Amine-borane complex-initiated SF5Cl radical addition on alkenes and alkynes

The SF5Cl radical addition on unsaturated compounds was performed using an air-stable amine-borane complex as the radical initiator. This method showed to be complementary to the classic Et3B-mediated SF5Cl addition on alkenes and alkynes. A total of seven alkene and three alkyne derivatives were tested in the reaction, with yields ranging from 3% to 85%.

Characterization of electrode fouling during electrochemical oxidation of phenolic pollutant

Electrode fouling is a problem that commonly occurs during electro-oxidation water purification. This study focused on identifying the fouling behavior of Pt electrode associated with the formation of polymeric layer during electro-oxidation of phenol. The in situ electrochemical measurements and non-destructive observation of the electrode morphology were reported. The results demonstrated that the electrode fouling was highly dependent on thermodynamic process of electrode that was controlled by anode potential. At anode potential lower than 1.0 V vs SHE, the direct electro-oxidation caused the electrode fouling by the formation of polymeric film. The fouling layer decreased the electrochemically active surface area from 8.38 cm(2) to 1.57 cm(2), indicated by the formation of polymeric film with thickness of 2.3 mu m, increase in mass growing at a rate of 3.26 mu g/cm/min. The degree to which the anode was fouled was independent of anion in the electrolyte. In comparison, at anode potential higher than 2.7 V vs SHE, the anions (e.g., chloride) could exert a major influence to the behavior of electrode fouling. The presence of chloride was shown to mitigate the fouling of electrode significantly through preventing the formation of polymeric film by active chlorine (e.g., Cl center dot and Cl-2) produced from anodic oxidation of chloride. Since chloride is the most abundant anionic species existing in both natural and engineered water system, this study not only offers a deep insight into the mechanism of electrode fouling, but also suggests strategies for anti-fouling in the presence of chloride in electro-oxidation process.

Influence of salinity on survival, growth, hemolymph osmolality, gill sodium potassium ATPase activity, and sodium potassium chloride co-transporter expression in the redclaw crayfish Cherax quadricarinatus

The Australian redclaw crayfish Cherax quadricarinatus is a freshwater crustacean aquacultured in many countries. Redclaw crayfish are often exposed to saline waters in attempts to improve flavor, to relieve stress during transport, and to prevent or treat parasitic infestations. However, the effect of salinity on the crayfish osmoregulatory process is not well studied. In the present work, we assessed the effect of various salinities on survival, growth, and osmoregulation in redclaw crayfish. Adult crayfish were maintained at seven salinities (0, 2, 4, 6, 8, 10, and 12 ppt) for 4 weeks, and hemolymph osmolality, gill sodium potassium ATPase activity, and sodium potassium chloride cotransporter expression were assessed. In another experiment, juvenile crayfish were size sorted to similar weights and stocked at four salinities (0, 2, 4, and 6 ppt) for 8 weeks. The animals were group weighed every 2 weeks and individually weighed at the end of the eighth week. Hemolymph osmolality was constant as salinity increased from 0 to 10 ppt then a significant increase was observed at 12 ppt. Redclaw growth rate decreased with an increase in salinity from 0 to 6 ppt. Sodium potassium ATPase activity and sodium potassium chloride cotransporter expression increased with salinity increase. Although salinity might help treat ectoparasites, improve taste, and reduce transportation stress, long-term exposure increases osmoregulatory metabolic costs and affects growth and energy consumption.

Antifouling, antibacterial and non-cytotoxic transparent cellulose membrane with grafted zwitterion and quaternary ammonium copolymers

Copolymer brushes with different ratios of sulfobetaine methacrylate (SBMA) and [2-(Acryloyloxy)ethyl] trimethylammonium chloride (DAC) were grafted from transparent cellulose membrane (CM) via surface-initiated atom transfer radical polymerization (SI-ATRP) method for improving its antifouling and antibacterial performance. Surface concentrated copolymer grafting on the cellulose membranes can be obtained without significantly sacrificing the transparency and mechanical properties. The zwitterionic PSBMA chains of the copolymers can lead to an extremely hydrophilic surface with significantly reduced non-specific protein adsorption and bacterial attachment, therefore, leading to satisfying antifouling and antibacterial property. While the PDAC chains of the copolymers improved antibacterial performance against both Gram-positive and Gram-negative bacteria due to the presence of quaternary ammonium groups, the PDAC modified CM (CM-1) possessed best antibacterial performance, reaching to 95.1 % against S. aureus and 90.5 % against E. coli, respectively. More importantly, the biocompatibility of all grafted CM was retained, leading to over 100 % cell viability.

