AbstractThree lanthanide complexes (Ln=Gd, Eu) based on a DO3 A ([Ln(L1)]) or DO2 A ([Ln(L2–3)]+) platform appended by a redox active TEMPO‐based arm were prepared. Complex [Ln(L2)]+ shows an alkyne arm, offering the possibility of postfunctionalization by click reaction to yield [Ln(L3)]+. The complexes demonstrate a redox response whereby the hydroxylamine, nitroxide and oxoammonium forms of the arm can be obtained in turn. Luminescence measurements on the europium complexes support an octadentate (L1, L3) or heptadentate (L2) chelation by the ligand, with one water molecule in the inner coordination sphere. The relaxivity was determined from 20 kHz to 30 MHz by fast‐field cycling NMR. The three GdIII complexes under their hydroxylamine form [Gd(L1)] and [Gd(L2–3)]+ show r1 values of 7.0, 5.1 and 5.0 mM−1 s−1 (30 KHz), which increase to 8.8, 5.5 and 6.1 mM−1 s−1 in the nitroxide form. The radical complexes are not toxic against M21 cell lines, at least up to 40 μM. By using EPR spectroscopy we establish that they do not penetrate the cells with the exception of [Eu(L2)]+.

AbstractFood loss and waste are major issues in the food industry, and they affect all stages of the food supply chain (FSC). Food loss and waste are linked to environmental deterioration, economic loss, and an increase in hunger. Therefore, the food industry requires sustainable consumption and production (SCP) to reduce losses and waste. The circular economy (CE) concept has become a popular strategy for reducing food waste and boosting sustainability. Therefore, with efficient reverse logistics in the FSC, food producers can help achieve sustainable development goals (SDGs) like SCP and zero hunger. In literature, minimal research has been available in identifying the CE adoption challenges in FSC. This research identifies 15 critical challenges from the literature and discussion with the panel of experts. The relationship between the challenges has been established through an interpretive structural modeling (ISM) technique. The challenges were characterized in cause–effect according to their relational intensity obtained using the grey decision‐making trial and evaluation laboratory (DEMATEL) technique. Grey's relational theory is applied in DEMATEL to minimize uncertainty and vagueness of the expert judgment. The findings of this study suggest that creating policy from the government, providing incentives, and strictly enforcing environmental regulations are the most critical challenge. Hence, by focusing on the above, the effective adoption of the CE principle is achieved. This result also suggests that by addressing the challenges of CE, corporate social responsibility (CSR) can be performed. This study provides some recommendations for the practitioners to adopt CE towards sustainable development targets.
The drivers of eco‐innovations in small and medium‐sized enterprises: A systematic literature review and research directions

Published: July 2022

AbstractThe debate on innovations that contributes to the decoupling of economic growth and environmental degradation or fosters the transition from the brown to the green economy is becoming increasingly relevant in the academic and business worlds, fuelling a research stream that is proving very interesting for its economic, environmental and social implications. Although the debate on the adoption of environmental innovations is well underway, the discussion on eco‐innovation in the context of small‐ and medium‐sized enterprises (SMEs) is at a less developed stage and deserves more attention, especially given the relevance of these companies in the economic system of several countries. Thus, this study proposes a systematic literature review of the determinants of eco‐innovation in SMEs and explores the relationships among them by starting from the criticalities highlighted in the five literature reviews of determinants of eco‐innovations in SMEs that have been recently published. The first step of the research concerns a detailed description of the selection process of the articles under consideration and of their characteristics. In the second step, 14 main categories of determinants are identified. Additionally, in the third step, as result of this investigation, three basilar research directions and 13 related research questions emerged.

Published: July 2022

AbstractA series of novel pathalide‐1,2,4‐oxadiazole analogs were synthesized for discovering novel anti‐inflammatory agents. After the assessment of their cytotoxicity in vitro, all compounds had been screened for their anti‐inflammatory activity by evaluating their inhibitory effect on LPS‐induced NO production in RAW 264.7 macrophages. SARs had been concluded, and finally compound E13 was found to be the most potent compound. This compound could also significantly decrease the production of iNOS and COX‐2. Preliminary mechanism studies indicated that compound E13 could inhibit the TLR4/NF‐κB and ERK/p38 signaling pathways. These findings indicate that E13 holds great potential to be a lead compound for discovering novel anti‐inflammatory drugs.

