Published: October 2019

Background

Universities around the world, including Malaysia, have attracted many international students from different countries. Research has reported that acculturative stress resulting from international students’ attempts to adjust to the cultures of host countries is one of the most challenging issues that affects their lives in general and academic lives in particular.

Objective

This study aims to examine the effectiveness of an educational intervention on acculturative stress among new postgraduate international students joining Malaysian public universities.

Methods

A cluster randomized controlled trial design with Malaysian public universities as the unit of randomization will be used in this study. Public universities will be randomized in a 1:1 ratio to be either in the intervention (educational program) or control group (waiting list). Participants in the intervention group will receive 7 sessions in 9 hours delivered by an expert in psychology and the researcher. The control group will receive the intervention once the 3-month follow-up evaluation is completed.

Results

The data will be analyzed using the generalized estimation equation with a confidence interval value of 95%; significant differences between and within groups are determined as P<.05. The results of the study underlie the effectiveness of educational program in decreasing acculturative stress of new international students and enabling them to cope with a new environment. The results of this study will contribute to previous knowledge of acculturative stress, acculturation, and adjustment of international students. Furthermore, such results are expected to play a role in raising university policy makers’ awareness of their postgraduate international students’ acculturative stress issues and how they can help them avoid such stress and perform well in their academic life.

Conclusions

We expect that the intervention group will score significantly lower than the wait-list group on the immediate and 3-month postintervention evaluation of acculturative stress and achieve a higher level of adjustment. Results will have implications for international students, policy makers at universities, the Malaysian Ministry of Higher Education, and future research.

The Effect of Smartphone Apps Versus Supervised Exercise on Physical Activity, Cardiorespiratory Fitness, and Body Composition Among Individuals With Mild-to-Moderate Mobility Disability: Randomized Controlled Trial
Authors: Berglind Daniel , Yacaman-Mendez Diego , Lavebratt Catharina , Forsell Yvonne
Published: October 2019

Background

Adequate levels of physical activity (PA) and good cardiorespiratory fitness (CRF) are associated with profound health benefits for individuals with mobility disability (MD). Despite the vast amount of research published in the field of PA interventions, little attention has been given to individuals with MD.

Objective

The aim of this study was to examine the efficacy of an app-based versus a supervised exercise and health coaching program to support adults with MD to increase levels of PA, CRF, and improve body composition.

Methods

Participants with self-perceived MD, aged 18 to 45 years, were included in this 12-week parallel-group randomized controlled trial and allocated at random to an app-based intervention, using commercially available apps—the Swedish Military training app (FMTK), the Acupedo walking app, and the LogMyFood food photography app—or a supervised exercise and health coaching intervention, including 1 weekly supervised exercise session and healthy lifestyle coaching. The primary outcome was the level of moderate-to-vigorous PA (MVPA) measured with accelerometers. Secondary outcomes included CRF measured by a submaximal test performed on a stationary bicycle and body composition measured by bioelectrical impedance. All outcomes were measured at baseline, 6 weeks, and 12 weeks. Linear mixed-effect models were used to assess the between-group differences, as well as the within-group changes through time, in each intervention group.

Results

A total of 110 participants with MD were randomized to an app-based intervention (n=55) or a supervised exercise and health intervention (n=55). The mean age of participants was 34.9 years (SD 6.1), and 81.8% (90/110) of the participants were women. CRF showed a moderate increase in both groups after 12 weeks—1.07 (95% CI –0.14 to 2.27) mL/kg/min increase in the app-based group and 1.76 (95% CI 0.70 to 2.83) mLkg/min increase in the supervised exercise group. However, the intention-to-treat analysis showed no significant differences between the groups in MVPA or CRF after 12 weeks. Waist circumference was significantly lower in the app-based intervention group.

Conclusions

Commercially available apps increased levels of CRF and improved body composition over 12 weeks to the same extent as supervised exercise sessions, showing that both are equally effective. However, neither the app-based intervention nor the supervised exercise intervention increased MVPA.

