Published: November 2020

AbstractOver the past decade, lithium‐ion batteries (LIBs) have been widely applied in consumer electronics and electric vehicles. Polymer electrolytes (PEs) play an essential role in LIBs and have attracted great interest for the development of next‐generation rechargeable batteries with high energy density. Due to the several practical applications of LIBs and high demands for LIBs performance, many state‐of‐the‐art PEs with different structures and functionalities have been developed to regulate the LIBs performance, especially their rate capability, cycling durability, and lifespan. In this review, the recent advances in high‐performance LIBs prepared using well‐defined PEs are summarized. The ion‐transport mechanisms and preparation techniques of various well‐defined PE classes compared to conventional PEs are also discussed. The aim is to elucidate the structure code for advanced PEs with optimized properties, including ionic conductivity, mechanical properties, processability, accessibility, etc. The existing challenges and future perspectives are also discussed, setting the basis for designing novel PEs for energy conversion applications.

AbstractThe ability to control the degree of spin in molecular junctions (MJs) is attractive for their applications in spintronics. Here, it is demonstrated that spin‐resolved quantum interference (SQI) can effectively improve spin‐filtering behavior of MJs. By first‐principle calculations in combination with nonequilibrium Green's function investigations, spin‐resolved charge transport in graphene/Cr‐porphyrin/graphene MJs shows that, due to the SQI, the tunable spin filtering behaviors can be achieved by changing the length of molecule. The SQI related phase coherence/decoherence in these MJs is revealed by considering the effects of temperature and electron–phonon interactions. Furthermore, a higher spin filtering efficiency in low bias region can be obtained by Cr‐doped in single‐porphyrin junction, due to the Cr‐enhanced SQI. These results show great potential for the application of MJs with SQI in the molecular intergrated circuit and provide a promising way for designing spin molecular devices by using quantum interference.

AbstractThe use of plant growth–promoting rhizobacteria (PGPR) associated with rhizobia may improve biological N fixation, nutrient acquisition, and grain yield of the peanut (Arachis hypogaea L.). However, few studies have reported the effect of inoculation of rhizobia and PGPR in association with Mo in tropical soil conditions. This study examined the effectiveness of (co)inoculation with Bradyrhizobium spp. and/or Azospirillum brasilense and Mo application in improving the yield response of creeping peanut crop (‘RUNNER IAC 886’). The effects of rhizobacteria and Mo on nodulation, crop growth, chlorophyll content, and yield of peanut were investigated in a moderately acidic sandy soil (pH 5.0) from the Brazilian Cerrado during the 2016–2017 and 2017–2018 growing seasons. Four seed inoculation treatments (control [uninoculated seeds], inoculation with Bradyrhizobium spp. strains SEMIA 5079 and SEMIA 5080, inoculation with Azospirillum brasilense strains Ab‐V5 and Ab‐V6, and co‐inoculation of Bradyrhizobium spp. and Azospirillum brasilense) and two Mo levels (0 and 200 mg Mo kg−1 of seed) were studied. Results showed that the effects of the interaction between rhizobacteria and Mo application were not significant (p > .05) for all crop traits. Root nodulation, dry matter accumulation, and chlorophyll content were significantly greater in Mo‐treated peanut plants than control plants in both seasons. However, the response of crop grain yield was significantly greater (17.7%) in Mo‐treated plants only in the 2017–2018 season. Therefore, the improved root nodulation, crop growth, and chlorophyll content resulting from Mo application can lead to increased pod and grain yield in peanut. Inoculation with Bradyrhizobium spp. alone or combined with A. brasilense enhanced root nodulation, chlorophyll content, and peanut grain yield. Over two harvests, average peanut grain yield increased by 25.3 and 24.0% with inoculation of Bradyrhizobium spp. alone and combined with A. brasilense, respectively, compared with noninoculated plants. Due to lower cost and higher profitability, inoculation of Bradyrhizobium spp. alone is the most efficient practice for peanut cropping in sandy soils of the Brazilian Cerrado. Together with Mo application, these agricultural practices can be recommended for Brazilian peanut farmers.

