Mechanoluminescence goes crystal-free Bending, twisting and contact separation cause pure amorphous solids made from heteroleptic copper(I) complexes to emit light

Team from the Okinawa Institute of Science and Technology (OIST) in Japan show that mechanoluminescence can occur in pure amorphous photoluminescent solids.

If I’m understanding this correctly, X is owned by a white nationalist who pays poor people of color in developing countries to pretend to be working class white Americans to scare other white Americans into being afraid poor people of color from developing countries are going to ruin America?

Las legiones romanas, la infantería púnica, los ejércitos godos, las tropas musulmanas, las huestes cristianas, los ejércitos imperiales, los tercios, los austracistas, los borbónicos, las tropas de Napoleón... no iban por Zaragoza y Madrid para moverse por el litoral mediterráneo.

Template‐Controlled Mechanochemical Dissociation of a Rotaxane The presence or absence of the Pd template used in rotaxane formation selectively leads to two different mechanochemical dissociation pathways. The Pd maintains a smaller cavity size that favors diss....

Look
if you had one ring
with one Pd in it,
and pull everything onto one thread
in one moment.
would you break it
or just let it slip?

This graphic describes the smelly chemicals in skunk spray and how to get rid of the stink. In the first column, the graphic describes the thiol compounds responsible for skunk spray’s smell. The second column explains why the smell persists because of a chemical reaction between some skunk spray compounds and water. The third column outlines chemistry-based methods for eliminating the stinky skunk compounds.

Infographic on the 2025 Nobel Prize in Chemistry, awarded to Susumu Kitagawa, Richard Robson, and Omar M. Yaghi for the development of metal-organic frameworks. The infographic explains that metal-organic frameworks are molecular sponges built up from metal ions and organic compounds that act as linkers. Small molecules such as gases can move into and out of cavities in these frameworks. The graphic highlights some of the MOFs the laureates have developed and concludes by looking at possible future uses of MOFs, including gas storage and extracting water from air.

The 2025 #NobelPrize in Chemistry was awarded today for the development of metal-organic frameworks, molecular sponges with applications in gas storage, water purification and more: www.compoundchem.com/2025/10/08/2...

2025 chemistry Nobel prize goes to the scientists behind metal–organic frameworks Susumu Kitagawa, Richard Robson and Omar Yaghi take top prize for discovery and development of versatile materials with a huge surface area

Susumu Kitagawa, Richard Robson and Omar Yaghi are this year's winners of the Nobel prize in chemistry for their work on MOFs – just a few grams of these materials can have the same surface area as a football pitch. Julia Robinson with the details.

Quantum Josephson junction circuits and the dawn of artificial atoms - Nature Physics In 1985, experiments revealed the quantum behaviour of a macroscopic degree of freedom: the phase difference across a Josephson junction. The authors recount the history of this milestone for the development of superconducting quantum circuits.

Medicine Nobel goes to scientists who revealed secrets of immune system ‘regulation’ Mary Brunkow, Fred Ramsdell and Shimon Sakaguchi discovered cells that protect the body from autoimmune diseases.

This year’s Nobel Prize in Physiology or Medicine has been awarded to three scientists for discovering a class of immune cells that help to prevent the body from attacking its own tissues

This is an excellent illustration of how useless the "Impact Factor" metric is.

The most influential multidisciplinary chem journals are JACS and Angewandte. They did not make the list.

In this short ad hoc 🧵 I will analyze in real time what made the list and why. I have a bad feeling about this.
