Lawrence Livermore National Laboratory (LLNL) material scientists have found that 3D-printed foam works better than standard cellular materials in terms of durability and long-term mechanical performance. Foams, also known as cellular solids, are an important class of materials with applications ranging from thermal insulation and shock-absorbing support cushions to lightweight structural and floatation components. Such […]
Americans continue to use more renewable energy sources
Anne M Stark, LLNL, [email protected] Americans used more natural gas, solar panels, and wind turbines and less coal to generate electricity in 2012, according to the most recentU.S. energy charts released by Lawrence Livermore National Laboratory. Each year, the Laboratory releases energy flow charts that track the nation’s consumption of energy resources. Natural gas use is up
