Tree-ring response to the 1995 Mw 7.2 Kobe earthquake, southwest Japan
Authors: Lin Sujian , Lin Aiming
Published: November 2017

Abstract. The 1995 Mw 7.2 Kobe earthquake produced an ~ 18 km-long surface rupture zone with a maximum right-lateral displacement of ~ 1.8 m along the pre-existing active Nojima Fault in southwest Japan. Field investigations showed that the co-seismic surface ruptures caused severe damage to trees, some of which survived the disaster during the past twenty years along the co-seismic fault scarp. Analysis of tree-rings from the trunk of a 46-year-old Beech tree (Fagus crenata Blume) revealed that the tree was cracked by earthquake-induced damage and that the tree-rings grown during the five-year period after the 1995 earthquake become sharply narrower in width compared to those grown before the earthquake. Our findings indicate that the earthquake damaged trees along the co-seismic fault scarp and hindered the growth of tree-rings by severing the roots. Thus, the results support the idea that older trees growing along or around fault zones can be used for identifying seismic fault events and for dendrochronological studies related to geomorphological processes.
Brief communication: Multiscaled solitary waves
Authors: Derzho Oleg G.
Published: November 2017

Abstract. It is analytically shown how competing nonlinearities yield multiscaled structures for internal solitary waves in stratified shallow fluids. These solitary waves only exist for large amplitudes beyond the limit of applicability of the Korteweg–de Vries (KdV) equation or its usual extensions. The multiscaling phenomenon exists or does not exist for almost identical density profiles. The trapped core inside the wave prevents the appearance of such multiple scales within the core area. The structural stability of waves of large amplitudes is briefly discussed. Waves of large amplitudes displaying quadratic, cubic and higher-order nonlinear terms have stable and unstable branches. Multiscaled waves without a vortex core are shown to be structurally unstable. It is anticipated that multiscaling phenomena will exist for solitary waves in various physical contexts.
Subglacial drainage patterns of Devon Island, Canada: Detailed
comparison of river and tunnel valleys
Authors: Grau Galofre Anna , Jellinek A. Mark , Osinski Gordon R. , Zanetti Michael , Kukko Antero
Published: November 2017

Abstract. Tunnel valleys are bedrock incised channels (N-channels) attributed to erosion by meltwater in subglacial conduits. They exert a major control on meltwater accumulation at the base of ice sheets, serving as drainage pathways and modifying ice flow rates. Exposed relict tunnel valleys offer a unique opportunity to study the geomorphologic fingerprint of subglacial erosion and characterize the geometry of individual channels. In this study we present field and remote sensing observations of exposed tunnel valleys on Devon Island (Canadian Arctic Archipelago), including descriptions of tunnel valley cross sections and longitudinal profiles, as well as network morphology, to describe the spatial extend and distinctive characteristics of subglacial drainage systems. We use field-based GPS measurements of tunnel valley longitudinal profiles, along with stereo imagery derived Digital Surface Models (DSM), and novel kinematic mobile LiDAR data to establish a quantitative comparison of tunnel and river valleys in our field study area. Tunnel valleys typically cluster in groups of 5-10 channels throughout the island, oriented radially with respect to active or former ice margins. We identify departures in tunnel valley direction from local topographic gradients and undulations in the longitudinal profiles. We also observe that the width of first order tributaries is one to two orders of magnitude larger than in river systems, and remarkably constant downstream. These distinctive aspects of tunnel valley morphology are similar among the different locations characterized in the study. Furthermore, our findings are consistent with expectations of flow driven by gradients in effective water pressure related to variations in ice thickness. Our field and remote sensing observations provide a rigorous way to distinguish tunnel and river valleys in local and regional topography data that revisits well-established field identification guidelines. Distinguishing river and tunnel valleys in topographic data is critical for understanding the emergence, geometry and extent of channelized subglacial drainage systems. The final aim of this study is to facilitate the identification of tunnel valley networks throughout the globe by using remote sensing techniques, which will improve the detection of these systems and help to build understanding of the mechanics of subglacial channelized drainage.
Student Absences and Academic Achievement
Authors: Eide Eric R , Fillmore Ian , Showalter Mark H
Published: November 2017

