Nanomaterials are quickly becoming highly useful for many applications. The public is concerned with the long-term effects of nanomaterials in the environment. Composite materials as substrates for nanoparticles can be tailored to maintain functionality as well as immobilize the nanoparticles to reduce health concerns. Our patent pending approach u...

Potassium iron hexacyanoferrate, or Prussian blue (PB), is investigated as a cathode material for nonaqueous divalent calcium ion batteries. PB is an attractive prospect due to its high specific capacity, nontoxicity, low cost, and simple synthesis. Charge/discharge performances are examined at current densities of 23 mA/g, 45 mA/g, 90 mA/g, and 12...

With the increasing prevalence of portable electronics, electric vehicles, and intermittent sources of renewable energy, comes greater demand for high energy density rechargeable batteries. At present, most commercial rechargeable batteries utilize the Li + ion as a charge carrier, with cathodes composed of lithium-doped metal oxides [1]. While lit...

This experiment compared the procedures, results, and yields of two \green" methods of synthesizing tetraphenylporphyrin (TPP) through an electrophilic aromatic substitution reaction between benzaldehyde and pyrrole. The two syntheses take advantage of high heat to mitigate the need for corrosive and toxic solvents. One procedure utilized a standar...
