Summary: The incorporation of different metal types (Fe, Al, Mn, Zn, and Cu) on MCM-48 synthesized by the direct sol-gel method was investigated. It was found that Fe, Mn, and Zn incorporated into the framework of MCM-48 resulted in increased thickness of the pore wall, leading to better thermal stability. On the other hand, the agglomeration of metal oxides and the nature of aluminum led to a decreased thickness of the pore wall and lower thermal stability in MCM-48.

Summary: A series of quaternary Np(IV) fluorides with the compositions of NaxMNp6F30 were synthesized using a mild hydrothermal synthesis approach, where M = Ti(III), V(III), Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Al(III), and Ga(III), and x = 4 for divalent metals and x = 3 for trivalent metals. The compounds have the same crystalline structure with actinide analogues NaxMAn6F30. The neptunium crystals were used to determine the ionic radii of Np(IV) (1.030(2) Å), Pu(IV) (1.014(1) Å), and Ce(IV) (1.012(2) Å). Radiation damage studies on a surrogate material indicated low resistance to amorphization. Density functional theory calculations were performed to compare the stability of the isotypic cerium and actinide structures by computing the band gaps and enthalpies of formation variations.

Summary: An unexplored tin oxide crystal phase (Sn3O4) was synthesized using a convenient hydrothermal method. By tuning the often-neglected parameters, a new X-ray diffraction pattern was discovered. Through various characterization techniques, this novel material was identified as orthorhombic mixed-valence tin oxide (Sn2SnO4)-Sn-II-O-IV, which is a new polymorph of Sn3O4. It has a smaller band gap (2.0 eV) and higher visible light absorption. This study is expected to improve hydrothermal synthesis and facilitate the discovery of new oxide materials.

Summary: This study investigates nanoparticle transport in hard-to-transfect cells using single-particle motion analysis, cell biology studies, and mathematical modeling. The researchers find significant differences in the transport of nanoparticles in bone marrow-derived mesenchymal stem cells (BMSCs) compared to HeLa cells. They also discover that BMSCs use different biological pathways for cellular uptake, vesicular transport, and exocytosis of nanoparticles compared to HeLa cells. A reaction-diffusion-advection model is used to mathematically integrate the steps of cellular transport and predict nanoparticle delivery in BMSCs. This work provides important insights into nanoparticle transport in hard-to-transfect cells and can guide the design of tailored nanoparticle-based delivery systems.
