Surface Chemistry - Thin Film Experiments with Dr Irving Langmuir

This film comes from the 'Nobel Science Series' from the American Institute of Motion Pictures.
Filmed in 1939, it shows Doctor Irving Langmuir, who won the Nobel Prize in Chemistry (1932) for "for his discoveries and investigations in surface chemistry". This film was part of a series presenting Nobel Laureates demonstrating their experiments to inspire enduring contributions to progress. By these living biographies it was hoped their work may be immortalized. The film shows Dr Langmuir, and his associate Doctor Katherine Blodgett, presenting their work as a living record. It starts with a brief clip of a Nobel Prize giving ceremony, before going onto show Dr. Langmuir describing his background and research, including his discovery of the incandescent lightbulb. You then get to see Dr Langmuir in his laboratories at the General Electric Company. He uses the film to describe his interest in science and in particular atoms and molecules. He demonstrates his thin film experiments, showing motion on the surface of liquids before going on to show the spread of protein films on the surface of water and the patterns that can be made. This short film then highlights the work of Dr Katherine Blodgett who for some time acted as Dr Langmuir assistant. It shows her demonstrating her innovation of thin film technologies on glass, creating 'invisible glass' which has a low reflectance. The film shows how some instruments can be made so that they are easier to read/see because the sunlight does not get in the way because they have non-reflecting film.

Prof. Langmuir was a great man. I published one article in the Langmuir journal!

By Jove this is a treasure! I had no idea Langmuir was around when cameras were a thing! And I love how he admits that he and Blodgett were just having fun with them troughs and films at first.

[@lucylangmuir2478]

I never knew he was in my family I’m proud of him

[@billrussell3955]

Really enjoyed watching this after viewing a talk by physicists of today discuss this same concept for the development of superconducting films. Thank you!

[@PolitburoChief]

I came cross finding wikipedia item of Langmuir when I‘m studying dielectric dispersion. Surprisingly, I find another genius. He discovered and invented so many scientific and technical theories and techniques. What a genius！

-中央政治局局长 HES in my family thank you for calling him a genius

[@abhabh6896]

Yeah, I'm here for etching hahaha, so broad and spreading trough multiple disciplines.

[@erikwetterskog3896]

Jesus Christ, this man and his wife were more brilliant in real life than I could ever imagine. A hidden treasure!

Great vid! thanks for uploading. I appreciate it highly

I've used one of his products Invisible glass on my car windshield which takes away troublesome glare. The glare can be blinding especially around dusk or dawn in the NW at certain times of the year...

I remember doing this experiment in the chemistry lab. Cool to know who discovered it. Only we used it to calculate the size of a molecule. It's cool to see you can use it to figure out the shapes too.

[@tvtvvtvt8017]

Curious what lab was this for and when? My Ph.D. was in Unimolecular Electronics and we used Langmuir Blodgett films to create organic monolayers

[@HCBCHEMISTRY]

@@tvtvvtvt8017 it was in the chemistry lab to measure the length of a molecule.

here I am watching how an old man played with water 100 years ago and I feel enlightenment.

[@ekaterinapivovarova880]

Katharine Blodgett worked with Langmuir ay list 10 years...
