A macroscopic 3D porous graphitic carbon nitride (g-CN) monolith is prepared by the one-step thermal polymerization of urea inside the framework of a commercial melamine sponge and exhibits improved photocatalytic water splitting performance for hydrogen evolution compared to g-CN powder due to 3D porous interconnected network, larger specific surface area, better visible light capture, and superior charge separation efficiency.
A customer commissioned Glasgow, Scotland vehicle graphics company Clyde Wraps to make a 2014 Volkswagen van look like it had been devoured by rust. The vehicle is actually covered in beautifully designed vinyl stickers of corroded car parts. Read the rest
SHE SAID YES!!!

A mild and efficient intermolecular ring-expansion approach was developed for the synthesis of medium-ring lactams by using siloxy alkynes. Key to success is the suitable combination of a superior catalyst and an exceptional nitrogen-protecting group. Control experiments indicated that the reaction is remarkably selective toward the desired lactam formation, even with many possible non-productive pathways.
Growth rings: A mild catalytic synthesis of medium-ring lactams through ring expansion of cyclic hemiaminals was developed. This synthetically useful method also gives insight into the reactivity of both siloxy alkynes and N-acyliminium analogues.
We feel that showing kids you can aspire to any career, regardless of gender, is important. That’s why we’re always excited when we see LEGO sets depicting female minifigs in a variety of careers, especially STEM. Take a look at some items currently available in the LEGO store while perusing some of the new Ideas projects worthy of your votes!
Scientific American has alerted us to a few new LEGO sets you might be interested in.
A few items in their space port tag include these minifigs:
And there’s the McLaren Mercedes Pit Stop:
While these are all AMAZING, Weinstock also notes that with the exception of a branded Doc McStuffins‘ Duplo set, “there are no women of color among the new STEM professionals.”
Ok, now onto the voting portion. You know folks can submit ideas to become real LEGO sets? Well there are some fantastic examples right now. For instance, the “Scientists in History” set created by Mibitat.
“Currently proposed are 8 scientist vignettes, of which 3 or 4 (voted for by you) could be included in the set:
Then we’ve got Lovelace & Babbage:
Ada Lovelace (1815-1852) is widely credited as the first computer scientist and Charles Babbage (1791-1871) is best remembered for originating the concept of a programmable computer. Together they collaborated on Babbage’s early mechanical general-purpose computer, the Analytical Engine. Whilst never fully built in their lifetime, Lovelace’s notes on the engine include what is recognised as the first algorithm intended to be carried out by a machine. Because of this, she is often regarded as the first computer programmer.
And, “Help Ada Junior with her maths homework in the miniature classroom, but just make sure the creepy bat doesn’t steal her beloved teddy bear.”
And finally, a real geologist has created a set showcasing her work! Circe Verba, research geologicst at the National Energy Technology Laboratory writes:
“I’m a female research geologist with a love of legos- this is a sample of my career. The scene here shows research geologists discovering minerals in a limestone rock formation and the characterization of the minerals in the laboratory.
Will you be voting for any of these?

In this Minireview, the major achievements in the acylation of arenes and heteroarenes by CH activation with aroyl groups are summarized and discussed. As the products are carbonyl-containing compounds that are typical products from carbonylation chemistry, the possible inspirations for these reactions are also discussed, as are mechanistic issues and possible problems for carbonylative diaryl ketone synthesis by CH activation.
In splendid acylation: The major achievements in the acylation of arenes and heteroarenes by CH activation with aroyl groups are summarized and discussed, based on the aroyl sources employed. In light of these achievements and their mechanistic studies, possible problems for carbonylative diaryl ketone synthesis by CH activation are also discussed.
I should print this picture out immediately and put it in a fucking frame.
