CÔNG NGHỆ NANO

🔬 What is Nanotechnology?

1. Basic Concept

• Nano comes from the Greek word nanos, meaning “extremely small.”

• In science, one nanometer (nm) equals one billionth of a meter (10⁻⁹ m).

• Nanotechnology is the study, design, and application of materials, structures, and devices at the 1–100 nm scale.

👉 At this scale, matter exhibits unique properties due to the quantum effect, very different from its bulk form.

2. Key Characteristics of Nanomaterials

1. Large surface area:

   • Nanoparticles have an enormous surface-to-volume ratio.

   • This increases reactivity, energy transfer, and catalytic efficiency.

2. Quantum effects:

   • Electrons are confined in extremely small spaces, leading to quantized energy levels.

   • This alters optical (light absorption/emission), electrical, thermal, and magnetic properties.

3. Enhanced durability & stability:

   • Nanomaterials often have higher heat resistance, corrosion resistance, and longer lifespan.

3. Wide-Ranging Applications of Nanotechnology

• Electronics & IT: microchips, processors, high-speed sensors.

• Energy: solar cells, fuel cells, energy-saving materials.

• Healthcare: targeted drug delivery, FIR-based therapy devices.

• Environment: nano-filtration for clean water and air, emission reduction.

• Transportation: fuel optimization, reduced emissions, extended engine life.

4. Nano Semiconductors – A Breakthrough Frontier

Among all applications, nano semiconductors represent one of the greatest breakthroughs of the 21st century:

• Semiconductor materials (silicon, germanium, alumina) at the nano scale can emit electromagnetic energy when activated by heat, electricity, or magnetism.

• Remarkably, they can release far-infrared rays (FIR, 8–14 μm) – often called “biological light,” because it naturally resonates with the human body.

5. Taiwan’s Nano Semiconductor Innovation

• A Taiwanese professor succeeded in creating advanced nano semiconductors with particle sizes of 18–25 nm, capable of stable and powerful FIR emission.

• Applications in internal combustion engines:

  • Breaks down fuel molecules → ensures complete combustion.

  • Reduces CO, HC, and smoke emissions nearly to zero.

  • Saves 10–20% fuel, while making engines smoother and longer-lasting.

• Applications for the human body:

  • FIR is completely safe, matching the body’s natural wavelength.

  • Health benefits: improves blood circulation, relieves stress, accelerates cell recovery.

🎯 Conclusion

• Nanotechnology harnesses the hidden power of the microscopic world to create superior properties.

• Nano semiconductors combine semiconductor science and nanotechnology, producing FIR energy that benefits both engines and human health.

• Taiwan stands as a global pioneer, delivering high-quality nano semiconductor technology that is widely applied and exported to advanced nations worldwide.
