Zinc carbonate is a chemical compound also known as zinc spar, smithsonite or turkey fat. It is an ore of zinc with a chemical formula ZnCO3. It belongs to organic carbonic acids and derivatives family.  Zinc carbonate is a white and odorless crystalline solid, sub-micron or nano-powder which is insoluble in water, alcohol or acetone. Zinc carbonate also exhibits fluorescence when exposed to ultraviolet light, making it an interesting subject for mineral collectors and researchers …

In 1985, three scientists produced a fullerene, named C60, in fewer quantities by vaporizing the graphite in the arc or the laser beam or with an electric current in a low-pressure argon or helium atmosphere. Since then, they have gained significant attention in different fields. The newly found molecule was named by these scientists after Richard Buckminster Fuller, in 1967, he made a dome of shape like the carbon cluster, whereas, in 1970, the possibility of fullerenes existence wa …

Chromium oxide with the formula of Cr2O3 is one of the main oxides of chromium used widely as in pigment production. Chromium oxide occurs as a scarce mineral called Eskolaite crystallized like a hexagonal close-packed set of anionic oxides. Vahid Javan KouzegaranAnalytical Chemist (Ph.D.) / Nanografi Nano Technology IntroductionCr­2O3 is physically a hard brittle metal and remains antiferromagnetic at temperatures as high as 37°C. The main reason behind developing methods to …

Concrete, the second most important material in construction after water, is advantageous however; its low tensile strength requires reinforcement. Nanotubes are found to be promising natural materials for the reinforcement of concrete at nano scales. IntroductionDifferent nanotubes suggested as a natural means for reinforcing concrete are carbon nanotubes, clay nanotubes, and cementitious nanotubes. The importance of concrete in the construction sector is undeniable due to i …

Nanotechnology involves the study, imaging, measuring, modeling, or manipulation of matter at scales falling in the range of 1–100 nanometers (nm). It is a highly multidisciplinary field, drawing from fields such as chemistry, materials science, colloidal science, applied physics, engineering, and biology. IntroductionIn a relatively short span of about 30 years of research, nanotechnology is already having an impact on society and several industrial sectors, and such impact will inc …
