In this work, we report a family of co-halogenated two-dimensional hybrid perovskites (2DHPs) based on phenethylammonium lead halogen ((PEA)(2)Pb(Cl/Br)(4)) in which the organic cation-site (PEA) is substituted with halogen at the para-site, namely the formation of 4-halophenethylamine (X-p-PEA) (X = Cl, Br; p: para-site). The organic cations are regulated by introducing halogen ions at the para-site of the benzene ring to promote the structural distortion of the lead halide octahedral inorganic layer. Furthermore, (X-p-PEA) causes a shift in the energy band distribution of 2DHPs. In this case, the photoluminescence competition of free excitons (FEs) and self-trapped excitons (STEs) changes the microscopic relaxation process of excitons. In addition, we found that (Br-p-PEA) can increase the photoluminescence quantum yield (PLQY). At the same time, we regulate the halogen-site of perovskites from lead-chloride perovskites (LCPs) to lead bromine perovskites (LBPs), achieving emission from white light to blue light. Therefore, the co-halogenation regulation strategy of organic cation-site and halogen-site can effectively regulate the photoluminescence wavelength and improve the PLQY. This is of great significance for the development of perovskite materials with specific optoelectronic applications. (C) 2020 Elsevier Inc. All rights reserved.

This study aimed to examine the effects of ethanol-soluble components (Es) in soybean meal (SBM) on gut content transit, bile acid (BA) and pancreatic digestive enzyme secretions, nutrient apparent digestibility coefficients (ADC), liver and intestinal morphologies, and growth performance of pompano (Trachinotus blochii). The SBM was extracted with aqueous ethanol, then the supernatant and residue were separated and dried to produce ethanol-extracted SBM (ESBM) and the Es. Four experimental diets were formulated with fish meal (FM), ESBM and SBM as main dietary protein sources. The diets were denoted as follows: FMD (FM diet), SBMD (SBM diet), ESBMD (ESBM diet) and ESBM + EsD (ESBM plus Es diet). Thirty-five fingerling pompano with an initial body weight (BW) of 18.3 g were allocated to each of 12 polyvinyl chloride tanks (1000-L holding capacity), resulting in triplicate tanks per dietary treatment. For 10 weeks, the fish were hand-fed the experimental diets to apparent satiation twice daily. The results showed that the final BW, weight gain and specific growth rate were significantly lower, while the feed conversion ratio was higher in the SBMD and ESBM + EsD groups than in the ESBMD and FMD groups (p < 0.05). Fish fed SBMD and ESBM + EsD showed accelerated gastric transit, slowed intestinal mobility, and lowered secretions of BAs and pancreatic digestive enzymes as compared to those fed ESBMD and FMD. Morphological abnormalities in mucosal folds of the posterior intestine, but not the liver, were clearly observed in the SBMD and ESBM + EsD groups. These results indicated that the Es in SBM inhibited the digestive system, leading to decreased nutrient digestibility and growth performance in pompano. The findings of the present study suggested that removal of the Es would effectively improve the nutritional quality of SBM and enhance growth performance of pompano fed a SBM-based diet.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 50-30-6, Name is 2,6-Dichlorobenzoic acid, SMILES is O=C(O)C1=C(Cl)C=CC=C1Cl, in an article , author is Sun, Zhen, once mentioned of 50-30-6, Category: chlorides-buliding-blocks.

As a new type of cement-matrix composite material, coral aggregate concrete exhibits excellent properties, such as local material availability and enhanced efficiency, while being cost-effective. Coral aggregate concrete can be viable for construction on islands and reefs. Reinforced concrete structures generally exhibit low durability in marine environments, owing to long-term corrosion by chloride salts. Therefore, resistance to chloride ion attacks plays a significant role in improving the durability of concrete structures. As a non-destructive testing technique, resistivity is used for characterising the resistance of concrete to chloride ion penetration. In this study, the resistivity of coral aggregate concrete is measured using an improved alternating-current test method, and the improved method overcomes the limitations that is prone to polarization reaction and heating of the solution under exposure to voltage for an extended period. Porosity was used to analyze the reasons for the different resistivity values of coral concrete from micro-aspects. The resistivity model at 365 days was established considering the effects of temperature, humidity, admixture, and water-binder ratio on coral aggregate concrete. The hydration characteristics of cement and admixture were used to establish a time-varying model for predicting the resistivity of coral aggregate concrete. (C) 2020 Published by Elsevier Ltd.

Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition, 50-30-6, Name is 2,6-Dichlorobenzoic acid, SMILES is O=C(O)C1=C(Cl)C=CC=C1Cl, in an article , author is Liu, Yun, once mentioned of 50-30-6, Name: 2,6-Dichlorobenzoic acid.

