Biomass derived mesoporous carbon monoliths via an evaporation-induced self-assembly [PDF]

open access: yes, 2013
Evaporation-induced self-assembly has been applied in the synthesis of crack-free mesoporous carbon monolith with good mechanical stability using a waste plant material as carbon precursor and triblock copolymer F127 as template.

No way out? The double-bind in seeking global prosperity alongside mitigated climate change [PDF]

open access: yes, 2012
In a prior study, I introduced a simple economic growth model designed to be consistent with general thermodynamic laws. Unlike traditional economic models, civilization is viewed only as a well-mixed global whole with no distinction made between ...

Hydrothermal Carbonization of Organic Waste and Biomass: A Review on Process, Reactor, and Plant Modeling

open access: yesWaste and Biomass Valorization, 2020
Hydrothermal carbonization (HTC) is an emerging path to give a new life to organic waste and residual biomass. Fulfilling the principles of the circular economy, through HTC “unpleasant” organics can be transformed into useful materials and possibly ...

Rapid pyrolysis of low rank coal: dynamic modeling and parameter analysis of a novel solid heat carrier in a co-current downer reactor

open access: yesCase Studies in Thermal Engineering
A novel co-current downer pyrolyzer was developed to enable high-temperature heat-carrying particles, preheated in a fluidized bed, to directly contact coal particles.

Simulating the Initial Stage of Phenolic Resin Carbonization via the ReaxFF Reactive Force Field [PDF]

open access: yes, 2009
Pyrolysis of phenolic resins leads to carbon formation. Simulating this resin-to-carbon process atomistically is a daunting task. In this paper, we attempt to model the initial stage of this process by using the ReaxFF reactive force field, which bridges
