Aim of the Work

The following examples illustrate the application of high-throughput screening tools together with heuristic search algorithms in the development of new enhanced catalyst for two fields of industrial interest, olefin epoxidation and the isomerization of light paraffins. 

Catalyst preparation and activation conditions are included as parameters of importance in the optimisation algorithm. The preparation and activation procedures are very relevant aspects since minor variations in such conditions would cause major changes to the final phase of the solid and, consequently, to its catalytic properties. Typical preparation variables are promoter precursors, type of impregnation, calcination atmosphere, time and temperature, time and temperature for metal reduction and so forth.

The aim of the work we present in this paper is to optimize the control parameters used in particles magnetic and interpret the obtained results. Experiments are performed on samples of welds or materials containing known defects. The realized and tested defects are grooves situated at different depths with variables dimensions. Other types of defects have been studied (inclusions, lack of penetration, etc.). 

Unloaded silica does not recover HPA from aqueous solution. The surface of silica gel modified with quarternary ammonium salts (QAS) gets anion-exchange properties. The aim of the work is the elaboration of solid-phase reagents on the base of ion associate of HPA with QAS immobilized onto silica surface for the determination of phosphoms and organic reductants. Heterocyclic (safranine and lucigenine) and aliphatic (trinonyloctadecyl ammonium iodide and tetradecyl ammonium nitrate) compounds have been examined as QAS. 

The aim of the work is investigate possibilities of application of Cartridges Packed DIAPAK for concentrating antibiotics Cefazoline and Levomycetine and analyze them by Reversed Phase High Performance Liquid Chromatography (RP HPLC). 

BP Chemicals studied the use of chloroaluminates as acidic catalysts and solvents for aromatic hydrocarbon allcylation [41]. At present, the existing AICI3 technology (based on red oil catalyst) is still used industrially, but continues to suffer from poor catalyst separation and recycling [42]. The aim of the work was to evaluate the AlCl3-based ionic liquids, with the emphasis placed on the development of a clean... 

The aim of the work was the development of a technique to deposit enzyme LB films on the surface of small glass spheres and to test the enzymatic activity of such samples before and after thermal treatment.

The aim of the work was evaluation of the ability of photoexcited fullerene C60 and synthesized fullerene C60-containing composites to generate reactive oxygen species (ROS) and to perform comparative analysis of the state of the cells of two types (normal ones - thymocytes, and malignant ones - the cells of ascite Erhch carcinoma [EAC] and leucosis L1210) by such indexes as viability, content of LPO products, MTT test, and DNA fragmentation upon incubation in the presence of photoexcited fullerene C60. 

We studied the feasibility of phosphate determination in a low water-soluble API hydrochloride salt. The aim of the work was quantification of phosphate below 0.1% and evaluation of the effect of the high chloride counterion on the determination of phosphate. 

One of the aims of the work carried out in this laboratory was to investigate the deposition of trace elements on the hydrocracking catalyst. To this end, a continuous laboratory hydrocracker was installed and, to provide feed material for this, a 2-1 autoclave and pressure filter were also installed. It was noticed on the initial runs with the autoclave that the ash level of the filtered extract solution was considerably lower, at 100-200 ppm, than that normally obtained by British Coal, at 500-600 ppm. The reason for this difference was not known, so an investigation was carried out which found that the lower ash levels could be produced by a higher digestion pressure. Table 1 shows some of the results obtained, which have b n previously published (10). Note that throughout all the experiments described in this paper the coals used were Point of Ayr and Calverton, whose analyses are given in Table 2, and that the HAO to coal ratio us was always 2 1. Hence, ash analyses in the coal extract solution are comparable. 

However, I still think - despite these intrinsic difficulties - that it is important to debate the question of the detiitition of life, both from an intellectual and a practical point of view. Everyone working in the held of the origin of life should be able to provide their own definition (or description) of life, simply because they work experimentally or theoretically on models of minimal life and they should state and define the subject of the inquiry and the final aim of the work. This corresponds already to a kind of definition of life. Considering the number of authors in the held, this may correspond to quite a large number of different research projects, but all should adhere to the same basic constraints. What are these ... 

Boron has two isotopes, 10B (20%) and nB (80%), of which the former strongly absorbs neutrons to give a-particles according to equation (21). One aim of the work with boron heterocycles was to find nontoxic compounds, stable in the human body, for use in neutron capture therapy of cancer. It was hoped that boron-nitrogen analogues of benzene or pyridine should have derivatives with these properties, but no such compound has been found. 

The aim of the work under consideration was to correlate the effectiveness of the drag reduction with the molecular parameters of the polymer causing it. 

The aim of the work outlined below is to provide reference compounds of well-defined structures to be used in connection with the analysis of the... 

The aim of the work was to develop a methanol fuel processor for a 50 kW automobile engine. An integrated heat exchanger/reactor was fabricated and results were presented by Hermann et al. [120] of GM/OPEL. The specifications for the system were ambitious, amongst others ... 

In this application, the portable camera is capable of imaging motion over the full width of the fluidised bed but not the full height. Because the main aim of the work was to quantify circulation, it was decided to form the camera elements up into lower and upper banks, intended to follow the flows under and over the baffle, respectively. 

In an attempt to combine the two approaches of accelerating organic reactions, a nucleophilic substitution reaction has been carried out in a microemulsion in the presence of a phase transfer agent [51]. The aim of the work was to investigate if a combination of the two approaches would give a reaction rate higher than that obtained in either the microemulsion approach or in a two-phase system using phase transfer catalysis. 

As with alchemy in China, the underlying aim of the work is to free the alchemist from the constraints of time. While the materials are being worked on, the alchemist is still in the state of becoming. Mercury has to be fixed or killed (this is identified with the ego). The end of the work, in which the metals (and Nature — both nature in general and the alchemist s own nature) are perfected , sees the alchemist reach the state of pure being, in which there is no past or future, no further striving upwards, but an abiding state of clear, mindful existence. 

Reiss et have recently carried out an extensive theoretical study of the linear and nonlinear properties of pNA in the gas phase, of three solvents, cyclohexane (CH), 1,4-dioxane (DI) and tetrahydrofuran (THF) and of solutions of pNA in these solvents. The aim of the work is to provide a treatment in which the liquid phase molecules are treated discretely via a statistical simulation of the liquid and solution structures. The general strategy for attaining this goal can be summarized as follows -...
