Published: March 2023

La contaminación de los sistemas acuáticos de agua dulce constituye un problema ambiental recurrente en el ámbito mundial, que se agudiza cada vez más con la presencia frecuente de nuevos compuestos químicos, tal es el caso de los contaminantes emergentes, dentro de los cuales se incluyen los productos farmacéuticos. El objetivo de esta investigación fue estimar la capacidad de la especie jacinto de agua (Eichhornia crassipes) para remover del medio acuoso cinco fármacos altamente recetados y de venta libre como ciprofloxacina, ibuprofeno, sulfametaxazol, diclofenaco y acetaminofén. El trabajo se llevó a cabo en condiciones de invernadero a una temperatura de 25 0C y a un pH de 6,5; con una toma de muestras cada 24 h a diferentes concentraciones (3, 6, 9,12) mg/L.

Para el análisis de las muestras se utilizó Espectrofotometría UV-VIS con lectura directa de las absorbancias de cada uno de los fármacos.

Se empleó la metodología de superficies de respuesta para el análisis estadístico de los datos, lo que permitió determinar los modelos para establecer tiempos y concentraciones óptimas maximizando la absorción de cada producto farmacéutico, así como obtener las pendientes de crecimiento para definir hacia donde se puede proyectar el óptimo.

Los principales resultados en este estudio indican que E. crassipes removió 95% de diclofenaco en soluciones acuosas con una concentración de 3 mg/L en un tiempo de 24 h, seguido de ciprofloxacina y acetaminofén con una remoción máxima de 91,18% y 71% a las 96 h, respectivamente. Mientras que los más bajos porcentajes de remoción se obtuvo para ibuprofeno y sulfametaxazol con 57,56% y 36%, respectivamente.

En el presente estudio, se comprobó la alta capacidad de remoción E. crassipes de los cinco productos farmacéuticos en condiciones controladas, evidenciando una gran posibilidad de aplicación en el campo de la fitorremediación de contaminantes emergentes en medio acuoso, lo cual constituye un importante aporte en este ámbito de la investigación.

This study was conducted to mitigate the adverse effects of sodium chloride stress on the reproductive parameters of tomatoes. This experiment was conducted in the greenhouse of the laboratory of tropical horticultural science, department of International agricultural development, Tokyo University of Agriculture. The design was a factorial CRD (completely randomized design) with five sodium chloride (0 mM, 50 mM, 100 mM, 150 mM, and 200 mM) treatments and four primings (0 MPa, 0.4 MPa, 0.8 MPa, and 1.2 MPa) treatments. Micro-Tom seeds were soaked in polyethylene glycol (PEG6000). Salinity was applied through irrigation water when the first flower bloomed. Reproductive-related parameters such as the number of flowers per plant, pollen viability, pollen germination, pollen tube length, number of fruits per plant, fruits size and yield per plant were measured. It was observed that salinity affected the tomato plants severely during the flowering stage, and many flowers did not bear fruit due to the decrease in pollen viability. In addition, electrolyte leakage increased under salt stress, while priming decreased this parameter. Priming improved the number of flowers, pollen viability, and fruits per plant. The best priming treatments were 0.8 MPa and 1.2 MPa for promoting and enhancing tolerance in the reproductive stage.

Keywords: physiology, priming, pollen viability, reproductive stage, and salinity.
Understanding Patient Beliefs in Using Technology to Manage Diabetes: Path Analysis Model From a National Web-Based Sample
Authors: Zahed Karim , Mehta Ranjana , Erraguntla Madhav , Qaraqe Khalid , Sasangohar Farzan
Published: March 2023

Background

 With 425 million individuals globally living with diabetes, it is critical to support the self-management of this life-threatening condition. However, adherence and engagement with existing technologies are inadequate and need further research.

Objective

 The objective of our study was to develop an integrated belief model that helps identify the significant constructs in predicting intention to use a diabetes self-management device for the detection of hypoglycemia.

