Published: July 2018

Silica nanoparticles were obtained during the work according to two different sol–gel methods. In first one Schtrober's technique and series of cobalt phthalocyanine metal complexes varying in peripheral substituents were used. Second method was performed using the same complexes but differed in applying surface‐active substance (SAS) and two precursors – tetraethoxysilane (TEOS) and aminopropyltrimethoxysilane (APTMOS). All obtained hybrid materials were analyzed via SEM, the size of single particle was studied, which in all cases was about 200 nm. In order to investigate hybrid's characteristics laser diffraction and liquid nitrogen adsorption methods were applied. Distinction in pore's specific volume of differently‐obtained nanoparticles was found. Catalytic activity of all obtained materials were tested in conversion of N,N‐diethylcarbamodithiolate to thiuram E. Effect of peripherally substituted phthalocyanines and morphology of matrixes were manifested on catalytic activity of the hybrids.

Published: July 2018

AbstractThis article sustains that competitive advantages can be developed when industries implement corporate environmental responsibility (CER) programs systematically and strategically, as demonstrated by data provided by a case study conducted with maquiladora industries in Ciudad Juárez, on the Mexico–United States border. In that study, organizational theory and studies were combined with qualitative analytical techniques to explore relationships between environmental management programs and competitive advantage indicators such as innovation, corporate image, and cost reduction. The data were collected from semistructured interviews with managers of environmental issues and from the official documents of seven regional maquiladoras. The findings showed a direct relationship between implementation of CER programs and activities with the resulting evolution of competitive advantages. Further analysis shows that it is the systematic and strategic implementation of CER programs as part of an overall managerial strategy that allows for the generation of competitive advantages through the mediation of innovation as a key factor.

AbstractPro‐environmental consumption is necessary for sustainable development, but the sales of eco‐friendly products have been limited. In this regard, the present study analyses the failure factors of eco‐friendly product consumption activation from the consumer's perspective, specifically focusing on detergent‐free washing machines, which are representative innovative products of eco‐friendly home appliances. This study analyses: (1) the attitude‐behaviour gap that occurs in the consumer decision‐making process, and (2) the consumer preference with respect to the core attributes. A recursive model considering the decision‐making stage was constructed and a mixed logit model was utilized to analyse the preference for the core attributes. As a result, the product compatibility and transfer of expert information must be secured to reduce the attitude‐behaviour gap. Additionally, washing power is an important attribute for improving product saleability. The analysis framework of this study can be used to establish sustainable policies for activating eco‐friendly products.
The influence of carbon cost pass through on the link between carbon emission and corporate financial performance in the context of the European Union Emission Trading Scheme
Authors: Brouwers Roel , Schoubben Frederiek , Van Hulle Cynthia 
Published: July 2018

AbstractIn this study we examine, within the context of the European Union Emission Trading Scheme, whether firms' ability to pass through carbon costs affects the link between carbon emission and corporate financial performance. Our results, controlling for the endogenous relationship between carbon emission and financial performance, and robust to a number of alternative financial performance measures, demonstrate that good carbon emission performance does not always pay off. In fact, we find that lower levels of carbon emission are only rewarded if firms are not able to pass on carbon costs to consumers, either due to industry characteristics or firm‐specific carbon efficiency. Our results are in line with the view that as pollution is associated with increasing environmental costs, this negative impact of pollution on financial performance is mitigated for “carbon cost pass through” firms.

Published: July 2018

AbstractMicroRNAs (miRNAs) participate in the development and progression of melanoma. However, while dysregulation of microRNA‐378 (miR‐378) has been seen in various cancer types, its clinical importance and function in melanoma are poorly elucidated. In this work, miR‐378 expression in melanoma and in adjacent non‐cancerous tissue was evaluated with a quantitative real‐time polymerase chain reaction. A series of assays (wound healing, Transwell, and nude mouse subcutaneous tumor model) were used to investigate the implications of abnormal miR‐378 regulation on melanoma cell migration and invasion in vitro, and on tumorigenicity in vivo. Prediction and conformation of the miR‐378 target gene was undertaken using bioinformatic analysis and luciferase reporter system. Expression of miR‐378 was often increased in melanoma, and shown to potentiate its migration, invasion, and tumorigenicity. miR‐378 acted, at least partially, through inhibition of the potential target FOXN3 and via Wnt/β‐catenin pathway activation. The findings indicate that miR‐378 triggers melanoma development and progression. This miRNA could be a novel diagnostic and prognostic biological marker and provide utility for targeted treatment of melanoma.
A Density Functional Theory Study of the Mechanism of Direct Glucose Dehydration to 5‐Hydroxymethylfurfural on Anatase Titania
Authors: Li Guanna , Pidko Evgeny A. , Hensen Emiel J. M. , Nakajima Kiyotaka 
Published: July 2018

