Direct Methanation and Storage Concepts for the Flexibilization of Biogas Plants

Chemical Engineering &Technology, Volume 46, Issue 3, Page 579-586, March 2023., 2023
Enrichment of the methane fraction in a biogas mixture is a possibility, though challenging, to optimize the existing biogas plants by using excess power. The methanation process and the consequent heat release are studied in a laboratory biogas plant with an innovative heat pipe injector system for cooling the enriched biogas and remixing the biomass ...

Net‐mineralization of organic matter and greenhouse gas emissions from Quebracho tannin‐enriched manure applied to acidic and alkaline soils

Journal of Plant Nutrition and Soil Science, Volume 184, Issue 5, Page 530-542, October 2021., 2021
Abstract Background Mitigation strategies to reduce greenhouse gas emissions, ammonia volatilization, and nitrate leaching from agriculture are important for the management of environmental pollution and climate change. Tannins, which are water‐soluble polyphenolic compounds, were found to reduce emissions in animal husbandry systems when supplemented ...

Aspects of topology of condensates and knotted solitons in condensed matter systems [PDF]

, 1992
The knotted solitons introduced by Faddeev and Niemi is presently a subject of great interest in particle and mathematical physics. In this paper we give a condensed matter interpretation of the recent results of Faddeev and Niemi.Comment: v2: Added a ...

What can gauge-gravity duality teach us about condensed matter physics? [PDF]

, 2012
I discuss the impact of gauge-gravity duality on our understanding of two classes of systems: conformal quantum matter and compressible quantum matter.

Climate change drives habitat contraction of a nocturnal arboreal marsupial at its physiological limits

Ecosphere, Volume 11, Issue 10, October 2020., 2020
Abstract Increasing impacts of climatic change and anthropogenic disturbances on natural ecosystems are leading to population declines or extinctions of many species worldwide. In Australia, recent climatic change has caused population declines in some native fauna.

Zoo of quantum-topological phases of matter [PDF]

, 2017
What are topological phases of matter? First, they are phases of matter at zero temperature. Second, they have a non-zero energy gap for the excitations above the ground state. Third, they are disordered liquids that seem have no feature.

High Temperature Co‐Electrolysis as a Key Technology for CO2 Emission Mitigation – A Model‐Based Assessment of CDA and CCU

Chemie Ingenieur Technik, Volume 92, Issue 8, Page 1044-1058, August 2020., 2020
The application of SOEL technology in CCU and CDA approaches is studied via process modeling. The results of this study highlight the advantages especially of high temperature co‐electrolysis for the purpose of CO2 emission mitigation in industrial applications like steelmaking as well as lime and cement production.

Ranking Influential Nodes in Complex Networks with Information Entropy Method

Complexity, Volume 2020, Issue 1, 2020., 2020
The ranking of influential nodes in networks is of great significance. Influential nodes play an enormous role during the evolution process of information dissemination, viral marketing, and public opinion control. The sorting method of multiple attributes is an effective way to identify the influential nodes.

From Trapped Atoms to Liberated Quarks [PDF]

, 2006
We discuss some aspects of cold atomic gases in the unitarity limit that are of interest in connection with the physics of dense hadronic matter. We consider, in particular, the equation of state at zero temperature, the magnitude of the pairing gap, and
