This paper analyzed the vertical distribution and sedimentation of volatile phenols in bottom waters in Jiaozhou Bay in 1982. Results showed that the pollution level of volatile phenols in bottom waters in Jiaozhou Bay was very low in 1982, which were increasing from spring, and then reaching the peak in summer, and finally decreasing from autumn. Sedimentation was one of the major transfer processes in volatile phenols in Jiaozhou Bay, which was determining the distributions of volatile phenols in waters.
This paper analyzed the seasonal and vertical variations of cyanide in Jiaozhou Bay, and tried to reveal the transfer processes based on investigation data in different seasons in 1982. Results showed that cyanide contents in surface waters were showing obvious seasonal variations, and were in orders of spring < summer < autumn, due to the inputs of cyanide were mainly occurred in wet season. The vertical variations seem to be not regular, and the influences of cyanide contents in surface waters to bottom waters were not significant, because the degradation of cyanide were rapid in summer and early autumn, leading to most of the cyanide was degraded before or in the process of sedimentation.
Constructing precisely oriented assemblies and exploring their orientation-dependent properties remain a challenge for Janus nanoparticles (JNPs) due to their asymmetric characteristics. Herein, we propose a bubble-driven instant quasi-1D interfacial strategy for the oriented assembly of JNP chains in a highly controllable manner. It is found that the rapid formation of templated bubbles can promote the interfacial orientation of JNPs kinetically, while the confined quasi-1D interface in the curved liquid bridge can constrain the disordered rotation of the particles, yielding well-oriented JNP chains in a long range. During the evaporation process, the interfacial orientation of the JNPs can be transferred to the assembled chains. By regulating the amphiphilicity of the JNPs, both heteraxial and coaxial JNP assemblies are obtained, which show different polarization dependences on light scattering, and the related colorimetric logic behaviors are demonstrated. This work demonstrates the great potential of patterned interfacial assembly with a manageable orientation and shows the broad prospect of asymmetric JNP assembly in constructing novel optoelectronic devices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
