As one of the largest inland megacities in Northwest (NW) China, Xi’an has been facing serious regional haze frequently, especially during winter. The composition aerosols is highly complex due to its unique basinal topography and meteorological conditions. In this study, we characterized morphology, size, individual aerosol particles collected events at an urban site using Transmission Electro...

A new design of luminescent materials by decorating a tetraphenylethene core with four aromatic chromophores is proposed. The generated luminogens exhibit aggregation-enhanced emission and excellent solid-state fluorescence efficiency (93-99%). Efficient non-doped OLEDs based on them afford remarkable efficiencies up to 11 cd A(-1).

Permeability, the ability of rocks to flow hydrocarbons, is directly determined from core. Due to high cost associated with coring, many techniques have been suggested to predict permeability from the easy-to-obtain and frequent properties of reservoirs such as log derived porosity. This study was carried out to put clustering methods (dynamic clustering (DC), ascending hierarchical clustering ...

Introduction: The recognition of groups of terrestrial climate-related landforms has led to the definition of different morphogenetic regions [e.g., 1-2] which have been classified in terms of both mean annual temperature and precipitation. Marchant and Head (2007) [3] used this approach to classify the McMurdo Dry Valleys of Antarctica (ADV) into three separate microclimate zones based on grou...

The Global Stratotype Section and Point for the newly defined Ediacaran System has been ratified at the base of the cap carbonate in Enorama Creek. A near-continuous section from the Marinoan glaciation to the base of the Cambrian is exposed in the Flinders Ranges, with type sections of included stratigraphic units exposed in the area around Brachina and Bunyeroo gorges. The stratigraphy and lo...

Mg Cored wire method is a type of spheroidization treatment method. It has been introduced by many foundries from the viewpoints improving environment safety factory workers, automation and productivity. However, prediction residual content depends on experience because various factors complexly affect each other effects factor yield rate have not clarified theoretically.
