Abstract Since its first fabrication by exfoliation in 2014, phosphorene has been the focus of rapidly expanding research activities. The number of phosphorene publications has been increasing at a rate exceeding that of other two-dimensional materia

TATB (1,3,5-triamino-2,4,6-trinitrobenzene) plastic-bonded explosives (PBX) were shocked with laser-launched flyer plates. The spectral radiance of the emitted light from a small portion of the microstructure (a “microenvironment”) containing a s

SHOCK COMPRESSION OF CONDENSED MATTER - 2019: Proceedings of the Conference of the American Physical Society Topical Group on Shock Compression of Condensed Matter.
The tabletop shock compression microscope is described, along with some recent applications to problems such as the temperature of shocked TATB (1,3,5 triamino 2,4,6 tri nitrobenzene), hot spots in HMX (cyclotetramethylene-tetranitramine) and detonat

SHOCK COMPRESSION OF CONDENSED MATTER - 2019: Proceedings of the Conference of the American Physical Society Topical Group on Shock Compression of Condensed Matter.
We developed a convenient method to mass produce arrays of 1 mm diameter double-layer plastic-bonded explosive (PBX) charges for tabletop studies of shocked insensitive explosives. In the double layer, a pentaerithritol tetranitrate (PETN) booster ch

In this study, bilayer phosphorene samples were subjected to high pressure using a Diamond Anvil Cell (DAC) and their vibrational properties were studied via in situ Raman spectroscopy. Systematic shifting in the Raman frequency of A1g, B2g, and A2g

TATB (1,3,5-triamino-2,4,6-trinitrobenzene) is a powerful explosive whose dynamical behavior is difficult to study because TATB is so insensitive to initiation by shock waves. We used a tabletop microscope equipped with 0–4.5 km/s laser-launched fl

Electrical transport properties were studied in situ of few layer graphene subjected to plasma-induced sequential fluorination processes. Low-temperature transport properties and Raman spectroscopy were studied ex situ after each fluorination process
