Published: February 2024

Members of the serine–arginine protein kinase (SRPK) family, SRPK1 and SRPK2, phosphorylate the hepatitis B core protein (Cp) and are crucial for pregenomic RNA encapsidation during viral nucleocapsid assembly. Among them, SRPK2 exhibits higher kinase activity toward Cp. In this study, we identified Cp sites that are phosphorylated by SRPK2 and demonstrated that the kinase utilizes an SRPK-specific docking groove to interact with and regulate the phosphorylation of the C-terminal arginine rich domain of Cp. We determined that direct interaction between the docking groove of SRPK2 and unphosphorylated Cp inhibited premature viral capsid assembly in vitro, whereas the phosphorylation of the viral protein reactivated the process. Pull-down assays together with the new cryo-electron microscopy structure of the HBV capsid in complex with SRPK2 revealed that the kinases decorate the surface of the viral capsid by interacting with the C-terminal domain of Cp, underscoring the importance of the docking interaction in regulating capsid assembly and pregenome packaging. Moreover, SRPK2-knockout in HepG2 cells suppressed Cp phosphorylation, indicating that SRPK2 is an important cellular kinase for HBV life cycle.

Published: February 2024

The article is devoted to the analysis of the development of housing construction in modern conditions and its impact on socio-economic development. The reasons are identified that contribute to a decrease in the dynamics of the commissioning of residential buildings, in particular, a slowdown in the use of mortgage lending, geopolitical changes, an increase in the key interest rate by the central bank, a reduction in the provision of preferential loans in the budget housing segment and an increase in rates for them, rising housing prices. The authors substantiate that during the prolongation of the development program, support for housing construction for the next period, it should be based on the current principles given in the work. The key negative features of the current model of housing construction development are highlighted. It is concluded that a well-built, well-developed system of housing construction development is able to solve acute issues of improving the living conditions of citizens and contribute to the provision of housing for those in need, to maintain the attractiveness of investing money in this industry, both from developers and investors, to ensure the preservation of cultural and historical, architectural features of territory planning, ensure the housing construction industry an effective state under the influence of external and internal influences and, in general, contribute to the sustainable socio-economic development of the regions.

Published: February 2024

The study examines the impact of caffeine consumption during prepubertal development and recovery on the contractile function of the adult corpus cavernosum in Wistar rats. Prepubertal male rats consumed distilled water (vehicle) and caffeine (5 mg/kg). A third group consumed caffeine and was allowed a period of recovery. Cavernosa tissues were excised at adulthood, and their contractile functions in the presence of Ca2+, K+, indomethacin, glibenclamide, methyl blue, L-NAME, and sodium nitroprusside were assessed. K+-induced increase in contraction in the caffeine-treated group was similar to that in the recovery group. Ca2+ ions, however, increased contraction significantly in the caffeine group compared to the recovery group. Acetylcholine-mediated relaxation (%) was significantly higher in the recovery compared to the caffeine treated after incubation with indomethacin and methyl blue. Acetylcholine-mediated relaxation, however, was higher in caffeine as compared to the recovery group after incubation with glibenclamide and L-NAME. Relaxation in the presence of sodium nitroprusside was significantly reduced in recovery than in the caffeine-treated group. Prepubertal caffeine intake had an erectogenic effect on the cavernous tissues in the presence of glibenclamide, nifedipine, and L-NAME. Inhibitors of prostacyclin (indomethacin) and cGMP (methyl blue) militate caffeine-induced relaxation. Effects were reversed after recovery.
Terahertz MIMO antenna array for future generation of wireless applications
Authors: Pant Rashmi , Malviya Leeladhar
Published: February 2024

