New cleaning technique boosts electronic and photonic prospects of aluminum nitride
A group of researchers led by Cornell is unlocking the full potential of aluminum nitride—an important material for the advancement of electronics and photonics—thanks to the development of a surface cleaning technique that enables high-quality p.....»»
Will silicon nitride and common chemistry help revolutionize genomic sequencing?
Genomic sequencing has revolutionized our understanding of medicine and evolution, such as identifying hereditary anomalies. Arrays of nanometer-sized holes—nanopores—in silicon nitride can in principle dramatically speed up and lower the cost of.....»»
Delayed slow ocean response to carbon dioxide removal causes asymmetric tropical rainfall change
Using fossil fuels causes large amounts of carbon dioxide (CO2) to be emitted, which is one of the major greenhouse gases responsible for global warming. The climate changes under increasing CO2 radiative forcing (called "CO2 ramp-up") have been wide.....»»
Radical action is needed for the climate. This means transforming the way we do science
Record-breaking heat waves, droughts and floods make regular headlines around the globe, and scientists say the risk, frequency and intensity of these weather extremes are tied to the ever-increasing levels of planet-heating gases we pump into the at.....»»
Differentiating right- and left-handed particles using the force exerted by light
Researchers investigated the polarization-dependence of the force exerted by circularly polarized light (CPL) by performing optical trapping of chiral nanoparticles. They found that left- and right-handed CPL exerted different strengths of the optica.....»»
Vultures Prevent Tens of Millions of Metric Tons of Carbon Emissions Each Year
Vultures get a bad reputation for their carrion-scavenging ways, but their dietary habits prevent the release of greenhouse gases.....»»
Apple Headset patent application describes letting you see invisible and hidden things
An Apple Headset patent application describes how the device could enable users to see things that are invisible, or hidden from view. This could range from invisible gases, through physical objects hidden from view, to things like Wi-Fi. This could.....»»
