However, classic devices have limitations in terms of size and cost and, especially, power consumption—which is directly related to greenhouse emissions. Graphene could change this and transform the future of broadband. Now, Graphene Flagship researchers have devised a wafer-scale fabrication technology that, thanks to predetermined graphene single-crystal templates, allows for integration into silicon wafers, enabling automation and paving the way to large scale production. https://phys.org/news/2021-02-wafer-scale-production-graphene-based-photonic-devices.html Nanomaterials Thu, 11 Feb 2021 10:56:22 EST news532263379 If there's one topic that people can't get enough of, it's cord-cutting. https://phys.org/news/2018-11-gift-ideas-cord-cutters-wannabes.html Consumer & Gadgets Wed, 21 Nov 2018 04:53:16 EST news461998387 Being on time is important – just ask Lewis Carroll's leporine friend – and one group who knows this more than most are particle physicists, whose work revolves around keeping track of near-light speed blips of matter. https://phys.org/news/2018-01-neutrinos-white-rabbit.html General Physics Wed, 17 Jan 2018 09:34:11 EST news435404040 You might not think of an external hard drive as fun, sexy or cool, but the OWC Mercury Elite Pro Dual mini can be any or all of them.

These situations are particularly common in large data centers that make up "the cloud" where institutions farm out their computing needs. So a Cornell computer scientist has come up with a new system, "Datacenter Time Protocol" (DTP), in which signals sent at the speed of light over fiber-optic cables between the computers enable them to stay in sync to within a few nanoseconds. https://phys.org/news/2016-12-syncing-center.html Computer Sciences Fri, 16 Dec 2016 09:48:56 EST news401104125 The amount of data traffic on the internet and between servers in datacenters has exploded in the past few decades and shows no signs of slowing down. For example, Ethernet technology, used in small to medium-sized networks, has evolved from an original speed of 2.94 megabits per second to 100 gigabits per second, an increase of more than 3,000-fold. An IEEE 400 Gb/s Ethernet Task Force has been formed to take the standard up to 400 gigabits per second in the next year or so, and even this may not be enough for some especially data-heavy companies. https://phys.org/news/2016-02-record-breaking-transmission-capacity-paves-faster.html Telecom Thu, 18 Feb 2016 11:13:54 EST news375016421 The Department of Energy's Energy Sciences Network (ESnet) and the National Energy Research Scientific Computing Center (NERSC) have built a 400 gigabit-per-second (Gbps) super-channel, the first-ever 400G production link to be deployed by a national research and education network. https://phys.org/news/2015-11-department-energy-esnet-nersc-blaze.html Telecom Tue, 10 Nov 2015 10:02:44 EST news366372162 TDK Corporation presents the new high-surge series of EPCOS multilayer varistors.

But it really doesn't matter what you call it, says its inventor, Howie Choset—the whole point of the project is to make modular robots that can easily be reconfigured to meet a user's needs. https://phys.org/news/2015-01-six-legged-snake-monster-reconfigurable-modular.html Robotics Wed, 14 Jan 2015 07:50:03 EST news340443553 A robust wireless technology from Siemens is being used to help manufacture massive steel components. In one of the most modern open-die forges in the world, a facility owned by Saarschmiede GmbH, turbine and generator shafts are being manufactured for power plants. During the production process, it is important to ensure precise interaction between the 12,000-metric-ton forging press and the two gantry cranes that hold the workpiece. Siemens accomplished this by installing an industrial-standard WLAN connection between the cranes and the forging press control system. The solution shows that reliable wireless communication can be realized even under extreme conditions of the sort that prevail during the forging of hundreds of tons of hot steel. https://phys.org/news/2014-08-reliable-wlan-red-hot-environment.html Engineering Thu, 14 Aug 2014 08:03:32 EDT news327222204 In the depths of night on August 5th 1914 the British Cable Ship Alert took the first significant action of World War I, severing the five German submarine cables that ran through the English Channel.
