Reaction of (GaClPc)-Cl-III, (SnCl2TPP)-Cl-IV and B(III)ClSubPc with cyanide anions: reduction of macrocycles vs. formation of cyano-containing macrocyclic anions

The reaction of (GaClPc)-Cl-III, (SnCl2TPP)-Cl-IV and B(III)ClSubPc containing phthalocyanine (Pc), tetraphenylporphyrin (TPP) and subphthalocyanine (SubPc) macrocycles with cyanide in the presence of cryptand[2.2.2] under anaerobic conditions yields crystalline salts in which cyano anions substitute chloride anions at Ga-III, Sn-IV or B-III, as well as reducing the macrocycles or adding one or two CN- to them. The reaction of (GaCl)-Cl-III(Pc2-) with CN- yields {crypt(K+)}{(GaCN)-C-III(Pc3-)}(-)center dot 0.5C(6)H(4)Cl(2) (1) in which the Pc2- macrocycle is reduced to Pc3-. Such reduction could probably occur through the addition of CN- to Pc2- forming {Ga-III(CN)[Pc(CN)](3-)}(-) which can decompose further interacting with an excess of CN-. As a result, Pc3- and cyanogene anions are formed. The interaction of (SnCl2)-Cl-IV(TPP2-) with CN- is accompanied by the addition of CN- to the meso-carbon atom of porphyrin forming diamagnetic TPP(CN)(3-) macrocycles in {crypt(K+)}{Sn-IV(CN)(2)[TPP(CN)](3-)}(-) (2). Salt 2 shows a strong NIR absorption band with the maximum at 854 nm whose intensity is comparable with that of the Soret band. The interaction of (BCl)-Cl-III(SubPc(2-)) with three equivalents of CN- is accompanied by the addition of two CN- to carbon atoms of SubPc(2-) closest to meso-nitrogen atoms forming {B-III(CN)[SubPc(CN)(2)](4-)}(2-). Most probably these dianions transfer electrons to C6H4Cl2 producing the {B-III(CN)[SubPc(CN)(2)](3-)}(-) radical anions which form sigma-bonded diamagnetic dianions in {crypt(K+)}(2){B-III(CN)[SubPc(CN)(2)]}(2)(2-)center dot 3C(6)H(4)Cl(2) (3). The remaining carbon atom closest to the meso-nitrogen atom is involved in this dimerization. According to the calculations, the energy of the C-CN bond is minimal for {Ga-III(CN)[Pc(CN)](3-)}(-) enabling further transformation of these anions to {(GaCN)-C-III(Pc3-)}(-) in 1, whereas cyano-containing anions in 2 and 3 with higher energy of this bond are stable towards the elimination of CN. Optical and magnetic properties of 1-3 together with their crystal and molecular structures are presented. The possible ways of the formation of 1-3 are discussed based on DFT calculations.

Formation of gamma-aminobutyric acid (GABA) during the natural lactic acid fermentation of cucumber

This study investigated gamma-aminobutyric acid (GABA) formation during natural lactic acid fermentation of cucumbers. Two lots of cucumbers were fermented or acidified in duplicate in 4 % sodium chloride (NaCl) brine and analyzed for GABA content over 6 months storage. GABA was present in fresh and acidified pickling cucumbers at 0.83 +/- 0.16 mM and 0.56 +/- 0.30 mM, respectively. Additional GABA was generated in fermented cucumbers (1.21 +/- 0.35 mM) and remained stable over time and during further processing. Brine salt content (2 % 6 %) affected GABA formation with greatest GABA formation in cucumber brined in 2 % NaCl (1.38 +/- 0.31 mM). Commercially available, fermented cucumber pickles packed in their original fermentation brines contained more GABA (1.32 +/- 0.25 mM) than acidified (0.46 +/- 0.26 mM) or fermented, desalted and re-packed products (0.49 +/- 0.32 mM). This work demonstrated that low-salt fermentation enhances GABA content in fermented cucumber products prepared for direct consumption.

A corrosion study on W-Cu alloys in sodium chloride solution at different pH

A corrosion study of two types of tungsten-copper (W-Cu) alloys in 3.38 wt.% NaCl solution with different pH at 25 degrees C were investigated using potentiodynamic polarization and immersion test. It is crucial that the corrosion behavior and preferential attacked phases of the W-Cu alloys were found to alter with pH. The micro-galvanic effect of tungsten phase and copper binder played a significant role. It was also proved that the existence of aggressive chloride ions could accelerate the Cu binder dissolution in acidic and neutral solution, which induced tungsten phase detachment and increased the corrosion rate of the W-Cu alloys. While Cl- would accelerate the Cu binder dissolution of W-Cu alloys at high potential during polarization test in strong alkaline solution.

