AbstractA light‐inspired hydroxyapatite (Hap)/nitrogen‐doped carbon dots (NCDs) modified graphene oxide (GO) heterojunction film is developed, which shows a promoted separation of interfacial electrons and holes and an inhibited recombination efficiency via hole depletion. The metabolism of bacteria on this film is significantly inhibited under light irradiation, due to the enhanced photocatalytic and photothermal effects. In addition, the electron transfer from the plasmonic membrane to the GO/NCD/Hap film further inhibits the adenosine triphosphate process of bacteria, thus leading to the synergetic antibacterial efficacy. Meanwhile, the electron transfer between film and cell membrane induces the Ca2+ flow after irradiation, which can promote the migration and proliferation of cells and alkaline phosphatase enhancement, thus favoring the tissue reconstruction. An in vivo test discloses that the vascular injury repair is achieved through the Ca2+‐activated PLCγ1/ERK pathway, identified by the enhanced CD31 expression. Moreover, the increased CD4+/CD8+ lymphocytes are ameliorative by activating the PI3K/P‐AKT pathway. Consequently, the electron transfer boosts the synergic photodynamic and photothermal therapeutic effects for bacterial infection by Ca2+ flow for immunotherapy. This mild phototherapy approach with GO/NCDs/Hap, which can simultaneously repair injured vessels and relieve inflammation reactions, will increase the clinical application of noninvasive phototherapy in the near future.

Published: July 2020

AbstractPolyethylene terephthalate (PET) is selectively depolymerized by a carbon‐supported single‐site molybdenum‐dioxo catalyst to terephthalic acid (PTA) and ethylene. The solventless reactions are most efficient under 1 atmosphere of H2. The catalyst exhibits high stability and can be recycled multiple times without loss of activity. Waste beverage bottle PET or a PET + polypropylene (PP) mixture (simulating the bottle + cap) proceeds at 260 °C with complete PET deconstruction and quantitative PTA isolation. Mechanistic studies with a model diester, 1,2‐ethanediol dibenzoate, suggest the reaction proceeds by initial retro‐hydroalkoxylation/β‐C−O scission and subsequent hydrogenolysis of the vinyl benzoate intermediate.

AbstractOxidative anion insertion into graphite in an aqueous environment represents a significant challenge in the construction of aqueous dual‐ion batteries. In dilute aqueous electrolytes, the oxygen evolution reaction (OER) dominates the anodic current before anions can be inserted into the graphite gallery. Herein, we report that the reversible insertion of Mg‐Cl superhalides in graphite delivers a record‐high reversible capacity of 150 mAh g−1 from an aqueous deep eutectic solvent comprising magnesium chloride and choline chloride. The insertion of Mg‐Cl superhalides in graphite does not form staged graphite intercalation compounds; instead, the insertion of Mg‐Cl superhalides makes the graphite partially turbostratic.

Authors: Shibata Yuki , Kurokawa Takayuki , Aizawa Tomoyasu , Gong Jian Ping 
Published: July 2020

AbstractThis study investigated whether hydrogels comprising hydrophilic cationic polymers have similar bactericidal effects. Bacteria were seeded on hydrogels and agar and their viability was assessed with time. Cationic hydrogels displayed bactericidal effects upon long‐term bacterial contact. Furthermore, we assessed the areal density of cationic monomer unit of the cationic hydrogels, water content, and the initial elastic modulus. We examined correlations between each factor and bacterial death ratios; consequently, the bacterial death ratios were strongly correlated with the areal density of cationic hydrogel monomers. Elastic energy (Wel) generated at the cytomembrane ion‐binding region and the cationic hydrogel and the cytomembrane interfacial energy (Wf) were estimated; consequently, Wel exceeded Wf at higher contact areas. The cationic hydrogel may extract cytomembranes with a reasonable adsorption area. Therefore, cationic hydrogels may be used as probes for ultrasonic echo to sterilize medical equipment.

Published: July 2020

AbstractSilicon‐containing arylacetylene resins (PSAs) can be used in high temperature environment due to their excellent thermal stability. However, their high temperature oxidation is still bottle‐neck for further application. Herein, Materials Genome Initiative (MGI) was utilized to identify a target monomer, 3,6‐diethynylcarbazole (DEC), to design new PSAs with enhanced antioxidant properties and heat resistance. After incorporation of DEC, the thermal curing behavior observed using differential scanning calorimetry (DSC), fourier transform infrared (FTIR) and thermogravimetric analysis (TGA) revealed that obtained silicon‐containing carbazolylacetylene resins (PSA‐VBC) can exhibit hydroamination reaction to decrease the initial curing temperature. And the temperature at 5% weight loss (Td5) occurred in cured copolymers ranged from 665°C to 691°C, which showed excellent heat resistance. Moreover, the oxidation behavior of cured resins was investigated by thermogravimetric/derivative thermogravimetry (TG/DTG), X‐ray photoelectron spectroscopy (XPS) and scanning electron microscope (SEM). Upon the incorporation of DEC, the thermal oxidation decomposition temperature of PSA‐VBC were 100°C higher than those observed for PSAs, which also proved by XPS analysis results that the oxygen content of PSA‐VBC solidified oxide was lower than that of PSAs. In addition, the surface morphology of cured PSA‐VBC resins still maintained integrity after oxidation at 400°C for 2 hr, which showed excellent oxidation resistance.

