PMID: 26452868
Talanta. 2015 Nov 01;144:612-8. doi: 10.1016/j.talanta.2015.06.072. Epub 2015 Jul 02.

In this work, the use of a portable Raman spectrometer is evaluated for the non-invasive analysis of two types of pre-ignited improvised incendiary devices (IIDs), the classic Molotov cocktails and the chemical ignition Molotov cocktails (CIMCs). The most common...

Stereospecific Allylic Functionalization: The Reactions of Allylboronate Complexes with Electrophiles.

Journal of the American Chemical Society

García-Ruiz C, Chen JL, Sandford C, Feeney K, Lorenzo P, Berionni G, Mayr H, Aggarwal VK.
PMID: 29028321
J Am Chem Soc. 2017 Nov 01;139(43):15324-15327. doi: 10.1021/jacs.7b10240. Epub 2017 Oct 20.

Allylboronic esters react readily with carbonyls and imines (π-electrophiles), but are unreactive toward a range of other electrophiles. By addition of an aryllithium, the corresponding allylboronate complexes display enhanced nucleophilicity, enabling addition to a range of electrophiles (tropylium, benzodithiolylium,...

A study to visualize and determine the sequencing of intersecting ink lines.

Forensic science international

Ozbek N, Braz A, López-López M, García-Ruiz C.
PMID: 24378300
Forensic Sci Int. 2014 Jan;234:39-44. doi: 10.1016/j.forsciint.2013.10.026. Epub 2013 Oct 31.

Determining the sequencing of intersecting ink lines is one of the current problems for forensic document examiners. The way two inks will distribute and interact with each other and the paper at the crossing is a dynamic process that...

Single-shot distributed temperature and strain tracking using direct detection phase-sensitive OTDR with chirped pulses.

Optics express

Pastor-Graells J, Martins HF, Garcia-Ruiz A, Martin-Lopez S, Gonzalez-Herraez M.
PMID: 27410330
Opt Express. 2016 Jun 13;24(12):13121-33. doi: 10.1364/OE.24.013121.

So far, the optical pulses used in phase-sensitive OTDR (ΦOTDR) were typically engineered so as to have a constant phase along the pulse. In this work, it is demonstrated that by acting on the phase profile of the optical...

Nucleation and growth of the Naica giant gypsum crystals.

Chemical Society reviews

Otálora F, García-Ruiz J.
PMID: 24264125
Chem Soc Rev. 2014 Apr 07;43(7):2013-26. doi: 10.1039/c3cs60320b. Epub 2013 Nov 21.

The Cave of Giant Crystals in the Naica mine (Mexico) is one of the most amazing displays of mineral beauty ever created in nature. In addition to the colossal crystals of gypsum, which in some cases exceed eleven meters...

Parametric characterization of surface plasmon polaritons at a lossy interface.

Optics express

Martinez-Herrero R, Garcia-Ruiz A, Manjavacas A.
PMID: 26561127
Opt Express. 2015 Nov 02;23(22):28574-83. doi: 10.1364/OE.23.028574.

Using exact solutions of Maxwell's equations, we investigate the evolution of the transversal profile of a surface plasmon polariton (SPP) packet propagating along a planar interface between a dielectric and a lossy metal. We introduce a parameter to measure...

Glutathione and mitochondria.

Frontiers in pharmacology

Ribas V, García-Ruiz C, Fernández-Checa JC.
PMID: 25024695
Front Pharmacol. 2014 Jul 01;5:151. doi: 10.3389/fphar.2014.00151. eCollection 2014.

Glutathione (GSH) is the main non-protein thiol in cells whose functions are dependent on the redox-active thiol of its cysteine moiety that serves as a cofactor for a number of antioxidant and detoxifying enzymes. While synthesized exclusively in the...

Study of consumer fireworks post-blast residues by ATR-FTIR.

Talanta

Martín-Alberca C, Zapata F, Carrascosa H, Ortega-Ojeda FE, García-Ruiz C.