The paper proposes a high gain, low ECC, and high isolation THz MIMO antenna array for future generation wireless applications to accommodate a growing population of mobile users. A THz MIMO antenna array is designed with dimensions of 1200 × 2200 × 191.29 µm3. It employs the array of double-slit complementary split-ring resonators (D-CSRRs) on the bottom layer to improve the gain, return loss, and isolation. The gain of the proposed antenna array is 11.3 dBi with 66.45 % radiating efficiency at 0.65 THz. The −10 dB impedance bandwidth lies from 0.62–0.66 THz. The parameters of the MIMO antenna are evaluated such as isolation, envelope correlation coefficient (ECC), diversity gain (DG), and channel capacity loss. The ECC and DG value observed are 2.84 × 10−6and 9.98 dB, respectively, at 0.65 THz. The channel capacity loss and isolation of the proposed MIMO antenna array are below 0.4 bps/Hz and (|S21| > 25 dB), respectively, in the complete operating band. The suggested THz MIMO antenna array can be utilised for THz high-speed wireless communication, video-rate imaging systems, sensing, the medical field for cancer imaging, security scanning, and the detection of illicit goods.

Published: February 2024

Background

N6-methyladenosine (m6A) is the most frequently occurring interior modification in eukaryotic messenger RNA (mRNA), and abnormal mRNA modifications can affect many biological processes. However, m6A’s effect on the metabolism of antiplatelet drugs for the prevention of ischemic stroke (IS) remains largely unclear.

Methods

We analyzed the m6A enzymes and m6A methylation in peripheral blood samples of IS patients with/without clopidogrel resistance (CR), and the peripheral blood and liver of rat models with/without CR. We also compared the effect of m6A methylation on the expression of the drug-metabolizing enzymes (CYP2C19 and CYP2C6v1) in CR and non-CR samples.

Results

Methyltransferase-like 3 (METTL3), an m6A enzyme, was highly expressed in the peripheral blood of patients with CR, and in both the peripheral blood and liver of rats with CR. This enzyme targets CYP2C19 or CYP2C6v1 mRNA through m6A methylation, resulting in low expression of CYP2C19 or CYP2C6v1 mRNA. Consequently, this leads to decreased clopidogrel metabolism and CR.

Conclusion

The METTL3-mediated methylation of CYP2C19 mRNA may aggravate CR in IS patients.
Der Supermarkt als pandemischer Raum: Affektive Ansteckung in der Corona-Krise
Authors: Hoppe Katharina , Meier Lars , Richterich Nils , Wratschko Lukas
Published: February 2024

Der Artikel geht Rekonfigurationen des Supermarkts als zentralem (halb-)öffentlichen Bezugspunkt der Alltagspraxis im Zuge der Maßnahmen zur Eindämmung der Verbreitung des Corona-Virus im Frühjahr 2020 nach. Das Hereinbrechen der Pandemie hat öffentliche Räume nicht nur aufgrund der permanenten Konfrontation mit dem Ansteckungsrisiko mit dem Virus verändert, sondern auch affektive Ansteckungsdynamiken freigesetzt, die im Raum des Supermarktes besonderen Niederschlag fanden. Im Anschluss an die Arbeiten Gabriel Tardes untersucht der Artikel mit einer Heuristik der Ansteckung leitfadengestützte Interviews und arbeitet heraus, in welchen Weisen der Supermarkt nicht nur durch Covid-19, sondern auch durch sozial konstituierende und zirkulierende Affekte zu einem pandemischen Raum wurde. Die Atmosphäre des Supermarkts als intensivem, pandemischem Raum charakterisiert der Artikel als ‚unheimlich‘ und geprägt von Angespanntheit, gesteigerter sozialer Kontrolle und Gefühlen des Eingeschlossenseins. In einem Ausblick geben wir zu bedenken, dass das Ansteckungsgeschehen mit sozialen Ungleichheiten verwoben ist, was sich mit dem Konzept der affektiven Disposition weiter bestimmen ließe.
Prilozi za povijest dokumentalistike i informacijske znanosti
Authors: Aparac-Jelušić Tatjana
Published: February 2024

