A nanotechnology engineer designs nanoparticles that absorb CO2 at a rate of 0.03 mg/cm²/min. If a filter contains 50,000 cm² of these particles, how many grams of CO2 are absorbed in 2 hours? - Dachbleche24

Understanding the Context

Revolutionizing Carbon Capture with Nanotechnology

As global efforts to combat climate change intensify, innovative technologies are emerging to capture carbon dioxide (CO₂) from the atmosphere at unprecedented efficiency. One such breakthrough comes from nanotechnology engineers who have engineered specialized nanoparticles designed to absorb CO₂ rapidly and selectively. These tiny particles operate at a remarkable rate—up to 0.03 milligrams of CO₂ absorbed per square centimeter per minute.

But how does this translate into real-world impact? Let’s explore a practical example to understand the scale and potential of nanoparticle-based carbon filtration.

The Science Behind the Efficiency

Key Insights

Nanoparticles offer a huge surface area relative to their size, making them highly effective in capturing greenhouse gases. In this scenario, the CO₂ absorption rate of 0.03 mg/cm²/min per particle layer enables filters with remarkable air-cleaning capacity.

Assuming a CO₂-absorbing filter surface area of 50,000 cm², we calculate how much CO₂ can be captured over time.

Step-by-Step Calculation: CO₂ Removed in 2 Hours

1. Convert time to minutes:
   2 hours = 2 × 60 = 120 minutes

Final Thoughts

2. Calculate total absorption per cm² over 2 hours:
   Absorption rate = 0.03 mg/cm²/min
   Total per cm² = 0.03 mg/cm²/min × 120 min = 3.6 mg/cm²

3. Total absorption for 50,000 cm² filter:
   50,000 cm² × 3.6 mg/cm² = 180,000 mg

4. Convert milligrams to grams:
   180,000 mg = 180 grams

Final Result:

A CO₂ absorption filter featuring 50,000 cm² of nanotechnology-engineered particles absorbs exactly 180 grams of CO₂ in just 2 hours.

This advancement demonstrates how precision design at the nanoscale can significantly scale carbon capture solutions—making them viable for industrial applications, urban air purification, and sustainable development goals.