We use nationally representative data on students in the United States who are enrolled in grades 7-12 together with the statistical techniques of Ordinary Least Squares (OLS), Quantile Regression (QR), and Instrumental Variables (IV) to explore how various types of student absences are related to test scores. Using a variable that measures total absences, the OLS results suggest that missing two weeks of school is associated with a one-tenth standard deviation reduction in math score. Estimates vary widely when allowing the relation to differ by type of absence and by quantile of the conditional test score distribution. Using absence due to injury as an IV for total absence leads to larger coefficients than OLS.

Published: November 2017

Introduction: We evaluated the efficacy and safety of single lower calyceal tract combined with flexible nephroscopy for the management of staghorn renal stones by percutaneous nephrolithotomy.Methods: The medical records of patients who underwent percutaneous nephrolithotomy for the management of staghorn stones were analyzed. We included patients aged >18 years, while patients with incomplete data and renal anatomical anomalies were excluded from the study. Stone-free rate, postoperative complications, procedure duration, fluoroscopy time, and length of hospitalization were recorded. Postoperative outcomes were evaluated by non-contrast computed tomography scan 4–6 weeks after the operation. Stonefree status was defined as the absence of residual stones >4 mm. Results: The study cohort consisted of 103 consecutive patients. Stonefree rate was 65.0%. No complications were observed in 69.9% of the cases; most postoperative complications were Grade 1 (13.6%) and 2 (10.7%). Five patients (4.9%) suffered a Grade 3a complication and another patient (1.0%) suffered a Grade 3b complication.Conclusions: Percutaneous nephrolithotomy through a single lower calyceal tract combined with flexible nephroscopy can be a valuable treatment option for the treatment of staghorn calculi, providing efficacy and safety. Nevertheless, the present study is limited by both its retrospective nature and being conducted at a single centre and, thus, proper prospective studies with head-on comparisons are needed to prove or disprove the advantages and disadvantages of either approach.
Treatment effectiveness in interstitial cystitis/bladder pain syndrome: Do patient perceptions align with efficacy-based guidelines?
Authors: Lusty Avril , Kavaler Elizabeth , Zakariasen Kay , Tolls Victoria , Nickel J. Curtis
Published: November 2017

Introduction: We sought to determine if patients’ perceptions of success or failure of interstitial cystitis/bladder pain syndrome (IC/ BPS) therapies proposed in treatment guidelines align with the evidence from available clinical trial treatment data.Methods: A total of 1628 adult females with a self-reported diagnosis of IC completed a web-based survey in which patients described their perceived outcomes with the therapies they were exposed to. Previously published literature, used in part to develop IC/ BPS guidelines, provided the clinical trial data outcomes. Patientreported outcomes were compared to available clinical trial outcomes and published treatment guidelines.Results: Based on patient perceived outcomes (benefit:risk ratio), the most effective treatments were opioids, phenazopyridine, and alkalizing agents, with amitriptyline and antihistamines reported as moderately effective. The only surgical procedure with any effectiveness was electrocautery of Hunner’s lesions. In order of efficacy reported in the literature, the therapies for IC/BPS with predicted superior outcomes should be: cyclosporine A, amitriptyline, hyperbaric oxygen, pentosan polysulfate plus subcutaneous heparin, botulinum toxin A plus hydrodistension, and L-arginine. While some of the guideline recommendations aligned with patientreported effectiveness data, there was a general disconnect between guidelines and effectiveness reported in clinical practice.Conclusions: There is a disconnect between real-world patient perceived effectiveness of IC/BPS treatments compared to the efficacy reported from clinical trial data and subsequent guidelines developed from this efficacy data. Optimal therapy must include the best evidence from clinical research, but should also include real-life clinical practice implementation and effectiveness.
Do antibiotics decrease prostate-specific antigen levels and reduce the need for prostate biopsy in type IV prostatitis? A systematic literature review