Methods

 Adults with type 1 diabetes living in the United States were recruited through Qualtrics to take a web-based questionnaire that assessed their preferences for a device that monitors their tremors and alerts them of the onset of hypoglycemia. As part of this questionnaire, a section focused on eliciting their response to behavioral constructs from the Health Belief Model, Technology Acceptance Model, and others.

Results

 A total of 212 eligible participants responded to the Qualtrics survey. Intention to use a device for the self-management of diabetes was well predicted (R2=0.65; F12,199=27.19; P<.001) by 4 main constructs. The most significant constructs were perceived usefulness (β=.33; P<.001) and perceived health threat (β=.55; P<.001) followed by cues to action (β=.17; P<.001) and a negative effect from resistance to change (β=−.19; P<.001). Older age (β=.025; P<.001) led to an increase in their perceived health threat.

Conclusions

For individuals to use such a device, they need to perceive it as useful, perceive diabetes as life-threatening, regularly remember to perform actions to manage their condition, and exhibit less resistance to change. The model predicted the intention to use a diabetes self-management device as well, with several constructs found to be significant. This mental modeling approach can be complemented in future work by field-testing with physical prototype devices and assessing their interaction with the device longitudinally.
Applications of Federated Learning in Mobile Health: Scoping Review
Authors: Wang Tongnian , Du Yan , Gong Yanmin , Choo Kim-Kwang Raymond , Guo Yuanxiong
Published: March 2023

Background

The proliferation of mobile health (mHealth) applications is partly driven by the advancements in sensing and communication technologies, as well as the integration of artificial intelligence techniques. Data collected from mHealth applications, for example, on sensor devices carried by patients, can be mined and analyzed using artificial intelligence–based solutions to facilitate remote and (near) real-time decision-making in health care settings. However, such data often sit in data silos, and patients are often concerned about the privacy implications of sharing their raw data. Federated learning (FL) is a potential solution, as it allows multiple data owners to collaboratively train a machine learning model without requiring access to each other’s raw data.

Objective

The goal of this scoping review is to gain an understanding of FL and its potential in dealing with sensitive and heterogeneous data in mHealth applications. Through this review, various stakeholders, such as health care providers, practitioners, and policy makers, can gain insight into the limitations and challenges associated with using FL in mHealth and make informed decisions when considering implementing FL-based solutions.

Methods

We conducted a scoping review following the guidelines of PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews). We searched 7 commonly used databases. The included studies were analyzed and summarized to identify the possible real-world applications and associated challenges of using FL in mHealth settings.

Results

A total of 1095 articles were retrieved during the database search, and 26 articles that met the inclusion criteria were included in the review. The analysis of these articles revealed 2 main application areas for FL in mHealth, that is, remote monitoring and diagnostic and treatment support. More specifically, FL was found to be commonly used for monitoring self-care ability, health status, and disease progression, as well as in diagnosis and treatment support of diseases. The review also identified several challenges (eg, expensive communication, statistical heterogeneity, and system heterogeneity) and potential solutions (eg, compression schemes, model personalization, and active sampling).

Conclusions

This scoping review has highlighted the potential of FL as a privacy-preserving approach in mHealth applications and identified the technical limitations associated with its use. The challenges and opportunities outlined in this review can inform the research agenda for future studies in this field, to overcome these limitations and further advance the use of FL in mHealth.

Authors: Tahsin Farah , Armas Alana , Kirakalaprathapan Apery , Kadu Mudathira , Sritharan Jasvinei , Steele Gray Carolyn
Published: March 2023

Background

Information and communications technologies (ICTs) are recognized as critical enablers of integrated primary care to support patients with multiple chronic conditions. Although ICT-enabled integrated primary care holds promise in supporting patients with complex care needs through team-based and continued care, critical implementation factors regarding what ICTs are available and how they enable this model are yet to be mapped in the literature.

Objective

This scoping review addressed the current knowledge gap by answering the following research question: What ICTs are used in delivering integrated primary care to patients with complex care needs?

