And the article contained the following:

The complex rheol. response of chocolates of different compositions was analyzed in depth from stationary shear flow curves and large amplitude oscillatory shear tests. The samples have a wide range of cocoa content that controls the rheol. behavior characterized by a yielding response. The strain amplitude at which the chocolates changed from elastic-dominated to viscous-dominated behavior ranged from 0.2 to 0.4%. In this region, the stress response to the applied sinusoidally oscillating shear strain showed transient overshoots whose values were similar to yield stress calculated using the Casson equation in continuous flow. The nonlinear response at the steady-state was analyzed. The Q0 nonlinearity parameter, obtained from Fourier Transform anal., increases as the concentration of the solids conferring bimodality to the particle size distribution increases. In the study of intracycle nonlinearities, the anal. of the third-order Chebyshev elastic and viscous coefficients showed that the sample which contains the highest amount of solids different from cocoa exhibited the lowest strain-stiffening and the highest shear-thinning behaviors. Stress bifurcation anal. identified the beginning of the yielding transition and evidenced a nonlinear solid-like behavior before the solid-liquid transition. Anal. of Lissajous-Bowditch curves allowed the static and dynamic contributions of the yielding transition to be identified, and the full Sequence of Phys. Process quant. anal. captures the time-dependent nonlinear response of chocolates over the history of applied deformations. The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).Safety of SweetPearlR P300 DC Maltitol

On December 31, 2020, Kozlowicz, Katarzyna; Rozylo, Renata; Gladyszewska, Bozena; Matwijczuk, Arkadiusz; Gladyszewski, Grzegorz; Chocyk, Dariusz; Samborska, Katarzyna; Piekut, Jolanta; Smolewska, Marzena published an article.Product Details of 621-37-4 The title of the article was Identification of sugars and phenolic compounds in honey powders with the use of GC-MS, FTIR spectroscopy, and X-ray diffraction. And the article contained the following:

This work aimed at the chem. and structural characterization of powders obtained from chestnut flower honey (HFCh) and honey with Inca berry (HBlu). Honey powders were obtained by spray drying technique at low temperature (80/50 °C) with dehumidified air. Maltodextrin (DE 15) was used as a covering agent. The isolation and evaluation of phenolic compounds and sugars were done by gas chromatog.-mass spectrometry anal. SEM, Fourier-transform IR (FTIR) spectroscopy, and X-ray diffraction were performed to determine the morphol. of the studied honey powders. The obtained results showed that the content of simple sugars amounted to 72.4 and 90.2 g x 100 g-1 in HFCh and HBlu, resp. Glucose was found to be the dominant sugar with a concentration of 41.3 and 51.6 g x 100 g-1 in HFCh and HBlu, resp. 3-Phenyllactic acid and ferulic acid were most frequently found in HFCh powder, whereas m-coumaric acid, benzoic acid, and cinnamic acid were the most common in HBlu powder. The largest changes in the FTIR spectra occurred in the following range of wavenumbers: 3335, 1640, and below 930 cm-1. The X-ray diffraction profiles revealed wide peaks, suggesting that both honey powders are amorphous and are characterized by a short-range order only. The experimental process involved the reaction of 3-Hydroxyphenylacetic acid(cas: 621-37-4).Product Details of 621-37-4

On February 28, 2019, Shoukat, Usman; Baumeister, Eva; Pinto, Diego D. D.; Knuutila, Hanna K. published an article.Electric Literature of 2160-93-2 The title of the article was Thermal stability and corrosion of tertiary amines in aqueous amine and amine-glycol-water solutions for combined acid gas and water removal. And the article contained the following:

Thermal stability and corrosion of seven tertiary amines (20 weight%) solutions in water and water-glycol [ethylene glycol (MEG)/tri-ethylene glycol (TEG)] loaded with CO2 in stainless steel reactors has been studied for combined acid gas removal along with hydrate control. The pKa of the tested amines varied from 7.85 to 9.75. Titration and inductivity coupled plasma mass spectrometry (ICP-MS) are used to quantify the remaining alkalinity and metal concentrations in amine solutions resp. The presence of MEG and TEG profoundly influenced the amine stability. Triethanolamine had the highest thermal stability. Furthermore, the results also show that an increase in pKa generally decreases corrosion. 3-(Diethylamino)-1,2-propanediol (DEA-1,2-PD) has the lowest corrosion in water and water-TEG solutions while 2-(Diethylamino)ethanol (DEEA) has the least corrosion in water-MEG solutions The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Electric Literature of 2160-93-2

On July 31, 2021, Ahmad, K. S.; Hafeez, N.; Gul, M. M.; Ali, D.; Shaheen, A.; Aslam, B. published an article.HPLC of Formula: 96-76-4 The title of the article was Xenobiotic thiencarbazone-methyl biotransformation investigation by bacteria Streptococcus pneumoniae, Escherichia coli and Streptococcus pyogenes. And the article contained the following:

