Pavement grade cationic bitumen emulsions formulations were developed for Slurry Surfacing based on orthophosphoric and hydrochloric acids with both all-purpose and specialized emulsifiers used. As a result, there were established relations of mix time upon cement - for Slurry Surfacing based on various acids and emulsifiers. Mix time of Slurry Surfacing mix (having different cement content) with bitumen emulsions on both orthophosphoric and hydrochloric acids is characterized by parabolic relation, branches of the parabola going down. Still, parabola slope steepness for Slurry Surfacing with cement and bitumen emulsions on orthophosphoric acid is higher than for emulsions on hydrochloric acid. The regularity investigated allows affirming that dosing cement for Slurry Surfacing with orthophosphoric-based bitumen emulsions shall be more diligently checked and controlled – so as to avoid the premature mix time.

Published: November 2023

In the post-war period, Ukraine will need a large number of aggregates to repair and rebuild destroyed and damaged objects of transport infrastructure, including roads, airfields, and parking lots. To expand the raw material base of such construction, in addition to traditional high-quality aggregates from crushed granite, quartz sand and manufactured sand, it is advisable to use some types of waste and secondary products from various industries. They must meet the basic requirements for density, strength, frost resistance. These include a by-product of iron ore mining, quartzite. The use of quartzites as aggregates for cement concretes has certain difficulties due to their characteristics. This is reflected, first of all, on the strength of the concretes in which they are included. In this article, the features of the influence of quartzite aggregates on the strength of cement concretes are considered. Studies that have been carried out on mixtures of different mobility have shown that dusty particles, which are part of quartzite, have a positive effect on the structure of concrete.

Published: November 2023

The Depok Single Window (DSW) application is a media portal in the form of e-Government which was initiated by the Depok City Communication and Information Department to make it easier for people to get services and can also support the smart city concept. The background to this research is that many people in Depok City are not aware of the existence of the Depok Single Window (DSW) application, and there are still several services provided by each OPD that have not been integrated, as well as many complaints from the public. There was a decrease in the level of use of the Depok Single Window (DSW) application. The purpose of this research is to determine the evaluation of the Depok Single Window (DSW) application in supporting the Smart City Concept in the Depok City Communication and Information Department. The method used is a descriptive qualitative method by conducting interviews, observation and documentation. There are 6 (six) dimensions consisting of effectiveness, efficiency, adequacy, alignment, responsiveness and accuracy. The data source used is primary data obtained directly from informants and observations. Secondary data comes from existing data from the Depok City Communication and Information Office as well as documents. The results of the research show that the evaluation of the Depok Single Window (DSW) application has been carried out sufficiently to support the smart city concept in the Depok City Communication and Information Department, which is a form of smart government. However, implementation is still not optimal. There are still quite a lot of people in Depok City who don't know about it and there are still several obstacles experienced by people in using it. It was concluded that the evaluation of the Depok Single Window (DSW) application had been carried out but had not been carried out optimally.

« Nous sommes uniques » : facteurs de stress organisationnels, soutien par les pairs et attitudes à l’égard des soins de santé mentale chez les pompiers d’aéroport
Authors: Barry Bridget , Ricciardelli Rosemary , Cramm Heidi
Published: November 2023

Introduction

Les pompiers d’aéroport ont la responsabilité de fournir des services d’intervention d’urgence en cas d’incidents aéronautiques sur une piste d’atterrissage ou à proximité d’un aéroport, que ce soit en cas d’écrasement d’avion, d’incident faisant un grand nombre de victimes, d’atterrissage d’urgence ou de nombreux autres problèmes survenant sur les terrains de l’aéroport. Bien qu’il existe des données sur les facteurs de stress professionnels des pompiers et du personnel de la sécurité publique en général, il y a un manque de connaissances concernant les expériences des pompiers d’aéroport, en particulier en ce qui concerne leurs facteurs de stress organisationnels, le soutien par leurs pairs et leur attitude à l’égard des soins de santé mentale.

