Toplogredni izpusti, povezani s proizvodnjo in uporabo te energije, znatno prispevajo k podnebnim spremembam. Ali obstaja rešitev za ta problem? V predavanju bomo začeli s fizikalnimi načeli izgube toplote skozi okna, nato pa opisali naš razvoj materialov, ki so prozorni za vidno svetlobo, infrardečo svetlobo pa odbijajo in so obenem odlični toplotni izolatorji. S temi materiali bi lahko nadomestili ali opremili neučinkovita okenska stekla v stanovanjskih in poslovnih zgradbah. Z vrsto zgledov bomo pokazali, kako v proizvodnjo tovrstnih nenavadnih prozornih aerogelov iz odpadkov iz živilske industrije in pivske drozge vključimo bakterije, zaradi česar so taka pametna okna zelo poceni. <o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt;text-align:justify'>Predavanje bo v angleščini.<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><strong><span style='font-family:"Calibri",sans-serif;color:red'>Lepo vabljeni!</span></strong><strong><span style='font-weight:normal'><o:p></o:p></span></strong></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><span style='font-size:12.0pt;font-family:"Times New Roman",serif;mso-fareast-language:SL'><br clear=all style='page-break-before:always'></span><p class=MsoNormal><span style='color:black'>We invite you to the 17th Institute colloquium in the academic year 2017/18.

Greenhouse emissions associated with producing and using this energy contribute substantially to climate change. Is there a solution to this challenging problem? Starting from the physical principles associated with energy loss through windows, we will describe our development of visibly transparent, infrared-reflecting, thermally super-insulating materials that may replace or retrofit the inefficient windowpanes of residential and commercial buildings. Using many demonstrations, we will discuss how production of such unusual transparent aerogels is aided by bacteria, with the source materials in the forms of waste of food industry and beer wort, to make such smart windows highly affordable.<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Cordially invited!<o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p></div></body></html>
