A new enantioselective synthesis of alpha- amino acids are described in which the key step is the enantioselective reduction of E, and Z furyl ketone oxime ethers with chiral boron complexes. The chirality of amino acid is fully controlled by appropriate choice of geometrical isomer of the oxime ether.

A GRAIN MODEL FOR CATALYST TORTUOSITY
Doğu, Timur (Informa UK Limited, 1991-01-01)
A simple model was proposed for the prediction of tortuosity factor of porous solids with mono or bidispersed pore size distributions. Model predictions were presented in graphical form for quick estimation of tortuosity. The experimental tortuosity factors reported in the literature for porous solids of different pore structures and the corresponding predicted values showed good agreement.
AN EMPIRICAL VIRIAL-LIKE CUBIC EQUATION OF STATE FOR PHASE EQUILIBRIUM CALCULATIONS
Orbey, H; Orbey, N (Informa UK Limited, 1990-4)
An empirical cubic equation of state(EOS) was obtained by truncating the virial expansion in reciprocal of molar volume after the third term. The constants of the EOS was generalized in terms of critical temperature, critical pressure and Pitzer's acentric factor. In pure component applications the EOS exhibited a performance comparable to Peng-Robinson (1976) EOS in the reduced temperature range of 0.5 to 1. The present EOS tends to predict better saturation liquid volumes at reduced temperatures below 0....
A new method for processing of monazite and examination of the products by X-ray analysis
Kizilyalli, Meral; Welch, Alastair J. (Elsevier BV, 1987-1)
Sintering reactions of lanthanide orthophosphates with Na2CO3 gave the expected products (Na3PO4 and Ln2O3) with stoichiometric amounts of Na2CO3. When less than the theoretical amounts of Na2CO3 were used, two intermediate products eventually characterized by X-ray diffraction as Na3Ln(PO4)2 and Ln3PO7 were detected. Application of the sintering method to naturally occurring phosphates, particularly the mineral monazite, proved to be very successful. By using the optimum amount of Na2CO3 to form Na3Ln(PO4)...
AN EXPERIMENTAL INVESTIGATION OF POLYVINYL-CHLORIDE) EMULSION POLYMERIZATION - EFFECT OF INITIATOR AND EMULSIFIER CONCENTRATIONS ON POLYMERIZATION KINETICS AND PRODUCT PARTICLE-SIZE
Karakaş, Gürkan (Wiley, 1989-01-01)
Effects of concentration changes in initiator species Na2SO3, (NH4)2S2O8 and CuSO4, and emulsifier, ammonium stearate, on poly(vinyl chloride) (PVC) emulsion polymerization kinetics and on product particle size were experimentally investigated. It was observed that to obtain industrially significant rates and overall conversions, not only an optimum concentration ratio of Na2SO3/(NH4)2S2O8/CuSO 4 must be used, but also the concentrations of these species must be above certain limits. Increasing the concentr...
Synthesis and enhanced photocatalytic activity of nitrogen-doped triphasic TiO2 nanoparticles
Erdogan, Nursev; Bouziani, Asmae; PARK, JONGEE; Micusik, Matej; Kim, Soo Young; Majkova, Eva; Omastova, Maria; Öztürk, Abdullah (Elsevier BV, 2019-05-15)
TiO2 nanoparticles of the single anatase phase, binary anatase-brookite phases, and ternary anatase-brookite-rutile phases were synthesized using an HNO3-catalyzed hydrothermal process. The types and amounts of phases varied depending on the hydrothermal synthesis conditions. The results revealed that N dissolves in different amounts and chemical states, depending on the phases present and their proportions in the nano particles. Brookite and rutile nanoparticles oriented through one direction were found to...
