AbstractAn electrochemical sensor based on carbon quantum dots@hexagonal boron nitride nanosheets nanocomposites (CQDs@HBNNS‐NCs) and molecularly imprinted polymer (MIP) was proposed for the triclosan (TCS) analysis. The CQDs@HBNNS‐NCs were utilized as the modifier, which exhibited excellent electrochemical properties. The MIP film was prepared in situ in the presence of template (TCS) and monomer (o‐phenylenediamine) to provide the specific molecular recognition. The CQDs@HBNNS‐NCs were characterized by transmission electron microscopy (TEM), X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FT‐IR), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Under the optimal conditions, the current response was linear with the logarithmic value of TCS concentration in the range of 2 nM–0.1 mM, and the limit of detection (LOD) was calculated as 0.005 μM (S/N=3). Furthermore, the proposed electrochemical sensor showed favorable selectivity, stability, and was used for the TCS analysis in tap water samples with decent accuracy.

AbstractTo clarify the mechanism of active site conversion and utilization of the Pt−M alloy complexed with nitrogen‐doped carbon (NC) catalysts (Pt−M/NC) for oxygen reduction reaction (ORR), we synthesized the two‐dimensions thin‐layer hierarchical porous nitrogen‐carbon for supporting PtCo nanoparticles (2D PtCo/TNC) and applied to alkaline ORR. The self‐assembled thin layer of carbon nitride (TL‐C3N4) was thermally fused with commercial carbon black (C) to form a 2D‐TNC, which can conduct the optimal mass transfer. Therewith, PtCo nanoparticles were anchored on this carrier through a thermal injection strategy, promoting the formation of Co−N and achieving low Pt loading (2 wt%). As a promoter, the Co−N favours the lattice distortion of PtCo alloys and facilitates the in‐situ adsorption‐diffusion process of oxygen‐containing species. Thus, the obtained catalyst demonstrates an excellent ORR activity in alkaline electrolytes, with a half‐wave potential (E1/2) of 0.885 V and electrochemical active surface area (ECSA) of 111 m2/g, lower Tafel slope of 66 mV/dec.

AbstractC2‐symmetric terpene‐based bis(α‐amine oximes) prepared from monoterpene hydrocarbons (+)‐3‐carene, (−)‐α‐pinene and (+)‐limonene, when treated with methylene chloride under phase‐transfer conditions, undergo inter‐ and intramolecular cross‐linking at oxime groups to form D2‐symmetric macrocycles in relatively good preparative yields (35–64 %). The structure of the new compounds was solved by spectroscopic methods and proved by X‐ray crystallography. D2‐symmetric macrocycles are crystalline solids which are well soluble even in small amounts of low‐polar organic solvents. Using Microwave Plasma Atomic Emission Spectrometry the new compounds was found to be able to selectively extract some noble metals (PtIV, AuIII, PdII) from aqueous solutions with pH=1.2 containing complex mixtures of transition elements at with no noticeable extraction of d‐elements (CrVI, MnII, FeIII, CoII, NiII, CuII, ZnII) and other noble metals (RuIII, RhIII, IrIII).
In‐situ Electrochemical Activation Enhances the OER Catalytic Performance of Ag NWs@ZIF‐67 in Alkaline Simulated Seawater

Published: June 2022

AbstractModification of MOFs by in‐situ electrochemical activation is a simple and convenient way. Two dimenstional Zeolitic Imidazolate Framework‐67 (the following is abbreviated as 2D‐ZIF 67) nanosheets were grown on the surface of silver nanowires using a bottom‐up concentration‐controlled method. Due to the inductive effect of the solvent, the nanosheets grow in the direction favorable for the OER catalytic reaction, so the material exhibits an overpotential of 250 mV in both alkaline aqueous solution and alkaline simulated seawater at a current density of 10 mA.cm−2, not subject to CER competition. After in‐situ electrochemical activation in alkaline simulated seawater, oxygen vacancies and reactive sites were generated on the surface of the composites by the synergistic effect of current and electrolyte. Under the same effect, AgCl@Co(OH)2 heterogeneous interface were formed between the Ag nanowires and 2D‐ZIF67 nanosheets. As a result, the OER catalytic performance was further improved, and the overpotential was only 222 mV in alkaline simulated seawater.

AbstractAlthough imine metathesis has been extensively studied, how to take imine metathesis as a new way to generate racemates has never been achieved. In this work, it is the first report that chiral imines, such as (S)‐1 and (R)‐2 or (R)‐1 and (S)‐2, were used to produce two pairs of racemates via imine metathesis, when the metathesis reaction reaches its equilibrium state, in the presence of catalytic amounts of the amine employed to synthesize the corresponding chiral imines.

