Abstract. An aerosol model optimized for northeast Asia is updated with the inversion data from Distributed Regional Aerosol Gridded Observation Networks (DRAGON)-northeast (NE) campaign which was conducted during spring March to May 2012. This then applied a single visible channel algorithm retrieve optical depth (AOD) Meteorological Imager (MI) on-board geostationary meteorological satellite, Communication, Ocean, and Satellite (COMS). plays an important role in retrieving accurate AOD...
CdSe quantum dots (QDs) were deposited on a p-type nanoporous NiO surface by repeating the successive ionic layer adsorption and reaction (SILAR) procedure from 6 to 15 cycles. All of QD-assembled films exhibited much better photoelectrochemical (PEC) performances than bare film. In particular, film with QD prepared 12 SILAR cycles significantly enhanced PEC response, due an effective light absorption in long wavelengths increased loading amount assembled QDs. However, as further up 15,...
Cu2-xS films in situ formed on brass substrates were annealed at different temperatures (100, 200, 300, and 400°C) flowing Ar gas, introduced as the counter electrodes (CEs) for CdSe quantum dot-sensitized solar cells (QD-SSCs). The QD-SSC with bare CE exhibited higher cell performance than that Pt CE. 300°C-annealed achieved best energy conversion efficiency of 4.25%, showing a 34% increase compared to This is because film 300°C provided rapid charge transport increased electrochemical...

This study assessed the distribution of microplastics (MPs) in gills, intestines, and muscles common carp (Cyprinus carpio), one main fish species consumed by humans living lower regions Han River South Korea. In total, 891 MP particles were detected 15 carps, with an average 59.4 ± 45.5 particles/specimen, indicating severe contamination. The predominant form was fragment (86%), size range 0.02–0.10 mm. Thirty muscle samples (n = 10), primarily sizes < 0.1 mm (89%). most types polymers...
CdSe quantum dots (QDs) were deposited on a p-type nanoporous NiO surface by repeating the successive ionic layer adsorption and reaction (SILAR) procedure 6, 9, 12, 15 times. The NiO/CdSe prepared using 12 SILAR cycles, which is denoted as NiO/CdSe(12), exhibited larger QD size better coverage than films with CdSe(6) CdSe(9), leading to light absorption over longer wavelengths significantly increased hole lifetime. resulting dot-sensitized solar cell (QD-SSC) enhanced efficiency (0.35%)...
Autonomous mobile robots are widely used for delivering food, drinks, and small goods. Because of their mobility, unmanned can move on roads, sidewalks, crosswalks. Even though most them paved structured (indoor outdoor), in contrast to uneven terrain, common obstacles up-curbs down-curbs. Small tires such robots; it is essential identify the curbs determine whether robot proceed. In this paper, minimum heights safe travel over down-curb up-curb derived based geometric analysis. Lidar...
Nanoporous-layer-covered TiO2 nanotube arrays (Type II TNTs) were fabricated by two-step electrochemical anodization. For comparison, conventional I also prepared one-step Types and TNTs detached selective etching then transferred successfully to a transparent F-doped SnO2 (FTO) substrate sol-gel process. Both FTO/Types allowed front side illumination exhibit incident photon-to-current efficiencies (IPCEs) in the long wavelength region of 300 750 nm without absorption light iodine-containing...
CdSe quantum dots (QDs)-assembled, free-standing TiO2 nanotube arrays (TNTs) are transferred to transparent fluorine-doped tin oxides (FTOs) using a sol-gel process. The TNTs on the FTO (FTO/TNT) not only provide an efficient 1-dimensional electron pathway with few recombination centers, but also allow front side illumination through FTO, providing significantly enhanced lifetime and light harvesting compared conventional Ti foil nanoparticles-based mesoporous films FTO. These effects help...
