Abstract:
β-blockers are a type of emerging chemical in the last century which is widely used for various purposes. And β-blockers are mostly used in the medical field to cure several diseases and they also could be used in the early stage of cancer. However,β-blockers could also be applied as a stimulant in sports, which leads to unfairness in sports. Therefore, it is imperative to investigate the plausible alternatives in order to determine β-blockers efficiently with high sensitivity and better Limit of Detection (LOD). Electrochemical techniques are the ones with the highest efficiency, sensitivity, conductivity, and accuracy. Among those electrodes, the electrodes based on carbon material stand out owing to their high conductivity, inexpensive price, high sensitivity, and flexibility. In this regard, it mainly analyses some electro analytical techniques for determining β-blockers based on carbon-based electrodes evidenced by previous research. The flexibility of each method and the advantages of modification were also emphasized. In addition, the potential and prospect of the future are summarized.

Abstract:
The ocean, covering 70% of the earth’s surface, is regarded as one of the largest reservoirs of renewable energy. Especially, the waves, with violent fluctuations, are widely distributed on the ocean, producing enormous energy yet to be fully exploited. Wave energy is known as clean, renewable energy in the global energy field with broad prospects. Its wide distribution, enormous content and high quality enable the wave energy to possess tremendous potential value in the global energy market. However, the wave energy faces the inevitable issues of relatively low efficiency and instability, and it still requires further scientific researches and more practical tests before fully exploiting the potential value. In this report, the development and current situation of wave energy are mainly discussed, including the history, implementations, environmental impacts, economics. Our group aims to gather comprehensive information about the wave energy, analyze the multiple impacts of the implementations and find out the promising field in the future development of wave energy.

Abstract:
The iron oxide nanoparticles used in the combined imaging technology of PET and MRI have excessive iron in the local area of the patient, causing cytotoxicity and other problems. Therefore, in this work, three different coating-coated nano-iron oxide particles (Fe3O4 NPs) are introduced. First, different lengths of heparin oligosaccharide (HO) are coupled to the nanoparticles’ surface, improving the imaging contrast by controlling the length of HO. The second method is to coat the surface of nanoparticles with N, N, N-trimethyl chitosan (TMC) coating to couple breast cancer receptors to TMC, so as to realize targeted detection of breast cancer. The third method aims at improving the stability and biocompatibility of imaging agents in the human body and reduce the cytotoxicity of the imaging agent in the liver, such as coating the surface of nanoparticles with hydroxyapatite coating.

Abstract:
The Three Gorges Project is the biggest water project, and it has important strategic value as well as deep environmental effects. So, it’s necessary to implement environmental supervision in this area. However, there is environmental supervision dilemma which is discussed in this article: the legislative conflict, disordered environmental monitoring system and fragmentation of geographical position. In this study, in order to improve the environmental supervision implementation in the reservoir area, the cause and status quo in terms of those problems mentioned above are analyzed. Countermeasures such as resolving the legislative conflicts, building a unified and coordinated environmental monitoring system, and handling the cross-regional water environment supervision are provided.

Abstract:
This paper gives a general overview of the development of deep geothermal energy, the current technology implementation, the environmental and economic evaluation of geothermal energy system. Typical geothermal systems are introduced respectively including dry steam power plant, flash power plant, binary system, EGS technologies as well as heating system. Some new ideas and models for exploitation are gathered. It’s pointed out that utilizing geothermal fluid step by step (such as applying combined system) can improve the efficiency significantly because of the lower reinjection temperature. For the evaluation of geothermal systems, the emission intensity is nearly zero while it’s noteworthy that the toxic chemical may be released and geological disasters may be caused during drilling and hydraulic fracturing. Geothermal energy is competitive in electricity market due to the low running costs, and the installed capacity of geothermal energy will continue to increase.

Abstract:
This paper illustrates general factors influencing costs and expenses, and prospects of tidal power plants including barrages, lagoons, and streams. After the gathering data from existing papers and analysis, it is concluded that tidal systems are not economically viable mainly due to prohibitive capital costs, so it is believed that governments will contribute the most to the development of tidal energy. Furthermore, having low capacity factors of tidal systems indicates that even those with high installed capacity do not generate electricity as much as other power plants with low installed capacity. In the end, I reached a conclusion that, although with the advantage of predictivity, later researchers need to come out with new designs of tidal system, which can employ its original advantages and at the same time decrease the capital cost significantly

Abstract:
Over the past few decades, the importance of soil environment analysis has become a popular social topic. Because soil environment not only determines the living condition for crops, but also decides their productions. There are many conventional methods that could be used to analyze the properties of soils, but they have some disadvantages. For instance, these methods require expertise to operate it, samples must be destroyed in preparation process, running instruments is costly, and getting spectra is ineffective. Thus, finding an eco-friendly and convenient model to analyze soil properties become a leading direction that is required to be solved. Mid-infrared (MIR) spectroscopy, with broad absorbance range and strong, clear signals, become a common and effective technique in the laboratory. MIR spectroscopy could overcome the limits of the traditional methods, it does not require insipid, tedious, or complex preparation steps, and it provides results with high accuracy. Hence, this article is a general introduction to MIR spectral analysis, and it explained detailly the applications of MIR spectroscopy in soil properties. It not only illustrated the procedures of developing quantitative and classification models based on MIR spectra analysis, but also emphasized on the applications and future sights of MIR spectroscopy in soil environment analysis. MIR spectroscopy can be used to analyze the biological and chemical properties of soils, which is conducive to monitor the living environment for plants. In this way, the state of plants or the production of crops could be optimized. By developing this MIR analytical technique, there would be a significant step being taken in agriculture, botany, zoology, and so on.
