Opioids like fentanyl, morphine and oxycodone are the drugs most linked to overdoses in the U.S. Typical screening methods for drug usage involve collection of blood, saliva or urine samples. Now, in ACS’ Analytical Chemistry, researchers demonstrate a pen-like tool that can quickly and non-invasively collect molecules from the skin’s surface to be screened for opioids with mass spectrometry.
A Japanese research team has successfully achieved direct observation of the charge distribution at the interface of ferroelectric domains. This nanometer-scale distribution was measured using a combination of advanced local charge imaging with a state-of-the-art electron microscope and atomic displacement analysis at the picometer (one trillionth of a meter) scale.
These findings represent a significant breakthrough in understanding the behavior of ferroelectric devices—such as multilayer ceramic capacitors (MLCCs)—which are increasingly in demand for miniaturization and enhanced performance.
