Published: August 2018

AbstractCarbon electrode are a low‐cost and great potential strategy for stable perovskite solar cells (PSCs). However, the efficiency of carbon‐based PSCs lags far behind compared with that of state‐of‐the‐art PSCs. The poor interface contact between the carbon electrode and the underlying layer dominates the performance loss of the reported carbon‐based PSCs. In this respect, a sort of self‐adhesive macroporous carbon film is developed as counter electrode by a room‐temperature solvent‐exchange method. Via a simple press transfer technique, the carbon film can form excellent interface contact with the underlying hole transporting layer, remarkably beneficial to interface charge transfer. A power conversion efficiency of up to 19.2% is obtained for mesoporous‐structure PSCs, which is the best achieved for carbon‐based PSCs. Moreover, the device exhibits greatly improved long‐term stability. It retains over 95% of the initial efficiency after 1000 h storage under ambient atmosphere. Furthermore, after aging for 80 h under illumination and maximum power point in nitrogen atmosphere, the carbon‐based PSC retains over 94% of its initial performance.

Published: August 2018

AbstractThe first examples of optically pure 9H‐quinolino[3,2,1‐k]phenothiazine (QPTZ)‐based molecules are reported. The inversion of the nitrogen atom, locked in the QPTZ fragment, is confined with a high‐energy barrier that has allowed the isolation at room temperature of each stereoisomer. Considering the growing necessity in molecular electronics to introduce chiral characteristics within highly efficient molecular fragments, a molecular strategy to generate enantiopure derivatives constructed on the very promising electron rich core QPTZ is provided. As this work aims to report the foundations of the QPTZ chirality, the present findings may open avenues towards the use of this fragment in its optically pure form.
Janus MoSSe Nanotubes: Tunable Band Gap and Excellent Optical Properties for Surface Photocatalysis
Authors: Tang Zhen‐Kun , Wen Bo , Chen Mingyang , Liu Li‐Min 
Published: August 2018

AbstractTransition metal chalcogenides have attracted considerable attention because of their wide applications in solving energy and environmental problems. Here, the electronic structures and optical properties of Janus MoSSe nanotubes are explored by first‐principles calculations. It is shown that the Janus MoSSe nanotubes exhibit versatile electronic properties. All zigzag MoSSe nanotubes exhibit a direct band gap with a good optical absorption. More interestingly, the electronic structure of the armchair MoSSe nanotubes is greatly dependent on the radius. The nanotubes are indirect semiconductors at a small radius of 7.4 Å, and they could gradually become direct semiconductors with the increase of the radius of armchair MoSSe nanotubes. Further, the optical absorption abilities of the armchair MoSSe nanotubes can be further modulated by axial stress. The suitable band gap, lower formation energy, and tunable band gap of the armchair MoSSe nanotubes enable them to have great potential applications for optoelectronics and photocatalysis as low‐dimensional nanomaterials.

AbstractThe exploration of new and efficient energy storage mechanisms through nanostructured electrode design is crucial for the development of high‐performance rechargeable batteries. Herein, black phosphorus quantum dots (BPQDs) and Ti3C2 nanosheets (TNSs) are employed as battery and pseudocapacitive components, respectively, to construct BPQD/TNS composite anodes with a novel battery‐capacitive dual‐model energy storage (DMES) mechanism for lithium‐ion and sodium‐ion batteries. Specifically, as a battery‐type component, BPQDs anchored on the TNSs are endowed with improved conductivity and relieved stress upon cycling, enabling a high‐capacity and stable energy storage. Meanwhile, the pseudocapacitive TNS component with further atomic charge polarization induced by POTi interfacial bonds between the two components allows enhanced charge adsorption and efficient interfacial electron transfer, contributing a higher pseudocapacitive value and fast energy storage. The DMES mechanism is evidenced by substantial characterizations of X‐ray photoelectron spectroscopy and X‐ray absorption fine structure spectroscopy, density functional theory calculations, and kinetics analyses. Consequently, the composite electrode exhibits superior battery performance, especially for lithium storage, such as high capacity (910 mAh g−1 at 100 mA g−1), long cycling stability (2400 cycles with a capacity retention over 100%), and high rate capability, representing the best comprehensive battery performance in BP‐based anodes to date.

