The Review of scientific instruments

Arutunian SG, Chung M, Harutyunyan GS, Margaryan AV, Lazareva EG, Lazarev LM, Shahinyan LA.
PMID: 26931835
Rev Sci Instrum. 2016 Feb;87(2):023108. doi: 10.1063/1.4941837.

We propose a new type of wire scanner for beam profile measurements, based on the use of a vibrating wire as a scattering target. Synchronous measurements with the wire oscillation allow to detect only the signal coming from the...

Climate Change and the Impact of Greenhouse Gasses: CO.

Frontiers in plant science

Cassia R, Nocioni M, Correa-Aragunde N, Lamattina L.
PMID: 29545820
Front Plant Sci. 2018 Mar 01;9:273. doi: 10.3389/fpls.2018.00273. eCollection 2018.

Here, we review information on how plants face redox imbalance caused by climate change, and focus on the role of nitric oxide (NO) in this response. Life on Earth is possible thanks to greenhouse effect. Without it, temperature on...

Rapid multiresidue determination of bisphenol analogues in soil with on-line derivatization.

Analytical and bioanalytical chemistry

Pérez RA, Albero B, Férriz M, Tadeo JL.
PMID: 28573319
Anal Bioanal Chem. 2017 Jul;409(19):4571-4580. doi: 10.1007/s00216-017-0399-2. Epub 2017 Jun 02.

Bisphenol analogues are compounds extensively used which have been potentially linked to adverse health effects. Nevertheless, few studies reported the analysis of compounds, other than bisphenol A, in environmental solid samples and none in soil samples. In this study,...

Histologic and molecular analysis of patient derived xenografts of high-grade serous ovarian carcinoma.

Journal of hematology & oncology

Dong R, Qiang W, Guo H, Xu X, Kim JJ, Mazar A, Kong B, Wei JJ.
PMID: 27655386
J Hematol Oncol. 2016 Sep 21;9(1):92. doi: 10.1186/s13045-016-0318-6.

BACKGROUND: Patient derived xenografts (PDX) are generated by transplanting the original patient's tumor tissue into immune-deficient mice. Unlike xenograft models derived from cell lines, PDX models can better preserve the histopathology from the original patient and molecular pathways. High-grade...

Measurements of double-polarized compton scattering asymmetries and extraction of the proton spin polarizabilities.

The spin polarizabilities of the nucleon describe how the spin of the nucleon responds to an incident polarized photon. The most model-independent way to extract the nucleon spin polarizabilities is through polarized Compton scattering. Double-polarized Compton scattering asymmetries on...

Photoelectrochemical Reduction of Carbon Dioxide on Quantum-Dot-Modified Electrodes by Electric Field Directed Layer-by-Layer Assembly Methodology.

ACS applied materials & interfaces

Guzmán D, Isaacs M, Osorio-Román I, García M, Astudillo J, Ohlbaum M.

Carbene complexes of rhodium and iridium from tripodal N-heterocyclic carbene ligands: synthesis and catalytic properties.

Inorganic chemistry

Mas-Marzá E, Poyatos M, Sanaú M, Peris E.
PMID: 15018547
Inorg Chem. 2004 Mar 22;43(6):2213-9. doi: 10.1021/ic035317p.

Two tripodal trisimidazolium ligand precursors have been tested in the synthesis of new N-heterocyclic carbene rhodium and iridium complexes. [Tris(3-methylbenzimidazolium-1-yl)]methane sulfate gave products with coordination of the decomposed precursor. [1,1,1-Tris(3-butylimidazolium-1-yl)methyl]ethane trichloride (TIMEH(3)(Bu)) coordinated to the metal in a chelate...

Opt Lett. 2008 Nov 15;33(22):2626-8. doi: 10.1364/ol.33.002626.

We calculate the spectrum of three-photon absorption (3PA) in zinc blende semiconductors using Kane's four-band model. We apply this to ZnSe and measure the 3PA spectrum using femtosecond pulses, obtaining excellent agreement. The spectrum shows the apparent onset of...
