It is a good time to reach out to your friends/colleagues who are from the middle east

As a professional military strategist, I just wanted to make sure everyone has a full understanding of the American strategy in Iran, thank you for your attention to this matter

I'm a organic materials chemist with experience in synthesis and characterization of small molecules and polymers. I have recently returned to Ontario after 18 years in the US. I'm looking for opportunities in and around the Greater Toronto Area, if possible. Would love to chat! #chemchat #chemjobs

BREAKING: The Department of Education has ended its directive that attempted to restrict diversity, equity, and inclusion efforts in schools nationwide.

This is a victory for academic freedom and education equity.

C3-Symmetric Photoresponsive Chiral Dopants Based on Tribenzotriquinacene Doping cholesteric liquid crystals (CLCs) with photoresponsive chiral molecules is an effective strategy for devising responsive soft materials, as it allows for the phototuning of the noncovalent interactions in the CLCs, and hence, their helical pitch and optical properties. Here we describe the use of tribenzotriquinacene-based (TBTQ) hydrazone and azobenzene chiral dopants in the modulation of the helical pitch of the LC host, 5CB. The unique C3-symmetry of the TBTQ scaffold enhances the noncovalent interactions with the host and thus the chiral information transfer, resulting in helical twisting power (β) values as high as 147 μm–1. Notably, the TBTQ hydrazone exhibits an unusual deviation from trends observed so far in previous studies, resulting in larger β values for the Z isomer rather than the E one. Moreover, the overall β values for the hydrazone-based dopants are unexpectedly higher than those of the azobenzene dopants. These results indicate that the host/guest interactions are better when the photoswitchable chiral dopant is more rigid, as is the case with the H-bonded Z state of the hydrazone. The large β values and excellent miscibility of the hydrazone-based dopants in 5CB allowed us to design films that reflect visible structural color. The properties of the azobenzene-based dopants precluded their use in such applications. By codoping 5CB with hydrazone and azobenzene derivatives of opposite chirality, we demonstrated reversible handedness inversion upon photoswitching, providing a versatile soft material platform for reconfigurable photonic materials and colorimetric display technologies.

Latest @jacs.acspublications.org a collab with Mastalerz grp @uniheidelberg.bsky.social showing how C3-symmetric TBTQ core affects chiral induction in LCs. Hydrazone > azobenzene with this core. Mixing these two with opposite chirality allows handedness inversion bit.ly/4qAtvYE #openaccess #chemsky

JD Vance visited the Armenian genocide memorial in Yerevan, accurately called it that in a post, then under orders from the Turks and the Heritage Foundation he deleted the post in two hours and replaced without the word “genocide” - the fascist police states always line up.

ICE at the polls! Bannon is basically yelling “fire” in a crowded theater here. His objective is to cause chaos (and suppress votes on the left). And it’s already working.

This threat works on multiple levels and doesn’t have to be “real” to serve its purpose.

Let me explain & offer some advice.

SHOCKING FEDERAL COURT MOMENT: DOJ attorney Julie Le, "The system sucks, this job sucks" to Judge Jerry Blackwell who pressed her on why so many court orders are being ignored by ICE/Trump admin. She asked to be held in contempt just so she could get 24 hours of sleep. @FOX9

This is unreal. An AUSA talking like that in open court is about as close as you can come to a total breakdown. Never heard of anything like it.

Congrats Emilio!

Leading American companies — including Palantir, Deloitte, and private prison giant GEO Group — raked in over $22B from ICE and CBP contracts last year.

Do not forget who is profiting from cruelty and human suffering.

I cannot tell you how much doubt was consistently directed at the Gaza Health Ministry’s casualty numbers and how much pressure was put on news organizations to couch those numbers as unreliable.

Biden himself said they were fabricated!

This is textbook censorship of the highest degree
