The authors have studied the electrochem. oxidn. of H2SO4 on B-doped synthetic diamond electrodes (BDD) obtained by hot filament CVD on p-Si. High current efficiency for H2SO4 oxidn. to peroxodisulfuric acid can be achieved in concd. H2SO4 (>2M) at moderat ...
This paper characterizes the basic electrokinetic phenomena occurring within native poly(dimethylsiloxane) (PDMS) microchannels. Using simple buffers and current measurements, current density and electroosmosis data were determined in trapezoidal, reversib ...
A device, method and kit for the electrophoretic separation and purification of charged and neutral compounds in an analyte solution. The device comprises a chamber (1), at least one wall of which is composed of a chemical buffering system (4). A potential ...
This study has characterized the energetics of both the liquid state and the solid state of two commercially available epoxy resins: a DGEBA- and a TGMDA-based epoxy system. The surface properties of the liquid epoxies were evaluated by wetting measurement ...
Glutamate uptake into astrocytes and the resulting increase in intracellular Na+ (Na+(i)) have been identified as a key signal coupling excitatory neuronal activity to increased glucose utilization. Arguments based mostly on mathematical modeling led to th ...
The oxidation of organic and inorganic compounds during ozonation can occur via ozone or OH radicals or a combination thereof. The oxidation pathway is determined by the ratio of ozone and OH radical concentrations and the corresponding kinetics. A huge da ...
Hexyl aminolevulinate (HAL) fluorescence cystoscopy is being investigated as a new diagnostic tool for the detection of flat urothelial malignancies in bladder cancers. However, the influence of the bladder instillation time on the performance of this dete ...
A sizable fraction of T cells expressing the NK cell marker NK1.1 (NKT cells) bear a very conserved TCR, characterized by homologous invariant (inv.) TCR V alpha 24-J alpha Q and V alpha 14-J alpha 18 rearrangements in humans and mice, respectively, and ar ...
B cells undergo a complex series of maturation and selection steps in the bone marrow and spleen during differentiation into mature immune effector cells. The tumor necrosis factor (TNF) family member B cell activating factor of the TNF family (BAFF) (BLyS ...
Changes in sample concentrations of CO2 or organic acids cause potential instabilities when polymer membranes are directly applied to the surface of ion-selective field-effect transistors (ISFETs). Currently used designs avoid this well-documented effect b ...
