AbstractObjectiveA childhood cancer diagnosis is a traumatic experience for patients and their families. However, little is known about the effect on grandparents. We aimed to investigate the negative psychosocial impact, coping strategies, and positive outcomes of grandparents of childhood cancer patients in Switzerland.MethodsWe collected data using a semi‐structured interview guide and applied qualitative content analysis.ResultsWe conducted 20 interviews with 23 grandparents (57% female; mean age = 66.9 years; SD = 6.4; range = 57.0–82.4) of 13 affected children (69% female; mean age = 7.5 years; SD = 6.1; range = 1.0–18.9) between January 2022 and April 2023. The mean time since diagnosis was 1.0 years (SD = 0.5; range = 0.4–1.9). Grandparents were in shock and experienced strong feelings of fear and helplessness. They were particularly afraid of a relapse or late effects. The worst part for most was seeing their grandchild suffer. Many stated that their fear was always present which could lead to tension and sleep problems. To cope with these negative experiences, the grandparents used internal and external strategies, such as accepting the illness or talking to their spouse and friends. Some grandparents also reported positive outcomes, such as getting emotionally closer to family members and appreciating things that had previously been taken for granted.ConclusionsGrandparents suffer greatly when their grandchild is diagnosed with cancer. Encouragingly, most grandparents also reported coping strategies and positive outcomes despite the challenges. Promoting coping strategies and providing appropriate resources could reduce the psychological burden of grandparents and strengthen the whole family system.

Societal impact statementGlobal yam production is centred on West Africa, but there are significant knowledge gaps about farm‐level diversity across much of the region, and especially in Guinea. Although yam production is increasing in Guinea, in the longer term, varietal diversity and the sustainability of agri‐systems are at risk. Documentation of local crop diversity is essential as a baseline to understand trajectories of past and future varietal loss. This study utilises interdisciplinary approaches, which are needed to help understand the ways historic crop diversity is created and maintained within indigenous agricultural and food heritage systems, as well as the reasons for its loss over time.Summary
Yams are important staple foods in many tropical and sub‐Saharan countries. The ‘yam belt’ extends from Guinea to western central Africa. However, yam cultivation is comparatively little researched or documented in Guinea, and the country is commonly not included within descriptions of key yam growing areas in Africa.
Our study utilises ethnobotanic methods and plant specimen collections to fill these gaps in West African yam research. Interviews with over 70 farmers from six villages across the Kankan region of Guinea provide information on yam cultivation and diversity, and changes in living memory over the past 40 years. We present the analyses of ethnobotanical data from Haute‐Guinée on yam cuisine, and commercialisation, and on changes to the range of varieties grown over time.
The annual cycle of indigenous yam agri‐systems remains a key part of rural life, food systems and economy. However, interviews revealed dramatic temporal changes over the last 40 years. Although yam production has increased, a narrow range of commercial cultivars is currently displacing the historically‐rooted local diversity.
The expansion of yam cultivation is regarded locally as having relied on a shift to more unsustainable and extensive land use, and with herbicides and chemical fertilisers replacing intensive organic soil management. This has implications for research and development in sub‐Saharan agriculture for yams and other important native West African crops in the future.

AbstractBACKGROUNDIn pesticide research, bleaching herbicides have always been a hot topic. Our previous research showed that N‐(4‐fluorobenzyl)‐2‐methoxybenzamide is an innovative lead compound for bleaching herbicides.RESULTSA total of 40 derivatives of picolinamides were prepared and evaluated for their herbicidal activity by Petri dish tests and postemergence trials. The structure–activity relationship (SAR) revealed that introducing electron‐withdrawing groups at the 3‐ or 4‐positions of the benzyl significantly enhances herbicidal activity. Furthermore, ZI‐04 induced similar symptoms such as bleaching effect in treated weeds and accumulation of biosynthetic precursors for carotenoids as observed with diflufenican. ZI‐04 also exhibited significant cross‐resistance to diflufenican and had a lower resistance risk than diflufenican.CONCLUSIONN‐benzyl‐6‐methylpicolinamides were discovered as a novel scaffold for bleaching herbicides. The accumulation of phytoene, phytofluene and ζ‐Carotene in radish cotyledons, and cross‐resistance observed with diflufenican, showed that title compounds can interfere with carotenoid biosynthesis. © 2024 Society of Chemical Industry.
Tight interval state estimate for discrete‐time descriptor linear systems
Authors: Lamouchi Rihab , Meslem Nacim , Raïssi Tarek 
Published: February 2024

