The Calvin Cycle01:40

The Calvin Cycle

65.0K
OverviewOxygenic photosynthesis plays a central role in the global carbon and oxygen cycles. The carbohydrates produced support nearly all food webs, while the oxygen by‑product enables aerobic life.Light‑dependent and light‑independent reactionsPhotosynthesis occurs in two main stages, each in a different part of the chloroplast: light‑dependent reactions and light‑independent reactions, also called the Calvin‑Benson cycle or simply the Calvin...

Carbon Dioxide Transport in the Blood01:19

Carbon Dioxide Transport in the Blood

6.9K
Carbon dioxide (CO2) transport in the blood is critical to human physiology. On average, our body cells produce around 200 mL of CO2 per minute, precisely the quantity expelled by the lungs. This process involves the transportation of CO2 from the tissue cells to the lungs in three primary forms.
Forms of CO2 Transport
1. Dissolved in plasma: A small percentage (7-10%) of CO2 is transported and dissolved directly in the plasma.
2. Carbaminohemoglobin: Just over 20% of CO2 is chemically bound to...

Summary

Researchers created nitrogen-containing carbon (NCC) tubes from cotton fibers coated with polypyrrole (PPy). NIR laser or sunlight converted the PPy sheath into NCC, forming hollow tubes with controlled diameters and thicknesses.

Area of Science:

  • Materials Science
  • Nanotechnology
  • Polymer Chemistry

Background:

  • Polypyrrole (PPy) is a conductive polymer with photothermal properties.
  • Nitrogen-containing carbon (NCC) materials have diverse applications due to their unique properties.
  • Developing efficient methods for synthesizing NCC materials is crucial.

Purpose of the Study:

  • To synthesize nitrogen-containing carbon (NCC) tubes using a novel photothermal conversion method.
  • To explore the use of cotton/polypyrrole (PPy) fibers as precursors for NCC tube fabrication.
  • To investigate the influence of light sources and PPy sheath thickness on NCC tube characteristics.

Main Methods:

  • Cotton-core/polypyrrole (PPy)-sheath fibers were synthesized via aqueous chemical oxidative seeded polymerization.
  • Near-infrared (NIR) laser irradiation or sunlight was used for photothermal conversion, decomposing the cotton core and converting the PPy sheath into NCC.
  • Scanning electron microscopy (SEM), elemental microanalysis, Fourier transform infrared spectroscopy (FTIR), and Raman spectroscopy were employed for characterization.

Main Results:

  • Formation of hollow tubes with monodispersed diameters was observed.
  • The PPy sheath was successfully converted into nitrogen-containing carbon (NCC).
  • Tube thickness was tunable from 410 nm to 2.30 μm by adjusting the PPy sheath thickness.
  • The method demonstrated applicability to other polymer fibers like acrylic and wool.

Conclusions:

  • A facile and scalable method for producing NCC tubes from polymer/PPy fibers was established.
  • Photothermal conversion using NIR laser or sunlight offers an effective route for NCC synthesis.
  • The morphology of the resulting NCC tubes closely mimics the precursor polymer/PPy fibers.
