Surface characteristics of acrylic modified polysulfone membranes improves renal proximal tubule cell adhesion and spreading

Current polyvinylpyrrolidone-modified polysulfone (PVP-PSU) membranes in haemodialysers do not facilitate the attachment and proliferation of renal proximal tubule cells (RPTCs) For bioartificial kidney (BAK) development expensive extracellular matrices ar ...

Dark curing kinetics of UV printing inks by real-time ATR-FTIR spectroscopy

Eric Jacques Nouzille

In UV-curable printing technology, an ink or a varnish is exposed to the UV-light source within a fraction of a second. Subsequent polymerization therefore proceeds in the dark, referred to as dark curing. Because dark curing can be critical and contribute ...

Membrane reactor microstructured by filamentous catalyst

Albert Renken, Lioubov Kiwi, Olivier Wolfrath

A novel design of microstructured membrane reactor with micro-channels formed between closely packed catalytic filaments is reported. The system comprises filaments of 7 mm in diam. and has a laminar flow with a short radial diffusion time. This leads to l ...

About the stereoelectronics of the intramolecular addition of allylsilanes to aldehydes

Christophe Bauer

(Z)-omega-Trimethylsilyl-(omega-2)-alken-1-ols are readily accessible by consecutive superbase metalation and silylation of (omega-1)-alken-1-ols. These versatile intermediates may be oxidized to give the corresponding (Z)-omega-trimethylsilyl-(omega-2)-al ...

Total synthesis of a protected form of 2,6-anhydro-5-azido-3,5-dideoxy-2-C-hydroxymethyl-L-allo-heptose; a potential precursor of analogs of C-glycosides of neuraminic acid

Pierre Vogel

The title aldehyde (-)-3 and its enantiomer (+)-3 have been prepared starting from furfuryl alcohol and acetone. The method involves the diastereoselective [4+3]-cycloaddition of 2-[(benzyloxy)methyl]furan and 1, 3-dibromo-2-oxyallyl cation giving adduct ( ...

Preparation of methanolic formaldehyde

Albert Renken

Methanolic HCHO, essentially H2O-free, is prepd. by dehydrogenation of MeOH over a catalyst contg. >=1 Na compd. at 300-800 Deg. Thus, a mixt. contg. 13% MeOH and 87% N was passed at 700 Deg and 0.154 mol/h over a catalyst prepd. by sintering Na2B4O7 and I ...

Process and dehydrogenation catalysts for the production of formaldehyde from methanol

Albert Renken

HCHO is prepd. in high yield and selectivity by the dehydrogenation of MeOH in the presence of catalysts contg. metallic Na or >=1 Na compd. at 300-800 Deg. Na2CO3 was heated under H at 5 Deg/min and the temp. maintained during this heating process at 100 ...

New catalysts for the dehydrogenation of methanol to water-free formaldehyde

Albert Renken

Some Na compds. are selective catalysts for dehydrogenation of MeOH to HCHO, stable under high temps., and not reduced by H which is formed. They undergo some deactivation due to coking, but burning the coke easily returns the catalyst to its initial activ ...