SummaryIn this work, two state estimation methods are proposed for a class of discrete‐time descriptor linear systems subject to bounded uncertainties. First, we propose set‐valued estimator algorithm using symmetric boxes to compute rigorous bounds of the system states. The observer gains are calculated using norm to attenuate the effects of the uncertainties and to improve the accuracy of the proposed estimator. Second, to obtain tighter state enclosures, zonotopic set computation are developed instead of interval analysis to design a new set‐valued state estimation algorithm. The performances of the proposed state estimation approaches are highlighted on different illustrative examples.

AbstractCornelian cherry (CC) is a source of bioactive compounds such as phenolics, melatonin and, vitamin C and used as traditional food and in folk medicine. In this study, we analyzed and compared the variation of some bioactive compounds and antioxidant capacity in CC fruits depending on ripening and genotype. CC fruit was sampled at different ripening times (unripe, semi‐ripe and ripe) and the contents of sugars, vitamin C, melatonin and phenolic compounds were analysed by ultra‐fast liquid chromatography (UFLC‐PDA). The results showed that the fruits at the unripe samples had a significantly higher chemical components and antioxidant capacity. Chlorogenic acid, catechin, gallic acid and rutin were the four major phenolic compounds identified in all genotypes. Melatonin concentration of unripe fruits was found to be high in all genotypes (ranged from 1664.78–114.60 ng/mL) and a decrease was detected in ripe fruits. Significant increases in vitamin C and individual sugar contents (glucose and fructose) occurred with advancing maturity. The highest vitamin C concentration was determined as 77.38 mg/100 g during the full ripening period. Antioxidant capacity results determined by both methods showed a decreasing tendency with the ripening of the fruits. Concerning antioxidant activity, DPPH and ABTS scavenging activity were maximal at unripe in all CC genotpes. During the development and maturity periods of fruits, important physiological and biochemical changes occured that affect antioxidant capacity, nutritional and chemical composition.

AbstractThe study investigated antioxidant biomarkers in Dreissena polymorpha to evaluate the efficiency of Fenton process (FP) in Organized Industrial Zone Wastewater (OIZW) treatment. Antioxidant enzymatic activities, including superoxide dismutase (SOD) and catalase (CAT), glutathione peroxidase (GPX), non‐enzymatic antioxidants (GSH) and the indicator of lipid peroxidation (TBARS) were measured in D. polymorpha in response to treated OIZW by FP. The performance of the FP has been optimized with response surface methodology (RSM). The optimum conditions (reaction time, and H2O2 and Fe2+ concentration) for OIZW by the FP process were determined. The results showed that the highest COD removal efficiency (83.94 %) was obtained when as Fe2+ concentration=402.35 mg/L, H2O2 concentration=4100.30 mg/L, and reaction time=10.10 min (desirability=1.000). SOD and CAT enzyme was decreased in the 1/25 diluted OIZW group compared to control group. CAT and SOD enzyme activities were increased after treatment compared to control groups. No statistically significant changes were observed in GSH levels and GPx activities. TBARS levels were increased 1/25 diluted OIZW exposure groups compared to the control group. TBARS levels were decreased after treatment. The results revealed that antioxidant parameters are useful biomarkers for determining the treatment efficiency of the FP.

AbstractA new approach for synthesizing selenylated naphthalene derivatives is described herein, employing trichloroisocyanuric acid (TCCA) as the oxidizing agent. The developed protocol yielded 18 compounds, with yields ranging from 32 % to 90 %. Additionally, the reaction was conducted under mild conditions, utilizing ethanol as the solvent at room temperature, demonstrating good atom economy. The key aspect of the protocol is the in situ generation of electrophilic selenium species through the reaction of diorganyl diselenides and TCCA.
Product digitization and differentiation strategy change: Evidence from the book publishing industry
Authors: Miller Cameron D. , Wang Richard D. 
Published: February 2024

