Investigation of the intrinsic reaction kinetics and the mass transfer phenomena of nonanoic acid esterification with 2-ethylhexanol promoted by sulfuric acid or Amberlite IR120

Nonanoic acid is obtained as main coproduct in the synthesis of azelaic acid from oleic acid. The increase of azelaic acid production, being a monomer useful to synthesize biodegradable polyesters, lead to a high availability of nonanoic acid, that can be used as feedstock in esterification reactions to obtain lubricants and solvents. In this work, the esterification of nonanoic acid with 2-ethylhexanol to produce a solvent were conducted in a batch reactor in the presence of either a homogeneous (H2SO4) or an heterogenous catalyst (Amberlite IR120). The intrinsic reaction kinetics was investigated by considering all the physical and chemical phenomena occurring in the reaction network, leading to the determination of thermodynamic and kinetic parameters. The activation energy values of both catalysts are similar (approximate to 60 kJ/mol) and the enthalpy value of Delta H-r = 10.3 kJ/mol showed that the reaction is slightly endothermic. The reaction is shifted to the products as demonstrated by the reference equilibrium constant equal to 1.69 at 333 K. The obtained results will be useful to design industrial reactors.

Effective degradation of tetracycline via polyvinyl alcohol /Bi2WO6 hybrid hydrogel with easy separation

Developing inexpensive and stable photocatalysts with easy separation for the degradation of antibiotics is highly needed. In this study, a three-dimensional poly(vinyl alcohol) (PVA)/Bi2WO6 (BWO) (PVA/BWO) hybrid hydrogel photocatalyst with easy separation was constructed via freeze-thaw process and then was used to remove Tetracycline (TC) from water. The obtained hydrogels were characterized by various techniques. SEM image and EDS mapping show the successful decoration of BWO and the BWO is homogenously distributed on the PVA substrate. Results of the photocatalytic experiment and total organic carbon content (TOC) measurement show that the constructed PVA/BWO hydrogel could degrade TC effectively under visible light irradiation, even after the PVA/BWO hydrogel had been recycled for five times. Results of XRD, SEM and EDS mapping on the fresh and used PVA/BWO hydrogel confirm its relatively good stability in structure. The possible reaction pathways and mechanism of TC degradation were also analyzed. The PVA/BWO hybrid hydrogel with easy separation could be a new alternative with great potential in efficient removal of persistent organic pollutants.

Strategies to utilize naturally occurring protein architectures as nanovehicles for hydrophobic nutraceuticals

The development of protein-based nanovehicles to improve water solubility, stability and bioavailability of hydrophobic or poorly soluble nutraceuticals has become a subject of fast increasing interest in the field. This review mainly presents the state-of-art knowledge about the utilization of naturally occurring nanostructured protein architectures (casein micelles, ferritin and legume oligomeric globulins) as nanovehicles for hydrophobic nutraceuticals or drugs, through a disassembly and reassembly strategy. First, the composition and structural features of these three naturally occurring architectures are briefly summarized. Then, many strategies and techniques to mediate the disassembly and reassembly of these naturally occurring architectures are comprehensively reviewed, including pH-, urea-, alcohol-, high pressure-, and heat-mediated disassembly and reassembly (or dissociation and reassociation). Last, reassembled casein micelles, ferritin (or apoferritin) and legume oligomeric protein nanoparticles are demonstrated to perform as outstanding nanovehicles for improving water dispersion, stability and bioactivities of many nutraceuticals or drugs. Due to the rapidly increasing consumer interests for health-benefiting foods, this review is of importance for the development of a kind of outstanding nanovehicles for nutraceuticals with a great potential to be applied in functional foods or drug formulations.

Reducing the destructive effect of ambient humidity variations on gas detection capability of a temperature modulated gas sensor by calcium chloride

Despite the successful detection performance of electronic nose in laboratories, they face challenges for use in the industry due to their accuracy reduction resulted from variable ambient properties especially relative humidity (RH) variation which is studied here. Responses of a single temperature modulated metal oxide gas sensor have been analyzed by SVM and k-NN methods to achieve a detector for low concentration levels of acetone, ethanol, 1-propanol and 1-butanol in air. The classifier models were designed and tested under different train-test conditions which showed that studied gases can be detected by the classifier if only they were measured in the same train and test environmental conditions and deviation of humidity level from train condition, reduces the detection accuracy to less than 60%. The accuracy increases by expanding the training dataset and training the system with responses carried out for gas with various RH contents. It was also shown that by using CaCl2 at the rout of gas flow, the destructive effect of RH variation is reduced and the detection accuracy increases to above 90%, while to achieve this accuracy, it is not necessary to train the system in all humidity conditions. By this method, the number of required test for system training reduces drastically. The method can be generalized to other electronic nose and gas detectors which suffer from humidity variations.

