Molecular orbital diagrams are commonly taught and used for describing chemical bonding chemistry courses including courses at the college level. Misconceptions that occur when students construct and/or use these diagrams are difficult to anticipate,

Interest in student-centered active learning pedagogies is widespread, but discipline-specific examples of implemented instructional approaches are needed to bridge the gap between pedagogical ideas and their enactment. One of these approaches, Model

Poly(3-methylthiophene) (P3MT) was synthesized directly from indium tin oxide (ITO) electrodes modified with a phosphonic acid initiator, using Kumada catalyst transfer polymerization (KCTP). This work represents the first time that polymer thickness

We present a comparison of the photovoltaic activity of organic solar cells (OPVs) based on vacuum-deposited and solvent-annealed titanyl phthalocyanine (TiOPc) donor layers with C60 as the electron acceptor, where the TiOPc donor layer exists in thr

Organic photovoltaic devices have been created on activated and modified ITO electrodes from electrodeposited poly(3-hexylthiophene) (e-P3HT) donor layers, using pulsed-potential-step (PPS) electrodeposition protocols. PPS electrodeposition uses a se

We use electroabsorption spectroscopy to measure the change in built-in potential (VBI) across the polymer photoactive layer in diodes where indium tin oxide electrodes are systematically modified using dipolar phosphonic acid self-assembled monolaye

By adding a large quantity of Cl− to an aqueous solution of CoCl2·6H2O, a mixture containing a red octahedral cobalt complex and a blue tetrahedral complex is produced. When the solution temperature is modified, the equilibrium constant, Keq, of t

Polythiophene films can be electrodeposited on modified ITO substrates, textured to increase their active surface area, doped to enhance charge transport, and then interfaced with C60 thin films to create “planar heterojunction” photovoltaic devi

An EDTA complex of terbium(III) was evaluated via phosphorescence spectroscopy in the presence of varying quantities of quencher TEMPOL. Both steady-state excitation via a xenon lamp and pulsed excitation via a nitrogen laser were used to allow the q
