2 V, high energy density of 164.13 Wh kg-1 at the power density of 1283.44 Wh kg-1 and good stability with a capacity retention of 95.3% after 5000 charge/discharge cycles at 10 A g-1 . The strategy in this work would provide a new insight in exploring flexible hydrogel electrolyte-based supercapacitor with good sustainability and high energy density for flexible wearable electronic devices.1D photonic crystals (1DPCs) are well known from a variety of applications ranging from medical diagnostics to optical fibers and optoelectronics. However, large-scale application is still limited due to complex fabrication processes and bottlenecks in transferring 1DPCs to arbitrary substrates and pattern creation. These challenges were addressed by demonstrating the transfer of millimeter- to centimeter-scale 1DPC sensors comprised of alternating layers of H3 Sb3 P2 O14 nanosheets and TiO2 nanoparticles based on a non-invasive chemical approach. By depositing the 1DPC on a sacrificial layer of lithium tin sulfide nanosheets and hydrophobizing only the 1DPC by intercalation of n-octylamine via the vapor phase the 1DPC can be detached from the substrate by immersing the sample in water. Upon exfoliation of the hydrophilic sacrificial layer, the freestanding 1DPC remains at the water-air interface. In a second step, it can be transferred to arbitrary surfaces such as curved glass. In addition, the transfer of patterned 1DPCs is demonstrated by combining the sacrificial layer approach with area-resolved intercalation and etching. The fact that the sensing capability of the 1DPC is not impaired and can be modified after transfer renders this method a generic platform for the fabrication of photonic devices.Human faces convey abundant social information. The influence of social information on duration estimation was examined by comparing a cartoon face (CF; social) condition with geometric plane figures, or CFs with internal elements disturbed from their normal position (non-social) condition, and also by comparing a human portrait facing the front (more social interaction) condition with the portrait facing the back (less social interaction) condition. Results showed that in the supra-second range, both CFs and human portraits facing the front led to an underestimation compared with non-social or less social information conditions. In the sub-second range, only portraits facing the front were overestimated compared with those facing the back and with the CFs. These results suggest that in the millisecond range, the biological information conveyed by faces may lead to higher arousal, which may result in accelerated clock speed and overestimation. In the supra-second range, it is possible that attention was diverted by social information, resulting in duration underestimation. Taken together, our results suggest that the different mechanisms were involved in duration perception of social information conveyed by face feature in the sub- and supra-second range.mRNA degradation rate is one of the key stages of gene expression regulation in eukaryotic cells. To date, intertwined processes of post-transcriptional control have been widely investigated, but focused rather on the examination of mechanisms controlling stability of particular protein-coding transcripts. Currently, a wealth of information from structural, biochemical, and high-throughput studies makes it tempting to define general rules governing mRNA stability that could be considered as versatile and valid on a genome-wide scale. Basu et al. analyzed multiple experimental and computational data on Saccharomyces cerevisiae mRNA half-lives as well as on secondary structures and protein-binding sites within transcripts, and collated it with available structures of ribonucleases, that is, enzymes responsible for mRNA degradation. This approach allowed to conclude how particular mRNA features such as lengths of unstructured terminal or internal regions or sequestration into ribonucleoprotein complexes impact half-lives of protein-coding transcripts and to define genome-scale principles of mRNA stability control in yeast.Laparoscopic choledochal cyst excision and hepaticojejunostomy for choledochal in children is performed only at particular institutions because of the technical difficulty. Although choledochal cyst excision and hepaticojejunostomy are feasible, the small working space of infants makes intraabdominal Roux-Y reconstruction technically challenging. A 2-month-old girl diagnosed with a choledochal cyst underwent complete laparoscopic choledochal cyst excision and hepaticojejunostomy, including intraabdominal Roux-Y reconstruction with a 5-mm stapler. EKI-785 purchase After cyst excision, Roux-Y reconstruction was performed in the intraabdominal cavity. Jejunojejunostomy was performed in a side-to-side fashion using a 5-mm stapler, and the entry hole was closed laparoscopically by hand-sewing, along with the mesentery defect. All procedures were performed by laparoscopic surgery. The postoperative course was uneventful, and the patient showed a quick recovery. Using small-diameter instruments, completely laparoscopic procedures for choledochal cyst are feasible.Since the sluggish kinetic process of oxygen reduction (ORR)/evolution (OER) reactions, the design of highly-efficient, robust, and cost-effective catalysts for flexible metal-air batteries is desired but challenging. Herein, bimetallic nanoparticles encapsulated in the N-doped hollow carbon nanocubes (e.g., FeCo-NPs/NC, FeNi-NPs/NC, and CoNi-NPs/NC) are rationally designed via a general heat-treatment strategy of introducing NH3 pyrolysis of dopamine-coated metal-organic frameworks. Impressively, the resultant FeCo-NPs/NC hybrid exhibits superior bifunctional electrocatalytic performance for ORR/OER, manifesting exceptional discharging performance, outstanding lifespan, and prime flexibility for both Zn/Al-air batteries, superior to those of state-of-the-art Pt/C and RuO2 catalysts. X-ray absorption near edge structure and density functional theory indicate that the strong synergy between FeCo alloy and N-doped carbon frameworks has a distinctive activation effect on bimetallic Fe/Co atoms to synchronously modify the electronic structure and afford abundant dual-active Fe/Co-Nx sites, large surface area, high nitrogen doping level, and conductive carbon frameworks to boost the reversible oxygen electrocatalysis.
