Prignati do skrajnosti: zgodba o piezoelektričnih materialih in napravah za ekstremne pogoje

 

prof. dr. Andrew J. Bell

Univerza v Leedsu, Velika Britanija

 

 

V predavanju bo predstavljena 20-letna zgodba o tem, kako se je raziskovalna tema, ki jo je gnala radovednost in ki se je ukvarjala s feroelektričnimi materiali, razvila v poslovno združenje vredno dva milijona dolarjev, ki proizvaja industrijske ultrazvočne pretvornike na osnovi modificirane piezoelektrične keramike BiFeO3 za uporabo v ekstremnih pogojih (nad 500 °C). Na tej poti, od dodiplomskega projekta do industrijske proizvodnje, smo odkrili nekaj zanimive znanosti o materialih, se naučili obdelovati materiale na robu nestabilnosti ter premostili akademsko občutljivost, da smo lahko financirali spin-out podjetje in sledili nekaterim nepričakovanim potem do zmernega komercialnega uspeha. V predavanju bom poskušal prikazati sodoben in morda idiosinkratičen pogled na znanost in na posel s piezoelektričnimi materiali.

 

O predavatelju: Andrew J. Bell je profesor za elektronske materiale na University of Leeds, School of Chemical and Process Engineering. Leta 2011 je ustanovil podjetje Ionix Advanced Technologies Ltd. za uporabo novih visokotemperaturnih piezoelektričnih spojin razvitih v njegovi raziskovalni skupini. Objavil je preko 200 člankov in prejel več nagrad s področja znanosti o materialih.

Take it to the limit: a story of piezoelectric materials and devices for extreme conditions

 

Prof. dr. Andrew J. Bell

The University of Leeds, United Kingdom

 

 

This presentation will tell a 20-year long story of how a curiosity-driven, ferroelectric materials research topic developed into a 2 million dollar professional association business, manufacturing industrial ultrasound transducers based on modified BiFeO3 piezoelectric ceramics for use under extreme conditions (above 500 °C). On that journey, from undergraduate project through to industrial manufacturing, we discovered some interesting materials science, we learnt how to process materials on the edge of instability, and we overcame our academic sensitivities in order to finance a spin-out company and followed some unexpected paths to gain moderate commercial success. The talk aims to provide a contemporary and perhaps idiosyncratic view of both the science and business of piezoelectric materials.

 

About the lecturer: Andrew J. Bell is a professor of electronic materials at the University of Leeds, School of Chemical and Process Engineering. In 2011 he founded Ionix Advanced Technologies Ltd. to exploit the new high temperature piezoelectric compounds emerging from his research group. He has published over 200 papers and received several awards from the field of materials science.
