Nuclear detonations caught the world's attention this summer when India and Pakistan tested their potential strength. To monitor the Comprehensive Nuclear-Test-Ban-Treaty, scientists at the Department of Energy's Pacific Northwest National Laboratory (Richland, WA) developed two devices for detect nuclear detonations. The Automated Radioxenon Sampler/Analyzer (ARSA) and the Radionuclide Aerosol Sampler/Analyzer (RASA) inspect the atmosphere for traces of radioactive material. Once activated, the systems will be located around the globe as an international monitoring system. ARSA analyzes air samples for radioactive xenon or radioxenon that seeps from underground nuclear explosions. The system collects air samples and processes them to trap the radioactive xenon on cold charcoal. RASA detects fission products from atmospheric explosions. It daily filters a huge volume of air to check for evidence of fission products from a nuclear explosion that attach to dust particles. Information collected by the ARSA, RASA, and other monitoring systems at the global stations will be passed on to an international data center. Call (202) 586-5806.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
