AbstractPlanar perovskite solar cells (PSCs) based on low‐temperature‐processed (LTP) SnO2 have demonstrated excellent photovoltaic properties duo to the high electron mobility, wide bandgap, and suitable band energy alignment of LTP SnO2. However, planar PSCs or mesoporous (mp) PSCs based on high‐temperature‐processed (HTP) SnO2 show much degraded performance. Here, a new strategy with fully HTP Mg‐doped quantum dot SnO2 as blocking layer (bl) and a quite thin SnO2 nanoparticle as mp layer are developed. The performances of both planar and mp PSCs has been greatly improved. The use of Mg‐SnO2 in planar PSCs yields a high‐stabilized power conversion efficiency (PCE) of close to 17%. The champion of mp cells exhibits hysteresis free and stable performance with a high‐stabilized PCE of 19.12%. The inclusion of thin mp SnO2 in PSCs not only plays a role of an energy bridge, facilitating electrons transfer from perovskite to SnO2 bl, but also enhances the contact area of SnO2 with perovskite absorber. Impedance analysis suggests that the thin mp layer is an “active scaffold” selectively collecting electrons from perovskite and can eliminate hysteresis and effectively suppress recombination. This is an inspiring advance toward high‐performance PSCs with HTP mp SnO2.

AbstractPlasma‐enhanced chemical vapor deposition (PECVD) is an applicable route to achieve low‐temperature growth of graphene, typically shaped like vertical nanowalls. However, for transparent electronic applications, the rich exposed edges and high specific surface area of vertical graphene (VG) nanowalls can enhance the carrier scattering and light absorption, resulting in high sheet resistance and low transmittance. Thus, the synthesis of laid‐down graphene (LG) is imperative. Here, a Faraday cage is designed to switch graphene growth in PECVD from the vertical to the horizontal direction by weakening ion bombardment and shielding electric field. Consequently, laid‐down graphene is synthesized on low‐softening‐point soda‐lime glass (6 cm × 10 cm) at ≈580 °C. This is hardly realized through the conventional PECVD or the thermal chemical vapor deposition methods with the necessity of high growth temperature (1000 °C–1600 °C). Laid‐down graphene glass has higher transparency, lower sheet resistance, and much improved macroscopic uniformity when compare to its vertical graphene counterpart and it performs better in transparent heating devices. This will inspire the next‐generation applications in low‐cost transparent electronics.

AbstractDeveloping low‐cost photovoltaic absorbers that can harvest the short‐wave infrared (SWIR) part of the solar spectrum, which remains unharnessed by current Si‐based and perovskite photovoltaic technologies, is a prerequisite for making high‐efficiency, low‐cost tandem solar cells. Here, infrared PbS colloidal quantum dot (CQD) solar cells employing a hybrid inorganic–organic ligand exchange process that results in an external quantum efficiency of 80% at 1.35 µm are reported, leading to a short‐circuit current density of 34 mA cm−2 and a power conversion efficiency (PCE) up to 7.9%, which is a current record for SWIR CQD solar cells. When this cell is placed at the back of an MAPbI3 perovskite film, it delivers an extra 3.3% PCE by harnessing light beyond 750 nm.

Published: January 2018

AbstractHighly efficient solution‐processable emitters, especially deep‐blue emitters, are greatly desired to develop low‐cost and low‐energy‐consumption organic light‐emitting diodes (OLEDs). A recently developed class of potentially metal‐free emitters, thermally activated delayed fluorescence (TADF) materials, are promising candidates, but solution‐processable TADF materials with efficient blue emissions are not well investigated. In this study, first the requirements for the design of efficient deep‐blue TADF materials are clarified, on the basis of which, adamantyl‐substituted TADF molecules are developed. The substitution not only endows high solubility and excellent thermal stability but also has a critical impact on the molecular orbitals, by pushing up the lowest unoccupied molecular orbital energy and triplet energy of the molecules. In the application to OLEDs, an external quantum efficiency (EQE) of 22.1% with blue emission having Commission Internationale de l'Eclairage (CIE) coordinates of (0.15, 0.19) is realized. A much deeper blue emission with CIE (0.15, 0.13) is also achieved, with an EQE of 11.2%. These efficiencies are the best yet among solution‐processed TADF OLEDs of CIE y < 0.20 and y < 0.15, as far as known. This work demonstrates the validity of adamantyl substitution and paves a pathway for straightforward realization of solution‐processable efficient deep‐blue TADF emitters.

