WASHINGTON, D.C., December 20, 2018 — Magnetic recording is the primary technology underpinning today’s large-scale data storage. Now, companies are racing to develop new hard disk devices (HDDs) capable of recording densities greater than 1 terabit per square inch. Perpendicular recording HDDs store data as tiny areas of “up” or “down” magnetization within a thin […]

WASHINGTON, D.C., October 5, 2018 — In the world of catalytic reactions, polymers created through electropolymerization are attracting renewed attention. A group of Chinese researchers recently provided the first detailed characterization of the electrochemical properties of polyaniline and polyaspartic acid (PASP) thin films. In AIP Advances, from AIP Publishing, the team used a wide range […]

WASHINGTON, D.C., September 13, 2018 — Printed electronics use standard printing techniques to manufacture electronic devices on different substrates like glass, plastic films, and paper. Interest in this area is growing because of the potential to create cheaper circuits more efficiently than conventional methods. A new study by researchers at Soonchunhyang University in South Korea, […]

WASHINGTON, D.C., August 21, 2018 — Ceramic materials are used in nuclear, chemical and electrical power generation industries because of their ability to withstand extreme environments. However, at high temperatures, ceramics are susceptible to thermal-shock fractures caused by rapid temperature-changing events, such as cold water droplet contact with hot surfaces. In a novel interdisciplinary approach, […]

WASHINGTON, D.C., August 20, 2018 — Researchers recently discovered that the strength of the magnetic field required to elicit a particular quantum mechanical process, such as photoluminescence and the ability to control spin states with electromagnetic fields, corresponds to the temperature of the material. Based on this finding, scientists can determine a sample’s temperature to […]

WASHINGTON, D.C., July 26, 2018 — As a solution evaporates, the dissolved chemicals concentrate until they begin forming a crystal through a process called nucleation. Industries that use small crystals in pharmaceuticals, food and microelectronics are seeking to understanding this nucleation event. Scientists studying nucleation often use microscopic droplets as miniature experiments that can run […]

WASHINGTON, D.C., November 14, 2017 — High-efficiency electric motors with tailored speed-torques, determined by their magnetic components, are essential for sustainable, successful electric automobile drive concepts. Soft magnetic core engineering plays a key role in these motors, where the main soft magnetic materials used today are electrical steels. But for higher-frequency applications, soft magnetic composites […]

WASHINGTON, D.C., November 14, 2017 — In motors, generators and similar electric machines, the electrical current that powers them generates magnetic fields that magnetize some of the metallic components.  Choosing the right magnetic material is crucial for designing efficient machines, so researchers from the Institute of Electrical Machines (IEM) at RWTH Aachen University in Germany analyzed […]

WASHINGTON, D.C., November 14, 2017 — Is more always better? Researchers from Doshisha University in Kyoto, Japan, sought to find out if that was the case for measuring magnetic field strengths. Their paper, appearing this week in AIP Advances, from AIP Publishing, examines whether a double H-coil method or a single H-coil method is a […]
