  • Solar Cells arrow_upward

  • Nanotechnology enhancements provide:
  • Improved Efficiency:
  • Novel nanomaterial’s can harness more of the sun’s energy.
  • Lower Costs:
  • Some novel nanomaterial’s can be made cheaper than alternatives.
  • Flexibility:
  • Thin film flexible polymers can be manipulated to generate electricity from the sun’s energy.

  • Computing arrow_upward

    Faster processing speeds:
  • Miniaturization allows more transistors to be packed on a computer chip.
  • More memory:
  • Nano sized features on memory chips allow more information to be stored.
  • Thermal management solutions for electronics:
  • Novel carbon-based nano materials carry away heat generated by sensitive electronics.

  • Clothing arrow_upward

    Anti-odor properties:
  • Silver nanoparticles embedded in textiles kill odor causing bacteria.
  • Stain-resistance:
  • Nano fiber coatings on textiles stop liquids from penetrating.
  • UV protection:
  • Titanium nanoparticles embedded in textiles inhibit UV rays from penetrating through fabric.

  • Batteries arrow_upward

  • Higher energy storage capacity and quicker recharge:
    • Nanoparticles or nanotubes on electrodes provide high surface area and allow more current to flow.
    Longer life:
  • Nanoparticles on electrodes prevent electrolytes from degrading so batteries can be recharged over and over.
  • A safer alternative:
  • Novel nano-enhanced electrodes can be less flammable, costly and toxic than conventional electrodes.

  • Sporting Goods and Equipment arrow_upward

    Increased strength of materials:
  • Novel carbon nano fiber or nanotube based nano composites give the player a stronger swing.
  • Lighter weight materials:
  • Nano composites are typically lighter weight than their macro scale counterparts.
  • More perfect fabrication of materials:
  • Controlling material characteristics at the nano scale helps ensure that a ball flies in the direction of applied force and/ or reduces the chance for fracture of equipment.

  • Cars arrow_upward

    Increased strength of materials:
  • Novel carbon nano fiber or nanotube nano composites are used in car bumpers, cargo liners and as step-assists for vans.
  • Lighter weight materials:
  • Light weight nano composites mean less fuel is used to make the car go.
  • Control of surface characteristics:
  • Nano scale thin films can be applied for optical control of glass, water repellency of windshields and to repair of nicks/ scratches.

  • Food and Beverage arrow_upward

  • Better, more environmentally friendly adhesives for fast food containers.
  • Anti-bacterial properties:
  • Nano silver coatings on kitchen tools and counter-tops kill bacteria/ microbes.
  • Improved barrier properties for carbona
    -ted beverages or packaged foods:
  • Nano composites slow down the flow of gas or water vapor across the container, increasing shelf life.

  • Environment arrow_upward

    Improved ability to capture groundwater contaminants:
  • Nanoparticles with high surface area are injected into groundwater to bond with contaminants.
  • Replacements for toxic materials:
  • Novel nanomaterial can be engineered to exhibit specific properties that mimic other less desirable materials.

  • Future Applications of Nanotechnology arrow_upward

  • Body armor
  • Drug delivery
  • Cancer
  • Molecular manufacturing
  • Sensors
  • Next generation computing (Quantum, DNA, Molecular)
  • Nanorobotics

  • Body Armor  arrow_upward

  • Nanotechnology enhancements will provide:
  • Stronger materials for better protection:
  • Nano composites that provide unparalleled strength and impact resistance.
  • Flexible materials for more form-fitting  wearability:
  • Nanoparticles-based materials that act like “liquid armor”.
  • Lighter weight materials:
  • Nano materials typically weigh less than their macro-scale counterparts.
  • Dynamic control:
  • Nano fibers that can be flexed as necessary to provide CPR to soldiers or stiffen to furnish additional.

  • Drug Delivery arrow_upward

    New vehicles for delivery:
  • Nanoparticles such as bulky balls or other cage-like structures that carry drugs throughout the body
  • Targeted delivery:
  • Nano vehicles that deliver drugs to specific locations in the body.
  • Time release:
  • Nano structured material that store medicine in nano sized pockets that release small amounts of drugs over time.

  • Cancer  arrow_upward

    Earlier detection:
  • Specialized nanoparticles that target cancer cells only: these nanoparticles can be easily imaged to find small tumors.
  • Improved treatments:
  • Infrared light that shines on the body is absorbed by the specialized nanoparticles in the cancer cells only, leading to an increased localized temperature that selectively kills the cancer cells.

  • Sensors arrow_upward

    Higher sensitivity:
  • High surface area of nano structures that allows for easier detection of chemicals, biological toxins, radiation disease etc.
  • Miniaturization:
  • Nano scale fabrication methods that can be used to make small sensors that can be hidden and integrated into various objects.