AbstractA new mechanism for glucose dehydration to HMF without the intermediate isomerization to fructose is discussed for surface models of anatase TiO2 using periodic density functional theory calculations. Activation of the glucose at glucose's C3‐OH position by titania starts the reaction resulting in adsorbed 3‐deoxyglucosone. The mechanistic study reveals two possible pathways for the acyclic form of glucose. Comparison of different surface models shows that the presence of tetrahedral Ti4+ species on a defective TiO2(101) anatase surface is essential for explaining the activity. Synergy between a strong Lewis acidic Ti site and a vicinal basic oxygen site of a TiOH group is essential to establish the direct conversion of glucose to HMF. IR spectroscopy of adsorbed chloroform in the presence of water confirms the presence of water tolerant Lewis acid sites in close proximity to basic sites. In conventional glucose dehydration, Lewis acid sites and proton donors act as catalytic sites for efficient sequential isomerization‐dehydration to HMF, while direct dehydration to HMF requires the cooperation of Lewis acid‐base pairs.

AbstractWater electrolysis provides an efficient method to produce hydrogen as clean energy source. Developing high activity electro‐catalysts towards the oxygen evolution reaction (OER) is crucial to improve the energy‐conversion efficiency of water electrolysis. In this work, heterogeneous nanostructures of NiFe hydroxide composites decorated by Ni metal were directly grown on a porous nickel foam (NF) substrate through an ultrafast electrodeposition process at a large cathodic current density of 1.5 A cm−2 within only 2 seconds. The as‐prepared Ni/NiFe (OH)x–1500 electrode offers a low OER overpotential of 240 mV at 10 mA cm−2 and 290 mV at 100 mA cm−2, a small Tafel slope of 36 mV Dec−1, which are superior to those of a commercial RuO2/Ti electrode. Moreover, Ni/NiFe (OH)x–1500 shows good stability and low cell voltage in the long‐time alkaline‐water splitting. Additionally, the Ni/NiFe (OH)x–1500 electrode also displays excellent electro‐catalytic activity toward the oxidation of hydrazine and glucose. This work provides a facile and rapid method to obtain high performance multifunctional electro‐catalysts.

Pancake Bonding: An Unusual Pi‐Stacking Interaction
Authors: Kertesz Miklos 
Published: July 2018

AbstractA category of parallel π‐stacking interaction, termed pancake bonding, is surveyed. The main characteristics are: the interaction occurs among radicals with highly delocalized π‐electrons in their singly occupied molecular orbitals (SOMOs), the contact distances in the π‐stacking direction are shorter than the typical van der Waals distances, and the stabilization obtained by the bonding combination of the SOMO orbitals leads to direct atom‐to‐atom overlap with strong orientational preferences. These atypical intermolecular interactions contain a component of electron sharing between the radicals that can be viewed as covalent‐like. Pancake bonded dimers characteristically have low‐lying singlet and triplet states and show characteristic interlayer vibrational modes. Pancake bonded aggregates serve as molecular components in many conducting and other functional organic materials. The role of van der Waals (vdW) interactions in pancake bonded dimers, chains, and other aggregates is different from closed shell vdW aggregates: here the Pauli repulsions reduce the attractive dispersion interaction significantly. Fluxionality between π‐ and σ‐bonded aggregates often occur in the context of pancake bonding. Both experimental and computational aspects are reviewed.
The Deep Sea Osmolyte TrimethylamineN‐Oxide and Macromolecular Crowders Rescue the Antiparallel Conformation of the Human Telomeric G‐Quadruplex from Urea and Pressure Stress

