Solvometallurgical process for the recovery of rare-earth elements from Nd-Fe-B magnets

The protic ionic liquid pyridine hydrochloride is known to be a non-aqueous solvent for metal oxides, including rare-earth oxides. However, its application in extractive metallurgy and especially in solvent extraction has been so far limited by its miscibility with the aqueous phase. In this paper, molten pyridine hydrochloride (165 degrees C) was used to dissolve production scrap of Nd-Fe-B permanent magnets to recover the valuable metals neodymium and dysprosium. The Nd-Fe-B scrap powder completely dissolved in just 10 min with a lixiviant-to-solid ratio of 10 g g(-1). Afterwards, non-aqueous solvent extraction was performed at high temperature (165 degrees C) by using molecular extractants (PC-88A) or ionic liquids (Cyphos IL 101). The high temperature lowers the viscosity of the solvents, so that they can be used in undiluted form. Moreover, the high temperature affects the equilibrium constants and, hence, the distribution of the metals between the two phases. In the first stage, 30 vol% PC-88A in p-cymene was used to extract dysprosium(III), whereas in the second stage 100 vol% PC-88A was used to extract most of the neodymium(III). Finally, a mixture of Cyphos IL 101-p-cymene 70:30 (wt.:wt.) was shown to efficiently extract iron(II,III) from the concentrate leachate. A conceptual flowsheet was designed, which included the recycling of the pyridine hydrochloride to lower the costs and the environmental impact of the process.

Photocatalytic oxidation of tetracycline by magnetic carbon-supported TiO2 nanoparticles catalyzed peroxydisulfate: Performance, synergy and reaction mechanism studies

TiO2 decorated on ferroferric oxides coupled with activated carbon (TFOC), as a magnetic heterogeneous catalyst, was synthesized and its photocatalytic ability was assessed in coupling with UV light towards peroxydisulfate (PS) activation to degrade tetracycline (TC). Main properties of the catalyst were analyzed by using UV-visible DRS, FESEM, VSM, PL, EDS, TEM, XRD and BET techniques. A proposed reaction mechanism was suggested for activating PS and TC degradation. Both TiO2 and Fe3O4 (FO) were synthesized and dispersed successfully on the carbon surfaces in nano-sized scale. It was found that the photocatalytic activity of TiO2 was accelerated significantly after loading on the magnetic carbon. TFOC showed an excellent magnetic response in the presence of a magnet. According to PL analysis, FO nanoparticles and carbon played a critical role in the suppression of recombination of excited electrons and holes. TFOC in coupling with UV showed a best performance, compared to the other single and binary processes for TC decontamination. After 15 min reaction, the highest level of elimination, 96% TC (60 mg/L) and 72.1% TOC were obtained at optimum operational conditions: pH:5.0, TFOC: 0.3 g/L and PS:1.0 mM. A noticeable synergistic effect was found for TFOC in combination with UV and PS. Both negligible Fe leaching and high efficiency of degradation were achieved with reused times, illustrating that TFOC has an excellent durability and reusability. Based on trapping tests, the importance of involved oxidizing species during TC decontamination over TFOC/PS/UV system was in order of O-1(2) > SO4 center dot- > h(+) > O-2(center dot-) > HO center dot. Among studied anions, the highest quenching impact was observed for chloride ions. Particularly, TFOC composite showed the high catalytic activity as well excellent potential in recovery and its coupling with UV light and PS can be introduced as a promising strategy for efficient destroying TC antibiotic.

Adhesive, Self-Healing, and Antibacterial Chitosan Hydrogels with Tunable Two-Layer Structures

Hydrogels with multifunctional properties such as biocompatibility, adhesion, and self-healing and inherent antibacterial properties are of great significance in biomedical applications, especially for wound dressings and drug release. However, it remains a significant challenge to combine all of these properties in a one-component hydrogel system. Furthermore, most injectable hydrogels are mechanically weak and not self-healing, which limits their applications as wound dressings. Herein, we designed a hydrogel with a tunable two-layer structure that endows the hydrogel with adhesion, self-healing, and antibacterial properties in different layers. First, chitosan (CHI) was oxidized to aldehyde-chitosan (ACHI). The Schiff base reaction was then used to fabricate the CHI/ACHI hydrogel resulting in the first layer. For the second layer, a physical cross-linking process using phytic acid (PA) as a sequential cross-linker was achieved, resulting in a CHI/ACHI/PA hydrogel. The CHI/ACHI hydrogel exhibited good injectable, adhesion, and self-healing properties. After cross-linking with PA, the CHI/ACHI/PA hydrogel showed enhanced mechanical properties, which enabled it to act as a protective layer. Additionally, the antibacterial test and cytotoxicity tests performed on this two-layer structured CHI/ACHI hydrogel exhibited excellent inherent antibacterial activity and good biocompatibility. The biocompatible injectable hydrogel was endowed with more possibilities relying on its self-healing and antibacterial abilities. These properties endorse the CHI/ACHI two-layer hydrogel as an excellent candidate for biological applications, especially wound dressings.

