Published: December 2021

AbstractBacterial cellulose (BC) has received attention in research because of its unique characteristics. Especially, it has emerged as a very promising and versatile candidate for biomedical applications. In this study, it was aimed to boost some structural and biological properties of BC by crosslinking, which play important role in medical field. Synthesized, purified, and neutralized BC pellicles were cross‐linked (X‐linked) in different concentrations (5, 10, and 20 wt/vol%) with citric acid/sodium hypophosphite. Formation of X‐Links confirmed by Fourier transform‐infrared. Obtained spectrums showed that the density of X‐links would raise up to a limit with increasing the concentration of citric acid. X‐ray diffraction data analysis of samples showed a decline in crystallinity of samples with increasing the intensity of X‐linking treatment. Scanning electron microscope images and MTT assay confirmed the better cell adhesion, viability and proliferation for X‐linked samples and no toxicity was observed for all samples including (non‐X‐linked and X‐linked). It was concluded that some important structural and biological properties of BC (which were very critical for biomedical applications) were related mutually and could be modified with X‐linking treatment simultaneously.

AbstractVegetable oil‐based shape memory polyurethane (SMPU) has been rapidly developed in the field of advanced polymeric materials due to its unique responsive characteristic. This research aimed to investigate the effect of prepolymer reaction time on the microphase separation, soft segment crystallinity, shape memory, and tensile properties of palm kernel oil polyol (PKO‐p)‐based SMPU. The SMPU samples were prepared via two‐step bulk polymerization process utilizing 4,4‐methylenebis (cyclohexyl isocyanate) (HMDI), polycaprolactone diol (PCL) and 1,4‐butanediol (BD). The reaction time after the addition of PKO‐p varied from 0.5 to 2.5 h in prepolymer synthesis. This reaction time resulted in excellent microphase separation and improve shape memory properties. The Fourier transform infra‐red analysis revealed that the degree of microphase separation of the polyurethane elastomer (PUE) increased with increasing prepolymer reaction time. In consequence, the shape fixity behavior of the PUE samples improved. The tensile strength and strain at break of PUE increased with increasing reaction time up to 2.0 h. However, when the reaction time was prolonged to 2.5 h, both values decreased. Thus, the results showed the advantages of using PKO‐p, which can minimize the usage of petroleum‐based polyol and improve the tensile and shape memory behavior of the PKO‐p‐based SMPU.

Published: December 2021

AbstractHerein, the cross‐linking density was adjusted controllably by tuning the curing reaction to gain polydimethylsiloxane (PDMS) elastomers with different mechanical performances. First of all, the cross‐linking network of PDMS was adjusted by tuning the parameters of the fabrication process such as curing temperature, curing time, and component ratio. Lowering the temperature, shortening the curing time, and using less curing agent were discovered to effectively reduce the cross‐linking density. Then, the effects of important factors on cross‐linking density, including the fabrication process, the time for post‐curing, and the content of carbon nanotube (CNT), were thoroughly discussed. Furthermore, the dynamic mechanical performance, mechanical characteristics, and viscoelastic properties of PDMS and PDMS/CNT composites were studied based on the regulation of the cross‐linking network. The stronger the cross‐linking density, the higher the storage modulus, the greater the restriction on the molecular chain of silicone rubber. Besides, the post‐curing for 5 months and the introduction of CNT fillers appeared to be a viable option for promoting the cross‐linking reaction with higher density and thereby strengthening the mechanical properties of PDMS.

Published: December 2021

AbstractCoordination flexibility assisted porosity has been introduced into an Iron‐isonicotinate metal‐organic framework (MOF), (Fe(4‐PyC)2 ⋅ (OH). The framework showed CO2‐specific gate opening behavior, which gets tuned as a function of temperature and pressure. The MOF′s physisorptive porosity towards CO2, CH4, and N2 was investigated; it adsorbed only CO2 via a gate opening phenomenon. The isonicotinate, representing a borderline soft base, is bound to the hard Fe3+ centre through monodentate carboxylate and pyridyl nitrogen. This moderately weak binding enables isonicotinate to spin like a spindle under the CO2 pressure opening the gate for a sharp increase in CO2 uptake at 333 mmHg (At 298 K, the CO2 uptake increases from 0.70 to 1.57 mmol/g). We investigated the MOF′s potential for CO2/N2 and CO2/CH4 gas separation aided by this gating. IAST model reveals that the CO2/N2 selectivity jumps from 325 to 3131 when the gate opens, while the CO2/CH4 selectivity increases three times. Interestingly, this Fe‐isonicotinate MOF did not follow the trend set by our earlier reported Hard‐Soft Gate Control (established for isostructural M2+‐isonicotinate MOFs (M=Mg, Mn)). However, we account for this discrepancy using the different oxidation state of metals confirmed by X‐ray photoelectron spectroscopy and magnetism.

