The structure, morphology, chemical compositions and optical properties of the obtained materials were characterized by the X-ray diffraction (XRD), scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDX) and ultraviolet-visible-near infrared (UV-Vis-NIR) absorption spectra.
Constructing the heterojunction structure between two different semiconductors was proved to be an effective means to improve the photocatalytic activity.

The present book covers all aspects of the field, including Photophysics, Luminescence and Spectroscopy, Magnetic Materials, Nuclear Medicine Applications,Minerals and Materials Characterisation, Extraction and Co-ordination Chemistry, Electronic and Electrical Properties, Agricultural Applications, and other NewApplications.

They have been widely used as sweeteners and non-ionic surfactants in pharmaceuticals, cosmetics, and food industries because of their properties of special amphiphilic structure and biodegradable, non-toxic, and odorless[2-3].
The Synthesized monomer was identified as monoester by the MS, therefore, it can be concluded that the monomer acylated position was at the C6 of the glucose ring, the monoester was determined as 6-O-(10-undecylenic acid) glucose ester, and its structure was shown in Figure 8.
The structure of Fig. 8 The rection equatio of sugar-based polymers the product was 6-O-(10-UA) glucose ester, indicating that the immobilized lipase Novozym-435 catalyzed esterification process with good regioselectivity.

The higher temperature step which exceeds 300 °C can be attributed to the decomposition of more thermally stable structure.
Previous studies indicated that differences in surface structures may contribute, to some extent, to the differences in the thermal stable properties of the different films.

From this perspective, barium hexaferrite (BaFe12O19) was chosen as magnetic carrier because of its prominent high performance permanent magnetic nature with hexagonal molecular structure.
The hexagonal structure has high value of permeability (> 1) that leads to high magnetization compared to the spinel-type ferrites [12].

In order to determine the development level of circular economy in the chemistry industry, grade classification needs to be done.
Therefore, we refer to various comprehensive indexes worldwide and design a new evaluation standard to estimate the development degree of circular economy in the chemistry industry, which has five degrees and the grading principle was shown in Table 2.

The macromolecular retention aid(CPAM) is a kind of positive charge material with chain structure and high surface density[2].
The paper bulk gradually declines with the increasing of CPAM dosage in conventional papermaking process, because more and more calcium carbonate keeps in the paper web and densifies the paper structure, what is more, PCC is significantly better for paper bulk than GCC, which may due to that the particle size distribution of PCC is wide and the structure of PCC flocs is loose [3].
