Effect of Base/Nucleophile Treatment on Interlayer Ion Intercalation, Surface Terminations, and Osmotic Swelling of Ti₃C₂T_z MXene Multilayers was written by Natu, Varun;Pai, Rahul;Wilson, Olivia;Gadasu, Edward;Badr, Hussein;Karmakar, Avishek;Magenau, Andrew J. D.;Kalra, Vibha;Barsoum, Michel W.. And the article was included in Chemistry of Materials in 2022.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

The first MXene discovered, Ti₃C₂T_z, was synthesized by etching aluminum, Al, from the nanolaminated MAX phase, Ti₃AlC₂, using hydrofluoric acid, HF. To delaminate the resulting MXene multilayers, MLs, it was necessary to increase the interlayer spacing, by first treating them with relatively large organic cations such as tetrabutylammonium hydroxide, TBAOH, DMSO, DMSO, etc. When etched with a combination of LiF and HCl on the other hand, the Li cations spontaneously intercalated and no extra delamination step was needed. Herein, we attempt to understand why some mols. intercalate into the HF-etched MXene, while others do not. We find that treating HF-etched Ti₃C₂T_z MLs with a base, like NaOH, renders them ion exchangeable. This base treatment was found to reduce the -F terminations on the MXene surfaces, which most likely weakens the interlayer hydrogen bonding and therefore allows for ion exchange and concomitant hydration. We exploit this nucleophilic dehalogenation to functionalize the Ti₃C₂T_z surfaces using several different nucleophiles like sodium stearate, lithium ethoxide, and diisopropyl xanthogen polysulfide. We also demonstrate the effect of interlayer ions and other functional termination on the electrochem. performance of Ti₃C₂T_z in sodium ion and lithium sulfur batteries. Finally, we find that the interlayer spacing between MXene sheets derived using LiF + HCl increases dramatically when exposed to low-concentration salt solutions; this was attributed to osmotic swelling. This phenomenon was earlier observed in clays but was detected for the first time in the case of MXenes. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Category: chlorides-buliding-blocks).

Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Category: chlorides-buliding-blocks

Recovery of Cobalt, Nickel and Copper Compounds from UHT Processed Spent Lithium-ion Batteries by Hydrometallurgical Process was written by Tran, Thanh Tuan;Moon, Hyun Seung;Lee, Man Seung. And the article was included in Mineral Processing and Extractive Metallurgy Review in 2022.HPLC of Formula: 5137-55-3 The following contents are mentioned in the article:

Lithium-ion batteries (LIBs) are employed in various electronic devices and industries. The recovery of valuable metals from spent LIBs has attracted much interest due to potential environmental issues and economic values. Metallic alloys can be obtained from the UHT process of spent LIBs. In this study, a hydrometallurgical process was developed for the recovery of metal compounds from synthetic metallic alloys containing Co, Ni, and Cu. This process consisted of leaching, solvent extraction, stripping and precipitation First, the metallic mixtures were completely leached by the mixture of 2.0 moL·L^-1 HCl and 10%(volume/volume) H₂O₂ solutions at 60°C. Metal ions in the leachate were sequentially separated by solvent extraction with 0.7 moL·L^-1 Cyanex301 and 1.0 moL·L^-1 Aliquat 336 for Cu(II) and 1.0 moL·L^-1 ALi-SCN for Co(II), whereas Ni(II) was remained in the final raffinate. The compounds of Cu(II) and Co(II) were recovered from the resp. loaded organics by precipitation stripping method, while Ni(II) compounds were recovered by precipitation from the final raffinate without changing its acidity. Mass balance of the whole process indicated that the recovery percentage of metal compounds such as CuC₂O₄, CoCO₃, and NiC₂O₄ · 2 H2O was 98.6, 99.4, 99.8% from the leaching solution and the purity of the compounds was higher than 99.9%. A process was proposed for the recovery of pure metal compounds from spent LIBs. The advantages of this process are the possibility that metal compounds with high purity can effectively be synthesized and the aqueous raffinates and the stripped organic solutions after each step can be recycled. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3HPLC of Formula: 5137-55-3).

N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light.

