BACKGROUND Modern high-velocity projectiles produce temporary cavities and can thus cause extensive tissue destruction along the bullet path. It is still unclear whether gelatin blocks, which are used as a well-accepted tissue simulant, allow the effects of projectiles to be adequately investigated and how these effects are influenced by caliber size. METHOD Barium titanate particles were dis...
Annealed bulk crystals of barium titanate (BaTiO3) exhibit persistent photoconductivity (PPC) at room temperature. Samples were annealed in a flowing gas humid argon and hydrogen, with higher flow rate corresponding to larger PPC. When exposed sub-bandgap light, broad infrared (IR) absorption peak appears 5000 cm−1 (2 μm), attributed polaronic or free-carrier from electrons the conduction band....