Cilj. U ovom se članku nastoji pregledno i kritički prikazati razvoj dokumentalistike i informacijske znanosti u zemljama njemačkog govornog područja. Budući da do sada, osim na njemačkom jeziku, nije napisan cjelovit pregled o tome kako se razvijala dokumentalistika i kakav je bio njezin odnos prema knjižničarstvu te kako je i kada došlo do promjene paradigme prema informacijskoj znanosti, hrvatskim su stručnjacima takva saznanja uskraćena.
Pristup/metodologija. Rad se temelji na kritičkom iščitavanju i interpretaciji objavljene literature, poglavito članaka, izvještaja i prikaza iz časopisa Nachrichten für Dokumentation (od 1990: Nachrichten für Informationswissenschaft), nekoliko drugih njemačkih časopisa i knjiga te proučenih svih sedam izdanja poznatog priručnika Grundlagen für Dokumentation (kasnije: Grundlagen für Informationswissenschaft).
Rezultati. Pregledno je izložen razvojni put njemačke, austrijske i švicarske dokumentalistike i informacijske znanosti, ukazano je na probleme i dvojbe s kojima su se stručnjaci iz tih sredina susretali, kao i na nesigurnost oko definiranja novog polja. Rad obilježava i osvrt autorice na nedostatnu argumentaciju razloga koji su doveli do napuštanja izvorno njemačke dokumentalističke paradigme u prilog preuzimanja paradigmi koje su zagovarali stručnjaci iz angloameričke sredine.
Ograničenja. Kako je ovaj rad zamišljen kao dio niza o razvoju dokumentalistike i informacijske znanosti u nekoliko utjecajnih sredina (američko-britanskoj, frankofonskoj, germanskoj, ruskoj, odnosno u zemljama bivšeg Sovjetskog Saveza) te utjecaja modela i trendova iz tih sredina na razvoj dokumentalistike i informacijske/ih znanosti na području bivše Jugoslavije, s naglaskom na Hrvatsku, za očekivati je da će do objave ostalih pregleda možda ostati nedovoljno jasne pojedinosti problematizirane u ovom članku.
Društveni značaj. U Republici Hrvatskoj prihvaćene su informacijske znanosti kao akademska i znanstvena disciplina 1983. godine, pa je to potaknulo istraživačku znatiželju oko utvrđivanja najranijih izvora spoznaja o razvojnim trendovima u drugoj polovici 20. stoljeća. Ovim istraživanjem pridonosi se razumijevanju okolnosti izrastanja informacijske/ih znanosti kao mladog znanstvenog polja.
Originalnost/vrijednost. Istraživanje je provedeno na izvornim materijalima na njemačkom jeziku, a obogaćeno je komentarima i saznanjima autorice koja prati ovo područje od njegova službenog prihvaćanja u hrvatsku akademsku i znanstvenu obitelj do današnjih dana.
ЗИМОВІ ЛИЖНІ ПОХОДИ КАРПАТАМИ, ПРИСВЯЧЕНІ ДІЯЛЬНОСТІ СХІДНОПОЛЬСЬКОГО ЛЕГІОНУ
Authors: Мицкан Богдан , Zaborniak Stanislaw , Мицкан Тетяна , Маланюк Тарас
Published: February 2024

