Photocatalytic oxidation of pharmaceutical micropollutants in a flow-through reactor
… on glass slides was used to develop a model flow-through reactor to study dynamic photocatalytic treatment processes. Light is supplied by black light bulbs, which emit light in the ultraviolet-A range. Experiments have shown this to be an effective method for degradation of these four drug …

Manganese dioxide reduction kinetics by Geobacter sulfurreducens and associated biofilm morphology in a flow-through reactor
… that convert metals to lower redox states through oxidation and reduction reactions. They utilize more metal than is needed for biosynthesis because they can conserve energy through the reduction of metals. This ability of DMRBs permits them to influence nutrient cycling in marine and …

Nanomaterials and photonic solutions. Novel ‘at source’ approaches to stop hospital-derived priority substances reaching the sewer network.
… properties to ensure efficient diffusion through cell membranes. As a result, many excreted drugs enter wastewater largely unmetabolized as active ingredients and can cause potentially toxic effects in non-target organisms and accumulate in food chains. As many drugs are present in …

Lead Sorption Efficiencies of Natural and Sunthetic Mn and Fe-oxides
… natural and synthetic Mn and Fe-oxides using a flow through reactor. The Mn-oxide phases examined included synthetic birnessite, natural and synthetic cryptomelane, and natural and synthetic pyrolusite; the Fe-oxides studied were synthetic akaganeite, synthetic ferrihydrite, natural and …

Shewanella oneidensis MR-1 cell-to-cell signaling and its influences on biogeochemical processes
… Within 16 hours of growth in a biofilm flow-through reactor, the luxS mutant had an inhibited ability to initiate biofilm formation. After 48 hours of growth, the mutant's biofilm had developed similarly to wild-type. The addition of synthetic AI-2 did not restore the mutant's ability to …

Catalytic Upgrading of Lignin From Biomass
… as a solid residue. Using a custom-built flow-through reactor, we determined the mechanisms under which the catalyst was rapidly deactivating, we learned what factors limit rates of lignin extraction from biomass, and we began to understand how the biosynthetic production of lignin in the …

Geochemical Conditions Affecting Uranium(VI) Fate And Transport In Soil And Groundwater In The Presence Of Phosphate
… mechanisms and rate was examined. Continuous-flow stirred tank reactor: CFSTR) experiments at pH 4 were conducted under conditions supersaturated and undersaturated with respect to chernikovite and analyzed using a combination of measured dissolved concentrations, microscopy, and XAFS …

Elucidation of the Catalytic Partial Oxidation of Methane Utilizing the One-of-a-Kind Catalytic Shock Tube Technique
… CO<sub>2</sub>, H<sub>2</sub> and H<sub>2</sub>O through either partial oxidation followed by complete oxidation or complete oxidation followed by reforming steps. What is happening when the reaction is allowed to occur in an environment absent of transport limitations, absent of temperature …

Enhanced Microbial Sulfate Removal Through a Novel Electrode-Integrated Bioreactor
… developed a sediment bioelectrochemical batch reactor that used a low electrical potential to enhance and sustain biological sulfate reduction by continuously supplying electron donor substrates (electrolytic hydrogen) to sulfate reducing bacteria. The project aims to understand the effect of a …
