Authors: Andalas P. Mutiara
Published: April 2022

The orphanage management see urgent needs to include 'narrative competence' in staff formation for the more holistic service of the elderly. The elderly psychosocial needs require the availability of staff or support groups to hear the story of elderly life. Limitations of staff at Bethania, Lembean, North Minahasa nursing home to meet these needs provide space for support groups to fill this role temporarily. In addition to applying narrative skills in communication with the elderly, this community service becomes a privileged opportunity for the researcher who is an informal teacher in this field to deepen the 'narrative competence' of the elderly. Holistic service to the elderly in the context of the demographic revolution requires the organization of nursing homes to immediately organize sustainable formation for staff in 'narrative competence'.

The activities of community service which were conducted in Sukorejo, Girikerto, Turi, Sleman aimed to train farmers to be able to produce high quality goat milk, be skillful to process pasteurized milk, and be capable of marketing their dairy products. The activities consisted of counseling and training, focusing on the implementation of hygienic milking procedure and processing pasteurized milk. The community service was carried out in partnership with Plaza Agro, the Faculty of Animal Husbandry of Universitas Gadjah Mada, which is engaged in the sale of dairy and agricultural products. The training materials consisted of lactating goats, stage pens, goat milk, pasteurization and packaging equipment, and chemicals for milk quality testing. Counseling and discussion were done either during farmers meeting or between their activities in the communal goat houses. The program also carried out the procurement of equipment for milk processing and packaging which was facilitated by IbM Ristek Dikti (Higher Education) program 2016. Training results showed that an increase in the number of farmers who implemented hygienic milking, especially on the sanitation aspect, resulting in good quality milk. Density ranged from 1.030 to 1.034 in gravity, 5.5 to 5.6% of fat content and 15.3 to 15.5% of dry matter. The mild had a good flavor, odorless, and without alcohol. The quality of pasteurized milk was good, odorless, and had a typical goat's milk flavor. The reduction time of metylene blue reduction test was 7.9 hours, indicated that the approximate number of bacteria in milk approached 150000/mL, whose average of shelf life was 7 days. Initial marketing of pasteurized goat milk in Plaza Agro was limited on a small scale. The study concluded that processing pasteurized milk was useful for farmers to find an alternative market of goat milk.

Automation, Market Concentration, and the Labor Share
Authors:   University of Rochester, Firooz Hamid , Liu Zheng ,   Federal Reserve Bank of San Francisco, Wang Yajie ,   University of Rochester
Published: April 2022

Since the early 2000s, a rising share of production has been concentrated in a small number of superstar firms. We argue that the rise of automation technologies and the cross-sectional variation of robot use rates have contributed to the increases in industrial concentration. Motivated by empirical evidence, we build a general equilibrium model with heterogeneous firms, endogenous automation decisions, and variable markups. Firms choose between two types of technologies, one uses workers only and the other uses both workers and robots subject to an idiosyncratic fixed cost of robot operation. Larger firms are more profitable and are thus more likely to choose the automation technology. A decline in the cost of robot adoption increases the relative automation usage by large firms, raising their market share of sales. However, the employment share of large firms does not increase as much as the sales share because the expansion of large firms relies more on robots than on workers. Our calibrated model predicts a cross-sectional distribution of automation usage in line with firm-level data. The model also implies that a decline in automation costs reduces the labor income share and raises the average markup, both driven by between-firm reallocation, consistent with empirical evidence.
Determinant of Land Use Change in South Kalimantan: An Evidence from Banjarbaru City and Banjar Regency
Authors: Supriatna Supriatna , Hashilah Fathia , Mukhtar Mutia Kamalia , Wardani Kartika Kusuma
Published: April 2022

