Turn-On Conductivity with Proton-Coupled Electron Transport in Metal–Organic Frameworks
Proton-coupled electron transfer (PCET) has been studied for decades in the context of molecular reactivity, but its impact on long-range electron transport is barely understood. When defined broadly ...

Crystallographic Evidence of Size-Dependent Bond Flexibility in Metal–Organic Framework Nanocrystals
Size-dependent electronic, magnetic, and optical behavior suggests that metal–organic frameworks become softer materials as their particle sizes decrease, but direct evidence is lacking. Here, we rep...

The more I reflect on the damage the AI bubble could wreak when it bursts, the angrier I get at the credulousness that has inflated it. Especially in the media, and especially the tech media, which often seems like an industry PR machine. My lastest column.

AI is a bubble that is going to burst
The industry has fostered a cult of personality that seems to leave the tech press starstruck and unquestioning of nonsensical claims

Definitely the most surprised I've been upon acquiring a powder X-ray diffraction pattern, and then looking at the beatiful crystals in an electron microscope! 🔍💎
Using advanced electron crystallography techniques, researchers at Stockholm University have succeeded in determining the structure of the red pigment carmine. It turns out that the substance, used today in products such as candy and paint, has a complex porous structure.