AbstractResearch SummaryWe study product digitization as an impetus for firm strategy change. Product digitization can erode a firm's ability to differentiate through physical product attributes and prompts them to increase emphasis on nonphysical product attributes to sustain their competitive advantage. We expect this effect is pronounced among firms that have pursued a physical differentiation strategy prior to the digital age. However, we expect that countervailing forces exist such that the internal supply cost of and the external market demand for the nonphysical differentiator mitigate this effect. Evidence from publishers in the Amazon Kindle e‐book ecosystem supports our hypotheses. This study bridges the growing digital strategy literature and the classical competitive strategy literature. We discuss how our findings are relevant to a range of industries.Managerial SummaryMany companies invest in superior physical product attributes to increase a customer's willingness‐to‐pay and entice purchase. However, when products become digitized—such as music streaming displacing CDs or e‐books replacing printed books—the effectiveness of physical product differentiation is diminished. We examine how book publishers manage this challenge at the advent of Amazon's Kindle e‐book technology. We find that publishers that have emphasized physical product attributes turn to emphasizing nonphysical product differentiation, namely, through offering more content. Yet, the extent of the strategy change is limited by the internal development cost of and the external demand for the nonphysical differentiator. We discuss how our findings are relevant to a range of settings, including both product and service companies.
Optimizing Iodine Enrichment through Induced‐Fit Transformations in a Flexible Ag(I)‐Organic Framework: From Accelerated Adsorption Kinetics to Record‐High Storage Density

Published: February 2024

AbstractEfficient capture and storage of radioactive I2 is a prerequisite for developing nuclear power but remains a challenge. Here, two flexible Ag‐MOFs (FJI‐H39 and 40) with similar active sites but different pore sizes and flexibility are prepared; both of them can capture I2 with excellent removal efficiencies and high adsorption capacities. Due to the more flexible pores, FJI‐H39 not only possesses the record‐high I2 storage density among all the reported MOFs but also displays a very fast adsorption kinetic (124 times faster than FJI‐H40), while their desorption kinetics are comparable. Mechanistic studies show that FJI‐H39 can undergo induced‐fit transformations continuously (first contraction then expansion), making the adsorbed iodine species enrich near the Ag(I) nodes quickly and orderly, from discrete I− anion to the dense packing of various iodine species, achieving the very fast adsorption kinetic and the record‐high storage density simultaneously. However, no significant structural transformations caused by the adsorbed iodine are observed in FJI‐H40. In addition, FJI‐H39 has excellent stability/recyclability/obtainability, making it a practical adsorbent for radioactive I2. This work provides a useful method for synthesizing practical radioactive I2 adsorbents.

AbstractCharging LiCoO2 to high voltages yields alluring specific capacities, yet the deleterious phase‐transitions lead to significant capacity degradation. Herein, this study demonstrates a novel strategy to stabilize LiCoO2 at 4.6 V by doping with Er and Mg at the Li‐site and Co‐site, respectively, which is different from the traditional method of doping foreign elements solely at the Co‐site. Theoretical calculations and experiments jointly reveal that the inclusion of Mg2+‐dopants at the Co‐site curbs the hexagonal‐monoclinic phase transitions ≈4.2 V. However, this unintentionally compromises the stability of lattice oxygen in LiCoO2, exacerbating the undesired phase transition (O3 to H1‐3) above 4.45 V. Fascinatingly, the introduction of Er3+‐dopants into Li‐sites enhances the stability of lattice oxygen in LiCoO2, effectively mitigating phase transitions above 4.45 V. Therefore, the Er, Mg co‐doped LiCoO2 exhibits high stability over 500 cycles when tested in a half‐cell with a cut‐off voltage of 4.6 V. Furthermore, the Er, Mg‐doped LiCoO2//graphite pouch‐type full cell demonstrates a high energy density of 310.8 Wh kg−1, preserving 91.3% of its energy over 100 cycles.

Published: February 2024

AbstractModern strides in energy storage underscore the significance of all‐solid‐state batteries (ASSBs) predicated on solid electrolytes and lithium (Li) metal anodes in response to the demand for safer batteries. Nonetheless, ASSBs are often beleaguered by non‐uniform Li deposition during cycling, leading to compromised cell performance from internal short circuits and hindered charge transfer. In this study, the concept of “bottom deposition” is introduced to stabilize metal deposition based on the lithiophilic current collector and a protective layer composed of a polymeric binder and carbon black. The bottom deposition, wherein Li plating ensues between the protective layer and the current collector, circumvents internal short circuits and facilitates uniform volumetric changes of Li. The prepared functional binder for the protective layer presents outstanding mechanical robustness and adhesive properties, which can withstand the volume expansion caused by metal growth. Furthermore, its excellent ion transfer properties promote uniform Li bottom deposition even under a current density of 6 mA·cm−2. Also, scanning electron microscopy analysis reveals a consistent plating/stripping morphology of Li after cycling. Consequently, the proposed system exhibits enhanced electrochemical performance when assessed within the ASSB framework, operating under a configuration marked by a high Li utilization rate reliant on an ultrathin Li.

