The effect of inorganic semivolatile aerosol compounds on the cloud condensation nucleus (CCN) activity of aerosol particles was studied by using a computational model for a DMT-CCN counter, a cloud parcel model for condensation kinetics and experiments to ...
This work demonstrates the rational design of a dedicated hydrolysis catalyst for application in the selective catalytic reduction (SCR) of NOx. Modification of titania by lanthanum prior to gold deposition entailed highly improved catalytic activities for ...
The effect of surface functionalities, specific surface area and pore size of activated carbon fibers (ACFs) on the adsorption of toluene and acetaldehyde, two volatile organic compounds (VOC), at low concentrations (similar to 80 ppmv) and short contact t ...
Ammonium formate (AmFo) and formic acid decomposition were carried out in the presence of excess O-2 and H2O over 0.5 wt%Au/TiO2 anatase monolithic catalysts using various contact times and temperatures between 160 degrees C and 300 degrees C, under spray ...
The first near-IR fluorescent turn-on sensor for the detection of nitroxyl (HNO), the one-electron reduced form of nitric oxide (NO), is reported. The new copper-based probe, CuDHX1, contains a dihydroxanthene (DHX) fluorophore and a cyclam deriv. as a Cu( ...
The interactions of trivalent lanthanides and actinides with secondary mineral phases such as calcite is of high importance for the safety assessment of deep geological repositories for high level nuclear waste (HLW). Due to similar ionic radii, calcium-be ...
In the present work, two pretreatment techniques using either dilute acid (H2SO4) or dilute alkali (NaOH) have been compared for producing bioethanol from Empty Fruit Bunches (EFBs) from oil palm tree, a relevant feedstock for tropical countries. Treatment ...
Widespread production of biomass-derived fuels and chemicals will require cost-effective processes for breaking down cellulose and hemicellulose into their constituent sugars. Here, we report laboratory-scale production of soluble carbohydrates from corn s ...
A carbon support was treated with HNO3 to create surface functional groups (e.g. -COOH, -OH), which were then characterized by TGA, TPD, CNS elemental analysis, and Boehm titration. HNO3 modified the carbon surface properties by adding a high amount of car ...
We demonstrate an experimental approach for upgrading lignin that has been isolated from corn stover via biomass fractionation using c-valerolactone (GVL) as a solvent. This GVL-based approach can be used in parallel with lignin upgrading to produce solubl ...
