Heat and mass transfer across interfaces in complex nanogeometries.

Physical review letters

Wilhelmsen Ø, Trinh TT, Kjelstrup S, van Erp TS, Bedeaux D.
PMID: 25723229
Phys Rev Lett. 2015 Feb 13;114(6):065901. doi: 10.1103/PhysRevLett.114.065901. Epub 2015 Feb 12.

Heat and mass transfer in nanodevices depends much on the geometry due to the strong influence of curvature on interfacial properties, such as the Kapitza resistance. We present a method which combines nonequilibrium square gradient theory and nonequilibrium molecular...

Rare event simulations reveal subtle key steps in aqueous silicate condensation.

Physical chemistry chemical physics : PCCP

Moqadam M, Riccardi E, Trinh TT, Lervik A, van Erp TS.
PMID: 28492680
Phys Chem Chem Phys. 2017 May 24;19(20):13361-13371. doi: 10.1039/c7cp01268c.

A replica exchange transition interface sampling (RETIS) study combined with Born-Oppenheimer molecular dynamics (BOMD) is used to investigate the dynamics, thermodynamics and the mechanism of the early stages of the silicate condensation process. In this process, two silicate monomers,...

Investigation of intrathecal transport of NPT002, a prospective therapeutic based on phage M13, in nonhuman primates.

Drug delivery and translational research

Papisov MI, Belov V, Belova E, Fischman AJ, Fisher R, Wright JL, Gannon KS, Titus J, Gagne M, Gillooly CA.

Drug Deliv Transl Res. 2012 Jun;2(3):210-21. doi: 10.1007/s13346-012-0074-2.

Presently, there are no effective treatments for conditions characterized by protein misfolding, such as Alzheimer's, Parkinson's, and other diseases involving CNS. Since misfolding occurs at the earliest stage of the disease, it is likely to be involved in subsequent...

Design considerations for a new, high resolution Micro-Angiographic Fluoroscope based on a CMOS sensor (MAF-CMOS).

Proceedings of SPIE--the International Society for Optical Engineering

Loughran B, Swetadri Vasan SN, Singh V, Ionita CN, Jain A, Bednarek DR, Titus A, Rudin S.
PMID: 24353389
Proc SPIE Int Soc Opt Eng. 2013 Mar 06;8668. doi: 10.1117/12.2006430.

The detectors that are used for endovascular image-guided interventions (EIGI), particularly for neurovascular interventions, do not provide clinicians with adequate visualization to ensure the best possible treatment outcomes. Developing an improved x-ray imaging detector requires the determination of estimated...

Carbon tunneling from a single quantum state.

Science (New York, N.Y.)

Zuev PS, Sheridan RS, Albu TV, Truhlar DG, Hrovat DA, Borden WT.
PMID: 12574623
Science. 2003 Feb 07;299(5608):867-70. doi: 10.1126/science.1079294.

We observed ring expansion of 1-methylcyclobutylfluorocarbene at 8 kelvin, a reaction that involves carbon tunneling. The measured rate constants were 4.0 x 10(-6) per second in nitrogen and 4 x 10(-5) per second in argon. Calculations indicated that at...

Circular dichroism of 1,3-dioxane-type (2'-naphthyl)methylene acetals of glycosides.

Chirality

Kurtán T, Borbás A, Szabó ZB, Lipták A, Bényei A, Antus S.
PMID: 15034907
Chirality. 2004 May 05;16(4):244-50. doi: 10.1002/chir.20019.

The CD spectra are reported for a series of 1,3-dioxane-type 4,6-O-(2'-naphthyl)methylene acetals of carbohydrates with and without interacting aromatic protective groups on the C-1, C-2, and C-3 hydroxy groups. In the absence of interacting chromophores, the signs of the...

Isolation and partial characterization of an Acid endoprotease present in dormant apple shoot bark.

Plant physiology

Kang SM, Titus JS.
PMID: 16661565
Plant Physiol. 1980 Nov;66(5):984-9. doi: 10.1104/pp.66.5.984.

A major protease present in dormant bark tissues of the apple (Malus domestica Borkh. cv. "Golden Delicious") was partially purified by hemoglobin-coupled Sepharose column chromatography. The protease active at pH 4.6 and at temperatures of 30 to 50 C...

Environmental applications of gas chromatography/atomic emission detection.

Analytical chemistry

Gurka DF, Pyle S, Titus R.
PMID: 21639376
Anal Chem. 1997 Jul 01;69(13):2411-7. doi: 10.1021/ac9612739.

A gas chromatograph/atomic emission detector (GC/AED) system has been evaluated for its applicability to environmental analysis. Detection limits, elemental response factors, and regression analysis data were determined for 58 semivolatile environmental contaminants. Detection limits for injected analytes ranged from...

Hydrogen in chemical vapour deposited carbon nanotubes: an active site for functionalization.

Journal of nanoscience and nanotechnology

Titus E, Cabral G, Madaleno JC, Coelho MC, Babu PR, Blau WJ, Misra DS, Gracio J.
PMID: 19049170
J Nanosci Nanotechnol. 2008 Aug;8(8):4017-22. doi: 10.1166/jnn.2008.an34.

The presence of hydrogen in as-grown carbon nanotubes (CNTs) synthesized by microwave plasma (MP) chemical vapour deposition (CVD) technique is demonstrated. Our results showed that the MPCVD, as-grown CNTs were hydrogenated consisting of C-H bonds; whereas, the tubes synthesized...

Prediction of the mechanical properties of hydroxyapatite/polymethyl methacrylate/carbon nanotubes nanocomposite.

Journal of nanoscience and nanotechnology

Shokuhfar T, Makradi A, Titus E, Cabral G, Ahzi S, Sousa AC, Belouettar S, Gracio J.

J Nanosci Nanotechnol. 2008 Aug;8(8):4279-84. doi: 10.1166/jnn.2008.an26.

In this work carbon nanotubes (CNTs) were used to increase the strength and toughness of the hydroxyapatite (HA) and consequently to reduce its brittleness. The combination of CNT, HA and polymethyl methacrylate (PMMA) has led to a new composite...
