GE partners with Livermore Labs to explore efficient aircraft fuel injectors (video)
What would you do with six months of dedicated access to 261.3 teraflops of computational power? As you ponder that question, consider the case of GE Global Research, which has just announced its participation with the Lawrence Livermore National Laboratory in an effort to design more powerful and efficient aircraft engines by way of computer simulation. Specifically, GE will partner with researchers from Arizona State University and Cornell University to study the unsteady spray phenomena that's thought to be ideal for fuel injectors. Through Large Eddy Simulation, GE hopes to discover an ideal spray pattern and fuel injector design, and reduce its number of lengthy, real-world optimization trials. While the research is initially aimed at aircraft engines, the knowledge gained from these experiments may work its way into GE's other products, such as locomotive engines and land-based gas turbines.

New periodic table elements finally get names, will probably want to trade them in
Flerovium and livermorium. Prime names for really ugly babies -- or, equivalently, new elements on the periodic table. The International Union of Pure and Applied Chemistry opted for the latter last week, baptizing elements 114 and 116 just about six months after they were first ratified. Back in June, as you may recall, Russia's Joint Institute for Nuclear Research proposed flerovium and muscovium as names for the two ultraheavy elements, while deferring to the IUPAC for final say on the matter. At the time, the organization said it would likely accept any name, as long as "it's not something too weird." Flerovium (Fl), named after Soviet nuclear physicist Georgiy Flerov, apparently passed that litmus test. Muscovium, sadly, did not. Instead, slot 116 will belong to livermorium (Lv), named after California's Lawrence Livermore National Laboratory, which collaborated on the discovery of the element, back in 2000. Bill Goldstein, associate director of Lawrence Livermore National Labs' Physical and Life Sciences Directorate, heralded the decision as a celebration of his institute's collaborative contribution to chemistry: "Proposing these names for the elements honors not only the individual contributions of scientists from these laboratories to the fields of nuclear science, heavy-element research, and super-heavy-element research, but also the phenomenal cooperation and collaboration that has occurred between scientists at these two locations." The nomenclature isn't entirely set in stone, however, as the two names must first endure a five-month public comment period before appearing in chemistry textbooks.
Bridgelux silicon LED could mean bright future for solid state lighting
While Democrats and Republicans squabble over the future of the incandescent light bulb, a Livermore-based company has produced an LED that they claim could lead to brighter, more affordable solid state lighting. By growing gallium nitride on low-cost silicon wafers, as opposed to the typical sapphire and silicon carbide substrates, the company has achieved an output of 135lm/W (lumens per watt) with a color correlated temperature of 4730K-- brighter than any affordable LED lighting solution we've ever seen. Of course, this isn't the first time efficacy of this level has been achieved, and we've yet to see a practical application, but if Bridgelux's numbers are right, this could mean a 75 percent cut in LED production costs. The company expects the technology to make its way to real world lights in the next two to three years -- perhaps by then the furor over pigtail light bulbs will have settled a bit. Enlightening PR after the break.
