Addressing Racial/Ethnic Equity in Access to COVID-19 Testing Through Drive-Thru And Walk-In Testing Sites in Chicago.

Mile Square Health Center (MSHC), a network of Federally Qualified Health Centers (FQHCs) run by the University of Illinois Hospital (UIH) in Chicago, established Drive-Thru and Walk-Up COVID-19 testing sites. The primary aim of the UIH/MSHC testing project was to increase testing capacity in the most affected, racial/ethnic minority communities. More than 7,500 tests were performed over a six-month period.

Efficient graphene-coated iron oxide (GCIO) nanoadsorbent for removal of lead and arsenic ions.

The graphene-coated iron oxide (GCIO) was used for the removal of Pb and As ions from aqueous solution. For the characterization of GCIO, several techniques (FTIR, XRD, EDX, SEM, TEM, TGA, DSC and vibrating sample magnetometry) were used which indicated the interaction of Pb and As with adsorbent. In addition, the effects of adsorbate concentration, different composition of adsorbent, temperature, pH of the solution and contact time of adsorbate-adsorbent were studied.

Structural and redox properties of mitochondrial cytochrome c co-sorbed with phosphate on hematite (alpha-Fe2O3) surfaces.

The interaction of metalloproteins with oxides has implications not only for bioanalytical systems and biosensors but also in the areas of biomimetic photovoltaic devices, bioremediation, and bacterial metal reduction. Here, we investigate mitochondrial ferricytochrome c (Cyt c) co-sorption with 0.01 and 0.

XANES investigation of phosphate sorption in single and binary systems of iron and aluminum oxide minerals.

Phosphate sorption on Fe- and Al-oxide minerals helps regulate the solubility and mobility of P in the environment. The objective of this study was to characterize phosphate adsorption and precipitation in single and binary systems of Fe- and Al-oxide minerals. Varying concentrations of phosphate were reacted for 42 h in aqueous suspensions containing goethite, ferrihydrite, boehmite, or noncrystalline (non-xl) Al-hydroxide, and in 1:1 (by mass) mixed-mineral suspensions of goethite/boehmite and ferrihydrite/ non-xl Al-hydroxide at pH 6 and 22 degrees C.
