Selective separation of copper (II) and cobalt (II) from wastewater by using continuous cross‐flow micellar‐enhanced ultrafiltration and surfactant recovery from metal micellar solutions
Authors: Anthati Vijay Anand Kumar , Marathe K. V. 
Published: August 2010

AbstractPerformance of continuous cross‐flow micellar‐enhanced ultrafiltration (MEUF) method was investigated for the selective separation of copper (Cu2+) and cobalt (Co2+) from the aqueous phase using sodium dodecyl sulfate (SDS) as an anionic surfactant and iminodiacetic acid (IDA) as a chelating agent. Operating parameters such as operating time (10–120 min), cross‐flow rate (100–250 mL/min), pH of the solution (2.8–5.6), molar concentration ratio of the chelating agent to metals (the C/M ratio, 0.5–2.5), molar concentration ratio of the surfactant to metals (the S/M ratio, 5–8) and mode of operation were studied to investigate the effectiveness of the process on selective separation. At optimal parameters, above 90% selective separation (Cu2+ in permeate and Co2+ in retentate) was achieved. Two methods were studied for the separation of Co2+ and SDS from retentate stream; acidification followed by UF and addition of chelating agent followed by UF with surfactant recovery of 75% and 83%, respectively, and Co going into the permeate.
Direct measurement of groundwater uptake through tree roots in a cave
Authors: Doody Tanya M. , Benyon Richard G. 
Published: August 2010

AbstractRecent intensive research investigating groundwater extraction of Pinus radiata D. Don plantations in south east South Australia has focused on measurement of sapflow rates in P. radiata stems above ground. An extended dry period in summer 2001 provided an opportunity to install sapflow sensors in a P. radiata root clump, which extended through a limestone cave to an unconfined aquifer approximately 14 m below the surface. Over 5 days in March 2001, sapflow velocities were monitored in three individual roots extending from a 58‐year‐old P. radiata tree. A second sensor set installed in the tree stem enabled direct comparison of water flow through the tree stem and roots. Sap‐flux density averaged 0·840 m3 m−2 day−1 and 0·240 m3 m−2 day−1, in the roots and stem, respectively. Sapwood cross‐sectional area of the root clump was 0·012 m2 compared to 0·193 m2 for the main tree stem. Total water flow through the stem over 5 days, averaged 0·046 m3 day−1 compared to 0·010 m3 day−1 through the root clump. Thus, at least 22% of tree water use came directly from the unconfined aquifer via these roots. The tree was possibly obtaining more than 22% of its water from this source, if additional tree roots had aquifer access. These results present direct evidence that P. radiata trees can extract water from an unconfined aquifer at depth, if their roots are able to reach the watertable, providing direct support to intensive water balance studies in the region that infer groundwater extraction.

Observation of Room‐Temperature Deep‐Red/Near‐IR Phosphorescence of Pyrene with Cycloplatinated Complexes: An Experimental and Theoretical Study
Authors: Wu Wenting , Wu Wanhua , Ji Shaomin , Guo Huimin , Zhao Jianzhang 
Published: August 2010

AbstractPyrene‐containing cyclometallated PtII complexes, with the pyrene moiety directly cyclometallated (Pt‐1) or connected to a 2‐phenylpyridine (ppy) ligand through a C–C (Pt‐2) or C≡C bond (Pt‐3), and a control complex with a phenyl group attached to the ppy ligand (Pt‐4) have been prepared. Room‐temperature deep‐red/near‐IR (NIR) phosphorescence emission (650–800 nm) was observed for Pt‐1, Pt‐2 and Pt‐3, whereas Pt‐4 showed emission at 528 nm. We found that Pt‐2, in which the pyrene moiety is not directly cyclometallated, shows intense pyrene‐based phosphorescence, which contrasts with a previous report that direct cyclometallation is necessary for the observation of the phosphorescence of pyrene in cyclometallated complexes. Besides the phosphorescence emission in the deep‐red/near‐IR range, a fluorescence emission band at higher energy was observed. Thus, these complexes can be described as unichromophore multi‐emissive materials. Normal 3MLCT/3IL emission at 528 nm was observed for Pt‐4. The UV/Vis absorption and phosphorescence emissions of the complexes were rationalized by DFT/TDDFT calculations. Theoretical calculations propose pyrene‐localized T1 states (3IL) for Pt‐1, Pt‐2 and Pt‐3, which is supported by the experimental results. The complexes were used in luminescent O2‐sensing experiments. These studies will be helpful in the development of room‐temperature phosphorescent materials and their application as luminescent molecular sensing or electroluminescent materials are promising.
Cell Compatible Fluorescent Chemosensor for Hg2+ with High Sensitivity and Selectivity Based on the Rhodamine Fluorophore
Authors: Jiang Li , Wang Ling , Zhang Bo , Yin Gui , Wang Rui‐Yong 
Published: August 2010

AbstractAn easily prepared “turn‐on”‐type fluorescent chemosensor for mercury based on Rhodamine‐B, which exhibits high sensitivity and selectivity over other metal ions in aqueous systems, was obtained. The distinctive wavelengths in the UV/Vis absorption range can sense Hg2+, Cu2+, and Fe3+ separately. Furthermore, this “turn‐on”‐type fluorescent sensor, upon the addition of Hg2+ over other competitive species, was successfully applied to bioimaging in yeast and HeLa cells. The potential of these types of chemosensors for use in environmental and biological systems is great.
Self‐Organization by Chiral Recognition Based on ad hoc Chiral Pockets in Cyclotriphosphazenes with Binaphthoxy and Biphenoxy Substituents: An X‐ray, NMR and Computational Study

