Dynamic Triple-Mode Sorption and Outgassing in Materials.

Scientific reports

Sharma HN, Harley SJ, Sun Y, Glascoe EA.
PMID: 28592891
Sci Rep. 2017 Jun 07;7(1):2942. doi: 10.1038/s41598-017-03091-3.

Moisture uptake and outgassing can be detrimental to a system by altering the chemical and mechanical properties of materials within the system over time. In this work, we conducted isotherm experiments to investigate dynamic moisture sorption and desorption in...

Ligand rearrangement reactions of Cr(CO)6 in alcohol solutions: experiment and theory.

The journal of physical chemistry. B

Shanoski JE, Glascoe EA, Harris CB.
PMID: 16471634
J Phys Chem B. 2006 Jan 19;110(2):996-1005. doi: 10.1021/jp055636x.

The ligand rearrangement reaction of Cr(CO)6 is studied in a series of alcohol solutions using ultrafast infrared spectroscopy and Brownian dynamics simulations. Excitation with 266 nm light gives Cr(CO)5 which is quickly solvated by a ligand from the bath....

Modeling and Uncertainty Quantification of Vapor Sorption and Diffusion in Heterogeneous Polymers.

Chemphyschem : a European journal of chemical physics and physical chemistry

Sun Y, Harley SJ, Glascoe EA.
PMID: 26274619
Chemphyschem. 2015 Oct 05;16(14):3072-83. doi: 10.1002/cphc.201500372. Epub 2015 Aug 13.

A high-fidelity model of kinetic and equilibrium sorption and diffusion is developed and exercised. The gas-diffusion model is coupled with a triple-sorption mechanism: Henry's law absorption, Langmuir adsorption, and pooling or clustering of molecules at higher partial pressures. Sorption...

Time-resolved IR studies on the mechanism for the functionalization of primary C-H bonds by photoactivated Cp*W(CO)3(Bpin).

Journal of the American Chemical Society

Sawyer KR, Cahoon JF, Shanoski JE, Glascoe EA, Kling MF, Schlegel JP, Zoerb MC, Hapke M, Hartwig JF, Webster CE, Harris CB.
PMID: 20099849
J Am Chem Soc. 2010 Feb 17;132(6):1848-59. doi: 10.1021/ja906438a.

Recently, transition-metal-boryl compounds have been reported that selectively functionalize primary C-H bonds in alkanes in high yield. We have investigated this process with one of the well-defined systems that reacts under photochemical conditions using both density functional theory calculations...

Should PGY-1 Be Mandatory in Dental Education? Two Viewpoints: Viewpoint 1: PGY-1 Provides Benefits That Support Making It Mandatory and Viewpoint 2: PGY-1 Should Be Available for Dental Graduates But Not Mandatory.

Journal of dental education

Dhar V, Glascoe A, Esfandiari S, Williams KB, McQuistan MR, Stevens MR.
PMID: 27803199
J Dent Educ. 2016 Nov;80(11):1273-1281.

This Point/Counterpoint considers whether a general dentistry postgraduate year one (PGY-1) residency should be required for all new graduates who do not pursue specialty training. Currently, New York and Delaware require PGY-1 for dental licensure, while other states offer...

Advances in modeling sorption and diffusion of moisture in porous reactive materials.

Chemphyschem : a European journal of chemical physics and physical chemistry

Harley SJ, Glascoe EA, Lewicki JP, Maxwell RS.
PMID: 24819028
Chemphyschem. 2014 Jun 23;15(9):1809-20. doi: 10.1002/cphc.201301097. Epub 2014 May 12.

Water-vapor-uptake experiments were performed on a silica-filled poly(dimethylsiloxane) (PDMS) network and modeled by using two different approaches. The data was modeled by using established methods and the model parameters were used to predict moisture uptake in a sample. The...

Pressure-dependent decomposition kinetics of the energetic material HMX up to 3.6 GPa.

The journal of physical chemistry. A

Glascoe EA, Zaug JM, Burnham AK.
PMID: 19827806
J Phys Chem A. 2009 Dec 03;113(48):13548-55. doi: 10.1021/jp905276k.

The effect of pressure on the global thermal decomposition rate of the energetic material HMX was studied. HMX was precompressed in a diamond anvil cell (DAC) and heated at various rates. The parent species population was monitored as a...

Direct observation of photoinduced bent nitrosyl excited-state complexes.

The journal of physical chemistry. A

Sawyer KR, Steele RP, Glascoe EA, Cahoon JF, Schlegel JP, Head-Gordon M, Harris CB.
PMID: 18729431
J Phys Chem A. 2008 Sep 18;112(37):8505-14. doi: 10.1021/jp802705w. Epub 2008 Aug 27.

Ground-state structures with side-on nitrosyl (eta (2)-NO) and isonitrosyl (ON) ligands have been observed in a variety of transition-metal complexes. In contrast, excited-state structures with bent-NO ligands have been proposed for years but never directly observed. Here, we use...

Predicting 3D moisture sorption behavior of materials from 1D investigations.

Scientific reports

Sharma HN, Sun Y, Glascoe EA.
PMID: 33082520
Sci Rep. 2020 Oct 20;10(1):17852. doi: 10.1038/s41598-020-74898-w.

Moisture in materials can be a source of future outgassing and exacerbate unwanted changes in physical and chemical properties. Here, we investigate the effect of sample size and shape on the moisture transport phenomena through a combined experimental and...

Acrylamide Production in Autoclaved Rodent Feed.

Journal of the American Association for Laboratory Animal Science : JAALAS

Kurtz DM, Glascoe R, Caviness G, Locklear J, Whiteside T, Ward T, Adsit F, Lih F, Deterding LJ, Churchwell MI, Doerge DR, Kissling GE.
PMID: 30360773
J Am Assoc Lab Anim Sci. 2018 Oct 25; doi: 10.30802/AALAS-JAALAS-18-000011. Epub 2018 Oct 25.

Sterilization of rodent feed by steam autoclaving is a common practice in many research institutions. Often we only considerthe beneficial effects of this process-the reduction of microbial contamination-and forget that the high temperatures andpressures can have negative effects on...
