AbstractClean energy production and saving play vital impacts on the sustainability of the global community. Herein, high‐performance semitransparent organic solar cells (ST‐OSCs) with excellent features of power generation, being see‐through, and infrared reflection of heat dissipation, with promising perspectives for building‐integrated photovoltaics (BIPVs) are reported. To simultaneously improve average visible transmittance (AVT) and power conversion efficiency (PCE), formally in a trade‐off relationship, of ST‐OSCs, new ternary blends with alloy‐like near‐infrared (NIR) acceptors are employed, which are effective to improve device efficiency while maintaining visible absorption unchanged, resulting in PCEs of 16.8% for opaque devices and 13.1% for semitransparent OSCs (AVT of 22.4% and infrared photon radiation rejection (IRR) of 77%). Further, multifunctional ST‐OSCs are realized via introducing simple, yet effective photonic reflectors, together with optical simulation, leading to not only perfect fitting of the visible transmittance peak (555 nm) to the photopic response of the human eye but also an excellent IRR of 90% (780–2500 nm), along with 23% AVT and over 12% PCE. This is thought to be the best‐performing multifunctional ST‐OSC with promising prospects as BIPVs in terms of power generation, heat dissipation, and being see‐through.

AbstractOne of the key challenges of perovskite photovoltaics is the scalable fabrication of high‐efficiency perovskite solar cells (PSCs). Not only the scalable deposition of high‐quality perovskite thin‐films itself, but also the adjacent charge extraction layers is pivotal. In this work, PSCs based on all‐inkjet‐printed absorber and extraction layers are presented, allowing for a scalable and material‐efficient deposition. The inkjet‐printed PSCs are of p–i–n‐architecture with a precursor‐based nickel oxide hole‐transport layer, a high‐quality inkjet‐printed triple‐cation (methylammonium, formamidinium, and cesium) perovskite absorber layer and a double layer electron‐transport layer of phenyl‐C61‐butyric acid methyl ester and bathocuproine. The ink properties, inkjet parameters, and annealing procedure are optimized for each layer. PSCs with such inkjet‐printed absorber and charge carrier extraction layers demonstrate an efficiency of >17% with low hysteresis. Although printed in ambient atmosphere, the devices show excellent short‐term stability (40 h) even under elevated temperature (85 °C). These results are a promising next step on the way to fully inkjet‐printed perovskite solar cells, including both electrodes as well.

Published: July 2020

BackgroundAllergic rhinitis (AR) symptoms exhibit prominent 24‐hour variations associated with the biological clock. Although endogenous glucocorticoids synchronize circadian oscillator in the nasal mucosa, the precise mechanism of AR remains unclear. Therefore, using a mouse model, we investigated the association between circadian‐clock genes and AR symptoms at various time‐points.MethodsBased on the rhythmic secretion of corticosterone levels, we chose 2 time‐points, ZT4 (10:00 AM) and ZT16 (10:00 PM), to observe dynamic changes of nasal symptoms, immunologic responses, and circadian‐clock gene period (Per) expressions.ResultsIn the AR group, nasal symptom scores at ZT4 were significantly higher than at ZT16, with a greater increase in eosinophils, mast cells, and total immunoglobulin E levels at ZT4. The scores had a negative correlation with fluctuation of corticosterone levels. T‐helper 1 (Th1) cell counts and interferon‐γ levels decreased significantly at ZT4 compared with ZT16 in the AR group, whereas Th2 cells; Th17 cells; and interleukin (IL)‐4, ‐13, and ‐17A levels increased significantly at ZT4 compared with ZT16. Furthermore, Per2 gene expression levels were attenuated at ZT4 and elevated at ZT16, but correlated negatively with Th2 and Th17 responses associated with Gata3 and Rorγt expression levels that were enhanced at ZT4 and reduced at ZT16 in the AR group.ConclusionOur results suggest that the Per2 gene may influence diurnal variations of AR symptom severity, partially through its possible anti‐inflammatory effect on the circadian regulation of GATA3 and RORγt levels in immune cells. This further demonstrates the neural‐immune‐endocrinal mechanism of circadian rhythm in AR and sheds new light on chronotherapeutic approaches to AR.

