Lab researchers achieve '4D printed' material

Sep. 13, 2017 -  
For the first time, Lawrence Livermore National Laboratory ( LLNL ) researchers have successfully 3D printed composite silicone materials that are flexible, stretchable and possess shape memory behavior, a discovery that could be used to create form-fitting cushioning activated by body heat, such...

Using synthetic biology for chlamydia vaccines

Sep. 12, 2017 -  
A multidisciplinary scientific team at Lawrence Livermore National Laboratory ( LLNL ) has made significant advances in developing a vaccine for chlamydia using synthetic biology, sponsored by a two-year National Institutes of Health ( NIH ) grant. They detail their work in a recent paper published...

Lab physicist elected SPIE senior member

Sep. 11, 2017 -  
Lawrence Livermore National Laboratory (LLNL) physicist Regina Soufli has been elected as an SPIE senior member. SPIE, the international society for optics and photonics, bestows the senior member designation on individuals who have distinguished themselves through their professional experience and...

Fast heat flows in warm dense aluminum

Aug. 31, 2017 -  
Thermal conductivity is one of the most crucial physical properties of matter when it comes to understanding heat transport, hydrodynamic evolution and energy balance in systems ranging from astrophysical objects to fusion plasmas. In the warm dense matter (WDM) regime, experimental data are very...

Reducing reflectivity in solar cells and optics with micro- and nanoscale structures

Aug. 30, 2017 -  
When it comes to solar cells, less is more -- the less their surfaces reflect a sun’s rays, the more energy can be generated. A typical fix to the problem of reflectivity is an anti-reflective coating, but that might not always be the best solution, depending on the application. Lawrence Livermore...

Carbon nanotubes worth their salt

Aug. 24, 2017 -  
Lawrence Livermore (LLNL) scientists, in collaboration with researchers at Northeastern University , have developed carbon nanotube pores that can exclude salt from seawater. The team also found that water permeability in carbon nanotubes (CNTs) with diameters smaller than a nanometer (0.8 nm)...

Using real-world data, Lab scientists answer key questions about an atmospheric release

Aug. 23, 2017 -  
In the event of an accidental radiological release from a nuclear power plant reactor or industrial facility, tracing the aerial plume of radiation to its source in a timely manner could be a crucial factor for emergency responders, risk assessors and investigators. Utilizing data collected during...

Lab scientist takes a leap in the dark

Aug. 17, 2017 -  
He could have been a professional trombone player in a jazz ensemble or a chef specializing in New Mexican cuisine. However, Michael Schneider took a very different path. He became an explorer looking for the meaning of the universe in the form of dark energy. With the help of the Large Synoptic...

Shock front probed by protons

Aug. 10, 2017 -  
A shock front is usually considered as a simple discontinuity in density or pressure. Yet in strongly shocked gases, the atoms are ionized into electrons and ions. The large difference in the electron pressure across the shock front can generate a strong electric field. In experimental campaigns...

Exposure to antibacterials from mother to child may cause adverse effects in development

Aug. 9, 2017 -  
Lawrence Livermore National Laboratory (LLNL) scientists have discovered that exposure to environmental levels of triclocarban (TCC), an antibacterial chemical common in personal care products like soaps and lotions as well as in the medical field, can transfer from mother to offspring and...
