Ameen, Ahmed W.;Ji, Jing;Tamaddondar, Marzieh;Moshenpour, Sajjad;Foster, Andrew B.;Fan, Xiaolei;Budd, Peter M.;Mattia, Davide;Gorgojo, Patricia research published 《 2D boron nitride nanosheets in PIM-1 membranes for CO₂/CH₄ separation》, the research content is summarized as follows. Phys. aging represents one of the major obstacles towards adoption of polymer of intrinsic microporosity (PIM) membranes for gas separation applications. In this work, mixed matrix membranes (MMMs) of 2D boron nitride nanosheets (BNNS) and PIM-1 were prepared and applied in the separation of a CO₂/CH₄ (1:1, v:v) binary gas mixture The membranes were tested over a period of more than one year to evaluate their anti-aging properties as compared to neat PIM-1. The results show that introducing BNNS into PIM-1 leads to a significant reduction in the phys. aging of PIM-1, as demonstrated by the values of reduction in CO₂ permeability after 414 days (22% for the MMMs as compared to 58% for neat PIM-1). This work paves the way to using PIM-based membranes in industry.

Alshahrani, Hassan;Dayo, Abdul Qadeer;Liu, Wen-bin research published 《 Development of chopped glass fiber composites with difunctional benzoxazine and bio-based phthalonitrile copolymer: A study of mechanical and thermomechanical properties》, the research content is summarized as follows. The randomly-oriented glass fibers (GF) reinforced composites with Bisphenol A-amine based benzoxazine (BA-a) and bio-based eugenol-based phthalonitrile (EPN) copolymer were developed by an isothermal compression molding technique. The silane coupling agent-treated GF (TGF) reinforced composites showed much better impact strength as compared to as-received GF reinforced composites. A rise of 95.2 MPa, 5.5GPa, 69.1 MPa, and 2.5GPa in flexural strength, flexural modulus, tensile strength, and Young’s modulus were observed, resp. The DMA results confirmed that the storage modulus (E’) and glass transition temperature (Tg) were gradually increased and the damping factor decreased as the TGF reinforcement was raised from 0 to 40 weight%. E’ and T_g values were 3.09 GPa and 27°C, resp., higher than the recorded values for the neat copolymer. The 40 weight% TGF reinforced poly(BA-a/EPN) composite showed the maximum thermal stability values of 475.4, 507.3°C, and 75.43% for T5, T10, and Yc, resp. The LOI values confirm that the TGF/copolymer composites have self-extinguishing properties.

Aljaddua, Huda I.;Alhumaimess, Mosaed S.;Hassan, Hassan M. A. research published 《 CaO nanoparticles incorporated metal organic framework (NH₂-MIL-101) for Knoevenagel condensation reaction》, the research content is summarized as follows. Porous materials based on NH₂-MIL-101(Cr) MOF and their hierarchical acid-base composite with non-precious CaO was successfully prepared using a one-pot scalable hydrothermal approach. The composites were characterized by XRD, FTIR, UV-vis, 1HNMR, TGA, N₂ adsorption-desorption isotherms, HRTEM and FESEM. The quant. assessment of the basic sites was performed by benzoic acid titration The results reveal that there is no remarkable structural alterations in the NH₂-MIL-101(Cr) after incorporation of CaO. Raising the CaO content boosted the strength of and content of Lewis basic sites from 0.31 to 1.34 mmol g^-1 due to the incorporation with CaO (0.04). Knoevenagel condensation reactions were performed as the probe reactions over the CaO/NH₂-MIL-101(Cr) catalysts. Both basic and acidic sites potentially boosted the reaction. Pure NH₂-MIL-101(Cr) display the catalytic conversion in the reaction (11%) which could be attributed weak basic sites on the NH₂-MIL-101(Cr) framework. However, the conversion (%) was potentially increased over NH₂-MIL-101(Cr) loaded with various content of CaO. The highest performance of (99%) conversion was achieved for (0.04) CaO/NH₂-MIL-101(Cr) catalyst. Exceptional conversion above 90% have been obtained for benzaldehyde derivatives both withdrawing and donating electron moieties. The composites can be recycled in four runs with a very small loss in performance. Furthermore, the composites produced tend to be feasible for various catalytic processes, exploring new avenues to produce of novel inorganic and organic composite materials as heterogeneous catalysts.

