Kristalografija v 21. stoletju: doba elektrona?

 

Po mnenju mnogih je kristalografija najpomembnejše znanstveno področje, ki stoji za hitrim znanstvenim in tehnološkim napredkom 20. stoletja. Omogočila nam je pokukati v atomsko strukturo snovi in nam ponudila ogromno informacij o materialih okoli nas, od mineralov do beljakovin. Ključna kristalografska metoda za ta uspeh je bil uklon rentgenskih žarkov. Toda ta metoda ima svoje omejitve, od katerih je ključna ta, da zahteva relativno veliko količino proučevanega materiala. Pred kratkim se je pojavila alternativa uklonu rentgenskih žarkov, ki nima te omejitve: trodimenzionalni uklon elektronskih žarkov. Ta metoda ponuja podobne informacije kot uklon rentgenskih žarkov, vendar pri milijonkrat manjši količini proučevane snovi. V predavanju bom opisal to metodo, njen hiter razvoj v petnajstih letih od njene uvedbe ter vpliv, ki ga je in bo imela na področja znanosti o materialih, kemije in molekularne biologije.

 

Predavanje bo v angleščini.

Crystallography in the 21st century: the age of electron?

 

Crystallography is considered by many to be the single most important scientific field behind the immense scientific and technological progress of the 20th century. It allowed us to peek into the atomic structure of matter and provided us with a wealth of information about the materials around us, from minerals to proteins. The key crystallographic method behind this success has been x-ray diffraction. But this method has its limitations, the key one being that it requires a relatively large volume of the studied material. Recently, an alternative to x-ray diffraction emerged, which does not suffer from this limitation: three-dimensional electron diffraction. This method provides similar information to x-ray diffraction but in materials with more than a million times smaller volumes. In this talk, I will describe the method, its rapid development in the fifteen years since its introduction, and the impact this method has had and will have on the fields of materials science, chemistry, and molecular biology.

 

The lecture will be held in English.
