“…The activation energy for the formation of mullite fibers was 741.4 kJ/mol, which was less than most of the data reported in the literature. Zhang and Han [19] produced high purity mullite powders using the solgel method, with tetraethyl orthosilicate and aluminum nitrate as the main raw materials. The authors studied the properties of mullite powder under different pH values and other experimental conditions.…”

“…It has an orthorhombic structure, characterized by the presence of octahedral chains of AlO 6 located at the vertices and in the center of the unit cell, with edges aligned in parallel along the 'c' crystallographic axis. The AlO 6 chains are interconnected by double tetrahedral chains of aluminum-oxygen and/or silicon-oxygen (AlO 4 /SiO 4 ), also aligned in parallel with the c axis [15,[17][18][19]. Mullite has a crystalline structure closely related to that of sillimanite (Al 2 O 3 .SiO 2 ) and both have silicon and aluminum atoms located in tetrahedral sites.…”

Mullite, an intermediate phase of the binary alumina-silica system, is one of the most important phases of ceramic products containing alumina and silica in the initial composition. Its stoichiometry ranges from 3Al 2 O 3 .2SiO 2 (3:2) to 2Al 2 O 3 .SiO 2 (2:1) and its crystalline structure is orthorhombic, characterized by the presence of octahedral chains of AlO 6 interconnected by tetrahedral chains of aluminum-oxygen and/or silicon-oxygen (AlO 4 /SiO 4 ). Properties such as high chemical and thermal stability, low thermal expansion and conductivity, and good mechanical strength enable a wide range of applications. Due to the relevance of this material, it is important for the scientific community to understand its microstructural characteristics, properties, methods of synthesis, and various applications. Therefore, this article aimed to make a comprehensive review on the mullite to gather and present to the reader a series of relevant information that makes it possible to deepen the knowledge about mullite.

“…It is composed of urban points of interest (POIs), the basic units of urban space. And in recent years, web crawler technology has been widely used in various fields [4][5][6], providing important technical support for obtaining the data related to these urban POIs. These open urban POIs data can be used as the important data source for studying the urban internal functions [7,8].…”

Impact of the mixed degree of urban functions on the taxi travel demand

As an important service industry in cities, taxis provide people with an all-weather travel mode. And its demand is greatly affected by the internal functions of the city. It is very important to understand the relationship between the mixed degree of urban internal functions and the residents’ taxi travel demand to alleviate traffic congestion and formulate corresponding urban traffic strategies. This paper combined two heterogeneous data in the main urban area of Xi’an, urban points of interest (POIs) and taxi GPS. Firstly, a spatial information entropy model was constructed to quantitatively evaluate the mixed degree of functions in different spaces within the city. Secondly, the kernel density estimation method was used to analyze the spatial distribution evolution characteristics of residents’ taxi travel demand. A geographically weighted regression (GWR) model was further used to study the spatial and temporal influences of the mixed degree of urban internal functions on taxi travel demand. Results indicate that there is an obvious spatiotemporal pattern in the impact of the mixed degree of urban functions on taxi travel demand. And the GWR model is used to study the impact is superior to the ordinary least squares (OLS). In more developed areas, improving the mixed degree of urban functions will be more attractive than backward areas. It is also found that although the single function of the city has an impact on the taxi travel demand, the result of the single function is not ideal. This study can provide a reference for the optimal combination of basic units of urban space in urban planning, promote the balance of supply and demand of urban taxis, rationalize urban taxis’ operation and allocation, and solve the problems of urban transportation systems.
