Published: September 2017

AbstractLiquid benzoquinone and naphthoquinone having diethylene glycol monomethyl ether groups are designed and synthesized as redox active materials that dissolve supporting electrolytes. The Li‐ion batteries based on the liquid quinones using LiBF4/PC show good performance in terms of voltage, capacity, energy efficiency, and cyclability in both static and flow modes. A battery is constructed without using intentionally added organic solvent, and its high energy density (264 W h L−1) demonstrates the potential of solvent‐free organic redox flow batteries using liquid active materials.

AbstractDramatic advances in perovskite solar cells (PSCs) and the blossoming of wearable electronics have triggered tremendous demands for flexible solar‐power sources. However, the fracturing of functional crystalline films and transmittance wastage from flexible substrates are critical challenges to approaching the high‐performance PSCs with flexural endurance. In this work, a nanocellular scaffold is introduced to architect a mechanics buffer layer and optics resonant cavity. The nanocellular scaffold releases mechanical stresses during flexural experiences and significantly improves the crystalline quality of the perovskite films. The nanocellular optics resonant cavity optimizes light harvesting and charge transportation of devices. More importantly, these flexible PSCs, which demonstrate excellent performance and mechanical stability, are practically fabricated in modules as a wearable solar‐power source. A power conversion efficiency of 12.32% for a flexible large‐scale device (polyethylene terephthalate substrate, indium tin oxide‐free, 1.01 cm2) is achieved. This ingenious flexible structure will enable a new approach for development of wearable electronics.

AbstractOne major challenge in engineering the magnetism of oxide heterostructures is controlling orbital reconstruction by tuning the charge transfer effect. This paper investigates the forward and backward charge transfer effect and the induced magnetic properties of BiFe1−xMnxO3/La2/3Ca1/3MnO3 heterostructures. Interfacial ferromagnetism is found to be qualitatively tunable by tuning the spatial distribution of interfacial electronic states. The subtle balance of magnetic coupling between FeOMn and MnOMn changed as the electronic structures are modified by charge transfer. The ions' valence is strongly correlated with the interfacial magnetic properties, extending the concept of the charge degrees of freedom affecting the magnetic coupling properties.

AbstractObjectivesThe objective of this study has been to confirm the sex and the affinity of an individual buried in a well‐furnished warrior grave (Bj 581) in the Viking Age town of Birka, Sweden. Previously, based on the material and historical records, the male sex has been associated with the gender of the warrior and such was the case with Bj 581. An earlier osteological classification of the individual as female was considered controversial in a historical and archaeological context. A genomic confirmation of the biological sex of the individual was considered necessary to solve the issue.Materials and methodsGenome‐wide sequence data was generated in order to confirm the biological sex, to support skeletal integrity, and to investigate the genetic relationship of the individual to ancient individuals as well as modern‐day groups. Additionally, a strontium isotope analysis was conducted to highlight the mobility of the individual.ResultsThe genomic results revealed the lack of a Y‐chromosome and thus a female biological sex, and the mtDNA analyses support a single‐individual origin of sampled elements. The genetic affinity is close to present‐day North Europeans, and within Sweden to the southern and south‐central region. Nevertheless, the Sr values are not conclusive as to whether she was of local or nonlocal origin.DiscussionThe identification of a female Viking warrior provides a unique insight into the Viking society, social constructions, and exceptions to the norm in the Viking time‐period. The results call for caution against generalizations regarding social orders in past societies.
Transition‐Metal‐Free Ring‐Opening Silylation of Indoles and Benzofurans with (Diphenyl‐tert‐butylsilyl)lithium

Published: September 2017

AbstractA practical method is presented for ring opening various indoles and benzofurans with concomitant stereoselective silylation using readily generated (diphenyl‐tert‐butylsilyl)lithium to afford ortho‐β‐silylvinylanilines or ‐phenols. Dearomatization of the heteroarene core proceeds in the absence of any transition‐metal catalyst through addition of a silyl anion and a subsequent stereoselective β‐elimination. DFT calculations provide insight into the mechanism. Functionalizing C−X bond cleavage of heteroarenes is rare and generally requires transition‐metal catalysts.
Vacancy‐Rich Monolayer BiO2−x as a Highly Efficient UV, Visible, and Near‐Infrared Responsive Photocatalyst
Authors: Li Jun , Wu Xiaoyong , Pan Wenfeng , Zhang Gaoke , Chen Hong 
Published: September 2017

