香港理工大學高等研究院於2023年4月21日成功舉辦以「綠色化工與分子篩催化」為題的公開講座(混合模式)。講座由中國工程院院士、中國石化上海石油化工研究院院長楊為民教授主講,吸引了來自亞洲、歐洲、北美10多個國家和地區的120多名現場及網上參加者。講座亦在嗶哩嗶哩、微博等多個社交媒體平台進行直播,在線觀看人數超過11,000人次。
講座由理大協理副校長(研究與創新)王鑽開教授以歡迎辭及講者介紹揭開序幕。楊教授介紹了其團隊在綠色化工領域的研究進展,包括基於分子篩催化材料的綠色化工技術開發與實踐,以及新型分子篩催化材料的應用,並分享了他對行業未來趨勢的展望。 隨後的問答環節由應用物理系客座教授曾適之教授主持,一眾參加者與楊教授進行了富有成果的交流。

In this lecture I consider the fundamental, challenging and largely unsolved problem of deriving rigorously the most popular kinetic equations, starting from the laws governing the dynamics of microscopic systems. I plan to present classical and recent results, discussing also some present perspectives.

We investigate reversal and recirculation for the stationary Prandtl equations. Reversal describes the solution after the Goldstein singularity, and is characterized by regions in which u > O and u < 0. The classical point of view of regarding the Prandtl equations as an evolution equation in x completely breaks down since u changes sign. Instead, we view the problem as a quasilinear, mixed-type, free-boundary problem. This is a joint work with Sameer Iyer.

Models arising in biology are often written in terms of Ordinary Differential Equations. The celebrated paper of Kermack-McKendrick (19271, founding mathematical epidemiology, showed the necessity to include parameters in order to describe the state of the individuals, as time elapsed after infection. During the 70s, many mathematical studies were developed when equations are structured by age, size, more generally a physiological trait. The renewal, growth-fragmentation are the more standard equations. The talk will present structured equations, show that a universal generalized relative entropy structure is available in the linear case, which imposes relaxation to a steady state under non-degeneracy conditions. In the nonlinear cases, it might be that periodic solutions occur, which can be interpreted in biological terms, e.g., as network activity in the neuroscience. When the equations are conservation laws, a variant of the Monge-Kantorovich distance (called Fortet-Mourier distance) also gives a general non-expansion property of solutions.

Universities conduct research for three reasons: to educate students, to contribute to society, and to understand the world. While society often holds a view of the scholar as a solitary and singular genius, in reality scholars today participate in a highly collaborative, worldwide search for shared understandings that stand the test of time and the scrutiny of others. The problems in the 21st century often demand effort by teams of researchers with resources at scale: laboratories and equipment, compute resources, and expert staffing. Working with faculty, students, and other stakeholders to identify the greatest opportunities and the resources needed to address them is both a privilege and a challenge for modern academic administrators. In this talk, I will share three examples: fostering collaborative proposal-writing; planning for shared capabilities in experimental facilities, data, and computation; and transforming academic structures.

中國戲曲源自新石器時代的巫術儀式,經歷漢代百戲、唐代戲弄和北宋雜劇,在北宋末融匯了多種形式的演出藝術、民歌、文人曲子及多種演唱文類,發展成戲曲鼻祖「南戲」。粵劇是清代地方劇種百花齊放的產品,既保留着近乎巫術儀式的《祭白虎》,也承傳着崑曲牌子、秦腔梆子、徽劇二黃、宋明南戲和元雜劇的劇目,堪稱中國戲曲的縮影。本講座概述當代香港粵劇的傳承狀況和中國戲曲的歷史面貌,從中探討粵劇如何保留和發展傳統戲曲的元素。講座將論及粵劇神功戲的演出、《祭白虎》儀式、戲班結構、行當、劇目題材、唱腔特點和傳承。

作為宋遼夏金時期的一個王朝,西夏歷史文化有突出的特色,同時與中原文化有著內在的、緊密的聯繫。西夏參照漢字創制了民族文字西夏文,形成了很多文獻;吸納儒學,尊孔子為文宣帝;提倡漢學,實行科舉,培養人才;借鑒中原王朝法律,編纂法典,保存了最早的少數民族文字《律令》,豐富中華法系;接受中原社會習俗,存留下大批珍貴社會文書;弘揚中原印刷術,發明木活字印刷,有最早的活字印刷實物;尊崇佛教,翻譯中原大藏經,出土了數千卷佛經。西夏同時也吸收了臨近吐蕃、回鶻等民族的文化。西夏文化是中華民族優秀傳統文化的有機組成部分,對中華民族文化做出了重要貢獻。

本演講的出發點是《西廂記》在法國的傳播與接受,從儒蓮、巴贊的戲曲翻譯談起,說明《西廂記》故事如何被十九世紀的歐陸漢學家理解,進而創發出風貌各異的紅娘、鶯鶯與張生等角色類型。本演講也將觸及晚清民初在法國的外交官、留學生,說明他們如何譯介或改編《西廂記》,並與法國文學界激盪出不同模式的文化交流。由此延伸出的議題是熊式一、夏志清等身處英美國家的華人學者,淺析他們如何將《西廂記》置放於知識傳播的脈絡下,讓《西廂記》在二十世紀成為西方讀者認識中國戲曲的重要媒介之一。
