Study Notes
Shinkansen Bullet Train Design
- The nose of the redesigned Shinkansen bullet train was inspired by the kingfisher bird, known for its aerodynamic shape that reduces air resistance.
- This design innovation allows for smoother entry into tunnels, minimizing the pressure change that can cause noise.
Genetically Modified Corn
- Genes from the bacterium Bacillus thuringiensis (Bt) were used to develop genetically modified corn, enhancing its resistance to certain pests.
- The incorporation of Bt genes helps reduce the need for chemical insecticides, promoting a more sustainable agriculture practice.
Biofiltration Process
- Biofiltration involves the use of living materials, typically microorganisms, to remove or neutralize contaminants from air or water.
- This process is commonly employed in waste treatment and air purification systems, utilizing natural biological processes for cleaning pollutants.
Nanoparticle Size Range
- Nanoparticles typically range from 1 to 100 nanometers in size, falling within the nanoscale category.
- Due to their small size, nanoparticles exhibit unique physical and chemical properties, making them useful in various applications, including medicine and materials science.
Potential of Biofertilizers
- Biofertilizers have the potential to enhance soil fertility and promote plant growth through the introduction of beneficial microorganisms.
- They offer an eco-friendly alternative to chemical fertilizers, contributing to sustainable agriculture by improving nutrient availability and soil health.
