Authors: Ge Zhixin , Wang Xiangzhi , Huo Yuqiu , Fang Chaohe 
Published: August 2018

AbstractThe flower‐like NiMnO3/Ni(OH)2 growing on multifunctional nickel foam is designed for the first time though a facile, eco‐friendly and straightforward hydrothermal method, in which nickel foam acts as substrate, reductant and the nickel resource. The concentration of bivalent nickel ion plays a key role for the component and capacitive performance of composite. Without outside nickel resource, NiMnO3 are obtained, and their specific capacitance is 750 F g−1 at the current density of 1 mA cm−2. Under the high consistence of bivalent nickel ion, the flower‐like NiMnO3/Ni(OH)2 is produced. Its specific capacitance is up to 3800 F g−1 at the current density of 1 mA cm−2. Such exceptional capacitive performance is attributed to the unique flower‐like structure, excellent contact of active materials with nickel foam substrate and the synergistic effect of constituents. This method can be extended to the synthesis of other bimetallic oxides and other more extensive composites. And the flower‐like NiMnO3/Ni(OH)2 provides a feasible and potential candidate of practical applications of supercapacitor.

AbstractN‐containing monolithic porous carbon material with dual micro and mesoporous structures was synthesized using an innovative, cheap and easy synthesis route based on the classical resorcinol‐formaldehyde synthesis. A completely chemical, structural and morphological characterization was carried out. The N content in the carbonaceous material was 7.3% and XPS data showed that is present in two different surrounds, as N‐pyrrolic and N‐pyridinic atoms. Is known that, the last one, can acts as a catalyst at surface level in heterogeneous reactions. In addition, using this material, we were able to fabricate lithium‐ion and lithium‐sulfur batteries obtaining high values of discharge capacity and cycle stability and demonstrating the multifunctional character of this carbon in energy storage devices.

AbstractThe hierarchical Zr‐MTW zeolites are prepared using NH4F and HF as mineralizing agents and structure‐directed agent like Gemini‐type surfactant and studied by X‐ray diffraction (XRD), 29Si magic angle spinning nuclear magnetic resonance (29Si MAS NMR), Fourier transform infrared (FTIR) spectroscopy with pyridine, 2,6‐di‐tert‐butylpyridine and CD3CN as probe molecules. Structural characteristics and acid‐base properties of the zeolites depend on concentration of fluorine precursor in the reaction medium (a ratio of Si/F). The hierarchical Zr‐MTW zeolites (included doped with copper) have been tested in ethanol conversion into 1,3‐butadiene by Lebedev method. The symbatical dependence of 1,3‐butadiene productivity with the concentration of Lewis acidic sites determined by FTIR spectroscopy of adsorbed CD3CN is observed. 1.3‐Butadiene selectivity of 68 % with ethanol conversion of 81 % are achieved in the presence of Cu/Zr‐MTW catalyst.

Published: August 2018

AbstractWhile immunotherapy has a tremendous clinical potential to combat cancer, immune responses generated by conventional cancer immunotherapy remain not enough to completely eliminate tumors, mainly due to the tumor's immunosuppressive microenvironment and heterogeneity of tumor immunogenicity. To improve antitumor immune responses and realize personalized immunotherapy, in this report, endogenous tumor antigens (ETAs) that dynamically present on tumor cells are transported to lymph nodes (LNs). Based on the hypothesis that nano Fe3O4 (≈10 nm) could serve as the nanocarrier for transporting ETAs from the tumor to LNs, we wondrously find that Fe3O4 has a tremendous potential to improve cancer immunotherapy, because of its excellent protein‐captured efficiency and LNs‐targeted ability. To ensure the optimal ETAs‐bound efficiency of Fe3O4, a core–shell formulation (denoted as Ce6/Fe3O4‐L) is developed and specific release of Fe3O4 in tumor is enabled. These findings provide a simple and general strategy for boosting cytotoxic T‐cell response and realizing personalized cancer immunotherapy simultaneously.

AbstractThe micro‐supercapacitors are of great value for portable, flexible, and integrated electronic equipments. Here, the large‐scale and integrated asymmetrical micro‐supercapacitor (AMSC) array is fabricated in virtue of the laser direct writing and electrodeposition technology. The AMSC shows the ideal flexibility, high areal specific capacitance (21.8 mF cm−2), and good rate capability. Moreover, its energy density reaches 12.16 µW h cm−2, outperforming most micro‐supercapacitors reported previously. Meanwhile, large‐scale series‐connected AMSCs are integrated on the flexible substrates (e.g., indium tin oxide‐polyethylene terephthalate film), which can power a veriety of the commercial electronics. The combination of AMSCs array, solar cell, and electronic device proves the feasibility for practical application in the portable, flexible, and integrated electronic equipments.

