Abstract

Three well-known spatial interpolation approaches, namely, kriging, inverse distance weighted, and slpine, were evaluated and used to identify hot-spots of soil available P in a hilly area. This study aims to evaluate different well-known spatial interpolation approaches for soil available P in a hilly area. Average Standard Error, Root Mean Square Error, Root Mean Square Standardized Error, and Mean Error were used to evaluate the performance of different methods. The krigingplus second trend effect model performed better than the inverse distance weighted and spline techniques in predicting soil available P spatial variability. The analyses of statistical and kriged map indicated that a general deficiency of soil available P in the study area.

Abstract

This paper introduced the research progress made in foreign countries on selective and non-selective asparagus harvesting, planting, and ridging machines; and asparagus target recognition research, combined with the actual situations and asparagus planting situation of our country. The paper also put forward some suggestions. According to different regions situation in China, to research and develop small size green asparagus harvesting machine; introduce and develop middle size, non-selective white asparagus harvesting machine can not only reduce the labor intensity of bamboo farmers, but also improve operation efficiency, and increase the local farmers' income. This paper aimed at providing references for developing the mechanization of asparagus industry in China. [ABSTRACT FROM AUTHOR]

13. NIR-II photothermal conversion and imaging based on a cocrystal containing twisted components.

Abstract

On account of the scarcity of molecules with a satisfactory second near-infrared (NIR-II) response, the design of high-performance organic NIR photothermal materials has been limited. Herein, we investigate a cocrystal incorporating tetrathiafulvalene (TTF) and tetrachloroperylene dianhydride (TCPDA) components. A stable radical was generated through charge transfer from TTF to TCPDA, which exhibits strong and wide-ranging NIR-II absorption. The metal-free TTF-TCPDA cocrystal in this research shows high photothermal conversion capability under 1064 nm laser irradiation and clear photothermal imaging. The remarkable conversion ability-which is a result of twisted components in the cocrystal-has been demonstrated by analyses of single crystal X-ray diffraction, photoluminescence and femtosecond transient absorption spectroscopy as well as theoretical calculations. We have discovered that space charge separation and the ordered lattice in the TTF-TCPDA cocrystal suppress the radiative decay, while simultaneously strong intermolecular charge transfer enhances the non-radiative decay. The twisted TCPDA component induces rapid charge recombination, while the distorted configuration in TTF-TCPDA favors an internal non-radiative pathway. This research has provided a comprehensive understanding of the photothermal conversion mechanism and opened a new way for the design of advanced organic NIR-II photothermal materials., Competing Interests: There are no conflicts to declare., (This journal is © The Royal Society of Chemistry.)
