Diphenylborinic acid serves as a cocatalyst for site- and stereoselective C-H alkylation reactions of carbohydrates under photoredox conditions using quinuclidine as the hydrogen atom transfer mediator. Products arising from selective abstraction of the equatorial hydrogens of cis-1,2-diol moieties, followed by C-C bond formation with net retention of configuration, are obtained. Computational modeling supports a mechanism involving formation of a tetracoordinate borinic ester, which accelerates hydrogen atom transfer with the quinuclidine-derived radical cation through polarity-matching and/or ion-pairing effects.

Marine sponges are recognized as valuable sources of bioactive metabolites and renowned as petri dishes of the sea, providing specialized niches for many symbiotic microorganisms. Sponges of the family Dysideidae are well documented to be chemically talented, often containing high levels of polyhalogenated compounds, terpenoids, peptides, and other classes of bioactive small molecules. This group of tropical sponges hosts a high abundance of an uncultured filamentous cyanobacterium, Hormoscilla spongeliae. Here, we report the comparative genomic analyses of two phylogenetically distinct Hormoscilla populations, which reveal shared deficiencies in essential pathways, hinting at possible reasons for their uncultivable status, as well as differing biosynthetic machinery for the production of specialized metabolites. One symbiont population contains clustered genes for expanded polybrominated diphenylether (PBDE) biosynthesis, while the other instead harbors a unique gene cluster for the biosynthesis of the dysinosin nonribosomal peptides. The hybrid sequencing and assembly approach utilized here allows, for the first time, a comprehensive look into the genomes of these elusive sponge symbionts. IMPORTANCE Natural products provide the inspiration for most clinical drugs. With the rise in antibiotic resistance, it is imperative to discover new sources of chemical diversity. Bacteria living in symbiosis with marine invertebrates have emerged as an untapped source of natural chemistry. While symbiotic bacteria are often recalcitrant to growth in the lab, advances in metagenomic sequencing and assembly now make it possible to access their genetic blueprint. A cell enrichment procedure, combined with a hybrid sequencing and assembly approach, enabled detailed genomic analysis of uncultivated cyanobacterial symbiont populations in two chemically rich tropical marine sponges. These population genomes reveal a wealth of secondary metabolism potential as well as possible reasons for historical difficulties in their cultivation.

Naphthalenediimide-based n-type polymeric semiconductors are extensively used for constructing high-performance all-polymer solar cells (all-PSCs). For such all-polymer systems, charge recombination can be reduced by using thinner active layers, yet suffering insufficient near-infrared light harvesting from the polymeric acceptor. Conversely, increasing the layer thickness overcomes the light harvesting issue, but at the cost of severe charge recombination effects. Here we demonstrate that to manage light propagation within all-PSCs, a thick bulk-heterojunction film of approximately 350 nm is needed to effectively enhance photo-harvesting in the near-infrared region. To overcome the severe charge recombination in such a thick film, a non-halogenic additive is used to induce a well-ordered micro-structure that inherently suppresses recombination loss. The combined strategies of light management and delicate morphology optimization lead to a promising efficiency over 10% for thick-film all-PSCs with active area of 1 cm(2), showing great promise for future large-scale production and application of all-PSCs.

Polybrominated diphenyl ethers (PBDEs) are a class of brominated flame retardants (BFRs), present in the environment, animals, and humans. Their levels, distribution, and human exposure have been studied extensively, and over the last decade, various legal measures have been taken to prohibit or minimize their production and use due to the increasing amount of evidence of their harmful effects on human and animal health.Our aim here was to make a comprehensive and up-to-date review of the levels and distribution of PBDEs in the aquatic environment, air, and soil, in indoor dust, and in humans. To fulfill this, we searched through Web of Science for literature data reported in the last five years (2015-2019) on levels of at least six key PBDE congeners in abovementioned matrices. According to our summarized data, significant PBDE mass concentrations/fractions are still being detected in various sample types across the world, which implies that PBDE contamination is an ongoing problem. Secondary sources of PBDEs like contaminated soils and landfills, especially those with electronic and electrical waste (e-waste), represent a particular risk to the future and therefore require a special attention of scientists.

Nano ferrites (AFe(2)O(4), A = Zn, Co, Mn, Cu) were supported on the surface of gamma-Al2O3 support by hydrothermal synthesis to prepare a series of novel composite catalysts (AFe(2)O(4)/gamma-Al2O3) for catalytic ozonation for elimination of high concentration toluene at ambient temperature. The characterization results showed that the high-purity nano-AFe(2)O(4) particles were uniformly loaded on mesoporous gamma-Al2O3. Further, it was confirmed that among the several catalysts prepared, the amount of oxygen vacancies (O-vs), Lewis acid sites (LAS), and BrOnsted acid sites (BAS) of the ZnFe2O4/gamma-Al2O3 catalyst were the highest. This meant that the ZnFe2O4/gamma-Al2O3 catalyst had a strong adsorption capacity for toluene and ozone (O-3), and had a strong catalytic activity. When the temperature was 293 K and the space velocity was 1500 h(-1), the mol ratio of O-3 to toluene was 6, the degradation rate of toluene (600 mg m(-3)) can reach an optimum of 99.8%. The results of electron paramagnetic resonance (EPR) and Fourier infrared (FT-IR) proved superoxide radicals and hydroxyl radicals by catalytic ozonation. Moreover, the GC-MS analysis results indicated that the toluene degradation began with the oxidation of methyl groups on the benzene ring, eventually producing CO2 and H2O. After repeated experiments, the toluene degradation rate remained stable, and the residual content of O-3 in each litre of produced gas was less than 1 mg L-1, thereby indicating that the ZnFe2O4/gamma-Al2O3 catalyst had excellent reusability and showed great potential for the treatment of toluene waste gas.

