奈米碳材合成與應用
近年來奈米碳材(carbon nanomaterials)的研究不只影響了物理、化學、材料科學以及工程學的研究方向，其優異的物理及化學特性(包括高導電特性，高導熱特性，高機械強度，高比表面積等)更提供工業界開發前瞻應用的可能性。奈米碳材主要是奈米結構化的碳材料，包括奈米碳管(carbon nanotube)、石墨烯(graphene)以及相關衍生結構等，其微觀結構會影響材料所表現的巨觀物理及化學特性。我們的主要研究興趣為開發奈米碳材合成以及結構控制技術，透過化學合成以及物理控制的方法調控奈米碳材的結構，進而控制奈米碳材的物理以及化學特性。相關產業應用可包括能源，光電，生醫，以及複合材料等。代表論文請參考(Chiang, W.

大氣常壓微電漿技術
大氣常壓微電漿(microplasma)是一種可在大氣常壓下穩定產生的微型化電漿，其電漿體直徑可控制在微米(µm)等級，因此具有高能量密度的特性。搭配微反應器(microreactor)設計，前驅物在電漿內之滯留時間可調控在微秒(µs)至奈秒(ns)之間，可應用於金屬，合金以及無機奈米粒子(nanopartilce)的合成(<5 nm)。我們的研究興趣為開發大氣常壓微電漿技術，藉由微電漿化學的控制來調控奈米粒子的粒徑分布以及組成，並透過微反應器的設計，開發可連續合成高純度奈米粒子的乾淨製程。應用領域包括能源，光電，生醫以及催化反應等。代表論文請參考(Chiang, W.
