Nickel- and Palladium-Catalyzed Cross-Coupling Reactions of Organostibines with Organoboronic Acids

A strategy for the formation of antimony-carbon bond was developed by nickel-catalyzed cross-coupling of halostibines. This method has been applied to the synthesis of various triaryl- and diarylalkylstibines from the corresponding cyclic and acyclic halostibines. This protocol showed a wide substrate scope (72 examples) and was compatible to a wide range of functional groups such as aldehyde, ketone, alkene, alkyne, haloarenes (F, Cl, Br, I), and heteroarenes. A successful synthesis of arylated stibine 3 a in a scale of 34.77 g demonstrates high synthetic potential of this transformation. The formed stibines (R3Sb) were then used for the palladium-catalyzed carbon-carbon bond forming reaction with aryl boronic acids [R-B(OH)(2)], giving biaryls with high selectivity, even the structures of two organomoieties (R and R ‘) are very similar. Plausible catalytic pathways were proposed based on control experiments.

The influence of activator type and quantity on the transport properties of class F fly ash geopolymer

It is known that transport properties of porous materials were important in terms of its durability aspect. In this paper, the effect of activator type, Na amount on the transport properties of geopolymer mortar made with class F fly ash were explored. Two different class F fly ash were employed in producing geopolymer that activated alkaline solutions. As alkali activator, sodium hydroxide solution, and combination of sodium silicate with sodium hydroxide were used. Activator contained 6%, 9%, 12% and 15% of fly ash weight as Na amount. Heat curing regimes were imposed to specimens at 100 degrees C temperature for 24 h duration. Tests were carried out on the geopolymer samples including water absorption, volume of permeable voids, sorptivity, depth of penetration of water under pressure, chloride ion penetration and accelerated corrosion. It is found that the transport properties of geopolymer samples are improved by increasing the Na amounts of mortar mixtures from 6% to 15%. In general, better results were obtained with 15% Na ratio. The mortars produced with only sodium hydroxide have shown better transport properties than mortars made with combination of sodium hydroxide-sodium silicate mixture. (C) 2020 Elsevier Ltd.

Ligand dependent magnetism of the J(eff)=3/2 Mott insulator Cs2MX6 (M = Ta, Nb, X = Br, Cl)

Magnetic and structural properties of double perovskite type bromides Cs2MBr6 (M = Ta, Nb), where Ta4+ (5d(1)) and Nb4+ (4d(1)) ions form the face centered cubic lattice, are investigated and compared with chlorides Cs2MCl6. Cs2TaBr6 exhibits the effective magnetic moment of 0.24 mu(B), which is much smaller than the spin only value of a d(1) ion, 1.73 mu(B), and comparable to 0.25 mu(B) in Cs2TaCl6. On the other hand, the effective magnetic moment of Cs2NbBr6 is 0.7 mu(B) and is substantially smaller than 1.0 mu(B) in Cs2NbCl6. On cooling, successive structural and magnetic phase transitions accompanying the release of electronic entropy approximately Rln 4 in total as expected for the J(eff) = 3/2 state are observed. The type of the ligand changes the temperature dependence of magnetic susceptibility at low temperature as well as its magnitude. The role of the ligands on the magnetism of J(eff) = 3/2 Mott insulators are discussed in the light of metal-ligand hybridization and the electron-lattice coupling.

Action of chloride ions as a habit modifier in the hydrothermal crystal growth of rutile TiO2 nanorod from SnO2 seed crystal

The mechanism of hydrothermal heteroepitaxial growth of rutile TiO2 nanorods from SnO2 seed nanocrystals under acidic conditions was studied. On the basis of the experimental and density functional theory (DFT) simulation results, we have presented a reaction mechanism that chloride ions are preferentially adsorbed on the oxygen-defect sites on the (110) plane of TiO2 to suppress the growth, and consequently, TiO2 grows in the [001] direction to yield the nanorod with the (1 1 0)-faceted side walls. Importantly, the DFT simulations indicated that easy defect formation on the (110) facet is a key to the preferential adsorption of chloride ions.

