The changes of turgor pressure in guard cells resulted from the massive fluxes of osmotic ions into and out of guard cells through ion channels and transporters are the main driving force for stomatal movement[1].The massive efflux of diverse osmotic anions are mainly mediated by slow and rapid anion channels for stomatal closure,whereas the influx of K^+,the main osmotic cation and

To achieve a better insight into the far-field plasma spatial distribution and evolution characteristics of the 300 W class low-power Hall thruster(LHT)for commercial aerospace applications,a dedicated and integrated plasma diagnostic system composed of seventeen Faraday cups(FC)and two triple Langmuir probes(TLP)is established to investigate the timeaveraged in situ spatial distribution characteristics of far-field ions and *** ion current density(ICD),plasma potential,plasma density,and electron temperature at 1000 mm downstream of 300 W class LHT for commercial aerospace applications in the azimuthal angle range of-90°to 90°were investigated under the conditions of different anode mass flow rates and discharge *** results demonstrated that ICD,beam divergence angle,and mass utilization efficiency increased with increasing anode mass *** double-wings phenomenon was observed in the spatial distribution of ICD at large angles from the thruster axis,which is attributed to charge exchange collisions at increasing vacuum *** plasma electron temperature,electron density,and plasma potential parameters derived from the TLP decreased rapidly in the angle range from 0°to 30°and did not exhibit significant variations above 30°,which was also in good agreement with the results of the measured divergence angle of the *** discrepancy of average ion speed was *** maximum error is better than 31.5%which checks the consistency between the TLP’s results and that of FC to some extent.

Hierarchical Si C nanowire-supported Pd nanoparticles showed high photocatalytic activity for the C–X(X = Br, I) borylation of aryl halides at 30 °C. The Si C/Pd Mott-Schottky contact enhances the rapid transfer of the photogenerated electrons from Si C to the Pd nanoparticles. As a result, the concentrated energetic electrons in the Pd nanoparticles can facilitate the cleavage of C–I or C–Br bonds, which normally requires high-temperature thermal processes. We show that the present Pd/Si C photocatalyst is capable of catalyzing the transformation of a large variety of aryl halides to their corresponding boronate esters under visible light irradiation, with excellent yields.
