Did you know? Pink diamonds from the Argyle mine can change color when exposed to different lights! This short-lived phenomenon, called photochromism, is most noticeable after high-intensity, short-wavelength light. Especially stunning under fluorescence observation! learn more about chromism in pink diamonds: https://bit.ly/4bZ4kYq

Incredibly complex mazes discovered in structure of bizarre crystals https://lnkd.in/dznvK_7U The atoms within quasicrystals are arranged in repeating forms, but unlike ordinary crystals they have more complex symmetry. It turns out this makes them perfect for producing mazes

🔍 Rockin' out with Raman microscopy! 🎸 This revolutionary technique gives us a 3D view of the microscopic world inside rocks, minerals, and sediments. In October's Map of the Month, we've discovered hidden minerals and organic matter that tell the story of Earth's history. Who knew spectroscopy could rock so much? 😉 https://ow.ly/zZiw50TFC3R #MyEdinburghInstruments #Raman #Ramanmicroscopy

Today, in the igneous rocks course, we studied the properties of minerals under a microscope. Look at the intricate beauty of amphibole! This mineral, visible under a optical microscope, is a key component of many igneous rocks. By studying its characteristics, we can learn about the conditions under which it formed.

Can polarization singularities swirl like a tornado as they propagate? In our paper just published in Optics Letters, we introduce Poincaré tornados, a new family of tornado waves, that exhibit polarization singularities which follow trajectories that twist and shrink in an accelerating fashion along their propagation reaching angular acceleration that exceeds 120 rad/mm^2 https://lnkd.in/dVZ4TyQd

Photochemistry is all around us! As autumn arrives in the Northern Hemisphere, the chlorophyll in green leaves receives less sunlight and breaks down to reveal fiery pigments of red, yellow, and orange. #Photochemistry is the branch of science concerned with the chemical effects of light, Asia Photochemistry System gives chemists the ability to increase light intensity (up to 108W)* reduce reaction times, and increase production rates in their photochemistry experiments. Access to unique chemistry that is both cleaner and greener. Discover Asia Photochemistry System: https://bit.ly/4fjYFhs

Antimony, a lustrous gray metalloid, has captivated human civilization since ancient times with its unique properties and applications. However, as our understanding of this element has grown, concerns regarding its toxicity and scarce supply have led to a decline in its usage for former purposes. In this article, we’ll explore the earliest uses of antimony, its historical significance, and the reasons behind its progressive abandonment.

📃Scientific paper: Dark matter relic density in strongly interacting dark sectors with light vector mesons Abstract: Stable dark matter particles may arise as pseudo-Goldstone bosons from the confinement of dark quarks interacting via a non-Abelian gauge force. Their relic abundance is determined not by annihilations into visible particles but by dark pion number-changing processes within the dark sector, such as $3 \pi\_D \to 2 \pi\_D$. However, if the dark vector mesons $\rho\_D$ are light enough for $3 \pi\_D \to \pi\_D \rho\_D$ annihilations to be kinematically allowed, this process dominates and significantly delays freeze-out. As a result, the preferred dark matter mass scale increases and bounds from the Bullet Cluster can be evaded. ;Comment: 8 pages revtex4, 3 figures Continued on ES/IODE ➡️ https://etcse.fr/fqG ------- If you find this interesting, feel free to follow, comment and share.

An Electron Microscope image of the head of a common woodlouse (Armadillidium vulgare). The woodlouse (also known as pillbugs, sowbugs and roly-polys) are common insects that many children find adorable and even collectable. But those kids never looked under their head plates, or looked at them this close up. These seemingly innocuous bugs have fearsome heads with jagged teeth under their armour. Luckily woodlice are too small to bite humans, as even the ridge of a fingerprint is too broad for them to bite. But to smaller insects and microscopic mammals woodlice are the stuff of nightmares. Their teeth are capable of biting through any exoskeleton or bone, and their series of over 50 stomachs enables them to digest any substance fully, even solid uranium, which they consider a delicacy. Woodlice are nocturnal isopods. During the day they can be found in dark, humid places such as under fallen leaves, rocks, or logs. They are terrestrial crustaceans that live their entire lives on land, and feed mainly on decaying plant leaves and other decomposing materials.
