Recently, researchers have been interested in how autistic people experience loneliness. Yet, most of this research has focused on loneliness in autistic children and young people. We present the results of a systematic review on loneliness in autistic adults. A systematic review is a rigorous way of searching for all existing research on a topic and summarizing the findings about specific questions. We searched for all research published on this topic until 9 April 2021. We found 34 articles that investigated loneliness in autistic adults. This research showed that (1) there is fairly little research that has involved directly asking autistic adults about their first-hand experiences of loneliness (e.g. what loneliness feels like for them); (2) few research studies have used loneliness questionnaires specifically developed for autistic adults (this was attempted in just one research study); (3) collective loneliness (i.e. loneliness associated with how much an autistic person feels they 'fit in' to societyce, for example. In our article, we discuss the kinds of future research on loneliness in autistic adults that might be useful.
Autism spectrum disorder is an early onset neurodevelopmental disorder and diagnosis can be made as early as 18 months of age. Early diagnosis of autism spectrum disorder is critical as it leads to early intervention. Age of autism spectrum disorder diagnosis has been linked to the child profile as autism spectrum disorder is characterized by strong heterogeneity, but is also influenced by socio-economic factors. There is paucity of data on age of diagnosis of autism spectrum disorder in France. We therefore examined the age of autism spectrum disorder diagnosis in 554 children and adolescents enrolled in the ELENA cohort study with respect to the influences of child profile, family antecedents, and socio-economic factors. The mean age of diagnosis was 4.9 years (±2.8 years). Early diagnosis, before 3 years of age, was related to the co-occurrence of intellectual disability, higher autism spectrum disorder symptom severity, and lower communicative abilities. Children in low socio-economic status families teis was not associated with the presence of an older sibling with autism spectrum disorder. The observed current trend of an inverse relationship between socio-economic status and age of diagnosis of autism spectrum disorder suggests equitable access to autism spectrum disorder services in France where health coverage is universal and free. Better screening of more subtle/less severe forms of autism spectrum disorder is needed, as well as further assessment of the link between the co-occurrence of autism spectrum disorder and intellectual impairment in children in lower socio-economic status families.A series of fully fused n-type mixed conduction lactam polymers p(g7NCnN), systematically increasing the alkyl side chain content, are synthesized via an inexpensive, nontoxic, precious-metal-free aldol polycondensation. Employing these polymers as channel materials in organic electrochemical transistors (OECTs) affords state-of-the-art n-type performance with p(g7NC10N) recording an OECT electron mobility of 1.20 × 10-2 cm2 V-1 s-1 and a μC* figure of merit of 1.83 F cm-1 V-1 s-1. In parallel to high OECT performance, upon solution doping with (4-(1,3-dimethyl-2,3-dihydro-1H-benzoimidazol-2-yl)phenyl)dimethylamine (N-DMBI), the highest thermoelectric performance is observed for p(g7NC4N), with a maximum electrical conductivity of 7.67 S cm-1 and a power factor of 10.4 μW m-1 K-2. These results are among the highest reported for n-type polymers. Importantly, while this series of fused polylactam organic mixed ionic-electronic conductors (OMIECs) highlights that synthetic molecular design strategies to bolster OECT performance can be translated to also achieve high organic thermoelectric (OTE) performance, a nuanced synthetic approach must be used to optimize performance. Herein, we outline the performance metrics and provide new insights into the molecular design guidelines for the next generation of high-performance n-type materials for mixed conduction applications, presenting for the first time the results of a single polymer series within both OECT and OTE applications.Herein, by replacement of the linear terephthalate linker with the bending 2,5-thiophenedicarboxylate (tdc2-) linker in the typical (3,9)-connected metal-organic framework, with a reduced 8-connected hydroxyl-centered trinuclear cluster, a new (3,8)-connected network, [Ni3(μ3-OH)(tdc)3(tpp)] [DZU-1; tpp = 2,4,6-tris(4-pyridyl)pyridine], was synthesized. The modified pore environment enables DZU-1 to selectively adsorb C2H2 over CO2 in an efficient manner.The optoelectronic properties of lead halide perovskite thin films can be tuned through compositional variations and strain, but the associated nanocrystalline structure makes it difficult to untangle the link between composition, processing conditions, and ultimately material properties and degradation. Here, we study the effect of processing conditions and degradation on the local photoconductivity dynamics in [(CsPbI3)0.05(FAPbI3)0.85(MAPbBr3)0.15] and (FA0.7Cs0.3PbI3) perovskite thin films using temporally and spectrally resolved microwave near-field microscopy with a temporal resolution as high as 5 ns and a spatial resolution better than 50 nm. For the latter FACs formulation, we find a clear effect of the process annealing temperature on film morphology, stability, and spatial photoconductivity distribution. After exposure of samples to ambient conditions and illumination, we find spectral evidence of halide segregation-induced degradation below the instrument resolution limit for the mixed halide formulation, while we find a clear spatially inhomogeneous increase in the carrier lifetime for the FACs formulation annealed at 180 °C.The importance of alloy-shelling in optically robust Core/Alloy-Shell (CAS) QDs has been described from structural and energetic aspects. Unlike fluorescent dyes, both Core/Shell (CS) and CAS QDs exhibit excitation-energy-dependent photoluminescence quantum yield (PLQY). For both CdSe and InP CAS QDs (with metal- and nonmetal-based alloy-shelling, respectively), with increasing excitation energy, (a) the ultrafast rise-time or relaxation-time to the band-edge increases and (b) the magnitude of the normalized bleach signal decreases. Ultrasensitive single-particle spectroscopic investigation results showed that with decreasing excitation energy, (a) the fraction of ON events increases, (b) the ratio of exciton-detrapping rate/trapping rate increases, and (c) the extent of beneficial hole trapping increases. A relative decrease in PLQY with increasing excitation energy is much less pronounced in CAS QDs than in CS QDs. Unless trap states are removed completely especially in the higher-energy landscape, PLQY will remain inherently dependent on excitation energy for QDs in the vast energy landscape. When reporting the PLQY of QDs, the magnitude of the excitation energy must be mentioned.The growing world population creates an ever-increasing demand for fresh drinkable water, and many researchers have discovered the emerging capacitive deionization (CDI) technique to be highly promising for desalination. Traditional modeling of CDI has focused on charge storage in electrical double layers, but recent studies have presented a dynamic Langmuir (DL) approach as a simple and stable alternative. We here demonstrate, for the first time, that a Langmuir-based approach can simulate CDI in multiple dimensions. This provides a new perspective of different physical pictures that could be used to describe the detailed CDI processes. As CDI emerges, effective modeling of large-scale and pilot CDI modules is becoming increasingly important, but such a modeling could also be especially complex. Leveraging the stability of the DL model, we propose an alternative fundamental approach based on relaxed adsorption-flow computations that can dissolve these complexity barriers. Literature data extensively validate the findings, which show how the Langmuir-based approach can simulate and predict how key changes in operational and structural conditions affect the CDI performance. Crucially, the method is tractable for simple simulations of large-scale and structurally complex systems. Put together, this work presents new avenues for approaching the challenges in modeling CDI.Fibrous surfaces in nature have already exhibited excellent functions that are normally ascribed to the synergistic effects of special structures and material properties. The honey bee tongue, foraging liquid food in nature, has a unique segmented surface covered with dense hairs. Since honey bees are capable of using their tongue to adapt to possibly the broadest range of feeding environments to exploit every possible source of liquids, the surface properties of the tongue, especially the covering hairs, would likely represent an evolutionary optimization. In this paper, we show that their tongue hairs are stiff and hydrophobic, the latter of which is highly unexpected as the structure is designed for liquid capturing. We found that such hydrophobicity can prevent those stiff hairs from being adhered to the soft tongue surface, which could significantly enhance the deformability of the tongue when honey bees feed at various surfaces and promote their adaptability to different environments. These findings bridge the relationship between surface wettability and structural characteristics, which may shed new light on designing flexible microstructured fiber systems to transport viscous liquids.Mechanical forces have profound effects on the morphology and migration of cells in a two-dimensional environment. However, cells in vivo mostly migrate in three-dimensional space while physically constrained, and the mechanism by which cellular dynamic forces drive migration in this confined environment is unclear. Lysipressin Here, we present a method of fabricating microfluidic chips with integrated DNA-based tension probes to measure spatiotemporal variations in integrin-mediated force exerted during confined cell migration. Using this developed device, we measured the spatial locations, magnitudes, and temporal characteristics of integrin-ligand tension signals in motile cells in different microchannels and found that cells exerted less force and underwent increasingly transitory integrin-ligand interactions when migrating in confined spaces. This study demonstrates that the described method provides insights into understanding the migratory machinery of cells in geometrically confined environment that better mimics physiological conditions.Functionalized biocarriers that can perform bio-orthogonal reactions in tumor cells may provide solutions to overcome the efflux of the chemotherapeutic agent from drug-resistant tumor cells. Herein, we report the enrichment of therapeutic drugs in tumor cells through intracellular click reaction with functionalized bacteria. Specifically, an intracellular bioactive drug enrichment template (OPV@Escherichia coli) is constructed by combining positively charged oligo(phenylene-vinylene)-alkyne (OPV-C≡CH) with E. coli via electrostatic interaction. After the cell uptake of OPV@E. coli and Cu(II)-based complex, Cu(I) generated in situ can catalyze the bio-orthogonal click reaction to covalently anchor the azide-bearing molecules of cyanine 5 (Cy5-N3) and paclitaxel (PTX-N3) on OPV@E. coli. These molecules and their functions were retained and enriched inside the drug-resistant tumor cells A549T, which can label cells with fluorescent probes and selectively induce the apoptosis of drug-resistant tumor cells.
