Abstract: A positive electrode slurry composition, a positive electrode and a secondary battery including the same are disclosed herein. In some embodiments, a slurry composition includes a lithium iron phosphate-based positive electrode active material, a binder, a conductive agent, a dispersant, and a solvent, wherein the dispersant includes a nitrile-based copolymer and a polymer dispersant containing an oxyalkylene unit, wherein the oxyalkylene unit is present in an amount of 60 wt% or more, based on the total weight of the polymer dispersant.

Abstract: The present application relates to an antibacterial composition. The present application can provide an antibacterial composition that has no hazardousness to the human body and exhibits antibacterial characteristics against various microorganisms or bacteria. The antibacterial composition can exhibit excellent antibacterial properties against so-called super bacteria.

Abstract: A semiconductor device includes a substrate including a conductive region, an insulating layer disposed on the substrate and including an opening exposing the conductive region, and a conductive layer buried within the opening and including a first region disposed on inner side walls of the opening and a second region disposed within the first region. The first region includes a plurality of first crystal grains and the second region includes a plurality of second crystal grains. The pluralities of first and second crystal grains are separated from each other at a boundary formed between the first and second regions.
