In this work, we report the transfer of alkyl bis- and tris(pyrazolyl)aluminates metalloligands to an electron-rich organotransition metal center. The 16-electron heterobimetallic complexes rhodium [Rh(COD){Al(Ph2pz)2Me2}] (3) [Rh(COD){Al(Ph2pz)3Me}] (4) were obtained by metathesis reaction sodium (1) tris(pyrazolyl)aluminate (2) with [RhCl(COD)]2. For 3, 1H 13C NMR in solution along DFT calcul...

The continuous casting tundish is the last metallurgical reactor where molten metal flows before solidifying in mold. A covering powder can be used for improving steel cleanliness; this case it named ‘active slag’. objective of work to evaluate, laboratory, effect three kinds powders on cleanliness a SAE 1055 modified - Ca-aluminate, Ca-Mg-aluminate, and an Al-silicate powder, analysing their i...

The desilication effects of aluminium sulphate and sodium aluminate on kraft bamboo pulp during the cooking process were investigated in this study. Furthermore, the residual aluminium ion concentration in the resulting black liquor was measured by inductively coupled plasma atomic emission spectrometry (ICP-AES) to evaluate the scaling properties of black liquor during the evaporation process....

A modified commercial (Setaram C80) calorimeter has been used to measure the isobaric volumetric heat capacities of concentrated alkaline sodium aluminate solutions at ionic strengths from (1 to 6) mol kg, with up

A significant improvement in the production of l-ribulose from inexpensive and commercially available starting materials, L-arabinose and sodium aluminate, is demonstrated. This has facilitated expeditious access to gram-scale quantities of L-ribulofuranoside derivatives.

background: introducing new endodontic cements should await comprehensive investigations and new formulations have to be tested in vivo before applying in human beings. so, the purpose of this study was to compare the biocompatibility of new endodontic cements, calcium aluminate α-aluminate cement (caac), calcium aluminate α-aluminate plus cement (caac plus), and a mixture of wollastonite and c...
