Assessment of the potential of a reduced dose of dimethyl disulfide plus metham sodium on soilborne pests and cucumber growth

Methyl bromide (MB), a dominant ozone-depleting substance, is scheduled to be completely phased out for soil fumigation by December 30th 2018, in China. The combined effects of dimethyl disulfide (DMDS) plus metham sodium (MNa) were assessed in controlling soilborne pests for soil fumigation. A study was designed in laboratory for the evaluation of the efficacy of DMDS + MNa to control major soilborne pests. At the same time, two trials were conducted in cucumber field located in Tongzhou (in 2012) and Shunyi (in 2013), respectively, in order to assess the potential of DMDS + MNa in controlling soilborne pests. Laboratory studies disclosed positive synergistic effects of almost all four used combinations on Meloidogyne spp., Fusarium spp., Phytophthora spp., Abutilon theophrasti and Digitaria sanguinalis. Field trials found that DMDS + MNa (30 + 21 g a. i. m(-2)), both at a 50% reduced dose, effectively suppressed Meloidogyne spp. with a low root galling index (2.1% and 11.7%), significantly reduced the levels of Phytophthora and Fusarium spp. with a low root disease index (7.5% and 15.8%), gave very high cucumber yields (6.75 kg m(-2) and 10.03 kg m(-2)), and increased income for cucumber growers with the highest economic benefits (20.91 (sic) m(-2) and 23.58 (sic) m(-2)). The combination treatment provided similar results as MB standard dose treatment (40 g a. i. m-2) or DMDS standard dose treatment (60 g a. i. m(-2)) in pest control and yield, but was more effective than MNa standard dose treatment (42 g a. i. m(-2)). Usage of all chemical treatments gave better significant results than the untreated group of control. Considering the economic benefits, the DMDS plus MNa combination (30 + 21 g a. i. m(-2)) could be used for soil fumigation in cucumber production in China.

Structure and Optical Properties of Layered Perovskite (MA)(2)PbI2-xBrx(SCN)(2) (0 <= x < 1.6) The layered perovskite (MA)(2)PbI2(SCN)(2) (MA = CH3NH3+) is a member of an emerging series of compounds derived from hybrid organic-inorganic perovskites. Here, we successfully synthesized (MA)(2)PbI2-xBrx(SCN)(2) (0 <= x < 1.6) by using a solid-state reaction. Despite smaller bromide substitution for iodine, 1% linear expansion along the a axis was observed at x similar to 0.4 due to a change of the orientation of the SCN- anions. Diffuse reflectance spectra reveal that the optical band gap increases by the bromide substitution, which is supported by the DFT calculations. Curiously, bromine-rich compounds where x >= 0.8 are light sensitive, leading to partial decomposition after similar to 24 h. This study demonstrates that the layered perovskite (MA)(2)PbI2(SCN)(2) tolerates a wide range of bromide substitution toward tuning the band gap energy.

Simultaneous fabrication of carbon nanodots and hydroxyapatite nanoparticles from fish scale for biomedical applications

Fish industries and markets produce large quantities of fish scales, skins, shells, and bone wastes post processing that contaminate the environment and cause health risks in humans. In this context, we have developed a novel and simple integrated process to valorize the Lethrinus lentjan fish scales by fabricate carbon nanodots (CDs) and hydroxyapatite nanoparticles (HA NPs) simultaneously. The fish scale treatment was carried out by hydrothermal method at 280 degrees C that produced CDs and HA NPs simultaneously. Under hydrothermal treatment, organic and inorganic substances of fish scale is transformed to CDs and HA NPs respectively. As TEM images confirmed that fish scale derived CDs were spherically shaped and similar to 3 to 15 nm in size. The CDs exhibited excitation-dependent emission in photoluminescence. The HA NPs were similar to 8 to 12 nm in diameter and similar to 50 to 100 nm in length with rod shape. Also, HA NPs possess spherical shape nanostructures with 15-50 nm in diameter. Furthermore, we assessed the cytotoxic behavior of synthesized nanostructures using the MTT assay and acridine orange/ethidium bromide (AO/EB) staining. These results showed that synthesized CDs and HA NPs did not cause significant changes in cell viability and morphology, indicating biocompatibility. Additionally, the synthesized CDs and HA NPs were exploited as fluorescent probes for cellular imaging and osteogenic differentiation of stem cells respectively. Overall, the study results indicate that low-cost fish waste was valorized by producing CDs and HA NPs concurrently. The synthesized nanostructures can be applicable for bio-imaging and bone tissue engineering applications.

