A comparative study of surface energies and water adsorption on Ce-bastnäsite, La-bastnäsite, and calcite via density functional theory and water adsorption calorimetry.

Physical chemistry chemical physics : PCCP

Goverapet Srinivasan S, Shivaramaiah R, Kent PR, Stack AG, Riman R, Anderko A, Navrotsky A, Bryantsev VS.
PMID: 28262886
Phys Chem Chem Phys. 2017 Mar 15;19(11):7820-7832. doi: 10.1039/c7cp00811b.

Bastnäsite, a fluoro-carbonate mineral, is the single largest mineral source of light rare earth elements (REE), La, Ce and Nd. Enhancing the efficiency of separation of the mineral from gangue through froth flotation is the first step towards meeting...

Heterogeneous Nucleation and Growth of Barium Sulfate at Organic-Water Interfaces: Interplay between Surface Hydrophobicity and Ba(2+) Adsorption.

Langmuir : the ACS journal of surfaces and colloids

Dai C, Stack AG, Koishi A, Fernandez-Martinez A, Lee SS, Hu Y.

Langmuir. 2016 May 31;32(21):5277-84. doi: 10.1021/acs.langmuir.6b01036. Epub 2016 May 18.

Barium sulfate (BaSO4) is a common scale-forming mineral in natural and engineered systems, yet the rates and mechanisms of heterogeneous BaSO4 nucleation are not understood. To address these, we created idealized interfaces on which to study heterogeneous nucleation rates...

Toward optimized potential functions for protein-protein interactions in aqueous solutions: osmotic second virial coefficient calculations using the MARTINI coarse-grained force field.

Journal of chemical theory and computation

Stark AC, Andrews CT, Elcock AH.
PMID: 24223529
J Chem Theory Comput. 2013 Sep 10;9(9). doi: 10.1021/ct400008p.

Coarse-grained (CG) simulation methods are now widely used to model the structure and dynamics of large biomolecular systems. One important issue for using such methods - especially with regard to using them to model, for example, intracellular environments -...

Determining the incidence of the hereditary form of retinoblastoma.

PMID: 27275484
Ann Transl Med. 2016 May;4(9):171. doi: 10.21037/atm.2016.05.05.

Retinoblastoma (Rb) is used here as the prototype of a condition which has a dominant mode of inheritance. Under the two-hit model of carcinogenesis, a germinal mutation may be followed by somatic mutation producing a tumour or tumours, in...

A Search for pi/sigma Equilibria in Chiral Rhenium Imine Complexes of the Formula [(eta(5)-C(5)H(5))Re(NO)(PPh(3))(N(H)=C(CF(3))X)](+)TfO(-): Investigation of Electronic Effects upon the Binding Mode.

Reaction of the amido complex (eta(5)-C(5)H(5))Re(NO)(PPh(3))(&Numl;H(2)) (2) and hexafluoroacetone gives the methyleneamido complex (eta(5)-C(5)H(5))Re(NO)(PPh(3))(&Numl;=C(CF(3))(2)) (3, 58%). Addition of TfOH to 3 yields the sigma-imine complex [(eta(5)-C(5)H(5))Re(NO)(PPh(3))(eta(1)-N(H)=C(CF(3))(2))](+)TfO(-) (4, 96%). Similar reactions of 2 with trifluoroacetaldehyde and then TfOH give the...

Educating back-injured workers: What should we be teaching?.

Work (Reading, Mass.)

Hazard RG, Reid S, Clark AA.
PMID: 12441485
Work. 2000;15(3):159-166.

OBJECTIVE: The purpose of this study was to identify what information people with acute and chronic back pain, health care practitioners, employers and case managers felt should be included in an educational brochure for recently back-injured workers. STUDY DESIGN:...

Exploring Women's Preferences for Labor Epidural Analgesia.

The Journal of perinatal education

Stark MA.
PMID: 17273336
J Perinat Educ. 2003;12(2):16-21. doi: 10.1624/105812403X106793.

The purpose of this study was to explore demographic factors related to women's prenatal preferences for using an epidural during labor. Women recruited from prenatal classes provided data for this descriptive correlational study. Women with the most education, income,...

Astigmatic coherence sensor for digital imaging.

Optics letters

PMID: 18066327
Opt Lett. 2000 Dec 01;25(23):1726-8. doi: 10.1364/ol.25.001726.

We present a novel sensor that measures the entire spatial coherence function within an aperture by use of a variable astigmatic lens. This sensor permits digital capture and processing of partially coherent fields. We demonstrate the sensor by sampling...

Watching the assembly of an organ a single cell at a time using confocal multi-position photoactivation and multi-time acquisition.

Organogenesis

PMID: 20539744
Organogenesis. 2009 Oct;5(4):238-47. doi: 10.4161/org.5.4.10482.

Tracing cell movements in vivo yields important clues to organogenesis, yet it has been challenging to accurately and reproducibly fluorescently mark single and small groups of cells to build a picture of tissue assembly. In the early embryo, the...

Three-dimensional tomography using a cubic-phase plate extended depth-of-field system.

Optics letters

Marks DL, Stack RA, Brady DJ, van der Gracht J.
PMID: 18071471
Opt Lett. 1999 Feb 15;24(4):253-5. doi: 10.1364/ol.24.000253.

We use cubic-phase plate imaging to demonstrate an order-of-magnitude improvement in the transverse resolution of three-dimensional objects reconstructed by extended depth-of-field tomography. Our algorithm compensates for the range shear of the cubic-phase approach and uses camera rotation to center...