AbstractAs a fundamental product of CO2 conversion through two‐electron transfer, CO is used to produce numerous chemicals and fuels with high efficiency, which has broad application prospects. In this work, it has successfully optimized catalytic activity by fabricating an electrocatalyst featuring crystalline‐amorphous CoO‐InOx interfaces, thereby significantly expediting CO production. The 1.21%CoO‐InOx consists of randomly dispersed CoO crystalline particles among amorphous InOx nanoribbons. In contrast to the same‐phase structure, the unique CoO‐InOx heterostructure provides plentiful reactive crystalline‐amorphous interfacial sites. The Faradaic efficiency of CO (FECO) can reach up to 95.67% with a current density of 61.72 mA cm−2 in a typical H‐cell using MeCN containing 0.5 M 1‐Butyl‐3‐methylimidazolium hexafluorophosphate ([Bmim]PF6) as the electrolyte. Comprehensive experiments indicate that CoO‐InOx interfaces with optimization of charge transfer enhance the double‐layer capacitance and CO2 adsorption capacity. Theoretical calculations further reveal that the regulating of the electronic structure at interfacial sites not only optimizes the Gibbs free energy of *COOH intermediate formation but also inhibits HER, resulting in high selectivity toward CO.

AbstractBackgroundTranscutaneous point‐shear wave elastography (p‐SWE) performed using an acoustic radiation force impulse can be used to quantify pancreatic stiffness in chronic pancreatitis (CP). We aimed to evaluate its usefulness to diagnose and monitor CP.Methods175 participants were included in this prospective study including patients with CP (n = 65), liver cirrhosis (LC; n = 60), alcohol abuse (n = 10) and healthy controls (n = 40). Point‐shear wave elastography of the pancreas was performed and quantified as median shear wave velocity (SWV). In the same way, p‐SWE of the spleen served as a marker of portal hypertension. The M‐ANNHEIM Severity score was used as global marker for disease activity in CP.ResultsCompared to healthy controls, pancreatic SWV was significantly elevated in CP (1.38 vs. 0.96 m/s; p < 0.0001, MWU‐test). Pancreatic SWV was increased in alcoholic CP but not in hereditary CP. Receiver operating characteristic analysis revealed 1.2 m/s as the optimal cut‐off to identify non‐heredity‐CP subjects (90% specificity; 81% sensitivity; 92% positive predictive value). Pancreatic SWV correlated significantly with the M‐ANNHEIM Severity score, severity of CP‐typical complications (both p < 0.05, linear regression analysis), morphological changes of the pancreas and need for hospital treatment (both p < 0.05, MWU‐test) but not with exocrine or endocrine insufficiency. Pancreatic SWV >1.7 m/s was identified to predict M‐ANNHEIM Severity score ≥11 points. Pancreatic SWV was also elevated in LC (1.42 m/s; p < 0.001), correlating with increased splenic SWV.ConclusionTranscutaneous pancreatic p‐SWE represents a bedside, cost‐effective and non‐invasive tool which adds valuable information to the process of diagnosing and monitoring CP. By portal hypertension, an increased pancreatic SWV must be expected.

Published: February 2024

AbstractWood‐plastic composites are green composites made of plastic as the matrix and wood as the filler; however, the incompatibility between these two leads to the degradation of the composites. This paper reports the synthesis of a novel bio‐based compatibilizer, annotated as OA‐g‐H20, by grafting oleic acid (OA) on a hyperbranched polyester (Boltorn H20). The effect of modifying recycled polypropylene‐based wood–plastic composites with this compatibilizer was then assessed. The Fourier transform infrared spectroscopy, thermogravimetric analysis, and gel permeation chromatography techniques were employed to characterize the fabricated OA‐g‐H20, while its modification effect was assessed by differential scanning calorimetry, dynamic thermomechanical analysis, scanning electron microscopy, and mechanical property tests. The experimental results revealed that the optimal addition amount of OA‐g‐H20 was 2.0 wt.%.Highlights
