Abstract: A mask and a controlling method thereof are disclosed. The mask includes a fan that provides an air volume to an inside of the mask, a valve that discharges air from the mask, a pressure sensor, and a processor. The processor may control the pressure sensor to detect a maximum pressure value and a minimum pressure value inside the mask worn by a user. The processor may identify a time for a single breath based on a maximum pressure value and a minimum pressure value detected at the pressure sensor. The processor may identify a number of breaths based on the identified time for the single breath and a predetermined time. The processor may control the fan to provide an air volume set at a level corresponding to the identified number of breaths among a plurality of levels divided based on a predetermined number of breaths.

Abstract: A lithium secondary battery, specifically, a lithium secondary battery. By specifically adjusting the porosity (%) and the mass of sulfur per unit area (mg/cm2) of a positive electrode active material layer including a sulfur-carbon composite, the initial battery discharge capacity is improved, and thus a high energy density can be achieved.

Abstract: A sulfur-carbon composite for controlling the particle size of the sulfur-carbon composite to a specific range and a method for preparing the same.

Abstract: The invention provides a drug delivery system for a combination of therapeutic agents. The system includes a water soluble biodegradable ABA-type triblock copolymer that possesses thermosensitive gelation properties. The system can form a stable thermogel that includes a combination of therapeutic agents including, for example, rapamycin, paclitaxel, and 17-AAG. After administration to a subject, the drugs are released at a controlled rate from the thermogel, which biodegrades into non-toxic components. The polymer system can also function to increase the solubility and stability of drugs in the composition.

Abstract: The invention provides biocompatible micelles loaded with one or more active agents. The micelles can encapsulate anticancer drugs such as gossypol, and combinations of drugs, such as gossypol and paclitaxel, gossypol and 17-AAG, gossypol and cyclopamine, gossypol, paclitaxel, and 17-AAG, and gossypol, paclitaxel, and cyclopamine. The micelle compositions provide effective solubilization of difficult to solubilize drug combinations without the need for additional surfactants that can be toxic to patients. Thus, the invention provides stable and biocompatible drug formulations that improve bioavailability without causing toxicity.