AbstractIntrodctionPrevious studies have argued that people tend to isolate themselves from negative information. This tendency is modulated by the individual's role in social interaction, that is, as an initiative actor (e.g., “I hit Tom”) or a passive recipient (e.g., “Paul hits me”). Depressed patients tend to focus on negative aspects of themselves and cope with situations passively. It is still an open question how the actor/recipient role affects the behavioral and neural responses to self in depression.MethodsThe present study adopted functional magnetic resonance imaging (fMRI) technology to investigate behavioral and neural responses to self (as an actor/recipient) in depressed patients and the matched healthy controls when attributing negative events.ResultsCompared with healthy controls, depressed patients showed more self‐attribution for negative events. Depressed patients showed increased brain activity in the dorsal medial prefrontal cortex (dmPFC) subsystem of the default mode network (DMN) when they played recipient role in self‐related negative events. Activity of the dmPFC subsystem was negatively correlated with depressed patients’ self‐attribution for negative events in recipient condition. While decreased brain activity in the medial temporal lobe (MTL) subsystem was observed in depressed patients when they played the actor or recipient role in self‐related negative events. Activity of the MTL subsystem was negatively correlated with depressed patients’ reaction time when they played recipient role in selfrelated negative events.ConclusionThese results implicated that depressed patients manifested the negative self‐view. Actor/recipient role affected their activation patterns in the DMN which were different from the healthy controls. The correlation between the abnormal brain activations of the DMN and the behavioral performances might manifest more easily when depressed patients played recipient role in negative events.

Published: December 2021

AbstractAddressing environmental concerns in supply chain is a challenge, where one of the greatest difficulties is quantifying the environmental impacts. This quantification in abstract units is often done, but it does not always allow decision‐makers to understand how their supply chains' influence the environment. In this regard, environmental quantification in monetary units can be an asset but, on this, not enough information exists about their application in supply chain. This work intends to develop a decision support tool for the design and planning of closed‐loop supply chains accounting for the monetization of environmental impacts, exploring the most used monetization methods. As main contributions, this paper supports the understanding of the methodological basis of the main monetization methods. This is then embedded into an optimization‐based decision supporting tool that defines the design and planning of supply chain allowing to conclude on the most appropriate methods to used when considering supply chain environmental performance. From the results is also demonstrated how the different monetization methods can influence the supply chain design and planning. A set of main recommendations to decision‐makers and researchers is provided that support the definition of supply chain strategy towards greener systems allowing the evolution of the currently practiced knowledge.

Published: December 2021

AbstractIn the last years, sustainability has become a successful, relevant, critical factor in several food industries. The adoption of a sustainable marketing strategy contributes positively to changes in society in terms of environmental, social and economic development. The relationship between sustainability and business performance has been widely debated in management and organisational studies. However, despite its importance and relevance, fishery sustainability has not been systematically considered by scientific studies. This paper identifies and analyses the critical factors that describe the propensity towards sustainable development for large companies within the Italian fishery sector. For this purpose, the relationships among the following latent variables were analysed: sustainable social behaviour, sustainable environmental behaviour, sustainable marketing, and return on investment. A theoretical research model has been proposed and empirically tested using a methodology based on structural equation modelling.

