Authors: Zhang Beibei , Wang Gang , Ma Shenghua , Wang Hui , Bai Jinbo 
Published: January 2022

AbstractBiomass, as a green and renewable energy source, can be procured from a broad range of sources and is low in cost. The full exploitation of biomass could reduce the dependence on and consumption of fossil fuels, and is conducive to the protection of the environment. The prevention of corrosion of metals is an issue considered problematic in many fields, including in industrial production among others. Many anticorrosion materials are expensive and are noxious to the environment. This is an important issue that anticorrosion workers cannot ignore. This study proposes the use of biochar epoxy to boost the barrier properties of the coating, which is both economical and eco‐friendly. The incorporation of biochar can reduce the porosity of the coating and complicate the path of the corrosive media towards the steel substrate. Additionally, it can also reinforce the anticorrosion performance of the coatings. First, this article introduces the effect of biochars with different ultrasonic durations on the anticorrosion performance of anticorrosion coatings. After finding the biochar with the optimal ultrasonic duration, the effects of biochar on the anticorrosion performance of the coatings at different temperatures are assessed and the changes in its anticorrosion performance following soaking are discussed. The discussion concludes that applying biochar to anticorrosion coatings provides a feasible type of coating for anticorrosion work.

AbstractReplacing petroleum‐based chemicals with biomass‐based alternatives is becoming more and more important for the development of a low‐carbon economy around the world. The latest life cycle assessment displayed that partially replacing phenol with biobased lignin in the process of synthesizing phenolic resin adhesives used in wood panels industry can remarkably reduce carbon emissions and negative environmental impact. The macromolecular structure of lignin is similar to that of phenolic resin and the basic structure unit is similar to that of the phenol, thus endowing it with the potential to substitute phenol and reduce the release of formaldehyde in the preparation process of phenolic resin. Importantly, the lignin‐based adhesive exhibits improved performance and reduced cost compared with the petroleum‐based adhesive due to the reduced adding amount of petroleum‐based volatile components. However, the intrinsic large steric hindrance, structural heterogeneity, and low activity of the natural lignin limit its further application in the adhesive. Many researchers have developed the activation methods such as physical modification, chemical modification, and biological modification to overcome these issues. The different modification of the lignin and their application in the adhesive area are mainly summarized here. Besides, the modification methods and the curing mechanism are also discussed.
Exploring the antecedents of green and sustainable purchase behaviour: A comparison among different generations
Authors: Casalegno Cecilia , Candelo Elena , Santoro Gabriele 
Published: January 2022

AbstractThis paper investigates whether generation matters in the intention to buy green and sustainable products and, simultaneously, examines the antecedents of green and sustainable buying behaviour among three different generational cohorts (X, Y, and Z). By doing this, the present paper fills the gap regarding studies addressing the relationships between age and sustainable behaviour which have not included actual green and sustainable buying intention, along with the gap regarding studies only focussing on one or two (X and Y) generational cohorts. Drawing on the generational cohort theory, and by using a survey approach involving three samples of specific generations (X, Y, and Z), as well as by testing several hypotheses through ordinary least squares regression models, the paper finds that: (a) age plays a key role in the choice of green and socially friendly products, and (b) environmental concern and perceived consumer effectiveness are strong antecedents of green and sustainable purchase behaviour for all generational cohorts. This is also true for environmental citizenship, but this only applies to generations Y and Z. Finally, collectivism is only an antecedent of sustainable purchase behaviour for generation Z.

