Abstract: Disclosed is a biomarker composition for diagnosing the toxicity of nanoparticles, which shows a change in expression by exposure to the nanoparticles, the biomarker composition comprising at least one gene selected from the group consisting of aldehyde dehydrogenase, glutamic-pyruvate transaminase, glutamate dehydrogenase, glutamicoxaloacetic transaminase, glutamic acid decarboxylase and glutamate-ammonia ligase, and to a method for evaluating the toxicity of nanoparticles using the same. The biomarker is a gene marker having a high correlation with the toxicity of nanoparticles, and the use of the biomarker can determine whether nanoparticles have toxicity, with high detection sensitivity. Also, the method is useful in monitoring or evaluating the toxicity of nanoparticles by analyzing factors having a high correlation with toxicity of nanoparticles.

Abstract: Disclose is a method and system for sharing search result using messenger. A messenger client generates search request information and receives web page data corresponding to the search request information. A search server receives the search request information from the messenger client and performs a search for one or more keywords included in the search request information to transmit search result page data to the messenger client. When the search result page is transmitted from the search server, a layer coupled to a conversation window is formed to display the search result page and allow users to share the information on web page corresponding to the search results when requested.

Abstract: A control arm may be formed by assembling front and rear members respectively having upper and lower flanges so as to have a tubular cross-section, and a bending portion may be formed by bending the lower flange of the front member downwardly such that a drain hole is formed by the bending portion protruded downwardly when the front and rear members are assembled.

Abstract: There is provided a surface cleaning apparatus and method using plasma to remove a native oxide layer, a chemical oxide layer, and a damaged portion from a silicon substrate surface, and contaminants from a metal surface. A mixture of H2 and N2 gas is used as a first processing gas. By absorbing potential in a grounded grid or baffle between a plasma generator and a substrate, only radicals are passed to the substrate, and HF gas is used as a second processing gas. Thus a native oxide layer, a chemical oxide layer, or a damaged portion formed on the silicon substrate during etching is removed in annealing step with H2 flow. The environment of a chamber is maintained constant by introducing a conditioning gas after each wafer process. Therefore, process repeatability is improved.

Abstract: Field effect transistors (FETs) include an integrated circuit substrate having a surface, and a gate on the surface. A pair of recessed regions in the substrate are located beneath the surface. Respective ones of the recessed regions are located on respective opposite sides of the gate. Each of the recessed regions define a sidewall and a floor. An elevated source/drain structure on each of the recessed regions is at least as thick adjacent to the gate as remote from the gate. A gate spacer may be included between the gate and the elevated source/drain region. The gate spacer can comprise an insulating film. Preferably, the source/drain structure extends to the sidewall of the recessed region. The elevated source/drain structure is preferably free of a facet adjacent the gate. The present invention also relates to methods for fabricating a field effect transistors (FET) having an elevated source/drain structure.