Methods

The Arksey and O’Malley method enhanced by the work by Levac et al was used to guide this scoping review. In total, 4 electronic medical databases were accessed—MEDLINE, Embase, CINAHL, and PsycINFO—collecting studies published between January 2000 and December 2021. Identified peer-reviewed articles were screened. Relevant studies were charted, collated, and analyzed using the Rainbow Model of Integrated Care and the eHealth Enhanced Chronic Care Model.

Results

A total of 52,216 articles were identified, of which 31 (0.06%) met the review’s eligibility criteria. In the current literature, ICTs are used to serve the following functions in the integrated primary care setting: information sharing, self-management support, clinical decision-making, and remote service delivery. Integration efforts are supported by ICTs by promoting teamwork and coordinating clinical services across teams and organizations. Patient, provider, organizational, and technological implementation factors are considered important for ICT-based interventions in the integrated primary care setting.

Conclusions

ICTs play a critical role in enabling clinical and professional integration in the primary care setting to meet the health system–related needs of patients with complex care needs. Future research is needed to explore how to integrate technologies at an organizational and system level to create a health system that is well prepared to optimize technologies to support patients with complex care needs.

Published: March 2023

Comparamos la diversidad, estructura y composición de especies, así como los patrones de abundancia de anfibios y reptiles entre los cuatro tipos de vegetación más representativos de la Reserva de la Biosfera Ría Lagartos (RBRL). El estudio se desarrolló de septiembre de 2004 a julio de 2005. Realizamos muestreos bimensuales diurnos y nocturnos mediante búsquedas directas en transectos en vegetación de duna costera (DUN), petenes (PET), selva baja inundable (SBI) y selva mediana subperennifolia (SMS). Registramos un total de 1,401 individuos y 50 especies (14 de anfibios y 36 de reptiles). Los anfibios mostraron notables diferencias de diversidad de especies entre tipos de vegetación, donde SBI y SMS fueron los ambientes más importantes en cuando a la riqueza de especies y abundancia. La riqueza de reptiles fue superior en SBI, pero otros valores de diversidad fueron similares entre los tipos de vegetación. Encontramos diferencias en la estructura y composición de especies, indicando alta complementariedad entre ambientes. Registramos pocos anfibios en riesgo de acuerdo con listas nacionales e internacionales, pero un número alto de reptiles se encuentran amenazados de extinción (24%), entre ellas especies endémicas, y dos son introducidas. Nuestro estudio ofrece un conocimiento más profundo sobre los patrones de diversidad y composición de la herpetofauna y representa el primer trabajo con estos vertebrados en la RBRL desde su decreto como Área Natural Protegida en 1979.

Gymnophthalmidae is a highly diverse family of small to medium sized South American lizards. In Paraguay, seven species are currently known. Among these, Colobosaura modesta and Micrablepharus maximiliani are two poorly sampled species in the country: C. modesta was only recorded in two localities in Amambay and San Pedro Departments, whilst M. maximiliani was recorded in Central, Cordillera, Paraguarí and San Pedro Departments. During two field surveys in 2022 we captured one C. modesta and three M. maximiliani individuals. The C. modesta record is 134.7 km west from the nearest known locality, and it is the third confirmed locality in the country, the first in the Concepción Department and the first associated with the Humid Chaco. The M. maximiliani records are 81, 131 and 137 km north from the nearest known locality and are the first records from Concepción and Amambay Departments. We provide habitat characterization for where the lizards were found and discuss their conservation status in Paraguay.

Published: March 2023

The rock river frog Thoropa miliaris (Cycloramphidae) is a saxicolous species endemic to the Atlantic Forest. There is scarce literature on potential predators of this species, which is likely related to the difficulty of recording its predatory interactions. In this paper, we report opportunistic records of predation on T. miliaris by the snake Chironius laevicollis (Colubridae), spiders of the genus Ctenus (Ctenidae), and the bird Furnarius rufus (Furnariidae). In addition, we compiled the reports of predation on T. miliaris from current published data.