AbstractA closed‐loop “smart” insulin delivery system with the capability to mimic pancreatic cells will be highly desirable for diabetes treatment. This study reports a multiple stimuli‐responsive insulin delivery platform based on an explicit supramolecular strategy. Self‐assembled from a well‐designed amphiphilic host–guest complex formed by pillar[5]arene and a diphenylboronic acid derivative and loaded with insulin and glucose oxidase, the obtained insulin‐GOx‐loaded supramolecular vesicles can selectively recognize glucose, accompanied by the structure disruption and efficient release of the entrapped insulin triggered by the high glucose concentration as well as the in situ generated H2O2 and acid microenvironment during the GOx‐promoted specific oxidation of glucose into gluconic acid. Moreover, such a “smart” supramolecular theranostic nanoplatform is able to function as both a glucose sensor and a controlled insulin delivery actuator. In vivo experiments further demonstrate that this smart supramolecular nanocarrier shows fast response to hyperglycemic circumstances and can effectively regulate the glucose levels in a mouse model of type I diabetes.

AbstractControllable degradation and excellent biocompatibility during/after a lifetime endow emerging transient electronics with special superiority in implantable biomedical applications. Currently, most of these devices need external power sources, limiting their real‐world utilizations. Optimizing existing bioresorbable electronic devices requires natural‐material‐based construction and, more importantly, diverse or even all‐in‐one multifunctionalization. Herein, silk‐based implantable, biodegradable, and multifunctional systems, self‐powered with transient triboelectric nanogenerators (T2ENGs), for real‐time in vivo monitoring and therapeutic treatments of epileptic seizures, are reported. These T2ENGs are of customizable in vitro/in vivo operating life and biomechanical sensitivity via the adjustments of silk molecular size, surface structuralization, and device configuration. Functions, such as drug delivery and structural‐integrity optical readout (parallel to electronic signals), are enabled for localized anti‐infection and noninvasive degradation indication, respectively. A proof‐of‐principle wireless system is built with mobile‐device readout and “smart” treatment triggered by specific symptoms (i.e., epilepsy), exhibiting the practical potential of these silk T2ENGs as self‐powered, transient, and multifunctional implantable bioelectronic platforms.
A Flexible Sulfur‐Enriched Nitrogen Doped Multichannel Hollow Carbon Nanofibers Film for High Performance Sodium Storage

Published: August 2018

AbstractHeteroatom doping is regarded as a promising method to enhance the sodium storage performance of carbon materials. In this work, a sulfur‐enriched N‐doped multichannel hollow carbon nanofiber (denoted as S‐NCNF) film is prepared through electrospinning technology and heat treatment with sublimed sulfur as the flexible anode for sodium ion batteries (NIBs). The S‐NCNF film displays outstanding electrochemical performance, particularly with a high rate capacity (132 mA h g−1 at the current density of 10 A g−1) and remarkable long cycling stability (reversible specific capacity of 187 mA h g−1 at 2 A g−1 over 2000 cycles). The improved sodium storage performance results from the unique 3D structure, abundant defects, and increased interlayer spacing of S‐NCNFs. The density functional theory calculations demonstrate that nitrogenous carbon nanofibers doping with sulfur could not only promote the adsorption of sodium but also favor electrons' transfer. This strategy has been demonstrated as a general process to design free‐standing carbon‐based thin film with other heteroatom doping.

Published: August 2018

AbstractDevelopment of efficient bifunctional oxygen electrocatalysts is urgently needed for high‐performance rechargeable Zn–air batteries. However, sluggish oxygen reduction reaction/oxygen evolution reaction (ORR/OER) kinetics and poor mass transport are two key issues that hinder the performance of Zn–air batteries. Herein, a facile strategy is reported to prepare 3D holey N‐doped graphene (3D HNG) with the aid of molten salts for boosting the performance of ORR/OER‐driven Zn–air batteries. The as‐prepared HNG shows a hierarchical porous framework structure with a 1:1 ratio of pyridinic to graphitic N. Owing to the matched N catalytic active sites and the special pore structure, 3D HNG displays super bifunctional electrocatalytic activity toward both ORR and OER. Specifically, rechargeable Zn–air batteries fabricated with this electrocatalyst show excellent discharge capacity, rechargeability, and round‐trip efficiency. Density functional theory (DFT) computations further reveal that armchair–graphitic N and zigzag–pyridinic N are more favorable for ORR and OER, respectively. By combining these two components, the mixed structure displays the lowest overpotentials of 0.47 and 0.36 V for ORR and OER, respectively, comparable to the theoretical values of Pt and RuO2. This work provides a new strategy for optimizing N‐doped carbon materials for bifunctional oxygen electrocatalysts.

