TLDR
In this paper, the authors present a framework to lay out the need for carbon dioxide utilization, the opportunities, boundary conditions, potential pitfalls, and critical needs to advance the required technologies in the time needed.Abstract:
This introduction to the Faraday Discussion on carbon dioxide utilization (CDU) provides a framework to lay out the need for CDU, the opportunities, boundary conditions, potential pitfalls, and critical needs to advance the required technologies in the time needed. CDU as a mainstream climate-relevant solution is gaining rapid traction as measured by the increase in the number of related publications, the investment activity, and the political action taken in various countries.read more

Early age impacts of CO2 activation on the tricalcium silicate and cement systems
TL;DR: The early-age impacts of CO 2 activation (using a dose of 0.3% CO 2 by weight of cement) on two binder systems (tricalcium silicate and cement) were studied, principally across the first 3 h of hydration as discussed by the authors .

Stabilization Wedges: Solving the Climate Problem for the Next 50 Years with Current Technologies
TL;DR: A portfolio of technologies now exists to meet the world's energy needs over the next 50 years and limit atmospheric CO 2 to a trajectory that avoids a doubling of the preindustrial concentration as mentioned in this paper.
Journal ArticleDOI
Supplementary cementitious materials
TL;DR: The use of silica-rich SCMs influences the amount and kind of hydrates formed and thus the volume, the porosity and finally the durability of these materials.

Solar Fuels via Artificial Photosynthesis
TL;DR: Although attempts at artificial photosynthesis fall short of the efficiencies necessary for practical application, they illustrate that solar fuel production inspired by natural photosynthesis is achievable in the laboratory.