Authors: Little Emily E. , Bain Lisa , Hahn-Holbrook Jennifer
Published: March 2023

Objective: To evaluate the effectiveness of an ergonomic infant
carrier for increasing postpartum parent-infant physical contact and
reducing postpartum depression risk. Design: A randomized
two-arm, parallel-group trial. Setting: Study participants’
homes from February 2018 to June 2019. Population or Sample:
100 participants in an income-constrained urban community in the United
States. Methods: At 30-weeks gestation, 50 participants were
randomly assigned to receive an ergonomic infant carrier and instruction
on use (intervention), and 50 participants were assigned to a waitlist
(control). Follow-up data were collected at 6-weeks postpartum from 78
participants (intervention n = 41; waitlist control n =
37). Main Outcome Measures: Edinburgh Postpartum Depression
Scale (EPDS) score and extent of infant carrier utilization.
Results: Participants in the carrier condition reported using
their carriers for an average of 1.95 hours per day ( SD = 1.59)
with participants in the intervention condition using an infant carrier
significantly more often at 6-weeks (β = 2.69, SE = .347,
p < .001, 95% CI = 2.08-3.41). The intervention
group reported significantly fewer depressive symptoms at 6-weeks
postpartum than the waitlist control group (β = -.541, p = .042).
Participants who used an infant carrier more hours per day reported
significantly fewer depressive symptoms (β = -1.60, SE = .069,
p = .019, 95% CI = -.30 to -.025). Conclusions:
An infant carrier intervention reduced postpartum depression at 6-weeks
postpartum, with a significant dose-response association where increased
infant carrier use predicted decreased postpartum depression
symptomology. Funding: ErgoBaby donated all infant carriers
used in this study but did not participate in any part of the research.

A visible-light-induced acyl radical conjugate addition to
electron-deficient alkenes with acylsilane was realized by merging
photoredox and Lewis acid catalysis under mild reaction conditions.
Various tri- and tetra-substituted furans were obtained with good yield
(up to 97%) from α,β-unsaturated ketones. Based on the experimental
results and spectral analysis, a possible catalytic cycle involving
1,4-conjugate addition/ring-closure/arylation sequence was proposed.
Beyond that, 1,6-acyl radical conjugate addition to para-quinone
methides was also accomplished to deliver a series of α-aryl ketones by
using this synergistic catalysis protocol.
Design & Implementation of a Microcontroller-Based Mobile Detonator Initiation System
Authors: GÜRKAN Serkan , ALDEMİR Mevlâna Halit
Published: March 2023

Electro explosive devices (EEDs) are used in both military and civilian
applications to initiate explosives. Currently, the wireless solutions
used for initiating EEDs commonly use star network topology. As the
control distance in the star topology increases, so does the power
requirement and hence the weight of the batteries. In Additionally,
safety issues may arise when initiating EEDs over short distances when
low-power transceivers are used. In this study, a microcontroller-based
mobile system that uses mesh network topology to initiate EEDs was
proposed. Within the scope of this study, a system consists of an
initiation control unit, remote ignition units, a mobile device layer,
and a charge unit have been developed. EED initiation delays in the
proposed system can be programmed using a mobile device. Thus, the
expensive and extensive programming devices used in conventional
initiating systems are no longer required for wireless EED initiating
systems. In the developed system, the average communication distances of
the remote initiating units were 251, 154, and 104 m in outdoor, urban,
and indoor environments, respectively. Unlike conventional commercial
wireless initiating systems that use star network topology, a system
that prefers the mesh network topology can successfully initiate
detonators from 1882 meters outdoors, 1170 meters in urban areas, and
811 meters indoors. Technical capabilities of an EED have been added to
an electric detonator by means of using the developed mobile initiation
device, and the initiation delay could be configured over mobile
network.

