Free-standing nanocomposite multilayers with various length scales, adjustable internal structures, and functionalities.

Journal of the American Chemical Society

Lee S, Lee B, Kim BJ, Park J, Yoo M, Bae WK, Char K, Hawker CJ, Bang J, Cho J.
PMID: 19183049
J Am Chem Soc. 2009 Feb 25;131(7):2579-87. doi: 10.1021/ja8064478.

We introduce an innovative and robust method for the preparation of nanocomposite multilayers, which allows accurate control over the placement of functional groups as well as the composition and dimensions of individual layers/internal structure. By employing the photocross-linkable polystyrene...

Structure of rutile TiO2 (110)-(1 x 2): formation of Ti2O3 quasi-1D metallic chains.

Physical review letters

Blanco-Rey M, Abad J, Rogero C, Mendez J, Lopez MF, Martin-Gago JA, de Andres PL.
PMID: 16486946
Phys Rev Lett. 2006 Feb 10;96(5):055502. doi: 10.1103/PhysRevLett.96.055502. Epub 2006 Feb 06.

Combining STM, LEED, and density functional theory, we determine the atomic surface structure of rutile TiO2 (110)-(1 x 2): nonstoichiometric Ti2O3 stripes along the [001] direction. LEED patterns are sharp and free of streaks, while STM images show monatomic...

Quantum tunneling of a vortex between two pinning potentials.

Physical review letters

Fialko O, Bradley AS, Brand J.
PMID: 22304264
Phys Rev Lett. 2012 Jan 06;108(1):015301. doi: 10.1103/PhysRevLett.108.015301. Epub 2012 Jan 03.

A vortex can tunnel between two pinning potentials in an atomic Bose-Einstein condensate on a time scale of the order of 1s under typical experimental conditions. This makes it possible to detect the tunneling experimentally. We calculate the tunneling...

A Lipid Requirement for Photosystem I Activity in Heptane-extracted Spinach Chloroplasts.

Plant physiology

Brand J, Krogmann DW, Crane FL.
PMID: 16657568
Plant Physiol. 1971 Jan;47(1):135-8. doi: 10.1104/pp.47.1.135.

A lipid requirement for photosystem I activity in Spinacia oleracea chloroplasts has been characterized. The transfer of electrons from tetramethyl-p-phenylenediamine through the chloroplast photosystem to viologen dye was used as an assay of photosystem I activity. Activity is diminished...

Prevalence and Factors Associated with Renal Dysfunction in HIV Positive and Negative Adults at the University Teaching Hospital, in Lusaka.

Medical journal of Zambia

Banda J, Mweemba A, Siziya S, Mweene M, Andrews B, Lakhi S.
PMID: 24363467
Med J Zambia. 2010 Jul;37(3):136-142.

BACKGROUND: Despite having the highest disease burden of HIV, Sub-Saharan Africa has limited data on HIV related kidney disease with most available data coming from the developed countries. Kidney disease is a recognised complication in HIV infected patients presenting...

Patient feedback via a national registry could improve physicians' CME.

B═B and B≡E (E = N and o) multiple bonds in the coordination sphere of late transition metals.

Accounts of chemical research

Brand J, Braunschweig H, Sen SS.
PMID: 23952302
Acc Chem Res. 2014 Jan 21;47(1):180-91. doi: 10.1021/ar400106u. Epub 2013 Aug 16.

Because of their unusual structural and bonding motifs, multiply bonded boron compounds are fundamentally important to chemists, leading to enormous research interest. To access these compounds, researchers have introduced sterically demanding ligands that provide kinetic as well as electronic...

Difference in Early Activation of NF-κB and MCP-1 in Acinar-Cell-Rich versus Fibrotic Human Pancreas Exposed to Surgical Trauma and Hypoxia.

Gastroenterology research and practice

Laaninen M, Bläuer M, Sand J, Nordback I, Laukkarinen J.
PMID: 25147563
Gastroenterol Res Pract. 2014;2014:460363. doi: 10.1155/2014/460363. Epub 2014 Jul 24.

Objectives. Previously we have shown that a pancreas with over 40% acinar cells is exposed to postoperative pancreatitis and other complications after pancreaticoduodenectomy (PD). Our aim was to analyze the expression of NF-κB and MCP-1 in the cut edge...

Confirmatory Factor Analysis and Test-Retest Reliability of the Alcohol and Drug Confrontation Scale (ADCS).

Journal of drug issues

Polcin DL, Galloway GP, Bond J, Korcha R, Greenfield TK.
PMID: 20686635
J Drug Issues. 2009 Sep;39(4):931-948. doi: 10.1177/002204260903900408.

The addiction field lacks an accepted definition and reliable measure of confrontation. The Alcohol and Drug Confrontation Scale (ADCS) defines confrontation as warnings about the potential consequences of substance use. To assess psychometric properties, 323 individual entering recovery houses...

Nucleation in finite topological systems during continuous metastable quantum phase transitions.

Physical review letters

Fialko O, Delattre MC, Brand J, Kolovsky AR.
PMID: 23004576
Phys Rev Lett. 2012 Jun 22;108(25):250402. doi: 10.1103/PhysRevLett.108.250402. Epub 2012 Jun 20.

Finite topological quantum systems can undergo continuous metastable quantum phase transitions to change their topological nature. Here we show how to nucleate the transition between ring currents and dark soliton states in a toroidally trapped Bose-Einstein condensate. An adiabatic...
