MOCVD of rhodium, palladium and platinum complexes on fluidized divided substrates: Novel process for one-step preparation of noble-metal catalysts
(John Wiley & Sons, Ltd., 1998-03)
A new one-step method, entitled fluidized-bed metal-organic chemical vapor deposition (FBMOCVD) of preparing highly dispersed metal-supported catalysts is reported. The following complexes were studied and used as CVD ...
TECHNICAL REPORT: Rapid confirmation of gene targeting in embryonic stem cells using two long-range PCR techniques
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1998-03)
Gene targeting in mouse embryonic stem (ES) cells generally includes the analysis of numerous colonies to identify a few with mutations resulting from homologous recombination with a targeting vector. Thus, simple and ...
Chemical permeabilization and in situ removal of daidzein from biologically viable soybean (Glycine max) seeds
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1998-09)
After 24 h of chemical permeabilization with 20% (v/v) methanol at 25 °C, the amount of daidzein released from soybean seeds is 15 to 20% of the amount (0.0423 ± 0.0045 mg/g seed dry wt) obtained by physical grinding. With ...
Second-generation polymeric precursors for BN and SiNCB ceramic materials
(John Wiley & Sons, Ltd., 1998-10)
Our recent work directed at the design, synthesis, characterization and applications of new types of polyborazylene and polyborosilazane polymers is reviewed with a focus on the use of these polymers as processable precursors ...
Dual role for the zeste-white3/shaggy -encoded kinase in mesoderm and heart development of Drosophila
(John Wiley & Sons, Inc., 1998)
A Drosophila homolog of the serine/threonine kinase GSK-3β, encoded by the zest-white3/shaggy gene ( zw3 ), has been implicated as a maternally provided antagonist of zygotic signaling by the secreted segmentation gene ...
Synthesis of block, graft and star polymers from inorganic macroinitiators
(John Wiley & Sons, Ltd., 1998-10)
Recent advances in the synthesis of block, graft and star polymers containing inorganic macromolecular species are described. Anionic copolymerization techniques were used in the for-mation of diblock copolymers of ...
Comparison of SnBr 4 and di-n-butyl tin diacetate as laser-assisted chemical vapor deposition precursors for SnO 2 -based gas sensors
(John Wiley & Sons, Ltd., 1998-03)
Laser-assisted chemical vapor deposition (LCVD) was utilized to produce SnO 2 films from SnBr 4 plus air, O 2 or N 2 O. SnO 2 films were successfully generated using either 222 or 308 14nm laser pulses but there was ...
Elemental balancing of biomass and medium composition enhances growth capacity in high-density Chlorella vulgaris cultures
(Wiley Subscription Services, Inc., A Wiley Company, 1998-09-05)
The basic requirements for high-density photoautotrophic microalgal cultures in enclosed photobioreactors are a powerful light source and proper distribution of light, efficient gas exchange, and suitable medium composition. ...
Impact of a Simple Inexpensive Quality Assurance Effort on Physician's Choice of Thrombolytic Agents and Door-to-Needle Time: Implication for Costs of Management
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-01)
The objective of this study were to assess the impact of a quality assurance effort on the door-to-needle time and the choice of thrombolytic agent for the management of acute myocardial infarction in the emergency department. ...
Vacancy Generation During Grain Boundary Migration
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-12)
We present a molecular dynamics simulation study of vacancy generation and emission from grain boundaries during curvature-driven grain boundary migration. The U-shaped half-loop bicrystal geometry is employed in order to ...
