AbstractIn this paper, the multisignal (different emissions/colours) temperature sensing of NaYF4:Eu3+ nanoparticles is investigated, which is based on fluorescence intensity ratios (FIRs) between 5D0→7FJ (J=1‐4) and 5D1→7FJ’ emissions. The 5D1→7FJ’ (J'=0‐2) emissions can be clearly observed due to the low photon energy of NaYF4. Based on the FIRs between different 5D0→7FJ and 5D1→7FJ’ emissions, higher absolute/relative temperature sensitivities are obtained. Compared with the FIR between whole 5D0→7FJ and 5D1→7FJ’ emissions, the maximum value of Sa was improved from 0.27 K−1 to 5.02 K−1 and that of Sr was improved from 0.89%·K−1 to 1.27%·K−1. Furthermore, the FIRs between different colours of emissions were investigated for the application of wide‐range multicolour temperature sensing.

AbstractBackgroundPericardiocentesis is undertaken in patients with cancer for diagnostic and therapeutic purposes. However, there are limited data on the frequency, characteristics and mortality of patients with different cancers undergoing pericardiocentesis.MethodsAll hospitalisations of adult cancer patients (≥18 years) in the US National Inpatient Sample between January 2004 and December 2017 were included. The cohort was stratified by discharge code of pericardiocentesis and cancer, using the International Classification of Diseases. The prevalence of pericardiocentesis, patient characteristics, cancer types and in‐hospital all‐cause mortality were analysed between cancer patients undergoing pericardiocentesis versus not.ResultsA total of 19,773,597 weighted cancer discharges were analysed, out of which 18,847 (0.1%) underwent pericardiocentesis. The most common cancer types amongst the patients receiving pericardiocentesis were lung (51.3%), haematological (15.9%), breast (5.4%), mediastinum/heart (3.2%), gastroesophageal (2.2%) and female genital cancer (1.8%), whilst ‘other’ cancer types were present in 20.2% patients. Patients undergoing pericardiocentesis had significantly higher mortality (15.6% vs. 4.2%, p < 0.001) compared to their counterparts. The presence of metastatic disease (aOR 2.67 95% CI 1.79–3.97), weight loss (aOR 1.48 95% CI 1.33–1.65) and coagulopathy (aOR 3.22 95% CI 1.63–6.37) were each independently associated with higher mortality in patients who underwent pericardiocentesis.ConclusionPericardiocentesis is an infrequent procedure in cancer patients and is most commonly performed in patients with lung, haematological and breast cancer. Cancer patients undergoing pericardiocentesis have increased mortality, irrespective of the underlying cancer type.

AbstractIn 2019 four groups reported independently the development of a simplified enzymatic access to the diphosphates (IPP and DMAPP) of isopentenol and dimethylallyl alcohol (IOH and DMAOH). The former are the two universal precursors of all terpenes. We report here on an improved version of what we call the terpene mini‐path as well as its use in enzymatic cascades in combination with various transferases. The goal of this study is to demonstrate the in vitro utility of the TMP in, i) synthesizing various natural terpenes, ii) revealing the product selectivity of an unknown terpene synthase, or iii) generating unnatural cyclobutylated terpenes.

Authors: Fritsche Raphael F. , Schuh Tristan , Kataeva Olga , Knölker Hans‐Joachim 
Published: October 2022

AbstractWe describe an iron‐catalyzed asymmetric oxidative C−C coupling of diarylamines which proceeds at room temperature with air as final oxidant. Using hexadecafluorophthalocyanine‐iron(II) as catalyst in the presence of catalytic amounts of an axially chiral biaryl phosphoric acid, the resulting chiral 2,2′‐diamino‐1,1′‐biaryls are obtained in up to 90 % ee as confirmed by chiral HPLC. A detailed mechanism has been proposed with a radical cation‐chiral phosphate ion pair as key intermediate leading to the observed asymmetric induction.

Authors: Acheli Sonia , Weers Martin , Wollmann Annett , Weber Alfred P. 
Published: October 2022

AbstractDer Trennprozess im Abweiseradsichter wurde in der Vergangenheit intensiv untersucht, das dynamische Verhalten aber noch nicht. Das Erreichen des stationären Zustandes kann mehrere zehn Minuten dauern. Zwischen der Zufuhr des Pulvers und dem Abfluss über Fein‐ und Grobgutstrom bildet sich ein Holdup aus. In dieser Studie wurde die Dynamik eines Abweiseradsichters beim Anfahren und beim Materialwechsel untersucht. Die charakteristischen Zeiten sind stark von der Feed‐Beladung und weniger von der Drehzahl abhängig. Für hohe Drehzahlen sind die charakteristischen Zeiten beider Prozesse vergleichbar.