Published: June 2022

AbstractThe Peritraumatic Distress Inventory (PDI) is a well‐known self‐report questionnaire indexing the distress experienced during and shortly after a most stressful or traumatic event. Although sociodemographic factors contributing to peritraumatic distress have been previously investigated, no research has examined the nature and severity of peritraumatic distress reactions in a non‐clinical, community sample as a function of age. An international sample of 5621 adult participants were grouped according the World Health Organization's age stratification protocol. Mean scores and item endorsement on the PDI were compared across groups with respect to their worst experience of the COVID‐19 pandemic. A significant between‐group difference was found, F(55,615) = 30.74, p < 0.001, n2 = 0.027 whereby participants aged 18–39 years old reported the highest levels of peritraumatic distress. This group also endorsed a higher proportion of items on the PDI's two main factors (emotional distress and physical reactions), and were more likely to endorse feelings of helplessness, than older participants. It appears that severity of peritraumatic distress during the pandemic has affected younger people the most. Results are discussed in light of clinical implications.

AbstractRupture of tendons and ligaments (T/L) is a major clinical challenge due to T/L possess anisotropic mechanical properties and hierarchical structures. Here, to imitate these characteristics, an approach is presented by fabricating hybrid nanofibrous composites. First, hybrid fiber‐reinforced yarns are fabricated via successively electrospinning poly(L‑lactide‑co‑ε‑caprolactone) (PLCL) and gelatin (Ge) nanofibers onto polyethylene terephthalate (PET) fibers to improve biodurability and biocompatibility. Then, by comparing different manufacturing methods, the knitted structure succeeds in simulating anisotropic mechanical properties, even being stronger than natural ligaments, and possessing comfort compliance superior to clinically used ligament advanced reinforcement system (LARS) ligament. Moreover, after inoculation with tendon‐derived stem cells and transplantation in vivo, hybrid nanofibrous composites are integrated with native tendons to guide surrounding tissue ingrowth due to the highly interconnected and porous structure. The knitted hybrid nanofibrous composites are also ligamentized and remodeled in vivo to promote tendon regeneration. Specifically, after the use of optimized anisotropic hybrid nanofibrous composites to repair tendon, the deposition of tendon‐associated extracellular matrix proteins is more significant. Thus, this study indicates a strategy of manufacturing anisotropic hybrid nanofibrous composites with superior mechanical properties and good histocompatibility for clinical reconstruction.

Hyperthermia in a Chow Chow under general anaesthesia for magnetic resonance imaging
Authors: Jones Heather , Robson Katherine 
Published: June 2022

AbstractA 5‐year 7‐month‐old, entire, male Chow Chow presented with paraparesis and ataxia due to a previously diagnosed T11–T12 spinal diverticulum. Due to the progression of clinical signs, magnetic resonance imaging was indicated to reassess the lesion. Preoperative rectal temperature was unable to be assessed due to temperament; however, it was likely the patient would be hyperthermic as it had been hyperthermic (40.6°C) under general anaesthesia 4 months earlier. Consequently, measures were taken to attempt to reduce body temperature before general anaesthesia. While under general anaesthesia for imaging, the patient was confirmed to be markedly hyperthermic. This report details the management of a patient with hyperthermia under general anaesthesia. The patient was gradually cooled before recovery from anaesthesia. Once recovered from anaesthesia and normothermic, the patient was discharged home the same day. Follow‐up confirmed no adverse effects.
No evidence of a prospective relationship between serum zinc and venous thromboembolism in Caucasian men: a cohort study
Authors: Kunutsor Setor K. , Jae Sae Young , Laukkanen Jari A. 
Published: June 2022

