Antimony film screen-printed carbon electrode for stripping analysis of Cd(II), Pb(II), and Cu(II) in natural samples.

Analytica chimica acta

Sosa V, Barceló C, Serrano N, Ariño C, Díaz-Cruz JM, Esteban M.
PMID: 25542087
Anal Chim Acta. 2015 Jan 15;855:34-40. doi: 10.1016/j.aca.2014.12.011. Epub 2014 Dec 10.

An in-situ antimony film screen-printed carbon electrode (in-situ SbSPCE) was successfully used for the determination of Cu(II) simultaneously with Cd(II) and Pb(II) ions, by means of differential pulse anodic stripping voltammetry (DPASV), in a certified reference groundwater sample with...

Desiccation tolerance in resurrection plants: new insights from transcriptome, proteome and metabolome analysis.

Frontiers in plant science

Dinakar C, Bartels D.
PMID: 24348488
Front Plant Sci. 2013 Nov 28;4:482. doi: 10.3389/fpls.2013.00482. eCollection 2013.

Most higher plants are unable to survive desiccation to an air-dried state. An exception is a small group of vascular angiosperm plants, termed resurrection plants. They have evolved unique mechanisms of desiccation tolerance and thus can tolerate severe water...

The main aim of this study is to describe the relationship between serum levels of atazanavir, renal toxicity, and lithiasis. This is a prospective observational study of patients being treated with atazanavir (ATV) at Son Espases Teaching Hospital, Palma...

[28]Hexaphyrin derivatives for anion recognition in organic and aqueous media.

Chemical communications (Cambridge, England)

Figueira F, Farinha AS, Muteto PV, Polêto MD, Verli H, Gomes MT, Tomé AC, Cavaleiro JA, Tomé JP.
PMID: 26725320
Chem Commun (Camb). 2016 Feb 04;52(10):2181-4. doi: 10.1039/c5cc08128a.

Hexaphyrin-based anion chemosensors are reported for the first time. The meso-hexakis(ethylenediamine)-substituted [28]hexaphyrins 2 and 3 revealed strong affinity for F(-), AcO(-) and H2PO4(-). Adsorption constants in aqueous media were determined on a gold piezoelectric crystal coated with 2 and...

On a boundary-localized Higgs boson in 5D theories.

The European physical journal. C, Particles and fields

Barceló R, Mitra S, Moreau G.
PMID: 26566383
Eur Phys J C Part Fields. 2015;75(11):527. doi: 10.1140/epjc/s10052-015-3756-3. Epub 2015 Nov 05.

In the context of a simple five-dimensional (5D) model with bulk matter coupled to a brane-localized Higgs boson, we point out a non-commutativity in the 4D calculation of the mass spectrum for excited fermion towers: the obtained expression depends...

Selective trace enrichment of chlorotriazine pesticides from natural waters and sediment samples using terbuthylazine molecularly imprinted polymers.

Analytical chemistry

Anal Chem. 2000 Aug 15;72(16):3934-41. doi: 10.1021/ac000015f.

Two molecularly imprinted polymers were synthesized using either dichloromethane or toluene as the porogen and terbuthylazine as the template and were used as solid-phase extraction cartridges for the enrichment of six chlorotriazines (deisopropylatrazine, deethylatrazine, simazine, atrazine, propazine, and terbuthylazine)...

Evaluation of a multidimensional solid-phase extraction platform for highly selective on-line cleanup and high-throughput LC-MS analysis of triazines in river water samples using molecularly imprinted polymers.