Мета. Розкрити складові організації і проведення зимових лижних походів Карпатами  в 1934-1939 рр., присвячених діяльності  другої бригади Східнопольського легіону. Методи. Джерельною базою дослідження були: Національний цифровий архів Польщі; архів Військового географічного інституту Польщі, а також  архівні матеріали міст  Львова та Івано-Франківська. Результати. З метою започаткування проведення лижних походів Карпатами по місцях боїв та поховань польських легіонерів 16 грудня 1933 р. Товариство друзів Гуцульщини провело установчу нараду за головуванням генерала Тадеуша Каспшицького, тодішнього заступника міністра військових справ в уряді Другої Польської Республіки і прийняло ухвалу щодо проведення  у 1934 році цього першого спортивно-військового заходу, який передбачав проходження на лижах дистанції довжиною 83 км з трьома етапами (перший - 21 км від с. Березов (Тячівський район, Закарпатська область) до Пантирського перевалу; другий - 32 км від Рафайлова (з 1946 року село Бистриця, Надвірнянського району, Івано-Франківської області) через Довжинець та Шумерську долину до Татарського перевалу; третій – 30 км від урочища Лаби до Ворохти) зі стрільбою на заключній ділянці дистанції.    В наступні роки (1935-1939) було проведено ще чотири лижні походи Східними Карпатами за участю як команд польських військових і поліції, так і місцевого населення (гуцулів). Перепад висот на маршруті сягав понад 600 м. Проведення зимових лижних походів мало на меті не тільки спортивні цілі, але також виконувало соціально-політичні функції, спрямовані на інтеграцію населення Східних Карпат з польською державністю, покращення його економічного становища (наприклад, завдяки орендованому житлу, їжі або можливості продажу своїх ремесел). Події, що супроводжували ці походи включали, серед іншого, Чорногірський лижний кубок польського туристичного товариства за участю іноземних команд (Чехословаччини, Румунії). Про важливу роль цих спортивно-військових заходів  у 1934–1939 роках, свідчить присутність на них численних учасників (понад 160 осіб) та значних особистостей, зокрема воєвод та генералів, керівників Товариства друзів Гуцульщини, Польської лижної асоціації та Польського туристичного товариства. Висновок. Отже, за період 1934-1939рр. було проведено шість лижних походів під особливим патронатом  Війська Польського та за участю Польської лижної асоціації, Польського товариства Татр, Товариства друзів Гуцульщини, Державного управління фізичної та військової підготовки, а також парамілітарних організацій «Стрілецька спілка», гімнастичного товариства «Сокіл».

The mechanism of the shrinkage of paper has been investigated microscopically and this has resulted in a better understanding of the structure of paper. It is shown that the shrinkage of paper gives rise to a `microstructure’, in terms of which Theological and other properties of paper, as well as the influence of papermaking variables upon them, can be explained. Although the theory is considered to be comprehensive, it has not been possible to develop it completely in this initial publication.

Advice to Clinicians From Expectant Parents at Extreme Prematurity: A Multimethod Study
Authors: Sullivan Anne , Arzuaga Bonnie , Luff Donna , Ward Erin , Williams David N. , Cummings Christy
Published: February 2024

BACKGROUND AND OBJECTIVES

Despite recommendations for patient-centered counseling on extreme prematurity, clinicians often miss opportunities to communicate in a way that facilitates parental knowledge, decision-making, and emotional support. In this study, we aimed to determine empirical, parent-derived recommendations and advice for clinicians counseling on extreme prematurity.

METHODS

Pregnant women (and their partners) admitted at 22 0/7 to 25 6/7 weeks’ estimated gestation participated in postantenatal counseling semi-structured interviews or questionnaires to explore parental preferences in the counseling process, including advice to clinicians. Thematic analysis was performed.

RESULTS

A total of 39 interviews and 47 questionnaires, representing 62 total prenatal consultations, were completed. Thematic analysis of participants’ advice to clinicians from both interview and questionnaire data resulted in 14 parent-derived recommendations to clinicians who counsel expectant parents at extreme prematurity. Parental recommendations related to compassionately engaging, supporting, and communicating with families, as well as aligning teams and following up.

CONCLUSIONS

We present an empirical parent-derived, family-centered, and practical approach for clinicians counseling on extreme prematurity. Future studies should include a more diverse patient population and assess the impact of these recommendations on the counseling process and outcomes.
Negative emotions mediate the association between the topology of the complex brain network and smartphone use disorder: A resting-state EEG study
Authors: Yin Yulong , Li Xu , Lau Joseph T. F. , Nan Sunian , Ouyang Mingkun , Cai Xiao , Wang Pengcheng
Published: February 2024

Background

Increasing research has examined the factors related to smartphone use disorder. However, limited research has explored its neural basis.

Aims

We aimed to examine the relationship between the topology of the resting-state electroencephalography (rs-EEG) brain network and smartphone use disorder using minimum spanning tree analysis. Furthermore, we examined how negative emotions mediate this relationship.

