Chemistry scholar wins Asian Core Program Lectureship Award

化學系何卓琳博士獲頒「亞洲核心計劃講學獎」

Dr Ho Cheuk-lam, Research Assistant Professor of the Department of Chemistry received the Asian Core Program Lectureship Award at the 5th New-Phase International Conference of Cutting-Edge Organic Chemistry in Asia held at Kuala Lumpur, Malaysia, from 1 to 5 December. She will deliver a lecture tour for one week in Singapore next year.

The award was presented to Dr Ho in recognition of her outstanding presentation entitled “Polyferroplatinyne Precursor for the Rapid Fabrication of L10-FePt-type Bit-Patterned Media by Nanoimprint Lithography” delivered at the conference. She said, “My research team has developed new materials as patternable precursors and by applying a simple and convenient method, ultrahigh density magnetic arrays can be fabricated in order to meet the data storage demands of modern society.” She was also delighted with the opportunity to interact with chemists from Asian countries to exchange ideas and explore collaboration opportunities during the conference.

As the magnitude of information created and stored grows exponentially, a new type of material with ultrahigh density for data recording is urgently needed. Bit-patterned media (BPM) made with iron/platinum nanoparticles is a promising candidate for the next generation of magnetic recording systems. Owing to the key advantage of the film-forming properties of metallopolymers, patterned metal nanoparticles over large areas can be achieved by nanoimprint lithography (NIL) with high resolution and at very low cost. This newly developed polymeric material combines the merits of both iron/platinum nanoparticles and NIL, offering a single-step fabrication method of BPM at a relatively low cost for data storage devices.

Dr Ho’s research focuses on the synthesis of functional polymers and the fabrication of nanoparticles in highly ordered and densely patterned nanomaterials for potential data storage applications. She also develops materials for organic light-emitting diodes and organic solar cells.

The Asian Core Program aims at enhancing innovative research areas in Asia by organising conferences. The awards are presented to young scientists who show promise in their field.

化學系研究助理教授何卓琳博士於12月1至5日在馬來西亞吉隆坡舉行的「第五屆新階段亞洲尖端有機化學國際會議」上獲頒授「亞洲核心計劃講學獎」,並應邀於明年前往新加坡講學一星期。

何博士在研討會上發表題為「使用納米壓印技術快速製造超高密度磁性存儲陣列的鐵鉑類納米粒子」的論文。她說﹕「我與研究小組研發出一系列新的模板前體材料,再利用簡單方便的納米壓印方法對這些前體材料進行加工,得出超高密度的磁性存儲陣列,以滿足社會對數據存儲的需求。」她表示,在吉隆坡的會議提供一個很好的機會,讓她與來自亞洲國家的化學家進行討論交流,進一步增進合作機會。

隨著資訊量大幅增長,社會需要新型超高密度的材料以應付數據儲存的要求。使用鐵或鉑納米粒子的構型記錄位介質(BPM)無疑是下一代磁性存儲系統中極具前景的一類材料。由於金屬有機聚合物具有易成膜性的顯著優點,使用納米壓印技術(NIL),使材料解析度更高,成本更低廉,便可製備大面積的金屬納米粒子模。這些具備鐵或鉑納米粒子和NIL兩者優點的新型聚合物材料將為製作BPM以應付數據儲存提供一個相對廉價的途徑。

何博士的研究主要集中納米材料的製造,包括合成功能性聚合物及製造高密度有序的納米粒子。這些研究對數據存儲及應用有很大的潛在價值。此外,她研發出一系列用於有機發光二極管和有機太陽能電池等領域的新型功能材料。

亞洲核心計劃旨在透過舉辦研討會,加強亞洲化學家的交流,並頒發講學獎予年輕科學家,表揚他們的傑出研究。
