Inorganic nanomedicines in the fight against cancer have progressed rapidly during recent years, with the synergistic advantages of multifunctional nanosystems compared to single component. Herein, a drug-combination opinion was introduced into “nanomedicine” based on the understanding of Trojan horse-anti-tumor mechanism of inorganic nano-medicines. Moreover, we reported the green and facile synthesis route of mono-dispersed and rod-like zein-conjugated ZnO/Cd(OH)Cl hierarchical nanocomposites. We found that the nanocomposites exhibited high-efficiency killing ability to tumor cells through lipid peroxidation mediated-membrane disintegration route. The safety studies in BALB/c mice didn’t detect injection anaphylaxis, hemolysis and cytotoxicity. More interestingly, the nano-composites could specially accumulate in liver and kidney, which will be helpful for targeting cure to these regional cancers.
BiOCl nanosheets were annealed at different temperatures. The effect of annealing on structures and properties was characterized by X-ray diffraction (XRD), N2 adsorption-desorption, UV-visible diffuse reflectance spectroscopy (DRS) and photoluminescence spectroscopy (PL). The photocatalytic performance was evaluated by photodegrading Rhodamine B (RhB) under UV light irradiation. It was found oxygen vacancy defects (OVDs) could be generated during the annealing treatment and the best photocatalytic efficiency was obtained when the annealing temperature was 450 °C. The enhanced photocatalytic efficiency was ascribed to the high separation efficiency of the photogenerated electron-hole pairs due to the existence of the OVDs as positively charged centers.
In this paper, NiCo2O4 nanoparticles were synthesized by three different methods. The applied preparation methods in this research are thermal decomposition of a mixed oxalate precursor, combustion synthesis and hydrothermal method. The crystalline phase, morphology and specific surface area (BET) of the resultant samples were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and nitrogen physical adsorption, respectively. The research found that the hydrothermal method is a promising method to prepare NiCo2O4 nanoparticles.
A series of Li[Ni0.8Co0.1Mn0.1]O2were synthesized with different [Ni0.8Co0.1Mn0.1](OH)2as precursors. Because the precursors were obtained via hydrothermal method at solutions with different ratios of ethanol and distilled water, they present different morphology in details. This phenomenon were inherited by the Li[Ni0.8Co0.1Mn0.1]O2. In addition, as-synthesized materials Li[Ni0.8Co0.1Mn0.1]O2perform distinct electrochemical properties as cathode materials in lithium-ion battery. The results indicate that more ethanol used in this work is effective to modify the surface structure of materials leading to better electrochemical properties. In addition, more ethanol in synthesis process could also improve the density of samples.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
