Abstract: Calixarene-based fluorenscent chemosenors, owing to its simplicity, high sensitivity and high detection limits for metal ions in biology and the environment, has been received much attention. Via cliking, calixarene derivations has the group of triazoles, which can bind to metol ions, but also can be modified by various fluorophores. This in-depth review provides an overview of calixarene-based fluorescent chemosensors for metal ions via clicking.

Abstract: A self-developed magnetic detector is presented, which is made up with 64 Hall sensors assembled as an 8×8 serried array in a 50×50mm quadrate circuit wafer, to catch a weak transient magnetic field. The disadvantage accompanying with compact design is the sharp rise of sensor’s working temperature due to the power consumed is on increasing. An approach in which the 64 Hall elements are connected as a three dimensional magnetic-pixel matrix and are driven by dynamic power is presented. The homologous hardware correction illustrative diagram is provided, including its measuring principle and multivariate calibration technique. The experimental results indicated that the proposed method is a beneficial exploration for sensor power supply.

Abstract: nanomaterials have been widely used in sports stadiums, sports turf, athletics track, sports apparel, sports equipment and sports supplements. nanomaterials, however, may have a negative impact on cell lung tissue, liver tissue and brain tissue. Actually, there is a certain biological security risk in it. When the full use of nanomaterials in sports are been taken, the positive effects of development projects and biological research on nanomaterials should be emphasized.

Abstract: With the more demanding requirements of sports training equipment, the applications of high-tech new materials are mainstreams of the new century sporting goods industry. In this paper, there is introduction of the application of new fibers in the field of sports training equipment and their applied advantages, and it plays an important part in improving achievements of sport. Modern sports training development is the essence of science and technology to guide the modern development of new material.The advantage of high-tech new materials, examples and status of application for sports instruments are discussed. As the high-tech new materials have a large number of excellent characteristics, design freedom can be large, which are widely used to improve the player performances with the unique charm in sports training. The high-tech new materials have become one of essential new materials for the development of modern sports training.

Abstract: Carbon fiber materials are not only widely used in aerospace, automotive and other industries, but also develop one of the best sports equipment selection. Elaborated by typical examples, this paper introduces the carbon fiber material used in the game of high-tech equipment and indicates that this material greatly promoted the improvement of sports performance. Carbon fiber materials have become one of the new materials which are essential for the development of modern sports equipment.

Abstract: Composite materials help to improve the needs of all types of sports equipment performance and lightweight. In recent years, composite materials used in the race bike, a variety of bats, climbing wall materials and other aspects have made new progress. In this paper introduces the composites and the characteristic of fiber-reinforced composite materials and indicate several examples about fiber reinforced composites in sports equipment applications.

Abstract: This paper analyzed the type of the material of the racket, as well as the relationship between distribution and the performance of the bottom of the racket, therefore, people can classify it according to the technical style, then matching table tennis racket with different table tennis players ideally, coordinating the performance of the bottom of the racket with the technical style of the table tennis players, so as to maximize the level of the technique and tactics of the athletes as much as possible.

Abstract: Competitive sport is such a sport, which is pursuing higher, faster, stronger and more accurate and which is challenging athletes individual and human’s movement limit. Macromolecule materials with high mechanical properties have the characteristics of higher strength, elasticity and toughness. This paper is planned to study the application of macromolecule materials with high mechanical properties in competitive sports.

Abstract: The application of fiber reinforced composites for sports instruments is introduced. The advantage of fiber reinforced composites, materials selection, products varieties, examples and status of application for sports instruments are discussed.

Abstract: Ammonium polyphosphate (APP) is a well known component of halogen-free flame retardants. Low solubility Ammonium polyphosphate was prepared by polyphosphate acid and urea. The crystal structure of prepared APP was characterized by FTIR and XRD, its thermal stability was tested and compared with those of commercial APP-I and APP-II, and its water solubility was measured and compared with commercial APP-I and APP-II. The conclusion is drawn that synthesized product belongs to the APP-II, and has similar properties as commercial APP-II. Under the optimal conditions, the polymerization degree of APP was 665.4, and the content of NH₃-N and P₂O₅ were 14.36% and 69.84% (wt).