Processing of fast neutron reactor fuel by electrorefining: Thematic overview

This work provides basic knowledge on the spent fuel management on the basis of the published literature data on electrorefining. This review examines three main areas of work devoted to electrorefining. These are electrodeposition and electrodissolution using solid and liquid electrodes, as well as mass transfer in phases present during electrorefining. As part of this research, the composition of the irradiated metallic fuel was estimated. Due to the great potential difference between solid cathodes, it is possible to separate actinides from lanthanides. The co-deposition of metallic Pu and U in the eutectic LiCl-KCl melt containing UCl3 and PuCl3 indicates stable co-precipitation of U and Pu at U3+ concentration less than similar to 0.2 wt. Periodically performed electrical transport of ions to liquid (Cd) and solid cathodes in the galvanic mode made it possible to deposit preferentially U on the solid cathode, and Pu and Am on the liquid cathode. Oxidation of these metals caused fluctuations in the anode potential. The electrode processing after electrorefining is investigated. This process consists of oxidizing the actinides remaining in the liquid electrode by adding CdCl2 and removing the associated chloride by high-temperature distillation. During the electrorefining of irradiated metallic fuel, the fission products accumulate in the molten salt. Reduction of uranium on a solid cathode from a spent molten salt using a liquid Cd-Li anode is considered. A model that describes electrorefining with a liquid metal anode, solid cathode, and molten LiCl-KCl salts, is presented. The formation of plutonium at the surface of a solid cathode is analyzed. In a one-dimensional model of an electrorefiner, it is shown that the concentration of Pu at the cathode cannot be predicted from the Cm concentration in the melt.

Cadmium exposure induces inflammation through the canonical NF-kappa B pathway in monocytes/macrophages of Channa punctatus Bloch

A vast range of research related to the toxicity of the heavy metal cadmium (Cd) has been carried out in a wide variety of fish species. However, Cd induced immunomodulation in monocytes/macrophages of Channa punctatus Bloch. has rarely been explored. The present study was designed to determine Cd induced immune response, role of NF-kappa B (nuclear factor kappa B) pathway and the subsequent downstream molecular responses in monocytes/macrophages of C. punctatus. Fish were sampled and acclimatized, with one group treated with cadmium chloride (CdCl2) (1.96 mg/L) and another kept as untreated control group, both under observation for 7 days. Exposure to CdCl2 was found to alter hematological profile of C. punctatus in addition to incurring histo-architectural damages in the HK (head kidney) and ultrastructural changes in the monocytes/macrophages. The innate immune potential was found to be significantly compromised as evident from decreased phagocytosis, intracellular killing, cell adhesion and reduced release of nitric oxide (NO) and myeloperoxidase (MPO) in Cd intoxicated group. Also Cd triggered ROS generation, reduced cellular NO levels by forming peroxynitrite along with the upregulated expression of the inflammatory marker iNOS (inducible nitric oxide synthase) in monocytes/macrophages, both at mRNA and protein levels, indicating inflammation. Inflammation is further verified from the upregulated expression of proinflammatory cytokines viz. TNF-alpha, IL-1 beta, IL-6, IL-12 along with a central inflammatory mediator NF-kappa B and downregulation of the anti-inflammatory cytokine IL-10, both at mRNA and protein levels. It can be concluded that, a sub-lethal exposure of Cd in C. punctatus for 7 days caused significant alterations in the hematological, histological and ultrastructural profile in monocytes/macrophages; impaired innate immune parameters, triggers ROS generation and inflammation as validated from the upregulated expression of NF-kappa B, iNOS, TNF-alpha, IL-1 beta, IL-6, IL-12 and IL-10 downregulation.

Polyvinyl chloride/quaternized poly phenylene oxide substrates supported thin-film composite membranes: Enhancement of forward osmosis performance

Quaternized poly phenylene oxide (QPPO) was synthesised and used as a modifier material to blend with polyvinyl chloride (PVC) to cast the substrate for thin-film composite (TFC) forward osmosis (FO) membranes. The addition of QPPO improved the porosity, hydrophilicity, and morphology of the substrate, thereby weakening the internal concentration polarisation of TFC membranes. Furthermore, the introduction of QPPO improved the structure of the active layer, which led to higher water permeability. Moreover, the mechanical properties of the TFC membranes were significantly improved after the introduction of QPPO. As a result, introducing QPPO significantly increased the FO performance. In addition, the TFC membrane based on a 40% QPPO blend ratio exhibited optimal FO performance: a high water flux of 71.21 L h(-1) m(-2) and an extremely low specific reverse solute flux of 0.079 g L-1 under the active layer facing the draw solution (DS) mode by utilising 1 M NaCl as the DS and deionised (DI) water as the feed solution; this FO performance remained fairly stable during long-term operation. This study suggests that introducing QPPO into the substrate is a sensible strategy for fabricating high-performance TFC FO membranes.