Published: August 2010

AbstractThe chiral cyclic triphosphazenes (R)‐(–)‐[N3P3(O2C20H12)(O2C12H8)Cl2] (I) and (R,R)‐(–) [N3P3(O2C20H12)2(O2C12H8)] (II), prepared by sequential substitution of [N3P­3Cl6] using (R)‐2,2′‐dihydroxy‐1,1′‐binaphthyl, 2,2′‐dihydroxy‐1,1′‐biphenyl and Cs2CO3 in acetone, have been investigated by single‐crystal X‐ray diffraction, variable‐temperature NMR spectroscopy in solution and MM calculations under periodic boundary conditions in the gas state. In both compounds only the diastereomer corresponding to the (R)‐biphenoxy configuration is present in the solid state. In spite of the existence of quite large voids potentially occupied by solvents, the configuration adopted by the biphenoxy substituents is solely determined by packing interactions consisting of definite preferential supramolecular interactions between a biphenoxy group of one molecule and the chiral pocket created between the biphenoxy and binaphthoxy groups of another molecule. A network of T‐shaped non‐covalent interactions ensures an efficient chiral discrimination. The in silico simulations confirmed this hypothesis. Both the concentration‐dependence and temperature‐variable 1H NMR spectra in solution confirmed this behaviour showing that on lowering the temperature one of the two diasteroisomers vanished after conversion into the more stable atropisomer as a consequence of chiral induction of the (R)‐binaphthyl system on the (R)‐biphenyl configuration. In further agreement with the X‐ray structure as well as with the energy distribution resulting from the in silico calculations, the 1H NMR spectra show the dependence of the chemical shift on concentration, which suggests the presence of aggregates in solution. Therefore molecules I and II are capable of a special type of self‐organization by chiral recognition based on the ad hoc generation of chiral pockets.
Palladium‐Catalyzed Bis‐Functionalization of Isatylidenes: A Facile Route towards Spiro‐Indol‐2‐ones

Published: August 2010

AbstractAn effective protocol has been developed for the construction of 3,3‐disubstituted indol‐2‐ones from isatylidenes by utilizing amphiphilic bis‐π‐allylpalladium and related intermediates. The developed strategy is a new method for the quaternization of position 3 of the indol‐2‐one towards disubstituted functionalized indol‐2‐ones. These products were subjected to ring‐closing metathesis towards the synthesis of spiro[cyclohexene‐1,3′‐indol]‐2′‐ones and spiro[oxep‐5‐ene‐2,3′‐indol]‐2′‐ones, which are of biological interest.
Increased “default mode” activity in adolescents prenatally exposed to cocaine

Published: August 2010

AbstractPrenatal cocaine exposure (PCE) is associated with attention/arousal dysregulation and possible inefficiencies in some cognitive functions. However, the neurobiological bases of these teratogenic effects have not been well characterized. Because activities in the default mode network (DMN) reflect intrinsic brain functions that are closely associated with arousal regulation and cognition, alterations in the DMN could underlie cognitive effects related to PCE. With resting‐state and task activation functional magnetic resonance imaging (fMRI), this study investigated the possible PCE related changes in functional brain connectivity and brain activation in the DMN. In the resting state, the PCE group was found to have stronger functional connectivity in the DMN, as compared to the nonexposed controls. During a working memory task with emotional distracters, the PCE group exhibited less deactivation in the DMN and their fMRI signal was more increased by emotional arousal. These data revealed additional neural effects related to PCE, and consistent with previous findings, indicate that PCE may affect behavior and functioning by increasing baseline arousal and altering the excitatory/inhibitory balancing mechanisms involved in cognitive resource allocation.

Relating hydrogeomorphic properties to stream buffering chemistry in the Neversink River watershed, New York State, USA
Authors: Harpold Adrian Adam , Burns Douglas A. , Walter Todd , Shaw Stephen B. , Steenhuis Tammo S. 
Published: August 2010

AbstractMonitoring the effects of acidic deposition on aquatic ecosystems in the Northeastern US has generally required regular measurements of stream buffering chemistry (i.e. acid‐neutralizing capacity (ANC) and calcium Ca2+), which can be expensive and time consuming. The goal of this paper was to develop a simple method for predicting baseflow buffering chemistry based on the hydrogeomorphic properties of ten nested watersheds in the Neversink River basin (2·0–176·0 km2), an acid‐sensitive basin in the Catskill Mountains, New York State. The tributaries and main reach watersheds have strongly contrasting mean baseflow ANC values and Ca2+ concentrations, despite rather homogeneous vegetation, bedrock geology, and soils. A stepwise regression was applied to relate 13 hydrogeomorphic properties to the mean baseflow ANC values and Ca2+ concentrations. The regression analysis showed that watersheds with lower ANC values had a higher mean ratio of ‘quickflow’ runoff to precipitation during 20 non‐snowmelt runoff events (referred to as mean runoff ratio). The mean runoff ratio could explain at least 80% of the variability in mean baseflow ANC values and Ca2+ concentrations among the ten watersheds. Greater mean runoff ratios also correlated with steeper slopes and greater drainage densities, thus allowing the prediction of baseflow ANC values (r2 = 0·75) and Ca2+ concentrations (r2 = 0·77) with widely available spatial data alone. These results indicate that hydrogeomorphic properties can predict a watershed's sensitivity to acid deposition in regions where the spatial sources of stream buffering chemistry from the bedrock mineralogy and soils are fairly uniform.
