近日，印尼地方媒體頭版報(bào)道了在中國取得博士學(xué)位的最年輕印尼學(xué)生。他正是從寧波諾丁漢大學(xué)畢業(yè)的博士生Samuel D. Widijatmoko。他的博士研究成果為動(dòng)力鋰電池資源回收提供了一套可行性方案。

最年輕的化學(xué)工程博士

Samuel D. Widijatmoko于去年11月完成他在寧波諾丁漢大學(xué)的博士研究課題并且通過了答辯，拿到了化學(xué)工程博士學(xué)位，刷新了印度尼西亞人在中國取得博士學(xué)位的最小年齡記錄。當(dāng)時(shí)，他的年紀(jì)是24歲10個(gè)月。

Samuel收到了認(rèn)證證書

來到寧諾之前，Samuel一直在印度尼西亞當(dāng)?shù)鼐妥x。但在看到中國巨大經(jīng)濟(jì)、科技潛力之后，他聽從了家人的建議，選擇了寧諾。他希望在中國的這所與眾不同的高校內(nèi)，完成自己的本科學(xué)習(xí)。Samuel說，他很喜歡在寧諾學(xué)習(xí)的時(shí)光，也很喜歡寧波這座友善的城市。

“

這里豐富的國際化資源，眾多優(yōu)秀的伙伴，讓我成為了更好的自己。

完成本科學(xué)習(xí)后，他萌生了繼續(xù)攻讀博士的打算。為了完成自己的博士研究課題，Samuel每天要花七個(gè)小時(shí)做實(shí)驗(yàn)，三個(gè)小時(shí)整理數(shù)據(jù)與查閱文獻(xiàn)。這份自律與刻苦，使得他在導(dǎo)師Philip Hall博士和英國諾丁漢大學(xué)Michael W. George教授的指導(dǎo)下，提前并出色地完成了自己的博士學(xué)業(yè)。2018年，他還獲得了由英國化學(xué)工程師協(xié)會(huì)（IChemE）舉辦的第30屆馬來西亞化學(xué)工程師國際研討會(huì)的“最佳報(bào)告獎(jiǎng)”。

他的導(dǎo)師Philip Hall博士表示，Samuel一直以來都是一個(gè)非常刻苦用功的學(xué)生，很高興可以看到他獲得這個(gè)榮譽(yù)。他的研究對(duì)于全球危險(xiǎn)廢棄物處理和循環(huán)經(jīng)濟(jì)的發(fā)展有著深刻的影響。

有責(zé)任感的工程師

據(jù)Samuel介紹，隨著新能源汽車行業(yè)的快速發(fā)展，2015-2020年中國鋰電池的產(chǎn)量不斷增長。去年，中國鋰離子電池產(chǎn)量達(dá)188.45億只。

隨之帶來的則是廢舊鋰電池的回收處理難題——其含有的的重金屬和有機(jī)溶劑一旦浸入土壤和河流，被農(nóng)作物吸收或在魚類中富集，將對(duì)環(huán)境帶來嚴(yán)重的危害。此外，鋰離子電池中的鈷、鋰和鎳等屬于稀有有價(jià)金屬，任其流失也是對(duì)資源的極大浪費(fèi)。

Samuel的博士研究課題正是從廢舊鋰電池中回收鈷這一稀有元素，用來制造新的鋰電池，實(shí)現(xiàn)材料的閉環(huán)使用。Samuel表示，

“

和石油一樣，稀有元素在地球上的儲(chǔ)量也是有限的，不加以合理的開發(fā)利用，總會(huì)有用完的那一天。

他開發(fā)的動(dòng)力鋰離子電池回收技術(shù)不僅實(shí)現(xiàn)了正極材料所富含的鈷鋰的有效富集，同時(shí)將負(fù)極石墨材料、銅鋁箔片以及隔膜材料分選回收，實(shí)現(xiàn)了集成式的動(dòng)力鋰離子電池的綜合回收，極大程度上提高了現(xiàn)有工藝的綜合回收效率與環(huán)保效益。