AbstractBackgroundRecent studies have analyzed the combination of suction‐assisted lipectomy (SAL) and vascularized lymph node transfer (VLNT) in lymphedema treatment, reporting positive outcomes. However, it is difficult to draw conclusions due to the heterogeneity of the studies. Aim of this prospective study is to evaluate the effectiveness of the combination of VLNT and SAL in lymphedema treatment.Patients and methodsBetween January 2016 and May 2019, 94 patients with upper or lower limb stage IIb‐III lymphedema were enrolled and treated with the gastroepiploic VLNT followed by SAL. Patients were prospectively evaluated through circumference measurement and clinical examination, including number of episodes of cellulitis.ResultsAmong patients enrolled in the study 83 were affected by lower limb lymphedema (LLL) and 11 were affected by upper limb lymphedema (ULL). Average follow‐up was 3 ± 0.8 years. In the LLL group, the mean circumference reduction rates (CRR) were 60.4, 56.9, 29.6, and 55.4% above and below the knee, above the ankle, and at the foot level, respectively. A statistically significant difference was noted at all the levels (p < .05), but above the ankle (p = .059). Regarding the ULL group, the mean CRR were 80.7, 60.7, 65.0 and 49.6% above and below the elbow, at wrist and at mid‐hand, respectively. CRR were reported at all the levels but no statistical difference was noted. The number of episodes of cellulitis dropped significantly (p < .05).ConclusionThis study supports the use of VLNT+SAL in lymphedema grades IIb‐III, with important implications for the clinical practice.

Authors: Zhao Zhihong , Wang Bin , Tan Rui , Liu Wenjing , Zhang Minghui 
Published: January 2022

AbstractIn this study, the transverse relaxation time (T2) of activated carbon (AC) in different relative environment humidity was detected firstly by low‐field nuclear magnetic resonance (LFNMR). The pore size (diameter) of AC distributions was calculated by the relationship between T2 and surface relaxation rate (ρ), where ρ was obtained by the detection of nine porous materials with known pore size. The results showed that the pore size distributions of AC calculated by ρ < 0.19 nm/ms were in good agreement with that obtained by nitrogen adsorption method and proved that LFNMR as a new detection method was feasible for characterizing AC pore size distribution.

AbstractThe production of petroleum‐based polymers in huge amounts is perilous for our ecosystem and oil reserves. The use of biodegradable polymers instead of synthetic polymers for various commodity, engineering, and biomedical applications remains the overriding concern of the researchers in last decades. Although poly(lactic acid) (PLA) is considered to be the most befitting substitute for conventional petroleum‐based products because of its superlative mechanical properties, material & processing cost, and non‐toxicity, they have some consequential limitations for various applications because of their slow rate of crystallization, low thermal stability, high brittleness, and low toughness. To overwhelm these deficiencies during the last two decades, researchers have developed various techniques to tailor the properties of PLA, that is, blending with other polymers or using additives such as nanofillers. Among all the nanofillers, for example, carbon nanotubes and organoclays, polyhedral oligomeric silsesquioxanes (POSS) was found the most promising nanofiller because of its organic and inorganic nanostructure and fine dispersion into PLA matrix. This article reviews all the investigations relevant to POSS incorporation into PLA or blends of PLA with other polymers to compare the mechanical, morphological, and physical properties of the ameliorated composites and the neat PLA.
Effects of printing parameters on the tensile behavior of 3D‐printed acrylonitrile styrene acrylate (ASA) material in Z direction

Published: January 2022

AbstractFused deposition modeling (FDM), which is a popular and widely additive manufacturing technique, opens alternative possibilities for complex geometries that are hard to manufacture using classic manufacturing techniques. Its use in functional products is however limited because of anisotropic strength issues, where the strength of FDM‐fabricated parts in the build direction (Z direction) can be significantly lower than in the X–Y directions. This work aims at addressing this particular point for a not‐well‐known polymer, namely acrylonitrile styrene acrylate or ASA. Using central composite design and response surface methodology, the nozzle temperature (A), printing speed (B), and layer thickness (C) were studied in a systematic manner to evaluate their effects on the Z‐direction tensile properties of 3D‐printed ASA's samples. Analysis of variance results demonstrate that layer thickness is the most influential printing parameter on interlayers bonding. The best tensile properties for 3D‐printed ASA parts were achieved with parts produced at A = 270°C, B = 60 mm s−1, and C = 0.155 mm. Scanning electron microscopy observation confirms that printing ASA material with those optimum parameters clearly improves the interlayers' bonding in the build direction.
Polyurethane‐layered double hydroxide nanocomposite foam: in situ synthesis by reaction injection molding and characterization