Removal of selected emerging micropollutants from wastewater treatment plant effluent by advanced non-oxidative treatment – A lab-scale case study from Serbia

The presence of 48 emerging micropollutants was tested in influent and effluent from primary and secondary treatment at a municipal wastewater treatment plant (WWTP) in Serbia. Sixteen emerging micropollutants (active pharmaceutical ingredients, bisphenols, parabens and UV filters) had concentrations >LOQ (max. conc. 33.4 mu g/L). The removal efficiency of primary treatment ranged from 2.0% – 96.0%. In the case of secondary treatment, except for ketoprofen (61.0%), diclofenac (62.6%) and carbamazepine (- 20.0%), all other measured micropollutants had removal efficiency above 77.0%. Advanced non-oxidative lab-scale treatments were investigated. Powdered activated carbon (PAC) adsorption achieved removal efficiencies in the range 52.4-99.9%, novel coagulation with natural coagulant isolated from beans achieved removal efficiencies in range 3.2-99.9%, conventional coagulation with ferric chloride 3.12-96.4%, combined adsorption/coagulation 2.69-99.9% and combined PAC/ultrafiltration (PAC/UF) 60-99.9%. For most of the micropollutants, their removal efficiencies were similar to that reported in the literature. Novel natural coagulant showed significant potential compared to the conventional coagulant during a short episode of sub-optimal WWTP operation. When natural coagulant was applied as a part of an adsorption/coagulation hybrid process, there was no negative effect on PAC adsorption, while for conventional coagulant that was not always the case. Also, a structure property relationship (SPR) study revealed correlations between the removal efficiency of the majority of treatments applied and total polar surface area (TPSA) of the micropollutants.

Effect of pulsed vacuum and laser microperforations on the potential acceleration of chicken meat marination

Chicken meat marination has become a fundamental process in the poultry industry since it provides a product with better sensory attributes. The objective of this study was to examine the effect of CO2 laser microperforation coupled with vacuum impregnation treatment on the marination processing time of chicken breasts and to mathematically analyze the marinade diffusion process using Fick’s second law and an anomalous diffusion model. Cylindrical cuts of unmarinated chicken meat were CO2-laser microperforated with pores of 228 mu m and marinated under vacuum pressure (15 kPa) with NaCl (3% wt/wt) and sodium tripolyphosphate (1% wt/wt) during 60 hr at 6 degrees C. The chicken:brine ratio was 1:11 wt/wt. Mass gain, moisture content, and salt concentration were determined over time; furthermore, effective diffusion coefficient (D-eff) was obtained using Fick’s second law and anomalous diffusion models. Marinade diffusion into chicken cuts was favored by microperforation combined with vacuum pulses, reduction processing time in 34%. The D-eff ranged between 1.46 x 10(-10) and 2.08 x 10(-10)m(2)/s for Fick’s second law and between 2.27 x 10(-10) and 4.23 x 10(-10)m(2)/s(alpha) for anomalous diffusion model, with alpha-values close to 1. In conclusion, the results showed no significant difference between the models, which was attributed to the homogeneity of the chicken tissue. Practical Applications Chicken meat marination has become a fundamental process in the poultry industry since it provides a product with better sensory attributes and shelf life than unmarinated chicken meat. Nevertheless, marination is a process that requires a long processing time to obtain a specified salt content in the meat. In this sense, laser microperforation of the meat is a treatment that when coupled with vacuum impregnation, can accelerate the marinating process of poultry meat. When simultaneously applying both technologies, the processing time was reduced by 6 hr compared with the control (almost 34%), which will allow a significant increase in plant productivity.

Synthesis of a novel lignin-based epoxy resin curing agent and study of cure kinetics, thermal, and mechanical properties