Persistent anion binding in a wide range of solution environments is a key challenge that continues to motivate and demand new strategies in synthetic receptor design. Though strong binding in low-polarity solvents has become routine, our ability to maintain high affinities in high-polarity solvents has not yet reached the standard set by nature. Anions are bound and transported regularly in aqueous environments by proteins that use secondary and tertiary structure to isolate anion binding sites from water. Inspired by this principle of solvent exclusion, we created a sequence-defined foldameric capsule whose global minimum conformation displays a helical folded state and is preorganized for 1:1 anion complexation. The high stability of the folded geometry and its ability to exclude solvent were supported by solid-state and solution phase studies. This capsule then withstood a 4-fold increase in solvent dielectric constant (epsilon(r)) from dichloromethane (9) to acetonitrile (36) while maintaining a high and solvent-independent affinity of 10(5) M-1; Delta G similar to 28 kJ mol(-1). This behavior is unusual. More typical of solvent-dependent behavior, Cl- affinities were seen to plummet in control compounds, such as aryl-triazole macrocycles and pentads, with their solvent-exposed binding cavities susceptible to dielectric screening. Finally, dimethyl sulfoxide denatures the foldamer by putative solvent binding, which then lowers the foldamer’s Cl- affinity to normal levels. The design of this capsule demonstrates a new prototype for the development of potent receptors that can operate in polar solvents and has the potential to help manage hydrophilic anions present in the hydrosphere and biosphere.

Calcium-silicate-hydrate seeds as an accelerator for saving energy in cold weather concreting

Cold weather concreting is well-known for its high energy consumption and carbon emissions because it needs to take various measurements to prevent the frost damage of concrete. Effectively promoting the strength of concrete developed rapidly in cold weather is a crucial way to solve this problem. In this study, the chloride-free and green calcium-silicate-hydrate (C-S-H) seeds were used to modify the performance of Portland cement (PC) at the negative temperature. The results showed that the strength of PC adjusted by C-S-H seeds developed rapidly at negative temperature (-5 degrees C) within 28 d after several hours pre-curing; its strength value at 28 d (74.2 MPa) was comparable with that of PC cured at room temperature for 28 d (75.3 MPa). The addition of C-S-H seeds significantly accelerated the early hydration of PC during pre-curing and the subsequent hydration at negative temperature. The freezing point and the frozen water of cement paste were significantly reduced by C-S-H seeds and pre-curing, which can help to prevent the cement matrix from frost damage at -5 degrees C. This advantage was further demonstrated by the improvement of the microstructure caused by ice. The easy-operate and green method can significantly decrease energy consumption and CO2 emissions in cold weather concreting. (C) 2020 Elsevier Ltd. All rights reserved.

Dequalinium chloride use in adult Spanish women with bacterial vaginosis: an observational study

Bacterial vaginosis (BV) represents the most frequent vaginal infection in women of childbearing age. The aim of this study was to characterise episodes of BV among adult Spanish women and their management with dequalinium chloride (DQC). Data from 573 DQC-treated BV adult women was obtained on medical records and questionnaires. The study shows that 20.6% had presented vaginal infections previously. Comorbid candidosis was significantly associated to other symptoms, such as pruritus or leucorrhoea. Most patients (64.3%) indicated a moderate-strong impact of the BV episode on their sexual life. After treatment, 84.8% of patients reported no BV symptoms. Patients were given instructions to prevent relapses. Most patients (83.1%) rated DQC as ‘satisfactory’ or ‘very/extremely satisfactory’ regarding symptom relief, prevention or treatment of the episode of BV. In conclusion, this study provides a better understanding of BV episodes and the impact of the treatment with DQC in real clinical practice in Spanish patients. IMPACT STATEMENT What is already known on this subject? Bacterial vaginosis (BV) is the most commonly reported vaginal infection among women of childbearing age. Despite the availability of antibiotic medications for the treatment of BV, management of this condition remains challenging. In fact, recurrence of BV has been reported for up to 50% of cases. However, antiseptic agents are considered an effective option for BV treatment. What the results of this study add? The study provides a better understanding of the prevalent symptomatology and the impact on quality of life of women with BV. Moreover, it has been observed that antiseptic dequalinium chloride (DQC) efficiently reduces symptoms and improves quality of life of the patients during episodes of BV. What the implications are of these findings for clinical practice and/or further research? In the context of the World Health Organisation recommendations on the rational use of antibiotics, we believe that the use of DQC may be a good alternative to antibiotics as a therapy for BV.