Environmental degradation, biodiversity loss, climate change, and other environmental catastrophe are negative impacts caused by irresponsible land use change. It is vital to investigate the driver of the land use change to avoid undesirable environmental catastrophes. On the other hand, determinants of the occurrence of the land use change are very complex to be identified. In the last few years, floods hit many parts of the world, one of them was a massive flood in South Kalimantan in the last few years. There is a presumption that this disaster is caused by land use changes inside the watershed. This paper aims to identify the determinants of the land use change in Banjarbaru City and Banjar Regency inside Martapura and Maluka Watershed. This study found out that having a secure land tenure per se does not incentivize landowners to prevent land use change. However, having a secure land tenure is a crucial factor in affecting land use change if the land they own is in large size. Having secure land tenure with large land size affects the occurrence of land use changes significantly by conducting agricultural and plantation extensification. This situation depicts that agricultural and plantation extensification exists in the rural area of South Kalimantan, which is triggered by economic profit orientation. Thus, the accumulation of secure land tenure and large land size need to be considered as land use change determinants for current and future’s land use policy in the context of Indonesia.
Social inequality and health: the historical and sociological study
Authors: Liadova A. V.
Published: April 2022

The article examines social determinants, which aﬀect health under the context of the spread of a new coronavirus infection. The author points out that the study of the impact of various factors on the health of society and individual has been quite widely represented in scientiﬁc research discourse. There are also diﬀerent classiﬁcations of them. However, in the current situation of a pandemic, this question is again actual because of the diﬀerences in the levels of morbidity and mortality among the population around the world. In this regard, based on the analysis of the main social determinants of health, the author deﬁnes the factors, which play a determining role in the spread of the new coronavirus infection. They are the following: the features of the organization and functioning of national health systems; the possibility of protecting and preventing health; the degree of social trust; the level of social solidarity; the degree of digital socialization, including the level of digital literacy; the level of health literacy of the population, national and cultural characteristics, which aﬀect a compliance, the perception of preventive measures, in particular, vaccination. According to the author, these factors include both objective and subjective characteristics. But, no less that under the conditions of such a phenomenon, how can one characterize the situation, the current system of a pandemic of a new coronavirus infection, the health of an individual and society turns into a phenomenon of social construction, the mechanism of which is based on factors of external inﬂuence.
Nonlinear social and cultural dynamics: P.A. Sorokin’s theory and contemporary approaches
Authors: Kravchenko S. A.
Published: April 2022

The article deals with the pioneering approaches of P.A. Sorokin to the study of non-linear transformations of social and cultural realities in the form of ﬂuctuations. They have complex causality of both deterministic and non-deterministic character, which the scientist formulates through principles: immanent generation of consequences, self-deﬁnition by the system of its own destiny and self-determination. On the basis of these methodological innovations, he “rediscovered” the progress as an exclusively bottom-up development and argued that the pragmatically oriented development of Truth and Beauty while diminishing the production of Good leads to non-linear deformations of the institutions of democracy, law, and the family. Today Sorokin’s ideas are being actualized because non-linear approaches to the interpretation of the global complexity are in demand. The theories of becoming (P. Sztompka), rhizomic development (J. Deleuze and F. Guattari), hybridization (J. Urry), metamorphization of the world (U. Beck) and traumatic development (P. Sztompka, J. Alexander, J.T. Toshchenko) are analyzed in detail. It is concluded that in the foreseeable future the humanity will have to live with the dominance of the non-linear realities. Accordingly, we need new scientiﬁc instruments for their governance, based on interdisciplinarity, which should have a humanistic core – that corresponds to the content and spirit of P. Sorokin’s theory.
Features of sociological analysis of religion in Russia during the imperial period of its history
Authors: Elishev S. O.
Published: April 2022

The article deals with the features of sociological analysis of religion in Russia during the imperial period of its history. The national sociological tradition of study of religion as a socio-cultural phenomenon and a social institution, which was developed during this period, had its own unique and peculiar appearance and was just begun to revive again in post-Soviet Russia, is sharply diﬀerent from the tradition that took place in the West. In this context, the appeal to the works of classics of Russian religious, socio-political thought, unfortunately undeservedly forgotten, is a very promising area of modern sociological research.

