A toilet-seat based cardiovascular monitoring system created by a team of Rochester Institute of Technology researchers aims to lower the hospital readmission rates of patients with congestive heart failure.
In the blockbuster 'Terminator' movie franchise, an evil robot morphs into different human forms and objects and oozes through narrow openings, thanks to its 'liquid-metal' composition. Although current robots don't have these capabilities, the technology is getting closer with the development of new liquid metals that can be manipulated in 3D space with magnets. Reported in ACS Applied Materials & Interfaces, the materials could someday find applications in soft robotics.
Little motors power everything from small comforts, such as desk fans, to larger safety systems, like oven exhaust systems - but they could be more precise, according to a research team from Mitsubishi Electric Research Laboratories. An international collaboration from Japan and Massachusetts unveiled an improved algorithm to track motor performance and speed estimation. Experiments demonstrate the potential effectiveness and advantages of the proposed algorithm: fast speed estimation transient and ease of tuning.
A team of researchers working at Berkeley Lab has discovered the strongest topological conductor yet, in the form of thin crystal samples that have a spiral-staircase structure. The team's result is reported in the March 20 edition of the journal Nature.
A detailed examination of the challenges and tradeoffs in the development of a compact fusion facility with high-temperature superconducting magnets.
A study that encompasses 82,000 pre-installed apps in more than 1,700 devices manufactured by 214 brands, reveals the existence of a complex ecosystem of manufacturers, mobile operators, app developers and providers, with a wide network of relationships between them. This includes specialized organizations in user monitoring and tracking and in providing Internet advertising.
A study into the effects of high mechanical pressure on the polyiodide TEAI showed that it brings unusually high electrical conductivity starting from insulating state, suggesting that the material may be useful as a switchable semiconductor. This system could represent an alternative to gel electrolytes and ionic liquids in dye-synthesized solar cells. The paper, 'Pressure-induced Polymerization and Electrical Conductivity of a Polyiodide,' has been published as a Very Important Paper in Angewandte Chemie.
A research team at The Ohio State University has discovered a way to simplify how electronic devices use those electrons -- using a material that can serve dual roles in electronics, where historically multiple materials have been necessary. The team published its findings March 18, 2019 in the journal Nature Materials.
Researchers in China and at UC Davis have measured high conductivity in very thin layers of niobium arsenide, a type of material called a Weyl semimetal. The material has about three times the conductivity of copper at room temperature.
Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences and Stanford University have developed an integrated, on-chip frequency comb that is efficient, stable and highly controllable with microwaves.
