Abstract3D organic‐inorganic metal halide perovskites are excellent materials for optoelectronic applications due to their exceptional properties, solution processability, and cost‐effectiveness. However, the lack of environmental stability highly restricts them from practical applications. Herein, a stable centimeter‐long 2D hybrid perovskite (N‐MPDA)[PbBr4] single crystal using divalent N1‐methylpropane‐1,3‐diammonium (N‐MPDA) cation as an organic spacer, is reported. The as‐grown single crystal exhibits stable optoelectronic performance, low threshold random lasing, and multi‐photon luminescence/multi‐harmonic generation. A photoconductive device fabricated using (N‐MPDA)[PbBr4] single crystal exhibits an excellent photoresponsivity (≈124 AW−1 at 405 nm) that is ≈4 orders of magnitudes higher than that of monovalent organic spacer‐assisted 2D perovskites, such as (BA)2PbBr4 and (PEA)2PbBr4, and large specific detectivity (≈1012 Jones). As an optical gain media, the (N‐MPDA)[PbBr4] single crystal exhibits a low threshold random lasing (≈6.5 µJ cm−2) with angular dependent narrow linewidth (≈0.1 nm) and high‐quality factor (Q ≈ 2673). Based on these results, the outstanding optoelectronic merits of (N‐MPDA)[PbBr4] single crystal will offer a high‐performance device and act as a dynamic material to construct stable future electronics and optoelectronic‐based applications.

Abstract3D porous Zn‐metal anodes have aroused widespread interest for Zn‐ion batteries (ZIBs). Nevertheless, the notorious “top‐growth” dendrites caused by the intrinsic top‐concentrated ions and randomly distributed electrons may ultimately trigger a cell failure. Herein, an electron/ion‐flux dual‐gradient 3D porous Zn anode is reported for dendrite‐free ZIBs by adopting 3D printing technology. The 3D‐printed Zn anode with layer‐by‐layer bottom‐up attenuating Ag nanoparticles (3DP‐BU@Zn) establishes dual‐gradient electron/ion fluxes, i.e., an internal bottom‐up gradient electron flux created by bottom‐rich conductive Ag nanoparticles, and a gradient ion flux resulting from zincophilic Ag nanoparticles which pump ions toward the bottom. Meanwhile, the 3D‐printing‐enabled hierarchical porous structure and continuously conducting network endow unimpeded electron transfer and ion diffusion among the electrode, dominating a bottom‐preferential Zn deposition behavior. As a result, the 3DP‐BU@Zn symmetrical cell affords highly reversible Zn plating/stripping with an extremely small voltage hysteresis of 17.7 mV and a superior lifespan over 630 h at 1 mA cm−2 and 1 mAh cm−2. Meanwhile, the 3DP‐BU@Zn//VO2 full cell exhibits remarkable cyclic stability over 500 cycles. This unique dual‐gradient strategy sheds light on the roadmap for the next‐generation safe and durable Zn‐metal batteries.

AbstractOwing to their competitive price, ease of processability, and rust resistance, polymers are the most extensively used materials in everyday life. However, consistent exposure to ultraviolet (UV) radiation can lead to the degradation and discoloration of polymeric materials. Various polymer composites containing inorganic and organic nanoparticles (NPs) have been developed to improve the UV‐shielding properties of neat polymers. However, the most used UV‐shielding inorganic NPs are prone to photocatalytic processes, leading to further polymer chain degradation. To overcome this challenge, organic NPs have been used; however, they easily agglomerate, decreasing the UV‐shielding performance of the polymer composites. Herein, we critically report the fundamentals of the UV‐shielding mechanism and the synthesis methods, surface modification, and characterization of the most important inorganic and organic UV‐shielding NPs. We then summarize the various processing techniques used to disperse NPs in polymer matrices to obtain polymer composites with improved UV‐shielding properties. Finally, we propose a broader understanding of how the NP characteristics, their interaction with polymer matrices, and the various processing methods affect the UV‐shielding performance of the obtained polymer composites. In addition, various applications of inorganic and organic NPs‐containing UV‐shielding polymer composites have been reported.
Optimal regulation performance of discrete time‐delay systems based on quantization and input energy constraints

Published: February 2023

AbstractIn this paper, we study the optimal regulation problem of networked control systems and propose a new performance index for a given discrete time‐delay system. The regulation performance of the controlled plant is investigated by considering the effects of various constraints on the communication channel such as quantization, bandwidth, and packet dropouts using frequency domain methods and two‐degree‐of‐freedom control techniques. The results show that the regulation performance is not only related to the location and direction of the non‐minimum phase zeros and unstable poles of a given system but also related to the internal time delay of the controlled plant. Packet dropouts, quantization, and bandwidth limitations can also negatively affect the optimal performance. In addition, the trade‐off of the input energy constraint can also make the optimal regulation performance suffer. Finally, the reliability of this innovative result is illustrated by some simulation examples.