Published: August 2018

AbstractThis 9‐year study (2008–2016) on the Shubenacadie River estuary in Nova Scotia yielded new insight into the only confirmed nursery habitat for the Bay of Fundy population of Striped Bass Morone saxatilis. In 7 of 9 years, the initial large spawning episode occurred between May 16 and June 1, after the accumulation of 11 to 20 degree‐days above 12°C. Most of the spawning occurred within about 3 weeks in May and June but could run into July. Egg abundance at river kilometer (rkm) 25 (measured from the estuary mouth) exceeded 1,000 eggs/m3 after the largest episodes due to the narrow estuary and high numbers of spawners. The pelagic eggs and prefeeding larvae were passively transported up and down the estuary by the strong tide, their distribution highly dependent on salinity. The salt front defined the upstream boundary of the nursery habitat, with the eggs and larvae normally distributed between 0.15‰ and 15‰ (above rkm 10). The abundance of first‐feeding larvae (5–7 mm TL) in the upper estuary (above rkm 25) was highest (>500/m3) during years when May–June was warm and dry and saltwater intrusion was high (above rkm 32). Heavy rain after spawning was an important lethal factor, limiting saltwater intrusion to rkm 25 and increasing the risk of advection of eggs and larvae into Cobequid Bay. During June, a lack of copepod prey caused larvae to fail to grow, suggesting that starvation is an important lethal factor. Growth from July onwards was limited by temperature but not food: mysids were highly abundant and an important prey for young of the year (>15 mm TL). By late August juvenile mean total length was >9 cm in warm summers but <5 cm in cooler years. Juveniles were widely dispersed in the estuary and Cobequid Bay through September; their apparent abundance each year was poorly related to larvae abundance.

Authors: Hirano Tomoya , Mori Shuichi , Kagechika Hiroyuki 
Published: August 2018

AbstractProtein lysine methyltransferases (PKMTs) are epigenetic regulators that modulate gene transcription and physiological functions by catalyzing the post‐translational methylation of specific lysine residues of substrate proteins, such as histones. They are considered to be candidate drugs for the treatment of various diseases, including acute myeloid leukemia, and in the past decade, potent and selective inhibitors of individual PKMTs have been developed. Some are currently under clinical trial. In this review, we will focus on some breakthrough PKMT inhibitors, and discuss chemistry‐based methods available for elucidation of the physiological functions of PKMTs and methylated proteins.

Authors: Srivastava Shashank , Brighu Urmila , Rajput Hansa 
Published: August 2018

AbstractA study was conducted at the Jaipur railway station in Jaipur, India, to give the perspectives of the actual waste management practices there. Required information was collected from the stakeholders by means of semi‐structured questionnaires, individual and group interviews, and recorded, official data regarding waste generation, collection, transportation, and disposal. Further quantitative and compositional analyses were performed by means of surveys and measurements. Field visits were made for collection of waste samples for quantification and for the study of its management. The field data were compiled and analyzed by sorting the waste into different components. It was found that 1.8 tons of solid waste is collected per day, and a considerable percentage of it comprises paper, plastic, and glass. Excluding the inerts, which are irrelevant from the point of view of energy saving and recovery potential, the average moisture content was found to be 3.38%. From the perspective of life cycle analysis, the option of composting or recycling would give savings of 28.33 gigajoules (GJ) per day over landfilling, while combustion would give savings of 2.97 GJ per day in comparison to landfilling. Analysis based on a compositional model gives a heat value of 8,157.87 kilojoules per kilogram, which amounts to 14.68 GJ of energy per day.

Published: August 2018

ABSTRACTObjectivesThe primary aim of this study was to compare the diagnostic accuracy of transvaginal sonography (TVS) with vs without bowel preparation (BP) in detecting the presence of rectosigmoid endometriosis. Secondary objectives were to compare the diagnostic accuracy of the two techniques in estimating infiltration of the submucosa, length of the largest rectosigmoid nodules, distance of the nodules from the anal verge and presence of multifocal disease.MethodsThis was a prospective study of patients with symptoms of pelvic pain for more than 6 months and/or suspicion of endometriosis referred to our institution between October 2016 and April 2018. Participants underwent a first TVS without BP followed by TVS with BP within a time interval of 1 week to 3 months. The examinations were performed independently and blindly by two sonographers. Only patients who underwent laparoscopy within the 6 months following the second ultrasound examination were included. Ultrasound results using the two techniques were compared with surgical and histological findings.ResultsOf the 262 patients included in the study, 118 had rectosigmoid endometriosis confirmed at surgery. There was no significant difference in accuracy between TVS with and that without BP in diagnosing the presence of rectosigmoid endometriosis (93.5% vs 92.3%; P = 0.453). No significant difference was observed in accuracy between TVS with and that without BP in diagnosing submucosal infiltration (88.8% vs 84.6%; P = 0.238) and multifocal disease (97.2% vs 95.2%; P = 0.727) in patients diagnosed sonographically with rectosigmoid endometriosis. The accuracy of TVS with BP was similar to that of TVS without BP in estimating the maximum diameter of the largest nodule (P = 0.644) and the distance between the more caudal rectosigmoid nodule and the anal verge (P = 0.162).ConclusionBP does not improve the diagnostic performance of TVS in detecting rectosigmoid endometriosis and in assessing characteristics of endometriotic nodules.

