A sonochemical method for the selective synthesis of a-HgS and b-HgS nanoparticles
A novel sonochemical method for the selective synthesis of a-HgS (cinnabar) and b-HgS (metacinnabar) nanoparticles in aqueous solutions is reported in this paper. a-HgS and b-HgS nanoparticles have been selectively prepared by choosing sodium thiosulfate and thiourea as the sulfur source respectively. To study the crystalline structure, size, morphology and composition of the products, characte...
متن کاملPhase transfer-based synthesis of HgS nanocrystals.
Phase transfer techniques possess remarkable advantages for the synthesis of inorganic nanomaterials. In contrast to the abundant reports on the preparation of noble metal nanoparticles using phase transfer, the number of semiconductor nanocrystals syntheses based on phase transfer techniques is still limited. Herein, we report a systematic study of the phase transfer-based synthesis of HgS nan...
متن کاملThe synthesis of HgS microcrystallites with controllable structure and morphology
Rod-like and spheric mercury sulfide (HgS) microcrystallites with hexagonal and cubic structure have been synthesized at room temperature by treating HgO with sulfur in ethylenediamine (en). Real time monitoring of both the UV–vis absorption spectrum and Raman spectrum during the dissolution process of sulfur in en solvent have been exploited for the first time to explore the underlying reactio...
متن کاملAntibody-biotemplated HgS nanoparticles: extremely sensitive labels for atomic fluorescence spectrometric immunoassay.
In this work, antibody goat anti-human IgG as a scaffold was employed for the synthesis and biofunctionalization of HgS nanoparticles (NPs) via a facile one-pot process. After a complete sandwich-type immunoreaction among primary antibody, human IgG and secondary antibody labeled with HgS NPs, a large number of mercury ions released from captured HgS NPs dissolution were quantitatively detected...
متن کاملSynthesis and Characterization of α-Fe2O3 Nanoparticles by Microwave Method
α-Fe2O3 (hematite) is the most stable iron oxide under ambient conditions. This transition metal oxide has been extensively investigated because it has unique electrical and catalytic properties. In this report, a novel microwave method for preparation of α-Fe2O3 nanoparticles has been developed. The process contained two steps: first, precursor were obtained from a mixed solution of 50 ml of 0...