Published: January 2022

AbstractIn the present work, a series of polyurethane ayered double hydroxide (PU‐LDH) nanocomposite molded foams were developed using Mg/Al LDH as the chemical blowing agent. Morphological, physicochemical, thermal and mechanical characterizations were performed to elucidate the mechanistic insight of the chemical blowing effect of the LDH and subsequently its enhanced blowing (foam formation) property. The characterization of standard urethane peaks by Fourier transform infrared spectroscopy attenuated total reflectance (FTIR‐ATR) studies confirmed PU foam formation. The DSC thermogram of all the PU‐LDH nanocomposite foams shows a low temperature glass transition for the soft segment (Tg) and a high temperature peak related to the hard segment. The TGA and DSC studies also reveal an improved phase separation behavior of the nanocomposite foam with increase in LDH content. The volume of the foam generated is increased with increase in LDH. The developed PU‐LDH nanocomposite foams are flexible and light weight. The results demonstrate that LDH can be an alternative cost effective and environmentally friendly blowing agent, whilst supporting other thermal, mechanical and chemical properties through synergistic optimization for the intended/specific application. © 2022 Society of Industrial Chemistry.
Test use and assessment practices of school psychology training programs: Findings from a 2020 survey of US faculty

Published: January 2022

AbstractThe last comprehensive study to examine the assessment practices promoted by school psychology programs was published 25 years ago (i.e., Wilson & Reschly, 1996). Since then, significant changes to assessment theory and practice have occurred. Data from a 2020 survey of directors of school psychology programs were collected to gain an understanding of current graduate training in test use and assessment. Results were compared to a current survey of practitioners as well as past surveys of trainers. Results indicate that the assessment instruments used most frequently by practitioners tend to be those that are strongly emphasized in training programs. There were significant changes over time, most notably a large increase in the extent to which programs emphasize rating scales. Programs continue to strongly emphasize standardized, norm‐referenced tests, particularly tests of cognitive abilities and academic achievement. Programs also continue to emphasize behavioral observation methods. In contrast to our expectations, results also reveal a persistent emphasis on low‐value instruments such as projective tests. The implications of these findings for training and practice are discussed.
Insights into end‐capped modifications effect on the photovoltaic and optoelectronic properties of S‐shaped fullerene‐free acceptor molecules: A density functional theory computational study for organic solar cells

Published: January 2022

AbstractNon‐fused ring electron acceptors with different end‐capped substituents were designed to construct efficient organic solar cells (OSCs). End‐capped modification of acceptor materials is an efficient approach for developing high performance OSCs. In this report, five new S‐shaped fullerene‐free acceptor molecules (3P1 to 3P5) have been designed and examined through density function and time‐dependent density functional theories (TD‐DFTs). Designed molecules have twisted backbone with different out‐of‐plane rings that cause high solubility in dilute solvent. Different optoelectronic and photovoltaic properties of newly designed S‐shape molecules have been examined and explored through DFT tools. Orientation of frontier molecular orbitals (FMOs), light absorption range, exciton binding energy (Eb), oscillating strength (f), open circuit voltage (Voc), and transition density matrix (TDM) analysis have been performed for 3P1 to 3P5 molecules. Further, electron and hole reorganization energies are also estimated with excitation energy. Results of different computed parameters have recommended that these designed molecules are effective contributors for possible applications in the field of OSCs.
Factors associated with successful extubation following the first course of systemic dexamethasone in ventilator‐dependent preterm infants with or at risk of developing bronchopulmonary dysplasia