AbstractNine xanthone derivatives (1–9) were isolated from the roots of Polygala azizsancarii, which is a narrow endemic species for the flora of Türkiye. Based on all of the evidence, the structures of 1–9 were established as two previously undescribed xanthone O‐glucosides, 3‐O‐β‐D‐glucopyranosyloxy‐1,6‐dihydroxy‐2,5,7‐trimethoxyxanthone (1), 3‐O‐β‐D‐glucopyranosyloxy‐1,6‐dihydroxy‐2,7‐dimethoxyxanthone (2), and seven previously described xanthones, 1,3,6‐trihydroxy‐2,5,7‐trimethoxyxanthone (3), 1,3,6‐trihydroxy‐2,7‐dimethoxyxanthone (4), 1,2,3,4,7‐pentamethoxyxanthone (5), 1,3‐dihydroxy‐2,5,6,7‐tetramethoxyxanthone (6), 1,3‐dihydroxy‐4,7‐dimethoxyxanthone (7), 1,7‐dihydroxy‐3‐methoxyxanthone (8), and 1,7‐dihydroxy‐2,3‐methylenedioxyxanthone (9). The structures of the compounds were determined by spectroscopic methods, including 1D‐NMR (1H‐NMR, 13C‐NMR, DEPT‐135), 2D‐NMR (COSY, NOESY, HSQC, HMBC, INADEQUATE), and HR‐MS. The solid‐state structures of 1–4, including the absolute configurations of the stereogenic carbons of the sugar moiety in 1 and 2, were established by X‐ray crystal‐structure analyses. For the newly described compounds, the trivial names sancarosides A (1) and B (2) are proposed.

AbstractFall forage production in the northeastern United States is complicated by early onset of cool temperatures, limiting forage availability in cool‐season perennials. Annual forages planted in late summer as cover crops or supplemental forage crops may fill this niche; however, data on their nutritive value over the short fall harvest window is lacking. This study compared six annual forage crops for their forage mass and nutritive value and identified optimal harvest times based on changes between forage mass and digestibility. Monocultures of canola (Brassica napus L.), forage radish (Raphanus sativus L.), oat (Avena sativa L.), spring triticale (×Triticosecale Wittm. ex A. Camus [Secale × Triticum]), spring wheat (Triticum aestivum L.), sunn hemp (Crotolaria juncea L.), and a mixture of all six species were sown in August of 2015 and 2016 then harvested at three time points (6, 8, and 10 weeks after planting [WAP]) over the fall (September–November). Canola, oat, and spring wheat had the greatest forage mass, while sunn hemp had the least across all harvests. Canola and forage radish had the lowest neutral detergent fiber (NDF) and acid detergent fiber (ADF) and greatest in vitro true dry matter digestibilities (IVTDMd) across all harvests, while sunn hemp and the grasses declined in IVTDMd after first and second harvest. Forage mass of the fall mix was comparable to the highest yielding monoculture at third harvest only. Results suggest that forage brassicas can be harvested without compromising mass or nutritive value, while cereal grasses gained forage mass at the expense of nutritive value.

AbstractMesoscopic aggregate is important to transfer or even amplify the molecular information in macroscopic materials. As an important branch of aggregate science, aggregation‐induced emissive luminogens (AIEgens) often show slight or even no emission in solutions but exhibit bright emission when they aggregate, which open a new avenue for the practical applications. Due to the flexible and rotor structure of AIEgens, the aggregate structure of AIEgens is highly sensitive to the surrounding microenvironment, resulting in adjustable optical properties. Fibers integrated of a multiplicity of functional components are ideal carriers to control the aggregation processes, further assembly of fibers produces large‐scale fabrics with amplified functions and practical values. In this Concept article, we focus on the latest advances on the synergy between “AIE+Fiber” for the boosted performance that beyond AIE, and their applications are presented and abstracted out to stimulate new ideas for developing “AIE+Fiber” systems.
Dynamic Covalent Optical Chirality Sensing with a Sterically Encumbered Aminoborane
Authors: De los Santos Zeus A. , Lynch Ciarán C. , Wolf Christian 
Published: July 2022

AbstractA sterically encumbered aminoborane sensor is introduced and used for quantitative stereochemical analysis of monoalcohols, diols and amino alcohols. The small‐molecule probe exhibits a rigid ortho‐substituted arene scaffold with a proximate boron binding site and a triarylamine circular dichroism (CD) reporter unit which proved to be crucial for the observed chiroptical signal induction. Coordination of the chiral target molecule produces strong Cotton effects and UV changes that are readily correlated to its absolute configuration, enantiomeric composition and concentration to achieve comprehensive stereochemical analysis within a 5 % absolute error margin. The sensing method was successfully applied in the chromatography‐free analysis of less than one milligram of a crude asymmetric reaction mixture and the advantages of this chiroptical sensing approach, which is amenable to high‐throughput experimentation equipment and automation, over traditional methods is discussed.
Estimation and fault diagnosis for non‐linear system with time‐varying faults and measurement noises: Application on two CSTRs in series
Authors: Bzioui Sana , Channa Rafik 
Published: July 2022

