Simulations explain detonation properties in TATB

Two Lawrence Livermore National Laboratory (LLNL) scientists have discovered a new mechanism for ignition of high explosives that explains the unusual detonation properties of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB).

Quantum brakes in molecules

Physicists have measured the flight times of electrons emitted from a specific atom in a molecule upon excitation with laser light. This has enabled them to measure the influence of the molecule itself on the kinetics of ...

Study reveals unique physical, chemical properties of cicada wings

Biological structures sometimes have unique features that engineers would like to copy. For example, many types of insect wings shed water, kill microbes, reflect light in unusual ways and are self-cleaning. While researchers ...

Engineers model mutations causing drug resistance

Whether it is a drug-resistant strain of bacteria, or cancer cells that no longer react to the drugs intended to kill them, diverse mutations make cells resistant to chemicals, and "second generation" approaches are needed. ...

Researchers develop new method for analyzing metal

Warfighters on the battlefield often rely on machines, vehicles and other technologies with rotating parts to complete their mission. Army researchers have devised a new method of testing for a major factor in equipment failure ...

Researchers add order to polymer gels

Gel-like materials have a wide range of applications, especially in chemistry and medicine. However, their usefulness is sometimes limited by their inherent random and disordered nature. Researchers from the University of ...
