Block Face Scanning Electron Microscopy of Fluorescently Labeled Axons Without Using Near Infra-Red Branding

In this article, we describe the method that allows fluorescently tagged structures such as axons to be targeted for electron microscopy (EM) analysis without the need to convert their labels into electron dense stains, introduce any fiducial marks, or ima ...

Composite hydrogel-loaded alumina membranes for nanofluidic molecular filtration

Jürgen Brugger, Philippe Renaud, Arnaud Bertsch, Fabien Patrick Wildhaber, Songmei Wu, Thomas Michael Braschler, Rebekka Anker

In this paper a nanofluidic molecular filtration system based on soft alginate hydrogel fillings and a solid-state alumina support membrane is presented. The electrostatically controlled diffusion is characterized by partition coefficient of the hydrogel a ...

Carbon-Doped TiO2 and Carbon, Tungsten-Codoped TiO2 through Sol-Gel Processes in the Presence of Melamine Borate: Reflections through Photocatalysis

Ravindranathan Thampi, Michael Jon Mattle

A series of C-doped, W-doped, and C,W-codoped TiO2 samples have been prepared using modified sol-gel techniques. Reproducible inexpensive C-doping arises from the presence of melamine borate in a sol-gel mixture, whereas W-doping is from the addition of tu ...

Phenoxazine Dyes for Dye-Sensitized Solar Cells and Relationship Between Molecular Structure and Electron Lifetime

Xiaoqing Jiang, Ulf Anders Hagfeldt

Metal-free org. dyes with a core phenoxazine chromophore have been synthesized and tested as sensitizers in dye-sensitized solar cells. Overall conversion efficiencies of 6.03-7.40% were reached under std. AM 1.5 G illumination at a light intensity of 100 ...

Partial oxidation of benzene catalyzed by heteropoly compounds

Albert Renken, Igor Iouranov, Benoît Louis

V substituted phosphomolybdic acids could hydroxylate benzene with nearly 100% selectivity at appreciable conversion levels in the presence of oxidizing agents like H2O2 and AcOOH. There appears to be a correlation, for the liq. phase, between phenol yield ...
