Slowing Climate Change and Ocean Acidification by Converting Atmospheric Carbon Dioxide to Graphite (CD2G) [PDF]

open access: yesarXiv
Removing carbon dioxide from the atmosphere may slow climate change and ocean acidification. My approach converts atmospheric carbon dioxide into graphite (CD2G). The net profit for this conversion is ~$381/ton CO2 removed from the atmosphere. At the gigaton scale, CD2G factories will increase the affordability and availability of graphite.

Self‐Assembled Hollow Gyroids with Bicontinuous Mesostructures: A Highly Robust Electrocatalyst Fixation Platform

open access: yesAdvanced Materials, EarlyView.
The hollow gyroid carbon (HGC), synthesized via the self‐assembly of block copolymers and vapor pressure‐induced hollow structuring, provides a robust platform for embedding Pt nanoparticles. The HGC morphology facilitates efficient mass transport while the pyridine N inherent in the block copolymer enhances electrical conductivity and electrochemical ...

Internal Validity of Estimating the Carbon Kuznets Curve by Controlling for Energy Use [PDF]

open access: yes
The carbon Kuznetz curve (CKC) hypothesis assumes that carbon dioxide emissions initially increase in tandem with output but start decreasing at higher levels of output.

Metabolic rate meter and method [PDF]

open access: yes, 1968
A method is described for measuring the dynamic metabolic rate of a human or animal. The ratio of the exhaled carbon dioxide to a known amount of C(13)02 introduced into the exhalation is determined by mass spectrometry.