When studying this problem, the author emphasizes the study of the works of representatives of three ideological areas of Russian religious and socio-political thought: conservatism, liberalism and socialism, as well as the peculiarities of the historical development of Russian society and the state and those events that had a signiﬁcant impact on the formation and development of scientiﬁc understanding of religion in Russia. Among such features, the author, in particular, refers to the formation of an “antisystem” (systemic integrity of people who are negative about their homeland, hate their own nation, its values and culture, history, traditional religious, political and social systems) among the Russian intelligentsia, bureaucracy and part of the elite of Russian society, under a certain inﬂuence of Westernism, as a consequence of the spiritual schism of the 18th century, which occurred in the educated strata and elite of Russian society.

The author of the article analyzing the views of A.I. Herzen, P.L. Lavrov, M.A. Bakunin, P.A. Kropotkin, G.V. Plekhanov, V.I. Lenin, emphasizes the understanding of religious issues by representatives, primarily the socialist camp, who dreamed of carrying out a socialist revolution in Russia and who were extremely negative about religion, religious institutions and the traditional life of society. He notes the fact that the authors mentioned above were more concerned with introducing various ideological stamps into science, as well as using political technologies to discredit in a destructive way for society and the State, this traditionally important sphere of life for any society and an inﬂuential social institution. Against this background, a peculiar exception to the rules was the balanced, scientiﬁcally based approach to sociological analysis of religion in society developed by P.A. Sorokin, with an emphasis on the study of the integrating role of religion in social stratiﬁcation.
On (quasi-)morphic property of skew polynomial rings
Authors: DEHGHANI Najmeh
Published: April 2022

The main objective of this paper is to study (quasi-)morphic property of skew polynomial rings. Let $R$ be a ring, $\sigma$ be a ring homomorphism on $R$ and $n\geq 1$. We show that $R$ inherits the quasi-morphic property from $R[x;\sigma]/(x^{n+1})$.
It is also proved that the morphic property over $R[x;\sigma]/(x^{n+1})$ implies that $R$ is a regular ring. Moreover, we characterize a unit-regular ring $R$ via the morphic property of $R[x;\sigma]/(x^{n+1})$. We also investigate the relationship between strongly regular rings and centrally morphic rings. For instance, we show that for a domain $R$, $R[x;\sigma]/(x^{n+1})$ is (left) centrally morphic if and only if $R$ is a division ring and $\sigma(r)=u^{-1}ru$ for some $u\in R$. Examples which delimit and illustrate our results are provided.

Published: April 2022

Blood supply of bone tissue is one of the key factors in vital functions and reparative regeneration. The bloodstream supply nutrients and oxygen, remove toxic substances. Reparative regeneration is not impossible without the participation of the microvasculature of the bone tissue, mainly of the periosteum and feeding arterioles. Thus, the study of the microcirculation of bone tissue makes it possible to evaluate the physiological state of the bone tissue in normal and pathological conditions, as well as the dynamics of the consolidation of the bone fragments in fractures. Considering the morphological features of the bone tissue and its blood supply, there are certain obstacles in the study of microcirculation in real time and without surgery intervention. However, there are exist methods using near-infrared optical systems wich allow to realize a non-invasive examination of patients. This review discusses in detail the most well-known optical methods and also effective method of ultrasound dopplerography.

Published: April 2022

Introduction. In the last decade the pancreas surgery has undergone considerable development, connected with the introduction of modern interventional procedures for treatment tumors and acute pancreatitis. There are carried out active studies of the risks elimination while transplanting the pancreas, its success considerably depends on the surgeon’s knowledge of the variant anatomy of this organ.

The aim of this study is to show on corrosive preparations the main features of intraorganic arterial blood supply of the human pancreas body and tail.