AbstractAlloyed metal nanocatalysts are of environmental and economic importance in a plethora of chemical technologies. During the catalyst lifetime, supported alloy nanoparticles undergo dynamic changes which are well‐recognized but still poorly understood. High‐temperature O2–H2 redox cycling was applied to mimic the lifetime changes in model Pt13In9 nanocatalysts, while monitoring the induced changes by in situ quick X‐ray absorption spectroscopy with one‐second resolution. The different reaction steps involved in repeated Pt13In9 segregation‐alloying are identified and kinetically characterized at the single‐cycle level. Over longer time scales, sintering phenomena are substantiated and the intraparticle structure is revealed throughout the catalyst lifetime. The in situ time‐resolved observation of the dynamic habits of alloyed nanoparticles and their kinetic description can impact catalysis and other fields involving (bi)metallic nanoalloys.
Palladium‐Catalyzed γ‐C(sp3)−H Arylation of Thiols by a Detachable Protecting/Directing Group
Authors: Jin Likun , Wang Jianchun , Dong Guangbin 
Published: August 2018

AbstractReported herein is a palladium‐catalyzed, directed γ‐C(sp3)−H arylation of protected thiols. The key is to utilize Michael acceptors as a dual reagent to install a protecting/directing group on thiols by a thiol‐Michael click reaction, and remove it later under basic conditions. The C−H arylation proceeds with high functional‐group tolerance and the deprotected thiols can be further transformed into other sulfur‐containing compounds. This unique mode of activation could open the door for site‐selective functionalization of thiols or other sulfur‐containing compounds at unactivated positions.

AbstractThe geophysical investigations aiming to image the interior of the huge tumulus of Kastas in Amphipolis in northern Greece commenced on November of 2014 and continued sporadically until the first months of 2017. The electrical resistivity tomography (ERT) method was exclusively employed in both conventional and innovative schemes. Due to the immense size of the tumulus, an irregular grid was established on the tumulus whereas regular grids of ERTs were established on a small terrace created by the excavations and at the south extremity. Also, typical two‐dimensional (2D) ERTs carried out to help clarifying the geological and tectonic setting. Kastas tumulus was created by covering a hill with large amounts of transported earth material. In this respect it constitutes a huge human construction. Further, the excavations revealed a unique building containing ancient art masterpieces. The irregular grid on top constitutes the first effort of such an approach to investigate the interior of a tumulus since all known efforts have been implemented employing regular grids. Consequently, a three‐dimensional (3D) smoothness constrained inversion algorithm was modified. At first, the irregularly placed electrode locations had to fit in a finite element forward solver having particular specifications. Further, the hexahedral elements of the created mesh were manipulated to cope with neighbouring electrode positions in order to make a less dense grid. Finally, a so called ‘nudging’ process was followed to merge closely positioned electrodes belonging to different, branching, 2D data acquisition lines. The geophysical imaging helped clarify the geological and tectonic structure of Kastas. Further, it yielded several findings some of them being interpreted as natural features and some others as probable manmade. The latter comprise the targets of future excavations.

AbstractA pair of interconvertible stereoisomers of imide‐fused corannulene derivatives was mixed with C60, which resulted in cocrystallization into a 1:1 segregated packing motif through concave–convex π–π interactions. Only one conformation was observed in the cocrystal owing to guest‐induced conformational switching. The 1D assemblies of the complex showed promising applications in organic electronics.

Analyse des Tausalzeintrags in Fahrbahndeckenbetone mit neuartiger Prüftechnik
Authors: Weise Frank , Millar Steven , Wilsch Gerd 
Published: August 2018

