I always had a liking for Japan and Japanese language given my keen interest in technology. So, I started learning Japanese not for any other reason but genuine interest. I had learnt German before so learning a new language was not a new concept for me. But I was genuinely surprised when learning the language gave me so much insight into not only the Japanese culture but also the way Japanese people think.
A friend who got his job through the FAST OFFER International Program (formerly Study Go Work JAPAN Program) suggested me to give it a shot. As I already knew about the work culture and way of thinking of Japanese people, I immediately jumped at the opportunity. An opportunity to work in Japan with the added bonus of learning Japanese for free seemed like a great deal. Once I was fluent enough, I applied for the interview rounds. I had to go through various rounds, first being the screening followed by a session with the mentor. All the conversations were in Japanese only, which gave me opportunity to speak confidently. My mentor helped me a lot and thanks to his help, I was selected for an interview with five major companies. And then I set out for Japan.
As this was the first time, I set foot outside my country, I was worried. But the staff at ASIA to JAPAN were extremely helpful and friendly. They did everything from booking the tickets to ensuring we have the documents for visa to being there at the airport to receive us with a warm smile. Even during the interviews, they helped us in understanding what the company’s expectations are and how to tackle the interviews. As I had 5 interviews, my day was very busy, but I did my best and three out of five companies selected me for the final interview. At the end of the interviews, I was selected by Daifuku which was my most preferred company. Next day, I hopped on the bullet train to visit the company factory at Shiga. It was an amazing experience. It was a great chance to learn more about the company and see the products in real time. I’ll be joining Daifuku in April of 2021.
I’m very excited for my new venture into unknown as I will live in Japan by myself. I am very thankful to ASIA to JAPAN for this wonderful opportunity and helping me out to get closer to my dreams.
１．題名：Solid-State Interfacial Dealloying(SSID)法によるナノサイズ多孔金属の作製
２．背景：SSIDはDealloying技術で合金から金属の一つを取り除く技術で、ナノメートルサイズの多孔金属を製造することが可能です。多孔金属の表面積が広いため、電池やキャパシターの強化に応用することができます。SSIDは去年発見されたばかりの新しい技術です。
３．実施内容：
現在SSID技術を基にナノメートルサイズの多孔Ti金属を作製し温度依存性を調べています。私達が使用している素材は合金サンプルTi30Cu70で、スパッタリング方法で、シリコンの上に合金サンプルを鍍金し、合金サンプルの上にMg(マグネシウム)を鍍金します。スパッタリング方法では、Cu、Ti(チタニウム)、そしてMgを入れます。合金の厚さを調節するために、まずCuに電力8Wを5150秒与え続け、同時にTiに電力60Wを5150秒与え続けることにより、合金の厚さが320nmになります。その後Mg鍍金するために、Mgに電力40Wを2152秒与え続け、Mgの厚さが700nmになります。サンプルに熱を加えた時、合金とMgを完全に拡散ができるように、厚さが合金より二倍以上になるようにします。温度を450℃に設定し、SSID技術を使用して合金を拡散させ、MgとCu金属を酸溶液で取り除くことで、ナノメートルサイズの多孔Ti金属になります。
４．結果：
ナノメートルサイズの多孔Ti金属の温度依存性の実験をしており、応用性も調べています。
8月から始めた研究でサンプルができたというレベルで詳細の研究はこれからになります。