Published: February 2023

AbstractExploring solid electrolytes (SEs) with high ionic conductivity, excellent chemical/electrochemical stability, and excellent compatibility with electrodes is important for promoting the development of all‐solid‐state batteries (ASSBs). Halogen‐rich lithium argyrodite electrolytes have received a lot of attention recently due to their ultrahigh room‐temperature lithium‐ion conductivity and relatively low cost. In this review, the properties of the halogen‐rich argyrodite electrolytes are presented in terms of their crystal structure, ionic conduction mechanism, and compatibilities with oxide cathode and Li‐metal anode. Secondly, the preparation process of SE film and the performances of ASSBs based on this electrolyte are summarized. Finally, the challenges and the next research directions of the electrolytes are proposed. Halogen‐rich lithium argyrodite electrolytes are one of the promising sulfide electrolytes, the collation of this paper can provide us with a better understanding of the current development status of this type of electrolyte and advance their further development.

Published: February 2023

AbstractObjectivesMindfulness may be a helpful tool to enhance psychotherapists' self‐care and intrapersonal skills. To gain deeper knowledge about how to improve mindfulness skills in child and adolescent psychotherapists, we investigated the impact of two mindfulness‐based workshops and a self‐experience interval (individual homework practice of mindfulness exercises) on quantitative and qualitative measures in a nonrandomised study.MethodsThirty‐six trainee psychotherapists took part in the 6‐week workshop‐based mindfulness intervention (experimental group, EG). Twenty‐one trainee psychotherapists served as a comparison group (CG). All participants completed the Kentucky Inventory of Mindfulness Skills (KIMS‐D), the Self‐Compassion Scale (SCS‐D) and the Empathy Scale for Social Workers (ESSW) at pre, post and 6‐month follow‐up. Benefits of the regular use of mindfulness practice of 10 trainee psychotherapists in the EG were analysed using qualitative content analysis at the 6‐month follow‐up.ResultsThe quantitative analyses revealed a significant increase over time on the KIMS‐D subscale “acting with awareness” in both groups and a significant increase over time on the KIMS‐D subscale “accepting without judgment” in the EG in contrast to the CG. The qualitative analyses indicated good acceptance of the mindfulness‐based workshop intervention. Qualitative changes referred to the achievement of knowledge in theory and practice concerning mindfulness and the integration of mindfulness‐based interventions in everyday life.ConclusionThe mindfulness intervention appeared to produce quantitative long‐term changes concerning mindfulness aspects and qualitative changes. Future research should elaborate conditions (i.e., intervention length, intensity and setting) that may influence the manifestation of quantitative and/or qualitative changes in mindfulness‐based workshop interventions in professionals.

Published: February 2023

AbstractDuchenne Muscular Dystrophy (DMD) is an X‐linked inherited neuromuscular disorder caused by pathogenic variants in the dystrophin gene (DMD; locus Xp21.2). The variant spectrum of DMD is unique in that 65% of causative mutations are intragenic deletions, with intragenic duplications and point mutations (along with other sequence variants) accounting for 6% to 10% and 30% to 35%, respectively. The traditional strategy for molecular diagnostic testing for DMD involves initial screening for deletions/duplications using microarray‐based comparative genomic hybridization followed by a full‐sequence analysis of DMD for sequence variants. This traditional strategy is expensive and time‐consuming due to the involvement of two separate tests to detect all types of variants in the DMD gene. Recent advancements in next‐generation sequencing (NGS) technology and improvements in analysis algorithms related to copy number variant detection ultimately resulted in the development of a single NGS‐based assay to detect all variant types, including deletions/duplications and sequence variants. This article initially discusses the strategic algorithm for establishing a molecular diagnosis of DMD and later provides detailed molecular diagnostic protocols for DMD, including an NGS‐based sequencing assay with sequence and copy number variant analysis. © 2023 Wiley Periodicals LLC.Basic Protocol: Next‐generation sequencing of the entire genomic sequence of the DMD gene using IDT xGen Lockdown Probes
Optimization of a capacitive wireless power transfer system with two electric field repeaters
Authors: Minnaert Ben , Monti Giuseppina 
Published: February 2023

SummaryIn this paper, a capacitive wireless power transfer link with two repeaters between the transmitter and receiver is analyzed. The performance of the system is optimized by maximizing the different gains. Two approaches of practical interest are analytically studied and solved. First, the couplings between different resonators is considered fixed and the optimal load and source of the system are determined as function of the network characteristics. Second, the performance is optimized by varying the couplings between resonators for a configuration with a given (nonideal) source and load. The analytical results are verified through circuital simulations. It is demonstrated that, under certain conditions, both approaches allow for the maximization of the different gains, resulting in more optimization options than a single repeater configuration.