Methods

This study included 113 young, healthy adults (mean age = 20.87 years, 46.9% males).

Results

The results showed that the alpha- and delta-band kappas and delta-band leaf fraction were positively correlated with smartphone use disorder. In contrast, the alpha-band diameter was negatively correlated with smartphone use disorder. Negative emotions fully mediated the relationship between alpha-band kappa and alpha-band diameter and smartphone use disorder. Furthermore, negative emotions partially mediated the relationship between delta-band kappa and smartphone use disorder. The findings suggest that excessive scale-free alpha- and delta-band brain networks contribute to the emergence of smartphone use disorder. In addition, the findings also demonstrate that negative emotions and smartphone use disorder share the same neural basis. Negative emotions play a mediating role in the association between topological deviations and smartphone use disorder.

Discussion

To the best of our knowledge, this is the first study to examine the neural basis of smartphone use disorder from the perspective of the topology of the rs-EEG brain network. Therefore, neuromodulation may be a potential intervention for smartphone use disorder.
Startup success from the founder's perspective
Authors: Virágh Enikő Anna , Tímár Gigi , Pecze Krisztina
Published: February 2024

Subjective entrepreneurial success has emerged as an area of academic interest. However, no research study has yet been conducted on startup founders as a specific group of entrepreneurs. Although ‘success’ has been prominently covered in existing startup literature, studies predominantly focus on the possible reasons behind startup success, measuring it solely in economic terms. Drawing upon the qualitative analysis of 22 in-depth interviews with Hungarian startup founders, this paper aims to explore the complex structure of subjective startup success from the founder's perspective along with its gendered patterns. The five dimensions of subjective startup success emerging from the data are similar to those of subjective entrepreneurial success: firm performance, team, personal fulfilment, community impact and personal financial reward. Nevertheless, results reveal that there exists considerable difference between the substance of firm performance dimension in the subjective entrepreneurial success model and in our subjective startup success model. Further, it is found that the interplay among indicators of success could range from synergies to tensions. Finally, personal fulfilment is found to be the only dimension that reflects a marked gender difference in the sample.

This essay aims to determine the value of Islamic accounting in the contemporary world. The most famous examples of accounting fraud techniques are the Enron and Arthur Anderson scandals. Naturally, it is unlikely that this state of affairs will occur again in the future. The key elements of the Islamic accounting concept are explained in this essay. The descriptive qualitative research methodology used in this essay. And it can be concluded that despite the fact that many businesses are starting to transition to using Islamic principles, Islamic accounting still feels isolated in Muslim-dominated countries. Many people still believe that this is all a ruse because they have not fully implemented the concept of sharia. Sharia accountants understand the principles of the Islamic religion and will realize that if they engage in deviant behavior, they will not only be punished by their superiors but will also be held accountable for their behavior before Allah swt. As if it is still being debated, sharia accounting is important because everything is accounted for not only to superiors or management.

Abstract This study aims to examine arisan transactions in Indonesia from an economic perspective in general and an Islamic economic perspective in particular. Along with the development of times and culture, so do human needs. Man has been given freedom of worship, but with limited freedom. A wide variety of practices and transactions are evolving today to meet needs. One example of a practice that is commonly found in the community is social gathering. This type of research is qualitative research with a literature study approach. Data were obtained from articles and journals from pre-existing research. The results showed that arisan when viewed from its acquisition, there are two forms of arisan, namely arisan goods and arisan money. Based on an economic perspective, social gatherings can be a means of saving, helping business sustainability, and can also be used as a business strategy. Meanwhile, from an accounting perspective, arisan is interpreted as an investment activity with the motive of avoiding inflation. Islamic economics views arisan as a transaction that can be punished mubah (permissible) as long as it does not contain elements that do not contradict the principle of muamalah.