Published: November 2017

Introduction: Inflammation of the prostate can be a cause of elevated prostate-specific antigen (PSA) in men referred for suspected prostate cancer. This systematic review assesses the evidence for antibiotic therapy in patients with type IV (asymptomatic) prostatitis with regard to reduction of PSA levels and discrimination between prostate cancer and inflammation.Methods: MEDLINE, EMBASE, and the Cochrane registry were searched for papers reporting on cohorts of men with elevated PSA and type IV prostatitis that were treated with antibiotics.Results: The search yielded 160 papers, of which 11 met the inclusion criteria: two randomized trials and nine cohort studies. In total, the studies reported on 1011 patients with type IV prostatitis, of whom 926 were treated with antibiotics. PSA normalization was seen after antibiotic treatment in 33.2% of patients (95% confidence interval [CI] 24.9‒42.8). Meta-analysis of the randomized trials did not demonstrate a higher likelihood of PSA normalization in the antibiotics arm as compared to the control arm (odds ratio [OR] 1.27; 95% CI 0.58–2.76; p=0.553). Four studies performed prostate biopsies in all patients. Although three of these studies demonstrated lower prevalence of prostate cancer in patients in whom PSA had normalized, meta-analysis failed to show a statistically significant difference (OR 0.39; 95% CI 0.06–2.49; p=0.319).Conclusions: The available evidence does not support antibiotic therapy for differentiation between benign and malignant cause of elevated PSA in men with type IV prostatitis.

Published: November 2017

Testicular oligometastasis secondary to prostate cancer is rare. We present a case where a patient with locally advanced prostate cancer was treated with high-dose external beam radiotherapy and two years of androgen-deprivation therapy, followed by intermittent androgen suppression. Three and a half years after initial diagnosis, he was found to have a painless testicular mass. Orchiectomy was performed and histopathology demonstrated metastatic prostatic adenocarcinoma. He remains in clinical remission on intermittent androgen suppression eight years following initial treatment, and over four years after presentation with testicular metastasis.

Soft tissue perineuriomas are rare but benign tumours that are composed of peripheral nerve sheath and are most commonly located in the extremity. Diagnosis is confirmed by the immunohistochemical and ultrastructural features of the tumour. Paratesticular location is extremely rare; so far, only one case is reported. Herein, we report a second case of perineurioma in a 16-year-old male in the paratesticular region.
YouTube viewers in diapers: An exploration of factors associated with amount of toddlers’ online viewing
Authors: Elias Nelly , Sulkin Idit
Published: November 2017

Recent studies show that television is no longer the primary choice for screen viewing among very young children, having been surpassed by online viewing platforms, among which YouTube is dominant. YouTube’s simple user interface, that allows even toddlers to proceed to the next item on the playlist and affords them easy access to their favorite videos, has been suggested as the key to its popularity with very young audiences. On the other hand, young children’s lack of technical, critical and social skills renders them particularly vulnerable to commercial and age-inappropriate content that they might encounter online. In this rapidly changing media environment, in which more and more children begin online activity at a much younger age, it is crucial to evaluate the amount of young children’s online viewing and the factors that determine their viewing habits. Consequently, the present study aimed at identifying the profile of toddler online viewers based on child, parent and family-related characteristics and revealing predictors that might explain higher online exposure. The study, based on a face-to-face survey conducted in Israel among 289 parents of toddlers aged 18-36 months, reveals that online viewing has become normative behavior among toddlers and emphasizes how deeply online viewing is integrated into the basic daily routine of parents with very young children who use online viewing platforms to fulfill a wide range of their childrearing needs.
Looking beyond swiping and tapping: Review of design and methodologies for researching young children’s use of digital technologies
Authors: Miller Jennifer L. , Paciga Kathleen A. , Danby Susan , Beaudoin-Ryan Leanne , Kaldor Tamara
Published: November 2017

