Message from our President
Welcome our members, fellow Rotarians, friends, and guests. Thanks for joining our weekly meeting!
WEEKLY FUNNY WITH SHAGS
We believe laughter is an important part of life, and we should all make time to laugh a little. This segment of our meeting is meant to tickle you just enough. These funnies are curated by member Steven "Shags" Shagrin!
Know the Pros and Cons
"This house," said the real estate salesperson, "has both its good points and its bad points. To show you I'm honest, I'm going to tell you about both. The disadvantages are that there is a chemical plant one block south and a slaughterhouse a block north."
"What are the advantages?" inquired the prospective buyer.
"The advantage is that you can always tell which way the wind is blowing."
INSPIRATION
We make a point of celebrating creative approaches to making the world better, and here, we'll highlight an approach being used to create artificial reefs in the Maldives. Cool stuff!
LEARN SOMETHING NEW
LSD Explained
Combine hallucinogens and contraceptives to take a trip without the kids! But seriously...what's it all about? [And who noticed the time length of the video? ;^)]

PROGRAM: Textile Coatings for Personal Cooling
SPEAKER: Trisha Andrew
We bring you a new program every week on innovation, entrepreneurship, and education and how they contribute to service to others.
As the effects of climate change become more severe and widespread, maintaining personal thermal homeostasis becomes both necessary for survival and increasingly energy intensive.
In principle, advanced textiles and garments have the ability to leverage light absorption, transmission and/or reflection, in addition to straightforward convection, to heat or cool bodies in extreme temperature conditions. For cooling, in particular, surfaces adept at selectively reflecting or refracting high-energy incident light (200 nm - 2.5 microns) from the sun while transmitting or emitting infrared light (8-13 microns) from radiant body heat boast the ability to maintain cooler body temperatures, even when exposed to direct sunlight and the open sky.
I will detail the materials science and engineering advances made in my research lab to develop a durable textile coating that transforms common clothing into implements for passive personal cooling. A polyester poplin fabric finished with a microstructured, lamellar coating comprised of calcium carbonate and barium sulfate shows a cooling ability of up to 8°C compared to an unfinished sample, achieving a maximum cooling of 3.4°C below ambient temperature in optically-complex built environments. Wash and durability testing of the lamellar coating revealed no mechanical degradation and no evident attenuation in the material's performance, affirming its resilience and long-term effectiveness as a functional textile coating for personal cooling.
Professor Trisha L. Andrew (she/her/hers) is a Professor of Chemistry, Chemical Engineering and Materials Science & Engineering at the University of Massachusetts Amherst. She directs the Wearable Electronics Lab, a multi-disciplinary research team that uses chemical vapor deposition to create a variety of functional coatings on unconventional substrates, such as textiles, yarns and plants, and demonstrates the uses of these coated samples in energy harvesting/storage and integrated sensing systems.
Trisha began her independent career at the University of Wisconsin-Madison after receiving her Ph.D. from MIT in 2012, and moved her research program to UMass Amherst in 2016. She has unconventional training in the disparate fields of synthetic organic chemistry and microelectronic device fabrication that inform her unique problem-solving skills and varied research interests. Trisha is a David and Lucille Packard Foundation Fellow, a National Academy of Sciences Kavli Fellow, an Air Force Office of Scientific Research Young Investigator, a L’Oréal USA For Women in Science Fellow, a 3M Nontenured Faculty Award winner, and was named as one Forbes’ magazine “30 Under 30” Innovators in Energy.
Members and guests, please welcome Trisha Andrew!

THE ATTENDANCE SURVEY
Thanks for reading and watching this week’s meeting. You have two last things to do before you’re done.
We have a very short attendance survey below for you to fill out to record your attendance.
Visiting Rotarians, this is how you can get an email receipt to pass along to your club’s secretary as proof that you’ve attended our meeting if you need it for makeup.
Non-Rotarian Guests, we would love to see who is dropping by our meetings! This part is optional for you. If you think you may want to join our eClub at some point in the future, we would strongly recommend you fill out the attendance form as it will improve your chances of success for your membership application.
For all members and guests — we strongly recommend and ask that you leave a comment in our comments area below. Tell us how you enjoyed the program. Ask this week’s speaker any questions you might have. Or just stop by and say hello and tell us where you’re from!
Important: Once you submit the Attendance Survey below, please make sure you see the confirmation message. If you get an error message instead, please try the 'submit' button again, and if that doesn't work, please refresh the page and fill out the form again. Thanks!
