概要:
“One-pot regeneration”, which is simple regneneration method of ammonia borane (AB) using hydrazine and liquid ammonia,
…
enables conversion of AB from hexagonal boron nitride (h-BN) after milling hydrogenation. Solution ^<11>B-NMR revealed the presence of AB after NH_3/N_2H_4 treatment of milled h-BN (BNH_x) although the yield of AB was less than 5%. The conversion mechanism was clarified as B-H bonds on the h-BN surface created by ball-milling under hydrogen pressure have an ability to form AB, which was confirmed by Thermogravimetry-Residual Gas Analysis (TG-RGA) and Infrared (IR) analysis. The reaction routes are also the same as regeneration route of polyborazylene because intermediates of AB such as (B(NH_2)_3 and hydrazine borane were found by solution ^<11>B-NMR after soaking BNH_x in liquid NH_3 and hydrazine, respectively. Because of the fact that all reactions proceed on the h-BN surface and no reaction proceeds when neat h-BN is treated, breaking of B_3N_3 ring structure and then creation of B-H bond is the key issue to increase conversion yield of AB.

lands. Of the six Mantodea species, four species, i.e. Statilia nemoralis (Saussure, 1870), Tenodera fasciata (Olivier, 1792), T. angustipennis Saussure, 1869 and Hierodula patellifera (Audinet-Serville, 1839), are newly recorded from some adjacent islands of Miyako-jima Island, and two species, i.e. Mantis religiosa (Linnaeus, 1758) and Amantis nawai (Shiraki, 1908), were collected from previously recorded islands in the Miyako Is. Mantis religiosa and T. fasciata were primarily observed in open grasslands, and in contrast, T. angustipennis was mainly found around forest edges on Tarama-jima I. Few nymphs and an ootheca of S. nemoralis were found in grasslands on Ikema-jima I. and Kurima-jima I. Hierodula patellifera was the most abundant among mantis species during these surveys; a number of adults and a few nymphs of this species were observed in our expedition. For Amantis nawai, specimens of only the adult stage were observed, on the dried leaf litter of the forest floor on Miyako-jima I. In addition, three Mantodea species, M. religiosa, T. angustipennis and H. patellifera, were collected from UV-LED light trap set as a counterplan against Anomala albopilosa (Hope, 1839) (Coleoptera: Scarabaeidae) on Tarama-jima I.
