Removing Oxide Layers and Retaining Oxide‐Free Steel Surfaces by Polishing in Oxygen‐Free Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
In this study, the efficacy of wet mechanical polishing under an oxygen‐free atmosphere for deoxidation and the retention of an oxide‐free steel surface are elucidated using X‐ray photoelectron spectroscopy. The methodology proved successful; however, the results were highly dependent on the preparation of the solvents used to clean the samples after ...

Metal-promoted mesoporous ZSM5 for CO methanation to produce synthetic natural gas (SNG) [PDF]

open access: yes, 2014
In recent years, enormous emissions of carbon oxide (CO and CO2) by combustion of fossil and fuel have contributed to the increase in global temperatures and climate changes due to the ‘greenhouse effect’ [1].

Evolution of water diffusion in a sorption-enhanced methanation catalyst [PDF]

open access: yes, 2018
Sorption-enhanced methanation has consequent advantages compared to conventional methanation approaches; namely, the production of pure methane and enhanced kinetics thanks to the application of Le Châtelier’s principle.

Continuous flow photoassisted CO2 methanation [PDF]

open access: yesSustainable Energy & Fuels, 2017
Photoassisted CO2 methanation using Ni–Al2O3/SiO2 as a photoresponsive catalyst has been carried out at 225 °C under continuous flow conditions achieving up to 3.5% conversion of CO2 with complete selectivity to CH4 under 2327 W m−2 irradiation for a contact time of 1.3 s.

Impact of Sustainable Binders Based on Lignin and Collagen on the Volume Stability and Mechanical Properties of MgO‐C Refractories with MgO‐C Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

Experimental investigation on CO2methanation process for solar energy storage compared to CO2-based methanol synthesis [PDF]

open access: yes, 2017
The utilization of the captured CO2 as a carbon source for the production of energy storage media offers a technological solution for overcoming crucial issues in current energy systems. Solar energy production generally does not match with energy demand

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

open access: yesAdvanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.