AbstractSerum zinc has been implicated as an important mediator of haemostasis and thrombosis. However, the nature and magnitude of any potential relationship between serum zinc and venous thromboembolism (VTE) is unknown. We aimed to evaluate the prospective association between serum zinc and VTE risk. We analyzed data involving 2472 men aged 42–61 years without a history of VTE in the Kuopio Ischemic Heart Disease population-based cohort study, with the assessment of serum zinc concentrations using atomic absorption spectrometry. Hazard ratios (95% confidence intervals [CIs]) for incident VTE were estimated. A total of 166 VTE cases occurred during a median follow-up of 27.1 years. The risk of VTE per 1 standard deviation increase in serum zinc in analysis adjusted for systolic blood pressure, body mass index, total cholesterol, triglycerides, smoking status, histories of type 2 diabetes and coronary heart disease, medication for dyslipidaemia, alcohol consumption, physical activity, and socioeconomic status was (HR 1.03; 95% CI 0.86–1.22), which remained similar (HR 1.04; 95% CI 0.87–1.23) following further adjustment for inflammation and history of cancer. Comparing the extreme tertiles of serum zinc, the corresponding adjusted HRs (95% CIs) were 0.92 (0.63–1.36) and 0.94 (0.64–1.39), respectively. Imputed results based on 2682 participants and 176 VTE events were consistent with the observed results. In middle-aged and older Finnish men, serum zinc is not associated with future VTE risk. Other large-scale prospective studies conducted in other populations are needed to confirm or refute these findings.
Exploring the social implications of buying and selling cyber security
Authors: Harkin Diarmaid , Molnar Adam 
Published: June 2022

AbstractGovernments, businesses, private citizens and even organised crime are increasingly investing in cyber security, with the cyber security industry growing in size and relevance. This paper demonstrates that markets for the buying and selling of cyber security should be subject to many of the same critical inquiries typically targeted at the private security industry. Using a number of illustrative examples of emerging trends in the commodification of cyber security it will be highlighted how these markets create significant social impacts and present similar dilemmas of democracy, justice, sovereignty, and deleterious side-effects for wider society. Key conceptual differences between cyber security commodities and ‘conventional’ security commodities will also be considered before arguing for an inter-disciplinary research agenda into the considerable social implications of the buying and selling of cyber security commodities.
Photonic Crystal Resonator in the Millimeter/Terahertz Range as a Thin Film Sensor for Future Biosensor Applications

Published: June 2022

Abstract
With recent developments, terahertz (THz) technology has attracted great interest in many different fields of research and application. In particular, biosensors that detect a thin film of captured pathogens are in high demand for rapid diagnosis. Based on the interaction between analytes under test and electromagnetic (EM) field, THz resonators are sensitive to changes in the permittivity of the analyte and have the potential to become sensitive thin-film sensors. However, conventional metamaterial methods have low Q factors, leading to small amplitude variations and ambiguous detection. Here, we present a photonic crystal (PhC)–based resonator with a high Q factor that is sensitive to a monolayer of beads in the µm size range. The PhC resonator made of high resistivity silicon (HRSi) shows a Q factor of 750, which is much higher compared to metamaterial-based methods. Its resonance shift is linearly related to the coverage of the micron-sized beads on its surface. Moreover, simulation results with a thin film model of a single layer of the beads showed agreement with the experimental results. Although the achieved sensitivity needs to be improved by enhancing the field concentration on the analyte, our results suggest that THz PhC resonators with high Q factor are promising for biosensing applications. We anticipate our work to be a starting point for biochips with improved sensing capabilities and more functionality.
When Happiness is Both Joy and Purpose: The Complexity of the Pursuit of Happiness and Well-Being is Related to Actual Well-Being
Authors: Krasko Julia , Intelisano Sabrina , Luhmann Maike 
Published: June 2022

AbstractPeople differ in how they define and pursue happiness and well-being (HWB). Previous studies suggested that the best way to achieve a high level of well-being might be to pursue different facets of HWB simultaneously. We expand on this idea and introduce the concept of complexity of HWB definitions to describe how many HWB definitions people endorse simultaneously, and the complexity of HWB-related intentions to describe how many unique facets of HWB people intend to pursue in everyday life. To operationalize these novel concepts, we developed two parallel measures that integrate psychological and philosophical definitions of HWB. In two independent studies (total N = 542), exploratory and confirmatory factor analyses revealed eight reliable and valid factors for both parallel scales: absence of negativity, positive attitude, tranquility, personal development, luck, joy and desires, purpose, and belonging. Complexity of HWB-related intentions was positively associated with all facets of well-being, whereas complexity of HWB definitions was only positively associated with some facets of well-being. HWB-related intentions and their complexity emerged as more important for the experience of well-being than HWB definitions and their complexity. These studies highlight the importance of a multifaceted conceptualization of HWB when investigating how the pursuit of HWB is related to actual levels of well-being.
Improving the Stability of the Variable Selection with Small Datasets in Classification and Regression Tasks
Authors: Cateni Silvia , Colla Valentina , Vannucci Marco 
Published: June 2022