Méthodologie

En 2019, nous avons dirigé deux groupes de discussion regroupant dix pompiers professionnels travaillant dans un aéroport du Canada atlantique. Les discussions ont été enregistrées et les enregistrements transcrits puis codés par analyse thématique à l’aide d’une méthode narrative, itérative et inductive.

Résultats

Les pompiers d’aéroport sont confrontés à des défis spécifiques et les facteurs de stress opérationnels sont occultés par les facteurs de stress organisationnels. De plus, le soutien par les pairs est un aspect intégral de la gestion des facteurs de stress organisationnels et des incidents critiques. On a constaté que les pompiers avaient une attitude positive à l’égard des soins de santé mentale en général, mais plusieurs obstacles subsistent, en particulier la stigmatisation, la crainte d’être mis en congé et la crainte d’une violation de la confidentialité.

Conclusion

Des options de traitement spécialisées sont nécessaires pour le personnel de la sécurité publique et les pompiers d’aéroport qui interviennent en cas d’incidents graves en dehors de leurs fonctions habituelles.

When second language learners have language anxiety especially when they are using the speaking skills, they are more likely to experience anxiety, self-doubt, frustration, and fear that will affect their ability to learn the languages. However, based on previous research, it is shown that learners' anxiety over public speaking significantly decreased when gamification was included in the classroom. Therefore, in this study, the main objective was to explore the students’ perception towards the gamification setting in reducing speech anxiety among UiTM students. The study employs a quantitative study with 221 participants consisting of undergraduates from various faculties in UiTM. A descriptive analysis was used to analyze the data. From the results, it is found that most of the students experienced a level of anxiety in the beginning despite using the virtual gamification setting. However, they believe that the virtual speech application helped them in getting an improved positive experience when delivering a speech, particularly in easing their anxiousness upon speaking in front of an audience.
A new bipolar precordial electrocardiographic lead configuration for specific evaluation of atrial depolarization in healthy dogs
Authors: Kurogochi Kentaro , Orito Kensuke , Uechi Masami
Published: November 2023

OBJECTIVE

The Lewis lead is an EGC configuration used to detect atrial activity and its relationship with ventricular activity. However, no equivalent configuration has been proposed in veterinary medicine. Therefore, this study explored new bipolar lead configurations to evaluate atrial depolarization and investigated their characteristics by comparing them with conventional leads. The authors hypothesized that a lead with a high absolute value of the P wave (|P|) and a high ratio of the P wave to the QRS complex (|P|/|QRS|) might be an appropriate configuration.

ANIMALS

6 laboratory Beagles were used.

PROCEDURES

Electrocardiograms were recorded using bipolar limb leads (I, II, III, aVL, aVF, and aVR) and unipolar precordial leads (C2, C3, C4, C5, C6, M1, M2, M5, M6, 1st-R, CV6LL, and V10) in the standing position. The new bipolar leads were attached in the following configuration: the negative electrode was attached to M6, and the positive electrode was sequentially applied to M1 and M2. The leads were named M6M1 and M6M2.

RESULTS

The waveforms obtained using the new bipolar leads M6M1 and M6M2 showed significantly higher |P|/|QRS| and |P| values than those obtained using conventional limb leads and precordial leads.

CLINICAL RELEVANCE

The new leads achieved a specific enhancement of atrial activity conducted at a reduced ventricular amplitude and increased atrial amplitude, similar to the Lewis lead in human medicine. These findings suggest that M6M1 and M6M2 could be supplemental lead configurations to identify P waves without amplifying the QRS waves compared to conventional methods.
The Size and Structure of the Swiss Occupational Therapy Workforce. A Survey Study / Anzahl und Struktur der Ergotherapie-Arbeitsplätze in der Schweiz: eine Online-Befragung
Authors: Ballmer Thomas , Kühne Nicolas , Petrig Andrea , Eggenberger Brigitte , Moioli Stefania , Gantschnig Brigitte E.
Published: November 2023

Background

As in other health professions, there is a shortage of skilled labour in the field of occupational therapy in Switzerland. To plan and implement effective measures to counter this shortage, empirical data on the size and structure of the Swiss occupational therapy workforce are needed.