AbstractBased upon precise terahertz (THz) measurements of the solvated amino acid glycine and accompanying ab‐initio molecular‐dynamics simulations, we show that the N‐C‐C‐O open/close mode at 315 cm−1 serves as a sensitive, label‐free probe for the local protonation of the amide group. Experimentally, we can show that this holds not only for glycine but also for diglycine and valine. The approach is more general, since the changes due to protonation result in intensity changes which can be probed by THz time domain (0–50 cm−1) as well as by precise THz‐FT spectroscopy (50–400 cm−1). A detailed analysis allows us to directly correlate the titration spectra with pKa values. This demonstrates the potential of THz spectroscopy to probe the charge state of a natural amino acid in water in a label‐free manner.

Published: November 2020

AbstractThe orchestration of ever larger conformational changes is made possible by the development of increasingly complex foldamers. Aromatic sheets, a rare motif in synthetic foldamer structures, have been designed so as to form discrete stacks of intercalated aromatic strands through the self‐assembly of two identical subunits. Ion‐mobility ESI‐MS confirms the formation of compact dimers. X‐ray crystallography reveals the existence of two distinct conformational dimeric states that require large changes to interconvert. Molecular dynamics simulation validates the stability of the two conformations and the possibility of their interconversion.

Published: November 2020

AbstractThe strain change of double network (DN) hydrogels during compressive mechanical and frictional tests is crucial for their performances. The positive effect of the sacrificed network for prohibiting crack in DN hydrogel is likely to be initiated by large strain. In this study, the mechanical and tribological properties of polyvinyl alcohol/polyacrylamide (PVA/PAAm) DN hydrogels are investigated from the viewpoint of strain. The compressive tangent modulus of PVA/PAAm DN hydrogel with 15 wt% AAm shows a sudden increase in the strain of 60% due to the sacrificed PAAm network. The optimized friction behavior is obtained from PVA/PAAm hydrogel with 5 wt% of AAm content, which is not consistent with the optimal compressive modulus at 15 wt% of AAm content. The variation of frictional coefficient of PVA/PAAm DN hydrogels with load is quite different for migrating and stationary contact configurations. The biphasic lubrication mechanism transited to solid–solid contact dominant mechanism is also induced by the high strain at heavy load.
Bone regeneration via skeletal cell lineage plasticity: All hands mobilized for emergencies
Authors: Matsushita Yuki , Ono Wanida , Ono Noriaki 
Published: November 2020

AbstractAn emerging concept is that quiescent mature skeletal cells provide an important cellular source for bone regeneration. It has long been considered that a small number of resident skeletal stem cells are solely responsible for the remarkable regenerative capacity of adult bones. However, recent in vivo lineage‐tracing studies suggest that all stages of skeletal lineage cells, including dormant pre‐adipocyte‐like stromal cells in the marrow, osteoblast precursor cells on the bone surface and other stem and progenitor cells, are concomitantly recruited to the injury site and collectively participate in regeneration of the damaged skeletal structure. Lineage plasticity appears to play an important role in this process, by which mature skeletal cells can transform their identities into skeletal stem cell‐like cells in response to injury. These highly malleable, long‐living mature skeletal cells, readily available throughout postnatal life, might represent an ideal cellular resource that can be exploited for regenerative medicine.
The impact of expertise on hedonic escalation: A moderating role of regulatory focus

Published: November 2020

AbstractThis research conducted two experiments to examine the effects of expertise and the regulatory focus on hedonic escalation when consuming various products within a brand. Study 1 showed that expertise results in different levels of hedonic escalation. Novice consumers experienced higher hedonic escalation than expert consumers did, considering their knowledge of products. Study 2 verified the moderating role of regulatory focus on the relationship between expertise and hedonic escalation. It revealed that promotion‐focused experts exhibited greater hedonic escalation, buying various products in a brand than prevention‐focused experts did. Conversely, promotion‐focused novices showed lower hedonic escalation, buying products in a brand than prevention‐focused novices did.

