Nondiffracting Bessel beams with polarization state that varies with propagation distance.

Optics letters

Moreno I, Davis JA, Sánchez-López MM, Badham K, Cottrell DM.
PMID: 26625023
Opt Lett. 2015 Dec 01;40(23):5451-4. doi: 10.1364/OL.40.005451.

We generate nondiffracting Bessel beams whose polarization state varies with propagation distance. We use a reflective geometry where a single parallel-aligned spatial light modulator device is used to spatially modulate two orthogonal linear polarizations with two axicon phase profiles....

Vector Beam Polarization State Spectrum Analyzer.

Scientific reports

Moreno I, Davis JA, Badham K, Sánchez-López MM, Holland JE, Cottrell DM.
PMID: 28533509
Sci Rep. 2017 May 22;7(1):2216. doi: 10.1038/s41598-017-02328-5.

We present a proof of concept for a vector beam polarization state spectrum analyzer based on the combination of a polarization diffraction grating (PDG) and an encoded harmonic q-plate grating (QPG). As a result, a two-dimensional polarization diffraction grating...

Dual polarization split lenses.

Cofré A, Vargas A, Torres-Ruiz FA, Campos J, Lizana A, Sánchez-López MM, Moreno I.
PMID: 29041328
Opt Express. 2017 Oct 02;25(20):23773-23783. doi: 10.1364/OE.25.023773.

We report the realization of polarization sensitive split lens configurations. While split lenses can be used to easily generate different types of controlled structured light patterns, their realization has been limited so far to scalar beams. Here we propose...

Diffraction gratings generating orders with selective states of polarization.

Optics express

Davis JA, Moreno I, Sánchez-López MM, Badham K, Albero J, Cottrell DM.
PMID: 26832474
Opt Express. 2016 Jan 25;24(2):907-17. doi: 10.1364/OE.24.000907.

We propose specially designed double anisotropic polarization diffraction gratings capable of producing a selective number of diffraction orders and with selective different states of polarization. Different polarization diffraction gratings are demonstrated, including linear polarization with horizontal, vertical and ±...

Fractional Fourier transforms, symmetrical lens systems, and their cardinal planes.

Journal of the Optical Society of America. A, Optics, image science, and vision

Moreno I, Sánchez-López MM, Ferreira C, Mateos F.
PMID: 17728815
J Opt Soc Am A Opt Image Sci Vis. 2007 Jul;24(7):1930-6. doi: 10.1364/josaa.24.001930.

We study the relation between optical lens systems that perform a fractional Fourier transform (FRFT) with the geometrical cardinal planes. We demonstrate that lens systems symmetrical with respect to the central plane provide an exact FRFT link between the...

Effect of crude plant extracts from some Oaxacan flora on two deleterious fungal phytopathogens and extract compatibility with a biofertilizer strain.

Frontiers in microbiology

Lira-De León KI, Ramírez-Mares MV, Sánchez-López V, Ramírez-Lepe M, Salas-Coronado R, Santos-Sánchez NF, Valadez-Blanco R, Hernández-Carlos B.
PMID: 25147544
Front Microbiol. 2014 Aug 05;5:383. doi: 10.3389/fmicb.2014.00383. eCollection 2014.

The antimicrobial activity of 12 plant extracts was tested against the phytopathogens Alternaria alternata and Fusarium solani. In addition, the compatibility of the extracts toward Bacillus liqueniformis, a biofertilizer and a non-target microorganism, was assessed. Plants tested belong to...

Neuroprotective alpha-cleavage of the human prion protein significantly impacts Cu(ii) coordination at its His111 site.

Dalton transactions (Cambridge, England : 2003)

Sánchez-López C, Fernández CO, Quintanar L.
PMID: 29417110
Dalton Trans. 2018 Jul 17;47(28):9274-9282. doi: 10.1039/c7dt03400h.

The cellular prion protein (PrPC) is a copper binding protein that undergoes post-translational modifications, such as endoproteolytic alpha cleavage, which occurs in the vicinity of the His111 Cu binding site. Alpha cleavage processing of PrPC is considered to be...

Q-plates with a nonlinear azimuthal distribution of the principal axis: application to encoding binary data.

Applied optics

Holland JE, Moreno I, Davis JA, Sánchez-López MM, Cottrell DM.
PMID: 29469877
Appl Opt. 2018 Feb 10;57(5):1005-1010. doi: 10.1364/AO.57.001005.

We encode q-plates where the angular orientation of the principal axis is varied spatially with a nonstandard distribution. In the usual q-plate design, the orientation of the optical axis depends linearly on the azimuthal angle. In this work, we...

Pharmaceutics. 2019 Sep 06;11(9). doi: 10.3390/pharmaceutics11090460.

The eye presents extensive perspectives and challenges for drug delivery, mainly because of the extraordinary capacity, intrinsic to this path, for drugs to permeate into the main circulatory system and also for the restrictions of the ocular barriers. Depending...