Published: July 2020

AbstractTo explore the dependence of the microstructure and properties of thermoplastic vulcanizates (TPVs) on the molding process. The polypropylene/bromo‐isobutylene‐isoprene rubber thermoplastic vulcanizates (PP/BIIR‐TPVs) are molded by high rate shear injection and compression molding, and the phase morphology and physical‐mechanical properties of PP/BIIR‐TPVs specimens are investigated. Detailed small‐angle X‐ray scattering, scanning electron microscopy and atomic force microscopy investigations demonstrate that the high rate shear of injection molding not only decreases the size of BIIR particles but also induces the orientation of the PP matrix and further increases its crystallinity. Subsequently, the PP/BIIR‐TPVs molded by injection molding have higher tensile strength and Young's modulus, while the compression molding benefits to higher elongation at break. The mechanism regarding the effects of high rate shear during injection molding on phase morphology development of PP/BIIR‐TPVs is discussed. This study guides the preparation of TPVs products with desired properties.

Published: July 2020

AbstractLight‐sensitive drug delivery systems are considered ideal for applications in the biomedical fields for their ability to release the payload in an on‐demand spatiotemporal controlled manner through the manipulation of the light source. Among the broad radiation spectrum, near infrared (NIR) light is considered advantageous compared to UV and visible light, due to its inherently lower photodamage to normal tissues and deeper penetration to lesion areas. In this study, we report a successful synthesis of a polymer capable of undergoing partial degradation upon irradiation with NIR light by conjugating 10‐N‐carbamoyl linkage methylene blue (MB) moiety, a NIR photocleavable ligand, with polyethylene glycol (PEG). Through effective coupling of MB, a hydrophobic moiety, to the hydrophilic PEG molecule, an amphiphilic polymer was synthesized, as demonstrated by a lowered surface tension (55 mN/m at 0.1% wt/vol). Subsequently, photo‐induced reversal of surface activity associated with self‐assembled structure disruption, was displayed by surface tension measurements, size distribution analysis, and burst release profile of paclitaxel (PTX) from polymeric micelles upon the exposure to NIR irradiation.
A novel system for separation and purification of egg pigments from the nondiapause red‐egg mutant Re‐nd in the silkworm, Bombyx mori

Published: July 2020

AbstractRe‐nd, which was induced from the wild‐type C108 by the chemical mutagen N‐methane‐N‐methylnitrourea, is a nondiapause red‐egg mutant of silkworm Bombyx mori. The special significance of the Re‐nd mutant is that it is an independent dominant mutant. The aim of this study was to establish the type of pigment responsible for the red coloration in the Re‐nd mutant eggs in silkworm. We compared the eggs of Re‐nd mutants with those of the other B. mori egg color strains and confirmed that the Re‐nd mutant is the only strain with red color and red pigment granules in nondiapause, showing this mutant belongs to the pigmentation in the serosa. We speculated that the red substance, which contributed to the bright red pigmentation for nondiapause eggs of the Re‐nd mutant, could potentially be a novel pigment according to its solubility, optimum absorption peak, and oxidation–reduction reaction. Moreover, we have successfully constituted the system for enrichment, extraction, and purification of the red substance responsible for the Re‐nd mutant, providing a new method for the separation and purification of other known and unknown pigments or substances.

Published: July 2020

AbstractThis article presents a case study of the remains of Kharaib al‐Dasht (Kuwait), a Late Islamic fishing village. Collaboration between archaeologists from Kuwait and Poland of the Kuwaiti–Polish Archaeological Mission led to a long‐term research project of this archaeological site. In this contribution we are presenting the results of a geographic information system (GIS)‐structured survey. Different archaeological and geographical methods used in this work, including orthorectification and georeferencing of historical aerial photographs, enabled us to conduct a more in‐depth analysis. The multi‐layer GIS study resulted in a comprehensive recognition of the archaeological landscape of the site, and also helped us to determine the sources of changes and possible threats to the heritage of Failaka Island.
Vaccine Hesitancy and Attributions for Autism among Racially and Ethnically Diverse Groups of Parents of Children with Autism Spectrum Disorder: A Pilot Study
Authors: Chang Jennifer , Kochel Robin 
Published: July 2020

