TL;DR: In this paper, a wide variety of biomass substrates, including pure sugars containing five-and six-membered rings with furanose and pyranose configurations, lignin, agricultural residues (corncob and nut shells), and a hard wood, were subject to proximate and elemental analysis, gas sorption analysis, and analysis by inductively coupled plasma mass spectroscopy (ICP-MS), scanning electron microscopy (SEM), X-ray diffraction (XRD), electron spin resonance (ESR), 13C cross-polarization

TL;DR: In this paper, the tradeoff between CO 2 emissions and total cost of technologies is analyzed so that the most cost-effective technology can be determined for different CO2 emissions constraints. And the position of supercritical water gasification in various technologies of energy conversion is examined by modeling an overall energy system.

TL;DR: In this article, a conceptual framework is proposed to reach the sustainable development in a community which is strengthened through the implementation of appropriate technology in order to reach empowerment, concluding that empowerment is the next shape of sustainable development.

TL;DR: In this article, the performance and/or CO 2 intensities of a Bio-DME (Biomass Di-methyl Ether) production system, considering the differences of biomass feedstock, were analyzed.

TL;DR: In this article, the authors describe the performance of an aqueous-alkaline biocarbon fuel cell that generates power at temperatures of ∼500 K. This was achieved using a 6 M KO.
