A tribal‐scale phylogenomic perspective on ancestry and major lineages of the allotetraploid Hawaiian silversword alliance (Madieae, Compositae)

American Journal of Botany, EarlyView.
Abstract Premise Disentangling the ancestry of insular plant lineages is important for resolving their evolutionary histories but often complicated by polyploidy, an overrepresented condition in remote island floras. We used a phylogenomic approach to study the origin of subgenomes of the tetraploid Hawaiian silversword alliance and advance ...

Methane-rich syngas production in an integrated fluidized bed by coupling pyrolysis and gasification of low-rank coal

, 2015
An integrated fluidized bed which combines a fluidized bed gasifier and a transport bed pyrolyzer was proposed to produce CH4-rich syngas from coupling pyrolysis and gasification of low-rank powder coal below 10 mm. This study investigated the effects of

Research on the Interaction Mechanisms between ScCO₂ and Low-Rank/High-Rank Coal with the ReaxFF-MD Force Field

Molecules
CO2 geological sequestration in coal seams can be carried out to achieve the dual objectives of CO2 emission reduction and enhanced coalbed methane production, making it a highly promising carbon capture and storage technology.

Methane adsorption characteristics and adsorbed gas content of low-rank coal in China

, 2016
Coalbed methane (CBM) reserve of low-rank coal (R < 0.65), occupying a proportion of more than 40% of the total CBM reserve of China, is 14.7 × 10 m. The exploration degree, particularly in situ gas content estimation of low-rank CBM reservoirs in China,

CO‐Adsorption on MgO Revisited: Polarization‐Resolved Identification of Step Edges as the Dominant Defects on MgO(100) and MgO(110)

Angewandte Chemie International Edition, EarlyView.
By combining polarization‐resolved IRRAS with hybrid HSE06 DFT calculations, we establish site‐specific vibrational fingerprints, adsorption geometries, and binding energies for CO on wide‐band‐gap MgO surfaces. Low‐coordinated Mg4c2+ step‐edge sites, rather than terrace Schottky defects, are identified as the dominant binding and reactive sites, with ...

Modeling and Simulation on NOx and N2O Formation in Co-combustion of Low-rank Coal and Palm Kernel Shell

Jurnal Rekayasa Kimia & Lingkungan, 2012
NOx and N2O emissions from coal combustion are claimed as the major contributors for the acid rain, photochemical smog, green house and ozone depletion problems.