Published: January 2022

AbstractObjectivesWe aimed to identify factors present at the start of an initial course of systemic dexamethasone that would be associated with successful extubation in mechanically ventilated neonates <30 weeks gestational age (GA) with or at risk of developing bronchopulmonary dysplasia (BPD).MethodsWe studied a retrospective cohort of neonates (23+0−29+6 weeks GA), with or at risk of developing BPD, prescribed their first course of systemic dexamethasone to aid in extubation from mechanical ventilation. The data collected only pertained to the first course of dexamethasone. Neonates given dexamethasone for airway edema were not included. The primary outcome of interest was successful extubation (i.e., extubated within 14 days of starting dexamethasone and remaining extubated for at least 7 days). Binary logistic regression was employed.ResultsA total of 287 neonates were included. Each additional week of GA at birth led to a 1.53 increase in the odds of successful extubation (95% CI: 1.122–2.096, p < 0.01). Higher average fraction of inspired oxygen (FiO2) requirements in the preceding 24 h resulted in a 0.94 decrease in the odds of successful extubation (p < 0.05) and higher mean airway pressure (MAP) resulted in 0.76 decrease in odds of successful extubation (p < 0.01).ConclusionsMechanically ventilated neonates with or at risk of developing BPD, born at <30 week GA and initiated on dexamethasone to facilitate extubation, had a lower likelihood of successful extubation by Day 14 if they had younger GA at birth, and at the time of commencing steroids had higher MAPs and had higher oxygen requirements.
A rare case of common variable immunodeficiency and hepatopulmonary syndrome
Authors: Lawton Emily , Holmes‐Liew Chien‐Li 
Published: January 2022

AbstractHepatopulmonary syndrome (HPS) is the triad of liver disease, hypoxia and intrapulmonary shunt. In this case report, we describe an immunocompromised female with a background of common variable immunodeficiency (CVID) who presented with haemoptysis and dyspnoea. Investigations demonstrated significant hypoxaemia and intrapulmonary right‐to‐left shunting. Further evidence revealed advanced liver cirrhosis, and a diagnosis of HPS was made. This extremely rare association of CVID and HPS is one of the few cases reported in the literature.
Embedded control of cell growth using tunable genetic systems
Authors: Fusco Virginia , Salzano Davide , Fiore Davide , di Bernardo Mario 
Published: January 2022

AbstractWe present an embedded feedback control strategy to regulate the density of a microbial population, that is, the number of cells into a given environment, allowing cells to self‐regulate their growth rate so as to reach a desired density at steady state. We consider a static culture condition, where cells are provided with a limited amount of space and nutrients. The control strategy is built using a tunable expression system (TES), which controls the production of a growth inhibitor protein, complemented with a quorum sensing mechanism for the sensing of the population density. We show via a simplified population‐level model that the TES endows the control system with additional flexibility by allowing the set‐point to be changed online. Finally, we validate the effectiveness of the proposed control strategy by means of realistic in silico experiments conducted in BSim, an agent‐based simulator explicitly designed to simulate bacterial populations, and we test the robustness of our design to disturbances and parameters' variations due, for instance, to cell‐to‐cell variability.
Distributive hydraulic engineering, cross‐scale landscape planning, and climate change resilience: On the water‐adaptive strategy in the Huai'an–Yangzhou Section of China's Grand Canal

Published: January 2022

AbstractWater system plays a key role in the coupled human‐nature system, and ancient people's experiences to build a water‐adaptative way of life still shed light on human's pursuit for climate resilience today with their innate traditional ecological wisdom. In this paper, taking the Huai'an‐Yangzhou Section of China's Grand Canal, and particularly its hydraulic engineering system as an example, we show the system's success in addressing the multi‐dimensional challenges in a historical geographical context, as well as its landscape‐shaping power across the entire lower Yellow‐Huai River Basin up until today. Therefore, we argue that the system is not merely a hydraulic engineering project, but a cross‐scale adaptive strategy that has deeply impacted generations of people's way of livelihood with its intrinsic resilient nature. We attribute the success to the advantages brought about by the “distributive hydraulic engineering” approach, which is reflected in the ancient Grand Canal‐management, over the “master‐structure dependent” approach which appears to be the common practice in modern hydraulic engineering. For testing the hypothesis, we build complex system models representing the two approaches with the Qingkou Hydraulic Nexus as an example, and by running long‐term simulation, we evaluate the performance of the two approaches with respect to long‐term resilience. We show from a complex network perspective that the former has significant flexibility advantages, and outperforms the former in multi‐goal fulfillment capacities and long‐term resilience especially under a low‐tech, tight resource constraints condition. We conclude the paper with discussions on the implications of the findings, and argue that though with limitations, the traditional ecological wisdom as reflected in the Grand Canal case, with its holistic approach and flexibility design, still sheds lights on today's large‐scale hydraulic engineering projects that pursue a resilient solution for long‐term adaptive survival for the mankind.