ABSTRACT The advent of Cloud Computing has brought tremendous growth to businesses. Enterprises, known for their cost savings, flexible and scalable features, are better managed today. Unfortunately, high dependency on service providers, data security issues, and high set-up costs are becoming major issues along with low adoption rates in developing countries. Despite the infrastructure deficit, there is a need for studies to focus on theories of adoption and use. Therefore, this study aims to systematically review empirical studies on the adoption and use of cloud computing in general to identify relevant factors determining organizational intention to use, actual use, and the impact of cloud computing services on performance. This study investigated the causal factors responsible for the adoption, use and performance of cloud computing through a systematic literature review. This study examined 150 related studies in various databases such as IEEE Xplore, Emerald, Springer link and Science Direct. Thirty-six (36) main factors were identified and the results showed that thirteen factors appeared most frequently: top management support, relative advantage, compatibility, security, complexity, technology readiness, firm size, competitive pressure, trial, cost savings, Perceived usefulness, perceived ease of use and personal innovativeness. Most of these factors are related to technology. This study serves as a foundation for future research and advancement of theory development in the adoption, use, and performance of cloud computing. It also provides inside information on user preferences and is crucial for service providers, business owners and government. Keywords: Cloud Computing, adoption, systematic literature review, determinants, utilization, performance.
Cutaneous manifestations in patients with microscopic polyangiitis: two case reports and a minireview
Authors: Kawakami T , Soma Y , Saito C , Ogawa H , Nagahuchi Y , Okazaki T , Ozaki S , Mizoguchi M.
Published: March 2023

Microscopic polyangiitis is a systemic small vessel vasculitis, which often has cutaneous and musculoskeletal features. Microscopic polyangiitis is a member of the family of anti-neutrophil cytoplasmic auto-antibody (ANCA)-associated vasculitides and is strongly associated with anti-myeloperoxidase (MPO)-ANCA. Titres of MPO-ANCA may reflect disease activity and play a pathogenic role. Patients with microscopic polyangiitis usually present with erythematous macules on the extremities as the first cutaneous manifestation. Skin biopsy specimens from the erythema reveal small-sized vessels that are infiltrated with neutrophils, consistent with leukocytoclastic vasculitis, in the deep dermis to the subcutaneous fat tissue. The cutaneous involvement is present at an early stage of microscopic polyangiitis with other non-specific symptoms, such as arthralgias and myalgias. The initial cutaneous manifestations are important in early diagnosis of possible ANCA-associated vasculitides with elevated ANCA titres.

The aims of this research were: to determine the level of job satisfaction of employees in the Master of Management, Faculty of Economics and Business, Universitas Trisakti, Jakarta, INDONESIA; to find out what factors can affect employee job satisfaction; and to find out the factors of employee job satisfaction that are not optimal. The results of the research become input in formulating and establishing policies according to the expectations of employees, departments and faculties. The research method is a quantitative descriptive method using primary data from 20 employees. Because the population is relatively small (less than 30 people), the sample size is determined using a saturated/census sample. The results showed that the level of job satisfaction of employees is in the good category. Of the five dimensions of job satisfaction, Co-workers have the highest and Promotion Opportunities the lowest. From the research results it can be recommended that department and faculty leaders can: create/update job descriptions, create internal problem forms, consider pay performance, carry out job promotions based on performance appraisal, provide promotion opportunities to all employee based on fairness, determine the size of employee work productivity and achieving work targets quantitatively, as well as preparing employee performance appraisal programs that are agreed upon and well socialized.

Їх основне призначення полягає в забезпеченні для користувача постійного доступу до інформації, яка зберігається на їх носіях, та можливості безперервної обробки цієї інформації, що зумовлює необхідність постійної підтримки подібних систем у працездатному стані. Таким чином, комп’ютерна техніка належить до систем, які вимагають високого ступеня (рівня) надійності. Враховуючи, що рівень надійності будь-якої техніки в процесі її експлуатації постійно знижується, що зумовлено процесами старіння та зношування, визначення та прогнозування надійності є актуальним науково-технічним завданням. Одними з найбільш поширених методів визначення та прогнозування стану об’єкта в будь-який момент часу є ймовірнісно-фізичні методи, які базуються на застосуванні імовірнісних моделей для обробки статистичної інфор-мації, отриманої в процесі експлуатації, або випробування реальних фізичних об’єктів. Незалежно від типу комп’ютерної техніки, до її складу входять електронні, електричні та електромеханічні елементи, зі збереженням їх функціональних властивостей на весь період застосування. Відповідно до сучасних поглядів на роботу електронних, електричних та електромеханічних елементів комплексним фактором, що характеризує технічний стан елемента, є якісне проходження електричного сигналу через контактні з’єднання, яке визначається величиною контактного опору. Отримана математична модель щільності розподілу є двопараметричною функцією, параметри якої мають фізичну інтерпретацію у вигляді швидкості зміни контактного опору та середньоквадратичного відхилення швидкості.

