1.報告會簡介
報告人:Frederik Tielens教授
時 間:2018年6月5日(星期三)上午10:00
地 點:長安校區 理學院383會議室
主 題:DFT Based Studies on Biological Calcifications
基于密度泛函理論的生物學計算
內容簡介:Solids of biological origin such as hydroxyapatite or calcium oxalates are directly involved in chemistry of “life”. In this broad study around chemistry of life, materials chemistry and computational chemistry we focus here on Calcium Oxalate and Hydroxyapatite. We have performed DFT studies on different interfaces and investigated the interaction with a series of bio-organic molecules, and characterized them by calculating vibration frequencies and chemical shifts, which were compared to experimental data. The final aim is the prediction of the shape of the kidney stone in its natural medium. Another biological mineral that we have studied is hydroxyapatite, being the major mineral component of tooth enamel, dentin and bone in which it is currently associated to biomolecules and various biopolymers. The purpose of this study is to model a surface(s) of hydroxyapatite and analyze the physicochemical properties using the methods of quantum chemistry (periodic DFT) in particular with the software VASP and CP2K.
生物固體,比如羥基磷灰石或草酸鈣,直接參與“生命體”的化學反應。在圍繞生命化學,材料化學和計算化學的廣泛研究中,我們將重點放在草酸鈣和羥基磷灰石上。我們對這些生命固體的不同界面進行了DFT計算研究,并計算了它們與一系列生物有機分子之間的相互作用,并通過計算振動頻率和化學位移對這些相互作用進行了表征。這些結果都很好地與實驗數據進行了比較。我們研究的最終目標是預測腎結石在其天然介質中的形態。我們研究的另一種生物礦物是羥基磷灰石。它是牙釉質,牙本質和骨骼的主要礦物成分。目前發現它在生物體內的形態與生物分子和各種生物高合物有關。這項研究的目的是模擬羥基磷灰石的表面,并使用量子化學(周期性DFT)的方法,特別是VASP和CP2K軟件,分析這些表面的物理化學性質。

報告人簡介
Frederik Tielens (Brussels, 1974)graduated in Chemistry at the Free University of Brussels, Belgium (1996) and earned his PhD degree in Theoretical Chemistry with cum laude at the Free University of Brussels, Belgium (2000), in the group of Prof. P. Geerlings. His doctoral work on the study of adsorption and catalytic properties of zeolites was awarded the Solvay Prize and the second prize of the prestigious international DSM contest. After a post doc in collaboration with ExxonMobil Research he then moved to industry and worked for Altachem and ABSS. In November 2003 he reintegrated university. During that period he obtained a Marie Curie Post Doc grant at the Universitat Jaume I (Spain), and was postdoctoral researcher at the Université Pierre et Marie Curie (UPMC, Paris, France) in collaboration with Yara, where he worked on the reactivity of metal and metal oxide catalysts. In September 2006 he was assigned contractual assistant professor at the UPMC. From 2007 - 2013 he was assistant professor in charge of theoretical chemistry at Surface Reactivity Laboratory (UPMC). In January 2013 he joined the Laboratory of Condensed Matter of Paris (UPMC). Since September 2017 he is appointed professor at the Vrije Universiteit Brussel and leads the group of materials modeling, and became Ma?tre de Conferences "hors classe" of the Sorbonne University. He specializes in three families of materials: Silica, SAMs/noble metals, and biocalcifications.Frederik Tielens has authored over 120 peer reviewed scientific publications.
Frederik Tielens(1974年生于布魯塞爾)畢業于比利時布魯塞爾自由大學化學專業(1996年),并在比利時布魯塞爾自由大學P. Geerlings教授指導下于2000年以優異成績(cum laude)獲得理論化學博士學位。他在沸石的吸附和催化性能方面的博士研究工作獲得了索爾維獎和著名的國際DSM競賽二等獎。獲得博士學位后,他轉入工業界,在埃克森美孚研究部進行博士后研究,其后為Altachem和ABSS工作。2003年11月,他重新回到學術界,在Jaume I大學(西班牙)獲得了瑪麗居里博士后基金資助,其后與Pierre et Marie Curie大學(UPMC,法國巴黎)的Yara合作擔任博士后研究員。在那里他研究了金屬和金屬氧化物催化劑反應性。2006年9月,他被任命為UPMC的合同助理教授。從2007年至2013年,他作為助理教授負責表面反應實驗室(UPMC)的理論化學研究。2013年1月,他加入巴黎凝聚態物質實驗室(UPMC)。自2017年9月起,他被任命為布魯塞爾自由大學(Vrije Universiteit Brussel)教授,并領導材料模擬研究組,同時成為索邦大學(Sorbonne University)的“課外”講師(Ma?tre de Conferences "hors classe")。他專注于三個系列材料的研究:二氧化硅,SAM /貴金屬和生物鈣化。Frederik Tielens已經撰寫了120多篇同行評審的科學出版物。
