Are polymer capacitors worth the premium over tantalum? GaN grown on silicon: what does the substrate contribute and what does it cost? Iron based superconductors and the fight over pairing symmetry Why do new alloys take a decade to reach the production floor? Materials discovery is moving from the lab bench into simulation — what density functional theory still gets wrong Type I vs type II superconductors: why does one expel field and the other let vortices in? Why is almost everything still built on silicon rather than germanium or gallium arsenide? What does hybrid bonding allow that micro-bump stacking cannot? Metal-organic frameworks pack enormous surface area into a gram — why they still struggle to ship How much of a magnet's cost comes from the dysprosium in it? Why is graphene still mostly a lab material after twenty years of promises? Can superconductivity survive in a film one atom thick? Electronic waste is the fastest growing waste stream and the recycling rate barely moves Why do two labs report different nanoparticle size distributions for the same sample? Silver nanowire vs ITO transparent electrodes: which one survives bending better? What does a metre of high temperature superconducting tape actually cost? Why is heat removal becoming the binding constraint instead of device speed? TEM vs SEM for nanoparticle work: what each one can and cannot tell you Can tunnel FETs deliver sub-60mV/decade switching outside the lab? Backside power delivery: why move the wires under the transistors? Nanoindentation: what a hardness number on a thin film really means Hydrogen rich compounds that superconduct only under enormous pressure Electromigration in copper interconnects: how is it tested and predicted? Why do spacecraft use aluminum-lithium instead of plain aluminum? Bendable vs stretchable electronics: what differs at the material level? Carbon fiber vs aluminum in a car body: where the weight saving stops paying for itself What causes wafer warping and how does it hurt downstream steps? What can replace neodymium magnets in an electric traction motor? Why does blade length grow faster than generator rating? Perovskite tandem cells: what an efficiency record still hides about stability Why does OLED peak brightness fall as the lit area grows? How do you keep silver nanoparticles from clumping inside a coating?