Dermatologists’ Adherence to the Latest Recommendations for Screening of Hydroxychloroquine Retinopathy in Saudi Arabia: Cross-Sectional Study
Authors: Mleeh Nouf Talal , Alzahrani Nujood Abdulwahed , Hariri Jehad Osama , Mortada Hatan Hisham , Algethami Mohammed Ridha
Published: October 2019

Background

Hydroxychloroquine (HCQ) has been used to manage many inflammatory skin conditions. Nevertheless, retinopathy continues to be its most significant adverse effect. The American Academy of Ophthalmology (AAO) recommends baseline ophthalmologic screening in the first year of HCQ treatment. However, a recent study found an inadequate awareness of the recommendations. Furthermore, limited data are available regarding the implementation of the recommendations among dermatologists.

Objective

The aim of this study was to assess dermatologists’ adherence to recommendations pertaining to their current practice regarding HCQ toxicity detection.

Methods

A self-administrated questionnaire was distributed between February 2 and May 4, 2018, among members of the Saudi Society of Dermatology. The questionnaire comprised demographic-related questions and questions pertaining to each physician’s routine practice about the follow-up of HCQ-treated patients.

Results

A total of 76 dermatologists completed the questionnaire. We achieved a response rate of 62.54%. More than half (43/76, 56%) of the dermatologists were male. Furthermore, more than half (41/76, 53%) of them reported treating 1 to 3 patients with HCQ during the last year. Furthermore, two-thirds (47/76, 61%) of them reported screening patients before initiating HCQ treatment. Regarding follow-up recommendations, 59% (45/76) of dermatologists reported yearly after starting treatment for no-risk patients, whereas 94% (72/76) reported “yearly within 5 years of treatment” for at-risk patients. Data were considered significant at P<.05. All analyses were performed using SPSS, version 20 (IBM).

Conclusions

Dermatologists in Saudi Arabia are not well informed about some aspects of the latest recommendations regarding screening for HCQ toxicity in terms of tests, follow-up timing, cessation of the drug, and causative agents. Therefore, we recommend conducting more studies in Saudi Arabia to determine the adherence of more physicians to the AAO recommendations. Furthermore, patient education regarding HCQ toxicity and increased patient awareness are recommended for effective and safe HCQ use.
Feasibility, Acceptability, and Impact of a Web-Based Structured Education Program for Type 2 Diabetes: Real-World Study
Authors: Poduval Shoba , Marston Louise , Hamilton Fiona , Stevenson Fiona , Murray Elizabeth
Published: October 2019

Background

Structured education for people with type 2 diabetes improves outcomes, but uptake is low globally. In the United Kingdom in 2016, only 8.3% of people who were referred to education programs attended the program. We have developed a Web-based structured education program named Healthy Living for People with type 2 Diabetes (HeLP-Diabetes): Starting Out (HDSO), as an alternative to face-to-face courses. A Web-based program gives people more options for accessing structured education and may help improve overall uptake.

Objective

The aim was to explore the feasibility and acceptability of delivering a Web-based structured education program (named HeLP-Diabetes: Starting Out) in routine primary health care and its potential impact on self-efficacy and diabetes-related distress.

Methods

HDSO was delivered as part of routine diabetes services in primary health care in the United Kingdom, having been commissioned by local Clinical Commissioning Groups. Quantitative data were collected on uptake, use of the program, demographic characteristics, self-reported self-efficacy, and diabetes-related distress. A subsample of people with type 2 diabetes and health care professionals were interviewed about acceptability of the program.

Results

It was feasible to deliver the program, but completion rates were low: of 791 people with type 2 diabetes registered, only 74 (9.0%) completed it. Completers improved their self-efficacy (change in median score 2.5, P=.001) and diabetes-related distress (change in median score 6.0, P=.001). Interview data suggested that the course was acceptable, and that uptake and completion may be related to nonprioritization of structured education.

Conclusions

The study provides evidence of the feasibility and acceptability of a Web-based structured education. However, uptake and completion rates were low, limiting potential population impact. Further research is needed to improve completion rates, and to determine the relative effectiveness of Web-based versus face-to-face education.

