Dental Pathology in ECT Patients Prior to Treatment.

Convulsive therapy

McCall WV, Minneman SA, Minneman SA, Weiner RD, Shelp FE, Austin S.
PMID: 11941145
Convuls Ther. 1992;8(1):19-24.

Dental complications during electroconvulsive therapy (ECT) are uncommon. Nevertheless, dental complications are often cited in ECT-related malpractice litigation. Choice of dental protection during ECT should be based on dental pathology prior to ECT. We describe the results of formal...

Adhesion force between cyclopentane hydrate and mineral surfaces.

Langmuir : the ACS journal of surfaces and colloids

Aman ZM, Leith WJ, Grasso GA, Sloan ED, Sum AK, Koh CA.
PMID: 24266729
Langmuir. 2013 Dec 17;29(50):15551-7. doi: 10.1021/la403489q. Epub 2013 Dec 05.

Clathrate hydrate adhesion forces play a critical role in describing aggregation and deposition behavior in conventional energy production and transportation. This manuscript uses a unique micromechanical force apparatus to measure the adhesion force between cyclopentane hydrate and heterogeneous quartz...

A molecular dynamics study of guest-host hydrogen bonding in alcohol clathrate hydrates.

Physical chemistry chemical physics : PCCP

Hiratsuka M, Ohmura R, Sum AK, Alavi S, Yasuoka K.
PMID: 25905113
Phys Chem Chem Phys. 2015 May 21;17(19):12639-47. doi: 10.1039/c4cp05732e.

Clathrate hydrates are typically stabilized by suitably sized hydrophobic guest molecules. However, it has been experimentally reported that isomers of amyl-alcohol C5H11OH can be enclosed into the 5(12)6(4) cages in structure II (sII) clathrate hydrates, even though the effective...

Quantitative measurement and mechanisms for CH4 production from hydrates with the injection of liquid CO2.

Physical chemistry chemical physics : PCCP

Lee BR, Koh CA, Sum AK.
PMID: 24931508
Phys Chem Chem Phys. 2014 Jul 28;16(28):14922-7. doi: 10.1039/c4cp01780c.

The recovery of gas from natural gas hydrates under the permafrost and in oceanic sediments is of particular interest in energy and environmental fields because of the attractive process to release methane gas through the injection of CO2. The...

Monte Carlo molecular simulation of the hydration of Na-montmorillonite at reservoir conditions.

The Journal of chemical physics

de Pablo L, Chávez ML, Sum AK, de Pablo JJ.
PMID: 15267930
J Chem Phys. 2004 Jan 08;120(2):939-46. doi: 10.1063/1.1631440.

The hydration of Na-saturated Wyoming-type montmorillonite is investigated by Monte Carlo simulations at constant stress in the NP(zz)T ensemble and at constant chemical potential in the microVT ensemble, at the sedimentary basin temperature of 353 K and pressure of...

Tetra-n-butylammonium borohydride semiclathrate: a hybrid material for hydrogen storage.

The journal of physical chemistry. A

Shin K, Kim Y, Strobel TA, Prasad PS, Sugahara T, Lee H, Sloan ED, Sum AK, Koh CA.
PMID: 19445522
J Phys Chem A. 2009 Jun 11;113(23):6415-8. doi: 10.1021/jp902547d.

In this study, we demonstrate that tetra-n-butylammonium borohydride [(n-C(4)H(9))(4)NBH(4)] can be used to form a hybrid hydrogen storage material. Powder X-ray diffraction measurements verify the formation of tetra-n-butylammonium borohydride semiclathrate, while Raman spectroscopic and direct gas release measurements confirm...

Jamming of particles in a two-dimensional fluid-driven flow.

Physical review. E, Statistical, nonlinear, and soft matter physics

Guariguata A, Pascall MA, Gilmer MW, Sum AK, Sloan ED, Koh CA, Wu DT.
PMID: 23367936
Phys Rev E Stat Nonlin Soft Matter Phys. 2012 Dec;86(6):061311. doi: 10.1103/PhysRevE.86.061311. Epub 2012 Dec 17.

The jamming of particles under flow is of critical importance in a broad range of natural and industrial settings, such as the jamming of ice in rivers, or the plugging of suspended solids in pipeline transport. Relatively few studies...

Observation of interstitial molecular hydrogen in clathrate hydrates.

Angewandte Chemie (International ed. in English)

Grim RG, Barnes BC, Lafond PG, Kockelmann WA, Keen DA, Soper AK, Hiratsuka M, Yasuoka K, Koh CA, Sum AK.
PMID: 25139731
Angew Chem Int Ed Engl. 2014 Sep 26;53(40):10710-3. doi: 10.1002/anie.201406546. Epub 2014 Aug 19.

The current knowledge and description of guest molecules within clathrate hydrates only accounts for occupancy within regular polyhedral water cages. Experimental measurements and simulations, examining the tert-butylamine + H2 + H2O hydrate system, now suggest that H2 can also...

Vibrational modes of methane in the structure H clathrate hydrate from ab initio molecular dynamics simulation.

The Journal of chemical physics

Hiratsuka M, Ohmura R, Sum AK, Yasuoka K.
PMID: 23061847
J Chem Phys. 2012 Oct 14;137(14):144306. doi: 10.1063/1.4757914.

Vibrational spectra of guest molecules in clathrate hydrates are frequently measured to determine the characteristic signatures of the molecular environment and dynamical properties of guest-host interactions. Here, we present results of our study on the vibrational frequencies of methane...

Phys Rev Lett. 2018 Aug 31;121(9):098003. doi: 10.1103/PhysRevLett.121.098003.

We establish the complete phase diagram of self-propelled hard disks in two spatial dimensions from the analysis of the equation of state and the statistics of local order parameters. The equilibrium melting scenario is maintained at small activities, with...
