Rice University scientists discover a method to turn stubby gold nanorods into gold nanowires of impressive length. The metal wires could be valuable for sensing, diagnostic, imaging and therapeutic applications.

Scientists from NUST MISIS have tested experimental composite materials for aircraft brakes. New materials, reinforced by carbon 'fabric', have turned out to be far more durable than the current analogues. As a result of testing, the scientists developed recommendations to improve the fracture toughness of both existing and developed composite materials for braking systems, which in the long term can improve the reliability and safety of aircraft operation and reduce maintenance costs.

Scientists at Tokyo Tech, Ricoh co. and The National Institute of Advanced Industrial Science and Technology have developed an ultra-low-power atomic clock (ULPAC) for small satellites to enable future communication systems beyond 5G. The proposed device outperforms the current industry standards in various benchmarks, such as size, stability, and power consumption.

Scientists at Tokyo Institute of Technology have developed an advanced phase-locked loop (PLL) frequency synthesizer that can drastically cut power consumption. This digital PLL could be an attractive building block for Bluetooth Low Energy (BLE) and other wireless technologies to support a wide range of Internet of Things (IoT) applications.

Liu's porous carbon fibers can enable high energy density and high electron/ion charging rates, which are typically mutually exclusive in electrochemical energy storage devices.

ORNL story tips: Oak Ridge National Laboratory neutrons investigate novel crystals' ability to capture carbon dioxide from air; gleaning valuable data from Twitter used to quickly map power outages, emergencies; ORNL's lightweight, heat-shielding graphite foam tested at Germany's Wendlestein 7-X stellarator yields positive results in fusion reactors; open source software scales up analysis of motor designs to run on supercomputers.

Researchers at Tokyo Institute of Technology (Tokyo Tech) have designed a 28 GHz transceiver that integrates beamforming with dual-polarized multiple-input and multiple-output (MIMO) technology. Measuring just 3 mm by 4 mm, this tiny transceiver could help improve performances of fifth-generation cellular network (5G) and Internet of Things (IoT) devices.