Published: December 2021

AbstractBackground and objectivesRice is an important staple food that is often stored for long periods (e.g., 2 years) but is subject to aging effects that reduce quality. Therefore, a sensitive freshness detection method for long‐term paddy storage is required.FindingsThis study stored five varieties of Chinese paddy at 4°C, 15°C, 20°C, or 35°C for 10 months, and then analyzed their solvent retention capacity (SRC), freshness index, contents of fatty acids, amylose, protein and soluble amino acids, and their thermal and thermomechanical properties. The results show that the SRC values in water, 5% NaHCO3, 5% lactic acid, and 50% sucrose solution decreased with increases in storage temperature and duration, with no differences among the five varieties. The four SRC values were negatively correlated with an existing freshness index (D615–D690), which could not distinguish between the effects of storage temperature and duration. With the SRC values for newly harvested paddy stored at 4°C used as a reference, the mean and accumulated SRC reductions were found to increase with storage temperature and duration. A protocol for rice freshness detection was developed based on these four SRC values.ConclusionPaddy with a mean SRC reduction of ≤25% is eligible for preservation, that with a mean of 25%–30% is slightly ineligible for preservation, and that with a mean of >30% is unfit for preservation. If the sum of the four SRC reductions is ≤100%, the paddy is eligible for preservation, a sum of 100%–120% indicates that it is slightly ineligible for preservation, and a sum >120% indicates that it is unfit for preservation.Significance and noveltyThis novel method based on SRC values provides an improved way to assess the freshness of stored rice.
A dynamic sample augmentation Kriging metamodeling method for industrial residue hydrogenation process
Authors: Wang Yalin , Yi Kemin , Liu Chenliang , Wang Kai , Yuan Xiaofeng 
Published: December 2021

AbstractResidue hydrogenation process (RHP) plays an important role in efficient utilization of heavy oil resources. The high‐fidelity model of RHP is so complex that its optimization cost is expensive and even intractable. Furthermore, in the actual industrial processes, due to the low sampling frequencies of some sensors, only a few sampling points can be obtained with some missing values. The insufficient samples can directly affect the performance of the final model. Therefore, a new adaptive dynamic sampling (ADS) method for Kriging metamodeling is proposed. Based on a small number of valid industrial sample points, the proposed method adaptively obtains key information sampling points and selectively adds key information sampling points to update the model. First, the difference maximization strategy and the outlier distance strategy are proposed to obtain new sampling points with both global and regionalized information. Then, the new key points are used to iteratively update the Kriging predictor to obtain satisfactory accuracy. Finally, the calculation result of benchmark cases and two actual experiments validate the effectiveness of the proposed method for constructing surrogate models of complex industrial processes.

AbstractIntroductionWe examined relationships of body mass index (BMI) with cognition in middle‐aged adults at Alzheimer's disease (AD) risk due to parental family history.MethodsParticipants are offspring of AD patients from the Israel Registry of Alzheimer's Prevention (N = 271). Linear regressions assessed associations of BMI and cognition, and whether associations differed by maternal/paternal history. Analyses of covariance examined associations of long‐term trajectories of BMI with cognition.ResultsHigher BMI was associated with worse language (P = .045). Interactions of BMI with parental history were significant for episodic memory (P = .023), language (p = .027), working memory (P = .006), global cognition (P = .008); associations were stronger among participants with maternal history. Interactions of BMI trajectories with parental history were significant for episodic memory (P = .017), language (P = .013), working memory (P = .001), global cognition (P = .005), with stronger associations for maternal history.DiscussionHigher BMI and overweight/obese trajectories were associated with poorer cognition in adults with maternal history of AD, but not those with paternal history.

AbstractLarge amounts of water are consumed by urban parks in arid regions such that efficient irrigation practices are needed. In Phoenix, Arizona, extensive turf grass areas are supported using flood or sprinkler irrigation that also require fertilizers. Residential green waste compost has the potential to serve an alternative fertilizer if its higher costs can be offset through water conservation. In this study, we conducted an ecohydrological monitoring and modelling effort for a compost experiment in two urban parks with either flood or sprinkler irrigation. Soil moisture, evapotranspiration and turf greenness data along with a soil water balance model were used to determine if compost treated plots were different from control plots in each park. After building confidence in the model through comparisons to data, we created long‐term scenarios to explore differences between flood and sprinkler irrigation practices and analyse the effect of changes in irrigation scheduling. Multiple lines of evidence indicated that green waste compost applications did not appreciably change soil moisture or vegetation conditions in either urban park. Major differences, however, were noted between the two irrigation practices in terms of the seasonality of the soil water balance, plant water stress and the sensitivity to interannual fluctuations in precipitation. Model scenarios showed that significant irrigation reductions from 15% to 30% could be achieved, in particular with small changes in watering depths. As a result, irrigation management in urban parks can meet water conservation targets that potentially offset green waste compost costs while also benefitting the soil water balance through reductions in water losses.

