アルゴン雰囲気下のグローブボックスでは、1gのMg(AlH4)2と100 mLのエーテルをフラスコに入れて60min攪拌した後、40℃まで蒸発乾固させて1.8gの白い粉末(即ち一次元錯体重合体)を得た。フィルタ及び基材付きのミリングポットに当該白い粉末を入れ、常温下で、遊星ミリングマシンでボール・材料比が60:1、回転数が500rpmの条件でミリングを1.5時間行い、機械力にて物理的気相蒸着を駆動して基材上で堆積物(即ち錯体重合体のナノロッド)を得た。最後に基材上の堆積物に対し、90℃で熱処理を15分を行って最終的生成物(即ち金属錯体水素化物ナノロッド)を得た。
アルゴン雰囲気下のグローブボックスでは、0.5gのMg(AlH4)2と60 mLのメチルtert-ブチルエーテルをフラスコに入れて40min攪拌した後、45℃まで蒸発乾固させて0.9gの白い粉末を得た。図4に示すミリングポットの中に当該白い粉末を入れた。氷水浴下で横フライス盤の中でボール・材料比が80:1、回転数が450rpmの条件でミリングを1時間行うことで白い粉末サンプルをガス化・堆積させて基材上の堆積物を収集し、さらに堆積物を95℃で10分間熱処理して最終的生成物を得た。
真空グローブボックスでは、2gのMg(AlH4)2と150 mLのエーテルをフラスコに入れて60min攪拌した後、40 ℃まで蒸発乾固させて3.6gの白い粉末を得た。フィルタ及び基材付きのミリングポットの中に当該白い粉末を入れた。氷水浴下で、遊星ミリングマシンでボール・材料比が50:1、回転数が550rpmの条件でミリングを2時間行うことで白い粉末をガス化・堆積させて基材上の堆積物を収集し、さらに堆積物を6h真空化処理して最終的生成物を得た。
アルゴン雰囲気下のグローブボックスでは、1gのLiBH4と100mLのメチルtert−ブチルエーテルをフラスコに入れて60min攪拌した後、−10℃と10Pa未満の気圧下で蒸発乾固させて4.3gの白い粉末を得た。フィルタ及び基材付きのミリングポットの中に当該白い粉末を入れた。ドライアイス浴下で、遊星ミリングマシンでボール・材料比が50:1、回転数が550rpmの条件でミリングを0.5時間行うことで白い粉末をガス化させて基材上で堆積させ、さらに基材上の堆積物を収集して最終的生成物を得た。
真空グローブボックスでは、1gのEu(BH4)2と100mLのテトラヒドロフラン(THF)をフラスコに入れて60min攪拌した後、30 ℃と5Pa未満の気圧下で蒸発乾固させて固体粉末を得た。フィルタ及び基材付きのミリングポットの中に当該固体粉末を入れた。室温下で横フライス盤の上でボール・材料比が70:1、回転数が550rpmの条件でミリングを2時間行うことで基材上で堆積させ、さらに基材上の堆積物を収集し、80℃の条件下で15分間熱処理して最終的生成物を得た。最終的生成物は直径が30ナノメートルのナノロッドであった。
真空グローブボックスでは、1gのYb(BH4)2と100mLのテトラヒドロフラン(THF)をフラスコに入れて60min攪拌した後、30℃と5Pa未満の気圧下で蒸発乾固させて固体粉末を得た。フィルタ及び基材付きのミリングポットの中に当該固体粉末を入れた。氷水浴下で横フライス盤の上でボール・材料比が70:1、回転数が550rpmの条件でミリングを2時間行うことで基材上で堆積させ、さらに基材上の堆積物を収集し、80℃の条件下で15分間熱処理して最終的生成物を得た。最終的生成物は直径が25ナノメートルのナノロッドであった。
