Interest in using various nanoparticle catalysts to activate H2O2 with light for organic contaminant and wastewater treatment is steadily increasing. We successfully synthesized magnetically recoverable Cu0.5Mn0.5Fe2O4 nanoparticles using a simple co-precipitation method followed by melamine-assisted calcination. Material characterization revealed that melamine acted as a coordinating agent during the calcination process that promoted a ferrite structure. Copper (Cu)-substitution effectively decreased material aggregation and promoted catalytic activities. Cu0.5Mn0.5Fe2O4 nanoparticles showed outstanding catalytic performance on several organic contaminants (87.6–100.0% removal within 2 h). Using oxytetracycline (OTC) …

Feasibility Discussion Of Potential Carbon Offsetting Options For Nebraska, Andrew Mwape
Feasibility Discussion Of Potential Carbon Offsetting Options For Nebraska, Andrew Mwape
School of Natural Resources: Faculty Publications
Conclusion
Highlighting the advantages and disadvantages of carbon offsetting options in the context of the state of Nebraska, this discussion shows that the choice and decisions about which option is better than the other depends on the interests at play and expected outcomes of the participation in carbon markets. However, irrespective of the motive to engage in emission reduction projects for carbon marketing, factors such as cost, and project efficiency can never be overlooked. Given the options discussed in this report, Nebraska has a lot of potential for carbon offsetting or emission reduction projects that would not only reduce and …

Carbamazepine (CBZ) is the most frequently detected pharmaceutical residues in aquatic environments effluent by wastewater treatment plants. Batch and column experiments were con-ducted to evaluate the removal of CBZ from ultra-pure water and wastewater treatment plant (WWTP) effluent using raw zeolitic tuff (RZT) and surfactant modified zeolite (SMZ). Point zero net charge (pHpzc), X-ray diffraction (XRD), X-ray fluorescence (XRF), and Fourier Transform Infrared (FTIR) were investigated for adsorbents to evaluate the physiochemical changes resulted from the modification process using Hexadecyltrimethylammonium bromide (HDTMA-Br). XRD and FTIR showed that the surfactant modification of RZT has created an amorphous surface with new alkyl …

Corn Belt Soil Carbon And Macronutrient Budgets With Projected Sustainable Stover Harvest, Zhengxi Tan, Shuguang Liu
Corn Belt Soil Carbon And Macronutrient Budgets With Projected Sustainable Stover Harvest, Zhengxi Tan, Shuguang Liu
United States Geological Survey: Staff Publications
Corn (Zea mays L.) stover has been identified as a prime feedstock for biofuel production in the U.S. Corn Belt because of its perceived abundance and availability, but long-term stover harvest effects on regional nutrient budgets have not been evaluated. We defined the minimum stover requirement (MSR) to maintain current soil organic carbon levels and then estimated current and future soil carbon (C), nitrogen (N), phosphorus (P), and potassium (K) budgets for various stover harvest scenarios. Analyses for 2006 through 2010 across the entire Corn Belt indicated that currently, 28 Tg or 1.6 Mgha-1 of stover could be sustainably …