AbstractIntriguing properties and functions are expected to implant into metal–organic layers (MOLs) to achieve tailored pore environments and multiple functionalities owing to the synergies among multiple components. Herein, we demonstrate a facile one‐pot synthetic strategy to incorporate multiple functionalities into stable zirconium MOLs via secondary ligand pillaring. Through the combination of Zr6‐BTB (BTB=benzene‐1,3,5‐tribenzoate) layers and diverse secondary ligands (including ditopic and tetratopic linkers), 31 MOFs with multi‐functionalities were systematically prepared. Notably, a metal–phthalocyanine fragment was successfully incorporated into this Zr‐MOL system, giving rise to an ideal platform for the selective oxidation of anthracene. The organic functionalization of two‐dimensional MOLs can generate tunable porous structures and environments, which may facilitate the excellent catalytic performance of as‐synthesized materials.
A Phosphanyl‐Phosphagallene that Functions as a Frustrated Lewis Pair

Published: July 2020

AbstractPhosphagallenes (1 a/1 b) featuring double bonds between phosphorus and gallium were synthesized by reaction of (phosphanyl)phosphaketenes with the gallium carbenoid Ga(Nacnac) (Nacnac=HC[C(Me)N(2,6‐i‐Pr2C6H3)]2). The stability of these species is dependent on the saturation of the phosphanyl moiety. 1 a, which bears an unsaturated phosphanyl ring, rearranges in solution to yield a spirocyclic compound (2) which contains a P=P bond. The saturated variant 1 b is stable even at elevated temperatures. 1 b behaves as a frustrated Lewis pair capable of activation of H2 and forms a 1:1 adduct with CO2.

Published: July 2020

AbstractAlkaline phosphatase (ALP) is an important biomarker, as high levels of ALP in blood can indicate liver disease or bone disorders. However, current clinical blood tests only measure the total concentration of ALP but are unable to distinguish enzyme isotypes. Here, we demonstrate a novel and rapid approach to profile various ALP isozymes in blood via a single‐molecule‐analysis platform. The microarray platform provides enzyme kinetics of hundreds of individual molecules at high throughput. Using these single molecule kinetics, we characterize the different activity profiles of ALP isotypes. By analyzing both healthy and disease samples, we found the single molecule activity distribution of ALP in serum reflects the health status of patients. This result demonstrates the potential utility of the method for improving the conventional ALP test, as well as for analyzing other enzymatic biomarkers, including enzyme isotypes.

Published: July 2020

AbstractThe main purpose of this study was the identification of unconscious maternal phantasies in lullabies used by contemporary mothers and the exploration of differences and similarities with the phantasies unveiled in traditional bedtime songs, collected in ethnographic research, and used in a previous reference study. Participants included a total of 84 women aged between 22 and 47 years (M = 34.22; SD = 4.74) with children of both sexes aged 2–36 months (M = 19.01; SD = 10.79). A total of 70 songs were collected, which were the subject of content analysis and categorization by three independent judges. Data show that 54.8% of the mothers still use lullabies when they put their children to sleep, and that intergenerational transmission of songs is present through maternal lineage. As expected, regularities and differences were identified between the contents of contemporary and traditional lullabies, but regardless of variances in time and culture, both of them seem imbued by the mother's symbolic work through on the imaginary dimension of the child's (and her own's) internal object phantasies.

AbstractMetal–organic frameworks (MOFs) or covalent–organic frameworks (COFs) have gained increasing attentions due to their high surface area, tunable structure, highly ordered pores and functional composition. Besides their applications in gas adsorption and separation, hydrogen storage, optics, magnetism and drug delivery, they have been widely employed as cathodes, anodes and separators for the research and development in lithium‐ion batteries (LIBs) due to the tunable structure, multi‐electron transfer, short pathway, and robust structural stability, etc. This review summarizes the general applied strategies and cases of MOF, COF and their composites as well as derivatives in LIBs. Compared to inorganic materials, the advantages of MOF/COF materials have made it possible to witness various successful cases with enhanced electrochemical performances. Moreover, this review provides some guidance for the controllable preparation and modification of MOF‐ and COF‐derived nanostructures through molecular engineering, rational design, and doping, as well as functional group modifications. In addition, we highlight timely progresses of the application of organic frameworks in LIBs, and also summarize many strategies of MOF/COF materials and their derivatives on enhancing the energy density, diffusion coefficient, rate performance and cycling stability for next‐generation LIBs with attractive features of high energy density, good rate performance, and superior cyclability.
Neuronal Compartmentalization: A Means to Integrate Sensory Input at the Earliest Stage of Information Processing?

