Unusual Nanostructured Morphologies Enabled by Interpolyelectrolyte Complexation of Polyions Bearing Incompatible Nonionic Segments

The nanostructures of polyelectrolyte complexes (PECs) fabricated from a series of rationally designed oppositely charged amphiphilic random copolymers with variable comonomer compositions were studied experimentally in 50:50 (v/v) methanol-H2O mixtures through morpho- logical investigations. Both polycationic [poly(alanine methacryloyloxyethyl ester-co-styrene), P1-P4] and polyanionic [poly(acrylic acid-co-methyl acrylate), P1′-P4′] electrolytes were synthesized via reversible addition-fragmentation chain-transfer (RAFT) copolymerization while maintaining the mole fractions of charge-bearing groups within the range of 50-90%. Unlike polyanions, polycations showed well pronounced pH-responsive behavior owing to pH-induced protonation/deprotonation phenomena of pendant quaternary ammonium groups. On account of this fact, PEC formation with concomitant microphase separation was realized at pH 5.0 when all obtained compositions of both polycations and polyanions were totally soluble. Fine tuning of alanine-derived cationic and anionic acrylic acid compositions confers uncommon morphologies revealed by electron microscopic observations. Intriguingly, a string-of-beads like morphology was observed for PECs prepared with 50 and 60% charged ratios, whereas spherical micelles and vesicles were formed in the case of 70 and 90% ratios, respectively, attributed to the strength of electrostatic interaction and incompatibility of nonionic segments. These fascinating morphologies were further corroborated by computer simulations of two oppositely charged chains within a coarse-grained approach. A diagram of PEC morphologies was constructed depending on the hydrophobic/hydrophilic composition of polyions, fraction of ion-containing groups, and the strength of electrostatic interactions. Observation of these unique morphologies from a single pair of a polyelectrolyte system is scarcely reported in the literature.

Colorimetric alkaline phosphatase activity detection by integrating phosphorylation-mediated sulfydryl protection/deprotection and fluorosurfactant stabilized gold

Protection/deprotection of thiolates are widely used for the design of sensing systems by producing free sulfydryl (-SH) groups. However, most conventional protection/deprotection strategies reported so far suffer poor protection and/or difficult release of -SH group. In this study, phosphorylation/dephosphorylation strategy that exhibits efficient protection and facile liberation of -SH group via the formation of a phosphate-thiol ester, was utilized to develop colorimetric probe for alkaline phosphatase (ALP) activity evaluation. The proposed probe was composed of a cysteamine S-phosphate as a model thiolate substrate and Zonyl FSN-100 functionalized gold nanoparticles (FSN-AuNPs) as reporters. In the presence of ALP, the cysteamine S-phosphate hydrolyzed to generate cysteamine, which aggregated FSN-AuNPs with detectable spectroscopic changes through nanointerface interactions. The changes in UV-vis absorption spectroscopy allowed a detection limit of ALP at 0.1 unit/L. The specific enzyme catalytic hydrolysis provided high selectivity toward ALP over other proteins, small molecules, and metal ions. The practicability of the sensor was validated by accurate examination of ALP in blood samples. In addition, by integrating the conventional ELISA technique and the proposed phosphorylation tactic, sensitive immunoglobulin G detection was achieved.

The plasma lipidome of the Quaker parrot (Myiopsitta monachus)

Dyslipidemias and lipid-accumulation disorders are common in captive parrots, in particular in Quaker parrots. Currently available diagnostic tests only measure a fraction of blood lipids and have overall problematic cross-species applicability. Comprehensively analyzing lipids in the plasma of parrots is the first step to better understand their lipid metabolism in health and disease, as well as to explore new lipid biomarkers. The plasma lipidome of 12 Quaker parrots was investigated using UHPLC-MS/MS with both targeted and untargeted methods. Targeted methods on 6 replicates measured 432 lipids comprised of sterol, cholesterol ester, bile acid, fatty acid, acylcarnitine, glycerolipid, glycerophospholipid, and sphingolipid panels. For untargeted lipidomics, precursor ion mass-to-charge ratios were matched to corresponding lipids using the LIPIDMAPS structure database and LipidBlast at the sum composition or acyl species level of information. Sterol lipids and glycerophospholipids constituted the majority of plasma lipids on a molar basis. The most common lipids detected with the targeted methods included free cholesterol, CE(18:2), CE(20:4) for sterol lipids; PC(36:2), PC(34:2), PC(34:1) for glycerophospholipids; TG(52:3), TG(54:4), TG(54:5), TG(52:2) for glycerolipids; SM(d18:1/16:0) for sphingolipids; and palmitic acid for fatty acyls. Over a thousand different lipid species were detected by untargeted lipidomics. Sex differences in the plasma lipidome were observed using heatmaps, principal component analysis, and discriminant analysis. This report presents the first comprehensive database of plasma lipid species in psittacine birds and paves the way for further research into blood lipid diagnostics and the impact of diet, diseases, and drugs on the parrot plasma lipidome.