We conducted a systematic, in-depth literature review to examine the research around digital technology and media technologies for young children. We were particularly interested in understanding the range of research designs and specifics about elements of the method employed for researching digital technologies with young children (i.e., birth to 5 years). We focused precisely on this age group because it overlaps with the early childhood education period, and recent policy statements that focus on technology usage in young children and offer varying recommendations for children whose chronological age falls in the first five years of life. We completed a detailed analysis of 60 studies published 2011 to 2015; our synthesis focused on describing the research designs, and several specifics of the research method in each primary source: child demographics, the materials used in the research tasks, and the social and cognitive nature of tasks that children engaged in throughout each empirical study. Our findings provide insight for a framework that captures the complex interplay between child development, learning, lived experiences, and social contexts that surround the use of digital technologies.
A Liberal Anti-Porn Feminism?
Authors: Davies Alex ,   Department of Philosophy, Florida State University
Published: November 2017

In the 1980s and 1990s, attempts were made to create U.S. legislation that would make it possible to sue the makers and distributors of pornography for doing so. One defence of such legislation was and is the free speech argument against pornography. Philosophers Rae Langton, Jennifer Hornsby, and Caroline West have supposed that this argument can function as a liberal defence of the legislation: in particular, a defence based on the value of women’s liberty. I argue that the free speech argument cannot be so used. The legislation is, to some extent, self-defeating insofar as it is understood in terms acceptable to a fairly standard kind of liberal. This becomes apparent when we consider the value pornography can have for women, which we can see if we consider what female makers, distributors, and consumers of pornography have to say about why they make, distribute, and consume it.
Design Generativo de Superfícies: uma análise do uso de programação para o desenvolvimento de estamparia
Authors:   Universidade Estadual Paulista, Laranjeira Mariana Araujo , Marar João Fernando , Paschoarelli Luis Carlos , Landim Paula da Cruz
Published: November 2017

O uso de linguagem de programação no processo de desenvolvimento de design traz uma nova perspectiva aos métodos ao possibilitar que o designer, ao invés de criar e desenhar, informe parâmetros à um sistema computacional para que o mesmo atenda às necessidades do projeto. Em adição a isso, os princípios dos sistemas generativos podem ser expressivos, suscitando em ferramentas de criação que extravasam a limitação da imaginação e fornecem soluções dinâmicas e customizadas. A modelagem generativa considera para a concepção da forma o uso dos princípios de geometria alinhados com a programação de dados e as características de sistemas complexos que apresentam emergência e auto-organização. Nesse cenário, o presente artigo apresenta e discute as relações do design paramétrico e generativo com o design de superfícies estampadas. Como resultado, é apresentado como essa área pode se beneficiar dos novos métodos e evoluir suas práticas projetuais na criação do design de moda.

Este artigo é o registro de uma prática experimental realizada sobre substrato têxtil, que objetivou a manipulação de superfícies em projetos mutáveis, flexíveis e transitórios. O conceito foi construído a partir de reflexões sobre as formas tradicionais de uso dos objetos, em situações de privacidade, e a interação entre interior e exterior. O método construtivo utilizado foi o Miura-ori e o processo experimentado foi o da plissagem artesanal. Como resultado, apresentamos o objeto “membrana” que, de maneira sensorial e poética, foi manuseado em diferentes situações e formatos, comprovando a possível transitoriedade das superfícies têxteis.

Published: November 2017

O objetivo deste estudo é analisar o processo de desenvolvimento de produtos de moda, identificar suas principais atividades e compreender como tais atividades estão distribuídas entre os elos da cadeia de valor. O referencial teórico clássico de processos organizacionais nos quais atividades são intercaladas por filtros que selecionam quais projetos devem evoluir, ser revisados ou cancelados, conforme critérios estabelecidos para, ao final, gerar um portfólio de produtos que serão lançados. Estes processos são análogos aos de desenvolvimento de produtos no mercado de moda, onde produtos são desenvolvidos em etapas e filtrados para formar uma coleção. À luz do quadro teórico, foram mapeados processos de desenvolvimento de produtos que permeiam a relação entre dois elos da cadeia: confecção e marca. Esta análise permitiu compreender a interdependência entre estes dois elos e os seus principais papéis de cada parte no processo de desenvolver e selecionar quais produtos serão efetivamente comercializados.