Published: July 2020

AbstractIn numerous peripheral sense organs, external stimuli are detected by primary sensory neurons compartmentalized within specialized structures composed of cuticular or epithelial tissue. Beyond reflecting developmental constraints, such compartmentalization also provides opportunities for grouped neurons to functionally interact. Here, the authors review and illustrate the prevalence of these structural units, describe characteristics of compartmentalized neurons, and consider possible interactions between these cells. This article discusses instances of neuronal crosstalk, examples of which are observed in the vertebrate tastebuds and multiple types of arthropod chemosensory hairs. Particular attention is paid to insect olfaction, which presents especially well‐characterized mechanisms of functional, cross‐neuronal interactions. These examples highlight the potential impact of peripheral processing, which likely contributes more to signal integration than previously considered. In surveying a wide variety of structural units, it is hoped that this article will stimulate future research that determines whether grouped neurons in other sensory systems can also communicate to impact information processing.

Published: July 2020

AbstractIntroductionGraph metrics have been proposed as potential biomarkers for diagnosis in clinical work. However, before it can be applied in a clinical setting, their reproducibility should be evaluated.MethodsThis study systematically investigated the effect of two denoising pipelines and different whole‐brain network constructions on reproducibility of subject‐specific graph measures. We used the multi‐session fMRI dataset from the Brain Genomics Superstruct Project consisting of 69 healthy young adults.ResultsIn binary networks, the test–retest variability for global measures was large at low density irrespective of the denoising strategy or the type of correlation. Weighted networks showed very low test–retest values (and thus a good reproducibility) for global graph measures irrespective of the strategy used. Comparing the test–retest values for different strategies, there were significant main effects of the type of correlation (Pearson correlation vs. partial correlation), the (partial) correlation value (absolute vs. positive vs. negative), and weight calculation (based on the raw (partial) correlation values vs. based on transformed Z‐values). There was also a significant interaction effect between type of correlation and weight calculation. Similarly as for the binary networks, there was no main effect of the denoising pipeline.ConclusionOur results demonstrated that normalized global graph measures based on a weighted network using the absolute (partial) correlation as weight were reproducible. The denoising pipeline and the granularity of the whole‐brain parcellation used to define the nodes were not critical for the reproducibility of normalized graph measures.

AbstractOver the past decades, organometallic complexes with precious elements, such as ruthenium and iridium, are widely used as visible‐light photoredox catalysts. Recently, more and more complexes based on earth‐abundant and inexpensive elements have been used as sensitizers in photochemistry. Although the photoexcited state lifetimes of iron complexes are typically shorter than those of traditional photosensitizers, the utilization of iron catalysts in photochemistry has sprung up owing to their abundance, low price, nontoxicity, and novel properties, including exhibiting ligand to metal charge transfer states. This concept focuses on recent advances in light‐driven iron catalysis in organic transformations, including iron/photoredox dual catalysis, light‐induced iron photoredox catalysis and light‐induced generation of active iron catalysts. The prospect for the future of this field is also discussed.

AbstractEnantioselective hydrogenation of a broad spectrum of N‐, O‐, and S‐containing aromatic benzoheterocycles or nonaromatic unsaturated heterocycles has been realized by using an Ir/SpinPHOX (SpinPHOX=spiro[4,4]‐1,6‐nonadiene‐based phosphine‐oxazoline) complex as the catalyst, affording an array of the corresponding chiral benzoheterocycles (30 examples) with excellent enantioselectivities (>99 % ee in most cases) and turnover numbers up to 500.

