20090020807 | SEMICONDUCTOR DEVICE AND METHOD FOR FABRICATING THE SAME - Disclosed are a semiconductor device and a method for fabrication of the same. The fabrication method may include selectively forming an oxide layer pattern on a semiconductor substrate, forming an insulation layer pattern on the same substrate to cover edge portions of the oxide layer pattern, etching the oxide layer pattern and the substrate to form a recess as well as first and second oxide layer patterns corresponding to the edge portions of the oxide layer pattern, forming a third oxide layer pattern on the substrate in the recess to produce a gate insulation layer comprising the first, second, and third oxide layer patterns, and forming a gate pattern in the recess. The fabricated semiconductor device minimizes occurrence of current leakage such as gate induction drain leakage, among other things, thereby improving transistor performance. | 01-22-2009 |
20100292261 | QUORUM SENSING ANTAGONIST, METHOD OF PREVENTING A BIOFILM FORMATION USING THE QUORUM SENSING ANTAGONIST AND METHOD OF REDUCING A BACTERIAL CONTAMINATION USING THE QUORUM SENSING ANTAGONIST - In the quorum sensing antagonist blocking the communication in bacteria, the method for preventing biofilm formation using this quorum sensing antagonist and the method for reducing the bacterial contamination, the quorum sensing antagonist contains the homoserine lactone moiety and sulfanylethanoyl group, and has a similar chemical structure to that of the autoinducer which is produced by bacteria as a signal, whereby the quorum sensing antagonist can inhibit the formation of biofilm and reduce the bacterial contamination as well. | 11-18-2010 |
20150129433 | METHOD FOR RECOVERING A METAL FROM SOLUTION, SYSTEM FOR RECOVERING A METAL FROM SOLUTION, AND SYSTEM FOR RECOVERING LITHIUM FROM SALT WATER - In a method for recovering a metal from a solution, a first electrode that includes a metal for recovery and a second electrode that includes a metal different from the metal for recovery are prepared. The first electrode and the second electrode are immersed in a first solution that includes a metal ion for recovery. The metal ion for recovery in the first solution is combined with the first electrode. The first electrode and the second electrode are charged while immersing the first and second electrodes in a second solution different from the first solution so that the metal ion for recovery is separated from the first electrode. The metal for recovery is recovered from the second solution. | 05-14-2015 |
