Thiamine-Mediated Cooperation Between Auxotrophic Rhodococcus ruber ZM07 and Escherichia coli K12 Drives Efficient Tetrahydrofuran Degradation

Tetrahydrofuran (THF) is a universal solvent widely used in the synthesis of chemicals and pharmaceuticals. As a refractory organic contaminant, it can only be degraded by a small group of microbes. In this study, a thiamine auxotrophic THF-degrading bacterium, Rhodococcus ruber ZM07, was isolated from an enrichment culture H-1. It was cocultured with Escherichia coli K12 (which cannot degrade THF but can produce thiamine) and/or Escherichia coli K12 Delta thiE (which can neither degrade THF nor produce thiamine) with or without exogenous thiamine. This study aims to understand the interaction mechanisms between ZM07 and K12. We found that K12 accounted for 30% of the total when cocultured and transferred with ZM07 in thiamine-free systems; in addition, in the three-strain (ZM07, K12, and K12 Delta thiE) cocultured system without thiamine, K12 Delta thiE disappeared in the 8th transfer, while K12 could still stably exist (the relative abundance remained at approximately 30%). The growth of K12 was significantly inhibited in the thiamine-rich system. Its proportion was almost below 4% after the fourth transfer in both the two-strain (ZM07 and K12) and three-strain (ZM07, K12, and K12 Delta thiE) systems; K12 Delta thiE’s percentage was higher than K12’s in the three-strain (ZM07, K12, and K12 Delta thiE) cocultured system with exogenous thiamine, and both represented only a small proportion (less than 1% by the fourth transfer). The results of the coculture of K12 and K12 Delta thiE in thiamine-free medium indicated that intraspecific competition between them may be one of the main reasons for the extinction of K12 Delta thiE in the three-strain (ZM07, K12, and K12 Delta thiE) system without exogenous thiamine. Furthermore, we found that ZM07 could cooperate with K12 through extracellular metabolites exchanges without physical contact. This study provides novel insight into how microbes cooperate and compete with one another during THF degradation.

Non-porous organic crystals and their interaction with guest molecules from the gas phase

Some organic molecules encapsulate solvents upon crystallization. One class of compounds that shows a high propensity to form such crystalline solvates are tetraaryladamantanes (TAAs). Recently, tetrakis(dialkoxyphenyl)-adamantanes have been shown to encapsulate a wide range of guest molecules in their crystals, and to stabilize the guest molecules against undesired reactions. The term ‘encapsulating organic crystals’ (EnOCs) has been coined for these species. In this work, we studied the behavior of three TAAs upon exposition to different guest molecules by means of sorption technique. We firstly measured the vapor adsorption/desorption isotherms with water, tetrahydrofuran and toluene, and secondly, we studied the uptake of methane on dry and wet TAAs. Uptake of methane beyond one molar equivalent was detected for wet crystals, even though the materials showed a lack of porosity. Thus far, such behavior, which we ascribe to methane hydrate formation, had been described for porous non-crystalline materials or crystals with detectable porosity, not for non-porous organic crystals. Our results show that TAA crystals have interesting properties beyond the formation of conventional solvates. Gas-containing organic crystals may find application as reservoirs for gases that are difficult to encapsulate or are slow to form crystalline hydrates in the absence of a host compound.

An electrode-level prelithiation of SiO anodes with organolithium compounds for lithium-ion batteries

Silicon monoxide (SiO) is considered an attractive alternative to conventional graphite anodes due to its high specific capacity and good cycling performance. However, it suffers from low initial Coulombic efficiency (ICE) due to a large irreversible capacity and large volume change during cycling. Both deficiencies hinder the commercial use of SiO anodes. A new organolithium compound (Li-9,9-dimethyl-9H-fluorene-tetrahydrofuran) with lower redox potential is reported to prelithiate a SiO-based anode. An SEI layer is formed during prelithiation and a controllable amount of reversible lithium is preloaded into the SiO electrode. The ICE of a prelithiated SiO-based electrode in half-cell format is increased greatly to similar to 90.7%. When matched with a LiNi0.6Co0.2Mn0.2O2 cathode, the full cell with the prelithiated SiO/G anode exhibits a much improved ICE in comparison with the pristine one (87.1% vs. 61.1%). This facile prelithiation method is proved to be a practical solution for the commercial application of SiO-based materials.

Bromelain Immobilized onto Diamine-functionalized Electrospun Polyvinyl Chloride Fibers as a Durable Heterogeneous Catalyst

The best condition to produce smooth polyvinyl chloride (PVC, M.W. similar to 6.4×10(4) g/mol) fibers (572 +/- 171 nm) was 10 % w/v PVC in a mixture of tetrahydrofuran and dimethyl sulfoxide (4:1 by volume) with 5 % w/w Tween 20, 15 kV, 10 cm, and 3 ml/h. PVC fibers were subjected to plasma surface treatment to make them more hydrophilic. Diameters of the treated fibers were 549 +/- 99 nm. Next, the PVC fibers were treated with ethylene diamine (EDA) and p-phenylenediamine (PDA) to obtain PVC-EDA and PVC-PDA, respectively. Bromelain was immobilized onto PVC-EDA and PVC-PDA by an aid of 1 % w/v glutaraldehyde to receive PVC-EDA-bromelain and PVC-PDA-bromelain with good tensile strengths of similar to 19 and similar to 14 MPa, respectively. The activities of free and immobilized bromelain were assayed by casein as a substrate and a spectrophotometer at 275 nm. Bromelain loadings on PVC-EDA-bromelain and PVC-PDA-bromelain were 88.10 +/- 3.54 and 36.38 +/- 18.10 mg/g of fibers, respectively. The kinetic activities of bromelain, PVC-EDA-bromelain, and PVC-PDA-bromelain were 11.31 +/- 2.17, 0.31 +/- 0.03, and 2.15 +/- 1.34 min(-1), respectively. PVC-EDA-bromelain and PVC-PDA-bromelain could be reused at least 9 times with > 50 % relative activities and endured heat (50-90 degrees C) better than free bromelain did. Their relative activities were > 70 % after storage at 90 degrees C for 20 min.