The existing system of studying forensic medicine in higher medical schools in Ukraine is analyzed by the author. Based on their own experience of scientific and practical work, the authors came to the conclusion that this system needs to be adjusted. According to the authors, the adjustment should include a reorientation of the teaching of forensic medicine to students to study the most necessary amount of theoretical material that is necessary for the practical work of a specialist in the field of forensic medicine during investigative actions. The authors propose to consider mastering these practical skills as the main goal of studying forensic medicine at the undergraduate stage.
PEDAGOGIA DE MASSAS DO NEOCONSERVADORISMO
Authors: Romão José Eustáquio
Published: March 2023

Este trabalho tem como objeto a análise dos problemas conjunturais da realidade atual brasileira, mais especificamente as voltadas para o desvendamento do fenômeno denominado “bolsonarismo”, o qual parece escapar às ferramentas analíticas usadas até agora pelos cientistas sociais – mesmo dos inscritos no Materialismo Histórico-Dialético. Agregam-se nele categorias psicanalistas, na perspectiva analítica de Wilhelm Reich, quando escreveu A Psicologia de massas do fascismo, escrito na primeira metade do século XX, quando este psicanalista acertou e superou seus colegas marxistas, explicando o fenômeno das massas sob o nazi-fascismo.
Sociología y Política: relaciones, tensiones y conflictos.
Authors: Natapof Daniel Rubén
Published: March 2023

El artículo analiza la compleja relación entre sociología y política, planteada desde los orígenes de su creación, que continúa vigente, al igual que el propósito mismo de la disciplina científica en constante proceso de revisión y replanteo, doscientos años después.

Se pasa revista a una (necesariamente) parcial revisión de perspectivas de algunos de los fundadores de la disciplina, así como a autores contemporáneos y libros que han recorrido la pregunta central respecto del fin y la “utilidad” de la sociología. Los citados planteos, abordan siempre entre otros tópicos el de la relación entre sociología y política, entre la disciplina científica y la demanda social, entre ciencia y poder, por mencionar algunos de los interrogantes.

Se establecen posibles orígenes de la escisión entre el campo teórico y el del conocimiento aplicado, así como de una relación entre sociología y política que aún no ha respondido a las expectativas que la disciplina científica suscita desde su creación.

El artículo plantea asimismo, tanto en su análisis como en las posibles hipótesis, su postura en relación a la temática, postulando la impostergable necesidad de avanzar en tono crítico pero en un camino cierto, hacia la superación de una escisión que lejos de ser virtuosa niega alternativas valiosas de sinergia en pos del desarrollo.

Background:

An arteriovenous fistula (AVF) at the craniocervical junction (CCJ) is a rare vascular malformation. Definitive diagnosis and curative treatment of CCJ AVF are challenging.

Case Description:

A 77-year-old man presented with subarachnoid hemorrhage. Cerebral angiography showed an AVF at the CCJ, which drained into a radicular vein. The lesion was fed by a vertebral artery, anterior and lateral spinal arteries (LSAs), and the occipital artery (OA). There were two unique structures: the LSA originating from the posterior inferior cerebellar artery of the extracranial V3 segment and the OA feeding the shunt. Curative treatment involved two steps: endovascular embolization of feeders using Onyx and surgical shunt disconnection. Feeding arteries were blackened by Onyx, which helped identify the location of the shunt. The shunt was located behind the first cervical (C1) spinal nerve, and the draining vein was confirmed on the deep side of the nerve. A clip was applied to the draining vein distal to the shunt. Tiny vessels supplying the shunt were then coagulated referring to blackened arteries.