Exploiting Deep Eutectic Solvents and Ionic Liquids for the Valorization of Chestnut Shell Waste

The full utilization of agricultural waste and its recycle into a new chain of value are of primary importance for the development of a sustainable and profitable agricultural industry. Chestnut shell waste (CSW) is an interesting case of study, whose valorization has been though partially investigated to date. This work aims at exploring the complete utilization of CSW, in terms of obtaining both value-added compounds and enriched cellulose and lignin fractions. The results were obtained via the unreported combined use of two classes of nonconventional organic solvents, namely natural deep eutectic solvents and bio-based ionic liquids (bio-ILs). At first, combinations of choline chloride (ChCl)-based DESs with an acid, a polyol, or a sugar as hydrogen bond donors were employed for the extraction of polyphenols from the CSW. The best performing system was found to be ChCl:oxalic acid dihydrate (ChCl:Oax2H(2)O). The extraction efficiencies of the DESs tested correlate well with the measured Kamlet-Taft a parameters. After polyphenol removal, the residual solid material was treated with a bio-IL [cholinium glycinate (ChGly)] for further separation of lignin and cellulose. The products obtained by the fractionation process were characterized by Fourier transform infrared spectroscopy and thermogravimetric analysis, which confirmed the separation of the residue into a lignin-rich material and a cellulose-rich material. The results obtained were further corroborated by a three parallel reaction model combined with the distributed activation energy model, which allowed for predicting the composition of the pristine CSW and of the ChCl:Oax2H(2)O treated CSW as well as the two fractions obtained after ChGly treatment. The recyclability of the best performing DES and the recovery of the bio-IL have also been proven, which make the whole process viable and amenable for large-scale applications.

Evolution of magnetic properties of crystalline cobalt-iron boride nanoparticles via optimization of synthesis conditions using hydrous metal chlorides

Chemical synthesis of crystalline and nanoscale cobalt-iron metal boride powders was studied using hydrous metal chlorides and NaBH4. The effects of precursor concentration and optimized synthesis conditions on the phase formation, microstructure, and magnetic properties were investigated. After applying a reaction of CoCl2 center dot 6H(2)O-FeCl3 center dot 6H(2)O-NaBH4 at 850 degrees C, (CoFe)B-2, (CoFe)B, Co2B, Fe3B, and Fe0.71Co0.29 boride phases were obtained from different synthesis conditions applied under autogenic pressure or Ar flow atmosphere. Oxychloride impurities were the reason for the reduced magnetization values. The highest saturation magnetization of 183 emu/g belongs to obtained nanoparticles containing (CoFe)B-2 and (CoFe)B pure phases. High temperature magnetic measurements marked synthesized powders as soft magnetic materials up to 795 K while no T-c was reached for the obtained phases.

In situ measurement of sludge thickness in high-centrifugal force by optimized particle resistance normalization for wireless electrical resistance detector (WERD)

This study investigates the in situ sludge thickness of polymers in a real-scale horizontal decanter centrifuge using the optimized particle resistance normalization (OPRN) technique. The sludge thickness of poly(methyl methacrylate) (PMMA) in an aqueous sodium chloride (NaCl) carrier fluid was observed as a function of the normalized particle resistance of a wireless electrical resistance detector. The measured resistance of the continuous phase during the centrifugation is set as the reference and normalized following its dominant frequency by Fourier transform. Here, the OPRN limits the particle resistance using the normalization function based on the closed-packing condition (i.e. Krieger 1972 Adv. Colloid Interface Sci. 3 111-36; Phillips et al 1992 Phys. Fluids A 4 30-40; and Rao et al 2002 Int. J. Numer. Methods Fluids. 39 465-83) in the particle sensitivity area (PSA). The normalized value is then plotted in the fitting equation using a nonlinear generalized reduced gradient. The PSA is solved by a simulation study on electrostatics and by static experiments. Two different centrifugation parameters of feed rates and two centrifugal forces at four different measurement points were considered to observe the sludge thickness distribution as a function of operational time. As a result, the in situ sludge thickness is described in the nonlinear fit plot equation with a coefficient score to explain the separation phenomenon inside the decanter centrifuge. The plot agrees well with the experimental data with a high degree of coefficient of determination.

Fabrication and characterization of entirely inkjet-printed polysilicon thin film transistors

In this paper, the fabrication and material innovation involved in the first and only entirely inkjet-printed polysilicon thin film transistors (TFTs) are described. To form TFT layers, five inkjet printing inks were developed with the goal of fabricating TFTs by using purely additive processing without vacuum deposition or conventional lithography. A silicon ink was developed to form both the channels and polysilicon gates, and boron and phosphorus dopant inks were developed for N+ and P+ doping. In addition, a silver nanoparticle (NP) ink was developed to form interconnect traces, and a palladium chloride ink was formulated to create palladium silicide for the ohmic contacts between the source and the drain. The first N-type metal-oxide-semiconductor (MOS) polysilicon TFT was fabricated with a top-gate self-alignment scheme. This exhibited a mobility of approximately 80 cm(2) V s(-1). Next, P-type MOS transistors as well as complementary MOS devices were also successfully fabricated.