Method

We conducted an online survey aimed at employers of occupational therapists, team leaders and self-employed occupational therapists in Switzerland. We collected data on the size and structure of the workforce in terms of sociodemographic characteristics, regional distribution, areas of work, and related topics. To analyse quantitative data, we used descriptive statistics and regression analysis. Qualitative data were narratively described.

Results

We collected data from 968 respondents pertaining to 3,022 Swiss occupational therapists, with a response rate of 73.6% for medical institutions and 58.2% for occupational therapists in private practice. Women make up 90.1% of the Swiss occupational therapy workforce. Swiss occupational therapists most often work with clients who have difficulties in connection with injuries or illnesses of the upper limbs, neurological illnesses or injuries, or challenges with mental health. The ratio of occupational therapists per 10,000 inhabitants in Switzerland is at least 3.2. Swiss occupational therapy provision is least dense in Central Switzerland. The average reported turnover rate among occupational therapy teams was calculated to be 20% (SD=27.9).

Conclusion

The results illustrate the persistent lack of gender diversity in the profession. They also show some disparities in geographical distribution and area of practice, which will be analysed in more detail in subsequent publications.
First report of barley root-knot nematode, Meloidogyne naasi from turfgrass in Idaho, with multigene molecular characterization
Authors: Skantar Andrea M. , Handoo Zafar A. , Kantor Mihail R. , Hult Maria N.
Published: November 2023

Barley root-knot nematode, Meloidogyne naasi Franklin, 1965, is one of the most important pest nematodes infecting monocots (Franklin, 1965). Two-inch core soil samples collected from a golf course in Ada County, Idaho were submitted for identification in November of 2019. A high number of Meloidogyne sp. juveniles were recovered from both soil samples using sieving and decantation followed by the sugar centrifugal flotation method. They were examined by light microscopy, morphometric measurements, and multiple molecular markers, including the ribosomal 28S D2–D3 and intergenic spacer 2 (IGS-2) regions, mitochondrial markers cytochrome oxidase I (COI) and the interval from COII to 16S, and the protein-coding gene Hsp90. Morphometrics as well as BlastN comparisons with other root-knot nematode sequences from GenBank were consistent with identification as M. naasi. Phylogenetic trees inferred from 28S, IGS-2, COI, or Hsp90 alignments each separated the Idaho population into a strongly supported clade with other populations of M. naasi, while the COII-16S interval could not resolve M. naasi from M. minor. This report represents the first morphological and molecular characterization of Meloidogyne naasi from turfgrass in Idaho.

Published: November 2023

This article reflects on the current context of social and health vulnerability, which has become a central issue in government agendas at all levels. They represent social, economic, environmental and health processes that generate a mixed exposure of the territory and the people who inhabit it, making some more vulnerable than others; on the other hand, these conditions are also reflected in the response capacity of each individual, household and society. The objective of this research is to determine the social vulnerability in health in the Mexican South Pacific region, using the official data from the Population and Housing Census of 2020, disaggregated at the municipal level. The variables or socio-spatial conditioning factors of health have been selected, which have been standardized using an omega index to obtain a synthesis indicator of all the variables used, applying a multivariate analysis technique called Spatial Classification Scores (SCS). It allows carrying out an integration of the variables used in a systematic way, which allows a better evaluation and understanding to identify areas with greater or lesser vulnerability. The Mexican South Pacific region is a territory of great diversity and complexity, both in the social as well as in the economic and geographical context, which is why at the national level is the region with the greatest social backwardness and with the worst health rates. The results show that the highest vulnerability values are located in Cochoapa el Grande, Metlatónoc (Guerrero) and San Simón Zahuatlán (Oaxaca), characterized by high deficiencies in health services, education, decent housing and employment.
The Demographic Transition: Analysis of Nuptiality Component on Change of Fertility in Rwanda
Authors: Gatera Etienne
Published: November 2023

