The present invention relates to an oxygen generating scaffold including a polydimethyl siloxane (PDMS)-CaO2 ring structure and a polycaprolactone PCL film and a manufacturing method thereof. According to the present invention, the oxygen generating scaffold is capable of preventing a loss of the function of an islet cell, caused by the necrosis and apoptosis that occurs when oxygen is abnormally circulating due to islet encapsulation, and improving the survivability of islet and glucose-stimulated insulin secretion. Moreover, the present invention is capable of having a simple system and preventing an external obliteration of islet by injecting islet through a lateral surface, thereby having a low risk. As such, the scaffold is able to be widely applied in biomedical technology fields including the treatment of diabetes with a bioartificial islet. COPYRIGHT KIPO 2018 ...

The present invention relates to a method for removing an organic acid from crude oil by using gas hydrate formation inhibitors and a catalyst in an oil production facility or oil refinery facility, and more particularly, to a method for removing an organic acid from crude oil by reacting mono-ethylene glycol (MEG), di-ethylene glycol (DEG), tri-ethylene glycol (TEG), and methanol, or their derivatives, i.e., gas hydrate formation inhibitors, with crude oil in the presence of a tungstophosphoric acid (TPA), i.e., a catalyst. According to the present invention, acidity of crude oil can be decreased by 93 % or more, a problem of inactivating the catalyst does not occur since a magnesium (Mg)-based catalyst is not used, and a continuous process of recovering the gas hydrate formation inhibitors and the catalyst from the crude oil, from which the organic acid has been removed, and reusing them to remove the organic acid from the crude oil can be implemented, thereby providing an effect of removing ...

The present invention relates to an oxygen-generating scaffold comprising a polydimethylsiloxane (PDMS)-CaO2 ring structure and a polycaprolactone (PCL) membrane and a method of producing the same. Using the oxygen-generating scaffold according to the present invention makes it possible to overcome the loss of function of islet cells due to apoptosis and necrosis that are caused by insufficient oxygen supply due to encapsulation of islets, and to enhance the survival rate of islets and insulin secretion function with respect to glucose stimulation. In addition, the system is simple, and the risks are relatively low since the external loss of islets can be prevented by injecting the islets through a side thereof. Therefore, the present invention can be widely used in biomedical technology fields such as diabetes treatment using bioartificial islets.
