Abstract

Ryugu is the C-type asteroid from which material was brought to Earth by the Hayabusa2 mission. A number of individual grains and fine-grained samples analysed so far for noble gases have indicated that solar wind and planetary (known as P1) noble gases are present in Ryugu samples with concentrations higher than those observed in CIs, suggesting the former to be more primitive compared to the latter. Here we present results of analyses of three fine-grained samples from Ryugu, in one of which Xe concentration is an order of magnitude higher than determined so far in other samples from Ryugu. Isotopically, this Xe resembles P1, but with a much stronger isotopic fractionation relative to solar wind and significantly lower 36Ar/132Xe ratio than in P1. This previously unknown primordial noble gas component (here termed P7) provides clues to constrain how the solar composition was fractionated to form the planetary components.

X-ray-radiolysis-induced photochemical reaction of a liquid solution enables the direct synthesis and immobilization of nano/micro-scale particles and their aggregates onto a desired area. As is well known, the synthesis, growth and aggregation are dependent on the pH, additives and X-ray irradiation conditions. In this study, it was found that the topography and composition of synthesized particles are also dependent on the types of substrate dipped in an aqueous solution of Cu(COOCH3)(2) in the X-ray-radiolysis-induced photochemical reaction. These results are attributed to the fact that a secondary electron induced by the X-ray irradiation, surface or interface on which the particles are nucleated and grown influences the particle shape and composition. This study will shed light on understanding a novel photochemical reaction route induced under X-ray irradiation. The development of this process using the X-ray-radiolysis-induced photochemical reaction in aqueous liquids enables us to achieve the rapid and easy operation of the synthesis, growth and immobilization of special nano/micro-scale complex materials or multifunctional composites.

To achieve the three dimensional additive manufacturing process, we investigated X-ray radiolysis-induced chemical reaction of Cu(CH3COO)2 solution. Here, we demonstrated synthesis and immobilization of cupric oxide particles onto a silicon or aluminium substrate using X-ray radiolysis directly from a liquid solution. The X-ray radiolysis of Cu(CH3COO)2 solutions was observed to produce curious shaped microstructures consisting of cupric oxide (CuO, Cu2O, Cu4O3) particles and Cu particles. The sizes of the particles depended on the additive type of alcohol. The results indicate that there are several routes and reaction processes for these particles and aggregation to be synthesized. In addition, we demonstrated the synthesis of these particles using X-ray radiolysis cell combined with a solution flow system. The developed technique of X-ray radiolysis enables us to achieve the rapid and easy synthesis of higher-order structures consisting of cupric oxide and copper particles onto the desired area.