Sedentary behaviour in cardiovascular disease patients: Risk group identification and the impact of cardiac rehabilitation

Background: Sedentary behaviour (SB) is potentially an important target to improve cardiovascular health. This study 1) compared SB between cardiovascular disease (CVD) patients and age-matched controls, 2) identified characteristics associated with high SB levels, and 3) determined the impact of contemporary cardiac rehabilitation (CR) on SB. Methods: For objective 1, we recruited 131 CVD patients and 117 controls. All participants were asked about their general characteristics and medical history. SB was assessed by an objective accelerometer (activPAL3 micro). For objective 2, 2584 CVD patients were asked to fill in a questionnaire about their general characteristics, lifestyle, medical history and their SB. For objective 3, 131 CVD patients were followed over time and measured, pre-, directly post- and 2 months post-CR. Results: Objective 1. CVD patients spent 10.4 h/day (Q25 9.5; Q75 11.2) sedentary which was higher compared to healthy controls (9.4 h/day [Q25 8.4; Q75 10.29]). Objective 2. CVD patients being male, single or divorced, employed, physically inactive, reporting high alcohol consumption, living in an urban environment, having comorbidities and cardiac anxiety demonstrated a greater odds for large amounts of SB. Objective 3. The CR program significantly reduced sedentary time (-0.4 h/day [95%CI-0.7; -0.1]), which remained lower at 2-months post-CR (-0.3 h/day 195%CI -0.6; -0.03]). Conclusions: CVD patients had greater amounts of objectively measured sedentary time compared to healthy controls. Sedentarism was associated with personal- and lifestyle characteristics, and comorbidities. Participation in a contemporary CR program slightly reduced sedentary time, but tailored interventions are needed to target SB in CVD patients. (C) 2020 The Authors. Published by Elsevier B.V.

Social interaction anxiety and perceived coping efficacy: Mechanisms of the association between minority stress and drinking consequences among sexual minority women

Sexual minority women (SMW; individuals who identify as women and as lesbian, bisexual, or with another sexual minority identity) are at increased risk for problematic alcohol use compared to their heterosexual counterparts. This increased risk has been attributed to minority stress. However, longitudinal research examining associations between minority stress and alcohol use outcomes is extremely limited and examinations of these associations at the daily level are nearly non-existent. Further, few longitudinal studies have examined mechanisms through which minority stress may impact alcohol use. We utilized data from a 14-day daily diary study of 98 SMW to examine daily-level associations between experiences of minority stress, alcohol consumption and consequences, and two proposed mediators of these associations (perceived coping efficacy, social interaction anxiety). Results indicated that on days when participants experienced minority stress events, they experienced lower coping efficacy, higher social interaction anxiety, and more drinking consequences than usual. Minority stress was not associated with same-day alcohol consumption. Perceived coping efficacy and social interaction anxiety mediated the same-day association between minority stress and drinking consequences. No prospective associations were significant, suggesting that studies with multiple assessments per day may be necessary to detect immediate effects of minority stress. Findings highlight the potential impact of daily experiences of minority stress on alcohol consequences and provide evidence that two general psychological processes may be mechanisms through which minority stress impacts alcohol consequences. These results provide evidence of a need for interventions that teach SMW skills for coping with minority stress and its psychological consequences.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 2516-33-8. Safety of Cyclopropylmethanol.

Distinct paths to alcohol problems: Impacts of childhood maltreatment, attachment insecurity, and interpersonal problems

Childhood maltreatment is a strong risk factor for increased alcohol use and alcohol-related problems. One possible explanation for these associations is the influence of dysfunctional attachment styles and interpersonal problems in adulthood. Individuals who have experienced childhood maltreatment are likely to develop maladaptive interpersonal styles due to insecure attachment. Maladaptive interpersonal styles may increase emotional distress, which in turn, can make these individuals vulnerable to alcohol use and alcohol-related problems. Using data from 508 undergraduate students, this study examined the associations between three types of childhood maltreatment (i.e., sexual abuse, punishment that included physical abuse, and a negative home atmosphere that included neglect), alcohol use, and alcohol-related problems via insecure attachment and interpersonal problems. The results showed that punishment predicted alcohol problems via avoidant attachment and selfish interpersonal style. Sexual abuse and negative home atmosphere predicted alcohol consumption through anxious attachment and selfless interpersonal style. In addition, sexual abuse directly predicted alcohol problems. These findings provide new insights for the field of childhood maltreatment and addiction literature.