AbstractWith the rapidly growing demand for low‐cost and safe energy storage, the advanced battery concepts have triggered strong interests beyond the state‐of‐the‐art Li‐ion batteries (LIBs). Herein, a novel hybrid Li/Na‐ion full battery (HLNIB) composed of the high‐energy and lithium‐free Na3V2(PO4)2O2F (NVPOF) cathode and commercial graphite anode mesophase carbon micro beads is for the first time designed. The assembled HLNIBs exhibit two high working voltage at about 4.05 and 3.69 V with a specific capacity of 112.7 mA h g−1. Its energy density can reach up to 328 W h kg−1 calculated from the total mass of both cathode and anode materials. Moreover, the HLNIBs show outstanding high‐rate capability, long‐term cycle life, and excellent low‐temperature performance. In addition, the reaction kinetics and Li/Na‐insertion/extraction mechanism into/out NVPOF is preliminarily investigated by the galvanostatic intermittent titration technique and ex situ X‐ray diffraction. This work provides a new and profound direction to develop advanced hybrid batteries.
Household production and consumption patterns of Teff in Ethiopia

Published: January 2018

AbstractTeff (Eragrostis tef) is a major staple grain of Ethiopia, where the crop was domesticated from 4000 to 1000 BC. The high food‐value Teff flour is basically used for preparing injera—a spongy pancake, the major component of the Ethiopian national dish. Due to its gluten‐free quality and high mineral content, the popularity of TeffTeff has been increasing in the western world. Very little is known, about the households that produce and consume Teff in Ethiopia. Using information from more than 9000 households collected by the World Bank and the Central Statistical Agency‐Ethiopia in 2011–2012 and 2013–2014, and applying econometric estimation approaches, this study reveals that Teff is mainly produced by uneducated, male‐headed rural households which have access to relatively more land and more family labor. In contrast, a higher proportion of Teff is consumed by urban households and those headed by an older, educated head. Based on the findings, this study asserts that the productivity of Teff should be enhanced by developing and disseminating high‐yielding varieties as Teff consumption has been increasing in general and, secondly, the resource‐poor Teff cultivators should be linked with the global value chain which may bring extra benefits to them in Ethiopia; however, the loss of domestic consumers’ surplus should also be considered economically.

Incorporation of mono and bimetallic MnNi into SAPO‐34 framework used in conversion of methanol to ethylene and propylene: Alteration of acidic properties and catalytic performance
Authors: Sadeghpour Parisa , Haghighi Mohammad 
Published: January 2018

AbstractNanostructured MeAPSO‐34 (Me═Mn, Ni, and MnNi) catalysts were synthesized by hydrothermal method using diethylamine (DEA) as template. The influence of Ni, Mn, and MnNi metal ions incorporation into the SAPO‐34 framework was investigated on its physicochemical properties and catalytic performance towards methanol to light olefins. The samples were characterized by X‐ray diffraction, field emission scanning electron microscopy, particle size distribution, energy dispersive X‐ray, Brunner–Emmett–Teller, Fourier transform infrared, UV–vis spectroscopy, and temperature‐programmed desorption of ammonia techniques. The results of X‐ray diffraction patterns revealed that various metals, based on their unique characteristics, play different roles in the crystallization of SAPO‐34 crystalline phase. The energy dispersive X‐ray micrographs indicated appropriate distribution of Mn metal ions in comparison with Ni modifier. The catalytic performance of these catalysts showed that the type of metal ions has low effect on methanol conversion, whereas it has considerable effect on stability and products selectivity. The stability of MnAPSO‐34 catalyst is much higher than the others. The selectivity of olefins for this sample with a high specific surface area and proper distribution of strong/weak acid sites was about 98% after 10 hr. The main steps of metal ions incorporation into the SAPO‐34 framework and a possible reaction mechanism for methanol to light olefins process were discussed in details.