Little is known about how racial/ethnic differences may influence attributions for autism spectrum disorder (ASD) and subsequent vaccine hesitancy, the latter of which refers to a continuum of concerns about vaccine safety that may lead to vaccine delays and/or refusals. Two hundred and twenty‐five parents of children with ASD who were enrolled in the SPARK cohort (Simons Foundation Powering Autism Research for Knowledge) completed the Parent Attitudes about Childhood Vaccines survey and the Revised Illness Perception Questionnaire. 28.9% of respondents (n = 65) were vaccine hesitant (PACV score ≥ 50). Significant differences were observed between proportions of vaccine‐hesitant parents (VHP) in the White sample and combined samples of color (Asian, Black, Latinx, Multiracial, and Other): 22.8% of the White sample (n = 39) versus 48.1% of the samples of color (n = 26). White, non‐hesitant parents more often agreed with the child's brain structure as a cause of their child's ASD, while White, VHP more often agreed with the deterioration of the child's immunity as a cause. All VHP (regardless of race) agreed more often with diet, their own decisions, and vaccines as causes. VHP of color more often agreed with accident or injury, environmental pollution, their own general stress, and their own emotional state as causes. Future work should examine this phenomenon in larger, diverse samples to further understand differences across specific racial/ethnic groups.Lay SummarySome parents of children with autism spectrum disorder (ASD) are vaccine hesitant, meaning they have concerns about vaccine safety and may delay/refuse vaccines. We examined possible racial/ethnic differences related to how common vaccine hesitancy is and which causes of ASD were typically endorsed among a sample of caregivers in the SPARK cohort (Simons Foundation Powering Autism Research for Knowledge). Higher proportions of parents of color were vaccine hesitant, and all vaccine‐hesitant parents agreed that “toxins in vaccines” were a cause of their child's ASD.

Metal‐Coordination Mediated Polyacrylate for High Performance Silicon Microparticle Anode
Authors: Woo Hyungsub , Gil Bumjin , Kim Jaewon , Park Kimin , Yun Alan Jiwan , Kim Jinhyun , Nam Seunghoon , Park Byungwoo 
Published: July 2020

AbstractAs opposed to nano‐Si anodes, Si‐microparticle (Si‐MP)‐based negative electrode is still in an immature stage due to the fragility of particles of which dimension is farther from the critical size of Si. In terms of binder chemistry, the established strategies for nano‐Si anode can be moderately transferred to designing functional binders for commercially available Si‐MP. However, only a few studies have reported acceptable electrochemical properties of Si‐MP in the level of designing novel‐binder systems. Herein, the ionically crosslinked polyacrylate (PANa0.8Fey) inspired by metallo‐supramolecular polymers is introduced as a binder for Si‐MP anode. Although cracking of Si‐MP is inevitable during cycles, the electrode components can effectively be confined within the supramolecular network, which reversibly adjusts its architecture via iron (Fe3+)‐carboxylate coordination. With appropriate compositions, the incorporation of ferric ion to sodium polyacrylate allows the Si‐MP to exhibit an excellent round‐trip capacity of ∼1400 mAh g−1 after 400 cycles. The resulting electrochemical performance is demonstrated by several correlated factors: (i) type of supramolecular interactions, (ii) effect of cations (Na+/Fe3+) on the conformation of polymer, and (iii) mechanical properties of the electrode.
Production of entomopathogenic nematodes in submerged monoxenic culture: A review
Authors: Cortés‐Martínez Carlos Inocencio , Chavarría‐Hernández Norberto 
Published: July 2020

AbstractMonoxenic liquid culture is the most suitable technology for scaling up to industrial production of entomopathogenic nematodes (EPNs); however, the variability of the yield production remains a current problem in the process. The aim of this study was to analyze the parameters and criteria for EPN production in liquid culture based on scientific and technological knowledge from the last two decades. While experimental research has permitted the yield production of Heterorhabditis bacteriophora (362 × 103 infective juveniles [IJs]/ml) and Steinernema carpocapsae (252 × 103 IJs/ml), simultaneously, theoretical approaches have contributed to the understanding of the culture process, based on biological parameters of the bacterium–nematode complex and hydrodynamic and rheological parameters of the complex gas–liquid–solid system. Under this interdisciplinary research approach, bioprocess and biosystem engineering can contribute to design the various control strategies of the process variables, increase the productivity, and reduce the variability that until now distinguishes the in vitro production of EPNs by the liquid culture.