Adsorption of Indigo Carmine dye onto the surface-modified adsorbent prepared from municipal waste and simulation using deep neural network

A new adsorbent was prepared from municipal wastes (a mixture of Corn Stover, Paper Waste, and Yard Waste) by cationization with 3Chloro2 Hydroxypropyl Trimethylammonium Chloride. The FTIR spectrum confirmed the quaternary ammonium group’s presence on the adsorbent surface (1450 cm-1). The maximum adsorption capacity (148 mg/g) was higher than the earlier reported values. Liu isotherm described well the adsorption process, with a high R2adj value (0.997). The pseudo-first-order equation fits well for kinetic data, and thermodynamic experiments demonstrated the endothermic nature of the adsorption. The deep neural network (DNN) is applied to simulate the adsorption process, which outperformed the classical machine learning and shallow neural network models. The DNN model predicted accurately the adsorption process with the lowest deviation from the actual values with Mean Absolute Error (MAE = 3.2), Root Mean Squared Error (RMSE = 4.89), and the highest performance accuracy of R-2 (0.96) as compared to various classical ML algorithms such as Linear Regressions (MAE = 12.53, RMSE = 18.01, R-2 = 0.42), Random Forest (MAE = 5.81, RMSE = 10.05, R-2 = 0.82), and Extra Trees (MAE = 4.35, RMSE = 8.22, R-2 = 0.88). The utilized DNN model can be used for predicting the removal efficiency of dyes for various combinations of input parameters without going through laboratory experiments.

Ionic and pH responsive thin film composite hollow fiber nanofiltration membrane for molecular separation

Ionic and pH responsive thin film composite (TFC) membrane is prepared by interfacial polymerization of lysine and trimesoyl chloride on the out surface of poly (m-phenylene isophthalamide) hollow fiber membrane. Hydrophilicity and strong negative charge of the TFC membrane are obtained by introducing a large amount of carboxylic groups in the cross-linked polyamide network, endorsing the ionic and pH response of the TFC membrane in terms of flux and rejection. The TFC membrane shows almost 100% rejection for Eriochrome black T, with a flux of 35.8 L/m(2)h (0.2 MPa) at low pH and salt concentration. However, the rejection decreases to 95.8%, and the flux increases more than three times at high pH and salt concentration due to the shift of the interaction in the polyamide network from hydrogen bonding to static-electric repulsion. The responsive TFC membrane also shows great performance in separation of dye-salt mixture and dye mixture.

The structure was determined at 110 K from 4333 reflections (3520 observed) with R = 0.041 (R-w = 0.082). The iron is pseudo-octahedral with the two chloride ions cis. The Fe-Cl bond trans to the tertiary amine is shorter. [{Fe(TPA)Cl}(2)O](ClO4)(2) exhibits two polymorphic monoclinic forms, and the monohydrate also crystallizes in a monoclinic form. For the P2(1)/c polymorph, Z = 2, a = 10.839(2) angstrom, b = 15.956(3) angstrom, c = 12.416(2) angstrom, beta = 107.024(10)degrees, and the structure was determined at 95 K from 6514 reflections (3974 observed) with R = 0.052 (R-w = 0.099).

Human extrahepatic and intrahepatic cholangiocyte organoids show region-specific differentiation potential and model cystic fibrosis-related bile duct disease

The development, homeostasis, and repair of intrahepatic and extrahepatic bile ducts are thought to involve distinct mechanisms including proliferation and maturation of cholangiocyte and progenitor cells. This study aimed to characterize human extrahepatic cholangiocyte organoids (ECO) using canonical Wnt-stimulated culture medium previously developed for intrahepatic cholangiocyte organoids (ICO). Paired ECO and ICO were derived from common bile duct and liver tissue, respectively. Characterization showed both organoid types were highly similar, though some differences in size and gene expression were observed. Both ECO and ICO have cholangiocyte fate differentiation capacity. However, unlike ICO, ECO lack the potential for differentiation towards a hepatocyte-like fate. Importantly, ECO derived from a cystic fibrosis patient showed no CFTR channel activity but normal chloride channel and MDR1 transporter activity. In conclusion, this study shows that ECO and ICO have distinct lineage fate and that ECO provide a competent model to study extrahepatic bile duct diseases like cystic fibrosis.