Authors: Chen Jessica , Kaye Leanne , Tuffli Michael , Barrett Meredith A , Jones-Ford Shelanda , Shenouda Tina , Gondalia Rahul , Henderson Kelly , Combs Veronica , Van Sickle David , Stempel David A
Published: October 2019

BACKGROUND

Digital health programs assist patients with chronic obstructive pulmonary disease (COPD) to better manage their disease. Technological and adoption barriers have been perceived as a limitation.

OBJECTIVE

The aim of the research was to evaluate a digital quality improvement pilot in Medicare-eligible patients with COPD.

METHODS

COPD patients were enrolled in a digital platform to help manage their medications and symptoms as part of their routine clinical care. Patients were provided with electronic medication monitors (EMMs) to monitor short-acting beta-agonist (SABA) use passively and a smartphone app to track use trends and receive feedback. Providers also had access to data collected via a secure website and were sent email notifications if a patient had a significant change in their prescribed inhaler use. Providers then determined if follow-up was needed. Change in SABA use and feasibility outcomes were evaluated at 3, 6, and 12 months.

RESULTS

A total of 190 patients enrolled in the pilot. At 3, 6, and 12 months, patients recorded significant reductions in daily and nighttime SABA use and increases in SABA-free days (all P<.001). Patient engagement, as measured by the ratio of daily active use to monthly active use, was >90% at both 6 and 12 months. Retention at 6 months was 81% (154/190). Providers were sent on average two email notifications per patient during the 12-month program.

CONCLUSIONS

A digital health program integrated as part of standard clinical practice was feasible and had low provider burden. The pilot demonstrated significant reduction in SABA use and increased SABA-free days among Medicare-eligible COPD patients. Further, patients readily adopted the digital platform and demonstrated strong engagement and retention rates at 6 and 12 months.
The Psychometric Properties of the Chinese eHealth Literacy Scale (C-eHEALS) in a Chinese Rural Population: Cross-Sectional Validation Study (Preprint)
Authors: Ma Zhihao , Wu Mei
Published: October 2019

BACKGROUND

The eHealth Literacy Scale (eHEALS) is the most widely used instrument in health studies to measure individual’s electronic health literacy. Nonetheless, despite the rapid development of the online medical industry and increased rural-urban disparities in China, very few studies have examined the characteristics of the eHEALS among Chinese rural people by using modern psychometric methods. This study evaluated the psychometric properties of eHEALS in a Chinese rural population by using both the classical test theory and item response theory methods.

OBJECTIVE

This study aimed to develop a simplified Chinese version of the eHEALS (C-eHEALS) and evaluate its psychometric properties in a rural population.

METHODS

A cross-sectional survey was conducted with 543 rural internet users in West China. The internal reliability was assessed using the Cronbach alpha coefficient. A one-factor structure of the C-eHEALS was obtained via principal component analysis, and fit indices for this structure were calculated using confirmatory factory analysis. Subsequently, the item discrimination, difficulty, and test information were estimated via the graded response model. Additionally, the criterion validity was confirmed through hypothesis testing.

RESULTS

The C-eHEALS has good reliability. Both principal component analysis and confirmatory factory analysis showed that the scale has a one-factor structure. The graded response model revealed that all items of the C-eHEALS have response options that allow for differentiation between latent trait levels and the capture of substantial information regarding participants’ ability.

CONCLUSIONS

The findings indicate the high reliability and validity of the C-eHEALS and thus recommend its use for measuring eHealth literacy among the Chinese rural population.
Privacy-Preserving Record Linkage of Deidentified Records Within a Public Health Surveillance System: Evaluation Study (Preprint)
Authors: Nguyen Long , Stoové Mark , Boyle Douglas , Callander Denton , McManus Hamish , Asselin Jason , Guy Rebecca , Donovan Basil , Hellard Margaret , El-Hayek Carol
Published: October 2019

BACKGROUND

The Australian Collaboration for Coordinated Enhanced Sentinel Surveillance (ACCESS) was established to monitor national testing and test outcomes for blood-borne viruses (BBVs) and sexually transmissible infections (STIs) in key populations. ACCESS extracts deidentified data from sentinel health services that include general practice, sexual health, and infectious disease clinics, as well as public and private laboratories that conduct a large volume of BBV/STI testing. An important attribute of ACCESS is the ability to accurately link individual-level records within and between the participating sites, as this enables the system to produce reliable epidemiological measures.