AbstractBackgroundFluoroquinolone antibiotics are frequently utilized in pediatric oncology patients as prophylaxis or step‐down therapy following broad spectrum beta‐lactam therapy for febrile neutropenia. Concerns regarding neurotoxicity limit the use of these agents. No studies have evaluated the association between fluoroquinolone use and neurotoxicity in pediatric oncology patients receiving other neurotoxic agents such as vincristine.MethodsAn observational cohort study comprising patients aged 0‐18 at diagnosis enrolled on a prospective study for treatment of acute lymphoblastic leukemia (ALL) at a pediatric comprehensive cancer center between October 2007 and November 2018. Data for neuropathic pain and sensory or motor neuropathy were collected prospectively, and a Cox proportional hazards regression model was used to evaluate associations between administration of fluoroquinolone antibiotics during induction therapy and subsequent development of vincristine‐induced peripheral neurotoxicity (VIPN).ResultsA total of 598 participants were enrolled, including 338 (57%) who received fluoroquinolones during induction therapy; of these 470 (79%) were diagnosed with VIPN and 139 (23%) were diagnosed with high‐grade (Grade 3+) VIPN. On unadjusted analyses, and analyses adjusted for age and race, there was no evidence of an association between fluoroquinolone exposure and subsequent VIPN (hazard ratio [HR] 0.8, 95% CI 0.5‐1.04, P = .08) or high‐grade VIPN (HR 1.1, 95% CI 0.4‐2.2, P = .87).ConclusionsThe results of this observational study do not show an association between exposure to fluoroquinolone antibiotics during induction therapy for ALL and subsequent development of vincristine‐induced peripheral neuropathies, and suggest that a large increase in VIPN is unlikely.
Spiritual counselling mitigates loneliness and promotes affect balance for older empty nester couples: A study in some international cities
Authors: Pandya Samta P. 
Published: July 2020

AbstractThis article reports a study examining the impact of a spiritual counselling programme (SCP) on older empty nester couples' loneliness experiences and affect balance. Since empty nesters are usually couples with a greater likelihood of interdependence in the psychosocial domains, there is a need to examine interdependent effects or actor–partner interdependent effects of interventions. Twenty‐four online SCP sessions were conducted throughout the year with the intervention group couples who were assessed on loneliness and affect balance outcomes pre‐ and post‐test compared with couples in the waitlist control group. The impact of SCP was significant, with lower loneliness post‐test scores and higher affect balance for couples from Russian and European cities, Christians, those who were well educated, in good health, those who attended at least 75% of the SCP sessions and regularly practised at home. Number of SCP sessions attended and home practice mediated the relationship between demographic predictors and outcomes. Results of the actor–partner interdependence model analyses indicated that intervention group couples' post‐test outcome measure scores were mutually interdependent and associated. Wives whose husbands attended more SCP lessons and regularly practised at home were more likely to do so themselves. This investigation fills the gap in empty nest literature of examining the efficacy of a specifically designed intervention for empty nesters.

Published: July 2020

AbstractAimAlthough research and clinical definitions of psychotherapeutic competence have been proposed, less is known about the layperson perspective. The aim was to explore the views of individuals with different levels of psychotherapy experience regarding what—in their views—constitutes a competent therapist.MethodIn an online survey, 375 persons (64% female, mean age 33.24 years) with no experience, with professional experience, or with personal pre‐experience with psychotherapy participated. To provide low‐threshold questions, we first presented two qualitative items (i.e. “In your opinion, what makes a good/competent psychotherapist?”; “How do you recognize that a psychotherapist is not competent?”) and analysed them using inductive content analysis techniques (Mayring, 2014). Then, we gave participants a 16‐item questionnaire including items from previous surveys and from the literature and analysed them descriptively.ResultsWork‐related principles, professionalism, personality characteristics, caring communication, empathy and understanding were important categories of competence. Concerning the quantitative questions, most participants agreed with items indicating that a therapist should be open, listen well, show empathy and behave responsibly.ConclusionInvestigating layperson perspectives suggested that effective and professional interpersonal behaviour of therapists plays a central role in the public's perception of psychotherapy.
Iatrogenic atrial septal defect following the MitraClip procedure: A state‐of‐the‐art review
Authors: Kadado Anis John , Islam Ashequl 
Published: July 2020

AbstractWith an increase in number of patients undergoing percutaneous treatment of severe mitral regurgitation with MitraClip placement, the consequences of transseptal puncture resulting in iatrogenic atrial septal defects (iASDs) are being increasingly realized. Closure of iASDs following MitraClip therapy is not routinely performed, and no guidelines currently exist in managing this condition. While immediate hemodynamic and clinical compromise secondary to acute hypoxemia related to iASDs should be acutely managed with defect closure, the prevalence and consequences of long‐term iASDs are still unclear. Some studies have cited a potential improvement in hemodynamic outcomes as a result of iASDs; while others report potential inferior and even fatal outcomes. In this state‐of‐the‐art clinical review, we present the readers with the current data on the prevalence, outcomes, and potential management options of iASDs after MitraClip placement.
