AbstractRechargeable aqueous Zn batteries (RAZBs) are highly promising for grid‐scale energy storage systems. Nevertheless, strong water molecule adsorption on Zn electrode provokes undesired corrosion reactions and electrode polarization/dendrite growth, restricting the reversibility of Zn anode and the commercialization of RAZBs. Herein, ethylenediamine tetraacetic acid (EDTA), a typical compounding ingredient, was applied in aqueous ZnSO4 electrolyte to replace the adsorbed water molecules on Zn surface and enabled a stable complexation adsorbent interface. The chemically adsorbed EDTA layer reduced the direct contact between H2O molecules and metallic Zn, and reduced the corrosion rate to more than a half. Moreover, such adsorbent interface featuring abundant oxygen/nitrogen‐based functional groups regulated Zn deposition kinetics and promoted the uniform Zn plating. As consequence, the stable complexation adsorbent interface enabled highly‐reversible Zn stripping/plating behavior for 5000 h under a harsh dynamic measurement that combining eletrochemical cycling at 1 mA cm−2 and 0.5 mAh cm−2 for 72 h and resting for 24 h. The effectiveness of such complexation adsorbent interface was also verified in MnO2||Zn full cells. The complexation interface chemistry demonstrated in this study opened up new avenues for the design of low‐cost and highly reversible Zn metal electrodes towards next‐generation RAZBs.

Published: January 2022

AbstractDesalination of seawater with zero‐liquid discharge is a major challenge. Here we developed a three‐dimensional “umbrella” architecture to evaporate hypersaline brines of up to 20 wt% using solar‐driven interfacial evaporation. By controlling the water pathway and the thickness of the evaporator films to manipulate the salt capacitance of the system, a stable evaporation rate of >2.6 kg m−2 h−1 was achieved over 4‐day operation in the laboratory environment with minimized salt accumulation on evaporation surfaces. By placing the system in an outdoor environment with natural wind, the peak evaporation rate was improved to 9.05 kg m−2 h−1. After a 4‐day outdoor test, the total evaporated water by the umbrella system was 3.7× more than the natural evaporation from a bulk water surface under identical environmental conditions. The predesigned water flow also controlled the local salt accumulation, resulting in easier salt removing and collection, which is highly desired for accelerated salt mining applications.image

Published: January 2022

AbstractPendant polymer‐based organic electrodes consisting of redox‐active quinones are promising for the next generation of rechargeable batteries owing to their fast redox kinetics and the structural diversity of their design. Many commercially available norbornene monomers have been popular choices for preparing pendant polymer electrodes, since these monomers enable numerous synthetic routes for attaching redox‐active pendant groups. However, these electrodes often suffer from sluggish lithium‐ion mobility at both the electrode–electrolyte interface and within the bulk of the electrode because of their poor ionic conductivity. This can lead to low cycling stability and rate capability. In this study, we design and compare the performance of redox‐active poly(norbornene) and poly(oxanorbornene) pendant polymer electrodes. The additional oxygen in the repeat unit of poly(oxanorbornene) facilitates conduction of Li‐ions, resulting in improved performance relative to their poly(norbornene) counterparts. Specifically, higher reversible capacities are achieved at high current densities and initial capacity is better retained during prolonged cycling tests. Unlike previous strategies to increase the ionic conductivity of polymer electrodes, our design involves minimal synthetic steps and only contributes to a small increase in additional redox‐inactive mass, offering a versatile platform for high‐performance organic electrode materials.image

Published: January 2022

AbstractThe financial status of high‐tech startups directly reflects a country's economic vitality. Hence, the financial distress of high‐tech startups will hinder a country's economic growth. In this study, we extract financial data of seven countries from the VICO 2.0 dataset; the sample includes high‐tech startups (labeled as acquired, nonacquired, failure, and nonfailure) between 2005 and 2014. We utilize seven algorithms in machine learning to identify critical variables that predict financial distress of high‐tech startups in the European Union (EU), thereby preventing high‐tech startup failure or acquisition. Specifically, our experimental results also thoroughly verify the seven countries' economic situation after the 2008 economic crisis. Overall, this work can provide sufficient financial risk warnings for creditors, investors, and managers and support businesses from each countries' commercial sectors.

