The distribution and quality of water resources vary dramatically across Canada, and human impacts such as land-use and climate changes are exacerbating uncertainties in water supply and security. At the national level, Canada has no enforceable standards for safe drinking water and no comprehen...

In recent years, increasing eutrophication in large freshwater lakes, which are an important drinking water source for cities in China, have been resulted in substantial cyanobacteria blooms that could cause serious taste and odor (T&O) problems. In this investigation, three typical lakes (Songh...

An important problem encountered during the preservation of paintings and other artworks is the fading of the original colors due to exposure of the colorants to light. This fact is clearly evidenced in some of Vincent Van Gogh's paintings in which an organic red, eosin or geranium lake, is...

The Blue Economy (BE) is rapidly becoming one of the most commonly applied regional economic paradigms in coastal and maritime regions globally. Since the late 1970s, the U.S. Great Lakes basin has searched for ways to reverse its economic decline, and the BE offers new opportunities to sustain ...

Bismuth tungstate (Bi2WO6) flake-like nanostructures with zigzag periphery and 30–40 nm thickness in high yield were produced by facile and efficient modified hydrothermal technique. The as-synthesized nanostructures were characterized by X-ray diffraction (XRD), energy dispersive x-ray spectro...

At least 30 different human proteins can fold abnormally to form the amyloid deposits that are associated with a number of degenerative diseases. The research presented here aimed at understanding the inhibitory potency of a food additive, brilliant blue FCF (BBF), on the amyloid fibril formatio...

Grafting of poly(para-, ortho- and meta-phenylenediamine (PPDA)) onto electrospun carbon nanofibers was performed via oxidative polymerization of o-, p-, m-PDA onto the surface of ECNFs to produce PPDA-g-ECNFs. The well characterized PPDA-g-ECNFs and their precursors were applied as effective na...

With the widespread application of synthetic pigments in the food industry, food safety incidents caused by illegal addition of pigments have become more frequent. In this study, we synthesized core–shell nanomaterials for use in sensitive, fast, convenient, nondestructive detection and having ...

To assess the cellular stress evoked by exposure of Brilliant Blue-G (BBG), adult retinal pigment epithelial (ARPE-19) cells were treated with various dilutions of BBG in balanced salt solution plus (BSS-PLUS) with and without endoillumination (Alcon Constellation Vision System). The treatments ...

The efficiency of methods to reduce the pollution induced by dyes is often evaluated using a color change measurement. This approach might hide complex mechanisms, that, if neglected, can lead to inadequate design of treatment units. This paper highlights this complexity on the case of Remazol B...

The present work deals with the preparation of WO3 and WO3-ZnO nanocomposites in presence of ultrasonic irradiation, and its use in the sonocatalytic degradation of brilliant blue dye. WO3-ZnO nanocomposite is prepared using one step in-situ ultrasound assisted method. The successfully prepared ...

Single-component dual-emission nanoparticles were synthesized by chelating the organic ligand 8-hydroxyquinoline (HQ) to the surface of CdTe/ZnS quantum dots, namely CdTe/ZnQ2, and were used to construct a novel mesoporous structured molecular imprinting ratiometric fluorescence sensor by facile...

The Blue Economy is an ocean based economic growth model gaining traction around the world. The way in which the Blue Economy is conceived and understood differs significantly across different sets of actors. A particular area of contestation exists around which ocean based industries or sectors...

Some strains of the Bacillus cereus group can be implicated in two types of foodborne intoxication syndromes, namely diarrheal and emetic. The emetic syndrome results from the ingestion of the cereulide toxin produced by particular strains of B. cereus and Bacillus weihenstephanensis. It represe...

A 3D copper−organic framework of HKUST-1 (MOF-199) was synthesized via solvothermal reaction of Cu(NO3)2∙3H2O and 1,3,5-Benzenetricarboxylic acid (BTC) according to literature methods. HKUST-1 was further sensitized by adsorbing trichromatic dyes photosensitizers of BY24 (C. I. Basic Yellow 24),...

Phototropin (phot)-mediated signaling initiated by blue light (BL) plays a critical role in optimizing photosynthetic light capture at the plasma membrane (PM) in plants. However, the mechanisms underlying the regulation of phot activity at the PM in response to BL remain largely unclear. In thi...

This paper presents a laboratory study of the relation between blue whirls and fire whirls in terms of circulation (swirl) and energy-release rate. The blue whirl is a small, completely blue, soot-free flame that was originally seen when it evolved from more traditional fire whirls burning liqui...

PurposeTo evaluate the role of toluidine blue (TB) staining patterns in diagnosis of ocular surface squamous neoplasia (OSSN) in comparison to that of impression cytology.

Water bodies throughout the world are severely affected by the discharge of industrial effluents contaminated with xenobiotic and recalcitrant substances. Due to the low biodegradability of these compounds, conventional treatments have proven to be insufficient for their removal. Although hetero...

Two ammonium oxofluorovanadates, (NH4)3VO2F4 and (NH4)3VOF5, have been investigated by temperature-dependent infrared and Raman spectroscopy methods to determine the nature of phase transitions (PT) in these compounds. Dynamics of quasioctahedral groups was simulated within the framework of semi...