AbstractIntroductionCardiovascular diseases are very common in the general population, and several factors play a role in their development. The purpose of this study was to investigate the relationship between hyperuricaemia and other cardiovascular disease risk factors.MethodsThis cross‐sectional study was conducted on 1008 people over the 15‐year‐old general population in Kerman, Iran. The blood samples of all patients were analysed for the uric acid serum level, and they completed a checklist including physical activity, previous history of hypertension and diabetes, smoking and opium.ResultsA number of 1008 cases of people were entered into the study. According to the results of this study, 254 patients had uric acid levels above the 75th percentile (6 mg/dl in males, and 5 mg/dl in females). No significant difference was observed between gender (p = .249) and age groups (p = .125) of people with and without hyperuricaemia. The prevalence of overweight/obesity (p < .001), hypertension (p = .004) and low physical activity (p = .033) was significantly higher in patients with hyperuricaemia. The duration of hypertension was significantly higher in hyperuricaemic individuals (p = .022). Overweight/obesity (OR = 2.67; 95% CI = 1.87–3.82) and hypertension (OR = 1.40; 95% CI = 1.02–1.93) were two significant independent factors that contributed to the increased risk of hyperuricaemia in the subjects.ConclusionThe uric acid serum level is higher in people with hypertension and overweight/obesity. Hyperuricaemia increases the risk of cardiovascular events, which can be prevented by determining the appropriate strategy for the early diagnosis and treatment of this metabolic disorder.

AbstractIn this study, a novel strategy to amplify electrochemical signals by mesoporous PdPt nanoparticles with core‐shell structures anchored on a three‐dimensional PANI@CNTs network as nanozyme labels (PdPt/PANI@CNTs) was proposed for the sensitive monitoring of α‐fetoprotein (AFP, Ag). First, the mesoporous PdPt nanoparticles prepared by a facile chemical reduction method had excellent biocompatibility with biomolecules, which could capture a large amount of AFP‐Ab2 (Ab2) and exhibit plentiful pores to entrap more thionine (Thi) into mesoporous PdPt nanoparticles with enhanced loading and abundant active sites. Furthermore, the resulting mesoporous PdPt nanoparticles were abundantly dotted on the surface of a three‐dimensional PANI@CNTs network with excellent conductivity and a high specific surface area through the bonding of the amino group to form PdPt/PANI@CNTs nanozyme labels. Most importantly, the as‐prepared PdPt/PANI@CNTs nanozyme labels exhibited unexpected enzyme‐like activity towards the reduction of hydrogen peroxide owing to the highly indexed facets, enhancing the current response to realize signal amplification. In view of the advantages of nanozyme labels and the involvement of gold nanoparticles (AuNPs, which behave as electrode materials) for the sensitive determination of AFP, the as‐developed immunosensor could obtain a dynamic working range of 0.001 ng mL−1–100.0 ng mL−1 at a detection limit of 0.33 pg mL−1 via DPV (at 3σ). Furthermore, the nanozyme‐based electrochemical immunosensor exhibited remarkable analytical performance, which brought about feasible ideas for disease diagnosis in the future.

Published: October 2022

AbstractLGBTQ+ stories and histories have long been silenced as part of deliberate work by those in power to erase our identities and experiences. As evaluators, we contribute to the process of either silencing or uplifting LGBTQ+ stories. This aspect of our work begs a number of vital questions that each of us must reckon with when we approach an evaluation: What data are necessary to allow us to tell a story? What story will we tell with the data we have collected? And, most importantly, who does the telling of certain stories benefit, who might it harm, and what is our responsibility as evaluators to protect peoples’ stories? Proceeding from these questions, this chapter has three distinct parts. In Part One, we establish a common language. By integrating perspectives from the social sciences and LGBTQ+ community scholarship, we provide an overview of the complex and contextually specific nature of sex, sexual orientation, and gender, and discuss the implications of these complexities on how we approach collecting LGBTQ+ data. In Part Two, we consider the power of the stories we tell to impact the lives of LGBTQ+ people, and the frameworks, theories, and ethical imperatives which may help us to contribute to a narrative of LGBTQ+ liberation through our work. Finally, in Part Three, we offer an example tool for readers to use as they consider how they would approach this work in their own practices.
Mentalizing strategies for navigating the social world in adolescence
Authors: Guazzelli Williamson Victoria , Mills Kathryn L. 
Published: October 2022

