Gas permeation properties of three highly permeable perfluorinated polymers (polyhexafluoropropylene (PHFP), amorphous Teflon AF2400, and polyperfluoro(2-methyl-2-ethyl-dioxole-1,3) (PPFMED)), which are promising materials for the dense thin layer of hollow fiber membranes for extracorporeal membrane oxygenation have been studied using nitrogen, oxygen, and carbon dioxide. Hemocompatibility of the polymeric films has also been investigated on whole blood from healthy donors. Gas permeation of the polymers increases in the order PHFP < PPFMEDD < AF2400, with PHFP alone having the permeability coefficients of the gases do not below those of polydimethylsiloxane applied as the selective layer of blood oxygenation membranes. Hemocompatibility of the polymers declines in the order PHFP > PPFMED > AF2400, with the most permeable polymer AF2400 exhibiting the worst hemocompatibility among the other polymers studied. Polyperfluoro(2-methyl-2-ethyl-dioxole-1,3) is shown to be the most appropriate polymer to fabricate hollow fiber membranes for blood oxygenation.

Permeability coefficients of hydrogen sulfide in fluorinated polymers are anomalously low when compared to its permeability in nonfluorinated polymers. As a result, fluoropolymer membranes have unusual selectivities for gas pairs involving H2S. For example, while the mixture CO2/H2S selectivity is 0.66 for nonfluorinated, rubbery poly( dimethylsiloxane), this selectivity is 8.0 for a fluoroelastomer composed of tetrafluoroethylene, perfluoromethyl vinyl ether, and perfluoro-8-cyano-5-methyl-3,6-dioxa-1-octene (TFE/PMVE/ 8CNVE) and 27 for a glassy, cyclic perfluoroether (Cytop) under similar test conditions. The low H2S permeability in fluoropolymers is caused primarily by unexpectedly low H2S solubility in the fluorinated polymer matrices. For instance, H2S solubility in a Teflon AF copolymer of tetrafluoroethylene and 2,2-bis(trifluoromethyl)-4,5difluoro- 1,3-dioxole is approximately 5 times lower than the value predicted by a correlation of solubility with gas critical temperature. This low solubility is not related to penetrant size or condensability effects but rather is caused by unfavorable molecular interactions between H2S and fluoropolymers. As a result of this unusual solubility behavior, fluorinated glassy polymers are more resistant to H2S-induced plasticization than nonfluorinated glasses. These findings may prove useful in emerging membrane applications that involve H2S, such as natural gas treatment.

Molecular behavior of the building block ([2-(1,3-dithiole-2-ylidene)-1,3-dithiole] =tetrathiafulvalene (TTF)} of organic superconductors have been investigated along with its three derivatives, namely, {[2-(1,3-dioxole-2-ylidene)-1,3-dioxole] tetraoxafulvalene (TOF)}; [2,2]-bi-[[1,3] oxathiolylidene]=Der I and 2-(3H-Furan-2-ylidene)-[1,3] oxathiole=Der II. The properties of the molecules such as molecular geometries, frontier MOs and vibrational spectra have been investigated by using DFT method at the B3LYP level employing 6-311++G(d,p) basis set. The geometrical parameters and atomic charges on various atomic sites of the TTF, TOF, Ders land II suggest extended conjugation in these systems. The present calculations lead to the reassignments for of some of the fundamentals and new interpretations for some of the observed IR and Raman frequencies. One of the two modes involved in the Fermi resonance giving rise to the doublet 1555 and 1564 cm(-1) needed to be revised and another doublet 3083 and 3108 cm(-1) could be interpreted as a Fermi resonance doublet. Out of the two nu(C=C) modes under the a(1) species, the lower frequency mode is assigned to the nu(C=C) of the ring and the higher one to the nu(C=C) of the central C=C bond contrary to the assignment reported in literature. The conducting properties of these molecules depend mainly on this mode. (C) 2012 Elsevier B.V. All rights reserved.

Now introduce a scientific discovery about this category.