AbstractVacancy‐rich layered materials with good electron‐transfer property are of great interest. Herein, a full‐spectrum responsive vacancy‐rich monolayer BiO2−x has been synthesized. The increased density of states at the conduction band (CB) minimum in the monolayer BiO2−x is responsible for the enhanced photon response and photo‐absorption, which were confirmed by UV/Vis‐NIR diffuse reflectance spectra (DRS) and photocurrent measurements. Compared to bulk BiO2−x, monolayer BiO2−x has exhibited enhanced photocatalytic performance for rhodamine B and phenol removal under UV, visible, and near‐infrared light (NIR) irradiation, which can be attributed to the vacancy VBi‐O′′′ as confirmed by the positron annihilation spectra. The presence of VBi‐O′′′ defects in monolayer BiO2−x promoted the separation of electrons and holes. This finding provides an atomic level understanding for developing highly efficient UV, visible, and NIR light responsive photocatalysts.

Published: September 2017

ABSTRACTNovel cationic waterborne polyurethanes (cWPU) were synthesized by step‐growth polymerization of hydroxyl telechelic natural rubber, molecular weight of 2800 g mol−1, toluene‐2,4‐diisocyanate, N‐methyl diethanolamine (NMDEA) as an emulsifier. The chemical structure of cWPU was confirmed by 1H‐nuclear magnetic resonance and Fourier transform infrared spectroscopy. The amounts of NMDEA and ethylene glycol under isocyanate (NCO) index of 100 on the properties of cWPU were studied. It was found that cWPU was stable under the concentration of NMDEA more than 1.50 mol and the particle sizes decreased with increasing of NMDEA content. Also, contact angle shows more hydrophilic materials by increasing of NMDEA. Extended cWPU was found in two ranges of nano size. Chain extender has strongly affected cWPU film formation, increasing of mechanical properties, and thermal properties. In addition, stress–strain curve and scanning electron microscopy image shows the change of behavior from soft elastic to ductile plastic by adding ethylene glycol. © 2017 Wiley Periodicals, Inc. J.

Published: September 2017

AbstractWe successfully fabricate a well‐defined inorganic/organic hybrid Cu2O@Cu/Co‐ZIF (ZIF=zeolitic imidazolate frameworks) by use of growth of dual‐metal Cu/Co‐ZIF on the obtained Cu2O hollow spheres. The key point of the strategy is coupling the in situ self‐sacrificing template. Cu2O and the coordination of metal ions (Cu+ and Co2+) with 2‐methylimidazole. This new hybrid was characterized by powder X‐ray diffraction, (scanning) transmission electron microscopy, energy‐dispersive spectroscopy mapping, in situ FT‐IR spectroscopy, UV/Vis diffuse reflection spectroscopy, N2 sorption measurements, and electron spin resonance. It was evidenced that Cu/Co‐ZIF nanocrystals have been assembled to continuous shells surrounding the Cu2O cores as well as in the voids between layers and inner pores. Cu2O@Cu/Co‐ZIF exhibits visible light responsiveness and holds potential as narrow band gap semiconductor and visible photocatalyst.
How Incidental Confidence Influences Self‐Interested Behaviors: A Double‐Edged Sword
Authors: Tsai Claire I. , Xie Jia Lin 
Published: September 2017

AbstractThe present research investigates how incidental confidence influences self‐interested behaviors. It is well established that being in a psychological state of lower confidence causes people to experience psychological aversion that they are motivated to reduce. We study the transfer effect of confidence; people strive to compensate for lower confidence in one domain by obtaining higher status in other unrelated domains. Prior research has linked money with status and suggested that money can increase confidence. Building on this research, we proposed and showed in four experiments that lower incidental confidence increased self‐interested behaviors that brought financial gains. Drawing on research on competitive altruism, we also predicted and found that when altruism, rather than money, was seen as the primary source of status, the effect of incidental confidence reversed such that lower incidental confidence decreased self‐interested behaviors. Data ruled out alternative explanations and provided consistent evidence for the proposed compensatory mechanism. We also discussed theoretical and practical implications of the present research.

