Cyclic tetraaryl[5]cumulenes (1a–f) have been synthesized and studied as a function of increasing ring strain. The magnitude of ring strain is approximated by the extent of bending of the cumulenic core as assessed by a combination of X-ray crystallographic analysis and DFT calculations. Trends...

Szymor-Pietrzak, Damian, Khan, Muhammad N., Pagès, Anaïs, Kumar, Ajay, Depner, Noah, Clive, Derrick L. J.
meta-Aminophenols are formed by the action of DBU on 3-amino-2-chlorocyclohex-2-en-1-ones at room temperature in MeCN. The chloro compounds are generated by treating 3- aminocyclohex-2-en-1-ones with the easily prepared halogenating agent BnNMe3.ICl2 in MeOHCH2Cl2. The amino group must carry two...

Sorochan Armstrong, Michael D., de la Mata, A. Paulina, Harynuk, James J.
Cluster resolution (CR) is a useful metric for guiding automated feature selection of classification models. CR is a measure of class separation in a linear subspace for variable subsets via the determination of maximal, non‐intersecting confidence ellipses. Feature selection by cluster...

Lead‐207 NMR spectroscopy at 1.4 T: Application of benchtop instrumentation to a challenging I = ½ nucleus
Download2020-01-01
Bernard, G.M., Michaelis, V.K.
The practicality of obtaining liquid‐ and solid‐state 207Pb nuclear magnetic resonance (NMR) spectra with a low permanent‐field magnet is investigated. Obtaining 207Pb NMR spectra of salts in solution is shown to be viable for samples as dilute as 0.05 M. The concentration dependence of the 207Pb...

Annealing induced structural evolution in feldspar dental glass-ceramics investigated by solid-state NMR spectroscopy
Download2020-01-01
Bhattacharya, A., Qiu, Y., Bernard, G.M., Butler, S., Mar, A., Michaelis, V.K.
Glass-ceramics are an attractive oxide-based material routinely used for biomineral repair such as porcelain veneers in dental crown applications. The short- and long-range structure of a commercial glass-ceramic feldspar material, VITA VM9, has been investigated as a function of annealing...

Tailorable Indirect to Direct Band-Gap Double Perovskites with Bright White-Light Emission: Decoding Chemical Structure Using Solid-State NMR
Download2020-01-01
Karmakar, A., Bernard, G.M., Meldrum, A., Oliynyk, A.O., Michaelis, V.K.
Efficient white-light-emitting single-material sources are ideal for sustainable lighting applications. Though layered hybrid lead–halide perovskite materials have demonstrated attractive broad-band white-light emission properties, they pose a serious long-term environmental and health risk as...

Isoenzyme-Selective Inhibitors of Human Neuraminidases Reveal Distinct Effects on Cell Migration
Download2020-04-20
Howlader, Md. Amran, Guo, Tianlin, Chakraberty, Radhika, Cairo, Christopher W.
The human neuraminidase enzymes (NEU1, NEU2, NEU3, and NEU4) are a class of enzymes implicated in pathologies including cancer and diabetes. Several reports have linked neuraminidase activity to the regulation of cell migration in cancer cells. Using an in vitro cell migration assay on...

Chlorella viruses produce N-linked glycoproteins with carbohydrate moieties that differ in structure from all other N- linked glycans. In addition, unlike most viruses, these organisms do not hijack the biosynthetic machinery of the host to make glycocoproteins; instead, they produce their own...
