Fragile‐to‐Strong Crossover in Supercooled Liquid Ag‐In‐Sb‐Te Studied by Ultrafast Calorimetry

02-Jul-2015 | Jiri Orava, Daniel W. Hewak, A. Lindsay Greer, Advanced Functional Materials, 2015

Phase‐change random‐access memory relies on the reversible crystalline‐glassy phase change in chalcogenide thin films. In this application, the speed of crystallization is critical for device performance: there is a need to combine ultrafast crystallization for switching at high temperature with ...

Mechanism of Photochemical O-Atom Exchange in Nitrosamines with Molecular Oxygen

05-Jun-2015 | Marilene Silva Oliveira; Ashwini A. Ghogare; Inna Abramova; Edyta M. Greer; Fernanda Manso Prado; Paolo Di Mascio; A ..., The Journal of Organic Chemistry, 2015

The detection of an oxygen-atom photoexchange process of N-nitrosamines is reported. The photolysis of four nitrosamines (N-nitrosodiphenylamine 1, N-nitroso-N-methylaniline 2, N-butyl-N-(4-hydroxybutyl)nitrosamine 3, and N-nitrosodiethylamine 4) with ultraviolet light was examined in an ...

New horizons for glass formation and stability

01-Jun-2015 | A. Lindsay Greer, Nature Materials, 2015

Nature Materials 14, 542 (2015). doi:10.1038/nmat4292 Author: A. Lindsay Greer It has long been thought impossible for pure metals to form stable glasses. Recent work supports...

Development and characterization of novel 8‐plex DiLeu isobaric labels for quantitative proteomics and peptidomics

12-May-2015 | Dustin C. Frost, Tyler Greer, Feng Xiang, Zhidan Liang, Lingjun Li, Rapid Communications in Mass Spectrometry, 2015

Rationale Relative quantification of proteins via their enzymatically digested peptide products determines disease biomarker candidate lists in discovery studies. Isobaric label‐based strategies using TMT and iTRAQ allow for up to 10 samples to be multiplexed in one experiment, but their ...

Three-Dimensional Au Microlattices as Positive Electrodes for Li–O2 Batteries

12-May-2015 | Chen Xu; Betar M. Gallant; Phillip U. Wunderlich; Timm Lohmann; Julia R. Greer, ACS Nano, 2015

We demonstrate the feasibility of using a 3-dimensional gold microlattice with a periodic porous structure and independently tunable surface composition as a Li–O2 battery cathode. The structure provides a platform for studying electrochemical reactions in architected Li–O2 electrodes with large ...

Odorant receptors regulate the final glomerular coalescence of olfactory sensory neuron axons [Neuroscience]

05-May-2015 | Diego J. Rodriguez-Gil; Dianna L. Bartel; Austin W. Jaspers; Arie S. Mobley; Fumiaki Imamura; Charles A. Greer, Proceedings of the National Academy of Sciences current issue, 2015

Odorant receptors (OR) are strongly implicated in coalescence of olfactory sensory neuron (OSN) axons and the formation of olfactory bulb (OB) glomeruli. However, when ORs are first expressed relative to basal cell division and OSN axon extension is unknown. We developed an in vivo fate-mapping ...

Tailoring of Interfacial Mechanical Shear Strength by Surface Chemical Modification of Silicon Microwires Embedded in Nafion Membranes

27-Apr-2015 | Betar M. Gallant; X. Wendy Gu; David Z. Chen; Julia R. Greer; Nathan S. Lewis, ACS Nano, 2015

The interfacial shear strength between Si microwires and a Nafion membrane has been tailored through surface functionalization of the Si. Acidic (−COOH-terminated) or basic (−NH2-terminated) surface-bound functionality was introduced by hydrosilylation reactions to probe the interactions between ...

Butylated hydroxytoluene enediyne: access to diradical and electrophilic quinone methide intermediates

02-Mar-2015 | Edyta M. Greer, Cesar S. Quezada, Christopher V. Cosgriff, Journal of Physical Organic Chemistry, 2015

A theoretical study was carried out on the unimolecular reaction of an enediyne with a fused butylated hydroxytoluene to internally scavenge the p‐benzyne diradical sites formed after the Bergman cyclization. The calculations revealed that the conversion of the p‐benzyne diradical ...

Photoactive Fluoropolymer Surfaces That Release Sensitizer Drug Molecules

26-Feb-2015 | Goutam Ghosh; Mihaela Minnis; Ashwini A. Ghogare; Inna Abramova; Keith A. Cengel; Theresa M. Busch; Alexander Greer, Journal of Physical Chemistry B, 2015

We describe a physical–organic study of two fluoropolymers bearing a photoreleasable PEGylated photosensitizer that generates 1O2(1Δg) [chlorin e6 methoxy tri(ethylene glycol) triester]. The surfaces are Teflon/poly(vinyl alcohol) (PVA) nanocomposite and fluorinated silica. The relative ...
