Since OLED was first mass‐produced by Samsung Display, various researches related to OLEDs have been actively conducted and now days, People are using OLED displays every single day. As a next generation organic‐optoelectronic display, we suggest the All‐in‐one Sensor Display which can be used for fingerprint recognition, proximity sensor, illuminance sensing and photoplethysmogram which is an area of rapid interest in recent years. To demonstrate the All‐in‐one Sensor Display in entire display area, in this research, we successfully fabricated organic photodetectors (OPDs) in the OLED panels with our own materials, D‐01 and A‐01. Since designing a donor material and an acceptor material is key issue for high Signal to Noise ratio (SNR), we designed and synthesized the D‐01 and A‐01. With our own material based OPDs, All‐in‐one Sensor Display showed good characteristics and successfully recognized fingerprints. This research shows the possibility of the mass production of next organic diode and we believe that All‐in‐one Sensor Display will be the next display application beyond the OLEDs.

To realize the full performance of Zn–air batteries, the co‐presence of a highly efficient oxygen reduction reaction (ORR) and an oxygen evolution reaction (OER) in the system is critical. Although copper and nickel are known to be bifunctional catalysts for ORR and OER, sluggish reactions as a result of the exceptionally strong O=O bond on the metal surface make it difficult to achieve high system efficiency. In this study, a metal carbide layer (CuCx and NiCx) on dendritic copper and nickel is fabricated by a facile electrodeposition process to provide efficient catalytic active sites with moderate binding energy for easy electron transfer in both the OER and the ORR. The dendritic structure provides an enriched catalytic surface and the protective metal carbide layer offers an appropriate O binding energy and durability of Zn–air batteries. Owing to the presence of the stable metal carbide surface on the dendritic metal, the CuCx/Cu and NiCx/Ni catalysts exhibited well‐defined limiting current densities of −5.19 and −5.11 mA cm−2, respectively, and improved ORR and OER activities with lower polarization than the corresponding metal catalysts. Density functional theory revealed a 0.74 eV decrease in the overpotential of NiCx/Ni‐catalyzed OER reactions compared with Ni‐catalyzed OER reactions. The experimental and theoretical results prove that carbide layers on dendritic metal surfaces can greatly improve the activity of ORR and OER bifunctional electrocatalysts for Zn–air batteries. Carbide loading: NiCx/Ni is reported as a promising bifunctional electrocatalyst for alkaline‐based rechargeable Zn–air batteries. The metal carbide catalyst provides better durability against methanol than Pt/C for direct methanol fuel cells and Zn–air batteries. DFT analysis reveals that NiCx/Ni requires less overpotential to complete the reaction and shifts the binding energy of oxygen into a suitable region for efficient catalytic activities.

Introduction: Tracheal intubation using video laryngoscopes has been a better approach for trauma patients requiring cervical immobilisation. The aim of this study was to compare the time to successful intubation by novice intubators using three types of intubation stylets with the new McGrath MAC video laryngoscope in a manikin model. Methods: This was a randomised crossover manikin study. The participants performed tracheal intubations using three intubation stylets (arcuate shape malleable stylet, McGrath MAC-shaped malleable stylet and McGrath MAC-shaped rigid stylet) in a difficult airway model with cervical immobilisation. The order of the stylets was randomised. The primary outcome was the time to successful intubation. The secondary outcomes were the overall success rates, incidence of dental trauma and ease of intubation. All intubation attempts were assessed by trained assistants. The data were analysed using a multilevel model followed by Tukey’s post hoc test. Results: A total of 68 nurses participated in this study. The time to successful intubation of the McGrath MAC-shaped malleable stylet was significantly shorter than that of the arcuate shape malleable stylet (24.5 (18.0–51.0) s vs 31.5 (21.0–89.0) s, p = 0.005). The overall success rate of the McGrath MAC-shaped malleable stylet was also higher than that of the arcuate shape malleable stylet (p = 0.047). The participants indicated that intubation was easier using the McGrath MAC-shaped malleable stylet compared with the other stylets. Conclusion: The McGrath MAC-shaped malleable stylet, when used by novice intubators, may be an optimal stylet shape for tracheal intubation using the McGrath MAC in cervical immobilisation.

A straightforward way to attain the theoretical capacitance and high rate capability of nickel hydroxide supercapacitors, by utilizing a mesoporous hollow dendritic three-dimensional-nickel (3D-Ni) current collector is proposed. A facile electrodeposition method employing a hydrogen bubble template was chosen for rapid fabrication of the dendritic 3D-nickel structure. After nickel hydroxide was deposited on the hollow 3D-nickel current collector, it exhibited a highest capacitance of 3637 F g−1 at a current density of 1 A g−1, and retained 97 % of capacitance at a high current density of 100 A g−1 with a cycle stability of over 80 % after 10 000 cycles. The enhanced performance could be attributed to the large surface area and high conductivity of the moss-like dendritic 3D-Ni current collector, which allowed direct contact between the active materials and the current collector, and reduced diffusion resistance between the surface of the active materials and the electrolyte. These results not only confirmed a facile fabrication method for high-performance 3D metal nanostructures, but also offer a promising solution for state-of-the-art energy storage systems.