This study is an assessment of the impact of the nuptiality component on the change in the fertility process, which is part of the demographic transition in Rwanda. It focusses on indicators such as age of first marriage, rates of divorce, separation, marriage dissolution, widowhood, polygamy, and number of unmarried people, for their impact on the change in total fertility rate (TFR) in Rwanda. Further, the study examines nuptiality level and behaviour in Rwanda. It is based on the investigation and interpretation of data from various reports of the National Institute Statistics of Rwanda (NISR) and the World Bank (WB), as well as data from experiments conducted by the researcher. The study concluded that, according to most of the reports, these indicators of nuptiality did contribute to the change of TFR during the demographic transition in Rwanda. Further, it recommended that the public statistical institution (NISR) should conduct a study on homosexuality and its impact on TFR in Rwanda. This study consists of four sections: section 1 - introduction; section 2 - literature review; section 3 - data and methods; section 4 - analytical methods, results and conclusion.

Muster der Theorie-Praxis-Integration in der hochschulgebundenen Journalist:innenausbildung in Deutschland
Authors: Franze Marcel , Ollrog Marc-Christian
Published: November 2023

Wie theoretisches Wissen und praktische Fähigkeiten verschränkt werden sollen, ist eine elementare Frage der hochschulgebundenen Journalist:innenausbildung. Die Integration der beiden Dimensionen wird als entscheidendes Bildungs- und Ausbildungsversprechen gesehen (Bergmann & Pörksen, 2007, S. 18). Diese Studie spürt einem empirisch fundierten Muster der Theorie-Praxis-Integration in der deutschen hochschulgebundenen Journalist:innenausbildung nach. Dabei sind unter Mustern Regelmäßigkeiten bzw. regelmäßig auftretende Strukturen oder Strukturmerkmale zu verstehen, die so oder ähnlich auch in anderen Reihen auftreten. Durch eine qualitative Inhaltsanalyse von zehn Modulhandbüchern deutscher Journalismus- und Journalistikstudiengänge und Leitfadeninterviews mit Studiengangleiter:innen und Professor:innen konnte ein Muster herausgearbeitet werden. Als Fixpunkt im Muster hat sich Projektarbeit herauskristallisiert. Die Lehrredaktion bleibt der Evergreen in den Curricula deutscher Journalistik- und Journalismusstudiengänge. Neben den Projekten ist sie der Ort bzw. Rahmen, der als am förderlichsten für die Integration erachtet wird.
Zwischen guten Absichten und ausbleibendem Erfolg. Ambivalenzen in der Online-Berichterstattung deutscher Tageszeitungen über die UN-Friedensmission MINUSMA
Authors: Reinbold Judith
Published: November 2023

Der Beitrag untersucht am Beispiel der Online-Berichterstattung zweier deutscher Tageszeitungen das journalistische Framing der Friedensmission MINUSMA. Grundlage ist ein 148 Berichte umfassendes Sample, in dem mithilfe einer qualitativ-induktiven, multimodalen Framing-Analyse vier verschiedene Frames beschrieben werden konnten: Verantwortung, Konflikt, Heldentat und Sicherheitsrisiko. Diese Frames beleuchten den Einsatz aus eher politischer oder militärischer Perspektive und lenken den Fokus dabei entweder verstärkt auf positive oder negative Aspekte. Im Zentrum dieses Beitrags steht die Frage inwiefern ambivalente Perspektiven auf die Beteiligung des Bundeswehreinsatzes in drei unterschiedlichen Zeiträumen – der Entscheidung für ein erweitertes Mandat, der fortschreitenden Einsatzdauer und dem Beschluss, das Mandat vorzeitig zu beenden – aufgegriffen werden. Die Analyse zeigt, dass während des politischen Entscheidungsfindungsprozesses kontroverse Standpunkte tendenziell eher reflektiert werden als nach der Entscheidungsfindung: So wurde MINUSMA nach der Mandatierung 2015 vorwiegend positiv geframed, nach dem Beschluss eines vorzeitigen Abzugs (Mitte 2023) allerdings deutet bislang vieles auf ein vorwiegend negatives Framing hin.
Seguridad humana y Acción Unificada del Estado en Colombia
Authors: Rivera-Páez Samuel , Acevedo-Navas Christian , Álvarez-Calderón Carlos Enrique
Published: November 2023