Safety of Diphenyl oxide. I found the field of Chemistry very interesting. Saw the article How protoporphyrinogen IX oxidase inhibitors and transgenesis contribute to elucidate plant tetrapyrrole pathway published in 2019.0, Reprint Addresses Riou, C (corresponding author), Univ Limoges, Lab Peirene EA7500, Fac Sci & Tech, 123 Ave Albert Thomas, F-87060 Limoges, France.. The CAS is 101-84-8. Through research, I have a further understanding and discovery of Diphenyl oxide.

Several families of herbicides, especially diphenyl ether (DPE) and pyrimidinedione, target the plant tetrapyrrole biosynthesis pathways and in particular one key enzyme, protoporphyrinogen IX oxidase (PPO). When plants are treated with DPE or pyrimidinedione, an accumulation of protoporphyrin IX, the first photosensitizer of this pathway, is observed in cytosol where it becomes very deleterious under light. Indeed these herbicides trigger plant death in two distinct ways: (i) inhibition of chlorophylls and heme syntheses and (ii) a huge accumulation of protoporphyrin IX in cytosol. Recently, a strategy based on plant transgenesis that induces deregulation of the tetrapyrrole pathway by up- or down-regulation of genes encoding enzymes, such as glutamyl-tRNA reductase, porphobilinogen deaminase and PPO, has been developed. Against all expectations, only transgenic crops overexpressing PPO showed resistance to DPE and pyrimidinedione. This herbicide resistance of transgenic crops leads to the hypothesis that the overall consumption of herbicides will be reduced as previously reported for glyphosate-resistant transgenic crops. In this review, after a rapid presentation of plant tetrapyrrole biosynthesis, we show how only PPO enzyme can be the target of DPE and how transgenic crops can be further resistant not only to herbicide but also to abiotic stress such as drought or chilling. Keeping in mind that this approach is mostly prohibited in Europe, we attempt to discuss it to interest the scientific community, from plant physiologists to chemists, who work on the interface of photosensitizer optimization and agriculture.

We report on the shape, composition (from Pt95Zn5 to Pt77Zn23), and surface chemistry of Pt-Zn nanoparticles obtained by reduction of precursors M2+(acac) (-)(2) (M2+: Pt2+ and Zn2+) in oleylamine, which serves as both solvent and ligand. We show first that the addition of phenyl ether or benzyl ether determines the composition and shape of the nanoparticles, which point to an adsorbate-controlled synthesis. The organic (ligand)/inorganic (nanoparticles) interface is characterized on the structural and chemical level. We observe that the particles, after washing with ethanol, are coated with oleylamine and the oxidation products of the latter, namely, an aldimine and a nitrile. After exposure to air, the particles oxidize, covering themselves with a few monolayer thick ZnO film, which is certainly discontinuous when the particles are low in zinc. Pt-Zn particles are unstable and prone to losing Zn. We have strong indications that the driving force is the preferential oxidation of the less noble metal. Finally, we show that adsorption of CO on the surface of nanoparticles modifies the oxidation state of amine ligands and attribute it to the displacement of hydrogen adsorbed on Pt. All the structural and chemical information provided by the combination of electron microscopy and X-ray photoelectron spectroscopy allows us to give a fairly accurate picture of the surface of nanoparticles and to better understand why Pt-Zn alloys are efficient in certain electrocatalytic reactions such as the oxidation of methanol.

Thermal release of guest molecules from poly(2,6-dimethyl-1,4-phenylene)oxide (PPO) films, exhibiting host-guest cocrystalline (CC) phases with orientation of their chain axes being preferentially parallel or perpendicular to the film plane (c(parallel to) and c(perpendicular to) orientations), is studied. TGA analyses show that, for all the considered CC PPO films, temperatures of guest release for CC films with c(parallel to) orientation are definitely higher than those for CC films with c(perpendicular to) orientation, with differences even higher than 100 degrees C. Correspondingly, DSC scans of CC films with c(perpendicular to) orientation show separated endothermic peaks of guest release and melting, while CC films with c(parallel to) orientation only exhibit one broad endothermic peak with superimposed guest release, glass transition (T-g), and melting (T-m) phenomena. This control of temperatures of guest release could be helpful to maximize the thermal stability of host-guest PPO co-crystalline phases and to tailor temperatures of active guest release.

Degradability of biomaterials brings many opportunities as well as great challenges to their clinical applications. However, reports of systematic in vivo biodegradation are rather limited due to lack of adequate methodology for real-time observations. Herein, a tri-modal bioimaging technique is developed, enabling real time monitoring of biodegradation of synthetic polymers in vivo. The demonstrated material is a successful preclinical poly(lactic acid-co-glycolic acid)-b-poly(ethylene glycol)-b-poly(lactic acid-co-glycolic acid) thermosensitive hydrogel that undergoes a spontaneous sol-gel transition upon heating. A macromolecular fluorescence probe and a contrast agent of magnetic resonance imaging (MRI) are designed and synthesized. After subcutaneous injection of the hydrogel containing the two probes into mice, the degradation behaviors of the material are longitudinally and noninvasively tracked via the collaborative application of ultrasound, fluorescence, and MRI. Integrating the noninvasive imaging with the traditional anatomic observations, a three-stage degradation mechanism of such a hydrogel is proposed for the first time. Also, the dissolved polymers and degradation products in the body are mainly eliminated via liver, gallbladder, and spleen. This work has great value for promoting the future clinical application of these kind of promising hydrogels. Meanwhile, this technological platform provides beneficial inspiration and methodology to investigate in vivo fate of biomaterials.