AbstractA highly fluorescent (ΦF=0.60) and water‐soluble two‐dimensional (2D) honeycomb‐shaped supramolecular organic framework (SOF) was successfully synthesized in pure aqueous solution via self‐assembly of novel cyanostilbene‐functionalized trilateral guest molecules and cucurbit[8]uril hosts. The size of this fluorescent 2D SOF was >500 nm in diameter, 1.7 nm in thickness, and 3.9 nm in the honeycomb pore diameter. This 2D SOF holds potential as a new all‐organic photosensitizer template for photocatalytic H2 evolution from pure water.

Published: January 2018

Intolerance of uncertainty (IU) is a dispositional risk factor involving maladaptive responding under conditions of uncertainty. Recent data indicate that IU is likely elevated in youth with autism spectrum disorder (ASD) and is positively correlated with anxiety. This study examined whether IU may be associated with ASD independent of anxiety. Relationships between anxiety, ASD, and IU were examined in 57 children with ASD without co‐occurring intellectual disability and 32 control participants, ages 7–16 years. Hierarchal linear regressions were run to examine whether ASD variables, including emotion dysregulation, were predictive of IU when controlling for anxiety. Severity of social communication deficits, repetitive behaviors, and emotion dysregulation were each related to IU when controlling for the effects of anxiety. When these variables were entered into the regression model together, emotion dysregulation was the only significant predictor of IU. These findings suggest that IU is directly related to features of ASD possibly due to shared genetic, neurological, or psychological underpinnings. Autism Res 2018, 11: 636–644. © 2018 International Society for Autism Research, Wiley Periodicals, Inc.Lay SummaryYouth with ASD without co‐occurring intellectual disability experience high levels of intolerance of uncertainty (IU), which is related to anxiety. This study found that IU may also have a relationship with certain aspects of ASD, particularly emotion dysregulation.
A Measure of Delay Discounting Within the Academic Domain

Published: January 2018

AbstractIt is important to better understand the decision‐making processes involved in student procrastination, in order to develop interventions that reduce this common problem. Students may procrastinate because studying produces delayed reinforcers; however, no task measuring delay discounting of academic outcomes currently exists. In Experiment 1, we developed and piloted a measure of academic discounting modeled on titrating‐amount tasks successfully used in the discounting literature. Participants made hypothetical choices between working for money (the smaller, sooner reinforcer) and working on an assignment that was due at various times (the larger, later reinforcer). Participants showed systematic decreases in the subjective value of the assignment as a function of delay, and the hyperbolic and hyperboloid models described the shape of this decrease in value well. In general, larger delayed rewards are discounted less steeply than smaller delayed rewards (the magnitude effect). In Experiment 2, we observed the magnitude effect in academic discounting: Participants discounted a “not important” assignment more steeply than an “important” assignment. In the hyperboloid model, this change was captured by an increase in thesparameter. Results provide support for the validity of the academic discounting task. Copyright © 2018 John Wiley & Sons, Ltd.

BackgroundBainbridge‐Ropers syndrome (BRPS) is a recently identified severe disorder characterized by failure to thrive, facial dysmorphism, and severe developmental delay, caused by de novo dominant loss of function mutation in the ASXL3 gene.CaseWe report here the first case of prenatal BRPS in a fetus presenting with arthrogryposis on ultrasound and for pontocerebellar hypoplasia type 1 (PCH1) following neuropathological examination. The diagnosis was done by whole exome sequencing that identified a novel de novo ASXL3 mutation. We review 29 previous published cases.DiscussionThe fetopathological examination allowed to extend the phenotype to central nervous system and the genetic study highlights ASXL3 as a dominant gene responsible for PCH1 phenotype. Recognizing heterozygous ASXL3 mutation as a cause of prenatal PCH1 is essential for both large scale molecular analysis in the NGS era and genetic counseling.