Antibodies to Bordetella pertussis antigens in maternal and cord blood pairs: a Thai cohort study
Authors: Wanlapakorn Nasamon , Thongmee Thanunrat , Vichaiwattana Preeyaporn , Leuridan Elke , Vongpunsawad Sompong , Poovorawan Yong
Published: November 2017

Background

Pertussis is a vaccine-preventable disease, yet an increasing incidence of pertussis occurs in many countries. Thailand has a long-standing pertussis vaccination policy, therefore most expectant mothers today had received vaccines as children. The resurgence of pertussis among Thai infants in recent years led us to examine the pre-existing antibodies to Bordetella pertussis antigens in a cohort of 90 pregnant women.

Methods

We evaluated the IgG to the Pertussis toxin (PT), filamentous hemagglutinin (FHA) and pertactin (PRN) in maternal and cord blood sera using commercial enzyme-linked immunosorbent assays (ELISA).

Results

When values of >10 IU/ml were accepted as potential protective concentrations, we found that the percentages of unprotected infants were 73.3%, 43.3% and 75.5% for anti-PT, anti-FHA and anti-PRN IgG, respectively.

Discussion

These results may explain the susceptibility for pertussis among newborn infants in Thailand and support the requirement for a pertussis booster vaccine during pregnancy, which may contribute to the passive seroprotection among newborns during the first months of life.
Transient Variations in Glacial Mass Near Upernavik Isstrøm (West Greenland) Detected by the Combined Use of GPS and GRACE Data
Authors: Zhang Bao , Liu Lin , Khan Shfaqat Abbas , van Dam Tonie , Zhang Enze , Yao Yibin
Published: November 2017

The continuously operating Global Positioning System (GPS) sites mounted on bedrock around the coast of Greenland provide important geodetic data sets to quantify the solid Earth's response to historical and present‐day ice mass variations. However, the presence of colored noise and irregular seasonal signals makes it difficult to detect transient changes in GPS time series. Here we apply the multichannel singular spectral analysis to the combination of GPS data and Gravity Recovery and Climate Experiment (GRACE) data so that we can identify and fully utilize the spatial correlations from these two independent data sets. Using the GPS and GRACE data near Upernavik Isstrøm in West Greenland as an example, we demonstrate that this method successfully detects two transient signals in ice mass variations during 2008 and 2014. Our forward modeling of loading displacements due to changes in surface mass balance (SMB) and ice dynamics suggests that the transient change starting in mid‐2008 was due to the combined contributions from dynamically induced mass loss and SMB. The transient change starting in mid‐2011 was mainly due to ablation. Specifically, the ice melted more in 2012 and less in 2013 with little contribution from anomalies in accumulation.

Precise knowledge of the melting temperatures of iron, nickel, and their alloys at pressures of the deep Earth would allow us to better constrain the parameters used for the Earth's heat budget and dynamics. However, melting curves of transition metals at pressures approaching 100 GPa and above are still controversial. To address this issue, we report new data on the melting temperature of nickel in a laser‐heated diamond anvil cell up to 100 GPa obtained by X‐ray absorption spectroscopy (XAS), a technique rarely used at such conditions. We couple this for the first time to ex situ analysis of the sample, providing a further validation of the melting criterion adopted here. Finally, a Simon‐Glatzel fit to the melting data obtained in this work, combined with those obtained in the most recent X‐ray diffraction experiments, gives
, defining the most up‐to‐date X‐ray‐determined melting curve for Ni. This result confirms that Ni could be ignored in the discussion on melting properties and thermal profile of the Earth's core, as it should affect the Fe melting point by only 10–20 K at 90 GPa.

