The research progress on the selective and sensitive fluorescent detection of nitrite anions has greatly relied on the development of new fluorescent materials. Herein, a novel nanohybrid exhibiting dual emissions in blue and red wavelength ranges is fabricated for the rapid, on-site, and sensitive detection of nitrite anions. Such a nanohybrid system consists of graphene oxide (GO-C6NH2) and g...

Nanohybrids represent a larger variety of functional materials consisting one or more types low-dimensional semiconductor nanostructures, such as quantum dots, nanowires, nanotubes, 2D atomic (graphene, transition-metal dichalcogenides, etc.) interfaced with another, and/or conventional material matrices (bulks, films, polymers, etc.). Heterojunction interfaces are characteristic in nanohybrids...

In the present contribution, a facile and efficient protocol for synthesis a nanohybrid structure of core-coronal-shell ZnO@ZIF-8 using ascorbic acid (ZnO@AA/ZIF-8) as a new adsorbent for arsenic removal from water has been represented. For this purpose, the ZnO nanospheres were synthesized by a green and simple method followed by coating with ascorbic acid (AA) to modify their surface to achie...

A nanohybrid was prepared with an inorganic clay material, montmorillonite (MMT), for taste masking of sildenafil (SDN). To further improve the taste-masking efficiency and enhance the drug-release rate, we coated the nanohybrid of SDN-MMT with a basic polymer, polyvinylacetal diethylaminoacetate (AEA). Powder X-ray diffraction and Fourier transform infrared experiments showed that SDN was succ...

A liposome-Ag nanohybrid has been demonstrated as a SERS traceable intracellular drug nanocarrier. Liposomes have been introduced for their special qualities in drug delivery systems. In essence, 4-aminothiophenol (4ATP) tagged Ag nanoparticles (Ag@4ATP) were adsorbed onto the surfaces of liposomes via electrostatic interactions, in which 4ATP was used as a SERS reporter. In such a nanohybrid, ...

STATEMENT OF PROBLEM Accumulation of plaque and staining due to a rough surface, and penetration of colourant agents from food and beverages in to the resin composite results in an incomplete polymerization. There is a little information on the effect of finishing and polishing techniques on the discoloration of nanohybrid and microhybrid composites when exposed to staining solutions. OBJECTI...

Carbon nanotubes (CNTs) have been the focus of extensive research in recent years due to their exceptional mechanical, thermal, and electrical properties (Treacy et al., 1996; Lourie et al., 1998; Yu et al., 2000; Lukic et al., 2005). As a result of their nanoscale dimensions and high surface area, CNTs could also be considered as efficient templates for the assembly and tethering of nanopartic...

The purpose of this study was to determine the influence of hydrochloric acid on surface roughness of composite resins subjected to brushing. Sixty samples measuring 2 mm thick x 6 mm diameter were prepared and used as experimental units. The study presented a 3x2 factorial design, in which the factors were composite resin (n=20), at 3 levels: microhybrid composite (Z100), nanofilled composite ...

A hybrid of nanomagnetic Fe3O4 and antibacterial nanomaterial such as Ag is one the promising nanoparticles for magnetoresistance-based biosensor. Therefore, we are developing a biosensor system to quantize biomolecule concentration via Fe3O4/Ag nanohybrid detection using spin-valve thin-film sensing element. In this research, magnetic was synthesized co-precipitation/aqua-solution method. Duri...

ABSTRACT In this paper, novel Nanohybrid CuO-Fe3O4/Zeolite nanocomposites (HCFZ NCs) have been synthesized to improve the adsorption capacity and activity for removing the Arsenic and Lead cations from the contaminated water solutions. The nanohybrid 4, 10, and 20 -HCFZ NC samples were investigated by XRD, FT-IR, TEM, FESEM, EDX, and BET. The characterization results of these catalysts confirm...
