The aim of the study was to prepare indomethacin nanocrystal-loaded, 3D-printed, fast-dissolving oral polymeric film formulations. Nanocrystals were produced by wet pearl milling technique, and 3D printing performed semi-solid extrusion method. Hydroxypropyl methyl cellulose (HPMC) film-forming polymer, glycerol plasticizer. In-depth physicochemical characterization made, including solid-state ...

Charge separation and diffusion in type II multilayered structures of CdTe and CdSe nanocrystals with a polymer spacer are unambiguously proven by surface photovoltage spectroscopy. Holes accumulate in CdTe nanocrystal layers, and the electrons in CdSe nanocrystal layers. An increase of thickness of the polymer spacer strongly decreases the charge separation efficiency. Surface photovoltage tra...

In this study, Gd2O3 nanocrystal (Gd2O3-NC) memories with nanostructure tunneling layers are fabricated to examine their performance. A higher programming speed for Gd2O3-NC memories with nanostructure tunneling layers is obtained when compared with that of memories using a single tunneling layer. A longer data retention (< 15% charge loss after 104 s) is also observed. This is due to the incre...

It has been found that sodium hypochlorite enhanced the chemiluminescence (CL) of the CdTe nanocrystal (NC)-hydrogen peroxide system and that estrogens inhibited these CL signals in alkaline solution. CL spectra were used to investigate the mechanism of the CL enhancement. On the basis of the inhibition, a flow-injection CL method has been established for determination of three natural estrogens.

the synthesis of nb doped batio3 has been investigated under microwave-hydrothermal (mh) conditions in the temperature of 150°c for only 2 h using c16h36o4ti, bah2o2.8h2o and nbcl5 as ba, ti and  nb sources, respectively.  typical experiments performed on mh processing have not yet reported for nb doped batio3.  in the mh process, the formation of high purity nano tetragonal nb-batio3 was stron...

Discrete floating gates, nanocrystals or nitride traps, of Flash memory devices enable aggressive scaling of the tunneling oxide by relieving the total charge loss concern of the continuous floating gate [1]. However, a trade-off between the retention and program/erase (P/E) characteristics still remains. Nanocrystal memories with the direct tunneling oxide can still suffer serious retention de...

Introduction: Magnetic particle imaging (MPI), introduced in 2005, is a new imaging modality that allows the direct visualization of magnetic particle concentration with high sensitivity and unprecedented high temporal resolution (1). The advantages of MPI could be exploited for a variety of purposes, particularly in real-time cardiac imaging. The successful application of MPI relies heavily on...
