A novel halogen- and phosphorus-free intrinsic flame-retardant foam is fabricated from curable phenol-terminated polyphenylene ether resin with a high molecular weight using phenol, formaldehyde, and diphenyl ether as starting materials. The limiting oxygen index (LOI) of the pure foam is 24.90% +/- 0.28. When 0.5 wt % silica sol is added, the LOI of the foam (SPF-0.5) is up to 28.5% +/- 0.15 and both the combustion heat release rate and total combustion heat are low. Moreover, the SPF-0.5 foam exhibits high carbon residue, high compressive strength, and low pulverization rate and is superior to some previously reported phenolic foam. The flame-retardant mechanism includes the condensed-phase flame retardation and the gas-phase flame retardation, with the former being the main step, which is based on the high cross-linking density, the higher strength and smaller size of foam cells, and the formation of a carbon-silicon compound in the foam. This halogen- and phosphorous-free flame-retardant foam is also environmentally benign.

Bio-based aromatic polyketones (PKs) and polyetherketones (PEKs) were synthesized by the electrophilic substitution reaction of alkoxylated divanillic acid (R-DVA) and 2,2′-dimethoxybiphenyl or diphenylether. Alkoxy side-chains were introduced at the hydroxyl groups of DVA prior to polymerization. Polymerizations were carried out in a phosphorus pentoxide (P2O5)/methanesulfonic acid (MsOH) system. DVA-based PKs and PEKs were soluble in common organic solvents including chloroform and dimethylsulfoxide, and their chemical structures were determined by H-1 and C-13 NMR. The weight-average molecular weights (M-w) of the PKs were 2.6-15.0 x 10(3) g/mol, and those of all PEKs were approximately 1.0 x 10(3). The 10% degradation temperatures of the PKs and PEKs were 340-400 degrees C. Dynamic mechanical analysis showed that the PKs and PEKs were amorphous. The PKs with methyl to butyl side-chains exhibited high glass transition temperatures (T-g) in the range 250-297 degrees C, while T-g of PK (octyl side-chain) was 157 degrees C and those of the PEKs were 73-127 degrees C.

The aggregation of aromatic species is dictated by inter- and intramolecular forces. Not only is characterizing these forces in aromatic growth important for understanding grain formation in the interstellar medium, but it is also imperative to comprehend biological functions. We report a combined rotational spectroscopic and quantum-chemical study on three homo-dimers, comprising of diphenyl ether, dibenzofuran, and fluorene, to analyze the influence of structural flexibility and the presence of heteroatoms on dimer formation. The structural information obtained shows clear similarities between the dimers, despite their qualitatively different molecular interactions. All dimers are dominated by dispersion interactions, but the dibenzofuran dimer is also influenced by repulsion between the free electron pairs of the oxygen atoms and the pi-clouds. This study lays the groundwork for understanding the first steps of molecular aggregation in systems with aromatic residues.

Lignin is constructed from methoxylated phenylpropanoid with plenty of hydroxys and methoxys. Its conversion to valuable products is extremely attractive but especially challenging without additional hydrogen sources. Herein we report a hydrogen-free production of 4-alkylphenols directly from native lignin via self-reforming-driven depolymerization and hydrogenolysis over Pt/NiAl2O4. This is the first example of acquiring 4-alkylphenols from native lignin. Using this strategy, high yields of 4-alkylphenols, 17.3 wt %, were obtained from birch lignin. Reaction pathway and mechanism studies revealed that this strategy initiates from the reforming of aliphatic hydroxys, followed by the cleavage of C-O linkages, and ends via demethoxylation over Pt/NiAl2O4. Moreover, the subsequent aqueous phase reforming of the as-formed methanol accelerates the whole process. This strategy realizes the one-pot production of 4-alkylphenols from lignin by fully utilizing the structural hydrogen in lignin and H2O, providing a low-cost and safe method of lignin valorization.

Quantum dots (QDs) were suggested a decade ago as a means of spectral decoy to divert rocket attacks from flying objects such as satellites but have not yet found industrial applications. A possible reason is that these advanced nanomaterials are unstable in the long-term under the forces exhibited on a flying object and the nanoparticles might agglomerate to form larger microparticles, which have a different, unwanted spectral footprint. This work proposes an on-board (in situ) real-time synthesis of quantum dots on a satellite as a result of an interdisciplinary innovation that combines nanomaterial chemistry, heating and mixing with batch microfluidics, and microfabrication of a miniaturized chip. We employed a microchip as the in situ reaction chamber due to its capability of fast, compact synthesis. The implementation of the space micro-reactor, on the other hand, leads to other fundamental challenges that need to be solved such as robust pump-free fluid motion and quick synthesis of quantum dots in less than 180 s which is equivalent to the typical time a rocket needs to reach the satellite from the ground. Additionally, quantum dots need to be tailored in the type of material and size to replicate the spectral signal of the to-beprotected space asset while the synthesis process needs to be robust and resilient to work reliably and automatically under the demanding conditions of a flying object. In this study, we selected cadmium selenide (CdSe) and lead selenide (PbSe) as the materials of choice. Our synthesis process aims to simplify and tailor CdSe and PbSe quantum dots to match the above demands. The produced quantum dots were characterized by their wavelength emission spectra and high-angle annular dark-held scanning transmission electron microscopy (HAADF STEM) images. Results show that both CdSe and PbSe quantum dots have been successfully synthesized within a maximum of 10 minutes. While the chosen CdSe-based synthesis was unable to reach IR-emitting sizes within several minutes, we managed to meet all other research targets. The synthesized PbSe 013s were able to reach the mock-spectrum and could produce an emission wavelength peak from 1200 to 1400 nm. This work finally provides insights into the limits of batch synthesis in a microfabricated nanodot chip, such as the need to improve reproducibility and enhance particle growth. Based on this learning, we propose a self-priming flow microchip synthesis that can capitalize on mixing as a key asset to overcome those limits.