AbstractIn den letzten Jahren sind im deutschen Bundesautobahnnetz vermehrt AKR‐Schäden an Betonfahrbahndecken aufgetreten. Ursächlich hierfür ist die Verwendung alkaliempfindlicher Gesteinskörnung. Dies führt bei gleichzeitiger Anwesenheit von Wasser infolge der Exposition der Fahrbahndecke und des alkalischen Milieus durch den Einsatz alkalireicher Portlandzemente bei der Betonherstellung zu einer Alkali‐Kieselsäure‐Reaktion (AKR). Zusätzlich wird der AKR‐Schädigungsprozess in Betonfahrbahndecken durch den externen Tausalzeintrag (primär NaCl) im Winter begünstigt. Vor diesem Hintergrund kommt der Ermittlung des Tausalzeintrags in den Fahrbahndeckenbeton eine große Bedeutung zu.Die Analyse des Tausalzeintrags erfolgte bisher ausschließlich nasschemisch an gemahlenen Bohrkernsegmenten. Nachteilig sind hierbei der relativ hohe prüftechnische Aufwand und die eingeschränkte Ortsauflösung. Der alternative Einsatz von LIBS (Laser‐induced breakdown spectroscopy) eröffnet in diesem Kontext neue Möglichkeiten. So wird in diesem Beitrag anhand von Bohrkernen aus einem repräsentativen AKR‐geschädigten BAB‐Abschnitt exemplarisch die Vorgehensweise bei der LIBS‐Analyse zur Ermittlung der Na‐ und Cl‐Verteilung an vertikalen Schnittflächen von Bohrkernen aufgezeigt. Da der Tausalzeintrag primär über den Zementstein erfolgt, wurde der verfälschende Na‐Grundgehalt der Gesteinskörnung mittels eines Ausschlusskriteriums (Ca‐Gehalt) eliminiert. Vergleichend durchgeführte Cl‐Mappings mit Mikroröntgenfluoreszenzanalyse sowie nasschemische Analysen belegen die Güte der durchgeführten LIBS‐Messungen. Allerdings bedarf es bei der quantitativen Ermittlung des Natriumgehaltes in der Betonfahrbahndecke noch weitergehender Untersuchungen.
Making complex prediction rules applicable for readers: Current practice in random forest literature and recommendations

Published: August 2018

AbstractIdeally, prediction rules should be published in such a way that readers may apply them, for example, to make predictions for their own data. While this is straightforward for simple prediction rules, such as those based on the logistic regression model, this is much more difficult for complex prediction rules derived by machine learning tools. We conducted a survey of articles reporting prediction rules that were constructed using the random forest algorithm and published in PLOS ONE in 2014–2015 in the field “medical and health sciences”, with the aim of identifying issues related to their applicability. Making a prediction rule reproducible is a possible way to ensure that it is applicable; thus reproducibility is also examined in our survey. The presented prediction rules were applicable in only 2 of 30 identified papers, while for further eight prediction rules it was possible to obtain the necessary information by contacting the authors. Various problems, such as nonresponse of the authors, hampered the applicability of prediction rules in the other cases. Based on our experiences from this illustrative survey, we formulate a set of recommendations for authors who aim to make complex prediction rules applicable for readers. All data including the description of the considered studies and analysis codes are available as supplementary materials.
A comparison of relative survival and cause‐specific survival methods to measure net survival in cancer populations

Published: August 2018

AbstractBackgroundAccurate cancer survival statistics are necessary for describing population‐level survival patterns and measuring advancements in cancer care. Net cancer survival is measured using two methods: cause‐specific survival (CSS) and relative survival (RS). Both are valid methodologies for estimating net survival and are used widely in medical research. In these analyses, we compare CSS to RS at selected cancer sites.MethodsUsing data from 18 SEER registries between 2000 and 2014, five‐year RS and CSS estimates were generated overall as well as by age groups and by sex. To assess how closely the two survival methods corresponded, net survival percent difference was calculated with the following formula: ((RS‐CSS)/RS)*100.ResultsDiscrepancies between estimates obtained from CSS and RS methods varied with cancer site and age, but not by sex. In most cases, CSS was greater than RS, but cancers with available early screening and high survival rate had higher RS than CSS. Net survival percent differences were small in children and adolescents and young adults, and large in adults over the age of 40.ConclusionsWhile both CSS and RS aim to quantify net survival, the estimates tend to differ due to the biases present in both methodologies. Error when estimating CSS most frequently stems from misclassification of cause of death, whereas RS is subject to error when no suitable life tables are available. Appropriate use of CSS and RS requires a detailed understanding of the characteristics of the disease that may lead to differences in the estimates generated by these methods.

