In particular, the cathode active material for a lithium secondary battery includes: a core part comprising a lithium metal oxide; and a coating layer covering at least a portion of a surface of the core part and comprising an inorganic compound.

Abstract: The present disclosure provides a smoking article filter which includes lyocell tow including lyocell fibers, a binder solution, and filter wrapping paper, and has 90% or higher biodegradation within 6 months according to the American Society for Testing and Materials (ASTM) D6691 under marine conditions at 30° C., and a smoking article including the smoking article filter.

Abstract: A cigarette filter which includes lyocell tow made of a plurality of lyocell fibers and a binder configured to bond the lyocell fibers to each other is provided. The cigarette filter according to one embodiment of the present disclosure reduces each of tar and nicotine, which are delivered through cigarette smoke, by 70% to 95%. The cigarette filter according to one embodiment of the present disclosure has a resistance to draw of 80 mmWG to 200 mmWG. The cigarette filter according to one embodiment of the present disclosure is filled with the lyocell tow at a packing density of 0.2 g/mL to 0.6 g/mL. The cigarette filter according to one embodiment of the present disclosure addresses basic material-related problems, such as low hardness, of the lyocell tow and, further, has excellent filtration functionality as a filter.

Abstract: The present disclosure relates to a system for cooling a stator core of an electric motor. The motor cooling system according to the present disclosure is advantageous in that the number of parts can be minimized, and cooling efficiency can be maximized with a cooling fluid evenly distributed to a heat-generating area, by improving a typical design (a core press-fit stop end) of a housing supporting the stator core to add a fluid guide and a nozzle shape or by applying a nozzle ring formed in a curved shape and capable of spraying the cooling fluid after being received and stored to an end of the housing.

Abstract: A display device includes a substrate, a semiconductor layer, an insulating layer, and a conductive layer. The semiconductor layer is disposed on the substrate, includes a channel of a first transistor, and includes a channel of a second transistor. The insulating layer is disposed on the semiconductor layer. The conductive layer is disposed on the insulating layer, includes a gate electrode of the first transistor, and includes a gate electrode of the second transistor. The channel of the first transistor includes a first first-element impurity ion and a second-element impurity ion different from the first first-element impurity ion. The channel of the second transistor includes a second first-element impurity ion identical to the first first-element impurity ion.

Abstract: A cavitation seed for drug delivery, and a drug delivery method using the same are disclosed. The cavitation seed according to the present invention comprises: a shell which forms the outer surface thereof to maintain the outer shape thereof within a fluid; and a core which is located inside the shell to determine buoyancy of the cavitation seed within the fluid. The cavitation seed can improve an effect of delivering a drug into a body since cavitation is induced by ultrasound at a position close to the epidermis. In addition, the cavitation seed can be applied in the delivery of various drugs as well as skin cosmetics, such as skin tone lightening agents, depilatories, hair restorers and skin fillers, skin analgesics, local anesthetics, agents for genetic diseases such as psoriasis, and agents for treatment of skin disease such as skin cancer.
