A method for controlling a washing machine includes comparing a command value of a motor with a predetermined limit value, during spin-drying, to determine whether the motor is overloaded, and controlling driving of the motor in response to the determination. It may be possible to determine a water filling state, an excessive bubble state, or a drainage error state, which may be caused during a spin-drying operation, and to take a proper measure. That is, in the drainage error state, a user is informed of the drainage error. In the water filling state, the spin-drying is normally completed by re-performing the spin-drying operation. In the excessive bubble state, a rinsing or spin-drying operation is added to remove the bubbles. When the bubbles are not removed by the added rinsing or spin-drying operation, the excessive bubble message is displayed to inform a consumer of the excessive bubble state.

Methods for producing nanoparticle thin films are disclosed. According to one of the methods, a nanoparticle thin film is produced by modifying the surface of nanoparticles to allow the nanoparticles to be charged, controlling an electrostatic attractive force between the charged nanoparticles and a substrate and a repulsive force between the individual nanoparticles by a variation in pH to control the number density of the nanoparticles arranged on the substrate.

A light-emitting device including a semiconductor nanocrystal layer and a method for producing the light-emitting device are provided. The light-emitting device includes a semiconductor nanocrystal layer whose voids are filled with a filling material. According to the light-emitting device, since voids formed between nanocrystal particles of the semiconductor nanocrystal layer are filled with a filling material, the occurrence of a current leakage through the voids is minimized, which enables the device to have extended service life, high luminescence efficiency, and improved stability.

An organic electrolytic solution and a lithium battery employing the same are provided. The organic electrolytic solution includes a lithium salt, an organic solvent containing a first solvent having a high dielectric constant and a second solvent having a low boiling point, and a surfactant including a hydrophobic portion having an aromatic group. The organic electrolytic solution effectively prevents the electrolytic solution from contacting the anode, thereby suppressing side reactions on the anode surface and improving discharge capacity, charge/discharge efficiency, lifespan, and battery reliability.