AbstractMentalizing—the ability to represent or infer the mental states of others—continues to develop into and throughout adolescence. Increased mentalizing sophistication during adolescence is thought to support the navigation of increasingly complex social relationships and contexts. However, developmental science has yet to aggregate the seemingly disparate findings from research relating mentalizing to functional outcomes, such as internalizing mental health concerns, into clear and comprehensive theories that explain individual variability during adolescence. In this review, we describe approaches that have been used to measure mentalizing during adolescence and propose a methodological framework to measure mentalizing as a multi‐dimensional process that continues to develop as a response to the environment during adolescence.

Published: October 2022

AbstractThe Belt and Road Initiative (BRI) intends to enhance China's international integration, strikingly by enhancing infrastructure and bolstering trade and investment links among the economies involved. Poor transport infrastructure and border restrictions are significant deterrents to trade expansion, economic growth, and bilateral trade. Using panel structural gravity model estimations, this study investigates the impact of Transportation infrastructure inheritances on bilateral trade across the Belt and Road member countries, particularly in Eastern Africa. The study considers the potential effect of the BRI roads, railways, and Information and Communication Technology (ICT) infrastructure network on the bilateral trade and economies of the Eastern African countries. The empirical analysis offers robust evidence that transport infrastructure promotes trade. The study found that transport infrastructure has a significant and positive effect on trade. These results imply that transport infrastructure exerts a strong effect on trade and growth in Eastern Africa. Policies for increasing access and affordability of transport infrastructure are highly recommended to promote trade and economic growth in the Eastern Africa sub‐region.

Published: October 2022

AbstractBackgroundAerobic granular sludge (AGS) has emerged as a novel wastewater treatment technology and as a suppressing alternative to conventional activated sludge. The development of mathematical models of the AGS process, which can be used for wastewater treatment plant (WWTP) design and optimization, is therefore necessary to support successful implementation of AGS technology. This study aims to develop a zero‐dimensional (0D) AGS model that can be used in engineering practice for the above‐mentioned purposes.ResultsA laboratory AGS sequencing batch reactor (SBR), removing soluble organic substrate, nitrogen and phosphorus, was fed with artificial wastewater and modelled using a 0D approach. Model development was supported by bacterial characterization using 16S rRNA gene amplicon high‐throughput sequencing. The mathematical model was based on the activated sludge model no. 2d (ASM2d) and extended with both two‐step nitrification as implemented in the wastewater treatment plant simulator Sumo19 (Dynamita SARL) and ammonia nitrogen adsorption and desorption according to the Langmuir model. The variations of ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, orthophosphate phosphorus and dissolved oxygen concentrations during one cycle of the SBR were successfully reproduced by the model (all Pearson's r values ≥0.93 and all r2 ≥ 0.86).ConclusionsThe 0D modelling approach was proven to be applicable to AGS. It is possible that the 0D approach can fill the gap that has developed between engineering and research in the biofilm modelling community. The 0D modelling approach therefore merits further exploration using reactors fed with real wastewater, as well as on pilot and full‐scale WWTPs. © 2022 Society of Chemical Industry (SCI).

AbstractThere is currently an unprecedented number of forcibly displaced people worldwide. Little is known, however, about how external stressors and internal coping strategies intersect to influence mental health in displaced refugees, particularly whether specific types of coping strategies are more or less effective across different levels of external stress. This study aimed to understand whether positive and negative internal coping strategies were differentially associated with mental health across high and low levels of external stressors in displaced refugees. Participants were 1,216 refugees living in Indonesia who completed an online survey indexing demographic characteristics, exposure to ongoing stressors, positive psychological coping strategies (i.e., cognitive flexibility, self‐efficacy, and hope), negative psychological coping strategies (i.e., rumination and intolerance of uncertainty), psychological symptoms (i.e., posttraumatic stress disorder, depression, and anxiety) and mental health‐related quality of life. Participants (27.3% female, Mage = 30.52 years) were from Arabic‐, Farsi‐, Tamil‐, Somali‐, Dari‐, and English‐speaking backgrounds. Results of latent moderated structural equation modeling indicated that the association between negative psychological coping strategies and poorer mental health was stronger at higher levels of stress, whereas the association between positive psychological coping strategies and better quality of life was stronger at lower levels of stress. These findings provide evidence in support of tailored approaches that integrate interventions addressing external stressors and internal coping strategies to support positive mental health and enhanced quality of life in displaced refugees.
Furanoate Polyesters/Polylactide/Reduced Graphene Oxide Nanocomposite Films: Thermomechanical and Gas Permeation Properties