CQDs decorated oxygen vacancy-rich CeO2/BiOCl heterojunctions for promoted visible light photoactivity towards chromium (VI) reduction and rhodamine B degradation

Engineering a heterojunction with high photoactivity and better exciton separation in photocatalyst is a promising target for environmental purification. In this context, we fabricated CQDs decorated double-shell CeO2 hollow spheres(D-CeO2)/BiOCl heterojunction (D-CeO2: CQDs/BiOCl) composite by a simple method and scrutinized it photocatalytic performance toward chromium (VI) reduction and rhodamine B degradation. The resultant D-CeO2: CQDs/BiOCl composite is validated much more active under visible light irradiation with the high rhodamine B degradation rate of 0.12min(-1) which is about 3 and 255 times, meanwhile, chromium (VI) reduction rate of 0.015 min(-1) which is about 6 and 32 times higher than the neat BiOCl and D-CeO2, respectively. The interfacial domain of D-CeO2/BiOCl decorated with CQDs for efficient photoinduced charge carriers transfer and separation are the point to attractive photocatalytic performance which combines the double-shell hollow sphere morphology with highly efficient light harvesting, rich OVs for the charge carriers fast separation and accelerated charge transfer after the CQDs participating.

A novel turn-on fluorometric reporter-spacer-receptor chemosensor based on calix[4]arene scaffold for detection of cyanate anion

Herein, a novel calix[4]arene compound, which was modified by the 2-(2-aminophenyl)benzothiazole fragment with cyanate recognition function was designed based on the reporter-spacer-receptor sensing system. The construction was done via two-step reaction, and the desired sensor 4 was characterized by FT-IR, H-1-, C-13-NMR, and fluorescence spectroscopy along with HRMS data. The sensor candidate showed distinct fluorometric cyanate detection by means of reporter feature of selected benzothiazole constituent. In the presence of cyanate, the sensor gave a turn-on-type fluorescence at 482 nm with a large stokes’ shift. Furthermore, it was observed that our fluoroionophore 4 is highly selective toward cyanate over remaining anions such as sulfate, phosphate, fluoride, chloride, bromide, iodide, chlorate, and nitrate in 10% aqueous solution of DMSO. The 1:2 stoichiometric ratio of the 4-cyanate complex was given the best fit with Job’s plot based on the titration data. The association constant (K-a) of sensor 4 with cyanate is determined to be 1.64 x 10(5) M-2. The obtained limit of detection (LOD) value for cyanate anion, 312 nM, clearly revealed the remarkable sensitivity of the chemosensor 4. This supramolecular method provides a highly adaptive technique for the detection of cyanate and so cyanide ions by current international standard methods.

Evaluation of ion content, productivity and essential oil quality of garlic under saline conditions and biochar and polyamine treatments

In 2018, a pot experiment was carried out to evaluate the performance and essential oil quality of garlic under salinity and biochar and polyamine treatments. Results showed that about 18 compounds were identified in garlic bulbs essential oil, some of which only induced by the salt stress, 20 % of biochar and putrescine treatments. Diallyl trisulfide and diallyl disulfide were the major constituents of essential oil. The 1-propenyl methyl disulfide and methyl allyl trisulfide were only induced by salt stress. The butyl propenyl sulfide was only produced in biochar treated plants under salt stress. Application of putrescine stimulated the synthesis of 3-ethenyl1,2-dithiane and 2-ethenyl-1,3-dithiane under normal condition and 3,5-diethyl-1,2,4, trithiolane under saline conditions. Overall, biochar and polyamines improved growth and essence quality of garlic under salinity, which may have related to sodium (Na+) and chloride (Cl-) reduction and potassium (K+), calcium (Ca2+), and K+/Na+ enhancement.

