Effects of aridity in controlling the magnitude of runoff and erosion after wildfire
Authors: Noske Philip J. , Nyman Petter , Lane Patrick N. J. , Sheridan Gary J.
Published: May 2016

This study represents a uniquely high‐resolution observation of postwildfire runoff and erosion from dry forested uplands of SE Australia. We monitored runoff and sediment load, and temporal changes in soil surface properties from two (0.2–0.3 ha) dry forested catchments burned during the 2009 Black Saturday wildfire. Event‐based surface runoff to rainfall ratios approached 0.45 during the first year postwildfire, compared to reported values <0.01 for less arid hillslopes. Extremely high runoff ratios in these dry forests were attributed to wildfire‐induced soil water repellency and inherently low hydraulic conductivity. Mean ponded hydraulic conductivity ranged from 3 to 29 mm h−1, much lower than values commonly reported for wetter forest. Annual sediment yields peaked at 10 t ha−1 during the first year before declining dramatically to background levels, suggesting high‐magnitude erosion processes may become limited by sediment availability on hillslopes. Small differences in aridity between equatorial and polar‐facing catchments produced substantial differences in surface runoff and erosion, most likely due to higher infiltration and surface roughness on polar‐facing slopes. In summary, the results show that postwildfire erosion processes in Eucalypt forests in south‐east Australia are highly variable and that distinctive response domains within the region exist between different forest types, therefore regional generalizations are problematic. The large differences in erosion processes with relatively small changes in aridity have large implications for predicting hydrologic‐driven geomorphic changes, land degradation, and water contamination through erosion after wildfire across the landscape.
Crustal structure and extension mode in the northwestern margin of the South China Sea
Authors: Gao Jinwei , Wu Shiguo , McIntosh Kirk , Mi Lijun , Liu Zheng , Spence George
Published: May 2016

Combining multi‐channel seismic reflection and gravity modeling, this study has investigated the crustal structure of the northwestern South China Sea margin. These data constrain a hyper‐extended crustal area bounded by basin‐bounding faults corresponding to an aborted rift below the Xisha Trough with a subparallel fossil ridge in the adjacent Northwest Sub‐basin. The thinnest crust is located in the Xisha Trough, where it is remnant lower crust with a thickness of less than 3 km. Gravity modeling also revealed a hyper‐extended crust across the Xisha Trough. The postrift magmatism is well developed and more active in the Xisha Trough and farther southeast than on the northwestern continental margin of the South China Sea; and the magmatic intrusion/extrusion was relatively active during the rifting of Xisha Trough and the Northwest Sub‐basin. A narrow continent‐ocean transition zone with a width of ∼65 km bounded seaward by a volcanic buried seamount is characterized by crustal thinning, rift depression, low gravity anomaly and the termination of the break‐up unconformity seismic reflection. The aborted rift near the continental margin means that there may be no obvious detachment fault like that in the Iberia‐Newfoundland type margin. The symmetric rift, extreme hyper‐extended continental crust and hotter mantle materials indicate that continental crust underwent stretching phase (pure‐shear deformation), thinning phase and breakup followed by onset of seafloor spreading and the mantle‐lithosphere may break up before crustal‐necking in the northwestern South China Sea margin.
Dust devil dynamics

Published: May 2016

A self‐consistent hydrodynamic model for the solar heating‐driven onset of a dust devil vortex is derived and analyzed. The toroidal flows and vertical velocity fields are driven by an instability that arises from the inversion of the mass density stratification produced by solar heating of the sandy surface soil. The nonlinear dynamics in the primary temperature gradient‐driven vertical airflows drives a secondary toroidal vortex flow through a parametric interaction in the nonlinear structures. While an external tangential shear flow may initiate energy transfer to the toroidal vortex flow, the nonlinear interactions dominate the transfer of vertical‐radial flows into a fast toroidal flow. This secondary flow has a vertical vorticity, while the primary thermal gradient‐driven flow produces the toroidal vorticity. Simulations for the complex nonlinear structure are carried out with the passive convection of sand as test particles. Triboelectric charging modeling of the dust is used to estimate the charging of the sand particles. Parameters for a Dust Devil laboratory experiment are proposed considering various working gases and dust particle parameters. The nonlinear dynamics of the toroidal flow driven by the temperature gradient is of generic interest for both neutral gases and plasmas.
Real‐Time PEGDA‐Based Microgel Generation and Encapsulation in Microdroplets
Authors: Martino Chiara , Vigolo Daniele , Solvas Xavier Casadevall i , Stavrakis Stavros , deMello Andrew J.
Published: May 2016

Herein, a method is reported that combines droplet‐based microfluidics and microscope projection photolithography for the generation of poly ethylene glycol diacrylate microgels and their encapsulation within pL‐volume droplets. By implementing continuous‐flow photolithography in the vicinity of a cross junction, the real‐time generation and in situ encapsulation of fiber‐like structures within pL‐volume aqueous microdroplets is demonstrated. The effect of UV excitation is assessed at varying distances from the cross junction for both constant and pulsed UV excitation modes, as a route to controlling microfiber length. Finally, UV excitation within trapped droplets is explored and how the combination of the two techniques can lead to the generation of 3D patterned microstructures is demonstrated, opening new avenues for the rapid generation of inner scaffolding of artificial cell facsimiles.
Au/TS‐1 catalyst for propene epoxidation with H2/O2: A novel strategy to enhance stability by tuning charging sequence
Authors: Feng Xiang , Liu Yibin , Li Yichuan , Yang Chaohe , Zhang Zhihua , Duan Xuezhi , Zhou Xinggui , Chen De
Published: May 2016