Published: October 2022

AbstractThis work aims at preparing bioderived polymer films by blending poly(lactic) acid (PLA) and poly(dodecylene 2,5‐furandicarboxylate) (PDoF) and containing reduced graphene oxide (rGO) as a multifunctional filler in variable weight fraction (from 0.25 to 2 phr). Although the PLA/PDoF blend results as immiscible, the addition of rGO leads to smaller (from 2.6 to 1.6 µm) and more irregularly shaped PDoF domains and to a better PLA/PDoF interfacial adhesion, which suggests that rGO may act as a blend compatibilizer. Dynamic mechanical thermal analysis (DMTA) shows that rGO shifts the glass transition of PDoF (≈5°C) to higher temperatures. The addition of 10 wt% PDoF in PLA increases the strain at break (+145%), and the addition of 0.25 phr of rGO to this blend increases its tensile strength (+13%), without significantly modifying the strain at break. Finally, rGO strongly decreases the diffusivity and permeability to O2, N2, and CO2 due to an increased diffusion path for gas molecules. These results highlight the positive and sometimes synergistic role of PDoF and rGO in tuning the thermomechanical and gas permeation properties of PLA.

Published: October 2022

AbstractCarbonaceous nanofillers, namely carbon nanotubes (CNT) and graphene‐based nanoparticles (GNP), have truly attractive physical and mechanical properties such as high elastic modulus, as well as noteworthy thermal and electrical conductivities. This has inevitably stimulated a growing interest toward the development of CNT and GNP‐based composites with improved mechanical and electrical properties for application in aeronautics, aerospace, automotive, nautical, and in general, infrastructural field. In this context, understanding the rheological behavior of nanocomposites loaded with one‐dimensional (1D) and bi‐dimensional (2D) carbon fillers is crucial for optimizing the manufacturing process of carbon fiber reinforced panels (CFRPs) and for obtaining information on whether the structure is percolated. This study demonstrates the special ability of the analyzed systems to guarantee good rheological properties, thus confirming their applicability as structural materials in a wide temperature range.

Published: October 2022

AbstractThe dynamics of two model glass‐formers (three‐dimensional [3D] oligomer melt and two‐dimensional [2D] polydisperse colloidal system) are analyzed using MD simulations. It is found that the standard deviation of the shear modulus shows a striking peak near the glass transition Tg, which is explained with a quantitative theory. The simulation data well below Tg suggest that static multi‐point correlations of local stress are long‐range. The obtained correlation functions of time‐dependent and wavevector‐resolved stress for the 2D system are in excellent agreement with the developed theory indicating that the frozen‐in stress inhomogeneities in the glassy state are correlated according to a power law.

Published: October 2022

AbstractAdditive manufacturing (AM) is a niche process that has seen extensive growth and adoption in the past decade in the industrial sector. Among the AM techniques present on the market today there are identified only a few methods allowing the 3D printing of metallic materials to be of special interest for their applications in various domains like the automotive, aeronautical, and healthcare industries. The most important questions needing answers are how to produce components from metallic materials that have superior qualities like versatility, wear resistance, ease of customization, and ease of integration with existing components. Compared to traditional metalworking methods where it has been studied how the metal behaves and morphs during the process and where it is known exactly what to do in order to modify the properties of the resulting component into a favor metal, AM changes everything, forcing a researcher to start from the beginning. While the technology is starting to be used more and more, the need to find production methods leads to consistent quality products and with outstanding material properties. New methods need to be developed to help attune the properties of the 3D printed parts to the requirements of their respective uses. The present study refers to 3D metal additive manufacturing (MAM), providing an overview on the process itself and its possible results as well as hurdles with added methods to overcome them.
