Multinuclear Magnetic Resonance Tracking of Hydro, Thermal and Hydrothermal Decomposition of CH3NH3PbI3

Askar, A.,, Bernard, G.M, Wiltshire,, B., Shankar, K., Michaelis, V.K.
An NMR investigation of methylammonium lead iodide, the leading member of the hybrid organic-inorganic perovskite class of materials, and of its putative decomposition products as a result of exposure to heat and humidity, has been undertaken. We show that the 207Pb NMR spectra of the compound of...

Nair, Sindhu G., Loppnow, Glen R.
The exposure of DNA to ultraviolet (UV) radiation causes sequence‐dependent damage. Thus, there is a need for an analytical technique that can detect damage in large numbers of DNA sequences simultaneously. In this study, we have designed an assay for UVC‐induced DNA damage in multiple...

Janus poly (N-isopropylacrylamide)-co-acrylic acid/Au microgels that resemble a “snowman”, “dumbbell”, and an “abalone” were prepared by thermally evaporating a layer of Au on half of the microgel surface, followed by exposure to thiolated single-stranded DNA with complementary sequences. We...

Nonspecific interactions between proteins and charged biomolecules in electrospray ionization mass spectrometry
Download2010
Soya, Naoto, Klassen, John S., Kitova, Elena N., Sun, Nian
An investigation of the nonspecific association of small charged biomolecules and proteins in electrospray ionization mass spectrometry (ES-MS) is described. Aqueous solutions containing pairs of proteins and a small acidic or basic biomolecule that does not interact specifically with either of...

O-GlcNAcase uses substrate-assisted catalysis Kinetic analysis and development of highly selective mechanism-inspired inhibitors

Vocadlo, David J., Whitworth, Garrett E., Macauley, Matthew S., Debowski, Aleksandra W., Chin, Danielle
The post-translational modification of serine and threonine residues of nucleocytoplasmic proteins with 2-acetamido-2-deoxy-d-glucopyranose (GlcNAc) is a reversible process implicated in multiple cellular processes. The enzyme O-GlcNAcase catalyzes the cleavage of β-O-linked GlcNAc (O-GlcNAc)...

Zhang, Qiang, Berg, Darren, Duan, Jiaqi, Mugo, Samuel M., Serpe, Michael J.
Ferrocene-modified poly(N-isopropylacrylamide)-based microgels were synthesized, characterized, and used to construct optical devices (etalons). The response of the microgels and etalons to H2O2 was investigated, and we show that both the microgel diameter and the optical properties of the...

P. aeruginosa SGNH hydrolase-like proteins AlgJ and AlgX have similar topology but separate and distinct roles in alginate acetylation

Howell, P. Lynne, Klassen, John S., Robinson, Howard, Kitova, Elena N., Dawson, Karen, Clarke, Anthony J., Little, Dustin J., Walvoort, Marthe T., Weadge, Joel T., Codee, Jeroen D. C., Baker, Perrin, Whitney, John C., Ohman, Dennis E., Ricer, Tyler, Moynihan, Patrick J.
The O-acetylation of polysaccharides is a common modification used by pathogenic organisms to protect against external forces. Pseudomonas aeruginosa secretes the anionic, O-acetylated exopolysaccharide alginate during chronic infection in the lungs of cystic fibrosis patients to form the major...

Penetration of polyelectrolytes into charged poly (N-isopropylacrylamide) microgel layers confined between two surfaces

Islam, Molla R., Serpe, Michael J.
pH and temperature sensitive poly(N-isopropylacrylamide) (pNIPAm) microgel-based etalons were fabricated by sandwiching a “monolithic” microgel layer between two semitransparent, 15 nm Au layers. The devices exhibit visual color and multipeak reflectance spectra, both of which primarily depend on...

Ha, M., Karmakar, A., Bernard, G.M., Basilio, E., Krishnamurthy, A., Askar, A.M., Shankar, K., Kroeker, S., Michaelis, V.K.
Hybrid organic–inorganic metal-halide perovskite materials are an emerging class of materials that could profoundly change the optoelectronic and solar absorber research fields and have far-reaching applications. Unfortunately, the leading solar-absorbing candidates are lead-containing materials...
