Boronic Ester Based Vitrimers with Enhanced Stability via Internal Boron-Nitrogen Coordination

Boron-containing polymers have many applications resulting from their prominent properties. Organoboron species with reversible B-O bonds have been successfully employed for the fabrication of various self-healing/healable and reprocessable polymers. However, the application of the polymers containing boronic ester or boroxine linkages is limited because of their instability to water. Herein, we report the hydrolytic stability and dynamic covalent chemistry of the nitrogen-coordinating cyclic boronic diester (NCB) linkages, and a new class of vitrimers based on NCB linkages is developed through the chemical reactions of reactive hydrogen with isocyanate. Thermodynamic and kinetic studies demonstrated that NCB linkages exhibit enhanced water and heat resistance, whereas the exchange reactions between NCB linkages can take place upon heating without any catalyst. The model compounds of NCBC-X1 and NCBC-X2 containing a urethane group and urea group, respectively, also showed higher hydrolytic stability compared to that of conventional boronic esters. Polyurethane vitrimers and poly(urea-urethane) vitrimers based on NCB linkages exhibited excellent solvent resistance and mechanical properties like general thermosets, which can be repaired, reprocessed, and recycled via the transesterification of NCB linkages upon heating. Especially, vitrimers based on NCB linkages presented improved stability to water and heat compared to those through conventional boronic esters because of the existence of N -> B internal coordination. We anticipate that this work will provide a new strategy for designing the next generation of sustainable materials.

Evaluation of the heat release rate during the combustion process in the diesel engine chamber powered with fuel from renewable energy sources

The article describes the results of combustion of a mixture of PCOME (purified cooking oil esters) and bioethanol in the compression ignition Perkins 1104C-44 engine. The engine was prepared for use with the classic type of fuel – diesel oil, not biofuels. That is why bioethanol was added to ester in tests so that the basic physicochemical properties of the obtained mixture were as close as possible to diesel fuel. Thanks to this, the use of such fuel in the future would not require reworking or adjusting the settings of selected elements of the engine power supply system. During this case study, the engine performance and heat release rate were analyzed. For comparison, tests were carried out while powering the engine with ester fuel, 10 and 20 per cent mixtures of bioethanol and PCOME. The speed and load characteristics for each fuel were determined. This article presents selected characteristics where the biggest differences were noticed.

Virulence profiles of some Pseudomonas aeruginosa clinical isolates and their association with the suppression of Candida growth in polymicrobial infections

Pseudomonas aeruginosa is an opportunistic pathogen that can cause a variety of diseases especially in the hospital environment. However, this pathogen also exhibits antimicrobial activity against Gram-positive bacteria and fungi. This study aimed to characterize different virulence factors, secreted metabolites and to study their role in the suppression of Candida growth. Fifteen P. aeruginosa isolates were tested for their anticandidal activity against 3 different Candida spp. by the cross-streak method. The effect on hyphae production was tested microscopically using light and scanning electron microscopy (SEM). Polymerase chain reaction was used in the detection of some virulence genes. Lipopolysaccharide profile was performed using SDS-polyacrylamide gel stained with silver. Fatty acids were analyzed by GC-MS as methyl ester derivatives. It was found that 5 P. aeruginosa isolates inhibited all tested Candida spp. (50-100% inhibition), one isolate inhibited C. glabrata only and 3 isolates showed no activity against the tested Candida spp. The P. aeruginosa isolates inhibiting all Candida spp. were positive for all virulence genes. GC-Ms analysis revealed that isolates with high anticandidal activity showed spectra for several compounds, each known for their antifungal activity in comparison to those with low or no anticandidal activity. Hence, clinical isolates of P. aeruginosa showed Candida species-specific interactions by different means, giving rise to the importance of studying microbial interaction in polymicrobial infections and their contribution to causing disease.

Synthesis of Macroheterocycles Containing Pyridine-2,6-dicarboxylic and Adipic Acid Ester and Hydrazide Fragments Starting from Tetrahydropyran

Efficient methods have been developed for the synthesis of three potentially useful macroheterocycles containing pyridine-2,6-dicarboxylic and adipic acid ester and hydrazide fragments starting from tetrahydropyran (commercial petrochemical product) through intermediate 8-hydroxyoctan-2-one. The key stages were [2+1]-condensation of the latter with pyridine-2,6-dicarboxylic and adipic acid chlorides and [1+1]-condensation of the resulting alpha,omega-diketo diesters with dihydrazides derived from the same diacids. The structure of the synthesized compounds was confirmed by IR, NMR, and mass spectra.

Novel mutant camelina and jatropha as valuable feedstocks for biodiesel production

Novel mutant camelina has become a crop of interest inspired by its short growing season, low harvesting costs and high oil composition. Despite those advantages, limited research has been done on novel mutant lines to determine applicability for biodiesel production. Jatropha is an extremely hardy, frugal and high oil yielding plant species. The major aim of the present study was not only to compare biodiesel production from jatropha and camelina but was also to test the efficacy of camelina mutant lines (M6 progenies) as superior feedstock. The biodiesel yield from camelina oil and jatropha oil was 96% and 92%, respectively. The gas chromatographic analysis using flame ionization detector (GC-FID) showed that mutant camelina oil biodiesel sample contain major amount of oleic acid (46.54 wt%) followed by linolenic acid (20.41 wt%) and linoleic acid (16.55 wt%). Jatropha biodiesel found to contain major amount of oleic acid (45.03 wt%) followed by linoleic acid (25.07 wt%) and palmitic acid (19.31 wt%). The fuel properties of produced biodiesel were found in good agreement with EN14214 and ASTM D6751 standards. The mutant camelina lines biodiesel have shown comparatively better fuel properties than jatropha. It has shown low saponification value (120.87-149.35), high iodine value (130.2-157.9) and better cetane number (48.53-59.35) compared to jatropha biodiesel which have high saponification value (177.39-198.9), low iodine value (109.7-123.1) and lesser cetane number (47.76-51.26). The results of the present student of utilizing novel mutant camelina lines for biodiesel production are quite promising and are helpful in turning out the outcomes of the previous studies suggesting that C. sativa biodiesel presents serious drawbacks for biodiesel applications.