Abstract
Hibiscus rosa‐sinensis and Zingiber officinalis teas are traditionally used for the therapies of various diseases, including obesity. The present research work was planned to appraise the potential of polyphenol‐rich extracts of selected herbal plants in obesity and related biochemical parameters of high‐fat–sugar diet‐induced obese rats. Three herbal teas were prepared from Hibiscus rosa‐sinensis flowers and Zingiber officinalis rhizomes and their mixture (3:1, respectively). Total phenolic contents (TPC) of Hibiscus rosa‐sinensis and Zingiber officinalis extracts were found to be 5.82 and 1.45 mg/g of dry plant material, measured as GAE, while total flavonoid contents (TFC) were 9.17 and 1.95 mg/g of dry plant material, measured as CE, respectively. Two doses (250 and 500 mg/kg BW) of each tea were administered and body weight, BMI, kidney, liver, and atherogenic indices, TC, TG, HDL, LDL, VLDL, BT, AST, ALT, AP, SC, MDA, SOD, GSH, and TAC of rats groups were measured. Data showed that higher doses of Hibiscus rosa‐sinensis significantly reduced the rat's BMI (0.50 g/cm2) in comparison with the high‐fat–sugar diet group (0.79 g/cm2). All treatment groups, especially H‐500 group, showed a significant decrease in the elevated kidney and liver weights and atherogenic index in comparison with HFSDC groups. Higher doses of Hibiscus rosa‐sinensis significantly decreased the levels of AST, ALT, AP, and SC in comparison with the HFSDC group. A significant decrease in the levels of serum TC, TG, LDL, and VLDL was observed in all the treatment groups in comparison with the HFSDC group. Furthermore, all the teas, especially higher doses of Hibiscus rosa‐sinensis, prevented the alterations in MDA, SOD, and GSH levels of experimental groups, thus showing the potential against oxidative stress. It can be concluded from these results that Hibiscus rosa‐sinensis teas exhibited strong protective effects against obesity and oxidative stress, especially at higher doses.
Value of open data: A geoscience perspective
Authors: Wildman Geraldine , Lewis Edward 
Published: January 2022

AbstractWe are living in a data‐centric society, with governments and businesses increasingly looking at what they can do to gain insight and improve the flow of data. Encouraging the release of data as ‘open data’ is one measure that would remove barriers to access, increase use and facilitate downstream data innovation. Using examples from firstly the non‐geoscience and then geoscience sectors, this paper outlines three factors that can lead to a successful open data programme. These are (1) having a clear strategy with a well‐articulated vision; (2) ensuring that data are not only free but also technically accessible and delivered under an open licence; and (3) continued investment in the programme to ensure its long‐term success. However, not all data can or should be open, and organizations and governments must be careful that their interventions do not have unintended consequences that might reduce incentives to collect, maintain and share data. A primary concern is the financial sustainability of a dataset, but this also extends to other risks that would prevent the data being widely shared such as the inclusion of personal data or third‐party intellectual property. In these cases, use of a data‐sharing risk assessment framework, and the application of the FAIR principles of findable, accessible, interoperable and reusable can be used to increase data sharing and maximize the benefits that can be realized from geoscience data.
Origin of bimodal rear‐arc volcanism, Trans‐Mexican Volcanic Belt eastern sector: Geochemical and isotopic evidence from the Quaternary Xihuingo‐La Paila Volcanic Field
Authors: Martínez‐Serrano Raymundo G. , Valadez‐Cabrera Sac‐Nicté , Roberge Julie , Cristiani‐Solís Carlos G. 
Published: January 2022