In this paper is presented a study on the effects of physical treatments, namely electron beam irradiation or fluorination, on a perfluoropolymer copolymer of tetrafluoroethylene with 2,2,4-trifluoro-5-trifluoromethoxy-1,3-dioxole (Hyflon (R) AD copolymer). The analysis has been carried out by means of IR spectroscopy and quantum chemical modeling based on density functional theory; this combined experimental/ theoretical approach has proven effective for the interpretation of previously unassigned IR bands, which are associated to functional groups generated by polymer degradation and chain scission. We performed a systematic screening of chemical groups and structures compatible with degradation pathways that are possible from the chemical point of view: the chemical mechanisms and the correlation with the spectroscopic experimental data (both frequency and intensity) provide guidelines in understanding the phenomena. Moreover, the spectroscopic experimental/theoretical and chemical approaches allowed us to identify some chemical structures responsible for the unassigned IR bands in the C=O stretching frequency region above 1800 cm(-1), which is typical for carbonyl groups in fluorinated systems.

Orobanche and Phelipanche species (the broomrapes) are root parasitic plants, some of which represent serious weed problems causing heavy yield losses on important crops. Current control relies on the use of certain agronomic practices, resistant crop varieties, and herbicides, albeit success has been marginal. Agronomic practices such as the use of allelopathic species in intercropping or cover crops, or the use of direct seedling over residues of allelopathic species incorporate the principle of allelopathy exerted by molecules exuded from roots or released by crop residues to control broomrapes. In addition, the isolation of natural substances from root exudates of plants with potential to inhibit broomrape development opens the door to the design of new herbicides based on natural and benign sources. Ryecyanatines A and B and ryecarbonitrilines A and B, the first new substituted cyanatophenol, substituted cyanatobenzo[1,3]dioxole, and the latter two new substituted benzo[1,3]dioxolecarbonitriles were isolated from rye (Secale cereale L.) root exudates. They were characterized as 4-cyanato-2-methoxyphenol, 2-cyanato-benzo[1,3]dioxole, 2-methoxybenzo[1,3]dioxole-5-carbonitrile and benzo[1,3]dioxole-2-carbonitrile by spectroscopic (essentially NMR and HRESI MS spectra) methods. These compounds were investigated for allelopathic activity on Orobanche germination and development. Ryecarbonitriline A induced germination of Orobanche cumana seeds, and this germination can be considered as suicidal because O. cumana does not parasite rye roots and cannot survive without host resources beyond germination stage. In addition, ryecyanatine A promotes a rapid cessation of O. cumana, Orobanche crenata and Orobanche minor radicle growth with the promotion of a layer of papillae at the radicle tip in O. cumana and O. crenata hampering the contact of the parasite to the host. Ryecarbonitriline B also displayed the same activity although being less active than ryecyanatine A and mainly restricted to O. cumana. (C) 2014 Elsevier Ltd. All rights reserved.

As the semiconductor community continues scaling, area selective atomic layer deposition (ASD) offers the potential to relax down stream processing steps by enabling self-aligned processes (e.g., self-aligned vias). Otherwise, conventional means of lithography face increasingly difficult challenges such as patterning and overlay errors as resolution improves. ASD can be achieved under a variety of conditions, and with the use of organic inhibiting materials, it can exhibit some of the highest levels of selectivity. However, the structure property relationship of these inhibiting materials is not completely understood, and therefore the relationship between a materials chemical functionality and its inhibiting properties remains largely unexplored. This was explored with polymeric materials that served as a versatile materials platform allowing a broad variation of chemical functional groups and physical properties that may then enable the ASD community to extend the number and types of films that can be selectively deposited. Initially, hydrophobic polymers including polystyrene (PS) and polyvinyl chloride (PVC), as well as an oleophobic polymer, poly [difluoro-bis(trifluoromethyo)-dioxole-co-tetrafluoroethylene] (PTFE-AF), were surveyed for their inhibitory properties toward the atomic layer deposition of industry relevant metal oxides such as Al2O3 and TiO2, which heavily feature as etch masks and other functional nanostructures. Despite blanket deposition of Al2O3 being observed, even when using an oleophobic polymer such as PTFE-AF, TiO2 deposition was notably inhibited by blanket films of PVC, PS, and PTFE-AF. In light of these results, the functionalization of PVC and PS with selective area substrate anchoring groups such as phosphonic acids (targeting copper oxide surfaces) was conducted to investigate whether grafting selectivity of these polymer films to their intended surface could be inhibited, thereby achieving film growth in the proximal uninhibited area. Two methods of polymer functionalization were evaluated: phosphonic acid groups distributed randomly throughout the polymer backbone of PVC and a single phosphonic acid group localized at the chain end of PS. Notably, the PVC multidentate derivatives and the PS monodentate type polymers exhibited effective inhibition of TiO2. Published by the AVS.
