TL;DR: In this article, a preparation method and application of a TiO2-loaded biochar composite material is described, where the composite material takes biochar as a base body, and the surface of the base body is loaded with calcined TiO 2.
Abstract: The invention relates to a preparation method and application of a TiO2-loaded biochar composite material.The composite material takes biochar as a base body, and the surface of the base body is loaded with calcined TiO2.The preparation method specifically comprises the steps that biomass powder is firstly immersed into an aqueous tetra-n-butyl titanate and absolute ethyl alcohol solution, then gel containing biomass is prepared, and finally the gel is pyrolyzed through a tubular atmosphere furnace in a N2 atmosphere to obtain the product.In the preparation process of the TiO2-loaded biochar composite material, pyrolysis of the biomass and calcination of the TiO2 are performed in the same heat treatment process, therefore, the preparation cost is reduced, and the preparation time is shortened.The product has the good degrading effect on dyes in wastewater.

TL;DR: In this paper, the change of urban warming was investigated by several urbanization factors in Changsha, China, and the data of surface temperature (minimum, maximum and mean) of Changsha were analyzed to understand the possible effects of urbanization on the climate of this region.
Abstract: The process of urbanization affects the urban warming. The change of urban warming was investigated by several urbanization factors in Changsha, China. The data of surface temperature (minimum, maximum and mean) of Changsha were analyzed to understand the possible effects of urbanization on the climate of this region owing to the population growth, built-up area expansion and energy consumption increases. The weights of these three factors were calculated by the analytical hierarchy process (AHP). Then, three weights were simulated with nonlinear method to obtain the urbanization development rate which was utilized to reveal the influence of the urbanization factors on the surface temperature. The result shows that there is a significant upward trend in the urban temperatures of Changsha. The temperature increase seems to be closely related to the rate of urbanization between 1993 and 2008, and there is an evidential increase trend of the influence on urban temperature by urbanization during 16 years. It is a quantifiable approach measuring the relationship between urbanization and urban eco-environment, and can be applied for the urban sustainability.

TL;DR: In this article, a house plane design generation method based on the genetic algorithm is presented, which includes first setting number and area range of house rooms according to design requirement; constructing fitness function of the GA according to specific problems required to be optimized in design, then setting output generation mode through the spiral generation logic technology and finally enabling a computer to conduct calculation automatically.
Abstract: The invention discloses a house plane design generation method based on the genetic algorithm. The method includes first setting number and area range of house rooms according to design requirement; constructing fitness function of the genetic algorithm according to specific problems required to be optimized in design, then setting output generation mode through the spiral generation logic technology and finally enabling a computer to conduct calculation automatically. When a designer thinks that the current designed individual meets design requirements, or a generated scheme is generally stable, or time is limited, the evolutionary computation is conducted at any time to obtain a house plane scheme generated by the computer. Compared with a traditional house design method, the method can conduct optimization calculation on specific house design problems and output results through a computer, generates a large amount of design schemes for reference, and can effectively improve house energy-saving design and soil utilization ratio.