Gastrodin alleviates seizure severity and neuronal excitotoxicities in the rat lithium-pilocarpine model of temporal lobe epilepsy via enhancing GABAergic transmission

Ethnopharmacological relevance: Temporal lobe epilepsy remains one of the most drug-resistant focal epilepsy, leading to enormous healthcare burden. Among traditional herb medicine, some ingredients have the potential to treat seizure and alleviate the neuronal excitoxicity. The dried rhizome of Gastrodia elata Blume has been used to treat convulsive disorder, dizziness, dementia and migraine in eastern Asia. Aim of the study: To determine whether gastrodin, an active ingredient of Gastrodia elata Blume, can reduce lithium-pilocarpine induced seizure severity and neuronal excitotoxicity and explore the underlying mechanism. Materials and methods: We divided the Sprague-Dawley rats into an experimental group (gastrodin group) and a control group (Dimethyl sulfoxide, vehicle group) and performed the behavioral analysis and electroencephalography to determine the effect of gastrodin on the seizure severity induced by lithium-pilocarpine injection. Nissl-stained histopathology elucidated the degree of rat hippocampal neuronal damage as markers of acute and subacute neuronal excitotoxicity. Besides, the Western blotting of dissected hippocampus was carried out to demonstrate the protein expression involving GABAergic transmission and metabolic pathway. Results: Gastrodin reduced the acute seizure severity in lithium-pilocarpine-induced seizure model. In electroencephalography recording, gastrodin exerted inhibitory action on epileptiform discharge. Compared with control group, gastrodin exhibited neuroprotective effect against seizure related hippocampal neuronal damage at acute and subacute stages. The Western blotting showed that gastrodin reversed the degradation of GABA(A) receptor after pilocarpine-induced seizures. Conclusions: In the experimental seizure model, gastrodin showed anti-seizure and neuroprotective abilities. Enhancing the expression of GABA(A) receptor plays an important role in its antiepileptic mechanism. The results offer a new insight of developing new antiepileptic drugs from traditional Chinese medicine.

Structure and functionality of oat protein extracted by choline chloride-dihydric alcohol deep eutectic solvent and its water binary mixtures

This research reports an eco-friendly oat protein extraction method using choline chloride (ChCl)-butanediol deep eutectic solvents (DESs) and DES/water binary mixtures. Eighteen formulas consisting of ChCl with butanediol isomer (1,2-butanediol, 1,4-butanediol, or 2, 3-butanediol) in the absence or presence of water at different molar ratio were examined for the synthesis of DESs and binary mixtures. We found that 6 formulae can be fabricated at a ChCl-butanediol molar ratio of 1:3 independent of water presence, and that they had better oat extraction performance with 90 min extraction at 80 degrees C. Under the optimal conditions, we further assessed the impact of butanediol isomers and water addition on the structure characteristics and functionalities of extracted oat protein. The results suggested that oat protein extracted by ChCl-1,4-butanediol/water binary mixture had highest protein content, solubility, foaming capacity and stability. Our pilot findings provide crucial support to our hypothesis that the isomer of hydrogen bond donor is critically involved in the properties of oat protein the DES and the binary mixtures extracted, which pave the way for the future application of DES in protein extraction.

Recent advances in artificial enzyme cascades for the production of value-added chemicals

Enzyme cascades are efficient tools to perform multi-step synthesis in one-pot in a green and sustainable manner, enabling non-natural synthesis of valuable chemicals from easily available substrates by artificially combining two or more enzymes. Bioproduction of many high-value chemicals such as chiral and highly functionalised molecules have been achieved by developing new enzyme cascades. This review summarizes recent advances on engineering and application of enzyme cascades to produce high-value chemicals (alcohols, aldehydes, ketones, amines, carboxylic acids, etc) from simple starting materials. While 2-step enzyme cascades are developed for versatile enantioselective synthesis, multi-step enzyme cascades are engineered to functionalise basic chemicals, such as styrenes, cyclic alkanes, and aromatic compounds. New cascade reactions have also been developed for producing valuable chemicals from bio-based substrates, such as L-phenylalanine, and renewable feedstocks such as glucose and glycerol. The challenges in current process and future outlooks in the development of enzyme cascades are also addressed.