AbstractA simple, selective and reliable LC‐MS/MS method was validated for simultaneous quantitation of darolutamide diastereomers in 50 μL mouse plasma using warfarin as an internal standard (IS) as per regulatory guidelines. Plasma samples were extracted by liquid–liquid extraction and the chromatographic separation was achieved on a Chiralpak IA column with an isocratic mobile phase 5 mm ammonium acetate–absolute alcohol (20:80, v/v) at a flow rate of 1.0 mL/min. Detection and quantitation was done in multiple reaction monitoring mode following the transitions m/z 397 → 202 and 307 → 250 for darolutamide diastereomers and the IS, respectively, in the negative ionization mode. The linearity range was 100–2400 ng/mL for each diastereomer. The intra‐ and inter‐day precisions were in the ranges of 1.78–4.20 and 4.34–14.6, and 3.63–4.74 and 4.78–5.15 for diastereomer‐1 and diastereomer‐2, respectively. Both diastereomers were found to be stable under different stability conditions. The validated method was applied to a pharmacokinetic study in mice. Following oral administration of darolutamide at 10 mg/kg, maximum concentration in plasma was 4189 and 726 ng/mL for diastereomer‐1 and diastereomer‐2, respectively. The terminal half‐life was found to be ~0.50 h for both the diastereomers. The AUC(0–t) was found to be 18,961 ng*h/mL for diastereomer‐1 and 1340 ng*h/mL diastereomer‐2.

Published: January 2018

Background and objectivesA metagenomic approach was applied to analyze endophytic bacterial diversity changes in Amaranthus cruentus L. subjected to mutagenesis‐based breeding.FindingsHigh‐throughput sequencing approach of 16S rRNA variability analysis was used for monitoring of the changes of endophytic bacterial diversity in selected M generations and varieties Ficha and Pribina of Amaranthus cruentus L. A total of 15,683,430 clusters were generated in the sequencing and 15,085,381 of them passed filter. Average cluster density was 646 clusters per mm2. A 95%, 97% of sequences were Q >30. All sequences were classified into the 44 orders that were identified from all the analyzed genotypes of Amaranthus. Metagenomic libraries of Ficha and Pribina showed the similar profiles of identified bacterial orders and that are different from the profiles of M1 and M7 generations after gamma radiance treatment.ConclusionsEndophytic bacteria diversity was higher in the starting variety and final new variety of Amaranthus when comparing to the M generations. Based on the laboratory conditions of the growth of analyzed plant material, it supposes that endophytic bacterial abundance differences are a result of temporary changes in the amount of bacterial endophytes and the metagenomic limitation of their identification.Significance and noveltyMetagenomic analysis provides a sensitive approach that facilitates the study of the endophytic bacteria changes in the leaves of plant after gamma radiation mutagenesis.

Published: January 2018

AbstractBackground and objectivesThe effectiveness of calcium and magnesium, as CaCl2 and MgCl2, respectively, to reduce acrylamide formation in tortilla chips fried in soybean oil during 30 s at 190°C was evaluated.FindingsAcrylamide was reduced 69%, 70%, and 74% by adding 0.04, 0.08, and 0.12 M of MgCl2 solutions to prepare the masa, compared with the reductions in 52%, 67%, and 52% obtained using 0.04, 0.08, and 0.12 M of CaCl2, respectively. The color, oil absorption, and the fracture force of tortilla chips using CaCl2 were similar to those of the control. In contrast, tortilla chips with added MgCl2 were darker and not as hard as the control.ConclusionsThe use of salts such as CaCl2 or MgCl2 is a reliable and effective acrylamide mitigation strategy in tortilla‐chip production.Significance and noveltyThe use of calcium or magnesium salts during masa preparation can be a simple, inexpensive, and effective way to mitigate acrylamide formation during the processing of tortilla chips and other thermally processed maize‐based foods that are widely consumed by the population.

Published: January 2018

AbstractBackground and objectivesRice quality can be primarily assessed by evaluating its texture after cooking. The classical sensory evaluation is an expensive and time‐consuming method as it requires training, capability, and availability of people. Therefore, this study investigated the possibility of replacing sensory evaluation by analyzing the relationship between sensory and instrumental texture and viscosity measurements.FindingsModels predicting the sensory evaluation were developed by applying statistical methods such as principal component analysis and polytomous logistic regression. The level of prediction efficiency of these models was obtained by estimating the apparent misclassification error rate and also using theROCcurve graph. The results indicated that the instrumental texture measurements were consistently related to sensory analysis. Similarly, viscosity measurements enabled the prediction of results obtained by sensory texture evaluation.ConclusionsPrincipal component analysis together with polytomous logistic regression is an efficient method to predict sensorial stickiness of rice using viscosity measures of texture as predictors.Significance and noveltyThe current study was able to correctly predict sensory stickiness in about 86% of cases using just one principal component formed by a combination of measures of apparent amylose content, gelatinization temperature, andRVAparameters.