In this contribution, first of all, the methoxy groups of organic solvent lignin (OSL) was converted to phenolic hydroxyl groups through demethylation reaction for the purpose of fabricating demethylated organic solvent lignin (DOSL). In addition, the resulting DOSL was utilized as a renewable material to synthesize a novel esterified lignin (EDOSL) by reacting with isobutyryl chloride for curing of epoxy resin. Finally, commercial liquid diglycidyl ether of bisphenol A was cured by EDOSL in the presence of 4-dimethylaminopyridine (DMAP) used as a catalyst based on dual-curing mechanism. Dual curing is a processing methodology based upon the alliance of two diverse and compatible polymerization reactions occurring sequentially or simultaneously. According to the FTIR spectra and H-1-NMR analyses, the demethylation of OSL, esterification of DOSL, and the curing reaction of epoxy resin with EDOSL were successfully conducted. The value of the phenolic hydrogen in the DOSL was approximately 4.89 mmol/g, which increased by 12.64% after demethylation. The thermal and mechanical performances of these cured epoxy samples were measured by DSC, DMA, TGA, and tensile testing. The epoxy system cured by 10%wt esterified lignin with 1%wt DMAP possessed the tensile strength of 71.54 +/- 7.50 MPa and the initial degradation temperature (T-5%) of 370 degrees C, which can compete fairly with commercial aromatic curing agents or other lignin-based agents studied currently for the curing of epoxy systems.

Interoceptive insular cortex participates in sensory processing of gastrointestinal malaise and associated behaviors

The insular cortex plays a central role in the perception and regulation of bodily needs and emotions. Its modular arrangement, corresponding with different sensory modalities, denotes a complex organization, and reveals it to be a hub that is able to coordinate autonomic and behavioral responses to many types of stimuli. Yet, little is known about the dynamics of its electrical activity at the neuronal level. We recorded single neurons in behaving rats from the posterior insula cortex (pIC), a subdivision considered as a primary interoceptive cortex, during gastrointestinal (GI) malaise, a state akin to the emotion of disgust in humans. We found that a large proportion of pIC neurons were modulated during the rodent compensatory behaviors of lying on belly (LOB) and Pica. Furthermore, we demonstrated that LOB was correlated with low-frequency oscillations in the field potentials and spikes at the theta (8 Hz) band, and that low-frequency electrical microstimulation of pIC elicited LOB and Pica. These findings demonstrate that pIC neurons play a critical role in GI malaise perception, and that the pIC influences the expression of behaviors that alleviate GI malaise. Our model provides an accessible approach at the single cell level to study innate emotional behaviors, currently elusive in humans.

Evaporated potassium chloride for double-sided interfacial passivation in inverted planar perovskite solar cells

Defect-induced charge carrier recombination at the interfaces between perovskite and adjacent charge transport layers restricts further improvements in the device performance of perovskite solar cells (PSCs). Defect passivation at these interfaces can reduce trap states and inhibit the induced nonradiative recombination. Herein, we report a double-sided interfacial passivation via simply evaporating potassium chloride (DIP-KCl) at both the hole transport layer (HTL)/perovskite and perovskite/electron transport layer (ETL) interfaces in inverted planar PSCs. We demonstrate that the bottom KCl layer at the HTL/perovskite interface not only reduces the interfacial defects and improves the interfacial contact, but also leads to increased perovskite crystallinity, while the top KCl layer at the perovskite/ETL interface efficiently passivates the perovskite top surface defects and facilitates electron extraction at this interface. Thus, suppressed nonradiative recombination and faster charge extraction at both interfaces close to the perovskite layer can be achieved by using our DIP-KCl strategy. As a result, inverted PSCs based on DIP-KCl present an increased efficiency from 17.1% to 19.2% and enhanced stability, retaining over 90% of their initial efficiency after aging at maximum power point tracking for 1000 h. This work provides a simple and efficient way for defect passivation to further increase the efficiency and stability of PSCs.

Fundamental Study of Palladium Recycling Using Dry Aqua Regia Considering the Recovery from Spent Auto-catalyst

In this research, a recycling process for palladium using dry aqua regia, which consists of iron(III) chloride-potassium chloride, was proposed. Palladium was dissolved in dry aqua regia, and the dissolved palladium was recovered by leaching with potassium chloride solution with added ammonium chloride and nitric acid. Palladium was almost completely dissolved in 3 h at 600 K, and the recovery ratio of dissolved palladium was up to 80%. In addition, the dissolution of palladium in coexistence with platinum and the dissolution of platinum-palladium alloy by dry aqua regia were also tested. The dissolved palladium and platinum were separated and recovered by solid-liquid separation technique using the difference in solubility of their compounds in potassium chloride and sodium chloride solutions. As a result, pure compounds of each element were recovered. This result suggested the possibility of using dry aqua regia for the separation of platinum-group metals.Graphical Abstract