Mechanisms of acclimation to hypersalinity in two European sea bass lineages: a focus on the kidney function

European sea bass (Dicentrarchus labrax), a major aquaculture species, is distributed along the coasts of the North-Eastern Atlantic Ocean, Mediterranean and Black Sea. D. labrax enter lagoons and estuaries where salinity fluctuates and sometimes reaches levels over 60%o, notably in Mediterranean lagoons. Keeping in mind that European sea bass are genetically subdivided in an Atlantic and a Mediterranean lineage, we compared fish from Atlantic (A) and West Mediterranean (M) populations regarding their capacity to tolerate hypersalinity with a focus on the kidney, a key organ involved in water reabsorption at high salinity. Fish were analyzed following a two-week transfer from seawater (SW, 36%o) to either seawater (SW, 36%o) or hypersaline water (HW, 55%o). Plasma osmolality was significantly increased in the MHW group compared to the other groups. Plasma sodium levels were significantly increased in hypersaline water compared to seawater in both lineages whereas plasma chloride levels showed an opposite trend. In order to estimate water filtration at the kidney level, the size of renal glomeruli was investigated and showed a decreased glomerulus perimeter and area in hypersaline water compared to seawater. NKA was highly expressed in all kidney tubules notably collecting tubules and ducts. There was an effect of salinity on renal nka alpha 1a mRNA expression with slightly lower transcript levels at 55%o compared to 36%o. Relative protein amounts and activity of NKA however were significantly higher in fish exposed to hypersalinity regardless of their origin. AQP1a immunolabeling differed between proximal tubules subtypes and only faint AQP1a was detected in subapical parts of cells lining collecting ducts. The transcript levels of renal aqp 1a were lower in the HW group than the SW group whereas the expression of other aqp paralogs (aqp 1b, aqp 8b) did not change according to the analyzed conditions. This study showed an efficient acclimation of sea bass to high salinity by increasing active ion transport at the kidney and by decreasing the size of filtering glomeruli to minimize water loss through urine. Despite Mediterranean D. labrax are supposed to more often encounter high salinities in their habitat, their high blood osmolality in hypersaline water indicates that their overall response to hypersalinity seems not improved compared to the Atlantic lineage. However, at the kidney level, the traits analyzed differ slightly between genetic lineages, potentially as a response to high blood osmolalities in MHW.

Insight into the Deep Eutectic Solvent Extraction Mechanism of Flavonoids from Natural Plant

Deep eutectic solvents (DESs) are a new class of green solvents with potential applications for the extraction of target compounds from both liquid and solid samples. However, current research in the field has focused on demonstrating the advantages in extraction efficiency in terms of more extracted material and shortened time, while the mechanism of the increased efficiency has not been systematically studied. Herein, we explored the solvent and solute interaction mechanisms with the use of three extraction methods (heating, microwave-assisted, and mechanochemical extraction) and different types of DESs. Choline chloride (ChCl) was used as the hydrogen-bond acceptor, while hydrogen-bond donors used are malonic acid, methylurea, and glycerin. Flavonoids from Flos Sophorae were extracted. H-1 nuclear magnetic resonance (NMR) spectrometry, ultraviolet-visible (UV-vis) spectrometry, scanning electron microscopy (SEM), and ultrahigh-performance liquid chromatography (UPLC) analyses were performed to investigate the interactions between the flavonoids and the plant cell walls with DESs, and chemical reactions between the DESs and flavonoids. We also systematically evaluated the influence of several key factors on the extraction efficiency, which was consistent with the experimental results. The influence of DES in the sample on qualitative and quantitative UPLC analyses was systematically studied, and conditions were optimized. This study should provide insights into the interactions of specific DESs with various target compounds and help design more efficient extraction methods.