OBJECTIVE

The aim of this study was to evaluate the use of GRHANITE software in ACCESS to extract and link deidentified data from participating clinics and laboratories. GRHANITE generates irreversible hashed linkage keys based on patient-identifying data captured in the patient electronic medical records (EMRs) at the site. The algorithms to produce the data linkage keys use probabilistic linkage principles to account for variability and completeness of the underlying patient identifiers, producing up to four linkage key types per EMR. Errors in the linkage process can arise from imperfect or missing identifiers, impacting the system’s integrity. Therefore, it is important to evaluate the quality of the linkages created and evaluate the outcome of the linkage for ongoing public health surveillance.

METHODS

Although ACCESS data are deidentified, we created two gold-standard datasets where the true match status could be confirmed in order to compare against record linkage results arising from different approaches of the GRHANITE Linkage Tool. We reported sensitivity, specificity, and positive and negative predictive values where possible and estimated specificity by comparing a history of HIV and hepatitis C antibody results for linked EMRs.

RESULTS

Sensitivity ranged from 96% to 100%, and specificity was 100% when applying the GRHANITE Linkage Tool to a small gold-standard dataset of 3700 clinical medical records. Medical records in this dataset contained a very high level of data completeness by having the name, date of birth, post code, and Medicare number available for use in record linkage. In a larger gold-standard dataset containing 86,538 medical records across clinics and pathology services, with a lower level of data completeness, sensitivity ranged from 94% to 95% and estimated specificity ranged from 91% to 99% in 4 of the 6 different record linkage approaches.

CONCLUSIONS

This study’s findings suggest that the GRHANITE Linkage Tool can be used to link deidentified patient records accurately and can be confidently used for public health surveillance in systems such as ACCESS.

Published: October 2019

Aim:
Medicaid versus private primary insurance status may predict in-hospital mortality and morbidity after total knee arthroplasty (TKA).
Materials & methods:
Regression models were used to test our hypothesis in patients in the State Inpatient Database (SID) from five states who underwent primary TKA from January 2007 to December 2014.
Results:
Medicaid patients had greater odds of in-hospital mortality (odds ratio [OR]: 1.73; 95% CI: 1.01–2.95), greater odds of any postoperative complications (OR: 1.25; 95% CI: 1.18–1.33), experience longer lengths of stay (OR: 1.09; 95% CI: 1.08–1.10) and higher total charges (OR: 1.03; 95% CI: 1.02–1.04).
Conclusion:
Medicaid insurance status is associated with higher in-hospital mortality and morbidity in patients after TKA compared with private insurance.

Pangkah Wetan village has begun to utilize mangrove forests. At present, mangrove forests have been developed as ecotourism objects, however, the management has not developed them maximally. This study aims to determine the strengths, weaknesses, opportunities, and threats, as well as to analyze the strategies used in developing ecotourism at Muara Bengawan Solo Mangrove. Six key informants were selected as resource persons, while 30 respondents were selected by accidental sampling, they became the subject of analysis. The tool used is SWOT analysis (Strength, Weakness, Opportunity, Threat) and Quantitative Strategic Planning Matrix (QSPM). The results shows that the biggest score 1.84  was obtained at the opportunity, while the threat score was 0.84 so that this mangrove ecotourism still has many opportunities that could be used in developing ecotourism. The scores of strengths and weaknesses are 1.62 and 1.22, with a score difference of 0.4 only. The strength is only a slight difference from its weaknesses. Based on QSPM, an alternative strategy is obtained with the highest score of 5.71% at the first alternative. Application of the strategy used in developing mangrove ecotourism is the improvement of facilities provided to visitors.