目前，該項(xiàng)目已經(jīng)完成了實(shí)驗(yàn)室規(guī)模的研發(fā)。Samuel作為第一發(fā)明人，為該項(xiàng)目申請(qǐng)了發(fā)明專利，有望在將來得以實(shí)現(xiàn)更大規(guī)模的應(yīng)用。他本人也已經(jīng)以博士后的身份加入英國諾丁漢大學(xué)強(qiáng)有力的光電研究團(tuán)隊(duì)，繼續(xù)他的科研生涯。

Samuel表示，他為自己的工程師身份深感自豪。

“

步入21世紀(jì)，人類面臨諸多挑戰(zhàn)——全球變暖、能源短缺、生態(tài)惡化……作為一名工程師，我希望能發(fā)揮所長，努力解決人類面臨的困境，打造人與自然和諧共生的環(huán)境。

當(dāng)前，恰逢寧諾科研展，31個(gè)亮點(diǎn)科研案例在校內(nèi)學(xué)生服務(wù)樓、圖書館、理工樓等幾個(gè)主要建筑內(nèi)集中展出。緊扣聯(lián)合國可持續(xù)發(fā)展目標(biāo)，該展從智能城市、創(chuàng)新材料、保護(hù)生態(tài)多樣性等多個(gè)角度展示學(xué)校在促進(jìn)可持續(xù)發(fā)展方面的科研成就。

UNNC PhD graduate becomes the youngest Indonesian doctoral degree recipient from a Chinese higher education institution

A PhD graduate of the University of Nottingham Ningbo China (UNNC), Samuel D. Widijatmoko has become the Youngest Indonesian to obtain a doctoral degree from a higher education institution in China. Samuel completed his PhD programme and received a PhD in Chemical Engineering in November 2020, at the age of 24 years and ten months.

Before coming to UNNC, Samuel studied in Indonesia. Having noticed China’s significant economic and scientific progress over the past few years, he decided to choose UNNC, a unique university in China, for future study. Here at UNNC, he had enjoyed his time as an undergraduate. After graduation, Samuel was determined to remain in Ningbo to pursue a doctoral degree.

Samuel’s PhD research on “Recovery of Positive Electrode Active Materials from Spent Lithium-ion Batteries” mainly focuses on recovering cobalt from spent lithium-ion batteries (LIB) and reproducing new LIB from old. When speaking of the reason he chose this topic, Samuel remarked that battery recycling research is an important topic, especially concerning the current boom in electric vehicles.

“We are concerned that we will run out of fossil fuel. The rare earth metal is the same and even is potentially less abundant than fossil fuel. We may end up not having enough Ni and Co for future battery demands,” he said.

During Samuel’s PhD study, he spent 7 hours a day doing experiments, followed by 3 hours’ lab report writing. Due to his self-discipline and hard work, he completed his doctoral study in advance, under the supervision of Dr Philip Hall and Prof Michael W. George. He also received the “Best Presentation” award in Environmental Protection from the Institution of Chemical Engineers at the 30th Symposium of Malaysian Chemical Engineers in 2018.

“Samuel was a hard working student and I am really pleased that he has achieved this accolade. His research was very important in dealing with hazardous waste materials which are growing exponentially worldwide. His research showed a path to how all valuable resources in Lithium-Ion batteries can be recovered and reused in the Circular Economy,” said Dr Philip Hall, the leading supervisor for Samuel's research.

Samuel’s team has filed a patent and received external funds for large-scale development and future industrial use. He has also joined University of Nottingham UK as a Postdoctoral Research Fellow to continue his scientific career.

Looking back on his experience in UNNC, Samuel believes that social skills and networking are very important part in university life. He hopes that all UNNC students can make full use of the rich international resources at UNNC, make more friends, and lead a better life.
