New 3D chips could make electronics faster and more energy-efficient
The low-cost, scalable technology can seamlessly integrate high-speed gallium nitride transistors onto a standard silicon chip.
New Pathway for mRNA Drug Delivery Shows Shape of Things to Come
Scientists have discovered the internal shape of tiny drug-delivery particles – called lipid nanoparticles – has a big impact on how well our cells absorb them, paving the way to more efficient vaccine and drug delivery.
Heavy particles, big secrets: What happened right after the Big Bang
Smashing atomic nuclei together at mind-bending speeds recreates the fiery conditions of the early universe and scientists are finally getting a better handle on what happens next. A sweeping new study dives deep into how ultra-heavy particles behave after these high-energy collisions, revealing they don t just vanish after the initial impact but continue interacting like silent messengers from...
Machine learning boosts accuracy of point-of-care disease detection
What if people could detect cancer and other diseases with the same speed and ease of a pregnancy test or blood glucose meter? Researchers at the Carl R. Woese Institute for Genomic Biology are a step closer to realizing this goal by integrating machine learning-based analysis into point-of-care biosensing technologies.
Tunable and parabolic piezoelectricity in hafnia under epitaxal strain
Piezoelectrics are a class of functional materials that have been extensively used for application in modern electro-mechanical and mechatronics technologies. * The sign of longitudinal piezoelectric coefficients is typically positive but recently a few ferroelectrics, such as ferroelectric polymer poly(vinylidene fluoride) and van der Waals ferroelectric CuInP2S6, were experimentally found to...