Hierarchical SAPO-18 molecular sieve was successfully post-synthesized in the alkaline tetraethyl ammonium hydroxide (TEAOH) solution and hydrochloride (HCl) acid solution. In the TEAOH solution, preferential dissolution occurs surrounding the defect sites in a controlled manner, leading to hierarchical SAPO-18 with wellpreserved chemical compositions and crystallinities. In acidic solution, the dissolution is revealed to be sensitive to both the defects and the chemical compositions (selective dissolution of the Si-O-Al domains), which cooperatively contribute to the generation of meso-/macropores in the crystals. The crystallization of SAPO-18 precursor is thus inferred to proceed via an oriented nanoparticle attachment mechanism in the early stage. The twinning and intergmwth of nanoparticles occur in an ordered way, leading to the oriented arrangement of the crystallite boundaries. The defects located at the intergrowth interface are prone to acid/alkaline attacks, and play crucial role in the development of hierarchical pore systems. The hierarchical SAPO-18 sample exhibits excellent catalytic reaction performance in the liquid phase benzylation reaction of benzene and benzyl alcohol.

A novel ferrierite type zeolite named as IEZ-Al-PLS-3(S4R) with pore sizes of 14 x 12-ring (R) was post synthesized by simply interlayer silylation of lamellar precursor Al-PLS-3 taking 1,3,5,7-tetramethylcyclosilone (TMCS) as silane. Its catalytic properties were tested by isomerization/disproportionation of m-xylene, alkylation/acylation of anisole with benzyl alcohol/acetic anhydride. The catalytic performance of IEZ-Al-PLS-3(S4R) was compared with Al-PLS-3 (10 x 8-R) and IEZ-Al-PLS-3(1Si) (12 x 10-R) which were prepared by calcination or silylation using dimethoxydimethylsilane (DEDMS) as silane of as made Al-PLS-3 respectively. Since these materials have the same laminates composition, the differences of catalytic performance can be considered as the result of different pore sizes. We also prepared conventional 10-R zeolite ZSM-5 and 12-R zeolite Beta for control experiments. IEZ-Al-PLS-3(S4R) showed even higher catalytic activities than Beta as a result of its enlarged 14-R pore size.

Despite typically not being taken into account (usually in favour of the ‘global distillation’ process), the input of persistent organic pollutants (POPS) through biological activities can be indeed relevant at the local scale in terrestrial polar environments when seabird colonies are considered. Seabirds can bio-accumulate and biomagnify POPs, gather in large numbers and excrete on land during their reproductive season, thus making them locally as relevant secondary sources of POPS. The first part of this study indicated that these colonies act as so for several essential and non-essential trace elements, and this second part tests the same hypothesis concerning POPS using the very same samples. Lichens (n = 55), mosses (n = 58) and soil (n = 37) were collected from 13 locations in the South Shetlands Archipelago during the austral summers of 2013-14 and 2014-15. They were divided in colony (within the colony itself for soil and within and surrounding the colony for vegetation) and control (at least 150 m away from any colony interference) and analysed for POPs such as organochlorine pesticides, polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers and stable isotopes (C and N). Results showed that colonies act clearly as a secondary source for PCBs and likely for hexachlorobenzene. As in the first part, probable local sources other than the colonies themselves are hypothesised because of high concentrations found in control sites. Again, soil seemed the most adequate matrix for the intended purposes especially because of some particularities in the absorption of animal-derived organic matter by vegetation, pointed out by stable isotope analyses.

In this work, we provide a detailed account of the liquid-phase exfoliation (LPE) of rhenium disulfide (ReS2), a promising new-generation two-dimensional material. By screening LPE in a wide range of solvents, we show that the most optimal solvents are characterized by similar Hildebrand or dispersive Hansen solubility parameters of 25 and 18 MPa1/2, respectively. Such values are attained by solvents such as N-methyl-2-pyrrolidone, N,N-dimethylformamide, and 1-butanol. In line with solution thermodynamics, we interpret the conditions for high-yield exfoliation as a matching of the solvent and ReS2 solubility parameters. Using N-methyl-2-pyrrolidone as an exemplary exfoliation solvent, we undertook a detailed analysis of the exfoliated ReS2. In-depth morphological, structural, and elemental characterization outlined that the LPE procedure presented here produces few-layer, anisotropically stacked, and chemically pure ReS2 platelets with long-term stability against oxidation. These results underscore the suitability of LPE to batch-produce few-layer and pristine ReS2 in solvents that have a solubility parameter close to 25 MPa1/2.

Microtubule targeting agents represent a very active arena in the development of anticancer agents. In particular, compounds binding at the colchicine site in tubulin are being deeply studied, and the structural information recently available on this binding site allows structure-directed design of new ligands. Structural comparison of our recently reported high resolution X-Ray structure of the cyclohexanedione derivative TUB075 bound to tubulin and the tubulin-DAMA-colchicine complex has revealed a conformational change in the alpha T5 loop. By a grid-based computational analysis of the tubulin-DAMA-colchicine binding site, we have identified a new favourable binding area in the colchicine-site that was unexplored by our lead TUB075. Thus, based on a structure-guided design, new cyclohexanedione derivatives have been synthesized and tested for tubulin binding and in cellular assays. As a result, we have identified diphenyl ether derivatives with IC50 values around 10-40 nM against three different tumor cell lines and affinity constants for tubulin similar to that of colchicine around 10(7) M-1. As expected, they halted the cell cycle progression at G2/M phase at concentrations as low as 0.08 mu M. (C) 2019 Elsevier Masson SAS. All rights reserved.
