Anthropogenic pollutants have the potential to disrupt reproductive strategies. Little is known about how lead (Pb2+) exposure disrupts individual-level responses in reproductive behaviors, which are important for fitness. Drosophila melanogaster was

Understanding speciation requires the identification of traits that cause reproductive isolation. This remains a major challenge since it is difficult to determine which of the many divergent traits actually caused speciation. To overcome this diffic

We report on atomic force microscopy (AFM) studies of polyaniline (PANI) nanostructures formed during different stages of in situ film growth. Surface topography and single molecule force spectroscopy results indicate that early stage and late stage

Nuclear magnetic resonance spectroscopy (NMR) is a viable alternative to current methods to introduce enzymatic reactions and monitor kinetics in the undergraduate curriculum. Using NMR to observe the invertase-catalyzed conversion of sucrose to fruc

Laponite films provide versatile inorganic scaffolds with materials architectures that direct the self-assembly of CdSe quantum dots (QDs or EviTags) and catalytic surfaces that promote the in situ polymerization of polyaniline (PANI) to yield novel

A novel low-temperature intramolecular exchange was detected by (13)C NMR spectrometry in the Na(+) and K(+) salts of the title compound. The process causes the pairwise exchange in the dianion ring of C(2"), C(3"), and C(4") with C(8"), C(7"), and C

The rate constants for bond shift (k(BS)) in phenylcyclooctatetraene (1b) and its p-nitro and p-methoxy analogues (1a and 1c, respectively) in THF-d(8) were determined by dynamic NMR spectrometry to be identical, but k(BS) is eight times greater at 2