Authors: Durohman Hapid
Published: February 2024

This research aims to investigate the influence of religious commitment and self-efficacy as internal variables on the purchasing behavior of Halal cosmetics among the Millennial Generation in Indonesia. Additionally, the study examines the moderating role of Halal literacy in the relationships between behavior, subjective norms, perceived behavioral control, and intentions to purchase Halal cosmetics. The research employs a quantitative method with Structural Equation Modeling analysis using SmartPLS 4.0 software. The findings reveal that religious commitment and self-efficacy significantly influence the purchasing behavior of the Millennial Generation regarding Halal cosmetics, and normative beliefs significantly affect subjective norms. Furthermore, attitude and subjective norms exhibit a significant relationship with the intention to purchase Halal cosmetics, while perceived behavioral control does not show significance. Moreover, Halal literacy has a positive moderating effect on behavior and subjective norms concerning the purchase intention. However, halal literacy does not moderate the relationship between perceived behavioral control the purchase intention.

Published: February 2024

This study was carried out to investigate the current status of surface water and groundwater quality in Lower Seybouse and Annaba Plain, NE Algeria. 36 surface water and groundwater samples were collected in this area, and various physicochemical parameters were analysed. The quality of surface water and groundwater for drinking and the associated health risks were assessed using a Water Quality Index (WQI) and a Human Health Risk Assessment (HHRA) model. The results show that all samples are alkaline with the EC values ranging from 1139 to 5555 μS/cm. The ionic dominance pattern was in the order of Na+ > Mg2+ > Ca2+ > K+ for cations and Cl– > HCO3– > SO42 – > NO3– for anions, respectively. The dominant water types are SO4-Cl-Ca-Mg and SO4-Cl-Na, formed by dissolution of evaporative and carbonate-rich material. All samples are unsuitable for drinking, with 1 sample classified as poor (rank = 4) and 35 samples as extremely poor (rank = 5). These samples are mainly located near the Seybouse Wadi, which is a natural outlet for wastewater from human activities. The assessment of non-carcinogenic risk showed that the Hazard Index (HI) for males ranged from 0.12 to 1.01 with a mean of 0.30 and only one sample exceeded value 1. For females, the HI was between 0.16 and 1.28 for females, with a mean of 0.39. The risk for children was even higher, ranging from 0.41 to 3.28, with a mean of 1.03, suggesting that children are more vulnerable to water contamination. The Carcinogenic Risk (CR) values for Pb ranged from 10–3 to 8.6 · 10–3, with a mean of 2.6 · 10–3 for males, and between 1.4 · 10–3 to 10–2, with a mean of 3.3 · 10–3 for females, while for children the CR values ranged from 3.5 · 10–3 to 2.7 · 10–3, with a mean of 8.4 · 10–3, indicating that no possible CR from water drinking.

Published: February 2024

This study aimed to optimize the enzymatic extraction of polysaccharides from Mytilus coruscus using the response surface method, characterize its composition, and investigate its antitumor activity in vivo. Employing a three-level and four-variable Box–Behnken design and setting the Mytilus coruscus polysaccharides (MCP) extraction yield (%) as response value, the optimum enzymatic extraction conditions were as follows: extraction time was 173.34 min, extraction temperature was 56.82°C, extraction pH was 5.64, and the ratio of liquid to fresh flesh was 19.82. Under the optimized conditions, the predicted extraction yield indicated by the response surface methodology (RSM) model was 19.68%, which showed compliance to the experimental yield (19.53%). GC-MS was used to detect the monosaccharide composition and methylation analysis, it was showed that MCP was composed of Rhamnose, Arabia sugar, fructose, mannose, glucose, and galactose with a molar ratio of 1.92:1.29:8.18:27.90:27.63:29.50 and the main linkage type was 1→4 linked glucose, the molecular weight of the polysaccharide was about 57 kDa determined by high-performance gel permeation chromatography (HPGPC). The antitumor activity was investigated in mice. The tumor growth inhibitory rate, spleen index, and thymus index were calculated. The tumor inhibition rates of medium and high-dose MCP were 21.8% and 32.9%, respectively, which were significantly different with the model group. Spleen index and thymus index significantly increased in medium and high-dose MCP group. It was obvious that MCP could improve immunity and inhibit the growth of tumors.
The Discoverers of the Platinum Isotopes
Authors: Arblaster J. W.
Published: February 2024