Background Relatively little is known about the effects of mode of delivery on long-term health-related quality-of-life outcomes. Furthermore, no previous study has expressed these outcomes in preference-based (utility) metrics. Methods The study population comprised 2,161 mothers recruited from a prospective population-based study in the East Midlands of England encompassing live births and stillbirths between 32+0 and 36+6 weeks' gestation and a sample of term-born controls. Perinatal data were extracted from the mothers' maternity records. Health-related quality-of-life outcomes were assessed at 12 months postpartum, using the EuroQol Five Dimensions ( EQ-5D) measure with responses to the EQ-5D descriptive system converted into health utility scores. Descriptive statistics and multivariable analyses were used to estimate the relationship between the mode of delivery and health-related quality-of-life outcomes. Results The overall health-related quality-of-life profile of the women in the study cohort mirrored that of the English adult population as revealed by national health surveys. A significantly higher proportion of women delivering by cesarean delivery reported some, moderate, severe, or extreme pain or discomfort at 12 months postpartum than women undergoing spontaneous vaginal delivery. Multivariable analyses, using the Ordinary Least Squares estimator revealed that, after controlling for maternal sociodemographic characteristics, cesarean delivery without maternal or fetal compromise was associated with a significant EQ-5D utility decrement in comparison to spontaneous vaginal delivery among all women (−0.026; p = 0.038) and among mothers of term-born infants (−0.062; p < 0.001). Among mothers of term-born infants, this result was replicated in models that controlled for all maternal and infant characteristics (utility decrement of −0.061; p < 0.001). The results were confirmed by sensitivity analyses that varied the categorization of the main exposure variable (mode of delivery) and the econometric strategy. Conclusions Among mothers of term-born infants, cesarean delivery without maternal or fetal compromise is associated with poorer long-term health-related quality of life in comparison to spontaneous vaginal delivery. Further longitudinal studies are needed to understand the magnitude, trajectory, and underpinning mechanisms of health-related quality-of-life outcomes following different modes of delivery.

Lithium (Li)-ion batteries (LIB) have governed the current worldwide rechargeable battery market due to their outstanding energy and power capability. In particular, the LIB's role in enabling electric vehicles (EVs) has been highlighted to replace the current oil-driven vehicles in order to reduce the usage of oil resources and generation of CO2 gases. Unlike Li, sodium is one of the more abundant elements on Earth and exhibits similar chemical properties to Li, indicating that Na chemistry could be applied to a similar battery system. In the 1970s-80s, both Na-ion and Li-ion electrodes were investigated, but the higher energy density of Li-ion cells made them more applicable to small, portable electronic devices, and research efforts for rechargeable batteries have been mainly concentrated on LIB since then. Recently, research interest in Na-ion batteries (NIB) has been resurrected, driven by new applications with requirements different from those in portable electronics, and to address the concern on Li abundance. In this article, both negative and positive electrode materials in NIB are briefly reviewed. While the voltage is generally lower and the volume change upon Na removal or insertion is larger for Na-intercalation electrodes, compared to their Li equivalents, the power capability can vary depending on the crystal structures. It is concluded that cost-effective NIB can partially replace LIB, but requires further investigation and improvement. [ABSTRACT FROM AUTHOR]

A 50-year-old Korean man had an erythematous patch on the left side of his chest since birth (Fig. 1). We first regarded this lesion as nevus flammeus because of the resemblance of the lesion to an erythematous patch that blanched with pressure. Physical examination revealed an 8×5 cm erythematous patch with a central profuse sweating zone surrounded by a flame-like non-sweating zone (Fig. 2). The patch was sharply demarcated from the normal skin. Sweating was evoked by physical exercise or emotional stress. There was no history of pain or tenderness for the lesion. The patient had no history of any other vascular disease. Histopathologic examination of the central zone showed an increased number of eccrine glands in the mid and deep dermis. Some dilated vascular channels that were not associated with the eccrine glands were present in the upper dermis and subcutaneous tissue (Fig. 3). Immunohistochemical stain with anti-factor VIII-related antigen showed reactivity on the endothelia of the vascular elements which were not associated with eccrine glands in the upper dermis. Histopathologic examination of the surrounding zone showed non-specific findings, except for the dilated vascular channels in the upper dermis. [ABSTRACT FROM AUTHOR]

The Front Cover shows the porous dendrite structure of CuCx–Cu and NiCxNi that can be used as cost‐efficient bi‐functional catalysts instead of Pt and RuO2 catalysts in Zn–air batteries. Although many research efforts have been devoted to developing alternative electrocatalysts to noble‐metal catalysts, the obtained catalysts are only highly active for either the oxygen reduction reaction (ORR) or the oxygen evolution reaction (OER). By introducing a stable metal‐carbide layer on a dendritic metal structure, we managed to prepare a catalyst with a high catalytic surface and an appropriate oxygen binding energy that can be use as bifunctional catalyst in Zn–air batteries. More information can be found in the Communication by Kim et al. on page 4203 in Issue 24, 2018 (DOI: 10.1002/cssc.201802122). [ABSTRACT FROM AUTHOR]