Published: October 2019

The aim of our investigation is to derive a particular theory among the class
of scalar-tensor(ST) theories of gravity, and then to test it by studying
kinematics and dynamics of S-stars around a supermassive black hole (BH) at
Galactic Center (GC). We also discuss the Newtonian limit of this class of
ST theories of gravity, as well as its parameters. We compare the observed
orbit of S2 star with our simulated orbit which we obtained theoretically
with the derived ST potential and constrained parameters. Using the obtained
best-fit parameters we calculated orbital precession of S2 star in ST
gravity and found that it has the same direction as in General Relativity
(GR) but causes much larger pericenter shift.
Preparation and characterizations of three-dimensional porous collagen/graphene oxide/hydroxyapatite nanocomposite scaffolds for bone tissue engineering
Authors: Zimba Bhahat Lawlley , Hao Jiang , Li Chen , Yaomin Li , Xunzhi Yu , Chang Chen , Jiangling Wan , Wu Qingzhi
Published: October 2019

Studies have reported that the incorporation of graphene oxide (GO) and hydroxyapatite (HA) into biocompatible polymers (such as collagen (Col), chitosan, alginate, etc) results in enhanced structural and mechanical properties respectively. The objective of this study was to prepare and characterize three-dimensional (3D) porous Col/GO/HA nanocomposite scaffolds and to investigate cytocompatibility and osteogenic differentiation potential of rat bone marrow mesenchymal stem cells (rBMSCs) on the as-prepared scaffolds. The SEM images revealed that the scaffolds were porous with the pore diameter inversely proportional to the concentration of HA. XRD results were able to depict the characteristic peaks for HA which shows that HA was incorporated into the scaffolds. The rBMSCs which were cultured on the scaffolds were able to attach and proliferate during the 21 days of the experiment which indicates that the as-prepared scaffolds are cytocompatible. The Alizarin red staining demonstrated the presence of calcium deposits as there were orange-red stains on the samples after culturing the cells using the osteogenic differentiation medium. These results demonstrate the promising potential of the 3D porous Col/GO/HA nanocomposite scaffolds for applications in bone tissue engineering.
Achieving Wellbeing and Prosocial Transformation Through Social Mobilisation: An Evaluation of a Gang Empowerment Strategy
Authors: Roguski Michael
Published: October 2019

Adult gangs hold a criminalised and deviantised position in Aoteaora/New Zealand.  Further, a host of strategies have been enacted to remove or obliterate the ‘gang problem’.  These strategies’ lack of efficacy can be attributed to the imposition deficit-based criminogenic constructions on populations that are misunderstood and continually othered.  The current study documents an evaluation of a gang-driven social mobilisation initiative.  Identified outcomes are linked to the rejection of deficit and criminogenic epistemology in favour of a holistic appreciation of the socio-historical self.  Criminogenic strategies have been found to entrench gang membership.  In contrast, a holistic appreciation provides a foundation for social mobilisation where the membership is best placed to respond to their own needs.

Published: October 2019

Neste artigo é apresentada parte de uma pesquisa que foi realizada para compreender o processo de aprendizagem de matemática por estudantes surdos focando as especificidades da Linguagem Matemática. A investigação foi desenvolvida em uma escola bilíngue, com um grupo de estudantes surdos do 1o ano do Ensino Médio. Os dados analisados foram coletados por meio de entrevistas semiestruturadas, filmagens das aulas e protocolos das atividades realizadas pelos estudantes. Para este artigo foram selecionadas duas atividades, que tiveram como objetivo inserir a Linguagem Matemática por meio do estudo algébrico, envolvendo a noção de variação e dependência entre grandezas, de regularidade e de generalização. A partir da análise dos dados é possível afirmar que a sinalização das atividades em Libras é um fator decisivo para a compreensão dos enunciados e estratégias na resolução das atividades pelos estudantes; a comunicação entre os estudantes, e entre os estudantes e professor por meio da Língua Brasileira de Sinais – (LIBRAS) favoreceu a resolução das atividades. Em relação à escrita da Língua Portuguesa, todos os estudantes conseguiram registrar suas estratégias para a resolução das atividades, mas utilizando a lógica de registro baseado em LIBRAS, portanto o conhecimento do professor desta língua possibilitou a compreensão das respostas escritas pelos estudantes.
Contributos da Didática Profissional na formação de professores: um estudo sobre conjuntos numéricos