Published: July 2018

AbstractOrganisms are thriving in the deep sea at pressures up to the 1 kbar level, which imposes severe stress on the conformational dynamics and stability of their biomolecules. The impact of osmolytes and macromolecular crowders, mimicking intracellular conditions, on the effect of pressure on the conformational dynamics of a human telomeric G‐quadruplex (G4) DNA is explored in this study employing single‐molecule Förster resonance energy transfer (FRET) experiments. In neat buffer, pressurization favors the parallel/hybrid state of the G4‐DNA over the antiparallel conformation at ≈400 bar, finally leading to unfolding beyond 1000 bar. High‐pressure NMR data support these findings. The folded topological conformers have different solvent accessible surface areas and cavity volumes, leading to different volumetric properties and hence pressure stabilities. The deep‐sea osmolyte trimethylamineN‐oxide (TMAO) and macromolecular crowding agents are able to effectively rescue the G4‐DNA from unfolding in the whole pressure range encountered on Earth.

Published: July 2018

AbstractAlpine deciduous shrubs play an important role in local water cycle for ecosystems of Qinghai‐Tibet Plateau, but rainfall partitioning of the deciduous shrubs has not been fully understood due to significant variation in spatial coverage and leaf storage capacity, especially the lack of appropriate model to describe relevant processes. To assess these processes, field experiments were performed to determine vegetation and atmospheric parameters for the deciduous Potentilla fruticosa shrub in the growing season of 2012. Based on the experimental data, a variable parameters Gash model specifically for deciduous shrub rainfall partitioning was adapted from the revised Gash model to simulate rainfall partitioning. Results showed that the interception, throughfall, and stemflow accounted for 21.44%, 29.26%, and 49.30% of total rainfall in the shrub patches, respectively. Nearly half of interception (46.1%) was lost through evaporation from saturated leaf canopy during rainfall events. The performance of the original model on deciduous shrub canopy was improved by utilizing a variable parameters Gash model that adopted event‐based changeable meteorological and canopy parameters. The rainfall partitioning pattern in the shrub patch was very sensitive to changes in canopy coverage, evaporation, and rainfall intensity, in which great varieties can add large potential errors to the revised Gash model simulations. To accurately model rainfall partitioning, it is reasonable to adopt variable parameters.
Soil water dynamics at 15 locations distributed across a desert landscape: insights from a 27‐yr dataset

Published: July 2018

AbstractDesert ecosystems are primarily limited by water availability. Within a climatic regime, topography, soil characteristics, and vegetation are expected to determine how the combined effects of precipitation, temperature, and evaporative demand of the atmosphere shape the spatial and temporal patterns of water within the soil profile and across a landscape. To forecast how desert landscapes may respond to future climatic conditions, it is imperative to improve our understanding of these ecohydrologic processes. Here, we report on 27 yr of monthly soil volumetric water content (VWC) measurements and associated soils data from a site in the northern Chihuahuan Desert of North America. The dataset includes VWC and soil properties measured to 3 m in depth across 15 locations that encompass a range of Chihuahuan Desert vegetation types. We use this unique dataset (1) to generate insights into general temporal and depth patterns in VWC, (2) to analyze how VWC corresponds to measures of climatic conditions, and (3) to qualitatively evaluate the relative importance of soils, topographic setting, and vegetation type in mediating temporal patterns in VWC. Analyses of this unique dataset emphasize the importance of soil and topographic setting in determining depth and temporal patterns in VWC across time. Results emphasize the episodic nature of deep wetting events in our study system—essentially limited to three large events over the 27‐yr record driven primarily by wetter than normal winters. Comparison of soil water dynamics between mesquite shrub coppice dunes and interspace soils suggests the “island of fertility” concept does not extend to soil water. Median VWC was strongly coupled to climatic conditions over surprisingly long windows at most locations (6–18 months), suggesting that soil water at depth is decoupled from short climatic pulses. However, VWC dynamics and VWC–climate relationships varied among locations, depths, and seasons, with unexpected similarities in ecohydrologic dynamics observed among very different vegetation types (e.g., an eroded creosote shrubland and a playa grassland). These results further underscore the importance of ecohydrological investigations in these ecosystems, given forecasts for a warmer and more variable climate in deserts globally.
Testing the addictive appetite model of binge eating: The importance of craving, coping, and reward enhancement