For propene epoxidation with H2 and O2, the catalytic performance of Au/TS‐1 catalyst is extremely sensitive to preparation parameters of deposition‐precipitation (DP) method. In this work, effect of charging sequence in DP process on catalyst structure and catalytic performance of Au/TS‐1 catalyst is first investigated. For different charging sequences, the compositions of Au complexes (e.g., [AuCl(OH)3]−) and pore property of TS‐1 (i.e., with or without H2O prefilling micropores) could affect the transfer of Au complexes into the micropores, resulting in different Au locations and thus significantly different catalytic performance. Notably, when TS‐1 is first filled with H2O and then mixed with Au complexes, the reduced Au/TS‐1 catalyst could expose Au nanoparticles on the external surface of TS‐1 and show high stability. The results provide direct evidence showing that micropore blocking is the deactivation mechanism. Based on the results, a simple strategy to design highly stable Au/Ti‐based catalysts is developed. © 2016 American Institute of Chemical Engineers AIChE J, 62: 3963–3972, 2016
Production and Purification of Recombinant Proteins from Escherichia coli
Authors: Tripathi Nagesh K.
Published: May 2016

Development of successful production strategies for recombinant proteins is a challenging task due to problems associated with the scale‐up of bioprocesses. Recent developments in fermentation technology have provided a suitable platform to produce bioproducts for the development of diagnostics, therapeutics and vaccines for bacterial, viral and other diseases. A bacterial system is the commonly used expression system for production of recombinant products such as proteins, enzymes, and antibodies. Escherichia coli is one of the most commonly used bacterial hosts for the production of these products. A variety of recombinant proteins has been produced and cultivation studies have been carried out at small scale. However, the majority of the recombinant proteins are not amenable directly to large scale production processes due to various factors. To meet the growing demand of potential bioproducts, there is a need to produce these products in large quantity employing fermentation processes. Development of a suitable purification strategy is yet another important step to recover biologically active products. The present paper reviews the current developments in production and purification of recombinant products from E. coli. The bioproducts obtained after fermentation and purification processes may fulfill the requirements for the development of various diagnostics, therapeutics, or prophylactic agents against different kinds of diseases.

Published: May 2016

A template‐assisted polymer‐derived ceramic route is investigated for preparing a series of silicoboron carbonitride (Si/B/C/N) foams with a hierarchical pore size distribution and tailorable interconnected porosity. A boron‐modified polycarbosilazane was selected to impregnate monolithic silica and carbonaceous templates and form after pyrolysis and template removal Si/B/C/N foams. By changing the hard template nature and controlling the quantity of polymer to be impregnated, controlled micropore/macropore distributions with mesoscopic cell windows are generated. Specific surface areas from 29 to 239 m2 g−1 and porosities from 51 to 77 % are achieved. These foams combine a low density with a thermal insulation and a relatively good thermostructural stability. Their particular structure allowed the in situ growth of metal–organic frameworks (MOFs) directly within the open‐cell structure. MOFs offered a microporosity feature to the resulting Si/B/C/N@MOF composite foams that allowed increasing the specific surface area to provide CO2 uptake of 2.2 %.
2,4‐Dinitrophenol‐Catalyzed α‐C(sp3)−H and C(sp)−H Bond Functionalization of Cyclic Amines and Alkynes: Highly Regio‐/Diastereoselective Synthesis of α‐Alkynyl‐3‐Amino‐2‐Oxindoles
Authors: Kumar Mukesh , Kaur Banni P. , Chimni Swapandeep S
Published: May 2016

A transition‐metal‐ and oxidant‐free DNP (2,4‐dinitrophenol)‐catalyzed atom‐economical regio‐ and diastereoselective synthesis of monofunctionalized α‐alkynyl‐3‐amino‐2‐oxindole derivatives by C−H bond functionalization of cyclic amines and alkynes with indoline‐2,3‐diones has been developed. This cascade event sequentially involves the reductive amination of indoline‐2,3‐dione by imine formation and cross coupling between C(sp3)−H and C(sp)−H of the cyclic amines and alkynes. This reaction offers an efficient and attractive pathway to different types of α‐alkynyl‐3‐amino‐2‐oxindole derivatives in good yields with a wide tolerance of functional groups. The salient feature of this methodology is that it completely suppresses the homocoupling of alkynes. To the best of our knowledge, this is the first example of a DNP‐catalyzed metal‐free direct C(sp3)−H and C(sp)−H bond functionalization providing biologically active α‐alkynyl‐3‐amino‐2‐oxindole scaffolds.

Published: May 2016

Parallel, tetramolecular G‐quadruplex (G4) DNA possessing TINA monomer, (R)‐1‐O‐[4‐(1‐pyrenylethynyl)phenylmethyl]glycerol, were synthesised and evaluated in complexes with tris(2,2′‐bipyridine)ruthenium(II), [Ru(bpy)3]2+, and the Zn2+ derivative of 5,10,15,20‐tetrakis‐(1‐methyl‐4‐pyridyl)‐21 H,23H‐porphine, ZnTMpyP4. UV/Vis, fluorescence, and circular dichroism (CD) spectroscopy showed that the use of G4‐DNA as a template resulted in the effective communication between the ligands and the TINA molecule that was covalently attached to the 5′‐end and between T and dG at the 5′‐end of the dTG4T sequence. Only one G4‐DNA possessing the TINA molecule at the 5′‐end of the dTG4T sequence was able to yield a green‐to‐blue photochemical upconversion (PUC, λem=420 nm) in the presence of [Ru(bpy)3]2+ upon excitation at 500 nm. Different DNA secondary structures can thus be used in DNA‐based assemblies for PUC and the way of attachment of chromophores to DNA plays a pivotal role for the creation of a photosynthetic centre.
