The Carbon Cycle

Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle. Biological Carbon Cycle All...

Long and hollow glassy carbon microfibers were fabricated based on the pyrolysis of a natural product, human hair. The two fabrication steps of carbon microelectromechanical and carbon nanoelectromechanical systems, or C-MEMS and C-NEMS, are: (i) photolithography of a carbon-rich polymer precursor and (ii) pyrolysis of the patterned polymer precursor.

Source: Laboratories of Margaret Workman and Kimberly Frye - Depaul University Elemental Analysis is a method used to determine elemental composition of a material. In environmental samples such as soils, scientists are particularly interested in the amounts of two ecologically important elements, nitrogen and carbon. Elemental analysis by the flash combustion technique works by oxidizing the sample with a catalyst through combustion in a high-temperature chamber. The products of combustion are...
FAQs
A carbon-containing precursor must deposit on the substrate and bond to its surface to form an effective layer. Controlled heating or plasma-assisted processing can support this formation, while the resulting carbon layer creates a barrier between the material and its environment. That barrier helps determine how the underlying substrate experiences chemical exposure, electrical conditions, mechanical demands, or physiological surroundings.
These design variables determine how the coated surface interacts with its surroundings. Thickness can influence the barrier provided by the layer, while composition and surface structure help regulate chemical, electrical, mechanical, and biological behavior. In bioengineering, adjusting them allows researchers to influence cell interactions and adapt a coating to the performance requirements of a particular electrode, implant, or sensor.
The coating separates the underlying material from its environment, which can improve stability and corrosion resistance when a device operates under physiological conditions. Its carbon-based layer can also support electrical conductivity and biocompatibility, depending on the coating design. These combined effects are important when the substrate must maintain performance while remaining compatible with biological surroundings.
A typical workflow begins by selecting the material that requires surface modification and a suitable carbon-containing precursor. The precursor is then deposited onto the substrate and bonded through controlled heating or plasma-assisted processing. Researchers can subsequently tailor the coating's thickness, composition, and surface structure to achieve the desired chemical, electrical, mechanical, or biological behavior.
Carbon coating can be applied to electrodes, implants, sensors, and other biomedical devices when their surface performance limits stability or function. Depending on its design, the layer may improve conductivity, corrosion resistance, biocompatibility, or environmental protection. These advantages can help extend device performance and support more reliable operation in physiological conditions.
Surface tailoring provides a way to regulate how cells respond to a device rather than treating the coating as a fixed barrier. Researchers can adjust thickness, composition, and surface structure to modify biological behavior at the interface. This is especially relevant for implants and other biomedical devices, where cell interactions and biocompatibility contribute to overall device performance.