Excellent performance of aromatic polyguanamines induced by multiple hydrogen bondable tetraazacalix[2]arene[2]-triazine ring in their main chain was written by Sasaki, H.;Kotaki, T.;Fujimori, A.;Tsukamoto, T.;Suzuki, E.;Oishi, Y.;Shibasaki, Y.. And the article was included in RSC Advances in 2020.HPLC of Formula: 2272-40-4 The following contents are mentioned in the article:

A series of poly(guanamine) (c-PG)s containing tetraazacalix[2]arene[2]-triazine (mPDA₂CyC₂) were successfully prepared by solution polycondensation of mPDA₂CyC₂ with various aromatic diamines in an aprotic organic solvent with a lithium chloride additive (5 weight%) at 150°C for 6 h. The number-average mol. weights (Mn)s of these c-PG polymers reached up to 31 500, with a relatively broad mol. weight distribution (Mw/Mn) of 5.3. They showed good solubility in aprotic organic solvents, such as N-methylpyrrolidone and N,N-dimethylacetamide at a concentration of 2 mg mL^-1. The glass transition temperatures (Tg) of the c-PG polymers were in the range 359°C-392°C, approx. 160°C higher than those of counterpart polymers (i.e., with no aza-calixarene-based PG (l-PG)). The coefficients of thermal expansion (CTEs) of the c-PG polymers were 29.7-48.1 ppm K^-1 (at 100°C-150°C), much lower than those of l-PG samples, i.e., 59.1-85.1 ppm K^-1. Transparent and almost colorless c-PG films were successfully prepared by a solution casting method, showing maximum tensile strength (σS), modulus (Eγ), and elongation at break (Eb) values of 151 MPa, 6.3 GPa, and 4.4%, resp., for the c-PG polymer from mPDA₂CyC₂ and 4,4′-oxydianiline monomers. The corresponding l-PG film exhibited σS, Eγ, and Eb values of just 76 MPa, 5.4 GPa, and 1.6%, resp. These outstanding thermal and mech. properties of the c-PG polymers can be attributed to their multiple hydrogen bonding interaction between mPDA₂CyC₂ residues in the polymer backbone. This interaction was identified by IR spectroscopy measurements at the broad absorption band around 3000-3400 cm^-1. This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4HPLC of Formula: 2272-40-4).

Design, synthesis, biological evaluation, and molecular docking study on triazine based derivatives as anti-inflammatory agents was written by Asadi, Parvin;Alvani, Mohsen;Hajhashemi, Valiollah;Rostami, Mahboubeh;Khodarahmi, Ghadamali. And the article was included in Journal of Molecular Structure in 2021.Reference of 2272-40-4 The following contents are mentioned in the article:

In an attempt to develop new anti-inflammatory agents, design, synthesis, pharmacol. activities, and docking study of two groups of triazine-based derivatives were reported. Nine compounds I and II [R′ = H, Me, CN, Br; R¹ = R² = H, Cl, methylamino, ethylamino] consisting of triazine, vanillin, and phenylpyrazole were synthesized through the pharmacophore hybridization method. After confirmation of the structure of the synthesized compounds using spectroscopic methods (FT-IR, and NMR spectral data), their anti-inflammatory activity was evaluated using carrageenan-induced paw edema model in male Wistar rats (200-220 g) administered i.p. at doses of 100 and 200 mg/kg. A group of rats received indomethacin (10 mg/kg) as the standard drug. Among compounds II, only compounds II [R¹ = R² = methylamino, ethylamino] showed a significant anti-inflammatory effect (p < 0.01). Also compound II [ R¹ = Cl, R² = methylamino] at a dose of (200 mg/kg) and compounds II at both doses showed significant anti-inflammatory activity and this effect for compound II [R¹ = Cl, R² = methylamino] (200 mg/kg) and both doses of compounds II [ R¹ = Cl, R² = ethylamino; R¹ = R² = H] was comparable with indomethacin. While indomethacin reduced paw edema by 90%, 10b as the most potent tested compound reduced edema by 93%. The synthesized compounds were docked into the binding sites of both cyclooxygenase-1- and 2- isoenzymes (COX-1 and COX-2) to explore their binding mode and possible interactions of these ligands. This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4Reference of 2272-40-4).