The Quaternary Xihuingo‐La Paila Volcanic Field comprises basalts and basaltic andesites (0.8–0.5 Ma) that built many scoria cones, shield volcanoes, and contemporaneous (~0.4 Ma) dacitic dome structures, emplaced in the rear‐arc area of the Trans‐Mexican Volcanic Belt eastern sector. Most basalts and basaltic andesites exhibit LILE/HFS ratios related to subduction processes. Nevertheless, some basaltic cones are alkaline in composition, with trace‐element patterns that indicate an enriched mantle source, but Ba and Pb positive anomalies are also present. Although dacitic rocks also display typical trace‐element patterns for subduction settings, a simple magmatic liquid line of descent cannot relate the basalts to dacites. The Sr and Nd isotopic values (87Sr/86Sr = 0.70399 to 0.70522 and εNd = +0.25 to +4.80) for felsic and mafic rocks suggest a small interaction of magmas with continental crust components, and the Pb isotopic ratios (206Pb/204Pb = 18.68–18.78; 207Pb/204Pb = 15.58–15.63 and 208Pb/204Pb = 38.44–38.62) show that all volcanic products form a mixing line between a mantle‐like component and a radiogenic component like the Palaeozoic Acatlán complex. A slab rollback process probably produced the magmatic migration of the volcanic front to the Middle American trench during the Late Miocene–Quaternary, which favoured the ascent of the asthenosphere to the mantle wedge. Melting of this heterogeneous mantle then produced mafic magmas that intruded the lower continental crust, and dacitic products could be formed by the partial melting of these mafic intrusions emplaced by frequent injections at the base of the continental crust.

Published: January 2022

AbstractIntroductionMissed appointments are a major health issue in the healthcare systems globally. They directly impact on the use of hospital resources, patient's health, and can lead to patient's dissatisfaction. This study was conducted to assess the reasons for missing a hospital appointment.MethodsA survey was conducted with a randomly selected sample of patients who missed their outpatient appointment in Royal hospital, Sultanate of Oman, from March to April 2021 in six clinics. Patients were interviewed via telephone to answer a structured survey. In addition, a self‐administered survey was distributed to medical staff to explore their perspectives.ResultsTwo hundred eighty patients and 52 medical staff participated in the study. Frequent patient‐reported reasons for missed appointment were transportation difficulties (11.4%), no longer needing (7.5%), or forgetting the appointment (6.8%); staff‐reported reasons were transportation (23.8%), no SMS received (16.9%), and forgetting the appointment (15.4%). Frequencies of reasons varied substantially between clinics. Family obligations were the main theme in obstetrics (odds ratio [OR] 9.48; 95% confidence interval [CI] 2.66‐33.78) and in diabetes clinic (OR 10.55; 95% CI 2.68‐38.58), where transportation issue was the main theme in Oncology clinic (OR 4.83; 95% CI 1.11‐21.02). The recommendations for improvement were mainly around improving the reminder system, the use of telephone reminders, and developing a flexible appointment scheduling system.ConclusionKnowing the reasons for missed appointment from patients and health professionals can help to develop effective interventions. The heterogeneity between clinics in reasons for missed appointment indicates for interventions tailored to clinic and frequent reasons.

AbstractObjectiveTo estimate the prevalence of women who were admitted to health facilities with abortion‐related complications who reported feeling anxious/stressed during their stay, and to identify sociodemographic, facility, and abortion‐related characteristics associated with self‐reported experience of anxiety/stress.MethodsWe used data from four countries in Eastern and Southern Africa (Kenya, Malawi, Mozambique, and Uganda) collected from 2017–2018 as part of the World Health Organization (WHO) Multi‐Country Survey on Abortion‐related morbidity (MCS‐A). Information was extracted from women's medical records and their participation in audio computer‐assisted self‐interviews (ACASI). Based on a question in the ACASI, “Did you encounter any anxiety or stress during your hospital stay?”, the percentage of women who self‐reported feeling anxious/stressed during their facility stay was calculated. Generalized estimating equations were used to identify the determinants of anxiety/stress following a hierarchical approach whereby potential determinants were grouped from most distal to most proximal and analyzed accordingly.ResultsThere were 1254 women with abortion‐related complications included in the analysis, of which 56.5% self‐reported that they felt anxious/stressed during their facility stay. We found evidence that lower socioeconomic status, lower levels of education, no previous childbirth, no previous abortion, higher gestational age at abortion, and use of unsafe methods of abortion were independent determinants of self‐reporting anxiety/stress.ConclusionsAction should be taken to reduce experience of anxiety/stress among women attending facilities for postabortion complications, including reducing the number of women experiencing abortion‐related complications by improving access to safe abortion. This issue warrants further study using more comprehensive and validated tools to understand the levels and drivers of anxiety/stress self‐reported by women attending facilities with abortion‐related complications.
Dynamic association of flavin cofactors to regulate flavoprotein function
Authors: Schnerwitzki Danny , Vabulas R. Martin 
Published: January 2022