Abstract: Xenobiotic thiencarbazone-Me is a herbicide applied on various grasses and weeds. This triazolinone pesticide may be present in soil and water after application posing deleterious effects on environment and human health. The degradation of thiencarbazone-Me was scrutinized by the pure bacterial strains including Streptococcus pneumoniae (SP), Escherichia coli (EC) and Streptococcus pyogenes (SPy). Individual bacterial suspension was prepared with herbicide solution and evaluated for a duration of 28 days. Time-dependent sampling was performed to investigate thiencarbazone-Me degradation after specific days interval. Biotransformed samples were extracted and analyzed by UV-Vis spectrophotometer and GC-MS. Biodegradation percentage achieved by SP, Spy and EC, after 28 days, was 31, 40 and 65, resp. E. coli (R2= 0.91) displayed greatest potential among all the strains to degrade the herbicide. Significant residues formed included Me 4-isocyanatosulfonyl-5-methylthiophene-3-carboxylate, 4-methanesulfonyl-benzenesulfonic acid amide and Me 3-sulfamoylthiophene-2carboxylate. Current research elucidated the effectiveness of using bacterial strains for the bioremediation of pesticides in environment. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).HPLC of Formula: 96-76-4

On October 31, 2021, Lewis, Kathy; Tzilivakis, John published an article.Formula: C12H24O11 The title of the article was Review and synthesis of data on the potential environmental impact of artificial sweeteners. And the article contained the following:

A review. EFSA is implementing evidence-based risk assessments for the re-evaluation of certain sweeteners. The aim of this work was to ensure that, as part of the preparatory work done by EFSA to support its Panel on Food Additives and Flavourings (FAF) in reaching conclusions on the safety of permitted food additives, relevant information on the environmental risks associated with the use of the artificial sweeteners are identified. In the context of this re-evaluation process the following substances used as sweeteners were considered: acesulfame-K (E 950), salt of aspartame-acesulfame (E 962), sucralose (E 955), saccharins (E 954), thaumatin (E 957), neohesperidine DC (E 959), neotame (E 961), cyclamates (E 952) and the polyol sweeteners (sorbitols (E 420); mannitol (E 421); isomalt (E 953); maltitols (E 965); lactitol (E 966); xylitol (E 967) and erythritol (E 968)). Data was collated using a systematic review approach. Generally, the data identified was extremely limited particularly with respect to neohesperidine DC, neotame, thaumatin and the polyol sweeteners. However, there was also limited evidence to suggest their widespread occurrence in the environment. With respect to acesulfame-K, sucralose, cyclamates and saccharin multiple studies were identified that demonstrate the widespread distribution of these sweeteners in surface waters, groundwaters, coastal and marine waters. There are also studies showing their presence in drinking (tap) water supplies, rainwater and in atm. samples. However, these sweeteners do not appear to be highly toxic to aquatic species, at least not at environmental concentrations currently seen. The salt of aspartame-acesulfame easily dissociates into its two component sweeteners in the human body and the environment and so the review process also considered aspartame despite it not being a specific focus of the regulatory review process. While there is some evidence to suggest aspartame is toxic to aquatic species it is not detected at levels of concern in the environment. The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).Formula: C12H24O11

Wang, Peng; Gu, Xuefan; Wang, Quande; Dong, Jianlong; Dong, Sanbao; Zhang, Jie; Zhu, Shidong; Chen, Gang published an article in 2021, the title of the article was Corrosion inhibition of triazines in sulfur-containing oilfield wastewater.Application of 4719-04-4 And the article contains the following content:

In this study, three kinds of triazines were synthesized via a condensation reaction to inhibit corrosion in oilfield wastewater. The prepared triazines were characterized by IR spectroscopy and gas chromatog.-mass spectrometry, and their performance as eco-friendly corrosion inhibitors in sulfur-containing oilfield wastewater was subsequently evaluated using the weight-loss method and solid-liquid adsorption theory. The results exhibited that triazine II was the most effective corrosion inhibitor in the three and the maximum inhibition efficiency of triazine II (800 mg L-1) can reach 97.66%. The adsorption of the inhibitor was consistent with the assumption of Langmuir adsorption isotherm, the process was spontaneous and chem. adsorption. The mechanism of corrosion inhibition was further explained by desulfurization reaction and coordination bond theory, indicating triazines can be a desulfurizer to synergize their corrosion inhibition in sulfur-containing oilfield wastewater. And their easy adsorption on the steel surface is attributed to nitrogen and oxygen atoms with isolated electron pairs. The above exptl. results all indicate that they have the excellent performance to inhibit corrosion, which can be used in oilfield wastewater treatment and will benefit the related research. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Application of 4719-04-4