During the formation of the Earth's core, the segregation of metallic liquids from silicate mantle should have left behind evident geochemical imprints on both the mantle and the core. Some distinctive geochemical signatures of the mantle‐derived rocks likely own their origin to the metal‐silicate differentiation of the primitive Earth, setting our planet apart from undifferentiated meteorites as well as terrestrial planets or moons isotopically and compositionally. Understanding the chemical evolution of terrestrial planetary bodies requires knowledge on properties of both liquid iron alloys and silicates equilibrating under physicochemical conditions pertinent to the deep magma ocean. Here we report experimental and computational results on the pressure‐induced structural evolution of iron‐nickel liquids alloyed with carbon. Our X‐ray diffraction experiments up to 7.3 gigapascals (GPa) demonstrate that Fe‐Ni (Fe90Ni10) liquids alloyed with 3 and 5 wt % carbon undergo a polyamorphic liquid structure transition at approximately 5 GPa. Corroborating the experimental observations, our first‐principles molecular dynamic calculations reveal that the structural transitions result from the marked prevalence of three‐atom face‐sharing polyhedral connections in the liquids at >5 GPa. The structure and polyamorphic transitions of liquid iron‐nickel‐carbon alloys govern their physical and chemical properties and may thus cast fresh light on the chemical evolution of terrestrial planets and moons.

The inexhaustible mechanical kinetic energy can be extracted from wind and flowing water. Besides, flowing water also possesses electrostatic energy owing to the triboelectric charges caused by contacting with surrounding media, such as air. Here, a rotating hybridized triboelectric nanogenerator (TENG) has been established, by comprising of a water‐TENG (W‐TENG), a disk‐TENG (D‐TENG), and an electromagnetic generator (EMG), which has been explored for simultaneously harvesting energies from flowing water and wind. The W‐TENG is fabricated by wheel blades, polyvinylidene fluoride (PVDF), superhydrophobic polytetrafluoroethylene (PTFE), and aluminum to harvest the electrostatic energy. Moreover, the flowing water and wind impact on the wheel blades also causes the rotation motion of D‐TENG and EMG, resulting in being converted into electricity. At the rotation speed of 200 rpm, the short circuit current of D‐TENG and EMG can reach 0.4 μA and 7 mA, respectively. The open circuit voltage of W‐TENG can be up to 10 V at a flowing water rate of 60 ml s−1. Besides, the hybridized NG is demonstrated to harvest water and wind energy and to act as a power source to charge a lithium battery or capacitor, which can drive LEDs, PH monitoring system, and wireless temperature and humidity sensing system. All these results show the potentials of the hybridized NG for harvesting multiple types of energies from the environment and constructing different self‐powered systems.

Sleeping disorder is a major health threatening in high‐pace modern society. Characterizing sleep behavior with pressure‐sensitive, simple fabrication, and decent washability still remains a challenge and highly desired. Here, a pressure‐sensitive, large‐scale, and washable smart textile is reported based on triboelectric nanogenerator (TENG) array as bedsheet for real‐time and self‐powered sleep behavior monitoring. Fabricated by conductive fibers and elastomeric materials with a wave structure, the TENG units exhibit desirable features including high sensitivity, fast response time, durability, and water resistance, and are interconnected together, forming a pressure sensor array. Furthermore, highly integrated data acquisition, processing, and wireless transmission system is established and equipped with the sensor array to realize real‐time sleep behavior monitoring and sleep quality evaluation. Moreover, the smart textile can further serve as a self‐powered warning system in the case of an aged nonhospitalized patients falling down from the bed, which will immediately inform the medical staff. This work not only paves a new way for real‐time noninvasive sleep monitoring, but also presents a new perspective for the practical applications of remote clinical medical service.

Published: November 2017

An eco‐friendly biodegradable starch paper is introduced for use in next‐generation disposable organic electronics without the need for a planarizing layer. The starch papers are formed by starch gelatinization using a very small amount of 0.5 wt% polyvinyl alcohol (PVA), a polymer that bound to the starch, and 5 wt% of a crosslinker that bound to the PVA to improve mechanical properties. This process minimizes the additions of synthetic materials. The resultant starch paper provides a remarkable mechanical strength and stability under repeated movements. Robustness tests using various chemical solvents are conducted by immersing the starch paper for 6 h. Excellent nonpolar solvent stabilities are observed. They are important for the manufacture of organic electronics that use nonpolar solution processes. The applicability of the starch paper as a flexible substrate is tested by fabricating flexible organic transistors using pentacene, dinaphtho[2,3‐b:2′,3′‐f]thieno[3,2‐b]thiophene, and poly(dimethyl‐triarylamine) using both vacuum and solution processes. Electrically well‐behaved device performances are identified. Finally, the eco‐friendly biodegradability is verified by subjecting the starch paper to complete degradation by fungi in fishbowl water over 24 d. These developments illuminate new research areas in the field of biodegradable green electronics, enabling the development of extremely low‐cost electronics.

