Diazotizable supports of potential interest as affinity chromatography matrices
Journal of Molecular Recognition, 1996Immobilization of affinity ligands, proteins, enzymes and other functional groups by azo coupling is based on the high reactivity of the support-carrying diazonium groups towards both low- and high-molecular weight compounds containing certain groupings such as phenols, imidazole and some other heterocycles, thiols and amines.

Transfer matrices for one-dimensional potentials
Journal of Mathematical Physics, 1983The one-dimensional Schrödinger equation can be written as a first-order multicomponent equation by considering ψ and dψ/dx, or combinations thereof, as independent variables. A potential barrier is then represented by a matrix belonging to one of the homomorphic groups SU(1,1), SO(2,1), Sp(2,R), or SL(2,R).

Potential application of SERS for arsenic speciation in biological matrices
Analytical and Bioanalytical Chemistry, 2017Speciation of arsenic is usually carried out using chromatography-based methods coupled with spectroscopic determination; however, the inevitable procedures involving sample preparation and separation could potentially alter the integrity of the arsenic metabolites present in biological samples.

Exact exchange-correlation potential and approximate exchange potential in terms of density matrices
Physical Review A, 1995An exact expression in terms of density matrices (DM) is derived for \ensuremath{\delta}F[n]/\ensuremath{\delta}n(r), the functional derivative of the Hohenberg-Kohn functional. The derivation starts from the differential form of the virial theorem, obtained here for an electron system with arbitrary interactions, and leads to an expression taking the ...

Titanate matrices as potential corrosion inhibitor nanocontainers
Corrosion Science, 2014Layered titanates as inhibitor nanocontainers were studied in this paper. Pyridine as a typical inhibitor was introduced into the titanate matrices and its extraction from the matrices was studied. The results show that the increase of pH of media favors the extraction of pyridine from the matrices.