AbstractWithin the design of a machine learning-based solution for classification or regression problems, variable selection techniques are often applied to identify the input variables, which mainly affect the considered target. The selection of such variables provides very interesting advantages, such as lower complexity of the model and of the learning algorithm, reduction of computational time and improvement of performances. Moreover, variable selection is useful to gain a profound knowledge of the considered problem. High correlation in variables often produces multiple subsets of equally optimal variables, which makes the traditional method of variable selection unstable, leading to instability and reducing the confidence of selected variables. Stability identifies the reproducibility power of the variable selection method. Therefore, having a high stability is as important as the high precision of the developed model. The paper presents an automatic procedure for variable selection in classification (binary and multi-class) and regression tasks, which provides an optimal stability index without requiring any a priori information on data. The proposed approach has been tested on different small datasets, which are unstable by nature, and has achieved satisfactory results.
Rate constants of chlorine atom reactions with organic molecules in aqueous solutions, an overview

Published: June 2022

AbstractRate constants of chlorine atom (Cl•) reactions (kCl•) determined using a large variation of experimental methods, including transient measurements, steady-state and computation techniques, were collected from the literature and were discussed together with the reaction mechanisms. The kCl• values are generally in the 108–109 mol−1 dm3 s−1 range when the basic reaction between the Cl• and the target molecule is H-atom abstraction. When Cl• addition to double bonds dominates the interaction, the kCl• values are in the 1 × 109–2 × 1010 mol−1 dm3 s−1 range. In the kCl• = 1 × 1010–4 × 1010 mol−1 dm3 s−1 range, single-electron-transfer reactions may also contribute to the mechanism. The Cl• reactions with organic molecules in many respects are similar to those of •OH, albeit Cl• seems to be less selective as •OH. However, there is an important difference, as opposed to Cl• in the case of •OH single-electron-transfer reactions have minor importance. The uncertainty of Cl• rate constant determinations is much higher than those of •OH. Since Cl• reactions play very important role in the emerging UV/chlorine water purification technology, some standardization of the rate constant measuring techniques and more kCl• measurements are recommended.

Abstract
Spinocerebellar ataxia type 7 (SCA7) and other polyglutamine (polyQ) diseases are caused by expansions of polyQ repeats in disease-specific proteins. Aggregation of the polyQ proteins resulting in various forms of cellular stress, that could induce the stress granule (SG) response, is believed to be a common pathological mechanism in these disorders. SGs can contribute to cell survival but have also been suggested to exacerbate disease pathology by seeding protein aggregation. In this study, we show that two SG-related proteins, TDP-43 and TIA1, are sequestered into the aggregates formed by polyQ-expanded ATXN7 in SCA7 cells. Interestingly, mutant ATXN7 also localises to induced SGs, and this association altered the shape of the SGs. In spite of this, neither the ability to induce nor to disassemble SGs, in response to arsenite stress induction or relief, was affected in SCA7 cells. Moreover, we could not observe any change in the number of ATXN7 aggregates per cell following SG induction, although a small, non-significant, increase in total aggregated ATXN7 material could be detected using filter trap. However, mutant ATXN7 expression in itself increased the speckling of the SG-nucleating protein G3BP1 and the SG response. Taken together, our results indicate that the SG response is induced, and although some key modulators of SGs show altered behaviour, the dynamics of SGs appear normal in the presence of mutant ATXN7.
The socioeconomic factors of investment-induced petroleum consumption: case of fast developing Chinese economy

Published: June 2022

AbstractCapital investment stimulates a sizable portion of petroleum consumption, especially in emerging economies. However, investment-embedded petroleum consumption (IEPC) and the socioeconomic factors that influence it are not well studied. Our study's objective is to close this research gap. Our article estimates the effects of petroleum intensity, technology, investment structure, and economic development on China's IEPC using input–output and bipolar structural decomposition analysis. Additionally, our article develops a previously mostly unknown index of investment intensity. The findings indicated that, on average, between 1990 and 2016, investment induced nearly 30% of China's total final demand-embedded petroleum consumption. On average, petroleum intensity had the most significant decreasing effect on the Chinese IEPC. Averagely, technology had a positive impact, but from 2010 to 2016, it had a noticeable negative impact (− 1.51 exajoule). Both investment intensity and economic development had a significant upward effect. The impact of investment intensity was the smallest of all the factors. Disaggregation of the effects of socio-economic factors at the sectoral level revealed distinct patterns. Thus, by focusing on the socioeconomic dynamics of key sectors, the factors' current decreasing effects can be maximized, and their increasing effects minimized.