The history of the discovery of the isotopes of platinum, made over some 61 years between 1935 and 1996, can be gleaned from the various editions of the monograph “Table of Isotopes” (–). However, except for a few cases, in general, little attempt has been made to correlate the circumstances of the discoveries of the isotopes of individual elements. In this article attention is drawn to the work of pioneering scientists who in a comparatively short period of creativity discovered the majority of the isotopes of platinum.
Molecular Design for Long-Range Electronic Communication between Metals
Authors: Hoshino Yoshimasa
Published: February 2024

To construct molecular devices it is necessary to use mixed-valence metal complexes which have a large metal-metal separation distance and which exhibit strong coupling between the metals, so that errors which might arise from electrostatic interaction between the metal ions are prevented. Bridges, or spacers, are needed between two metal terminal sites to operate as effective molecular wires when one metal terminal site is in the excited state, and/or when both the terminal components are in the ground state. Binuclear ruthenium complexes, consisting of tris(β-diketonato)ruthenium(III) units, which are suitable as the terminal redox sites, can be used to evaluate how well the bridges function as molecular wires in the ground state. This is because their Ru(III)-Ru(II) and Ru(IV)-Ru(III) mixed-valence states are accessible for experimental use. In this article, a polyyne system and an ethynylated aromatic system are evaluated as molecular wires, using the binuclear (β-diketonato)ruthenium(III) complexes containing these systems as the bridges. In the Ru(IV)-Ru(III) mixed-valence state, the ruthenium complexes show relatively strong electronic interactions between the metal centres. This is interpreted by a superexchange (through-bond) hole transfer mechanism via the highest occupied molecular orbitals of the bridge. Molecular orbital calculations provide a guide to the molecular design of bridging ligands for long-range electronic coupling.
Catalysis for Low Temperature Fuel Cells

Published: February 2024

In the first part of this three part paper, published in January 2002, we dealt with enhancing the performance of low temperature proton exchange membrane fuel Cells by improvements to the platinum-based cathode materials and to the cathode design. In this second part of the paper we shall discuss the improvements in the reformate (CO and CO2) tolerance at the anode and in extending the MEA durability. Improvements have been achieved by advances in platinum/ruthenium electrode design, in the application of bilayer anodes for durable air bleed operation, and in the addition of a water electrolysis electrocatalyst to the anode for Cell reversal tolerance. In the third part of the paper the particular challenges presented by the direct methanol fuel Cell will be discussed.
Cathodic Reactivity of Platinum and Palladium in Electrolytes in Superdry Conditions
Authors: Cougnon Charles , Simonet Jacques
Published: February 2024

Platinum and Palladium behave in an unexpected manner when cathodically polarised in the presence of electrolytes dissolved in carefully dried polar organic solvents, such as N,N-dimethylformamide. A reductive layer is formed on the metal the thickness of which depends on the amount of electricity consumed during the course of the electrolyses. Although this reaction seems to be of a general character with most of the common electrolytes, in this paper we will focus on results obtained with a large palette of tetraalkylammonium salts and alkali metal iodides.
Catalysis for Low Temperature Fuel Cells
Authors: Hogarth M. P. , Ralph T. R.
Published: February 2024

The direct methanol fuel Cell (DMFC) is a low temperature fuel cell operating at temperatures of 30 to 130°C. The DMFC is powered by a liquid fuel (usually considered essential for transport uses) and is therefore regarded by some as the ideal fuel cell system. In this paper, the DMFC is compared to the hydrogen-fuelled proton exchange membrane fuel Cell (PEMFC) which was discussed in detail in the January and July issues. While a typical DMFC is less efficient than a PEMFC, work to improve its performance with new electrocatalyst materials for utilisation in the membrane electrode assemblies has proved successful. This work is described here and some possible commercial uses for the DMFC are also considered.
