摘要：Macroscopic properties of materials stem from fundamental atomic-scale details, yet for insulators, resolving surface structures remains a challenge. We imaged the basal (0001) plane of alpha-aluminum oxide (alpha-Al2O3) using noncontact atomic force microscopy with an atomically defined tip apex. The surface formed a complex (root 31 x root 31)R +/- 9 degrees reconstruction. The lateral positions of the individual oxygen and aluminum surface atoms come directly from experiment; we determined ...

摘要：Focused ultrasound is a platform technology capable of eliciting a wide range of biological responses with high spatial precision deep within the body. Although focused ultrasound is already in clinical use for focal thermal ablation of tissue, there has been a recent growth in development and translation of ultrasound-mediated nonthermal therapies. These approaches exploit the physical forces of ultrasound to produce a range of biological responses dependent on exposure conditions. This revie...