Switching from Biaryl Formation to Amidation with Convoluted Polymeric Nickel Catalysis

A stable, reusable, and insoluble poly(4-vinylpyridine) nickel catalyst (P4VP-NiCl2) was prepared through the molecular convolution of poly(4-vinylpyridine) (P4VP) and nickel chloride. We proposed a coordination structure of the Ni center in the precatalyst based on elemental analysis and Ni K-edge XANES, and we confirmed that it is consistent with Ni K-edge EXAFS. The Suzuki-Miyaura-type coupling of aryl halides and arylboronic esters proceeded using P4VP-NiCl2 (0.1 mol % Ni) to give the corresponding biaryl compounds in up to 94% yield. Surprisingly, when the same reaction of aryl halides and arylboronic acid/ester was carried out in the presence of amides, the amidation proceeded predominantly to give the corresponding arylamides in up to 99% yield. In contrast, the reaction of aryl halides and amides in the absence of arylboronic acid/ester did not proceed. P4VP-NiCl2 successfully catalyzed the lactamization for preparing phenanthridinone. P4VP-NiCl2 was reused five times without significant loss of catalytic activity. Pharmaceuticals, natural products, and biologically active compounds were synthesized efficiently using P4VP-NiCl2 catalysis. Nickel contamination in the prepared pharmaceutical compounds was not detected by ICP-MS analysis. The reaction was scaled to multigrams without any loss of chemical yield. Mechanistic studies for both Suzuki-Miyaura and amidation were performed.

Plasticizers as Microplastics Tracers in Tunisian Marine Environment

The new knowledge on the bio-transformations to which the plastic material is subjected, raise concerns about their role as environmental contaminants. Microplastic have been reported to be responsible for the release and distribution of aquatic contaminants such organophosphorus esters, pesticides, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, and phthalate esters. The occurrence, spatiotemporal trends, and ecological risk of phthalic acid esters (PAEs) and non phthalate plasticizers (NPPs) released from microplastic were investigated in water and fish (Sparus aurata) from five sites along the coast of Mahdia governorate (Tunisia), during April 2018-March 2019. In seawater the most abundant and frequently detected congeners were dibutyl phthalate (DBP, 0.017 mg L-1 and 0.055 mg L-1), diisobutyl phthalate (DiBP, 0.075 mg L-1 and 0.219 mg L-1), di(2-ethylhexyl)phthalate (DEHP, 0.071 mg L-1 and 4.594 mg L-1), and di(2-ethylhexyl) terephthalate (DEHT, 0.634 mg L-1 and 2.424 mg L-1). (EPAEs: 1.416 mg L-1 and 5.581 mg L-1; ENPPs: 9.191 mg L-1 and 26.296 mg L-1), confirming that such compounds bioconcentrate through the food chain. DBP (0.389 and 0.817 mg L-1), DiBP (0.101 and 0.921 mg L-1), DEHP (0.726 and 1.771 mg L-1) and DEHT (9.191 and 23.251 mg L-1) were predominant also in S. aurata affirming that such compounds bioconcentrate through the food chain. Overall, Tunisian samples i) were much more contaminated than counterparts previously investigated for the same pollutants from other world areas, and ii) revealed NPPs at higher levels than PAEs, confirming that such plasticizers are increasingly replacing conventional PAEs.

Comparing different extraction methods for the investigation of red pepper (Capsicum annuum L.) volatiles

Different SPME fibres and distillation techniques (steam distillation and simultaneous distillation extraction) were applied to extract the volatile constituents of special quality sweet, ground red pepper. Preparation methods produced substantially different scent aromagrams recorded with GC-MS. Each procedure showed individual character. Distillation methods were the most effective ones considering the number and sum of peak intensities. Esters, terpenes, carotenoid derivatives and benzene components were the most intense volatiles. Among the SPME fibres PDMS-DVB showed the highest general sensitivity in those chemical classes that are crucial from varietal characterization and quality description aspects. In case of lactones and furans of high smell activities and fruity/sweet nuance, Carboxen-PDMS fiber seemed acceptably good. PDMS fibre was not really proper for paprika scent analysis and Polyacrylate practically could not be used at all. Comparison of SPME and distillation results permits to recognize and circumscribe the artefacts are induced by the distillation steps of the sampling procedure.

Synthesis of boronophenylalanine-like aza-amino acids for boron-containing azapeptide precursors

Aza-amino acids and an azapeptide with a boron-containing substituent were developed for the first time. We synthesized p-boronophenylalanine (BPA)-like aza-amino acid (aza-BPA) and its analogs in which the alpha-carbon of the peptide is replaced by nitrogen and the boronate ester is situated at the ortho, meta, or para position of the phenyl group. The N- and C-terminals of aza-BPA were linked to alpha-amino acids to afford an alpha/aza/alpha-tripeptide. These compounds are expected to be used in boron neutron capture therapy, chemotherapy, and synthesis of functional materials. (C) 2020 Elsevier Ltd. All rights reserved.
