Abstract: Disclosed is a method for predicting an elution order of compounds in a mixture. The method includes (a) building a quantitative structure-retention relationship (QSRR) model and (b) predicting a chromatographic elution order of the compounds in the mixture on the basis of the QSRR model using mathematical programming. The mathematical programming is a non-linear programming technique in which a predicted elution order of the compounds is used as a constraint or a multi-objective optimization (MOO) in which a retention time prediction error and an elution order prediction error are used as objective functions. With the use of the method of the present disclosure, it is possible to optimize separation of complex mixtures in reversed-phase chromatography by enabling identification of accurate positions of individual compounds that provides higher certainty in identifying a given compound, e.g., during an “omics” analysis (proteomics, metabolomics, etc.).

Abstract: A polymer solar cell including a cathode buffer layer (CBL) is proposed. the CBL may include a reaction product between a conjugate polymer electrolyte and an acid derivative, the conjugate polymer electrolyte is poly [(9,9-bis 3′-(N,N-dimethylamino) propyl)-2,7-fluorene)-alt-2,7-(9,9-dihexylfluorene)] (PFN), and the acid derivative is trifluoroacetic acid (CF3AA), 4-trifluoromethyl benzoic acid (CF3BA), or 4-toluene sulfonic acid (TsOH). The CBL including the conjugate polymer electrolyte (PFN) modified with a specific acid derivative may improve short-circuit current (Jsc) and a filling factor (FF) simultaneously, and thus, significantly improved efficiency is exhibited.

Abstract: This application relates to an apparatus and method for analyzing the damping characteristics of a carbon composite material. Damping analysis of carbon composite material using modal damping ratio is a conventional method that cannot accurately represent viscous damping coefficient variation but has errors in a sensitivity analysis. The damping characteristics of the carbon composite material were described by a parallel combination of the viscous damping coefficient of carbon fiber and binding matrix. The damping characteristics of the carbon composite material were expressed with the sensitivity index calculated only from the viscous damping coefficient of the carbon fiber by removing the viscous damping coefficient of the binding matrix that does not change depending on the carbon fiber direction. Various embodiments improve accuracy in analyzing the damping characteristics of carbon composite material.

Abstract: The present disclosure relates to a lateral flow immunoassay device with an increased detection signal intensity by applying a pressure to a membrane, and the lateral flow immunoassay device manufactured by applying the pressure to the membrane according to the present disclosure shows significantly higher sensitivity than that of a lateral flow immunoassay device without applying a pressure to the membrane. Accordingly, the present disclosure, as an invention that increases the detection signal intensity by a very simple physical method without the need for chemical treatment, is suitable for mass production and may obtain an effect of reducing costs without requiring the use of additional materials. Therefore, the present disclosure can be usefully used for a lateral flow immunoassay device for detecting various target materials.
