne” meaning “craft,” and “logia” meaning “saying”), which is a broad term dealing with the use and knowledge of humanity’s tools and crafts. Biomolecular Nanotechnology—or Bionanotechnology—is a term coined for the area of study...

Bulk quantities of polypyrrole nanofibers and nanospheres can be synthesized with a facile, one-step "green-nano" chemical oxidative polymerization approach, by simply using different reaction media.
