Equation of Berendsen and de Golan permitted to establish adsorption isotherms on the basis of chemical composition of the stu...

Studies were carried out to isolate Acid red 119 (AR-119) resistant and decolourising bacteria from dye contaminated soil and water samples. Six morphologically distinct bacterial isolates resistant to 100 ppm AR-119 dye were isolated directly from the soil and waste contaminated with azo dyes. ...

This study investigated the evolution of the middle reach of the Yellow River by examining the latest Cenozoic (∼5.0–0.15 Ma) sedimentary history of the Weihe and Sanmenxia basins in the Weihe region of North China. Although the development of the two basins and the evolution of the Yellow Riv...

A low cost activated carbon was prepared from agricultural waste, peanut shells (PnsAC), using H3PO4 followed by pyrolysis at 650 °C under nitrogen environment and used as a precursor to remove Acid Yellow 36 (AY-36) dye from wastewater. Batch experiments were conducted to study the effects of ...

The present study investigated the growth performance, intestinal morphology, body composition and organoleptic quality of large yellow croaker Larimichthys crocea fed a diet containing different proportions of Antarctic krill Euphausia superba meal (0, 15, 30, 45, 60 and 75%) as a substitute fo...

Dispersibility is an important property of pigment, it determines whether the pigment primary particles are wetted and well-spaced giving optimum tinctorial strength. As Isoindolinone yellow pigment (Color index Number: Pigment Yellow 110, Molecular formula C22H6Cl8N4O2) is an expensive pigment,...

New series of brilliant yellow colorants with high NIR reflectance in rare earth doped scheelite type oxides, [(LiRE)0.125Bi0.75][W0·25V0.75]O4 (RE = La–Yb) and [(LiLa)x/2Bi1-x][WxV1-x]O4 (x = 0–0.3) were developed by the ceramic route. Different advanced techniques were used to examine the s...

In this study, the green nanoceria (GN) was synthesized from Prosopis juliflora (Sw.) leaves extract, then amine functionalized to GNNH2 (AGN) with epichlorohydrin and ammonium hydroxide. The synthesized GN and AGN were characterized by FT-IR, zeta potential, XRD, BET model and.HR-TEM. Sequentia...

Lead halide perovskites exhibit unexceptionable photoelectric properties. However, these materials are unsatisfactory in terms of stability and toxicity. Herein, we report Rb7Sb3Cl16 as a new kind of lead free perovskite variants. This material can be easily obtained through hydrothermal reactio...

Nanofiltration (NF) (MWCO 150–300 Da) was evaluated for the recovery of phenolic compounds from the wastewater from the production of yellow mustard protein isolates. Rejection coefficients of 0.70 and 0.87 and transmembrane fluxes of 51.3 L/hm2 and 28.8 L/hm2 were observed under alkaline and a...

This study presents unpublished data on the chlorogenic acid and caffeic acid content in fruits. Sixty-four fruits consumed in Brazil, most of which were produced domestically, were evaluated based on their levels of 3-caffeoylquinic acid, 4-caffeoylquinic acid, 5-caffeoylquinic acid, 3,4-dicaff...

A simple and highly-available air-assisted dispersive liquid-liquid microextraction procedure with organic phase solidification (AA-DLLME-OPS) was developed as new approach for pretreatment of complex sample matrix. Menthol was investigated as novel extractant for the AA-DLLME-OPS. In this proced...

In the present study, we introduced point mutations into Ac_rapA which encodes a polyketide synthase responsible for rapamycin biosynthesis in Actinoplanes sp. N902-109, in order to construct a mutant with an inactivated enoylreductase (ER) domain, which was able to synthesize a new rapamycin an...

Violets of the section Melanium from Albanian serpentine and chalk soils were examined for their taxonomic affiliations, their ability to accumulate heavy metals and their colonization by arbuscular mycorrhizal fungi (AMF). The sequence analysis of the ITS1-5.8S rDNA-ITS2 region showed that all ...

Rod-like zinc oxide (ZnO) nanopowder was synthesized from zinc acetate via an ultrasound assisted non-hydrolytic sol–gel process. The samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and UV–vis spectroscopy. X-ray diffraction confirmed that the as-p...

In this study, the interaction between C.I. Acid Orange 7 (AO7) and human serum albumin (HSA) was firstly investigated using nuclear magnetic resonance (NMR) spectroscopy in combination with fluorescence quenching spectroscopy, three-dimensional fluorescence spectroscopy, UV–vis absorption spec...

The interactions between C.I. Basic Yellow 2 (BY2) and sodium dioctylsulfosuccinate (NaDS) have been investigated in the premicellar and micellar region using spectrophotometric method at 288.15, 298.15, 308.15 and 318.15 K. Absorption spectra of dye–surfactant mixtures show that dye–surfactan...