Published: October 2019

No Brasil quando pretende-se investigar sobre o ensino e aprendizagem no campo da Matemática, existe uma forte herança francesa advinda da Didática da Matemática. Todavia, quando surge a preocupação em analisar a atividade e a competência do professor de Matemática, a Didática da Matemática não desenvolve tais premissas. No entanto, uma vertente francesa da década de 90 tida como Didática Profissional ajuda a compreender essa lacuna. Por esse viés, esse trabalho procurou como referência a Didática Profissional juntamente com a Didática da Matemática para investigar um cenário novo no que se refere a competência e habilidade do professor de Matemática, voltada para um sistema de ensino. Portanto, o objetivo desse trabalho se encontra em aderir os elementos da Didática Profissional para categorizar a concepção dos professores em formação continuada e formação inicial a respeito dos conjuntos numéricos, a partir de uma entrevista semiestruturada. Para tal finalidade, os dados oriundos obtidos mostraram como as categorias dos professores se enquadram nos termos investigativos da Didática Profissional. Dessa forma, o presente trabalho aponta um desenvolvimento acerca da aprendizagem do professor a partir do trabalho.
Determination of insecticide imidacloprid residues in Tokat city water by using enzyme-linked immunosorbant assay (ELISA)
Authors: ŞENGÜL DEMİRAK Meryem Şenay
Published: October 2019

Imidacloprid is a common neonicotinoid insecticide applied in agricultural fields worlwide. Imidacloprid residues can be detected in water resources as it can accumulate in the surface and ground water after insecticide applications through many years. Because of this, a fast and efficient method, enzyme-linked immunosorbant assay (ELISA), is used to determine the imidacloprid levels in water sample collected from Tokat city water system and compared with a commercially avaliable bottled water sample. Imidacloprid residue was not detected in bottled water sample. However, imidalcoprid residues was detected in Tokay city water close to the maximum residue limit of imidacloprid. The results indicate that the Tokat city water system could be at the risk of imidacloprid contamination. This study also shows that ELISA technique can be effectively used for imidacloprid determination since it is fast and reliable and well correlated with other time consuming and cost-effective analytical methods.

Synthesis of Germanosilicate Zeolite HPM-12 Using a Short Imidazolium-based Dication: Structure-Direction by Charge-to-Charge Distance Matching
Authors: Lu Peng , Gómez-Hortigüela Luis , Gao Zihao , Camblor Miguel
Published: October 2019

A short imidazolium based dication, with only three methylene units in the space linker, selectively directs the crystallization towards zeolite HPM-12 (*UOE) as long as there is enough germanium present in the synthesis gel. The integrity of the dication is proved by dissolution of the zeolite and 1H and 13C NMR spectroscopy, where significant effects of organic concentration and presence and concentration of HF need to be taken into account. In the as-made HPM-12 zeolite, a large shift of 9 ppm of one resonance in the 13C MAS NMR is due to the particular conformation of the dication imposed by confinement in the zeolite framework, as found by DFT calculations. The structure-directing ability of this kind of dications with varying length of the linker suggests that matching of the distance between positive charges (imidazolium moieties) and negative charges (double four rings in which fluoride resides) plays a crucial role during crystallization.

Direct C–H Alpha Arylation of Enones with ArI(O2CR)2 Reagents
Authors: Sousa e Silva Felipe Cesar , Van Nguyen T , Wengryniuk Sarah
Published: October 2019

Herein, we report the metal-free direct C–H arylation of enones mediated by hypervalent iodine reagents. The reaction proceeds via a reductive iodonium Claisen rearrangement of in situ b-pyridinium silyl enol ethers. The aryl groups are derived from ArI(O2CCF3)2 reagents, which are readily accessed from the parent iodoarenes. It is tolerant of a wide range of substitution patterns and the incorporated arenes maintain the valuable iodine functional handle. Mechanistic investigations implicate arylation via an umpoled “enolonium” species and that the presence of a b-pyridinium moiety is critical for desired C–C bond formation.