Published: July 2018

AbstractIn the current study, we examine components of the “addictive appetite” model of recurrent binge eating. Specifically, we tested the influence of addictive processes and the influence of emotional regulation processes on recurrent binge eating behaviour. We recruited 79 women in total for the current study: 22 with bulimia nervosa, 26 weight‐matched lean comparison women, 15 women with binge eating disorder, and 16 weight‐matched overweight/obese comparison women. Participants completed questionnaire assessments of food craving and motivations for eating. Compared with weight‐matched comparison women, women with binge‐type eating disorders endorse significantly greater levels of food craving, eating for purposes of coping, and eating for purposes of reward enhancement. A cluster analysis revealed that these three traits distinguish women with binge‐type eating disorders from weight‐matched comparison women. These findings provide support for the addictive appetite model of binge eating behaviour and highlight addictive and emotional regulation processes as potential targets for treatment.
Wind influence on the orientation of estuarine landforms: An example from Lake Illawarra in southeastern Australia
Authors: Deng Junjie , Jones Brian G. , Rogers Kerrylee , Woodroffe Colin D. 
Published: July 2018

AbstractWe propose a type of a quasi‐equilibrium, which describes a convergence of the estuarine system towards a form whose planimetric orientation is along the prevailing winds. By using the microtidal Lake Illawarra in southeastern Australia as an example, we describe sediment convergent and divergent processes that induce such an equilibrium controlled by the complex configuration of the shoreline relative to the prevailing winds. For a complex estuarine sedimentary system with a mixture of non‐cohesive and cohesive sediments, alongshore distribution of fluvial or marine sand deposition and associated subaqueous morphology reflects alongshore redistribution of sediments from rivers and the tidal inlet. The orientation of the second‐order polynomial trend surface of estuarine morphology is consistent with prevailing wind directions. Along the lake shore, there are extensive narrow flats mainly covered by fluvial or marine sands shaped by the prevailing winds. The implementation of the Delft3D flow model coupled with the SWAN wave model driven by idealized prevailing winds indicates the potential of sediment convergent and divergent transport at the embayment and promontory shoreline, which appears to be similar to the alongshore distribution of sandy sediments and the nearshore flats. Alongshore transport of sandy sediments is primarily induced by the wave refraction on the shore, while the currents are more effective in transporting fine‐grained sediments such as mud or clay. Finally, we suggest a conceptual model that describes potential sediment transport of convergence and divergence on the embayment or promontory shoreline that is normal to the prevailing winds. Orientation of the estuary follows the convergence centre of sediment transport driven by the prevailing winds with the largest fetch. A quantitative threshold for such sediment redistribution may be determined in the future. © 2018 John Wiley & Sons, Ltd.
Decomposing parasite fitness reveals the basis of specialization in a two-host, two-parasite system

Published: July 2018

AbstractThe ecological specialization of parasites–whether they can obtain high fitness on very few or very many different host species–is a determining feature of their ecology. In order to properly assess specialization, it is imperative to measure parasite fitness across host species; to understand its origins, fitness must be decomposed into the underlying traits. Despite the omnipresence of parasites with multiple hosts, very few studies assess and decompose their specialization in this way. To bridge this gap, we quantified the infectivity, virulence, and transmission rate of two parasites, the horizontally transmitted microsporidians Anostracospora rigaudi and Enterocytospora artemiae, in their natural hosts, the brine shrimp Artemia parthenogenetica and Artemia franciscana. Our results demonstrate that each parasite performs well on one of the two host species (A. rigaudi on A. parthenogenetica, and E. artemiae on A. franciscana), and poorly on the other. This partial specialization is driven by high infectivity and transmission rates in the preferred host, and is associated with maladaptive virulence and large costs of resistance in the other. Our study represents a rare empirical contribution to the study of parasite evolution in multihost systems, highlighting the negative effects of under- and overexploitation when adapting to multiple hosts.
