Synthesis and chromatographic evaluating of the core-shell SiO with tunable shell thickness and application for separation of Traditional Chinese Medicine oligosaccharides.

The development of core-shell materials for achieving more efficient and rapid chromatographic separations has remained a key objective in separation science. In this study, monodisperse SiO particles (2-4 µm in diameter) were utilized to fabricate core-shell spheres through a combined approach involving a modified sol-gel process and a biphasic system. The synthesis employed 1,6-bis(triethoxysilyl) hexane (BTMSH), 1,2-bis(triethoxysilyl) ethane (BTEE) as a bridging agent with cetyltrimethylammonium bromide (CTAB) acting as a co-template.

MAFG-AS1 is a novel clinical biomarker for clinical progression and unfavorable prognosis in gastric cancer.

MAFG antisense 1 (MAFG-AS1) is recently identified as a novel lncRNA and serves as a tumor promoter in several types of human tumor. However, no prior study has been performed to evaluate the role of MAFG-AS1 in gastric cancer. In our study, we found MAFG-AS1 expression was increased in gastric cancer tissue samples compared with normal gastric mucosa tissue samples, and associated with poor overall survival in gastric cancer patients at The Cancer Genome Atlas database.

Solvent Engineering for High-Performance PbS Quantum Dots Solar Cells.

PbS colloidal quantum dots (CQDs) solar cells have already demonstrated very impressive advances in recent years due to the development of many different techniques to tailor the interface morphology and compactness in PbS CQDs thin film. Here, n-hexane, n-octane, n-heptane, isooctane and toluene or their hybrids are for the first time introduced as solvent for comparison of the dispersion of PbS CQDs. PbS CQDs solar cells with the configuration of PbS/TiO₂ heterojunction are then fabricated by using different CQDs solution under ambient conditions.
