ATT is a global manufacturer of numerous nanoscale materials
ATT is a global manufacturer of numerous nanoscale materials including nanoparticles, nanopowder, nanotubes, nanowire, quantum dots, submicron, -325 mesh, and high surface area metal powders with particle distribution and size controlled and certified. We also produce larger -40 mesh, -100 mesh, -200 mesh range sizes and <0.5 mm, 2 mm, 5 mm and other mm sizes of shot, granules, lump, flake and pieces. Our technical teams are experts in not only the chemical properties of advanced materials, but also their physical properties and morphology.
ATT is capable of producing most compounds, metals, and alloys in the submicron and nanopowder range and atomized metallic powders in sizes as low as -325 mesh to ultrafine particle. Surface areas as high as 140 m2/g have been achieved. We can also produce certain metallic catalytic powders (such as platinum) in the submicron and nanoparticle range.

Green Technology & Alternative Energy
Nanostructured metallic and ceramic particles for vastly improve the performance of solid-state alternative energy sources such as fuel cells and batteries, and researchers are actively investigating novel means of utilizing these materials in electrodes, electrolytes, and catalysts that improve on current technologies.
Silicon nanoparticles have been shown to dramatically expand the storage capacity of lithium ion batteries without degrading the silicon during the expansion-contraction cycle that occurs as power is charged and discharged. Silicon has long been known to have an excellent affinity for storage of positively charged lithium cations, making them ideal candidates for next generation lithium ion batteries. However, the quick degradation of silicon storage units has made them commercially unfeasible for most applications. Silicon nanowires, however, cycle without significant degradation and present the potential for use in batteries with greatly expanded storage times.
Rare earth nanoparticles have become particularly important in the development of both cost-effective solid oxide fuel cells (SOFCs) and hydrogen storage technologies based on metal hydrides, including nickel metal-hydride (NiMH) batteries. Materials such as LSM, strontium carbonate nanoparticles, manganese nanoparticles, Manganese oxide nanoparticles, nickel oxide nanoparticles, and several other nanomaterials are finding application in the development of small cost-effective solid oxide fuel cells (SOFCs). Platinum nanoparticles are being used to develop small proton exchange membrane fuel cells (PEM).
Ultra high purity silicon nanoparticles are being used in new forms of solar energy cells. Thin film deposition of silicon quantum dots on the polycrystalline silicon substrate of a photovoltaic (solar) cell increases voltage output as much as 60% by fluorescing the incoming light prior to capture.
Certain nanomaterials serve as effective products for environmental remediation. For example, nickel nanocrystals are a reagent for the dehalogenation of trichloroethylene (TCE) , a common groundwater contaminant. A team of researchers from Singapore and the United States developed a lightweight, porous gel embedded with silver nanoparticles that effectively kill bacteria in tainted water, leaving it purified and potable.
Coatings
Nanoparticles can be applied directly or as an additive to coatings to produce a number of effects on a given surface such as anti-reflective, hydrophobic, adhesive, or anti-microbial properties. For example, liquid repellant coatings are used for numerous applications such as consumer products, vehicles, textiles and more.
Zinc oxide nanoparticles, zinc nanoparticles and silver nanoparticles are often used as anti-microbial, anti-bacterial, anti-biotic and anti-fungal agents when incorporated in coatings, fibers, polymers, first aid bandages, plastics, soap and textiles.
Industrial Chemistry
For a given amount of material, as particle size decreases, surface area increases. American Elements cerium oxide nanoparticles, platinum nanoparticles, gold nanoparticles, palladium nanoparticles, molybdenum nanoparticles, nickel nanoparticles and iridium nanoparticles have extremely high surface areas which increase their effectiveness as catalysts in a range of chemical synthesis, chemical treatment and petrochemical cracking applications.
Biomedical
The biomedical and bioscience fields have found near limitless uses for nanoparticles. Nanoparticles made of peroxalate ester polymers with a fluorescent dye (pentacene) encapsulated into the polymer have shown to be capable of detecting cancer since hydrogen peroxide is generated by pre-cancerous cells. The dye-bound nanoparticles fluoresce upon coming into contact with hydrogen peroxide which is then detected using medical imaging equipment. When bound to organic molecules, gold and silver nanoparticles have proven to be effective in delivering pharmaceutical drugs to the bodies of cancer patients.
Artificial bone composites are now being manufactured from calcium phosphate nanocrystals. These composites are made of the same mineral as natural bone, yet have strength in compression equal to stainless steel. Tungsten oxide nanoparticles are being used in dental imaging because they are sufficiently radiopaque (impervious to radiation) for high quality X-ray resolution. The group of magnetic nanoparticles discussed above is being used to both kill cancer cells in malignant tumors and in MRI medical imaging. Coating tungsten particles with DNA and injecting them into plant cells or plant embryos allows for the transformation of plant plastids with lower transformation efficiency than in agro bacterial mediated transformation. The anti-bacterial and anti-microbial effects of many nanoparticles such as silver are well understood technology. Fluorescent nanoparticles are being used by biologists to stain and label cellular components. By changing the particle size of quantum dots the specific color emitted can be controlled. With a single light source, one can see the entire range of visible colors, presenting an advantage over traditional organic dyes.
Nanorobotics
Nanorobots are engineered nanoscale mechanical devices or machines that can be used for applications in medicine, environmental remediation, renewable energy, or computing. Most of these applications are in research and development stages with medical applications, also known as nanomedicine, showing particular promise. Medical researchers at Johns Hopkins University have studied the uses of nanobots for drug delivery, diagnostics and surgical procedures. Another application of nanobots is in developing nanoscale molecular positions systems or conveyor belt-like systems using nanoscale molecules that act like motors when attached to macroscopic surfaces.
Metamaterials
Nanotechnology is a powerful tool in the fabrication of metamaterials: artificial materials designed to exhibit properties not previously found in nature. The potential to tune materials with precise properties for different applications can have a profound impact on nearly every industry.