Defect engineering of polyethylene-like polyphosphoesters: solid-state NMR characterization and surface chemistry of anisotropic polymer nanoplatelets

Anisotropic materials with very high aspect ratios, such as nanoplatelets, are an exciting class of materials due to their unique properties based on their unilamellar geometry. Controlling their size and surface-functionality is challenging and has only be achieved in some cases for synthetic polymers. We present a general approach to prepare polymer-nanoplatelets with control over the lateral size and basal functionality, by simple polycondensation of precisely spaced and functional phosphate groups in polyethylene-like polymers. Because of the relatively large size of the phosphate groups, they are expelled from the bulk crystal to the basal surface. This allows to control the chain-folding during crystallization, which we analyzed via solid-state NMR and TEM. Furthermore, we present chemistry on the surface of the platelets: the pendant ester group at the phosphate offers the possibility to introduce functional groups accessible for further chemical modification on the crystal surface. This is shown by introducing a 2-acetylthioethyl ester group and subsequently cleaving this 2-acetylthioethyl ester group to the free P-OH. Together, these results render polyethylene-like polyphosphoesters a versatile platform for soft-matter nanoplatelets as functional colloids.

Selective Construction of C-C and C=C Bonds by Manganese Catalyzed Coupling of Alcohols with Phosphorus Ylides

Herein, we report the manganese catalyzed coupling of alcohols with phosphorus ylides. The selectivity in the coupling of primary alcohols with phosphorus ylides to form carbon-carbon single (C-C) and carbon-carbon double (C=C) bonds can be controlled by the ligands. In the conversion of more challenging secondary alcohols with phosphorus ylides the selectivity towards the formation of C-C vs. C=C bonds can be controlled by the reaction conditions, namely the amount of base. The scope and limitations of the coupling reactions were thoroughly evaluated by the conversion of 21 alcohols and 15 ylides. Notably, compared to existing methods, which are based on precious metal complexes as catalysts, the present catalytic system is based on earth abundant manganese catalysts. The reaction can also be performed in a sequential one-pot reaction generating the phosphorus ylide in situ followed manganese catalyzed C-C and C=C bond formation. Mechanistic studies suggest that the C-C bond was generated via a borrowing hydrogen pathway and the C=C bond formation followed an acceptorless dehydrogenative coupling pathway.

A unique pathway to platform chemicals: aldaric acids as stable intermediates for the synthesis of furandicarboxylic acid esters

2,5-Furandicarboxylic acid (FDCA) has received attention as an emerging bio-based building block with many applications, especially in renewable polyesters. The common route to FDCA uses the unstable 5-hydroxymethylfurfural (HMF) as an intermediate. Here, we present an alternative route to FDCA and its esters using C6 aldaric acids as stable intermediates. Aldaric acids, or sugar diacids, can be obtained by the oxidation of C6 sugars or uronic acids from pectin. Subsequent dehydration of aldaric acids by solid acid catalysts in butanol produces furancarboxylates. Using silica-supported acid catalysts, over 90% yields of furancarboxylates were achieved with the selectivity to FDCA and its esters reaching 80%.

Structurally Defined Ring-Opening and Insertion of Pinacolborane into Aluminium-Nitrogen Bonds of Sterically Demanding Dialkylaluminium Amides

Dialkylaluminium amides iBu(2)Al(TMP) and iBu(2)Al(HMDS) can perform catalytic hydroboration of ketones with pinacolborane to form the expected boronic esters. However, repeating the same reactions stoichiometrically without a ketone leads unexpectedly to ring-opening of pinacolborane and insertion of its open chain into the Al-N(amido) bond. To date there has been limited knowledge on decomposition pathways of HBpin despite its prominent role in hydroboration chemistry. X-ray crystallography shows these mixed Al-B products [iBu(2)Al{OC(Me)(2)C(Me)(2)O}B(H)(NR2)](2) (NR2=TMP or HMDS) form dimers with an (AlO)(2) core and terminal B-N bonds. Since the bond retention (B-H) and bond breaking (B-O) in these transformations seemed surprising, DFT calculations run using M11/6-31G(d,p) gave an energy profile consistent with a sigma-bond metathesis mechanism where London dispersion interactions between iBu and (amide) Me groups play an important stabilising role in the final outcome.

