Zeolite A nanocrystals (100-240 nm) with well-developed crystal faces and uniform particle size distribution have been prepared at 80 degrees C for ca. 7.5 min in a two-phase liquid segmented microfluidic reactor using a manipulated organic template-free synthesis solution.

Herein, we report a rapid route for the synthesis of AlPO4-5. By combining fast heating in a tubular reactor with a seed-assisted method, both of which were found to be crucial, the preparation of AlPO4-5 was completed in one minute, making this route the fastest known for the preparation of the crystalline microporous materials.

We report the development of an automated chemical reactor for solid-phase synthesis of MIP NPs in water. Operational parameters are under computer control, requiring minimal operator intervention. In this study, "ready for use" MIP NPs with sub-nanomolar affinity are prepared against pepsin A, trypsin and α-amylase in only 4 hours.

Executive Summary The Clean Coal Technology (CCT) Program is a government and industry co-funded effort to demonstrate a new generation of innovative coal-utilization processes in a series of " showcase " facilities built across the country. These projects are carried out on a sufficiently large scale to prove commercial worthiness and generate data for design, construction, operation, and tech...

In this research, the thin films of N-S doped titanium dioxide (TiO2) were successfully prepared by simple sol-gel method in the presence of tetrabutylorthotitanate as a starting reagent. Furthermore, titanium dioxide (TiO2) was functionalized with thiourea. Furthermore, N-S doped titanium dioxides (NSTO) were fixed on glass balls by glass balls fixed-bed reactor system. Besides, the effect of ...

  Abstract : In this study, we prepared a LaNi0.3Al0.7O3 perovskite catalyst using a sol-gel related method (with prop ionic acid as a solvent) for use in the methane dry reforming reaction to produce synthesis gas. We defined the catalyst structure on the basis of X-ray diffraction analysis and measurements of the specific surface area and particle size distribution. The mixed oxide structure ...

A rapid flow synthesis of oxazolines and their oxidation to the corresponding oxazoles is reported. The oxazolines are prepared at room temperature in a stereospecific manner, with inversion of stereochemistry, from β-hydroxy amides using Deoxo-Fluor®. The corresponding oxazoles can then be obtained via a packed reactor containing commercial manganese dioxide.