Published: February 2023

AbstractAutism spectrum disorder (ASD) is a neurodevelopmental disorder linked to several genetic and environmental factors including antenatal stress. Hence, we aimed to examine whether a mother's stress during pregnancy is associated with the severity of autism spectrum disorder in children. The study was conducted with 459 mothers of children with autism (aged 2–14 years) who were attending rehabilitation and educational centers in the two major cities of Makkah and Jeddah in Saudi Arabia. Environmental factors, consanguinity, and ASD family history were assessed using a validated questionnaire. The Prenatal Life Events Scale questionnaire was used to assess whether the mothers were exposed to stress during pregnancy. Two models of ordinal regression analysis were conducted including gender, child age maternal age, parental age, maternal education, parental education, income nicotine exposure, mother taking medication during pregnancy, family history of ASD, gestation, consanguinity, exposure of prenatal life events (in model 1), and severity of prenatal life events (in model 2). Family history of ASD showed a statistically significant association with the severity of ASD in both regression models (p = .015, odds ratio [OR]: 4.261 in Model 1, and p = .014, OR: 4.901 in model 2). In model 2, the moderate severity prenatal life events showed higher statistically significant adjusted odds ratio for ASD severity compared to no stress (p = .031; OR: 3.82). Within the limitations of this study, prenatal stressors showed some potential contribution to ASD severity. Family history of ASD was the only factor that showed a persistent association with ASD severity. A study that assesses the effect of COVID‐19 stress on ASD prevalence and severity is recommended.

Published: February 2023

SummaryTransposon systems are widely used for genetic engineering in various model organisms. PiggyBac (PB) has recently been confirmed to have highly efficient transposition in the mouse germ line and mammalian cell lines. In this study, we used a modified PB transposon system mediated by PB transposase (PBase) mRNA carrying the human lactoferrin gene driven by bovine β‐casein promoter to transfect bovine mammary epithelial cells (BMECs), and the selectable reporter in two stable transgenic BMEC clones was removed using cell‐permeant Cre recombinase. These reporter‐free transgenic BMECs were used as donor cells for somatic cell nuclear transfer (SCNT) and exhibited a competence of SCNT embryos similar to stable transgenic BMECs and nontransgenic BMECs. The comprehensive information from this study provided a modified approach using an altered PB transposon system mediated by PBase mRNA in vitro and combined with the Cre/loxP system to produce transgenic and selectable reporter‐free donor nuclei for SCNT. Consequently, the production of safe bovine mammary bioreactors can be promoted.

AbstractCanada's livestock production and human populations are concentrated in southern regions. Understanding spatial and temporal distributions of animals and excreted nutrients is key to optimizing manure resources and minimizing impact of livestock. Here, we identify manureshed concerns and opportunities by reconciling nitrogen supply and demand on a regional and national scale. Data based on national statistics and farm surveys were allocated to homogeneous soil polygons (Soil Landscapes of Canada [SLC]) to quantify changes in nutrient distribution and ammonia (NH3) emissions across Canada (1981–2018). Livestock sectors tied to domestic consumption, dairy and poultry, were stable over time and well dispersed. Export driven beef production has moved west since 1981, whereas pig production was prominent in Manitoba, Quebec, and Ontario. Per ha manure N excretion across livestock sectors in 2018 was generally low with 58% and 6% of the SLCs averaging <25 and >100 kg N ha−1, respectively. Although only 3% of SLCs had average NH3 emissions reaching 16–200 kg ha−1, most of these were located near cities and emissions spiked in spring when more people might be exposed. The greatest concentrations of nutrients and livestock occurred around the three largest metropolitan areas: Toronto, Montreal–Quebec City, and Vancouver, posing challenges for nutrient recycling and public health. This study shows that as Canadian cities and livestock agriculture grow in southern Canada, so will challenges around food production, human health, and managing nutrients. Livestock and land use strategies are needed to reconcile changing animal sectors and growing populations.