Synthesis of Enantiomerically Enriched Alkynylaryl-Substituted alpha-Amino Acids through Sonogashira Reactions

Various enantiomerically enriched non-proteinogenic (S)-alpha-amino acids were obtained in high chemical and optical yields through Sonogashira cross-coupling reactions and Glaser couplings. The Schiff base Ni(II)complexes of the chiral auxiliary (S)-BPB (BPB = N-benzyl proline benzophenone) and an amino acid containing an aryl bromide moiety in the alpha-position were synthesized and subsequently used in Sonogashira coupling reactions. The obtained Ni(II) complexes were hydrolyzed with aqueous HCl and novel amino acids, containing an alkynylaryl moiety, were isolated in good yields and with high enantiomeric excess (>99% ee). The chiral auxiliary (S)-BPB can be recycled and reused for the synthesis of the starting Ni(II) complex.

Direct catalytic transformation of white phosphorus into arylphosphines and phosphonium salts

Phosphorus compounds are ubiquitous in the chemical sciences, finding applications throughout industry and academia. Of particular interest to synthetic chemists are organophosphorus compounds, which contain P-C bonds. However, state-of-the-art processes for the synthesis of these important materials rely on an inefficient, stepwise methodology involving an initial oxidation of white phosphorus (P-4) with hazardous chlorine gas and the subsequent displacement of chloride ions. Catalytic P-4 organofunctionalization reactions have remained elusive, as they require multiple P-P bond-breaking and P-C bond-forming events to break down the P-4 core, all of which must occur in a controlled manner. Herein, we describe an efficient transition-metal-catalysed process capable of forming P-C bonds from P-4. Using blue-light photocatalysis, this method directly affords valuable triarylphosphines and tetraarylphosphonium salts in a single reaction step.

Enhanced toughness and strength of boron carbide ceramics with reduced graphene oxide fabricated by hot pressing

Boron carbide (B4C) hybrids with different contents of graphene oxide (GO) were prepared by a heterogeneous co-precipitation method using cetyltrimethyl ammonium bromide (CTAB) as the cationic surfactant. The asobtained mixtures were further hot-pressed at 1950 degrees C for 60 min under 30 MPa, by which B4C-reduced GO (rGO) composites were fabricated. It was found that the addition of only 0.5 wt% rGO could alter the predominance of trans-granular fracture in monolithic B4C ceramic material to mixed trans-granular and intergranular modes in B4C-rGO composites. The flexural strength and fracture toughness of the B4C-2 wt% rGO were increased by 31% (from 350 to 455 MPa) and 83% (from 3.20 to 5.85 MPa.m(1/2)), respectively, compared with those of pure B4C. The improved mechanical properties are attributed to the mechanisms of pull-out and bridging of rGO and crack deflection, as evidenced by microstructural observations. The energy dissipation in the present B4C-rGO composites was further verified using two micromechanical models.

Activating ATRP Initiators to Incorporate End-Group Modularity into Photo-RAFT Polymerization

Heterogeneous photocatalysis is increasingly used in reversible deactivation radical polymerization (RDRP). In this study, we found that alkyl bromide redox chemistry typically found in atom transfer radical polymerization (ATRP) can be incorporated in concert with dithiocarbonyl disulfide chemistry into the reversible addition-fragmentation chain transfer (RAFT) process via bismuth oxide photocatalysis. This amalgamation of mechanisms introduces end-group modularity-a new layer of control-into RAFT polymers uniquely enabled by photoredox catalysis. We found that a diversity of functionality can be installed at the alpha-end group via alkyl bromides, while the molecular weight distribution can be tuned seamlessly at the omega-end group through the simultaneous addition of multiple disulfides.
