摘要： A display device includes semiconductor nanoparticles. An organic light emitting diode (“OLED”) display device includes the semiconductor nanoparticles, a semiconductor particle of the semiconductor nanoparticles including: a core including a compound semiconductor; and a shell surrounding the core. The shell includes a metal oxide (and/or metalloid oxide) having a bandgap of about 3.5 eV or more, and having a sum (ΔECB+ΔEVB) of a conduction band offset (ΔECB) with the compound semiconductor included in the core and a valence band offset (ΔEVB) with the compound semiconductor included in the core of about 3 eV or more.

摘要： The present invention relates to a method for production of ammonia, using an inorganic nanoparticle-microbial complex in which a nitrogen fixation reaction in a microorganism is improved by increasing the amount of inorganic nanoparticles entrapped in the microorganism. The present invention can produce ammonia at low temperature and low pressure conditions, compared to the conventional Haber-Bosch process of producing ammonia in high temperature and high pressure conditions and in a friendly environmental manner without emission of carbon dioxide that is released during conventional chemical synthesis processes, whereby the present invention may be a competitive alternative to the prior art for production of ammonia that has an unlimited potential as a future energy resource.

摘要： Disclosed are inorganic nanoparticle quantum dots that effectively kill Gram-positive and Gram-negative bacteria resistant to antibiotics and the treatment of infectious bacterial diseases using the same, and more particularly inorganic nanoparticle quantum dots introduced with a hydrophilic ligand having activity of killing multidrug-resistant bacteria (MDR) and the use thereof. The quantum dots are capable of effectively killing bacteria when used at a low concentration by optimizing the core bandgap thereof and also do not exhibit cytotoxicity, and are thus useful as an agent for preventing or treating infectious diseases caused by multidrug-resistant bacteria.
