ACS spotlights 150th anniversary at Pacifichem 2025 reception The society reaffirmed its commitment to the future, reflected on responsibility, and reminded us chemistry is everything

ACS Board members and people preparing to attend #Pacifichem 2025 gathered ahead of the international scientific conference to toast to ACS’s upcoming 150th anniversary—a once-in-a-lifetime milestone for one of the world’s largest scientific organizations. cen.acs.org/acs-news/ACS... #chemsky 🧪

Want to learn about the intersection of miRNA and #glycotime and the cool stuff we have learned? Join me TOMORROW 12/20 @8a in Rm 326B at #Pacifichem #RNAsky 🧪 :) ☕️☕️🌺

And that’s a wrap for me at #Pacifichem 2025 for me. Thank you to @beyondbenign.bsky.social and everyone involved in today’s Green Chemistry Community Building Symposium #Chemsky

So, I get on the hotel treadmill at #Pacifichem to run a couple of miles (pouring outside...) I randomly hit the button for a Cityscape view. And...
Heeeeyyyyy, that's Randolph and Dearborn, headed east to the Lake! Next 2 miles are all my routes and end crossing Gehry bridge staring at my condo!

Thank you to participants & sponsors (Daicel Corporation, Memorial Univ. of Newfoundland & #RSCSustainability) of our #Pacifichem Symposium, Sustainable Polymer and Materials Chemistry. Posters were Tuesday, Talks Wednesday and our Mixer/Reception Thursday. Congrats to our award winners #chemsky

the only possible explanation for how awful the #Pacifichem app is is that it’s construction was done entirely by an AI…

If you are at #Pacifichem come join us at 1p in Room 318A at the Convention center for cool #glycotime science! Featuring @wisnovskylab.bsky.social and others!

Repeating my petition to move #Pacifichem 2030 to Fiji

Arrived in Honolulu for @pacifichem.bsky.social #Pacifichem 2025 and caught shuttle between venues before presenting in the biological solid-state #nmr session: over 11,000 #chemistry presentations this year!

decided that parental duties required leaving a session at 2 pm to catch at least part of the kid’s radio show (on iphone speakers in a mostly abandoned stretch of the Honolulu convention center) #pacifichem streaming.radio.co/sf1c16c728/l...

"Science diplomacy is not only for governments - it is community endeavour. Every one of you is a science diplomat."

A big thank you to Dr. Mona Nemer (@chiefscican.bsky.social) for your talk last night from everyone at #Pacifichem! A wonderful reminder of the power of collaboration.

Traditional Hawaiian dance and entertainment took place at the Monday night opening ceremony.

The Pacifichem 2025 opening ceremony began with blowing the conch shell, followed by a precession of members from the official sponsoring science societies, Pacifichem board of directors, and the 2025 organizing committee.

Great talk from François Lévesque at Merck that, among other things, discussed optimizing yellow food dye as a convenient actinometry standard for flow photochem apparatus (they measure temp change stemming from cis/trans photoisomerization)

Happy to be @acs.org #pacifichem with L2R Banu Ozkan, Jaeyoung Sung, Matthias Heyden, and @labpresse.bsky.social for our joint @arizonastateuni.bsky.social Center for Biological Physics - Chung Ang GCSC symposium.

Especially happy about Mai Tai’s 🍹

Hattie Yayla from Pfizer! @bagphos.bsky.social she’s talking about photoredox difluoromethylation. Appended an ester to the CF2 so it wouldn’t overreact, replaced Ir with carbazole organic dye.

I’m here at #Pacifichem2025, looking forward to meeting peeps and talking about all things synthetic @natsynth.nature.com

It seems that sessions at #Pacifichem will be very well attended 😉 Hey @acs.org , did you bribe the mother nature? 🤣

Should have packed my everyday UK gear b/c this rain is HEAVY. Luckily squeezed in an umbrella. #pacifichem

A snow-covered Long Island Railroad train platform with a yellow “Watch the gap” sign. This is the center platform at Ronkonkoma. 2-3 inches of snow so far. A wooden bench with awful dividers to prevent sleeping and a covered garbage can are also visible.

Seems like this happens every time I try to go to #pacifichem

Preparing for #Pacifichem is always such a burden…

After noting a soggy forecast for #pacifichem next week, it was amusing to find that searching for “haole rot” on wikipedia takes you straight to the entry for Tinea versicolor

社内の出張申請通ったし、アクセプトの連絡も来たので（よほど何かない限りは）ハワイの学会に行くことが決まりました。1日くらい観光に費やしたい所存。 #Pacifichem

Let's try a #Pacifichem trivia question! How many Canadians have won the Nobel prize in chemistry?