Divergent anomaly in mesocorticolimbic dopaminergic circuits might be associated with different depressive behaviors, an animal study
Authors: Bai Mei , Zhu Xiongzhao , Zhang Li , Zhang Yi , Xue Liang , Wang Yuting , Zhong Mingtian , Zhang Xiuwu 
Published: September 2017

AbstractBackgroundThe mesocorticolimbic dopamine system, which originates from the ventral tegmental area (VTA) and projects primarily to the prefrontal cortex (PFC), olfactory tubercle (OT), nucleus accumbens (NAc), dorsal striatum (ST), and the amygdala (AMy), plays a pivotal role in determining individual motivation and sensitivity to rewards, namely, anhedonia. Not all depressive individuals exhibited anhedonia, thus, it is natural to speculate that the heterogenous manifestations of depression might be related to the mesocorticolimbic dopamine system. Maternal deprivation (MD) and chronic unpredictable stress (CUPS) are two well‐established depressogenic stressors, and they were proven to induce different depressive phenotypes.MethodsThe depressive and anxiety‐like behaviors of MD and CUPS‐treated rats were measured by classical behavioral tests including open field, forced swimming, and sucrose preference test. The expression of D1‐5 dopamine receptors and DAT mRNA and protein in the mesocorticolimbic dopamine system of rats exposed to MD and CUPS were measured by real‐time PCR and Western blot, respectively.ResultsSevere anhedonia was observed in MD but not CUPS rats. Divergent expression of D1 and D2 receptors and DAT mRNA and protein in the mesocorticolimbic dopamine system were found between MD and CUPS rats. Significant correlations between different depressive behaviors and D1‐/D2‐like receptors and DAT protein levels in the mesocorticolimbic dopamine system were observed.ConclusionDifferent depressive behaviors of rats such as anhedonia, passive coping behavior, and declined exploratory interest might be related to divergent dopaminergic pathways. Anhedonia is associated with the dysfunction of VTA‐NAc and VTA‐OT dopaminergic pathways, the passive coping behavior is related to the dysregulation of VTA‐PFC and VTA‐AMy pathways, and individual exploratory interest is associated with abnormal activity of VTA‐PFC and VTA‐ST pathways.

Published: September 2017

AbstractIntroductionInsufficient literature exists regarding the clinimetric properties of the Upright Motor Control Test Knee Extension and Flexion subtests (UMCT‐KE and UMCT‐KF, respectively). This study examined the interrater and test‐retest reliability of these subtests, and determined the relationship between the UMCT‐KE and a clinical measure of muscle function in a sample of adults with chronic stroke.MethodsThree raters independently administered the UMCT‐KE and UMCT‐KF on adults with chronic stroke with spasticity/abnormal movement patterns. Testing of each participant occurred on two occasions (T1 and T2) separated by a two‐week interval. A fourth rater independently administered the Five Times Sit to Stand Test (FTSST), a measure of lower extremity muscle function (power), on T2.ResultsTwenty‐nine adults aged 55 ± 8 years, comprising 21 men (72%), and who were 9 ± 5 years poststroke, completed the study. Most of the participants (66%, 19/29) did not require an assistive device during walking. The UMCT‐KE and UMCT‐KF demonstrated substantial interrater reliability (W = 0.63–0.67 and 0.72–0.75, respectively) and substantial to almost perfect test‐retest reliability across the raters (W = 0.75–0.82 and 0.85–0.87, respectively). The UMCT‐KE showed positive inverse correlation with the FTSST (ρ = −0.52, p = .003).ConclusionsScores on both subtests are reproducible within raters and across different raters. The relationship of UMCT‐KE scores with FTSST scores implies that the UMCT‐KE can provide information that relates with the construct of muscle function in a weight‐bearing position.

