The reactions of phosphorus pentoxide with two alcohols and one phenol were performed in different conditions under microwave irradiation. The products (alkylphosphates and dialkylphosphates) were identical to those formed by classic heating and were obtained with better yields. The speed of the reaction was increased by a factor from 100 to 4000.
The present invention relates to methods and systems for functionally stimulating or coupling neurons and neuron target cells to electronic circuits, which use a stimulating electrode and an ion selective zone adjacent the cell membrane of the cell to be stimulated which selectively absorbs and expels one or more stimulating ion species under control of the stimulating electrode. This changes the concentration of signal or response-controlling structures in the cell wall.
The invention relates to a radiation curable composition comprising radiation curable components wherein the composition comprises at least two flame retardants and wherein the flame retardants belong to different classes of compounds, to a process for making three dimensional flame retardant articles and to a three dimensional article, made by rapid prototyping means, that passes the flame retardancy UL-94-V0 test.