AbstractSeptins constitute a novel class of cytoskeletal proteins. Budding yeast septins self‐assemble into non‐polar filaments bound to the inner plasma membrane through specific interactions with l‐α‐phosphatidylinositol‐4,5‐bisphosphate (PI(4,5)P2). Biomimetic in vitro assays using giant unilamellar vesicles (GUVs) are relevant tools to dissect and reveal insights in proteins–lipids interactions, membrane mechanics and curvature sensitivity. GUVs doped with PI(4,5)P2 are challenging to prepare. This report is dedicated to optimize the incorporation of PI(4,5)P2 lipids into GUVs by probing the proteins–PI(4,5)P2 GUVs interactions. We show that the interaction between budding yeast septins and PI(4,5)P2 is more specific than using usual reporters (phospholipase Cδ1). Septins have thus been chosen as reporters to probe the proper incorporation of PI(4,5)P2 into giant vesicles. We have shown that electro‐formation on platinum wires is the most appropriate method to achieve an optimal septin–lipid interaction resulting from an optimal PI(4,5)P2 incorporation for which, we have optimized the growth conditions. Finally, we have shown that PI(4,5)P2 GUVs have to be used within a few hours after their preparation. Indeed, over time, PI(4,5)P2 is expelled from the GUV membrane and the PI(4,5)P2 concentration in the bilayer decreases.
Laminar specific gene expression reveals differences in postnatal laminar maturation in mouse auditory, visual, and somatosensory cortex

Published: August 2018

AbstractProper formation of laminar structures in sensory cortexes is critical for sensory information processing. Previous studies suggested that the timing of neuronal migration and the laminar position of cortical neurons differ among sensory cortexes. How they differ during postnatal development has not been systematically investigated. Here, identifying laminas using transcription factors, we examined postnatal changes in neuronal density and distribution in presumptive primary auditory (ACx), visual (VCx), and somatosensory cortexes (SCx) in a strain of mice using immunofluorescence techniques. Development of laminar thickness and its cortical proportion differed among the sensory cortexes. Layers 2–4 defined by Cut‐like homeobox 1 (Cux1)‐expressing neurons were narrower, and layer 5 was wider in ACx compared to those in VCx or SCx, while Forkhead‐box protein P2 (Foxp2)‐defined layer 6 was wider in SCx than the other two sensory cortexes throughout postnatal development. Meanwhile, thalamocortical input layers identified by Cux1‐expressing neurons formed later in ACx than in the other two cortical regions. The cell densities of ETS‐related protein 81‐expressing neurons increased in both lower and upper layers but at distinct timing, while those of COUP‐TF‐interacting protein 2 expressing neurons in the lower layers changed bidirectionally (i.e., increased or decreased) both in layer‐ and cortical region‐specific manners. Foxp2‐expressing cells in layer 6 distributed differently and declined at different timing among the sensory cortexes. Overall, we demonstrate that the maturational timing of lamina differs among the sensory cortexes and that postnatal age‐dependent changes in neuronal distribution are unique to each of the sensory cortexes.

AbstractThe development of medial temporal lobe circuits is critical for subsequent learning and memory functions later in life. The present study reports the expression of progesterone receptor (PR), a powerful transcription factor of the nuclear steroid receptor superfamily, in Cajal‐Retzius cells of the molecular layer of the dentate gyrus of rats. PR was transiently expressed from the day of birth through postnatal day 21, but was absent thereafter. Although PR immunoreactive (PR‐ir) cells did not clearly express typical markers of mature neurons, they possessed an ultrastructural morphology consistent with neurons. PRir cells did not express markers for GABAergic neurons, neuronal precursor cells, nor radial glia. However, virtually all PR cells co‐expressed the calcium binding protein, calretinin, and the glycoprotein, reelin, both reliable markers for Cajal‐Retzius neurons, a transient population of developmentally critical pioneer neurons that guide synaptogenesis of perforant path afferents and histogenesis of the dentate gyrus. Indeed, inhibition of PR activity during the first two weeks of life impaired adult performance on both the novel object recognition and object placement memory tasks, two behavioral tasks hypothesized to describe facets of episodic‐like memory in rodents. These findings suggest that PR plays an unexplored and important role in the development of hippocampal circuitry and adult memory function.
