Metal and metal oxide nanomaterials
Intrinsic properties of nanomaterials and morphological charactheristics, which vary according to the selected method of synthesis.
Materials in the form of nanoparticles have a high specific surface in comparison with conventional »bulk« materials, a characteristic that can have a significant impact on their phisical and chemical properties.
This is of increasing importance in the creation of novel and improved materials in differnet field of tehnological applications; from electronics to mechanics, as well as in biomedical and pharmaceutical applications, such as templates for discovery and separations, and in material science applications that range from polymeric nanocoposites and battery elements to fuel cells and catalysis.
An immense effort in Nanotesla Institute Logatec over the last year was to produce a wide spectrum of doped and undopped nonmagnetic nanomaterials of various particle size and morphology.
Nanomaterials made in our Nanolaboratory can be avalible in different forms, such as dry powders, as surface functionalized powders or as dispersions in a variety of solvents, both of aqueous and organic:
- Zinc oxide (ZnO) nanoparticles
- Silicon dioxide (SiO2) nanoparticles
- Colloidal SiO2 dispersion
- SiO2 aerogel
- Titanium dioxide (TiO2) nanoparticles
- Colloidal TiO2 dispersion
- Colloidal silver (Ag/AgO) nanoparticles
- Colloidal Ag/AgO dispersion
- Aluminum oxide (Al2O3) nanoparticles
- Colloidal aluminium trihydroxide (ATH) dispersion
Zinc oxide (ZnO) nanoparticles
Zinc oxide (ZnO) nanoparticles have found imporatnt applications in the production of paints, ceramics, catalysts, electronics (varistors, gas sensors, piezoelectric transducers, optical waveguides) etc. Depends on synthesis method Zinc oxide (ZnO) particles of various particle size (from 10 nm to 1,5 µm) and shapes (spheroids, ellipsoids, hexagons, stars, etc.) can be obtained.
Silicon dioxide (SiO2) nanoparticles
Silica nanoparticles ocuppy a prominent position in scientific research, because of their easy preparation and their wide use in various industrial applications, such as catalysis, pigments, pharmacy, electronic and thin film substrates, electronic and thermal insulators and humidity sensors.
The quality of some of these products is highly dependant on the size and size distribution of these particles.
Titanium dioxide (TiO2) nanoparticles
Titanium dioxide is a versatile material with unique properties which make it ideal for a wide range of applications in electronics snd semiconductor industry, as a pigments for providing whiteness and opacity in paints and coatings, including glazes and enamels in plastics, paper, inks, fibers, food and cosmetics, for anti microbal purposes in medical devices, food preparation surfaces, air conditioning filters, sanitaryware surfaces, water purification and as photocatalyst.
Titanium dioxide in anatase and rutil crystal structure can be prepared in different forms, such as dopped or undopped dry powders, as surface functionalized powders and as dispersions in an aqueous and organic solvents.
Colloidal silver (Ag/AgO) nanoparticles
Silver has a number of unique properties which makes it useful in medical applications for antimicrobial purposes, for water purification, as catalyst, etc.