In this paper, by using the superabsorbent polymers (SAPs) from baby diaper, the 3D porous composites decorated with NiO and Ni nanoparticles (NNSCs) have been prepared via a facile dissolving‐freeze drying and subsequent annealing reactions. The porous carbon matrix (PCM) derived from the SAPs also provides a continuous highly conductive network to facilitate the fast charge transfer and form a stable solid electrolyte interface film. Furthermore, NNSC can exhibit the high specific capacity and excellent cycle performance as anode materials for lithium‐ion batteries. And more importantly, employing the PCM derived from baby diaper offers a green approach for other energy storage materials.

Anionic redox processes are vital to realize high capacity in lithium‐rich electrodes of lithium‐ion batteries. However, the activation mechanism of these processes remains ambiguous, hampering further implementation in new electrode design. This study demonstrates that the electrochemical activity of inert cubic‐Li2TiO3 is triggered by Fe3+ substitution, to afford considerable oxygen redox activity. Coupled with first principles calculations, it is found that electron holes tend to be selectively generated on oxygen ions bonded to Fe rather than Ti. Subsequently, a thermodynamic threshold is unravelled dictated by the relative values of the Coulomb and exchange interactions (U) and charge‐transfer energy (Δ) for the anionic redox electron‐transfer process, which is further verified by extension to inactive layered Li2TiS3, in which the sulfur redox process is activated by Co substitution to form Li1.2Ti0.6Co0.2S2. This work establishes general guidance for the design of high‐capacity electrodes utilizing anionic redox processes.

Published: November 2017

Herein, molybdenum disulfide (MoS2) and tungsten disulfide (WS2) quantum dots (QDs) are prepared by a facile and green technique, and characterized by microscopy and spectroscopy. The resulting products display exceptional stability in polyalkylene glycol (PAG) base oil, and are used for the first time as friction reducing and antiwear additives in PAG for steel/steel contact. Tribological measurements indicate that the stable dispersion consisting of PAG mixed with MoS2/WS2 QDs exhibits significant tribological properties compared with pure PAG and PAG containing MoS2/WS2 QDs nanosheets under different loads at elevated temperatures. The excellent tribological behaviors of MoS2/WS2 QDs are attributed to the formation of a boundary lubrication film, which can be generated not only by the physical entrapment of MoS2/WS2 QDs at the ball‐disk contact surfaces, but also by tribochemical reaction between MoS2/WS2 and the iron atoms/iron oxide species.

The use of dry transferred graphene as a templating layer to enhance face‐to‐face stacking in poly(3‐hexylthiophene) (P3HT) systems which is widely used for organic optoelectronics is investigated. In contrast to conventional poly(methyl methacrylate) (PMMA) assisted wet transferred graphene, dry transferred graphene is found in the current work to be quite suitable for use in the roll‐to‐roll process due to its lack of PMMA residue, whose removal would require high‐temperature annealing. Grazing‐incidence wide‐angle X‐ray scattering (GIWAXS) is used to determine the percentages of P3HT molecules adopting a face‐on orientation on the various substrates tested. When a P3HT film with a thickness of 30 nm is produced, the face‐on populations of P3HT are prominent on both the dry and wet transferred graphene layers. As the film thickness is increased to 50 nm, the face‐on population decreases on the wet transferred graphene surface, but retains high levels on the dry transferred graphene. GIWAXS, near‐edge X‐ray absorption fine structure, and atomic force microscopy data are combined to propose schematic models for the molecular stacking of P3HTs on the two differently transferred graphene surfaces.