On the accuracy of linear regression routines in some data mining packages
Authors: McCullough B. D. , Mokfi Taha , Almaeenejad Mahsa 
Published: August 2018

While articles assessing the accuracy of traditional statistical packages are fairly commonplace, data mining software has escaped this important scrutiny. We apply the National Institute of Standards and Technology Statistical Reference Datasets tests for the numerical accuracy of statistical packages to 7 data mining packages: IBM Modeler, KNIME, Orange, Python, RapidMiner, Weka, and XLMiner. We find that one package has an unstable algorithm for the calculation of the sample variance and only two have reliable linear regression routines. Of these two packages that offer analysis of variance, one has a bad algorithm. The accuracy of statistical calculations in data mining packages cannot be taken for granted.This article is categorized under:Algorithmic Development > StatisticsApplication Areas > Data Mining Software Tools
Probing the biological obstacles of nanomedicine with gold nanoparticles
Authors: Li Bin , Lane Lucas A. 
Published: August 2018

Despite massive growth in nanomedicine research to date, the field still lacks fundamental understanding of how certain physical and chemical features of a nanoparticle affect its ability to overcome biological obstacles in vivo and reach its intended target. To gain fundamental understanding of how physical and chemical parameters affect the biological outcomes of administered nanoparticles, model systems that can systematically manipulate a single parameter with minimal influence on others are needed. Gold nanoparticles are particularly good model systems in this case as one can synthetically control the physical dimensions and surface chemistry of the particles independently and with great precision. Additionally, the chemical and physical properties of gold allow particles to be detected and quantified in tissues and cells with high sensitivity. Through systematic biological studies using gold nanoparticles, insights toward rationally designed nanomedicine for in vivo imaging and therapy can be obtained.This article is categorized under:

Use of artificial cavities by Humboldt marten
Authors: Delheimer Matthew S. , Slauson Keith M. , Szykman Gunther Micaela , Zielinski Willliam J. 
Published: August 2018

ABSTRACTMany species of wildlife require cavities in trees as locations for refuge or reproduction. In forests where the availability of cavities has been reduced, artificial cavities may provide surrogate locations. Artificial cavities are typically created using boxes and artificial cavity research has traditionally focused primarily on birds. However, there are numerous cavity‐dependent species of mammals that are of regional and global conservation concern, such as the Humboldt marten (Martes caurina humboldtensis). Martens (Martes spp.) are small mustelids that often use cavities for daily resting and seasonal reproductive activities. During June 2013 to September 2015, we tested an artificial cavity design, modified from a design successfully used for European pine martens (M. martes), for the Humboldt marten in northwestern California, USA. We built and installed 16 artificial cavities (“marten” boxes) in marten‐occupied areas that have been managed for timber production and likely have reduced cavity availability. We monitored each box with a remote‐sensing camera for 2 years to evaluate visitation and use by martens and other cavity‐dependent species. Eleven mammal species visited ≥1 boxes and 4 species entered the box to use it. Martens had the greatest number of box‐use events, several martens used boxes for resting, and ≥1 female marten used a box for reproductive activities. Our results indicate that our boxes may provide artificial cavities for Humboldt martens in forests where natural cavities have been reduced due to timber harvest or severe wildfire. © 2018 The Wildlife Society.

Published: August 2018

AbstractTo review embryonic skull shape and brain anatomy by sonography during late embryonic and early fetal periods. We examined embryos/fetuses of 8–11 weeks between March 2015 and February 2018, the period corresponds to CRL 16–44 mm and also corresponds to late embryonic and early fetal periods by transvaginal and transabdominal sonography. We assessed shape of the skull and intracranial brain vesicles. Additionally, embryonic brain anatomy was also assessed by three-dimensional ultrasound. We found 12 abnormal cases, 5 cases between CRL 16–30 mm and 7 cases between CRL 31–44 mm. We followed all cases between 11 and 13 weeks and confirmed acrania with loss of variable amount of brain tissues. Acrania–Exencephaly–Anencephaly sequence can be diagnosed before 11 weeks. Sonographer should be familiar and proper knowledge of brain embryology and anatomy is key to diagnose.