Perspective: One-Cell and Cleavage-Stage Mouse Embryos Thrive in Hyperosmotic Oviductal Fluid Through Expression of a Glycine Neurotransmitter Transporter and a Glycine-Gated Chloride Channel: Clinical and Transgenerational Implications

The osmolality of mouse oviductal fluid ranges from about 300 mOsmol/kg in the ampulla 0-3 h post coitus (h p.c.) to more than 350 mOsmol/kg in the isthmus 34-36 h p.c. Thus, it has been surprising to find that development of one-cell and cleavage-stage mouse embryos arrests in vitro in media exceeding 300 mOsmol/kg, and they develop best in unphysiological, hypotonic media. The glycine concentration in oviductal fluid can, however, rescue development in hypertonic media, so physiological conditions in vivo and in vitro likely work together to foster embryo well-being. Glycine acts on one-cell and cleavage-stage mouse embryos through the glycine-gated chloride channel, GLRA4, and uptake via the glycine neurotransmitter transporter, GLYT1. Since these processes lead to further signaling in neurons, the presence and function of such signaling in preimplantation embryos also should be investigated. The more we know about the interactions of physiological processes and conditions in vivo, the better we would be able to reproduce them in vitro. Such improvements in assisted reproductive technology (ART) could improve patient outcomes for IVF and potentially help prevent unwanted developmental abnormalities in early embryos, which might include undesirable epigenetic DNA and histone modifications. These epigenetic modifications may lead to transgenerational adult disorders such as metabolic syndrome and related conditions.

Investigation on the Corrosion of the Elbows in the Flue Gas Cooler of a 600 MW Coal-Fired Power Plant

Sulfuric acid condensation has long been considered as the major cause of the corrosion issues at the cold-end of coal-fired boilers. However, in a flue gas cooler, where flue gas is cooled to around 90 degrees C for heat recovery, the influence of chlorides might be underestimated. In this article, some elbows of the heat transfer tubes in the flue gas cooler of a coal-fired power plant were found to be badly corroded, after a 5-year operation. The corroded elbows, coupled with the corrosion products and deposits on the tube wall, were sampled and analyzed by scanning electron microscopy, energy dispersive spectrometry, X-ray diffraction, X-ray fluorescence spectroscopy, and ion chromatography. The results indicated that chlorides, unexpectedly, formed in flue gas before the dew point for hydrochloric acid was met. The corrosion layer on the steel surface was mainly composed of Fe2O3, Fe3O4, and FeO(OH), while showing an oxidation gradient in depth. The sulfates in the corrosion products were rather limited. Instead, Cl- from the deposits gradually accumulated deep inside the corrosion layer, resulting in a considerable generation of Cl-containing compounds. The enrichment of Cl induced cracking and spalling of the corrosion products, and greatly accelerated the failure of the tube wall.

Light-accelerating oxidase-mimicking activity of black phosphorus quantum dots for colorimetric detection of acetylcholinesterase activity and inhibitor screening

A feasible and sensitive colorimetric platform was established for the assay of acetylcholinesterase (AChE) activity and evaluation of its inhibitor screening, based upon the light-accelerating oxidase-mimicking activity of black phosphorus quantum dots (BP QDs). The BP QDs were synthesized through a thermal exfoliation method and characterized using various techniques. The BP QDs exhibit oxidase-mimicking catalytic activity on dissolved oxygen-mediating oxidation of 3,3 ‘,5,5 ‘-tetramethylbenzidine, a typical substrate of oxidase. This results in a transformation of 3,3 ‘,5,5 ‘-tetramethylbenzidine into its blue oxidized product, which has a visible absorption peak at 652 nm. The exposure of 365 nm light irradiation significantly accelerates the oxidase-mimicking activity of the BP QDs and speeds up the reaction efficiency. AChE can specifically catalyze the decomposition of its substrate acetylthiocholine chloride to thiocholine. Thiocholine has reducing capacity and can thus reduce the oxidase-mimicking activity of the BP QDs. As a result, the oxidation of 3,3 ‘,5,5 ‘-tetramethylbenzidine is hindered and the blue solution becomes paler. This gives a linear response for AChE ranging from 0.5 to 10.0 mU mL(-1) and a detection limit of 0.17 mU mL(-1). The assay was successfully applied to evaluate inhibitor screening with neostigmine as the model.

Lithium extraction from synthetic brine with high Mg2+/Li+ ratio using the polymer inclusion membrane

Lithium extraction from brines with the high Mg2+/Li+ ratio is crucial for sustainable lithium resource and environmental protection. This study incorporated the classic tributylphosphate (TBP)/FeCl3 system into the polyvinyl chloride (PVC) based polymer inclusion membrane (PIM) to extract Li+ from the solution which is rich of Mg2+ (The initial Mg2+/Li+ molar ratio is 15). The morphology and composition of PIMs were characterized systematically, and the content of TBP/FeCl3 carrier in the PIM was optimized. Compared to liquid-liquid extraction, the extraction ratio of Li+ for PIM extraction increases by 20% and the separation factor of Li+ over Mg2+ increases by 5%. Besides, the loss ratio of Fe3+ after one loop of liquid-liquid extraction is 17.79%, which is close to that of PIM extraction after three loops (18.30%), demonstrating that the PIM showed a good stability. Furthermore, the separation factor of Li+ over Mg2+ for the PIM with 50 wt% TBP/FeCl3 is as high as 176 and the initial flux for Li+ is 8.12 x 10(-4) mol m(-2) h(-1). This study displays a TBP/FeCl3 based PIM with high selectivity for Li+, providing a possible membrane technology for lithium extraction from brines.