La seguridad humana se constituyó en un paradigma de la seguridad cuando en 1994, la Organización de las Naciones Unidas, con su informe de desarrollo humano, propuso cambiar el objetivo de la seguridad nacional de la supervivencia del Estado a la consolidación de la seguridad del ser humano como ciudadano. Por su parte, desde los años 1980, la Acción Unificada del Estado ha sido concebida por las Fuerzas Militares colombianas como el mecanismo del Estado en su conjunto, para garantizar sincronizadamente la construcción del Estado social de derecho, la legitimidad democrática y la seguridad en todas sus dimensiones. Este capítulo examina dicho mecanismo en diálogo con la seguridad humana, buscando describirlos e identificar factores de éxito que permiten inferir que la Acción Unificada del Estado puede ser una pieza fundamental de la seguridad humana por desarrollar en Colombia para conseguir lo que se ha denominado la paz total.
Alimento como bien fundamental. Implicaciones para la seguridad alimentaria en Colombia
Authors: Suárez-Calderón Jesús Leonardo
Published: November 2023

El presente capítulo describe, desde un enfoque cualitativo, el alcance del Estado en la seguridad alimentaria, según se considere el alimento como bien fundamental. Para esto, se caracterizó el alimento en cuatro dimensiones: biológica, por ser esencial para la vida humana; económica, en cuanto a su comercialización como materia prima o proce-sada; social, al ser determinante de culturas; y jurídica, como derecho humano. A partir de esto, se identificaron las implicaciones para el Estado colombiano, mediante el análisis de las políticas públicas desde la promulgación de la Constitución Política de Colombia de 1991, en torno de la conceptualización de las dimensiones. Finalmente, el análisis permitió identificar los desafíos para la implementación del derecho humano a la alimentación en Colombia, en correspondencia con la política de seguridad humana.
On receiving the witness
Authors: Martin Timothy
Published: November 2023

At this year’s conference, I was privileged to participate as one of the keynote speakers. Drawing on my dissertation, I gave a lecture on the pedagogical work and archival practices of an event known as The Toronto Homeless Memorial. This brief reflection is inspired by the way in which my words were received by conference attendees—and, more broadly, the work of listening to those who bear witness to violence. I, along with many others, relate to the memorial on a personal level; my research is a practice of witnessing and of partnering with the testimony of the memorial organizers. Influenced by Ann Chinnery’s (2013) thinking, I conceptualize the work of storylistening as facilitating cross-temporal relationality with the past—specifically, with past-others rendered silent and invisible. By receiving the testimony of the witness, we make possible moments of interruption and encounter for/with those abjected from public regard.

Coffee is a drink that is very popular with the people of Indonesia and in other countries. Coffee has many benefits but on the other hand, coffee can also damage health, the dangerous content in coffee is caffeine and cafeeic acid. The effect of coffee consumption is still a matter of controversy, one of which is the effect on the kidneys because the kidneys are the main excretory organ for removing metabolic waste from the body. The kidney is the second organ after the liver, which is most often the target of damage by chemicals. This study aims to determine the effect of multilevel doses of white coffee on the histological picture of rats' kidneys. This research is a completely randomized design study with four 4 treatments and four 4 replications. Consists of K (distilled water), P1 (0.36 ml), P2 (1.08 ml) and P3 (2.16 ml). The results of this study showed that macroscopic observations of the administration of white coffee civet coffee solution with different doses showed that the kidneys looked normal. It is characterized by the shape of the kidney like a pea and brownish-red in color. The P0 group was significantly different from the P1, P2, P3 groups. The P1 group was significantly different from the P0 group and the P2 group, P3. The P2 group was significantly different from the P0, P1, and P2 groups. The P3 group was significantly different from the P0, P1, and P2 groups. This study concluded that white coffee in multilevel doses affects the histopathology of kidneys in rats.