In this study, we report the synthesis and characterization of peripheral alkyl chain-substituted metalophthalocyanines [CuPc (3), ZnPc (4), and CoPc (5)] as optically sensitive substances with antifungal and antibacterial properties. Synthesized compounds were characterized by using common spectroscopic methods such as ¹H NMR, ¹³C NMR, FT-IR, MALDI-TOF, fluorescence, and UV-Vis spectroscopy. Aggregation behaviors of phthalocyanines in the presence of Ag⁺ and Pd²⁺ ions were investigated by UV-Vis and fluorescence spectroscopy.

Alepee, Nathalie;Leblanc, Virginie;Grandidier, Marie-Helene;Teluob, Severine;Tagliati, Valerie;Adriaens, Els;Michaut, Valerie research published 《 Development of the SkinEthic HCE Time-to-Toxicity test method for identifying liquid chemicals not requiring classification and labelling and liquids inducing serious eye damage and eye irritation》, the research content is summarized as follows. This study describes the development of a Time-to-Toxicity approach for liquids (TTL) based on the SkinEthic HCE tissue construct, capable to distinguish chems. that do not require classification for serious eye damage/eye irritation (No Cat.) from chems. that require classification for eye irritation (Cat. 2), and serious eye damage (Cat. 1). Briefly, the Time-to-Toxicity of 56 liquids was evaluated by exposing SkinEthic HCE tissue constructs to the test chem. for three different time periods (5-min, 16-min, and 120-min). Based on the viability observed for the different exposure periods, a classification was assigned. The within laboratory reproducibility in terms of concordance in classifications (3 UN GHS categories), based on a set of 50 liquids, was 80.0%. Furthermore, 84.3% Cat. 1 (N = 17), 79.4% Cat. 2 (N = 21) and 72.2% No Cat.(N = 18) were correctly identified with the SkinEthic HCE TTL test method. This study provides evidence that the SkinEthic HCE Time-to-Toxicity method (multiple exposure times) is capable of distinguishing Cat. 2 liquids from Cat. 1 liquids This is an advantage compared to the SkinEthic HCE EITL method (single exposure time) that can distinguish No Cat. chems. from chems. that do require classification and labeling for eye irritation/serious eye damage (Cat. 2/Cat. 1).

Akkoc, Berkay;Samsunlu, Taylan;Isik, Seyma;Ozcesmeci, Mukaddes;Atmaca, Goknur Yasa;Erdogmus, Ali;Serhatli, Muge;Hamuryudan, Esin research published 《 Pegylated metal-free and zinc(II) phthalocyanines: synthesis, photophysicochemical properties and in vitro photodynamic activities against head, neck and colon cancer cell lines》, the research content is summarized as follows. In this study, a series of peripherally and non-peripherally tetra-substituted metal-free and zinc(II) phthalocyanines were successfully prepared in good yields by cyclotetramerization of the phthalonitrile derivative bearing a tetraethylene glycol Me ether group at 3- and 4- positions. All newly synthesized compounds were characterized using spectroscopic methods, such as FT-IR, NMR, mass and UV-Vis spectroscopy. To determine the therapeutic potential of the synthesized phthalocyanines, the effects of the substitution pattern (peripheral and non-peripheral) and central metal atom on the photophysicochem. properties were investigated. When comparing their singlet oxygen generation capabilities (Φ_Δ), metallo-phthalocyanine derivatives with zinc (0.73 for 1b and 0.70 for 2b) showed higher singlet oxygen yield than metal-free derivatives (0.21 for 1a and 0.12 for 2a) in DMSO. The photodynamic therapy activities of the water-soluble phthalocyanines were tested via in vitro studies using the A253, FaDu (head and neck cancer cell lines), and HT29 (colon cancer) cell lines. The strongest photodynamic activity was found in 1b and 2b mols. with a metal core among the four mols. studied. The results suggested that the non-peripherally tetra-substituted 1b mol. was regarded as a suitable photodynamic therapy agent due to its light cytotoxicity and secondary impact induced by ROS production