Published: November 2020

AbstractIn this study, a strategy that can result in the polyaniline (PANI) solely confined within the nanopores of a metal–organic framework (MOF) without forming obvious bulk PANI between MOF crystals is developed. A water‐stable zirconium‐based MOF, UiO‐66‐NH2, is selected as the MOF material. The polymerization of aniline is initiated in the acidic suspension of UiO‐66‐NH2 nanocrystals in the presence of excess poly(sodium 4‐styrenesulfonate) (PSS). Since the pore size of UiO‐66‐NH2 is too small to enable the insertion of the bulky PSS, the quick formation of pore‐confined solid PANI and the slower formation of well dispersed PANI:PSS occur within the MOF crystals and in the bulk solution, respectively. By taking advantage of the resulting homogeneous PANI:PSS polymer solution, the bulk PANI:PSS can be removed from the PANI/UiO‐66‐NH2 solid by successive washing the sample with fresh acidic solutions through centrifugation. As this is the first time reporting the PANI solely confined in the pores of a MOF, as a demonstration, the obtained PANI/UiO‐66‐NH2 composite material is applied as the electrode material for supercapacitors. The PANI/UiO‐66‐NH2 thin films exhibit a pseudocapacitive electrochemical characteristic, and their resulting electrochemical activity and charge‐storage capacities are remarkably higher than those of the bulk PANI thin films.

Authors: Okoye Onyedikachi Kingsley , Li Huan , Gong Zheng 
Published: November 2020

AbstractWetland environment and habitat loss increase the rate of biodiversity decline and affect our ecosystems. Yancheng National Nature Reserve (YNNR) is a protected area dedicated to endangered migratory bird species to overwinter. However, it currently has a record low influx of migrating birds and might therefore be losing its founding purpose. We used remote sensing technology to assess and quantify the impacts and effects of invasive halophytesSpartina alterniflorain the habitat loss and shrinkage of endangered bird wintering habitat from 2003 to 2018. We also attempted to ascertain the causes and triggers of avian population decline and its relationship with habitat loss, as these phenomena threaten and endanger species both locally and globally. Our study shows how YNNR has lost about 80% of migratory bird habitat to invasiveS. alternifloraandPhragmites australis, a native halophyte plant in the reserve. Furthermore, shoreline erosion triggered the retraction ofS. alternifloraand its backward growth towardSuaeda Salsa, the preferred foraging habitat for migratory birds in the zone, which is a possible cause of their decline.

AbstractThe main objective of current study was to evaluate the antioxidant potential and nutritional composition of milk thistle with special reference to silymarin. For the purpose, different varieties of milk thistle were procured from three different cities of Pakistan. The study was comprised of three different phases. In 1st phase, nutritional composition, that is, moisture, fat, protein, fiber, and nitrogen free extract, was determined according to their respective methods. Moreover, antioxidant potential and quantification of silymarin content were explored in 2nd phase. Furthermore, in last phase, milk thistle seeds tea was developed and evaluated for nutritional and sensorial characteristics. At last, data obtained from each parameter was subjected to appropriate statistical design to determine the level of significance. Results showed significant difference in the nutritional and chemical composition of different milk thistle varieties as well as locations. Moreover, moisture content, ash content, fat content, fiber content, protein content, and NFE varied from 6.27% to 5.01%, 2.37 to 1.25%, 23.19 to 19.74%, 7.4 to 4.39%, 30.09 to 20.74%, and 45.42 to 34.13%, respectively. Furthermore, silymarin content quantified though HPLC ranged from 1669.5 mg/g to 1607.6 mg/g for soxhlet extract whereas, 1,840.6 mg/g to 1765.9 mg/g for microwave‐assisted extraction extract. Conclusively, it was depicted from the results that in case of variety, Blue was the best than White whereas, Islamabad was best in case of location.