4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Reference of 2272-40-4

This study investigates the recovery of Zn(II) and Cr(III) from aqueous solutions based on solvent extraction with trioctylmethylammonium chloride [TOMA⁺][Cl-], commercialy named Aliquat 336. Single metal solutions and binary mixtures of both metals were considered. The effect of relevant operating conditions such as pH, contact time, initial concentration, O/A phase volumetric ratio, and temperature were evaluated. Addnl., loading capacity and stripping studies were performed. Results showed that [TOMA⁺][Cl^–] is an effective extracting agent for Zn(II), reaching maximum removal capacity at pH 1.8 and demonstrating fast extraction kinetics. Extraction efficiencies above 99% were achieved at 0.5, 0.75, and 1.00 O/A volumetric phase ratios for 0.1 g/L initial Zn(II) concentration At 1 g/L and 10 g/L concentration, for the same O/A ratios, approx. 88% of the initial Zn(II) was extracted In contrast, it was found that negligible amounts of Cr(III) were transferred to the [TOMA⁺][Cl^–] phase at the 1-5 pH range. Selectivity studies showed that Zn(II) removal is boosted in the presence of Cr(III), although no Cr(III) is extracted [TOMA⁺][Cl^–] exhibited a high Zn(II) storage capacity, since after 25 loading cycles with 1 g/L, the loading capacity reached approx. 13.5 g/L, and after five loading cycles with 5 g/L, the capacity reached 19.4 g/L. Stripping tests revealed that NaOH is an efficient agent for the removal of Zn(II) from the ionic liquids, reaching 98.5% removal after two cycles, whereas HNO₃ is not a suitable agent, reaching less than 40% removal after three cycles. [TOMA⁺][Cl^–] revealed high potential for separating Zn(II) from Cr(III).

The beneficial use of sewage sludge for valorization of carbon and nutrients is of increasing interest while micropollutants in sludge are of concern to the environment and human health. This study investigates the hydrothermal liquefaction (HTL) of sewage sludge in a continuous flow pilot scale reactor at conditions expected to reflect future industrial installations. The processing is evaluated in terms of energy efficiency, bio-crude yields and quality. The raw sludge and post-HTL process water and solid residues were analyzed extensively for micropollutants via HPLC-MS/MS for target pharmaceuticals including antibiotics, blood pressure medicine, antidepressants, analgesics, x-ray contrast media, angiotensin II receptor blockers, immunosuppressant drugs and biocides including triazines, triazoles, carbamates, a carboxamide, an organophosphate and a cationic surfactant. The results show that a pos. energy return on investment was achieved for all three HTL processing temperatures of 300, 325 and 350°C with the most beneficial temperature identified as 325°C. The anal. of the HTL byproducts, process water and solids, indicates that HTL is indeed a suitable technol. for the destruction of micropollutants. However, due to the large matrix effect of the HTL process water it can only be stated with certainty that 9 out of 30 pharmaceuticals and 5 out of 7 biocides products were destroyed successfully (over 98% removal). One compound, the antidepressant citalopram, was shown to be moderately recalcitrant at 300°C with 87% removal and was only destroyed at temperatures≥325°C (>99% removal). Overall, the results suggest that HTL is a suitable technol. for energy efficient and value added sewage sludge treatment enabling destruction of micropollutants.

Fabrication of soft-etched nanoporous polyimide membranes for ionic conduction and discrimination was written by Froehlich, Kristina;Nasir, Saima;Ali, Mubarak;Ramirez, Patricio;Cervera, Javier;Mafe, Salvador;Ensinger, Wolfgang. And the article was included in Journal of Membrane Science in 2021.Computed Properties of C4H12ClN The following contents are mentioned in the article:

Ionic selectivity in nanopores is usually based either on steric or charge exclusion mechanisms. By simultaneously incorporating both mechanisms into a functionalized membrane, an improved control over selectivity can be achieved. We describe the fabrication and exptl. characterization of alkali metal cation-selective nanopores in heavy ion-tracked polyimide (PI) membranes using the soft-etching (SE) technique. The latent ion tracks in the PI membrane are selectively dissolved by an organic solvent to form tiny pores without affecting the bulk material. The ionic transport properties of SE-PI membranes are characterized using different electrolyte solutions containing alkali metals, divalent metals, and organic cations under sym. and asym. electrolyte conditions. Under sym. conditions, the pores exhibit ohmic behavior when exposed to alkali metal chlorides and ammonium chloride solutions while divalent cations cannot pass through the pores as evidenced from the current-voltage curves. For the case of asym. electrolyte conditions, current rectification suggests pore blockage from the side of membrane exposed to divalent cations and tetraalkylammonium (TAA) cations. The exptl. data show that the SE-PI membranes efficiently discriminate alkali cations from divalent metal cations and ammonium cation from TAA cations. The ionic conduction of the membranes is also sensitive to the mole fraction of Ca2+ in multi-ionic solutions The ionic transport experiments further confirm that the nanopores allow significant alkali cation fluxes while rejecting divalent cations. Based on the good stability and high selectivity, the solvent treated PI membranes constitute remarkable candidates to be employed in applications concerning a wide range of electrolyte solutions This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Computed Properties of C4H12ClN).

Selective separation of cadmium(II), copper(II) and nickel(II) ions from electroplating wastewater using dual flat sheet supported liquid membrane was written by Lee, Lai Yee;Morad, Norhashimah;Ismail, Norli;Rafatullah, Mohd. And the article was included in Desalination and Water Treatment in 2021.Formula: C25H54ClN The following contents are mentioned in the article:

A dual flat sheet supported liquid membrane (DFSSLM) system was developed based on concurrent extraction, selective separation, and recovery of three metal ions from a mixture in a single process. DFSSLM was made up of a combination of two membranes and three compartments (feed, intermediate and strip) to selectively recover not just one but three types of metal ions at the end of the system. This research aims to study the efficiency of DFSSLM in the selective extraction of cadmium(II) and copper(II) over nickel(II) ions from an aqueous mixture and electroplating waste-water. The first membrane was impregnated with 100 mM di-(2-ethylhexyl)phosphoric acid and 50 mM tri-Bu phosphate in kerosene, whereas the second membrane was impregnated with 99.64 mM trioctylmethylammonium chloride and 50 mM tri-Bu phosphate in toluene. After continuous stirring (500 rpm) in all compartments for 48 h, 98.79% of nickel(II) was recovered from the synthetic mixture in feed, 91.32% of copper(II) in intermediate, and 91.04% of cadmium(II) in strip compartment. The flux changes and kinetic studies showed cadmium(II) was preferentially transported over copper(II). The membranes (polymer and extractants) were characterized by Fourier transform IR spectroscopy and SEM with an energy-dispersive X-ray. In comparison with the treatment of real electroplating effluent, high output/input ratios were obtained for recovered cadmium(II), copper(II) and nickel(II). Most of the other heavy metals were eliminated together with the recovery of 89.09% of cadmium(II) in the strip, 90.87% of copper(II) in intermediate, and 97.61% of nickel(II) in the feed.

The development of effective disinfection strategies, including the search for new active biocides, is a priority research for the food industry. Glycolic acid (GA) and glyoxal (GO) are two glycolysis byproducts approved as biocides for surface disinfection, whose antimicrobial action remains to be understood. This study focused on the understanding of the antimicrobial activity of GA and GO against two foodborne pathogens, Bacillus cereus and Pseudomonas fluorescens. Benzalkonium chloride (BAC) and peracetic acid (PAA) were used as reference biocides for comparison. The influence of biocide concentration and exposure time on the antimicrobial activity of the selected biocides was evaluated based on the European Standard EN 1276. The mode of action of each biocide was characterized based on their effects on the cell envelope and cell replication. According to the Chick-Watson model, all biocides interacted chem. with cell targets of both bacteria, except GO that only stablished physicochem. interactions with P. fluorescens. The survival curves revealed that high concentrations of biocide induced readily effects on cell culturability. The susceptibility profile of P. fluorescens was constant over time. In general, B. cereus increased tolerance to BAC and became more susceptible to cumulative damages of GA. Overall, this study demonstrates that the biocidal activity was species-, dose- and time-dependent. GA, similarly to BAC, was a membrane-active and oxidant agent. GO had no effect on the bacterial surface as well as PAA. GO was mainly categorized as a cell replication inhibitor. For the first time, the antimicrobial activity of GA and GO were characterized revealing their potential for rational combination with other biocides commonly used in the food industry.
