Airey MW, Harrison RG, Nicoll KA, Williams PD, Marlton GJ.
PMID: 28863650
Rev Sci Instrum. 2017 Aug;88(8):086108. doi: 10.1063/1.4998971.

A lightweight and low power oscillating microbalance for in situ sampling of atmospheric ice and volcanic ash is described for airborne platforms. Using a freely exposed collecting wire fixed at only one end to a piezo transducer, the instrument...

Determining the location and nearest neighbours of aluminium in zeolites with atom probe tomography.

Nature communications

Perea DE, Arslan I, Liu J, Ristanović Z, Kovarik L, Arey BW, Lercher JA, Bare SR, Weckhuysen BM.
PMID: 26133270
Nat Commun. 2015 Jul 02;6:7589. doi: 10.1038/ncomms8589.

Zeolite catalysis is determined by a combination of pore architecture and Brønsted acidity. As Brønsted acid sites are formed by the substitution of AlO4 for SiO4 tetrahedra, it is of utmost importance to have information on the number as...

Direct observation of ice nucleation events on individual atmospheric particles.

Physical chemistry chemical physics : PCCP

Wang B, Knopf DA, China S, Arey BW, Harder TH, Gilles MK, Laskin A.
PMID: 27722496
Phys Chem Chem Phys. 2016 Nov 02;18(43):29721-29731. doi: 10.1039/c6cp05253c.

Heterogeneous ice nucleation is a physical chemistry process of critical relevance to a range of topics in the fundamental and applied sciences and technologies. Heterogeneous ice nucleation remains insufficiently understood, partially due to the lack of experimental methods capable...

N-Heterocyclic carbene-induced transmethylation in tungsten imido alkylidene bistriflates: unexpected formation of an N-heterocyclic olefin complex.

PMID: 26075999
Gynecol Oncol Rep. 2014 Oct 27;10:30-1. doi: 10.1016/j.gore.2014.10.002. eCollection 2014 Dec.

•Progesterone therapy is a commonly used alternative to surgical management for women with endometrial cancer who desire fertility preservation.•Prior research suggests that progestins may contribute to breast tumorigenesis.•We report a patient diagnosed with progesterone receptor positive breast cancer during...

Time-dependent density functional methods for Raman spectra in open-shell systems.

The journal of physical chemistry. A

Aquino FW, Schatz GC.
PMID: 24380604
J Phys Chem A. 2014 Jan 16;118(2):517-25. doi: 10.1021/jp411039m. Epub 2014 Jan 07.

We present an implementation of a time-dependent density functional theory (TD-DFT) linear response module in NWChem for unrestricted DFT calculations and apply it to the calculation of resonant Raman spectra in open-shell molecular systems using the short-time approximation. The...

Tip-enhanced Raman nanographs: mapping topography and local electric fields.

Nano letters

El-Khoury PZ, Gong Y, Abellan P, Arey BW, Joly AG, Hu D, Evans JE, Browning ND, Hess WP.

We report tip-enhanced Raman imaging experiments in which information on sample topography and local electric fields is simultaneously obtained using an all-optical detection scheme. We demonstrate how a Raman-active 4,4'-dimercaptostilbene (DMS)-coated gold tip of an atomic force microscope can...