Synthesis of Chiral-Substituted 2-Aryl-ferrocenes by the Catellani Reaction

A palladium-catalyzed and norbornene-mediated methodology has been developed for the synthesis of chiral 2-aryl-ferroceneamides from chiral 2-iodo-N,N-diisopropylferrocencarboxamide, iodoarenes, and alkenes using a JohnPhos ligand and potassium carbonate as a base in dimethylformamide at 105 degrees C. The developed three-component coupling protocol allows the compatibility of electron-withdrawing fluoro, chloro, ester, and nitro and electron-donating methyl, methoxy, dimethoxy, benzyl ether-substituted iodo-benzenes, other iodoarenes, such as iodo-naphthalene, heteroarenes, such as iodothiophene, and terminating substrates, such as methyl, ethyl, tert-butyl acrylates, and substituted styrenes with 2-iodo-N,N-diisopropylferrocencarboxamide. Furthermore, the developed three-component Catellani method proceeded with the retention of the configuration of the planar chiral ferrocene, which depends on the role of the participating carbon-iodine bond in ferrocene. Consequently, the developed protocol enabled the formation of densely substituted chiral 2-aryl ferroceneamides, exhibiting good to excellent enantioselectivity. The conversion of an ester of the synthesized chiral 2-aryl ferroceneamides has also been carried out to further accommodate the easily expendable acid and alcohol functionalities.

Tuning the molar mass and substitution pattern of complex xylans from corn fibre using subcritical water extraction

Glucuronoarabinoxylan (GAX) is a structurally complex hemicellulose abundant in the cell wall of corn kernels that constitutes a valuable target for its valorisation from corn processing side streams. However, the crosslinked and recalcitrant nature of corn cell walls hinders its fractionation through mild green processes. In this study, we propose the extraction of GAX using subcritical water, where temperature, pH and time have been optimised to tune the extraction performance (yields and purity of the GAX) and the molecular structure of the extracted GAX (molar mass distribution, substitution pattern and presence of covalently bound phenolic moieties). Higher temperatures under unbuffered conditions caused a prominent drop in pH and autohydrolysis, resulting in a decrease of the molar mass (similar to 10(4) Da) and the cleavage of arabinose substitutions. Mitigating the pH drop using mild buffered neutral and alkaline conditions provided higher molar masses of the extracted GAX (similar to 10(5) Da), protecting as well the labile arabinose substitutions and resulting in a higher abundance of more complex glycan side chains. Subcritical water extraction preserved the phenolic acid moieties (mainly ferulic acid) covalently bound to polymeric GAX. Several forms of ferulic acid dehydrodimers (di-FA) were detected and identified by liquid chromatography-tandem mass spectrometry (HPLC-LC-MS2) and these di-FAs were particularly enriched in the mild alkaline extracts. We demonstrate that solely by carefully adjusting the operational parameters during subcritical water extraction we can tune the molar mass and complex substitutions of GAX, i.e. the degree and pattern of monomeric and oligomeric glycan side chains and ester-linked phenolic acid substitutions, without the use of additional catalysts. This molecular control over the production of corn GAX can invaluably benefit subsequent development of agroindustry-based biorefineries towards their conversion into novel bio-based materials for food and biomedical applications.

Comparison of three different analytical protocols for 2019 updated D2425 method for renewable jet fuel product certification analysis

ASTM standard specification D7566 covers the manufacture of synthetic aviation turbine fuel components and their blends with conventional Jet fuel (Jet A or Jet A-1). One of the components is renewable jet fuel (RJF) which is synthetic paraffinic kerosene (SPK) made from hydroprocessed esters and fatty acids (HEFA). The specification D7566 dictates property requirements for the SPK-HEFA, including concentration limits for selected hydrocarbon types (paraffins, cycloparaffins, and aromatics), which are analyzed by using the mass spectrometry (MS) based standard method D2425. The most recent update for D2425 released in 2019 includes the synthetic hydrocarbon sample type (e.g., SPK-HEFA) and defines various analytical procedures for the analysis. Notably, the procedures differ considerably from each other, and the experimental conditions are not defined in details. This leads to laboratories setting up analytical schemes for D2425 that are likely to differ from each other, which may result in variation in the quality of the results obtained in different laboratories. In the present study, the performances of D2425 analytical protocols set up by three laboratories were tested in certification analysis (D7566) of SPK-HEFA type RJF. The tested analytical protocols were proven to comply with the requirements of the 2019 version of the D2425 standard. Furthermore, the precisions of the protocols did not differ significantly from each other. However, a significant bias was found for the results obtained for cycloparaffins and aromatics. Further, considerable differences were found in the bias values between the laboratories. Based on the results of this study, the guidelines of the 2019 updated D2425 standard may result in setting up an analytical protocol for D2425 which may not be optimal for RJF certification.
