TL;DR: The result reveals that after intratumoral injection of CuS@QCS-NPs with NIR laser irradiation, the 4T1 mammary tumor growth could be effectively suppressed comparing with the other control groups, and there was no obvious lethal toxicity to liver function, kidney function, and vital organs.

TL;DR: A facile and efficient synthetic route toward highly substituted 2,3-dihydrothiopyran-4-ones 2 has been developed via a formal annulation of readily available alpha-alkenoyl ketene-(S,S)-acetals with sodium sulfide nonahydrated salt.
Abstract: A facile and efficient synthetic route toward highly substituted 2,3-dihydrothiopyran-4-ones 2 has been developed via a formal [5C + 1S] annulation of readily available α-alkenoyl ketene-(S,S)-acetals 1 with sodium sulfide nonahydrated salt (Na2S·9H2O) and utilized in the synthesis of 2-(4-chlorophenyl)-6-(morpholin-4-yl)-4H-thiopyran-4-one 5l, an inhibitor of DNA-dependent protein kinase (DNA-PK).

07 Nov 1994TL;DR: In this paper, a method for encapsulating and stabilizing radioactive, hazardous and mixed wastes in a modified sulfur cement composition is presented. But the method is not suitable for the handling of large quantities of waste.
Abstract: The present invention provides a method for encapsulating and stabilizing radioactive, hazardous and mixed wastes in a modified sulfur cement composition. The waste may be incinerator fly ash or bottom ash including radioactive contaminants, toxic metal salts and other wastes commonly found in refuse. The process may use glass fibers mixed into the composition to improve the tensile strength and a low concentration of anhydrous sodium sulfide to reduce toxic metal solubility. The present invention preferably includes a method for encapsulating radioactive, hazardous and mixed wastes by combining substantially anhydrous wastes, molten modified sulfur cement, preferably glass fibers, as well as anhydrous sodium sulfide or calcium hydroxide or sodium hydroxide in a heated double-planetary orbital mixer. The modified sulfur cement is preheated to about 135°±5° C., then the remaining substantially dry components are added and mixed to homogeneity. The homogeneous molten mixture is poured or extruded into a suitable mold. The mold is allowed to cool, while the mixture hardens, thereby immobilizing and encapsulating the contaminants present in the ash.

TL;DR: Sodium sulfosalicylate was used for the first time to enhance the sulfidation-flotation of smithsonite in this article, which improved the flotation performance by 3.83% and the concentrate recovery by 7.63%.