Günümüzde değişen çevresel faktörlere ve piyasa dinamiklerine ayak uydurmak için işletmelerde yenilikçi yaklaşımlarla ticari yaklaşımların dengelenmesi gerekmektedir. “Örgütsel çiftyönlülük” kavramına işaret eden bu dengelenme ihtiyacı, bazen kurumlarda yaşanan yapısal değişiklikler süresince belli bir “bağlam” olarak da adlandırılabilecek bir vizyon ve strateji planı çerçevesinde meydana gelmektedir. Sadece işletmeler değil, belli bir stratejik yönetim planına ve gelir-gider dengesine sahip olan kamu kurumu gibi kurumlar da bu durumu yaşamaktadır. Liderliğin rolünün ayrıca önem taşıdığı bu değişim dönemlerinde kilit öneme sahip olan “bağlam” – vizyon - dönüşümcü liderliğin karakteristik yapıtaşlarından birini oluşturmaktadır. Buradan hareketle bu araştırma, kalıcı yapısal değişikliklerde dönüşümcü liderliğin örgütsel çiftyönlülüğe etkisini stratejik bir vizyon ve gelir-gider dengesine sahip bir kamu kurumu olan Mersin Yenişehir Belediyesi’nde yapılan bir uygulamaya dayanarak ele almaktadır. Ekim 2023’te 296 belediye çalışanına uygulanan bir anket aracılığıyla gerçekleştirilen bu araştırma, dönüşümcü liderliğin ve yapısal değişiklikleri ilgilendiren unsurların bağlamsal çiftyönlülüğün sağlanması amacıyla söz konusu vizyonun aktarımında bir kamu kurumunda hangi dinamiklere bağlı olarak kurumsal işleyişi şekillendirdiğini ve dönüşümcü liderliğin bu süreçteki rolünü ortaya koymaktadır.

One of the main areas of scientific support for work in the field of ensuring radiation safety during the liquidation of nuclear legacy is the assessment of radiation effects among personnel of nuclear industry enterprises and the most significant radiogenic risks among workers of these enterprises. Objective. To conduct a retrospective analysis of ocular surface morbidity among personnel of a nuclear energy facility under long-term man-made external irradiation. Materials and methods. A retrospective analysis of ocular surface morbidity among personnel of a nuclear energy facility (NUF) under long-term man-made external irradiation was carried out, taking into account the absorbed dose equivalent. The medical records of 3,795 employees were analyzed, divided into 2 groups: main - medical records of 2,546 employees of the main production; comparison - medical records of 1249 employees of auxiliary production. Results. According to the results of a retrospective analysis, blepharoconjunctivitis, inflammation of the lacrimal drainage apparatus, and inflammatory lesions of the cornea are the most common among OAE personnel. At the same time, there is a statistically significant increase in the pathology of the ocular surface as the dose load increases among personnel of both the main and auxiliary production facilities of nuclear power plants. Conclusion. Among nuclear facility personnel exposed to long-term technogenic exposure to ionizing radiation, there is a statistically significant increase in the number of cases of ocular surface diseases as the dose load of soft tissues increases.

