A Chemical Approach to the Modelling of Band Gap of Passive Films for Corrosion Studies

2015

Photocurrent Spectroscopy (PCS) has gained a large consideration in the last decades as in situ technique for the characterization of semiconductors and photoconducting passive film/electrolyte junctions being able to provide information on the location of characteristic energy levels like: flat band potential (Ufb), internal photoemission threshold (Eth) and band gap value (Eg)

Valoración de los cambios de los aniones orgánicos que participan en el equilibrio ácido-base al introducir un regimen de biofiltración sin acetato

2011

VALORACIÓN DE LOS CAMBIOS DE LOS ANIONES ORGÁNICOS QUE PARTICIPAN EN EL EQUILIBRIO ÁCIDO-BASE AL INTRODUCIR UN REGIMEN DE BIOFILTRACIÓN SIN ACETATO. La corrección de la situación de acidosis metabólica común a la insuficiencia renal crónica es uno de los objetivos prioritarios del tratamiento de sustitución dialítico. La diálisis es capaz de producir cambios en el perfil metabólico dependientes de la modalidad y del líquido empleados. Realizamos un estudio con 22 pacientes estables en programa de hemodiálisis que se sometieron de forma cruzada a dos modalidades de hemodiafiltracion una con 34 mmol/l de bicarbonato y 3 mmol/l de acetato (HDF) y la otra biofiltración sin acetato (AFB). Según …

Experimental and DFT studies on competitive heterocyclic rearrangements. part 2: A one-atom side-chain versus the classic three-atom side-chain (Boul…

2007

The experimental investigation of the base-catalyzed rearrangements of 3-acylamino-1,2,4-oxadiazoles evidenced a new reaction pathway which competes with the well-known ring-degenerate Boulton- Katritzky rearrangement (BKR). The new reaction consists of a one-atom side-chain rearrangement that is base-activated, occurs at a higher temperature than the BKR, and irreversibly leads to the corresponding 2-acylamino-1,3,4-oxadiazoles. An extensive DFT study is reported to elucidate the proposed reaction mechanism and to compare the three possible inherent routes: (i) the reversible three-atom side-chain ring-degenerate BKR, (ii) the ring contraction-ring expansion route (RCRE), and (iii) the one…