Pharmacologycal activity of peperina (Minthostachys verticillata) on gastrointestinal tract

Ethnopharmacological relevance: Minthostachys verticillata (Griseb.) Epling (Lamiaceae), known as Peperina is a medicinal native plant, with a traditional use as a digestive, antispasmodic and antidiarrheic. Aim Of The Study: Despite its folkloric use, no scientific evaluation of this plant related to the gastrointestinal inflammatory process has been carried out to date. The present study aims to assess the effects of M. verticillata on gastrointestinal system in experimental models. Materials and methods: M. verticillata (250 and 500 mg/kg) was orally tested in a colitis model induced by acetic acid. Colon weight/length ratio, oxidative stress (oxidized and reduced glutathione), histological changes using Alcian blue and hematoxylin & eosin staining and expression of IL1 beta, TNF alpha, iNOS, COX-2 were evaluated. The effect of the extract in three additional in vivo models were studied: intestinal motility and diarrhea induced by ricin oil, and visceral pain induced by intracolonic administration of capsaicin. Finally, the activity on concentration response curves of acetylcholine, calcium chloride, potassium and serotonin were achieved in isolated rat jejunum. Results: In the colitis model, M. verticillata induced a significant reduction in the colon weight/length ratio, oxidative stress and expression levels of IL-1 beta, iNOS and COX-2. Also, the extract diminished the severity of microscopic tissue damage and showed protective effect on goblet cells. Intestinal motility, diarrhea, visceral pain-related behaviors and referred hyperalgesia were significantly reduced when the animals were treated with the extract. Furthermore, in isolated jejunum, M. verticillata significantly reduced the contraction induced by serotonin and acetylcholine. Likewise, the extract non-competitively inhibited the response-concentration induced by CaCl2 and inhibited both low and high K+-induced contractions. Conclusions: This is the first study to validate traditional use of M. verticillata for digestive disorders and demonstrated that its aqueous extract could represent a promising strategy in targeting the multifactorial pathophysiology of inflammatory bowel disease.

Protective effect of Feijoa sellowianan fruit on testicular toxicity-induced by cadmium chloride

The purpose of the present study was to investigate the protective potential of Feijoa fruit extract on cadmium chloride (CdCl2)-induced testicular injury and pituitary-gonadal axis. Adult male Wistar rats were randomly divided into four groups: (a) control (normal saline, orally), (b) cadmium chloride (0.1 mg/kg, single dose, intraperitoneally), (c) Feijoa fruit extract (400 mg/kg, orally for 30 consecutive days) and (d) CdCl2 + Feijoa fruit extract. One day after receiving the last medicine, the LH, FSH, prolactin and testosterone concentration were assayed. Also, sperm parameters and tissue structure of the testis were evaluated. Administration of Feijoa fruit extract after CdCl2 injection in rats ameliorated sperm parameters such as sperm count, morphology, motility and sperm viability, increased levels of LH, FSH, prolactin and testosterone and improved testicular histology. According to the results of this study, it was shown that Feijoa can reduce the destructive side effects of CdCl2 on testicular tissue and sex hormones of the pituitary-gonadal pathway.

A facile synthesis of pyrano[2,3-d:6,5-d ‘]dipyrimidines via microwave-assisted multicomponent reactions catalyzed by beta-cyclodextrin

A facile three-component reaction of aromatic aldehyde, 2,2-dimethyl-1,3-dioxane-4,6-dione, and 6-amino-1,3-dimethyluracil was developed for the first time using beta-cyclodextrin (beta-CD) as a macrocyclic host for aldehyde and an efficient catalyst that leads to a batch of novel pyrano[2,3-d:6,5-d ‘]dipyrimidines (4a-k). The synthesis was accomplished with the aid of microwave irradiations in solvent-free conditions. The product obtained was in contrast to the previous report in which a similar reaction resulted in a mixture of benzylidenepyrimidine and bisaminopyrimidine analogs in the presence of triethylbenzylammonium chloride in an aqueous medium. The formation of the pyrano[2,3-d:6,5-d ‘]dipyrimidines may be in virtue of the property of beta-CD to construct new C-C and C-X (where X = heteroatom) bonds. Reusability of the catalyst up to three runs without any noteworthy change in catalytic activity is one of the main features of the reaction. Other noteworthy features are good to excellent yields, eco-friendly procedure, non-column chromatographic purification, and mild conditions.
