Background and purpose: Dyes from textile industry are amongst the major pollutants of the environment that are harmful for both human health and the environment. Azo dyes constitute the largest and the most important class of commercial dyes, accounting for 50% of all commercial dyes. This study investigated the efficacy of Cr-doped ZnO nanoparticles in removal of reactive black 5 (RB5) dye fr...

A combination of electron microscopy, focused ion beam and conductive atomic force microscopy techniques have been used to study the microstructure, oxide scale development, and electrical behavior of a Cu–9 at.% La alloy. The as-cast alloy exhibits a eutectic microstructure comprising 30 vol.% Cu rods in a Cu6La matrix. The eutectic colonies exhibit a singular orientation relationship with [01...

Sn doped CuO nanotubes were synthesized by thermal oxidization of Cu/SnO(2) core-shell nanowires in air through the Kirkendall effect. The Cu/SnO(2) core-shell nanowires were sequentially electrodeposited by forming a SnO(2) shell followed by electrodeposition of the Cu core. After thermal treatment in air, the core-shell Cu/SnO(2) (13 +/- 2 nm thick shell on 128 +/- 15 nm in diameter core) nan...

Iron(III)-doped silica nanoshells are shown to possess an in vitro cell-receptor mediated targeting functionality for endocytosis. Compared to plain silica nanoparticles, iron enriched ones are shown to be target-specific, a property that makes them potentially better vehicles for applications, such as drug delivery and tumor imaging, by making them more selective and thereby reducing the nanop...

The microstructure, precipitation kinetics, electrical conductivity, and mechanical properties of Cu-7.9 wt%Ag Cu-5.8 doped with 0.6 wt%Nb were investigated. As-cast microstructure revealed both discontinuous continuous Ag in Cu matrix. Differential scanning calorimetry data indicated that occurred at higher temperatures activation energy. Both micro-sized nano-sized Nb particles observed the N...

The effects of five nanomaterials (multiwalled carbon nanotubes [MWCNTs], Ag, Cu, ZnO, Si) and their corresponding bulk counterparts on seed germination, root elongation, and biomass of Cucurbita pepo (zucchini) were investigated. The plants were grown in hydroponic solutions amended with nanoparticles or bulk material suspensions at 1000 mg/L. Seed germination was unaffected by any of the trea...

A method of fluorescent nanoparticle-based indirect immunofluorescence microscopy (FNP-IIFM) was developed for the rapid detection of Mycobacterium tuberculosis. An anti-Mycobacterium tuberculosis antibody was used as primary antibody to recognize Mycobacterium tuberculosis, and then an antibody binding protein (Protein A) labeled with Tris(2,2-bipyridyl)dichlororuthenium(II) hexahydrate (RuBpy...

In this paper, a Cu, N co-doped TiO2 nanosheet with increased visible light photocatalytic activity was successfully synthesized using a biomimetic layer-by-layer deposition process. The polymer, branched-polyethyleneimine (b-PEI) was used as an induction agent for the hydrolysis of titanium bis(ammonium lactato)-dihydroxide (Ti-BALDH) as well as for a nitrogen resource, and the graphene oxide ...

In this article, a systematic study of the design and development of surface-modification schemes for silica nanoparticles is presented. The nanoparticle surface design involves an optimum balance of the use of inert and active surface functional groups to achieve minimal nanoparticle aggregation and reduce nanoparticle nonspecific binding. Silica nanoparticles were prepared in a water-in-oil m...

The synthesis and properties of an oxygen reduction catalyst based on a unique 3-dimensional (3D) nitrogen doped (N-doped) carbon composite are described. The composite material is synthesised via a two-step hydrothermal and pyrolysis method using bio-source low-cost materials of galactose and melamine. Firstly, the use of iron salts and galactose to hydrothermally produceiron oxide (Fe₂O₃) mag...
