By means of potentiometric and calorimetric titrations, the complex formation of Co'+ and Cu*+ with different crown ethers has been studied in propylene carbonate. 1X5-crown ethers form the most stable complexes with both cations. The reaction enthalpies and entropies measured for the complexation...
By means of potentiometric and calorimetric titrations, the complex formation of Co 2+ and Cu 2+ with different crown ethers has been studied in propylene carbonate. 15C5-crown ethers form the most stable complexes with both cations. The reaction enthalpies and entropies measured for the ...
reaction of propoxylated bisphenol A fumarate unsaturated polyester continued after the completion of the ionic bond formation at the zinc oxide interface. It has been shown that the application of ultrathin polymer layers from dilute solutions can improve the wet adhesion strength.14,15,16Funke propo...
Redox transformations from soluble uranium (U) hexavalent species (U(VI)) to insoluble tetravalent species (U(IV)) largely constrain uranium biogeochemical behavior. This redox reaction occurs in the remediation of soils and sediments where biologically generated minerals may immobilize contaminant U1,2...
The reaction from DHBQ to RhA involves pentahydroxybenzene (PHB, I) as an intermediate which is either readily further oxidized to RhA by excess ClO2 or slowly reconverted to DHBQ in the absence of ClO2. The RhA yield after 30 min reaction time had a maximum of 83% at a DHBQ/ClO2 ...
surfactants, pH as one of the most important operating conditions and basic crude oil. Furthermore, Abbood et al. (2022) investigated the effect of another nanoparticle namely copper oxide (CuO) on the IFT reduction and wettability change in the existence of one imidazolium-based surfactant ...

In the reaction, it is also difficult to remove, after the reaction, a halogenic acid salt (a by-product) and purify the product; the production time is long; thus, the reaction is not favorable for industrial use. To avoid the formation of by-product in the above polymer reaction, ...
The present invention is directed to compositions of an islet cell differentiation transcription factor polypeptide, or any of its homologs or orthologs, as a therapeutic agent for the treatment of diabetes, more specifically insulin-dependent diabetes. The methods and compositions of the present inventi...
1. A method for producing bone ex vivo, comprising the steps of: a) obtaining an osteogenic cell or bone precursor cell; b) culturing said cell under serum free conditions in the presence of one or more osteogenic growth factors; and c) maintaining the cell cultures at cell densities that...
