Semiconductor photocatalysis can be used to decompose various organic compounds in open air under aqueous conditions with solar energy. A cellulose nanofiber/TiO2 aerogel (CNFT) for rapid photocatalytic degradation of methylene blue (MB) solution was successfully fabricated through a facile hydrothermal method. TiO2 nanoparticles adhered to the surface of cellulose nanofibers as scaffold through a hydrogen bond and were well-distributed. The particle size distribution data showed that the mean diameter of TiO2 nanoparticles was around 6.8 nm. In the system of the as-prepared CNFT, CNF played important roles in adsorption of pollutant and in stopping the electron hole derived from TiO2 from recombining. The composite aerogel exhibited efficient photocatalytic activity in the degradation of pollutant (MB) under ultraviolet light (UV) and sunlight irradiation. The composite aerogel could be regarded as a green and portable photocatalyst, because it was promising for wastewater treatment application as a result of its good high photocatalytic activity and stability under ultraviolet light and sunlight irradiation.

This paper has retrieved 979 literatures in the field of visualization of cultural heritage information between 2000 and 2020 from Web Of Science core collection. With the keys words as the unit of analysis, cluster analysis and co-word analysis as the research methods and SciMAT as the tool, it has identified research highlights and evolution paths in different periods. The research has found that research topics vary a lot in different periods. Part of the thematic studies are strongly related in sequence, the evolutionary relations between topics gradually become complex in the middle and latter period, and 5 evolution paths are presented in general. System is the main research interests and will continue to be the research highlights. Museum becomes a fundamental topic with great potential in the field after continuous integration and regeneration. 3-D visualization, with the largest time span and various research contents, is the fundamental topic in the field.

The original bamboo furniture is green and environmentally friendly and is a good substitute for wood. But at present, the design of original bamboo furniture develops slowly and its added value is not very high. By applying the coordinated evolution principle of subsystems in TRIZ technology evolution theory, this research makes a preliminary exploration on the innovative design methods of original bamboo furniture in form and structure in the purpose of bringing inspiration and new thinking to the innovative design of original bamboo furniture. In this way, promoting the development of original bamboo furniture design faster and better.

This paper, starting from the background of the olfactory experience, analyzes the necessity of the innovative design of the olfactory experience in the bathroom furniture, expounds the concept of the olfactory sensation and olfactory experience, and summarizes the relationship between the olfactory experience and the human's psychological and behavior. This paper also discusses the idea and method of innovative design of sanitary ware based on olfactory experience, and by making an empirical demonstration, it designs two bathroom furniture with fragrance occurrence function, which provides a new idea for the design of olfactory experience in furniture products.
