Infrared spectra of trifluoroacetic acid (TFA) hydrates CF3COOH–(H2O)n have been observed in Ar matrix. A comparison of the spectra with theoretical calculations led us to the assignments of vibrational peaks for TFA–(H2O)n up to n = 4. The vibrational peaks of the zwitterion cluster, i.e. (CF...

Infrared absorption spectra of formic acid clusters (HCOOH)n have been observed in noble gas matrices (Ar, Kr and Xe). The concentration dependence of the spectra and a comparison with the assigned monomeric/dimeric bands has led to the assignment of polymeric species (HCOOH)n (n > 2). From comp...

EDTA modified β-cyclodextrin/chitosan (CDCS-EDTA) was fabricated successfully by a two-step method and applied to remove Pb(II) and anionic dye acid red 73 (AR). CDCS-EDTA was characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and zeta potential...

Light is an important environmental factor affecting plant growth and development. Additionally, HY5 is a central factor that coordinates light signal transduction and regulates the expression of flower color-related genes. However, there are few reports describing the co-regulation of apple fru...

The effect of temperature on the concentrations of anthocyanins and endogenous plant hormones [abscisic acid (ABA), auxin, and cytokinin] were investigated using the detached berries of two related red-skinned cultivars cv. ‘Aki Queen’ and ‘Ruby Roman’ of the table grape Vitis labrusca L. ×...

A novel bio–based polyurethane/chitosan foam (PU/chitosan) was synthesized using a polyol derived from castor oil and applied to remove Food Red 17 dye (FR17) from aqueous solutions. PU/chitosan foam presented better characteristics and adsorption potential than polyurethane foam (PU). PU/chito...

Anthocyanin pigments are suitable as natural dyes for food, cosmetics and dietary supplements, due to the demand for healthier products and their antioxidant properties. This work aimed to extract the anthocyanin pigments from red cabbage and its separation of the solution by adsorption operatio...

To improve the adsorption ability of polypyrrole(PPy), the cheap and readily available biological resources chitosan (CS) was introduced to synthesize PPy-CS composites that were uesed to remove Acid Red 18 (AR-18). The structure and morphology of PPy-CS (9:3) composites were characterized by sc...

Sm-doped CdS nanoparticles were synthesized through an ultrasound-assisted co-precipitation method and their photocatalytic efficiency was investigated by applying them to photodegradation of Acid Red 1 (AR1) under visible light. The effect of the operational factors on the photocatalytic proces...

The present study reports sonocatalytic activity of zinc sulfide-titanium dioxide nanotubes (ZnS-TNTs) in degradation of Acid Red 1 (AR1). Co-precipitation, hydrothermal and sonochemical methods were used to synthesize ZnS, TNTs and ZnS-TNTs, respectively. The physicochemical characteristics of ...

The massive accumulation of red gypsum has brought great harm to human and environment. In order to achieve low-cost and high-benefit resource utilization of red gypsum, a method of metal self-enrichment during the cycle and transformation of red gypsum was proposed. The carbon dioxide and ammon...

This research investigated the influence of lactic acid bacteria (LAB) strains on ester levels in Bordeaux red wines. These wines were made in five Bordeaux areas in two vintages, using three yeast strains. Malolactic fermentation (MLF) was carried out using industrial starters or indigenous str...

Immature rice grain is one of the underutilized by-products of paddy milling process. Despite its high potential of use as a food ingredient, it is mainly utilized as feed due to the rancidity problem. In the present study, the composition of immature rice grain, the potential of using infrared ...

Cumulative evidence has suggested that many antipsychotics cause metabolic abnormalities. Adipose tissue insulin resistance (Adipo-IR) contributes to the development and progress of metabolic abnormalities including fatty liver by inducing excessive free fatty acid release from adipose tissue. S...

Humic acid (HA) was isolated from lignite. Flocculent HA was made and used to adsorb and remove dye acid red 3R from aqueous solution. The adsorption experiments were carried out in a batch process to observe the effect of various parameters such as contact time, dose of flocculent HA, ionic str...

The main aim of this study was to apply capillary electrophoresis (CE) to the discrimination of red lipsticks – the first step towards developing the methodology for forensic purposes. The separation method was optimized using a mixture of eight dyes and micellar electrokinetic capillary chroma...

L-DOPA-induced dyskinesia (LID) remains a significant problem in the management of Parkinson's disease (PD). In rodent and macaque models of PD, delta opioid receptor agonists have anti-parkinsonian actions while mu opioid antagonists can reduce the expression of LID. DPI-289 is a novel mol...

Physicochemical characteristics and phytochemical profiles of red (Physalis alkekengi L., RP) and yellow (P. pubescens L., YP) Physalis fruits cultivated in three provinces of China were characterized. YP fruits showed significantly lower levels of total organic acids and elevated total sugars t...

Ganoderic Acids (GAs) are the major medicinal compounds in Ganoderma lucidum used as traditional Chinese medicine since ancient times.
