The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses.
Science is all around us, shaping the way we understand the world and fueling countless innovations that improve our lives.
Water transport in periodic mesoporous organosilicas (PMOs) was studied using pulsed field gradient NMR. A series of isogeometric PMO materials with different chemical compositions of the pore walls ...
It has all the makings of a toxic controversy. Growing evidence suggests that the molecules known as forever chemicals — used in everyday items such as cosmetics, non-stick pans and water-repellent ...
GM plans to roll out a new battery chemistry once scoffed at for its short life, and it'll form a key prong in its continued battery expansion.
Move beyond lithium and its dominance in semiconductors. There exists a group of 17 other metals with mostly difficult-to-pronounce names but whose products are widespread around us. Here’s a full ...
The hydrothermal reactions of both PuO22+ and PuO2 with phosphonates results in the formation of Pu(IV) phosphonates. Pu(CH3PO3)2, Pu[CH2(PO3)2](H2O), and UO2Pu(H2O)2[CH2(PO3)(PO3H)]2 have been ...
Quick geology lesson: There are 17 types of rare earths, and they’re used as the building blocks in cars, semiconductors, missiles, drones, and more. China mines 70% and processes 90% of the ...
The discovery of a metal-rich star packed with both light and heavy elements hints at exotic stellar explosions and the role of ancient dwarf galaxies in seeding the cosmos with uranium and thorium.