Solvent-Mediated Synthesis of Amorphous Li3PS4/Polyethylene Oxide Composite Solid Electrolytes with High Li+ Conductivity

Solvent-mediated routes have emerged as an effective, scalable, and low-temperature method to fabricate sulfide-based solid-state electrolytes. However, tuning the synthesis conditions to optimize the electrolyte’s morphology, structure, and electrochemical properties is still underexplored. Here, we report a new class of composite solid electrolytes (SEs) containing amorphous Li3PS4 synthesized in situ with a poly(ethylene oxide) (PEO) binder using a one-pot, solvent-mediated route. The solvent and thermal processing conditions have a dramatic impact on the Li(3)P(S)4 structure. Conducting the synthesis in tetrahydrofuran resulted in crystalline beta-Li3PS4 whereas acetonitrile led to amorphous Li3PS4. Annealing at 140 degrees C increased the Li+ conductivity of an amorphous composite (Li3PS4 + 1 wt % PEO) by 3 orders of magnitude (e.g., from 4.5 x 10(-9) to 8.4 x 10(-6) S/cm at room temperature) because of: (i) removal of coordinated solvent and (ii) rearrangement of the polyanionic network to form P2S74- and PS43- moieties. The PEO content in these composites should be limited to 1-5 wt % to ensure reasonable Li+ conductivity (e.g., up to 1.1 x 10(-4) S/cm at 80 degrees C) while providing enough binder to facilitate scalable processing. The results of this study highlight a new strategy to suppress crystallization in sulfide-based SEs,, which has important implications for solid-state batteries.

Studies of FeSe(2)Cathode Materials for Mg-Li Hybrid Batteries

Rechargeable magnesium (Mg)-based energy storage has attracted extensive attention in electrochemical storage systems with high theoretical energy densities. The Mg metal is earth-abundant and dendrite-free for the anode. However, there is a strong Coulombic interaction between Mg(2+)and host materials that often inhibits solid-state diffusion, resulting in a large polarization and poor electrochemical performances. Herein, we develop a Mg-Li hybrid battery using a Mg-metal anode, an FeSe(2)powder with uniform size and a morphology utilizing a simple solution-phase method as the counter electrode and all-phenyl-complex/tetrahydrofuran (APC)-LiCl dual-ion electrolyte. In the Li+-containing electrolyte, at a current density of 15 mA g(-1), the Mg-Li hybrid battery (MLIB) delivered a satisfying initial discharge capacity of 525 mAh g(-1). Moreover, the capacity was absent in the FeSe2|APC|Mg cell. The working mechanism proposed is the Li+-only intercalation at the FeSe(2)and the Mg(2+)dissolved or deposited at the Mg foil in the FeSe2|Mg2+/Li+|Mg cell. Furthermore, ex situ XRD was used to investigate the structural evolution in different charging and discharging states.

Striking effect of carbon nanotubes on adjusting sc-CO2 foaming performance of PS/LLDPE blends and forming semi-open cellular structure

The effect of carbon nanotubes (CNTs) on the phase structure and foaming performance of PS/LLDPE blends during batch foaming of sc-CO2 was studied. It was found that the phase structure of PS/LLDPE = 50/50 blends with CNTs could be transformed from bi-continuous to sea-island morphology, when a sufficient quantity of CNTs nanofillers was added. As a result, the foaming ability of PS/LLDPE = 50/50 blends was improved effectively. Meanwhile, the critical value of CNTs for significantly improving the foaming ability of blends decreased slightly with the increase of foaming temperature. In contrast, for the PS/LLDPE blends with sea-island phase structure (such as 20/80), the addition of CNTs did not significantly change the morphology and foaming capacity of the blends. Very interestingly, the foam with semi-open cellular structure (meaning that there were small pores within the large cell wall) was obtained in the foamed PS/LLDPE blends after tetrahydrofuran (THF) etching PS phase. Benefiting from the interfacial channel effect formed by the presence of CNTs, the etching speed and efficiency of PS were significantly improved, and the size for the small pore on the cell wall could be adjusted by the content of PS dispersed phase in the PS/LLDPE/CNTs nanocomposites.

Design, synthesis, and structure – Activity relationship, molecular modeling, and NMR studies of a series of phenyl alkyl ketones as highly potent and selective phosphodiesterase-4 inhibitors

Phosphodiesterase 4 catalyzes the hydrolysis of cyclic AMP and is a target for the development of anti-inflammatory agents. We have designed and synthesized a series of phenyl alkyl ketones as PDE4 inhibitors. Among them, 13 compounds were identified as having submicromolar IC50 values. The most potent compounds have IC50 values of in the mid- to low-nanomolar range. Compound 5v also showed preference for PDE4 with selectivity of >2000-fold over PDE7, PDE9, PDE2, and PDE5. Docking of 5v, 5zf, and 5za into the binding pocket of the PDE4 catalytic domain revealed a similar binding profile to PDE4 with rolipram except that the fluorine atoms of the difluoromethyl groups of 5v, 5za, and 5zf are within a reasonable range for hydrogen bond formation with the amide hydrogen of Thr 333 and the long alkyl chain bears additional van der Waals interactions with His 160, Asp 318, and Tyr 159.
