Synthesis and Coordination Behavior of a New Hybrid Bidentate Ligand with Phosphine and Silylene Donors

This work describes the synthesis and coordination behavior of a new mixed-donor ligand PhC(NtBu)(2)SiC6H4PPh2 (1) containing both silylene and phosphine donor sites. Ligand 1 was synthesized from a reaction of ortho-lithiated diphenylphosphinobenzene (LiC6H4PPh2) with chlorosilylene (PhC(NtBu)(2)SiCl). Treatment of 1 with Se and GeCl2 resulted in Si-IV compounds 2 and 3 by selective oxidation of the silylene donor. This strong sigma-donor ligand induces dissociation of CuCl and PhBCl2 leading to formation of ionic complexes 4 and 5 respectively. The reaction of 1 with ZnCl2 and AlCl3 resulted in the formation of chelate complexes 5 and 7, respectively, while treatment with EtAlCl2 and GaCl3 forms monodentate complexes 8 and 9. X-ray analysis of 4 showed that the copper is in the spiro center of the two five-membered rings. Moreover, the copper(I)chloride has not been oxidized but dissociates to Cu+ and [CuCl2](-). All the compounds are well characterized by mass spectrometry, elemental analysis, NMR spectroscopy, and single-crystal X-ray diffraction studies.

Establishment of Pediatric Reference Intervals for Routine Laboratory Tests in Korean Population: A Retrospective Multicenter Analysis

Background: Reference intervals defined for adults or children of other ethnicities cannot be applied in the evaluation of Korean pediatric patients. Pediatric reference intervals are difficult to establish because children are in their growing stage and their physiology changes continuously. We aimed to establish reference intervals for routine laboratory tests for Korean pediatric patients through retrospective multicenter data analysis. Methods: Preoperative laboratory test results from 1,031 pediatric patients aged 0 month-18 years who underwent minor surgeries in four university hospitals were collected. Age- and sex-specific reference intervals for routine laboratory tests were defined based on the Clinical and Laboratory Standards Institute (CLSI) EP28-A3c guidelines. Results: The pediatric reference intervals determined in this study were different from existing adult reference intervals and pediatric reference intervals for other ethnicities. Most tests required age-specific partitioning, and some of those required sex-specific partitioning for at least one age-partitioned subgroup. Erythrocyte sedimentation rate, monocyte percentage, basophil percentage, activated partial thromboplastin time, glucose, cholesterol, albumin, bilirubin, chloride, and C-reactive protein did not show any difference between age- or sex-partitioned subgroups. Conclusions: We determined Korean pediatric reference intervals for hematology, coagulation, and chemistry tests by indirect sampling based on medical record data from multiple institutions. These reference intervals would be valuable for clinical evaluations in the Korean pediatric population.

Synthesis, characterization and desalination study of polyvinyl chloride-co-vinyl acetate/cellulose acetate membranes integrated with surface modified zeolites

Novel mixed matrix membranes of polyvinyl chloride-co-vinyl acetate/cellulose acetate (PVCA/CA) infused with nano-particles of both pristine zeolite (p-zeolite) and 3-aminopropyl triethoxysilane (APTS) functionalized zeolite (f-zeolite) were synthesized by dissolution casting method for desalination application. MMMs were then characterized using FTIR, SEM, contact angle and DMA analysis. FTIR and TGA analysis were also carried out for zeolite particles to confirm the surface functionalization. The loading effect of zeolite (1, 3 and 5 wt. %) and the impact of APTS functionalization on dispersion, morphological structure, thermo-mechanical properties and hydmphilicity were also analyzed. Desalination performance of the membranes was evaluated using 2000 ppm NaCl solution at 6 bar pressure. SEM analysis demonstrated that APTS functionalization improved the uniformity of the zeolite nano-particles in the membrane and a noticeable reduction in undesirable microscopic voids. Higher hydmphilicity was attained with the inclusion of f-zeolite nanoparticles, as confirmed by contact angle measurement analysis. It was found that the membrane infused with 5 wt. % of f-zeolite exhibited substantial improvements in storage modulus, glass transition temperature and cross-link density. Membranes infused with f-zeolite demonstrated enhanced transport mechanism without showing trade-off between water flux and salt rejection. In particular, inclusion of 5 wt. % f-zeolite, resulted in achieving the highest salt rejection of 99.56% with water flux increment of -24% in comparison to the neat PVCA/CA membrane. Finally, the membranes were tested for anti-fouling properties using flux recovery ratio test. Thus, the newly developed PVCA/CA membranes embedded with APTS f-zeolite can be exploited for high performance desalination applications.

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.

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.

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.

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.

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.

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.

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.
