Abstract: Proposed is a precursor composition for forming a metal film including a zirconium compound represented by any one of Chemical Formulas 1 to 3 and a hafnium compound represented by any one of Chemical Formulas 4 to 6.

Abstract: A degassing apparatus for a secondary battery, and a degassing method using same, is provided. The degassing apparatus includes a drive motor and a jig arm configured to pressurize a first surface of a gas pocket of a battery cell and a second surface opposite the first surface by controlling a separation distance by the operation of a driving motor. The degassing apparatus is capable of performing an effective degassing and sealing process for the battery cell without positional movement of the battery cell during cell activation or after cell activation.

Abstract: The battery diagnosis method includes calculating, by a battery management system (BMS), a plurality of direct current internal resistances (DCIRs) respectively with respect to a plurality of battery cells based on a plurality of cell voltages and a plurality of cell currents, deriving, by the BMS, an entire representative value of the plurality of DCIRs, calculating, by the BMS, a multi-parallel ideality factor based on a parallel connection number, calculating, by the BMS, a dispersion of the plurality of DCIRs based on the plurality of DCIRs and the entire representative values of the plurality of DCIRs, calculating, by the BMS, an upper limit threshold value of a normal range, and deriving, by the BMS, the normal range based on the upper limit threshold value, and diagnosing a state of a battery pack including the plurality of battery cells according to the normal range.

Abstract: A pressing jig for removing gas generated in an activation process of a battery cell includes a plate-shaped lower plate on which the battery cell that has undergone the activation process is placed and fixed, and an upper plate that presses the battery cell placed on the lower plate from above. At least one of the upper plate or the lower plate has a structure in which n (n?3) separated sub-plates are assembled to form a single plate, and the sub-plates independently press the battery cell. The pressing jig can suppress trapping of internal gas by sequentially pressing the battery cell.

Abstract: Provided are a silicon nitride film etching composition, a method of etching a silicon nitride film using the same, and a manufacturing method of a semiconductor device. Specifically, a silicon nitride film may be stably etched with a high selection ratio relative to a silicon oxide film, and when the composition is applied to an etching process at a high temperature and a semiconductor manufacturing process, not only no precipitate occurs but also anomalous growth in which the thickness of the silicon oxide film is rather increased does not occur, thereby minimizing defects and reliability reduction.

Abstract: The present invention relates to a transdermal composition for dementia treatment containing donepezil as an active ingredient. The transdermal composition according to the present invention contains highly concentrated donepezil in a hydrophobic matrix, can continuously release the drug for a long time by having excellent long-term adhesion to the skin, and further exhibits consistently effective therapeutic effects over a long period of time by having a significantly improved skin penetration rate in comparison with conventional donepezil patches.

Abstract: The present invention includes a vanillyl alcohol-containing copolyoxalate copolymer (PVAX). The present invention also includes a PVAX microparticle comprising PVAX. In one aspect, the compositions of the invention can be used as a drug delivery system, an antioxidant or anti-inflammatory composition, a composition for preventing or treating ischemic disease, a composition for inhibiting the side effects of anticancer drugs, a contrast agent, and/or a composition for diagnosing ischemic disease.
