The adsorption potential of empty cotton flower agro-residue based activated carbon (CFAC) to adsorb Reactive Orange 84 (RO84) dye from aqueous solution was studied using packed-bed adsorption column. The breakthrough curve characteristics were highly influenced by process variables like influen...

ABSTRACTThe effect of pigments having different chemical composition on the crystallization process of polypropylene, PP, was studied by means of differential scanning calorimeter in isothermal mode. Analysis of the experimental results was carried out using Avrami's equation to obtain the ...

Mold shrinkage of the colored plastics based on partially crystalline polymers is a well-known phenomenon and is assumed to be caused by pigment-induced crystallization of polymers. A systematic investigation has been carried out for a variety of organic pigments in polypropylene (PP) and polyet...

The use of lactose as a carbon source for the production of pigments by Monascus ruber was the aim of this study. 500-mL Erlenmeyer flasks containing 160 mL of culture medium with different substrates (glucose, lactose and hydrolyzed lactose) were incubated at 30 °C in shaker for 7 days. Produc...

Novel environment friendly inorganic hybrid pigments with bright red colors and good stability were successfully prepared by a one-pot hydrothermal reaction of natural attapulgite (APT) with Fe(III) salts, without addition of any chemical precipitants. It has been revealed by systematic structur...

In this study, we explore the molecular mechanisms of the stability of indigo chromophores and pigments. Assisted with density functional theory, we compare visible, infrared and Raman spectral properties of model molecules, chromophores and pigments derived from living organisms. Using indigo c...

Effect of high-humidity hot air impingement blanching on photochemical degradation kinetics (red pigments and ascorbic acid) and antioxidant capacity changes (2,2-diphenyl-1-picrylhydracyl, DPPH and total antioxidant capacity) of red pepper during 6-month storage at ambient temperature in dark w...

Two new scallop strains, the ‘QN Orange’ scallop and the ‘Bohai Red’ scallop, were selected from the hybrid cohort between the bay scallop (Argopecten irradians irradians) and the Peruvian scallop (Argopecten purpuratus) to improve the bay scallop stock, which has suffered from significant i...

A series of α-Fe2O3/palygorskite (α-Fe2O3/Pal) inorganic-inorganic composite pigments were prepared by a one-step hydrothermal process using six kinds of iron-rich natural palygorskite clays (Pal-c) with different structures, morphologies and compositions as starting materials. The effects of ...

The potential economic values and applications of natural yellow and red pigments in the food industry, cosmetic, and textile cannot be underestimated. So the improvement of a bioprocess for better production of Monascus pigments (MPs) using nutrition regulation under submerged fermentation was ...

In the study, a new vacuum method was applied to prepare the hybrid pigments of sepiolite and Basic red 46 (XL-GRL). Various hybrid pigments respectively prepared by the vacuum method, solid method and liquid method were compared. The obtained products were respectively labeled as VM, SM and LM....

Using a standard and modified europium chelate (Eu(TTA)3) and fluorescent brightener (FB) staining and microscopy procedure the suitability of the technique for studying the morphology of terrestrial and aquatic microorganisms was investigated. Cells of bacteria, yeasts, algae and protozoa were ...

Detection of optical brighteners by fluorometry combined with ultraviolet light (UV) exposure has been proposed as an inexpensive method for detection of human fecal contamination, but has received limited testing. This study evaluated the approach in southern California by applying it to a vari...

Two blue fluorescent 1,8-naphthalimide derivatives (fluorescent brighteners) having an allyloxy group have been investigated as modificators for polystyrene. It has been found that the monomeric fluorescent brighteners take part in the radical polymerization and are covalently bound to the polym...

Luminogens with the feature of aggregation-induced emission (AIE) are a class of ‘heterodox’ molecules, whose emissions are brightened by aggregate formation. The restriction of their intramolecular motions in an aggregate state is the main cause of the AIE process. In this account, we summari...

Three fluorescent brightening agents (FBA), imides of 4-methoxy-1,8-naphthalic anhydride, have been synthesized. The compounds contained, in the N-substituent, a triazine ring containing a substituent with a polymerizable centre, this allowing their copolymerization with styrene.

Over the last two decades fluorescent materials have strongly influenced the technological development of modern societies. Ranging from organic photovoltaic to OLED TVs, from highly sensitive early detection methods of diseases to the sensing of environmental pollutants, a multitude of applicat...

Multimodality molecular imaging has attracted more and more attention recently, as it possesses novel multiple imaging patterns via combining information from several independent molecular imaging techniques. Here, we investigated the multifunctional Mn2+ complex-modified polydopamine (PDA) and ...