AbstractBackgroundPain is known to interrupt attentional performance selectively. In a previous study, we showed that the interruptive effect of thermal pain on attention could persist up to 1500 ms after painful stimulus offset, but whether the pain modality affects this subsequent interruptive effect remains unclear.MethodsThe present study was conducted to determine the time course of the interruptive effect of electrically induced pain on orienting and executive attention using various intervals between electric stimulation and attentional tasks (0, 250, 500, 750, 1000, 1250 and 1500 ms) and three study groups (pain, non‐pain and control). We performed two separate experiments in which participants performed a spatial cue task (Experiment 1) and the Stroop task (Experiment 2). Participants in the pain and non‐pain groups received brief electric somatosensory stimulation, and those in the control group received no physical stimulus. We compared the performance of the three groups under the interstimulus interval (ISI) conditions.ResultsThe impairment of orienting attention prevailed under the first six ISI conditions in the pain and non‐pain groups (F2, 63 = 5.72, p < 0.01); executive attention was not affected (F1,66 = 1.64, p = 0.20), confirming the persistence of the interruptive effect after stimulus offset.ConclusionsThis study demonstrated the interruptive effect of somatic stimulation on subsequent orienting attention performance, with no effect on executive attention. These findings suggest that pain has differential effects on the components of attention, depending on its modality and salience.SignificanceThis study confirmed that pain had a selective subsequent interruptive effect on attention and found that the time course of the interruption depended on the modality of pain and the component of attention.

Published: December 2021

AbstractMany researches have been devoted to rechargeable power generators that can store (but also release) energy. This availability is ensured through (e. g.) the oxygen evolution reaction (OER). However, (i) large values of the overpotentials and (ii) a progressive detriment of the anode (graphite) electrode limit the ultimate device. In view of enhancing the electrode performances, graphite was protected by following different strategies, which oblige to follow precise preparation protocols.Here, we prove that a thin layer of free‐base porphyrin molecules is able to protect the underneath graphite electrode from detriment even if many (about 100) electrochemical cycles are performed.
Taking back control over the economy: From economic populism to the economic consequences of populism
Authors: Benczes István 
Published: December 2021

AbstractEconomic populism was once recognized as a paradigmatic understanding of the boom‐and‐bust cycles of Latin America. By now, the concept has lost its analytical strength and academic attractiveness. Nevertheless, policy analysts cannot neglect the supply side analysis of contemporary populism, that is, what populists actually do once elected into government. Adopting and operationalizing the ideational definition of populism, the article identifies three major consequences of populist incumbency: (1) the inclination of populists to embark on redistributive policies favoring “our” people against “others,” (2) their critical attitude toward autonomous organizations, professionals, and institutions, and (3) their antagonistic relationship with the competitive market mechanism. The article demonstrates that populism is no longer about myopic and irresponsible policies; instead, populists tend to disregard the institutional constraints of economic decision making.

Published: December 2021

The Permian mafic dykes of Santanghu Basin offer an opportunity to study the nature of mantle source and tectonic setting of the basin, as well as to provide the theoretical basis for structural transformation of East Junggar region. In this study, zircon U–Pb geochronology, mineral composition analysis, whole‐rock elemental, and Sr‐Nd isotopic geochemistry were conducted to explore the origin and evolution of the primitive magma. LA‐ICPMS zircon U–Pb dating yields ages at 269 Ma. The elemental geochemistry results suggest enrichments in Ba, Pb, and Sr but depletions in Nb, Ta, Zr, and Hf, which indicate that the magma source was influenced by fluid metasomatism. All samples show moderate initial Sr‐Nd isotope results ((87Sr/86Sr)I = 0.704299 to 0.704490 and εNd(t) = +6.16 to +6.83) and have high Sm/Yb ratios, which suggest that the diabases were derived from partial melting of 5%–7% spinel‐garnet Iherzolite lithospheric mantle. Combined with petrological, geochronological data, and the regional tectonic background, it is interpreted that the diabases from Santanghu Basin originated from lithospheric mantle metasomatized by subduction fluids under the background of intracontinental extension.
