| 1 | Highly ordered lead-free double perovskite halides by design显示文摘Lead-free double perovskite halides are emerging optoelectronic materials that are alternatives to leadbased perovskite halides.Recently,single-crystalline double perovskite halides were synthesized,and their intriguing functional properties were demonstrated.Despite such pioneering works,lead-free double perovskite halides with better crystallinity are still in demand for applications to novel optoelectronic devices.Here,we realized highly crystalline Cs2AgBiBr6 single crystals with a well-defined atomic ordering on the microscopic scale.We avoided the formation of Ag vacancies and the subsequent secondary Cs3Bi2Br9 by manipulating the initial chemical environments in hydrothermal synthesis.The suppression of Ag vacancies allows us to reduce the trap density in the as-grown crystals and to enhance the carrier mobility further.Our design strategy is applicable for fabricating other lead-free halide materials with high crystallinity. | Chang Won Ahn Jae Hun Jo Jong Chan Kim Hamid Ullah Sangkyun Ryu Younghun Hwang Jin San Choi Jongmin Lee Sanghan Lee Hyoungjeen Jeen Young-Han Shin Hu Young Jeong Ill Won Kim Tae Heon Kim | 2020 | Journal of Materiomics2020，6，4： | 2 |

| 5 | Characterizations of organic compounds in diesel exhaust particulates显示文摘To characterize how the speed and load of a medium-duty diesel engine affected the organic compounds in diesel particle matter(PM) below 1 μm, four driving conditions were examined. At all four driving conditions, concentration of identifiable organic compounds in PM ultrafine(34–94 nm) and accumulation(94–1000 nm) modes ranged from 2.9 to 5.7 μg/m3 and 9.5 to 16.4 μg/m3, respectively. As a function of driving conditions, the non-oxygencontaining organics exhibited a reversed concentration trend to the oxygen-containing organics. The identified organic compounds were classified into eleven classes: alkanes,alkenes, alkynes, aromatic hydrocarbons, carboxylic acids, esters, ketones, alcohols, ethers,nitrogen-containing compounds, and sulfur-containing compounds. At all driving conditions,alkane class consistently showed the highest concentration(8.3 to 18.0 μg/m3) followed by carboxylic acid, esters, ketones and alcohols. Twelve polycyclic aromatic hydrocarbons(PAHs)were identified with a total concentration ranging from 37.9 to 174.8 ng/m3. In addition, nine nitrogen-containing polycyclic aromatic compounds(NPACs) were identified with a total concentration ranging from 7.0 to 10.3 ng/m3. The most abundant PAH(phenanthrene)and NPACs(7,8-benzoquinoline and 3-nitrophenanthrene) comprise a similar molecular(3 aromatic-ring) structure under the highest engine speed and engine load. | Jaehyun Lim Cheolsoo Lim Sangkyun Kim Jihyung Hong | 2015 | Journal of Environmental Sciences2015，27，8： | 1 |