Published: November 2020

AbstractAcute myeloid leukaemia (AML) is a blood cancer where undifferentiated myeloid cells are increased in the bone marrow and peripheral blood. As AML is dangerous and shows poor prognosis, many researchers categorised the relevant cytogenetic factors according to risk and prognosis. However, the specific reasons for poor cytogenetic factors remain unknown. We analysed a large data set from AML patients and found that TPD52 expression is elevated in patient groups with poor cytogenetic factors. As the amino acid sequence of TPD52 is evolutionally conserved in vertebrates, zebrafish embryos were used to investigate the function of TPD52. Since myeloid‐biased haematopoietic stem cells (HSCs) are relevant to AML, the function of TPD52 in the development of HSCs was investigated. We determined that the zebrafish paralog, tpd52, is important for the maintenance of HSCs through regulation of cell proliferation. As tpd52 is linked to cell proliferation in zebrafish embryos, the proliferation‐related gene, CD59, was correlated to TPD52 in every AML cohort with a high correlation coefficient. We suggest that TPD52 can be a novel therapeutic target for AML patients with poor cytogenetic factors. Additionally, more studies between TPD52 and CD59 will further increase the value of TPD52 as a novel target.

Published: November 2020

AbstractPancreatitis, panniculitis, and polyarthritis (PPP) syndrome is a rare triad of hyperlipasemia, erythematous cutaneous nodules, and oligo‐ or mono‐arthritis and a rare complication of pancreatic diseases. The treatment for PPP syndrome complicated by untreatable pancreatic diseases can be challenging because the causal treatment may not be available. Herein, I report a case of a 72‐year‐old man presenting with PPP syndrome, complicated by untreatable terminal pancreatic adenocarcinoma, who was successfully managed with intra‐articular knee aspiration, intra‐articular injection of lidocaine and corticosteroid, and decompression of panniculitis.

AbstractBackground and AimIn the present coronavirus disease‐19 (COVID‐19) era, health‐care workers (HCWs) warrant special attention because of their higher risk and potential to transmit the disease. Gastroenterology services include emergency and critical care along with the endoscopy procedures, which have aerosol‐generating potential. This study was aimed at auditing the COVID‐19 impact on HCWs working in the Gastroenterology department of our hospital.MethodsThe COVID‐19 status of 117 HCWs was collected using either polymerase chain reaction (PCR) or Immunoglobulin G (IgG) seroassay. COVID‐19 positivity was correlated with demographic characteristics, job profile, area of work, and medical history.ResultsThirty‐eight HCWs (32.48%) showed evidence of COVID‐19 using PCR (23.93%) or only IgG assay (8.55%). Endoscopy technicians (68.75%) exhibited significantly higher (P = 0.003) COVID‐19 incidence compared to doctors (20.69%). Those working in the critical care units exhibited a trend toward higher COVID‐19 incidence (42.86%). None of the six HCWs who received adequate hydroxychloroquine prophylaxis developed evidence of COVID‐19. All the HCWs with COVID‐19 disease recovered. However, there was a considerable loss of “man‐days.”ConclusionsIn our setting, we observed a high COVID‐19 risk for HCWs working in the Gastroenterology department, with the highest risk among the endoscopy technicians. A more stringent triaging and pretesting of patients, as well as HCWs, might decrease the risk of COVID‐19. Further multicenter studies are needed to evaluate the risk and related parameters.
Modulation of seasonal precipitation in Argentina by the South Pacific high
Authors: Garbarini Eugenia María , González Marcela Hebe , Rolla Alfredo Luis 
Published: November 2020

AbstractThe aim of this work is to quantify the influence of the position and intensity of the South Pacific High (SPH) over seasonal rainfall in Argentina. Some indices were defined to measure the position and intensity of the SPH, and they were correlated with seasonal precipitation to study the relationship between them. Results indicate that the intensity of the SPH affects precipitation mainly in northern Argentina during spring and in the southern region in autumn and winter. The latitudinal shift of the SPH has proved to have a relevant impact on precipitation in the northeast in summer and winter, and in some regions of southern and central Argentina during winter and spring. When studying the possibility to foresee precipitation behaviour with a one‐month lag, these metrics were not able to predict precipitation effectively in the northwest. On the contrary, the SPH intensity showed significant lagged correlations with rainfall mainly in the northeast, central‐east and south during spring and summer while the position of the SPH is mostly significantly correlated with summer and winter precipitation in the northeast and central Argentina. Results suggest that the situation of SPH can provide some rainfall predictability.
