Kinetic Modeling of Series Reaction CH4-CH3OH-DME with CuO-ZnO/-Al2O3 Catalyst

open access: yesJurnal Bahan Alam Terbarukan, 2018
A kinetic model was proposed for the synthesis of methane to be dimethyl ether (DME) in one reaction step from (CH4 + O2) and (CH3OH) to dimethyl ether using kinetic CuO-ZnO /Al2O3 catalyst parameters.

HCCI Combustion Engine Fueled with DME and DME-Reformed Gas

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 2004
Dimethyl ether has been studied as a fuel for homogeneous-charge compression-ignition combustion (HCCI) engine by many researchers. However, there is a difficulty to control the ignition timing in accordance with the engine load. This research newly proposes a DME fueled HCCI combustion engine system with an ignition control by DME-reformed gas (DRG ...

Spatially Selective Solvation Chemistry by Local Charge Enrichment for Stable Potassium‐Metal Anodes

open access: yesAdvanced Science, EarlyView.
A MoC/NC functional intermediate medium preferentially interacts with KFSI to reconstruct the interfacial solvation structure and form a KF‐rich inorganic SEI. The synergistic integration of the electronically insulating SEI and MoC/NC suppresses electron tunneling, enables fast and balanced K+/electron transport, and promotes uniform K deposition for ...

An X-ray polarimeter for hard X-ray optics [PDF]

open access: yes, 2006
Development of multi-layer optics makes feasible the use of X-ray telescope at energy up to 60-80 keV: in this paper we discuss the extension of photoelectric polarimeter based on Micro Pattern Gas Chamber to high energy X-rays.

Interfacial Polysulfide Confinement via Spatially Controlled Sulfonated Metal–Organic Polyhedra Coatings in Lithium–Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
Spatially controlled sulfonated metal–organic polyhedra (SMOP) coating on sulfur‐loaded hollow carbon spheres form ultrathin, conformal interfacial barriers that selectively confine soluble polysulfides, stabilize sulfur redox, and suppress shuttle reactions.

An improved density matrix expansion for spin-unsaturated nuclei

open access: yes, 2010
A current objective of low-energy nuclear theory is to build non-empirical nuclear energy density functionals (EDFs) from underlying inter-nucleon interactions and many-body perturbation theory (MBPT).