BackgroundPhysical activity (PA) is recommended for women with breast cancer (BC); however, data are sparse on the association of PA with quality of life (QOL) and patient‐reported symptoms for women on adjuvant endocrine therapy (AET).MethodsWomen with hormone receptor–positive BC who were taking AET completed standardized surveys about their health‐related QOL, AET‐related symptoms, and levels of PA using validated measures. A Wald chi‐square test and an analysis of variance were used to assess associations with PA and independent variables. Generalized linear regression analyses assessed associations between PA, QOL, and AET‐related symptoms.ResultsThe analytic cohort included 485 Black and White women. Black race, a high body mass index (BMI), and being on aromatase inhibitors (vs tamoxifen) were associated with lower PA in a bivariate analysis. In a multivariate analysis, lower self‐reported PA was associated with a high BMI (P = .02) and chemotherapy uptake (P = .006). Better health‐related QOL (P = .01), less severe overall AET‐related symptoms (P = .02), and less severe gynecological symptoms (P = .03) were associated with increasing levels of moderate PA.ConclusionsAmong women taking AET, moderate levels of PA may be associated with fewer medication‐related symptoms and overall better ratings of health‐related QOL. Because of the low levels of PA observed in the sample overall and particularly for Black women, identifying successful strategies to promote PA are needed.
Bulk‐immiscible AgRh Alloy Nanoparticles as a Highly Active Electrocatalyst for the Hydrogen Evolution Reaction
Authors: Darling Albert J. , Stewart Shea , Holder Cameron F. , Schaak Raymond E. 
Published: July 2020

AbstractAlloying metals can achieve enhanced kinetics for the hydrogen evolution reaction (HER), but most known HER alloy catalysts combine metals that are miscible in the bulk. Theoretical studies suggest that bulk‐immiscible AgRh alloys will exhibit near‐zero hydrogen binding energies, which is important for high‐performing HER catalysts. Current routes to AgRh nanoparticles yield only small quantities or require specialized setups. Here, we establish a ligand‐free, scalable synthesis of AgRh nanoparticles and demonstrate their catalytic viability for the HER under acidic conditions. AgRh nanoparticle electrodes exhibited low operating potentials with current densities of −10 and −100 mA/cm2 at overpotentials of −17 and −32 mV, respectively. The electrodes were highly durable with very little change in overpotentials required to maintain hydrogen production for 24 h and after 400 successive cycles. These results establish bulk‐immiscible AgRh alloys as promising non‐Pt HER catalysts.

AbstractObjectivesLoss of vaccine‐induced antibodies (Abs) after chemotherapy against paediatric acute lymphoblastic leukaemia (ALL) is common and often necessitates re‐immunisation after cessation of treatment. Even so, some ALL survivors fail to mount or to maintain protective Abs. Germinal centres (GCs) are clusters of proliferating B cells in follicles of secondary lymphoid tissues (SLTs) formed during adaptive immune responses and the origins of long‐lived memory B and plasma cells that are the source of Abs. Furthermore, productive GC reactions depend on T follicular helper (TFH) cells. To understand why chemotherapy induces deficits in Ab responses, we examined how SLTs were affected by chemotherapy.MethodsRhesus macaques were infused with either three cycles of the anthracycline doxorubicin or saline, followed by immunisation with a de novo and booster antigen. Spleen and lymph nodes were removed, and memory B, bulk T and TFH cells were examined.ResultsDespite adequate GC morphology, a diminished memory and IgG+ B‐cell population along with diminished total and booster vaccine‐specific IgG‐producing memory B cells were noted in the spleens of macaques with past doxorubicin exposure compared to the saline‐treated controls (P < 0.05). Intact bulk T and TFH cells were found in the SLTs of treated macaques, which displayed higher CD40L upregulation capacity by their splenic CXCR5+ helper T cells (P < 0.01). In contrast to the spleen, the immune cell populations studied were comparable between the lymph nodes of both saline‐ and doxorubicin‐treated macaques.ConclusionOur findings suggest that the splenic memory B‐cell subset, compared to its lymph node counterpart, is more severely altered by anthracycline treatment.

AbstractThis paper investigates species richness and species occupancy frequency distributions (SOFD) as well as patterns of abundance–occupancy relationship (SAOR) in Odonata (dragonflies and damselflies) in a subtropical area. A total of 82 species and 1983 individuals were noted from 73 permanent and temporal water bodies (lakes and ponds) in the Pampa biome in southern Brazil. Odonate species occupancy ranged from 1 to 54. There were few widely distributed generalist species and several specialist species with a restricted distribution. About 70% of the species occurred in <10% of the water bodies, yielding a surprisingly high number of rare species, often making up the majority of the communities. No difference in species richness was found between temporal and permanent water bodies. Both temporal and permanent water bodies had odonate assemblages that fitted best with the unimodal satellite SOFD pattern. It seems that unimodal satellite SOFD pattern frequently occurred in the aquatic habitats. The SAOR pattern was positive and did not differ between permanent and temporal water bodies. Our results are consistent with a niche‐based model rather than a metapopulation dynamic model.