AbstractA continuously stirred tank reactor (CSTR) is largely used in water treatment and in chemical and biological processes. It is characterized by a complex non‐linear behaviour. Operating large reactors in industry can be expensive, so a common trick used to reduce costs is to operate multiple CSTRs in series. Consequently, the CSTR is usually exposed to faults and noises. This paper addresses the design of a robust observer for estimation and fault diagnosis strategy on two CSTRs in series. The considered system is affected simultaneously by time‐varying actuator and sensor faults with measurement noises. The Takagi‐Sugeno multimodel approach is proposed to transform the non‐linear model into an interpolation of several linear sub‐models with non‐measurable premise variables. The purpose of this brief is to provide the state and the fault estimation for the considered system using a proportional multiple integral (PMI) unknown input observer. The exponential stability conditions are studied with the Lyapunov theory and L2 optimization and formulated in terms of linear matrix inequalities. In addition, a comparative study with a PMI observer is conducted. Finally, the proposed observer is used for time‐varying fault detection and isolation.

Published: July 2022

AbstractTransthyretin amyloid cardiomyopathy (ATTR‐CM) is a debilitating and life‐threatening condition with a heterogeneous clinical presentation. Recent guidelines from the United States and Europe have been published to guide clinical practice and to facilitate management conformity by covering current diagnostic and treatment strategies for patients with ATTR‐CM. These guidelines highlight the importance of an early diagnosis to optimize therapeutic outcomes, specifying the use of tests and imaging techniques to allow accurate, noninvasive diagnosis of ATTR‐CM. However, as regional practice variations across Asia may limit access to healthcare, availability of specific tests, and expertise in assessing diagnostic images, there is an ongoing need to provide an Asian perspective on these clinical guidelines. This review article provides practical recommendations for the diagnosis and monitoring of patients with ATTR‐CM in Asia, highlighting the need for additional guidelines to support a broad and diverse population, consider differing healthcare systems and diagnostic testing availability, and provide a flexible yet robust algorithm.

Published: July 2022

AbstractPulsed Field Gradient (PFG) NMR is recognised as an analytical technique used to characterise the tortuosity of porous media by measurement of the self‐diffusion coefficient of a fluid contained within the pore space of the material of interest. Such measurements are usually performed on high magnetic field NMR hardware (>300 MHz). However, many materials of interest, in particular heterogeneous catalysts, contain significant amounts of paramagnetic species, which make such measurements impossible due to their characteristic short spin‐spin relaxation times. Here it is demonstrated that by performing PFG NMR measurements on a low field magnet (2 MHz), tortuosity measurements can be obtained for a range of titania (TiO2) based carriers and catalyst precursors containing paramagnetic species up to a 20 wt.% loading. The approach is also used to compare the tortuosity of two catalyst precursors of the same metal loading prepared by different methods.
Time‐Dependent Growth Rates of TGA‐Capped ZnS Nanocrystals as a Synthetic Formula for Ligand‐Capped Quantum Dots
Authors: Bui Tan Phuc , Nguyen Thanh Phuong 
Published: July 2022

AbstractZnS quantum dots (ZnS QDs) are prepared in the absence and presence of thioglycolic acid (TGA) molecules by using a chemical precipitation method. The as‐prepared ZnS QDs are characterized by photoluminescence (PL), UV–vis absorption, Fourier transform infrared (FTIR), and X‐ray powder diffraction (XRD). Based on the calculation from XRD patterns, the temporal evolution of ZnS‐TGA QD size is fashioned and is in agreement with the Ostwald ripening process. The temporal evolution of ZnS–TGA QD size is divided into two regimes and two approximate expressions of growth time (t) − average size (d) ast= Ad3+ B andt= Cd2+ D (A, B, C, D are constants) for lower and higher values oftare suggested, respectively. The growth rates are large in the lower regime and are near zero in the higher regime. The time value at the frontier of these regimes is revealed as the necessary time to synthesize ZnS–TGA QDs. Under the experimental conditions, this value is 60 min (corresponding size of 1.80 nm). This study paves the way for determining the fabrication time of ligand‐capped quantum dots.
Do foreign chief executive officers spend more on corporate social responsibility in Vietnam?
Authors: Adomako Samuel , Tran Mai Dong 
Published: July 2022

