Magnetism fosters unusual electronic order in quantum material

Physicists were surprised by the 2022 discovery that electrons in magnetic iron-germanium crystals could spontaneously and collectively organize their charges into a pattern featuring a standing wave. Magnetism also arises from the collective self-organization of electron spins into ordered patterns, and those patterns rarely coexist with the patterns that produce the standing wave of electrons physicists call a charge density wave.

In a study published this week in Nature Physics, Rice University physicists Ming Yi and Pengcheng Dai, and many of their collaborators from the 2022 study, present an array of experimental evidence that shows their charge density wave discovery was rarer still, a case where the magnetic and electronic orders don’t simply coexist but are directly linked.

“We found magnetism subtly modifies the landscape of electron energy states in the material in a way that both promotes and prepares for the formation of the charge density wave,” said Yi, a co-corresponding author of the study.

The study was co-authored by more than a dozen researchers from Rice; Oak Ridge National Laboratory (ORNL); SLAC National Accelerator Laboratory; Lawrence Berkeley National Laboratory (LBNL); the University of Washington; the University of California, Berkeley; Israel’s Weizmann Institute of Science; and China’s Southern University of Science and Technology.

3D internal structure of rechargeable batteries revealed for the first time

Lancaster University researchers have pioneered a technique to observe the 3D internal structure of rechargeable batteries for the first time.

The research, published in Nature Communications, is led by Professor Oleg Kolosov from Lancaster’s Physics Department in collaboration with University College London and NEXGENNA Faraday Institution Consortium.

The team used a novel 3D Nano-Rheology Microscopy (3DNRM) -based technique to visualize the 3D nanostructure inside rechargeable batteries, from the molecular scale electrical double-layer to the nanoscale-thick electrochemical surface layer on the graphite anode surface in a lithium-ion battery.

For the first time, this enabled the direct observation of the progression of the whole three dimensional structure of the solid electric interface (SEI), a nanoscale passivation layer formed on the battery electrode-electrolyte interface, that predetermines key battery properties.

If you hold one wire mesh on top of another one and look through it, you'll see a larger pattern called a moiré pattern formed by the overlapping grids of the two meshes, which depends on their relative twisted angle. Scientists developing new materials are actively studying moiré patterns in overlapping atomically thin materials — they produce intriguing electronic phenomena that includes unconventional superconductivity and ferromagnetism. Supercomputer simulations have helped scientists reve

don’t go down the rabbit hole of plastic cups, bottles, utensils, plates, etc. if you don’t want to feel like we are directly being killed on purpose. “bpa free” is almost double talk, because there are so many other carcinogenic chemicals in essentially all plastics.

even hot-liquid paper cups, unless you get organic ones that use corn starch to insulate them, have that same shit smeared all inside them. it’s damn near inescapable unless you’re always paying attention.

milk or juice in a plastic jug? gotcha. milk or juice in a paper carton that doesn’t use corn starch? gotcha. plastic bottle of delicious, locally sourced spring water? gotcha.

foam cups are one of the worst. completely avoid drinking from those if you can, especially hot liquids. they’re only good for… other crafts.

glass, ceramic, untreated (or organically treated) paper, wood, etc are all much safer. don’t forget to look at what they could be insulated with.
