Brain-targeting delivery of MMB4 DMS using carrier-free nanomedicine CRT-MMB4@MDZ
Drug Delivery, 2021 Brain-targeting delivery of 1,1′-methylenebis[4-[(hydroxyimino)methyl]-pyridinium] dimethanesulfonate (MMB4 DMS) is limited by its hydrophilic property and chemical instability. In order to solve this problem, herein, we develop a facile protocol through

Si nanocrystals and nanocrystal interfaces studied by positron annihilation [PDF]
Journal of Applied Physics, 2016 Si nanocrystals embedded in a SiO2 matrix were studied with positron annihilation and photoluminescence spectroscopies. Analysis of the S- and W-parameters for the sample annealed at 800 °C reveals a positron trap at the interface between the amorphous nanodots and the surrounding matrix.
