Electrochemical oxidation of refractory compounds from hydrothermal carbonization process waters.

Hydrothermal carbonization (HTC) is an emerging technology for treating sewage sludge. However, the resulting HTC process water is heavily contaminated with various carbonaceous and nitrogenous components, some of them being non-biodegradable. To implement HTC as a full-scale treatment alternative for sewage sludge, effective concepts for treating process water are crucial.

Multiscale micro-architecture of pore space in rocks: size, shape, deformation and accessibility determined by small-angle neutron scattering (SANS).

A brief summary of the evolving applications of small-angle neutron scattering (SANS) to the microstructural research on geological materials in the last few decades is provided, including new developments and possible future directions. This is an account of authors' view of the interplay between the technical development of SANS instrumentation, methodology and sample environments and the progress of research on the evolution of organic matter, gas adsorption and desorption, fluid transport in the pore space and the microstructure of rocks, based mostly on their own research interests.

Discovering Inherent Characteristics of Polyethylenimine-Functionalized Porous Materials for CO Capture.

CO capture is vital for addressing greenhouse gas (GHG)-based environmental issues worldwide. Amine-polymer/silica sorbents have been extensively studied for CO capture, but the fundamental understandings of polyethylenimine (PEI) loading effect, thermal effect, and CO sorption behavior are still lacking. Small-angle neutron scattering (SANS) offers promising opportunities for characterizing CO sorption behavior of PEI-functionalized SBA-15.

Monitoring phase behavior of sub- and supercritical CO2 confined in porous fractal silica with 85% porosity.

Phase behavior of CO(2) confined in porous fractal silica with volume fraction of SiO(2) phi(s) = 0.15 was investigated using small-angle neutron scattering (SANS) and ultrasmall-angle neutron scattering (USANS) techniques. The range of fluid densities (0 < (rho(CO(2)))(bulk) < 0.