BackgroundAbdominal aortic aneurysms (AAAs) may rupture before reaching maximum diameter (Dmax) thresholds for repair. Aortic wall microvasculature has been associated with elastin content and rupture sites in specimens, but its relation to progression is unknown.PurposeTo investigate whether dynamic contrast‐enhanced (DCE) MRI of AAA is associated with Dmax or growth.Study TypeProspective.PopulationA total of 27 male patients with infrarenal AAA (mean age ± standard deviation = 75 ± 5 years) under surveillance with DCE MRI and 2 years of prior follow‐up intervals with computed tomography (CT) or MRI.Field Strength/SequenceA 3‐T, dynamic three‐dimensional (3D) fast gradient‐echo stack‐of‐stars volumetric interpolated breath‐hold examination (Star‐VIBE).AssessmentWall voxels were manually segmented in two consecutive slices at the level of Dmax. We measured slope to 1‐minute and area under the curve (AUC) to 1 minute and 4 minutes of the signal intensity change postcontrast relative to that precontrast arrival, and, Ktrans, a measure of microvascular permeability, using the Patlak model. These were averaged over all wall voxels for association to Dmax and growth rate, and, over left/right and anterior/posterior quadrants for testing circumferential homogeneity. Dmax was measured orthogonal to the aortic centerline and growth rate was calculated by linear fit of Dmax measurements.Statistical TestsPearson correlation and linear mixed effects models. A P value <0.05 was considered statistically significant.ResultsIn 44 DCE MRIs, mean Dmax was 45 ± 7 mm and growth rate in 1.5 ± 0.4 years of prior follow‐up was 1.7 ± 1.2 mm per year. DCE measurements correlated with each other (Pearson r = 0.39–0.99) and significantly differed between anterior/posterior versus left/right quadrants. DCE measurements were not significantly associated with Dmax (P = 0.084, 0.289, 0.054 and 0.255 for slope, AUC at 1 minute and 4 minutes, and Ktrans, respectively). Slope and 4 minutes AUC significantly associated with growth rate after controlling for Dmax.ConclusionContrast uptake may be increased in lateral aspects of the AAA. Contrast enhancement 1‐minute slope and 4‐minutes AUC may be associated with a period of recent AAA growth that is independent of Dmax.Evidence Level3.Technical EfficacyStage 2.

AbstractBackgroundFertilization with organic waste compost can close the nutrient cycles between urban and rural environments. However, its effect on yield and soil fertility must be investigated.AimThis study investigated the long‐term effect of compost on soil nutrient and potentially toxic elements (PTEs) concentration, nutrient budgets, and nitrogen (N) mineralization and efficiency.MethodsAfter 21 years of annual compost application (100/400 kg N ha–1 year–1 [100BC/400BC]) alone and combined with mineral fertilization, soil was analyzed for pH, organic carbon (SOC), nutrient (total N and P, Nmin, extractable CAL‐P, CAL‐K, and Mg), and PTE (Cu, Ni, Zn) concentrations. Yields were recorded and nutrient/PTE budgets and apparent net mineralization (ANM, only 2019) were calculated.ResultsN efficiency was the highest in maize and for mineral fertilization. Compost application led to lower N efficiencies, but increased ANM, SOC, pH, and soil N, and surpluses of N, P, and all PTEs. Higher PTE concentrations were only found in 400BC for Cu. Nutrient budgets correlated with soil nutrient concentration. A surplus of 16.1 kg P ha–1 year–1 and 19.5 kg K ha–1 year–1 resulted in 1 mg kg–1 increase in CAL‐P and CAL‐K over 21 years.ConclusionCompost application supplies nutrients to crops with a minor risk of soil‐accumulation of PTEs. However, the nutrient stoichiometry provided by compost does not match crop offtakes causing imbalances. Synchronization of compost N mineralization and plant N demand does not match and limits the yield effect. In winter wheat only 65–70% of N mineralization occurred during the growth period.

Published: February 2023

AbstractBackgroundNuoshanyao (NSY) is a special species of Chinese yam (Dioscorea opposita Thunb.) and shows rich functionality and superior nutritional value. The chemical components and structural properties of Nuoshanyao polysaccharide (NSYP) were investigated in his study.ResultsThe molecular weight (Mw) of the major component in the polysaccharide was 23 kDa. NSYP was mainly composed of glucose, mannose, and galactose, and the molar ratio was 36.5:1.63:1. There might be an ordered helical conformation in NSYP, and the surface of NSYP was granular. NSYP exhibited strong scavenging capacity on the DPPH radical and chelating capacity on the ferrous ion in vitro with a rate of 94.94% and 82.49% at 4 mg/mL.ConclusionNSYP with the appropriate molecular weight range and helix structure could possess great antioxidant activity, while monosaccharide compositions may affect the activity. This work supplied important information for the potential application of NSYP in the nutritional and food industries.