AbstractDespite the burgeoning studies on corporate social responsibility, little is known about the influence of chief executive officer (CEO) foreignness on a firm's corporate social responsibility (CSR) expenditure. This study investigated the effect of foreign CEOs on CSR expenditure of local firms in Vietnam. In addition, we examined the moderating roles of firm reputation and customer demandingness on foreign CEO‐CSR expenditure relationship. Results from data collected from 167 local firms in Vietnam indicate that CEO foreignness positively influences CSR expenditure. The results also revealed that greater levels of firm reputation and demanding customers moderate the effect of CEO foreignness and CSR expenditure. Implications for CSR scholarship and practice are discussed.
The impact of discrimination on binge eating in a nationally representative sample of Latine individuals
Authors: Johnson Sarah N. , Forbush Kelsie T. , Swanson Trevor James 
Published: July 2022

AbstractObjectiveLatines have higher rates of eating disorders characterized by binge eating compared to their non‐Latine white counterparts, yet culturally and socially relevant factors related to binge eating in Latines have been largely understudied. The purpose of the current study was to examine how discrimination and acculturative stress were associated with binge eating in a nationally representative sample of Latines. An additional aim was to test the extent to which family cohesion and social support could buffer against the effects of discrimination and acculturative stress on binge eating.MethodParticipants (56% female, N = 2550) were Latines enrolled in the National Latino and Asian American Study. Structural equation modeling using 1000 re‐sampled data sets built from machine learning iterative sampling procedures was used to examine the effects of discrimination, acculturative stress, family cohesion, and social support on binge eating.ResultsResults indicated that only discrimination was significantly associated with binge eating. Neither the direct effect of acculturative stress, interaction of family cohesion and acculturative stress, interaction of social cohesion and acculturative stress, nor the interaction of social support and discrimination were significantly associated with binge eating.DiscussionThis study highlights the need for mental‐health providers to understand and assess discrimination among Latines presenting with concerns of binge eating. Treatments that effectively provide coping strategies to manage discriminatory experiences and reduce binge eating could improve both effectiveness of treatment and retention rates for Latine individuals with binge eating.Public SignificanceThis study examined the association of discrimination, acculturative stress, family cohesion, and social support with binge eating in Latines. Only discrimination was significantly associated with binge eating, highlighting the importance for providers to assess discrimination among Latines with binge‐eating concerns and to improve equity, inclusion, and belonging at a societal level. Modifying existing treatments to address coping with discrimination could improve the effectiveness for Latines with binge‐eating concerns.
Do plant communities show constant final yield?

Published: July 2022

AbstractTotal biomass production of plant monocultures growing over a range of densities and harvested after a period of growth increases monotonically with density and then levels out at higher densities. This pattern is called constant final yield (CFY) and is considered one of the most general phenomena in plant ecology. If CFY applies to plant communities, it would be a key to understanding and predicting many community‐level phenomena. We tested two primary hypotheses experimentally: (1) Mixtures of several species show CFY. (2) If so, the proportion of biomass production by the component species in a mixture does not change at densities above the density that reaches CFY. We performed a series of glasshouse experiments over 3 years using a “community density series,” in which the overall density of five species was varied while their proportions remained unchanged. In the first experiment, we grew a mixture of annual and perennial herbaceous species in mesocosms, and all species were also grown in monocultures at the corresponding densities. A similar experiment was performed in the second and third years, but only with annuals. A third experiment with mixtures only was performed in pots over 2 years. In all cases, aboveground biomass was harvested, separated by species, dried, and weighed. Perennials with underground storage organs produced maximum aboveground biomass at low or intermediate densities. In the second experiment, two of the species produced maximum biomass at the second‐highest density in monoculture, while mixtures of all five species showed classical CFY behavior, and the contribution of the species to the mixture changed very little above the lowest density producing CFY. The results of the third experiment were also consistent with the hypotheses. In conclusion, CFY in aboveground biomass production was observed in communities of annual species, and the contribution of the individual species was relatively insensitive to an increase in density above that reaching CFY, i.e., competitive performance of the species changed with density until CFY was reached. Evidence for CFY was stronger in mixture than in monoculture. Coexistence theory must include density as well as frequency dependence if densities are below CFY.
