Abstract
In optoelectronics, inkjet printing (IJP) technology is being developed as an alternative to the traditional techniques for organic materials deposition. In this work, we report the fabrication of organic light-emitting diodes (OLEDs) on the flexible substrate by studying the effect of a surface chemical treatment on the inkjet printed polymer film morphology. The employed piranha treatment increases the substrate surface energy and improves the wettability, thus inducing a decrease in the IJ printed drop thickness. The IJ printed polymer (poly(9,9-dihexyl-9H-fluorene-2,7-diyl)) is the hole-transporting layer (HTL) of a hybrid structure in which the other layers are deposited by vacuum thermal evaporation. Furthermore, in order to determine the effect of the IJ deposition method on the manufactured OLED performances, we compare them to those of devices fabricated using standard technologies. With this aim, OLEDs with the same structure are fabricated by replacing the IJ printed polymer with a spin-coated film employing the same polymer solution. The electrical and optical properties of the electroluminescent devices are investigated and discussed. Despite the lack of thickness uniformity in IJ printed film, which is an intrinsic, technological limit, OLEDs with IJ printed HTL show electro-optical characteristics that are similar to the ones of OLEDs with spin-coated HTL.

Abstract
Tunable dichromic electroluminescence is obtained from a blend of Eu3+ complex in polyfluorene by a single spin-coatable emitting layer device with external quantum efficiency as high as 1%, the highest reported in literature to our knowledge. The design of a complex whose ligand increases the site isolation of Eu3+ ion allows reduction of the back-transfer quenching effects that prevented up to now the multicolor electroluminescence of Eu3+ complex/polyfluorene blends. Energy transfer mechanisms involving singlet and triplet excitons are analyzed by focusing on the effects of site isolation and polarity of the new ligand that provide homogeneous dispersion of the complex in the conjugated polymer.

Abstract
We present a study of the photophysical (absorption and emission) and thermal stability properties of zinc bis(8-quinolinolato) (Znq2), lithium mono(8-quinolinolato) (Liq) chelates, and their methylated derivatives. These materials are compared with aluminum tris(8-quinolinolato) (Alq3), which has proven to be viable for use in organic light-emitting devices (OLED's). We show that regardless of metal ion substitution the effect of ligand methylation on the photophysical and thermal properties is similar for all Mqn materials. However, strong solvent dependence of absorption, emission and 1H NMR chemical shifts for zinc and lithium chelates support a stronger ionic character of the metal-ligand bonding, which may have significant effects on electroluminescent properties.

Abstract
Electroluminescent materials comprising quinoxaline, triarylamine, and

fluorophores such as carbazole, pyrene, and fluorene were prepared by using a key step involving a Pd-catalyzed CN coupling reaction. Chromophores were embedded both at quinoxaline and triarylamine units, and their influence on photophysical and thermal properties was investigated. Quinoxalines possessing more electron-donating amines exhibit lower fluorescence quantum efficiency and the photoluminescence (PL) is severely affected by the polarity of the solvent used for measurement. Bulky and rigid aromatic groups such as pyrene and carbazole enhance the glass transition temperature of the derivatives. Oxidation potential of the triarylamine was easily tuned by the aromatic substituents while retaining the reduction potential of the quinoxaline segment. This provides us a method for tuning the photophysical and thermal properties maintaining the energy levels of the dipolar compounds. The electroluminescent devices fabricated using these materials as hole-transporters and emitters led to intense light emission. The emission color is green and corresponds well with the film PL of the material used.

Abstract
The herbicide glyphosate (N-phosphonomethylglycine) interacts strongly with many soil components. It forms strong complexes with many metals in solution, and it is adsorbed through innersphere complexation to iron- and aluminium oxides.

Glyphosate can also be adsorbed by clay minerals by forming complexes with interlayer cations. Because of these interactions, glyphosate is strongly adsorbed in soils. It is mainly the phosphonic acid moiety that participates in the adsorption, and therefore phosphate competes with glyphosate for adsorption sites. 译文: 译文

草甘膦
除草剂草甘膦(正-膦羧甲基甘氨酸)与许多土壤成分有强烈的相互作用. 它在土壤中能够与许多金属形成配合物, 并且通过内部球形络合作用被铁和铝的 氧化物吸收. 草甘膦也可以通过与间层阳离子形成络合物从而被黏土矿物质所吸 收.由于这些相互作用,草甘膦强烈地吸附在土壤中.因为主要是磷酸部分参与 吸附作用,所以磷肥化合物会与草甘膦竞争吸附作用点.

Abstract
Sorption may affect the bioavailability and biodegradation of pesticides in soils. The aim of this study was to test the effect of surface sorption on microbial utilization of the herbicide glyphosate as a source of phosphorus, nitrogen, or carbon. We added goethite to a humus soil to manipulate the soil's glyphosate sorption capacity. The addition of glyphosate generally either decreased microbial CO2 production or produced no effect. Additions of glyphosate, in combination with glucose and N, did not change the respiration rate in comparison with the same treatment but without glyphosate. In contrast, glyphosate additions combined with glucose and P decreased microbial growth, whereas the combination with goethite counteracted the negative effect. The different treatments were examined using attenuated total reflectance Fourier transform (ATRFTIR) spectroscopy; the results suggest that glyphosate was de-carboxylated in the sorbed state. Stimulating microbial growth by the addition of glucose and nitrogen resulted in further oxidation of glyphosate and only phosphate was detectable on the goethite surface after 13 days incubation. Our results show that sorbed glyphosate is microbially degradable, and it retards microbial activity. This study emphasizes the importance of combining quantitative measurements with a molecular-level examination, to better understand biogeochemical processes. 译文: 译文:
