Innovation intensity, creativity enhancement, and eco‐innovation strategy: The roles of customer demand and environmental regulation
Authors: Liao Yi‐Chuan , Tsai Kuen‐Hung 
Published: September 2018

AbstractThis study develops a contingency framework to investigate how and when innovation intensity and creativity enhancement affect a firm's eco‐innovation strategy by drawing upon the perspectives of the resource‐based view and stakeholder theory. This investigation aims to explore whether firms with high innovation intensity and creativity enhancement really pursue eco‐innovation strategy. Our examination is based on a sample of 2,126 manufacturing firms. By using a hierarchical regression, the results reveal that the effects of innovation intensity and creativity enhancement on eco‐innovation strategy depend on customer demand and environmental regulation. Specifically, customer demand positively moderates the effects of innovation intensity and creativity enhancement on eco‐innovation strategy, whereas existing regulation has a weaker effect on the relationship between innovation activities and eco‐innovation strategy than that of anticipated regulation.

AbstractA simple, economical successive ionic layer adsorption and reaction (SILAR) method has been used for synthesizing 1, 2 and 3 at.% copper‐doped strontium hydroxide over a stainless‐steel (SS) substrate. X‐ray diffraction reveals the orthorhombic crystal structure of polycrystalline Cu‐doped Sr(OH)2. FTIR and Raman analyses explore the chemical bond analysis of the active material. The morphology of the Cu‐doped Sr(OH)2 was analyzed by using SEM. This shows novel hierarchical‐branched tuberose with flakes. The energy‐dispersive X‐ray spectroscopy (EDAX) also confirms the doping of Cu into Sr(OH)2. The electrochemical properties have been investigated by using cyclic voltammetry (CV) and galvanostatic charge−discharge measurements. It has been perceived that doping clearly affects the supercapacitive behavior. The specific capacity of the 3 at.% Cu‐doped Sr(OH)2 film electrode exhibits a maximum specific capacity of 817 C g−1 at 0.4 mA cm−1 in 1 M Na2SO4 electrolyte, but has a low cycle stability. The 2 at.% Cu‐doped sample shows high cycle stability by retrieving 71 % of its capacity after 5000 cycles. The relationship between the doping concentration and supercapacitive behavior has also been discussed. The good capacitive behavior and cycle stability of the Cu‐doped Sr(OH)2 gives the new perspective for the flexible electrode material, which can be used in the near future as an energy storage material.

AbstractTo enhance energy storage performance via modulation of crystal structure on the molecular level, two series of triethylamine (TEA)‐dependent polyoxometalate (POM) based inorganic‐organic hybrid compounds, [CuII(btx)2]2[SiW12O40] (SiW‐1), [CuI(btx)]4[SiW12O40] (SiW‐2), [CuI4(btx)3][SiW12O40] ⋅ 2H2O (SiW‐3), [{CuII6(btx)7(H2O)12}H4⊂(W12O40)2] ⋅ 12H2O (W‐1), [{CuII7(btx)8(H2O)10}H2⊂(W12O40)2] ⋅ 2H2O (W‐2) and [{CuII10CuI2(btx)11(H2O)16}H2⊂(W12O40)3] ⋅ 6H2O (W‐3) (btx=1,4‐bis(triazol‐1‐ylmethyl)benzene) have been synthesized and explored as pseudocapacitor electrode materials. Compared to other compounds, SiW‐2 shows a specific capacitance of 110.3 F g−1 at 3.0 A g−1 and only experiences a capacitance loss of 13 % after 1000 cycles at a current density of 18.0 A g−1. More importantly, the two series of compounds can be considered as a model for studying the effects of the molecular structures on the pseudocapacitor performance. The result verifies that besides the type of POM, the capacitance ability of the POM‐based compounds is mainly dominated by the connecting modes of adjacent POM building blocks and the dimension of covalent networks formed by POM building blocks. Thus, this work may open a new avenue to optimize the performance of POM‐based capacitors.
Acid‐Regulated Switching of Metal Cation and Anion Guest Binding in Halogen‐Bonding Rotaxanes
Authors: Li Xiaoxiong , Lim Jason Y. C. , Beer Paul D. 
Published: September 2018

AbstractThe ability of natural enzymes to regulate their guest binding affinities and preferences through the use of co‐ligands which alter the features of the binding site is fundamental to biological homeostatic control. Herein, the rarely exploited orthosteric control of guest binding is demonstrated using neutral halogen bonding [2]rotaxanes, in which a chemical stimulus (acid) interacting with the interlocked host binding site switches the host's native guest preference from metal cations to anions. When neutral, the rotaxanes exhibit pronounced transition metal cation affinity and comparatively weak anion binding properties. However, the addition of acid attenuates the rotaxanes’ ability to coordinate cations, while concurrently enabling strong binding of halides through charge assisted halogen bonding and hydrogen bonding interactions in competitive aqueous solvent media. The appendage of a fluorescent anthracene reporter group to the rotaxane framework also enables diagnostic sensory responses to cation/anion binding.

Published: September 2018

AbstractAny cell within a tissue is constantly confronted with a variety of mechanical stimuli. Sensing of these diverse stimuli plays an important role in cellular regulation. Besides shear stress, cells of the vascular endothelium are particularly exposed to a permanent cyclic straining originating from the interplay of outwards pushing blood pressure and inwards acting contraction by smooth musculature. Perpendicular alignment of cells as structural adaptation to this condition is a basic prerequisite in order to withstand deformation forces.Here, we combine live cell approaches with immunocytochemical analyses on single cell level to closely elucidate the mechanisms of cytoskeletal realignment to cyclic strain and consolidate orientation analyses of actin fibres, microtubules (MTs) and vimentin. We could show that strain‐induced reorientation takes place for all cytoskeletal systems. However, all systems are characterized by their own, specific reorientation time course with actin filaments reorienting first followed by MTs and finally vimentin. Interestingly, in all cases, this reorientation was faster than cell body realignment which argues for an active adaptation mechanism for all cytoskeletal systems. Upon actin destabilization, already smallest alterations in actin kinetics massively hamper cell morphology under strain and therefore overall reorientation. Depolymerization of MTs just slightly influences actin reorientation velocity but strongly affects cell body reorientation.
Consumer behavior and corporate social responsibility: An evaluation by a choice experiment
Authors: Boccia Flavio , Malgeri Manzo Rosa , Covino Daniela 
Published: September 2018

AbstractThe relationship between corporate social responsibility and consumer's behavior is more and more strong today: so it influences management of ethical and social effects of companies. The aim of the study is to investigate to what extent the socially responsible behaviors of companies influence consumer purchasing decisions and, moreover, the possible willingness to pay higher prices for good practice products. A choice experiment was conducted in Italy for this purpose on ready‐made foods, where socially responsible initiatives of companies are compared with four levels of price and the presence or absence of a known brand. The analysis shows a positive relationship between socially responsible initiatives of companies and attitudes of consumers towards them and their products. However, by investigation, only few people adopt corporate social responsibility as choice criterion for purchases still, because traditional purchasing criteria continue to prevail, in particular the price. The conclusions are also a matter for thought for further discussion.

AbstractSemiconductor photocatalysis is regarded as an ideal method for use in solving the energy shortage and environmental issues by converting solar energy to chemical energy. Herein, we have designed a facile synthetic methodology to obtain a ternary co‐modified g‐C3N4 composite via WS2 and carbon‐doped TiO2 (C‐TiO2) nanorods with highly efficient photocatalytic activity for hydrogen production from deionized (DI) water and a natural seawater system under visible‐light illumination. This composite exhibits enhanced photocatalytic activity compared to the pristine g‐C3N4, WS2, C‐TiO2 nanorods, and the reference‐modified g‐C3N4 composite with individual WS2 or C‐TiO2 nanorods. Co‐modified g‐C3N4 composite shows a great photostability in both DI water and seawater. Under λ=420 nm monochromatic light illumination, the apparent quantum efficiency of the co‐modified g‐C3N4 composite in seawater solution is 13.08 %, which is higher than pure g‐C3N4 (5.06 %). WS2, TiO2, and g‐C3N4 constitute a ternary heterojunction boosting the fast separation of photoinduced electron–hole pairs, which plays a crucial role in enhancing photocatalytic activity. Therefore, the WS2 and C‐TiO2 nanorod co‐modified g‐C3N4 composite with high photocatalytic performance provides a promising candidate for rationally utilizing the seawater resource to produce clean chemical energy.
Hydrodynamic trait coordination and cost–benefit trade‐offs throughout the isohydric–anisohydric continuum in trees

Published: September 2018

AbstractWhole‐plant hydraulic performance depends on the integrated function of trait complexes, such as embolism resistance, stomatal closure mechanisms, and root properties. The diversity of such traits produces a wide range of response strategies to both short‐term variation of environmental conditions and long‐term changes to climate and hydrological cycles. This study aims to assess the role of different emergent hydraulic trait combinations in trees' vulnerability to drought using a quantitative modelling framework. This modelling framework may be helpful in studying the influence of plant hydraulic traits independently. It will also be used to assess how different groups of traits interact to form viable hydraulic strategies in response to different environmental conditions.We use the advanced plant hydrodynamic model, finite‐difference ecosystem‐scale tree crown hydrodynamics model version 2, to resolve plant functional traits of roots, stems, and leaves and simulate the transpiration. We define a multidimensional hydraulic “strategy space” by considering a continuum of these traits to test the outcomes of different hypothetical strategies in response to environmental conditions as observed in Northern Michigan, USA. We evaluate the degree to which simulated trees suffer hydraulic failure due to cavitation or carbon deficiency in response to reduced stomatal conductance. Our results demonstrate how the relationship between plant hydraulic strategy and hydraulic safety margin emerges from trait combinations along different tissue levels. Our findings suggest that hydrodynamic models present an exciting new possibility to define and study plant traits and hydrodynamics.

AbstractThe cross‐scale resilience model suggests that system‐level ecological resilience emerges from the distribution of species’ functions within and across the spatial and temporal scales of a system. It has provided a quantitative method for calculating the resilience of a given system and so has been a valuable contribution to a largely qualitative field. As it is currently laid out, the model accounts for the spatial and temporal scales at which environmental resources and species are present and the functional roles species play but does not inform us about how much resource is present or how much function is provided. In short, it does not account for abundance in the distribution of species and their functional roles within and across the scales of a system. We detail the ways in which we would expect species’ abundance to be relevant to the cross‐scale resilience model based on the extensive abundance literature in ecology. We also put forward a series of testable hypotheses that would improve our ability to anticipate and quantify how resilience is generated, and how ecosystems will (or will not) buffer recent rapid global changes. This stream of research may provide an improved foundation for the quantitative evaluation of ecological resilience.

Published: September 2018

AbstractBackgroundIt is unknown how familial factors influence the recovery from low back pain (LBP) and the maintenance activity behaviours. We aimed to investigate whether individual and within‐family physical activity (PA) and sedentary behaviour influenced recovery from LBP, and maintenance of PA and sedentary behaviour in people with and without LBP.MethodsLongitudinal logistic regression analyses were performed on adult twins from the Washington State Twin Registry. First, individual and within‐family (based on co‐twin data) sufficient PA (at least 75 min of vigorous‐intensity PA, or 150 min of moderate‐intensity PA per week) and high leisure sitting time (≥3 hr/day) were our exposure variables (baseline). LBP within the past 3 months at follow‐up defined non‐recovery (outcome). Second, within‐family sufficient PA and high leisure sitting time were our exposure variables(baseline) and our outcomes were individual PA and sitting time at follow‐up. All analyses were adjusted for follow‐up length (range: 1–7 years) and confounding variables.ResultsIndividual and within‐family PA and sitting time were not associated with recovery. Within‐family PA and sitting time predicted individual maintenance of PA (OR = 1.47, 95% CI: 1.17–1.84, n = 1,388 twins) and sitting time (OR = 1.41, 95% CI: 1.10–1.82, n = 1,534). Within‐family PA and sitting time had the strongest effects on those without (OR = 1.79, 95% CI: 1.33–2.41, n = 788) and with LBP (OR = 1.90, 95% CI: 1.32–2.76, n = 698), respectively.ConclusionHaving active family members increased the likelihood of continuing to be active (particularly for those without LBP), while having sedentary family members increased the likelihood of maintaining sedentary behaviours (particularly for those with LBP).SignificanceThis study was the first to investigate how familial activity behaviours influence recovery from LBP and ongoing activity behaviours. People with LBP living within a sedentary family likely require specific interventions to reduce their sedentary behaviours.
A design procedure for pin‐supported rocking buckling‐restrained braced frames
Authors: Bosco Melina , Marino Edoardo M. , Rossi Pier Paolo 
Published: September 2018

SummaryThe paper describes a design procedure for a special type of chevron braced frame endowed with ties between the upper ends of the braces of adjacent storeys. Unlike conventional or suspended zipper braced frames, the braces on one side of the braced span—along with the adjacent columns and ties—are part of a vertical truss system that is hinged at the base and designed to remain elastic until the near collapse limit state has been reached. The braces on the other side of the braced span consist of buckling‐restrained braces and are designed to provide energy dissipation. The design procedure stems from a design method proposed in the past for rocking eccentrically braced structures and applies capacity design principles. The accuracy of the procedure is proved by means of nonlinear dynamic analysis of multistorey systems with different geometric and mechanical properties. To highlight further the qualities of the examined type and evaluate the cost‐effective range of application, a comparison is made with other braced types in terms of cost of structural steel and seismic performance.
Natural‐Light‐Initiated 3D Macro Zigzag Architecture of Graphene‐Reinforced Polystyrene for Gravity‐Driven Oil and Water Separation
Authors: Baig Nadeem , Saleh Tawfik A. 
Published: September 2018

AbstractSuperhydrophobic 3D robust materials are introduced for the separation of hexane and water. For the first time, novel 3D zigzag polystyrene on graphene‐incorporated polyurethane (3D zz‐PS/GR/PU) is prepared using exclusively natural sunlight without any chemical initiator. The zigzag polystyrene growth is accomplished by polymerizing the styrene vapors. The natural sunlight provides a compact 3D zz‐PS/GR/PU material with superoleophilic and hydrophobic channels that allow for the rapid passage of oil, whereas water is entirely prevented from passing. The 3D zz‐PS/GR/PU compact channels are transformed into the compressible material by treating them with toluene without affecting the hydrophobicity of the material. The 3D zz‐PS/GR/PU displays a high‐water contact angle of approximately 150°. The developed materials are characterized by FTIR, SEM, and BET. The graphene incorporation makes surface area of the 3D zz‐PS/GR/PU substantially large compared with PU. It is improved from 15 to 67 m2 g−1. The pore size of the adsorption and desorption in the 3D zz‐PS/GR/PU is also reduced from 354 and 352 Å to 34 and 33 Å. The 3D zz‐PS/GR/PU satisfies the requirement of high‐demanding superhydrophobic materials, like a low‐cost fabrication process, reusability, and tunability. This strategy can trigger large‐scale production with a controlled morphology.
Techno‐economic analysis (TEA) of microbial oil production from waste resources as part of a biorefinery concept: assessment at multiple scales under uncertainty

Published: September 2018

AbstractBackgroundMicrobial oils – often termed single cell oils (SCOs) – offer an alternative to terrestrial oil crops across the energy, food and chemical industries. In addition to oils, a range of secondary metabolites can be produced from the heterotrophic organisms as part of a biorefinery system. Techno‐economic analysis (TEA) is an important tool for evaluating economic viability, and although TEA is subject to high uncertainties where production is still at the laboratory scale, the tool can play a significant role in directing further research to evaluate suitability of scale‐up.ResultsSCO production from the oleaginous yeast Metschnikowia pulcherrima using sucrose, wheat straw and distillery waste feedstocks was evaluated at two production scales. At a scale of 100 t year−1 oil production a minimum estimated selling price (MESP) of €14 000 t–1 was determined for sucrose. This reduced to €4–8000 t–1 on scaling to 10 000 t year−1, with sucrose and wheat straw yielding the lowest MESP.ConclusionsFeedstock price and lipid yield had the greatest impact on overall economic return, though the valorization of co‐products also had a large effect, and further play between feedstock and system productivity strategies could bring the price down to be competitive with terrestrial oils in the future. The novel approach demonstrated here for the first time integrates uncertainty into economic analysis whilst facilitating decision‐support at an early technology development stage. © 2018 Society of Chemical Industry

AbstractBackgroundβ‐cyclodextrin modified g‐C3N4 (β‐CD/g‐C3N4) nanosheets were successfully synthesized and developed as a novel drug carrier of doxorubicin hydrochloride (DOX•HCl). The prepared samples were characterized by Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD) and transmission electron microscopy (TEM). The drug‐loading and drug release was measured by a UV–visible spectrophotometer. Moreover, cell viability tests were carried out to evaluate the inhibition ratio of β‐CD/g‐C3N4‐DOX•HCl and bulk g‐C3N4‐DOX•HCl.ResultsThe FTIR result confirmed that β‐CD and g‐C3N4 are linked by hydrogen bonds. The XRD and TEM results showed that β‐CD/g‐C3N4 has nanosheet structure with size range 150–300 nm. The drug‐loading ratio rises sharply in the first 14 h and reaches a maximum of 93%. Moreover, β‐CD/g‐C3N4 nanocomplex showed a pH‐responsive DOX•HCl release with a release ratio of 80% at pH = 5, which is two times higher than that of bulk g‐C3N4. Cell viability tests demonstrated that the β‐CD/g‐C3N4‐DOX•HCl exhibit a higher inhibition ratio on MG63 cells than bulk g‐C3N4‐DOX•HCl.Conclusionβ‐CD/g‐C3N4 nanocomplex achieves an ultrahigh drug‐loading capacity and pH‐responsive release and visualization of the cell phagocytic process. The results indicate that the β‐CD/g‐C3N4 nanocomplex can be developed as a promising luminescence carrier for drug delivery. © 2018 Society of Chemical Industry