AbstractSynthetic antibody libraries have been used to generate antibodies with favorable biophysical and pharmacological properties. Here, we describe the design, construction, and validation of a phage‐displayed antigen‐binding fragment (Fab) library built on a modified trastuzumab framework with four fixed and two diversified complementarity‐determining regions (CDRs). CDRs L1, L2, H1, and H2 were fixed to preserve the most commonly observed “canonical” CDR conformation preferred by the modified trastuzumab Fab framework. The library diversity was engineered within CDRs L3 and H3 by use of custom‐designed trinucleotide phosphoramidite mixes and biased towards human antibody CDR sequences. The library contained ≈7.6 billion unique Fabs, and >95 % of the library correctly encoded both diversified CDR sequences. We used this library to conduct selections against the human epidermal growth factor receptor‐3 extracellular domain (HER3‐ECD) and compared the CDR diversity of the naïve library and the anti‐HER3 selection pool by use of next‐generation sequencing. The most commonly observed CDR combination isolated, named Her3‐3, was overexpressed and purified in Fab and immunoglobulin G (IgG) formats. Fab HER3‐3 bound to HER3‐ECD with a KD value of 2.14 nm and recognized cell‐surface HER3. Although HER3‐3 IgG bound to cell‐surface HER3, it did not inhibit the proliferation of HER3‐positive cells. Near‐infrared imaging showed that Fab HER3‐3 selectively accumulated in a murine HER3‐postive xenograft, thus providing a lead for the development of HER3 imaging probes.

AbstractA new approach to the synthesis of fused 1,2,3‐thiaselenazoles—rare five‐membered heterocycles that contain two different chalcogens—from the corresponding 1,2,3‐dithiazoles and SeO2was accomplished by selective exchange of S and Se atoms. The fused carbo‐ and heterocyclic units were indene, naphthalenone, cyclohexadienone, cyclopentadiene, benzoannulene, and benzoxazine. The molecular structures of two of the thiaselenadiazole products and one of the dithiazole precursors were confirmed by single‐crystal X‐ray diffraction. The reaction is highly solvent selective; it only takes place in solvents that contain a C=O group (e.g., DMF or tetramethylurea). According to DFT calculations, the reaction is thermodynamically favorable. Based on the DFT calculations and77Se NMR spectroscopy, two tentative mechanisms that feature isomeric transition states and intermediates are suggested for the reaction via ring‐opening addition of SeO2to the S−X dithiazole bond (X=N or S). The DFT‐calculated first adiabatic electron affinities of the compounds were chalcogen independent and positive in all cases, which assumes formation of thermodynamically stable radical anions (RAs). These calculated RAs featured either normal or abnormal elongation of the S1−X2 (X=S or Se) bond relative to their neutral precursors and possessed π* or σ* SOMOs, respectively.

AbstractWe report the inclusion of carboxy‐ and amine‐substituted molecular nanodiamonds (NDs) adamantane, diamantane, and triamantane by β‐cyclodextrin and γ‐cyclodextrin (β‐CD and γ‐CD), which have particularly well‐suited hydrophobicity and symmetry for an optimal fit of the host and guest molecules. We studied the host–guest interactions in detail and generally observed 1:1 association of the NDs with the larger γ‐CD cavity, but observed 1:2 association for the largest ND in the series (triamantane) with β‐CD. We found higher binding affinities for carboxy‐substituted NDs than for amine‐substituted NDs. Additionally, cyclodextrin vesicles (CDVs) were decorated with d‐mannose by using adamantane, diamantane, and triamantane as non‐covalent anchors, and the resulting vesicles were compared with the lectin concanavalin A in agglutination experiments. Agglutination was directly correlated to the host–guest association: adamantane showed lower agglutination than di‐ or triamantane with β‐CDV and almost no agglutination with γ‐CDV, whereas high agglutination was observed for di‐ and triamantane with γ‐CDV.