Purpose. Optimization of treatment of chronic conjunctivitis in the Southern Aral Sea region. Material and Methods. The research included 62 patients (120 eyes) with chronic conjunctivitis, aged 35–62 years, who had been observed in a polyclinic for the last 3 years, with signs of DES. All studied patients were divided into 2 groups by random sampling after preliminary adequate antibacterial and anti-inflammatory therapy; The control group (20 patients, 40 eyes) was instilled with an antiseptic - Tsinosol (composition: zinc sulphate, boric acid, Aseptic), 2 drops 3 times a day, for 30 days. In the main group (40 patients, 80 eyes), patients were instilled with an antiseptic - Tsinosol (2 drops 3 times a day) and an artificial tear (AT) medicine - Keratrop (composition: sodium carmellose, glycerin, levocarnitine, erythrolfirma Aseptica), 2 drops 3 times a day for a month. All patients underwent standard ophthalmological tests, and special studies were carried out to verify DES, including tests by Schirmer, Norn, Jones, the height of the lower lacrimal meniscus and the severity of the conjunctival fold were determined. Results. Studies have shown that in the main group, both subjective and objective signs of the disease significantly decreased compared with the baseline and with the data of the control group, and a significant improvement in the stability of the tear film was noted. Conclusion. To optimize the therapy of secondary DES, it is necessary to include in the treatment regimen AT medicines in general and the domestic medicine Keratrop in particular, as the medicine of choice in this region.

Published: November 2023

The article presents reference publications about the regions of modern Russia, addressed to children and youth audience. This topic becomes especially relevant in a complex geopolitical situation, when it is necessary to involve the younger generation in studying the history of not only the country as a whole, but also of their small homeland. That is why the article reveals some peculiarities of preparing and publishing such literature. For the first time the term “local history reference books for children and youth” (regional encyclopedias, reference books, guides for children) is proposed, the dynamics of publication by years and regions is traced. The value of such editions in both informational and patriotic aspects is revealed. The problem of low activity of book publishing in this area is raised. The bibliographic list of local history reference books for children and youth, published in the Russian Federation in 1992—2023, identified at the moment of writing, is presented for the first time.

Furfural is a pivotal renewable platform molecule obtained from the chemical breakdown of cellulose. While it has traditionally been valorized to value-added chemicals through catalytic hydrogenation in biorefineries, its direct electrocatalytic hydrogenation presents attractive advantages. This article describes the significant improvements brought by the structuring of copper cathodes applied to this process, in terms of activity and selectivity. We show that structured electrodes are capable of converting furfural to furfuryl alcohol with 100% selectivity at potentials as high as - 0.2 vs. the reversible hydrogen electrode (RHE) in neutral conditions (pH 7.0). Moreover, the same electrode can selectively generate either furfuryl alcohol or 2-methylfuran in acidic conditions (pH 1.0), depending on applied potential and temperature. We further show the existence of optimal voltage-temperature conditions for the efficient conversion of furfural to furfuryl alcohol or 2-methylfuran, highlighting the delicate influence of operating conditions on the selectivity of furfural reduction, in competition with the hydrogen evolution reaction in aqueous electrolytes. These performances are attributed to the resilience of Cu (I) species under operating conditions and their likely contribution to the electrocatalytic active site, as revealed by quasi-in-situ photoelectron spectroscopy.

Efficient predictive tools for oxygen evolution reaction (OER) activity assessment are vital for rational design of anodes for green hydrogen production. Reaction mechanism prediction represents an important pre-requisite for such catalyst design. Even then, lattice oxygen evolution remains understudied and without reliable prediction methods. We propose a computational screening approach using density functional theory to evaluate the lattice oxygen evolution tendency in candidate surfaces. The method is based on a systematic assessment of the adsorption energies of oxygen evolution intermediates on model active sites with varying local structure. The power of the model is shown on model rutile (110) oriented surfaces of a) RuO2, b) Ru(1−x)Ni(x)O2 and c) Ru(1−x)Ti(x)O2. The model predicts a) no lattice exchange, b) lattice exchange at elevated electrode potentials and c) minor lattice exchange at elevated electrode potentials and high titanium content. While in the case of a) and b) the predictions provide sufficiently accurate agreement with experimental data, c) experimentally deviates from the above prediction by expressing a high tendency to evolve lattice oxygen at high titanium content (x = 0.20). This discrepancy can likely be attributed to the presence of structural defects in the prepared material, which are hard to accurately model with the applied methodology.
