Estimating the Fraction Dose Absorbed from Suspensions of Poorly Soluble Compounds in Humans: A Mathematical Model
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1993-02)
A microscopic mass balance approach has been developed to predict the fraction dose absorbed of suspensions of poorly soluble compounds. The mathematical model includes four fundamental di-mensionless parameters to estimate ...
Photocatalytic membrane of a novel high surface area TiO 2 synthesized from titanium triisopropanolamine precursor
(John Wiley & Sons, Ltd., 2006-08)
Photocatalytic membrane was successfully prepared using an efficiently high surface area TiO 2 catalyst, dispersed into polyacrylonitrile matrix. The catalyst was directly synthesized using titanium triisopropanolamine ...
Protein release from Escherichia coli cells permeabilized with guanidine–HCl and Triton X100
(Wiley Subscription Services, Inc., A Wiley Company, 1989-02-20)
An important factor complicating the recovery of recombinant proteins from Escherichia coli is their intracellular location. An alternative to the commonly used method of releasing these proteins by mechanical disruption ...
Carbon-hydrogen bond activation over tungsten carbide catalysts
(Elsevier, 1994-08-30)
Tungsten carbides with surface areas ranging from 4 to 39 m2/g were prepared by the temperature-programmed carburization of tungsten oxide and nitride powders with pure CH4 or a 48.9% CH4 in H2 mixture. Oxygen uptakes on ...
Interfacial segregation in Ag-Au, Au-Pd, and Cu-Ni alloys: I. (100) surfaces
(Kluwer Academic Publishers; Springer Science+Business Media, 1993-03)
Atomistic simulations of segregation to (100) free surface in Ag−Au, Au−Pd, and Cu−Ni alloy systems have been performed for a wide range of temperatures and compositions within the solid solution region of these alloy phase ...
High resolution laser spectroscopy of relaxation and the excitation lineshape of excitons in GaAs quantum well structures
(Elsevier, 1990-04-01)
A new class of measurements on GaAs quantum well structures based on frequency domain nonlinear laser spectroscopy is described. Room temperature measurements of the excitation relaxation show an interference effect in the ...
Model-based analysis and design of a microchannel reactor for tissue engineering
(Wiley Subscription Services, Inc., A Wiley Company, 2006-06-20)
Recently developed perfusion micro-bioreactors offer the promise of more physiologic in vitro systems for tissue engineering. Successful application of such bioreactors will require a method to characterize the bioreactor ...
Interfacial segregation in Ag-Au, Au-Pd, and Cu-Ni alloys: II. [001] Σ5 twist grain boundaries
(Kluwer Academic Publishers; Springer Science+Business Media, 1993-03)
Atomistic simulations of segregation to [001] Σ5 twist boundaries in Cu−Ni, Au−Pd, and Ag−Au alloy systems have been performed for a wide range of temperatures and compositions within the solid solution region of these ...
The Synthesis of Brominated Tetrafluoro[2.2]paracyclophanes Dedicated to Professor Henning Hopf
(WILEY-VCH Verlag, 2006-12)
The bromination of the two isomeric tetrafluoro[2.2]paracyclophanes was investigated under various conditions.We found selective conditions for mono- and dibrominationof 1,1,9,9-tetrafluoro[2.2]paracyclophane in high yields. ...
Characterization of HDS/HDN active sites in cluster-derived and conventionally-prepared sulfide catalysts
(Elsevier, 1994-08-30)
The catalytic and sorptive properties of a series of sulfide cluster-derived catalysts were compared to those of an analogous series of conventionally-prepared sulfides. The cluster-derived and conventionally-prepared ...