Conclusion:

A radicular AVF at the CCJ along the C1 spinal nerve had unique vascular structures. Definitive diagnosis and curative treatment were achieved by combining endovascular embolization using Onyx and direct surgery.
Structural Characterization and Bonding Analysis of [Hg{Fe(CO)5}2]2+ [SbF6]-2

Published: March 2023

The non-classical carbonyl complex [Hg{Fe(CO)5}2]2+ [SbF6]-2 is prepared by reaction of Hg(SbF6)2 and excess Fe(CO)5 in anhydrous HF. The single-crystal X-ray structure reveals a linear Fe-Hg-Fe moiety as well as an eclipsed conformation of the eight basal CO ligands. Interestingly, the Hg-Fe bond length of 2.5745(7) Angstrom is relatively similar to the corresponding Hg-Fe bonds in literature-known [Hg{Fe(CO)4}2]2- dianions (2.52-2.55 Angstrom) which intrigued us to analyze the bonding situation in both the dications and dianions with the EDA-NOCV method. Both species are best described as Hg(0) compounds which are also confirmed by the shape of the HOMO-4 and HOMO-5 of the dication and dianion, respectively, in which the electron pair is located mainly at the Hg. Furthermore, for the dication and the dianion the sigma-backdonation from Hg into the [Fe(CO)5]22+ or the [Fe(CO)4]22- fragment is the most dominant orbital interaction and surprisingly these interaction energies are also very similar even in absolute values. The fact that both iron-based fragments are missing two electrons explains their prominent sigma-acceptor properties.

An environmentally friendly method for creating sustainable alternatives to traditional aromatic-aliphatic polyesters is a valuable step towards resource-efficiency optimization. A library of furan-based block copolymers was synthesized via temperature-varied two-step polycondensation reaction in diphenyl ether using Candida antarctica lipase B (CAL-B) as biocatalyst where dimethyl 2,5-furandicarboxylate (DMFDCA), alpha,omega-aliphatic linear diols (a,o-ALD), and bio-based dimerized fatty acid diol (known as dilinoleic diol, DLD) were used as the starting materials. Nuclear magnetic spectroscopy (1H and 13C NMR), Fourier transform spectroscopy (FTIR) and gel permeation chromatography (GPC) were used to analyze the resulting copolymers. Additionally, crystallization behavior and thermal properties were studied using X-ray diffraction (XRD), digital holographic microscopy (DHM), and differential scanning microscopy (DSC). The results showed that the diol chain length of a,o-ALD used in the synthesis of poly(alkyl furanoate-co-dilinoleic furanoate) copolymers had a significant effect on the material molecular weight, thermal properties and crystalline structure.
Fast Proton Transport on Graphanol: Mechanistic Insights from Machine Learning and Lattice Models

Development of new materials capable of conducting protons in the absence of water is crucial for improving the performance, reducing the cost, and extending the operating conditions for proton exchange membrane fuel cells. We present detailed atomistic simulations showing that hydroxylated graphane, which we call graphanol, will conduct protons anhydrously with very low diffusion barriers. We developed a deep learning potential (DP) for graphanol that has near-density functional theory accuracy at a small fraction of the computational cost. We used our DP to calculate diffusion coefficients, estimate the diffusion barrier, and compute thermal fluctuations as a function of system size. We identified the mechanism for proton conduction on the surface of graphanol. We show that protons hop along Grotthuss chains containing several hydroxyl groups aligned such that hydrogen bonds allow for conduction of protons forward and backward along the chain without hydroxyl group rotation. Long-range proton transport takes place as new Grotthuss chains form by rotation of hydroxyl groups. Thus, the overall diffusion barrier consists of a convolution of the intrinsic proton hopping barrier and the intrinsic hydroxyl rotation barrier. Our results provide a set of design rules for developing new anhydrous proton conducting membranes with low diffusion barriers.