AbstractFlavoproteins are key players in numerous redox pathways in cells. Flavin cofactors FMN and FAD confer the required chemical reactivity to flavoenzymes. In most cases, the interaction between the proteins and the flavins is noncovalent, yet stronger in comparison to other redox‐active cofactors, such as NADH and NADPH. The association is considered static, but this view has started to change with the recent discovery of the dynamic association of flavins and flavoenzymes. Six cases from different organisms and various metabolic pathways are discussed here. The available mechanistic details span the range from rudimentary, as in the case of the ER‐resident oxidoreductase Ero1, to comprehensive, as for the bacterial respiratory complex I. The same holds true in regard to the assumed functional role of the dynamic association presented here. More work is needed to clarify the structural and functional determinants of the known examples. Identification of new cases will help to appreciate the generality of the new principle of intracellular flavoenzyme regulation.

AbstractCachexia is a syndrome characterized by involuntary weight loss and wasting of skeletal muscle mass. It is associated with worse overall survival and quality of life. The cancer‐induced systemic inflammation and the consequent host derived catabolic stimuli, trigger cachexia by inhibiting muscle protein synthesis and enhancing muscle catabolism. The muscle itself may further promote chronic inflammation, introducing a vicious catabolic circle. Nutritional support alone plays a limited role in the treatment of cancer cachexia and should be combined with other interventions. Physical exercise lowers systemic inflammation and promotes muscle anabolism. It also attenuates the age‐related physical decline in elderly and it might counteract the muscle wasting induced by the cancer cachexia syndrome. This review describes how cancer‐induced systemic inflammation promotes muscle wasting and whether physical exercise may represent a suitable treatment for cancer‐induced cachexia, particularly in patients with non‐small cell lung cancer. We summarized pre‐clinical and clinical studies investigating whether physical exercise would improve muscle performance and whether this improvement would translate in a clinically meaningful benefit for patients with cancer, in terms of survival and quality of life. Moreover, this review describes the results of studies investigating the interplay between physical exercise and the immune system, including the role of the intestinal microbiota.

Published: January 2022

AbstractWe report two patients with PMM2‐CDG who developed end stage renal disease (ESRD). Renal abnormalities of clinical significance have only been reported in about 6% of patients with PMM2‐CDG and have rarely been reported as the cause of death. Given the recurrent episodes of acute kidney injury associated with hospital admissions and the accelerated development of ESRD thereafter in our two patients, we recommend proactively involving Nephrology early in the care of these patients.

AbstractIn this study, neutral loss scan and high‐resolution MS/MS were used in combination to detect and tentatively identify various flavonoid and limonoid glycosides in navel orange albedo, juice, peel and pulp. These compound classes are of research interest due to their flavour and bioactive properties, and although flavonoid glycosides have been previously studied in other food matrices, to the best of our knowledge, neutral loss scans have not been used for the elucidation of limonoid glycosides. Neutral loss masses of 120, 162 and 308 Da were selected for the detection of hexose, rutinose and neohesperidose‐substituted flavonoids, whereas 197 Da was explored for limonoid glycosides due to their tendency to form ammonium adducts. Fragmentation patterns obtained from targeted MS/MS were then used to differentiate rutinose and neohesperidose substituents as well as flavonoid subclasses of flavones, flavanones and flavonols. Additionally, high‐resolution MS/MS was also used for the identification of aglycones by accurate mass (to four decimal places), allowing for the differentiation of aglycones with similar unit masses but different chemical formulas. In total, 19 flavonoid glycosides and six limonoid glycosides were detected. This workflow allows for a rapid screening of flavonoid and limonoid glycosides in citrus, which can be further extended to other food products such as tea.