Published: October 2019

Plasmonic particles can be welded together, but controlling the metallurgy of the hotspots is a challenge in colloidal chemistry. In this paper, we demonstrate an original method that connects gold particles to their neighbors by another metal of choice. To achieve this goal, we first assemble gold bipyramids in a tip-to-tip configuration, yielding short chains of variable length. The good colloidal stability and surface accessibility make the nanochains suitable seeds to grow metallic junctions in a second step. We follow the oligomer formation and the deposition of the second metal (i.e. silver or palladium) via UV/Vis spectroscopy and we map the plasmonic properties of the nanostructures at nanometer scale using electron energy loss spectroscopy. The formation of silver bridges leads to a huge redshift of the longitudinal plasmon modes into the mid-infrared region, while the addition of palladium results in a redshift accompanied by significant plasmon damping.

Iron- and nitrogen-doped carbon (Fe-N-C) materials are leading candidates to replace platinum in fuel cells, but their active site structures are poorly understood. A leading postulate is that iron active sites in this class of materials exist in an Fe-N4 pyridinic ligation environment. Yet, molecular Fe-based catalysts for the oxygen reduction reaction (ORR) generally feature pyrrolic coordination and pyridinic Fe-N4 catalysts are, to the best of our knowledge, non-existent. We report the synthesis and characterization of a molecular pyridinic hexaazacyclophane macrocycle, (phen2N2)Fe, and compare its spectroscopic, electrochemical, and catalytic properties for oxygen reduction to a prototypical Fe-N-C material and iron octaethylporphyrin, (OEP)Fe, a prototypical pyrrolic iron macrocycle. N 1s XPS signatures for coordinated N atoms in (phen2N2)Fe are positively shifted relative to (OEP)Fe, and overlay with those of Fe-N-C. Likewise, spectroscopic XAS signatures of (phen2N2)Fe are distinct from those of (OEP)Fe, and are remarkably similar to those of Fe-N-C with compressed Fe–N bond lengths of 1.97 Å in (phen2N2)Fe that are similar to the average 1.94 Å length in Fe-N-C. Electrochemical data indicate that the iron center in (phen2N2)Fe is relatively electropositive, with an Fe(III)-OH/Fe(II)-OH2 potential at 0.59 V vs the reversible hydrogen electrode (RHE), ~300 mV positive of (OEP)Fe. This correlates with a 300 mV positive shift in the onset of ORR catalysis for (phen2N2)Fe with a corresponding 1400-fold increase in TOF relative to (OEP)Fe. Consequently, the ORR onset for (phen2N2)Fe is within 150 mV of Fe-N-C. Unlike (OEP)Fe, (phen2N2)Fe displays excellent selectivity for 4-electron ORR with <4% maximum H2O2 production, comparable to Fe-N-C materials. This study establishes a pyridinic iron macrocycle that effectively models Fe-N-C active sites and provides a rich platform for constructing high-performance Fe-based oxygen reduction catalysts.
Catalytic Asymmetric Radical-Polar Crossover Hydroalkoxylation
Authors: Discolo Christopher , Touney Eric , Pronin Sergey
Published: October 2019

Asymmetric intramolecular hydrofunctionalization of tertiary allylic alcohols is described. This metal hydride-mediated catalytic radical-polar crossover reaction delivers corresponding epoxides in good to high enantioselectivity and constitutes the first example of asymmetric hydrogen atom transfer-initiated process. A series of modified cobalt salen complexes has proven optimal for achieving good efficiency and asymmetric induction. Experimental data suggest that cationic cobalt complexes are involved in enantio-determining step, where cation–π interactions in the catalyst contribute to the asymmetric induction.

Polymers comprised of redox-active organic radicals have emerged as promising materials for use in a variety of organic electronics, including fast-charging batteries. Despite these advances, relatively little attention has been focused on the diversification of the families of radicals that are commonly incorporated into polymer frameworks, with most radical polymers being comprised of nitroxide radicals. Here, we report two new examples prepared via ring-opening methathesis polymerization containing 6-oxoverdazyl and nitronyl nitroxide radicals appended to their backbones. The polymerization reaction and optoelectronic properties were explored in detail, revealing high radical content and redox activity that may be advantageous for their use as semiconducting thin films. Initial studies revealed that current-voltage curves obtained from thin films of the title polymers exhibited memory effects making them excellent candidates for use in resistive memory applications.
