Carbon Nanoparticles

In keeping with our Mission Statement, one of our core activities is to apply nanotechnology and our proprietary nano-carbon materials (nanodiamonds, nano-onions and fullerenes) to develop products for a sustainable economy. Nanotechnology makes it possible to reduce the carbon footprint and environmental impact of existing products and develop altogether new-to-the-world products that provide a number of benefits:

  • Energy: Energy consumption is the most important factor in determining a product’s lifecycle carbon footprint. We are developing products to enhance the energy efficiency of systems by reducing friction, improving heat transfer and improving energy efficiency (i.e. photovoltaic panels).
    Material Replacement: Industrial and consumer products are made of materials whose production can have a negative impact on the environment. We are developing solutions that will allow replacement of hazardous substances in formulated products (e.g. lubricants), or hazardous metals used as quantum dots, and develop new materials with superior mechanical and thermal properties like polymer matrix composites.
  • Lightweighting: Nanotechnology also enables us to use fewer resources including less energy during manufacturing and less fuel for transportation. For instance, our advanced composites with high strength-to-weight ratio enable emission reduction in the transportation industry.
  • Lifetime: Nanotechnology has the potential to significant effect the lifetime of industrial and consumer products, thereby reducing total resource consumption (i.e. need for replacement). Nanoplazz offers enhanced wear and fatigue resistance through its advanced composites.
Nanodiamonds are carbon nanoparticles with a diameter less than 100 nm. Nanodiamonds have a diamond core but the carbon atoms at the surface of the particles are able to form bonds with heteroatoms or organic functional groups affecting stability and performance. Nanodiamonds have a remarkable combination of properties including

  • Extreme hardness
  • Wear resistance
  • High thermal conductivity
  • High electrical resistivity
  • Low thermal expansion
  • Wide band gap
  • High refractive index
  • Low specific gravity
  • Chemical/radiation resistance
  • Biocompatibility
  • Non-cytotoxicity
  • Large surface area
  • High & controllable chemical activity of the surface

Nanodiamonds and other carbon nanoparticles can be incorporated into other bulk materials and formulated products. Because of their unique properties, they can have a significant impact on bulk properties allowing for superior performance or multiple functionalities.

A handful of nanodiamond applications have been commercialized since the discovery of nanodiamonds including

  • Fine polishing abrasives
  • Additives to polymeric coating
  • Additives to electroplating solution
  • Lubricant additives (oils and grease)
  • Additives to polymer matrix composites

In recent years development of applications utilizing nanodiamonds has exploded. Applications attracting significant efforts include

  • Personal care products (skin creams/sunblocks)
  • Theranostics: Drug delivery and Bioimaging
  • Precursors for CVD diamond coatings
  • Catalyst supports
  • Anti-wear and hardening additives for plastics and rubbers
  • Radiation resistant nanocomposites
  • Coolants for dicing wafers
  • Solar cell coatings
  • UV-resistant coatings
  • Glass/polymer scratch protection
  • Electrode modifiers
  • Chromatographic carriers
  • Thermally conductive compounds and nanofluids
  • Supercapacitors

Nanoplazz’s focus on a sustainable economy has defined our early product development efforts:

  1. Advanced lubricants and nanofluids to reduce friction and wear, improve heat transfer, and increase lifetime
  2. Specialty coatings including including coatings for smart optical monitoring.
  3. Novel polymer matrix composites with enhanced strength-to-weight ratios, thermal characteristics, and lifetimes,
  4. Renewable energy applications such as in solar panels and super capacitors
  5. Optical sensors