Materials and methods. The investigation was made on 40 specimens of the human pancreas: 17 – corrosive preparations, 23 – fixed preparations of the pancreas with the parenchyma dissection. Pancreatic vessels were filled with latex of different colors to verify arteries and veins. The preparations were fixed in 10 % acid formalin for a week. After this period, a part of the preparations was dissected, another part was immersed in alkaline solution to obtain corrosive casts of vessels.

Results. The greatest number of cases of the gland vascularization (50.0 %) was of type II, which was characterized by mixed presence of long and short branches of the splenic artery in the arterial blood supply of the gland parenchyma. The variant with predominance of short branches (Type I) was the second most frequent (32.5 %). The variant with predominance of blood supply of the gland only due to long branches (Type III) was observed less frequently, in 17 % of cases. In the majority of cases there were numerous arterial anastomoses in the form of arcades in the gland parenchyma (88,2 % of cases). They usually continue large branches of the splenic artery (dorsal pancreatic artery and large pancreatic artery), whereas short branches usually supply only a small part of the gland.

Conclusion. The human pancreas has a marked anatomical variability of its arterial blood supply. The investigation showed that in most cases its parenchyma is vascularized by short and long branches of the splenic artery forming arcade-type anastomoses. In a several cases there was found a variant of blood supply with predominance of short branches dividing the gland into separate sections. The type of blood supply of the gland body and tail with predominance of long branches was found less often.
Arterial and venous thrombosis. Is the Virchow’s triad always valid?
Authors: Vlasov T. D. , Yashin S. M.
Published: April 2022

Despite the success of conservative and surgical treatment of vascular diseases, the prevention of arterial and venous thrombosis remains extremely actual. For more than a hundred years, the so-called «Virchow’s triad» has been used to explain the mechanism of thrombosis: 1–slowing of blood flow; 2–hypercoagulation; 3 – damage to the vascular wall. However, the combination of these factors is fully applicable only for venous thrombosis and limited for arterial thrombosis. The generally accepted strategy for the prevention of venous thrombosis is the use of anticoagulants, while for arterial thrombosis – antiaggregants. In recent years the mechanisms of blood clot formation at high blood flow rates in the areas of arterial stenosis, as well as the role of platelets and von Willebrand factor in this process, were investigated. In the presented review, the details of the mechanisms of thrombosis in the arteries are analyzed and the concept of «arterial triad» is introduced. Arterial triad includes: 1 – arterial stenosis (increase in shear rate); 2 – platelets (their activation and interaction with von Willebrand factor); 3 – damage of the vascular wall. The arterial triad describes the mechanisms of thrombosis in the presence of artery stenosis (usually due to atherosclerosis). Understanding similarities and differences between Virchow’s and arterial triads, will allow us to estimate the risk factors in patients with cardiovascular pathology and develop optimal methods of their prevention.

Published: April 2022

Screening is considered a necessary mechanism for alleviating information asymmetry but has also raised concerns about increased discrimination in online peer-to-peer market platforms. Paradoxically, providers of goods and services may also voluntarily forgo screening, even though it increases the risks and costs associated with poor matches. We examine who may choose to forgo screening and why, and its impact on their performance outcomes. Our study’s empirical context is the Airbnb platform, wherein the “Instant Book” feature enables hosts to forgo the screening of guests. Utilizing a unique panel dataset of all listings in New York City during August 2015-February 2017, we first explore the antecedents of voluntarily switching to instant booking and then causally identify the impacts of switching. Our study provides evidence of the economic benefits of forgoing screening from increased occupancy even as review ratings decline; these effects are stronger for Black and female hosts. We discuss the strategic and social welfare implications of these findings within the context of current conversations on discrimination and bias in the sharing economy.
Online Product Reviews: Is a Finer-Grained Rating Scheme Superior to a Coarser One?
Authors:   Tilburg University, Tunc Murat M. , Cavusoglu Huseyin ,   The University of Texas at Dallas, Raghunathan Srinivasan ,   The University of Texas at Dallas
Published: April 2022

Product review platforms in online marketplaces differ with respect to the granularity of product quality information they provide. While some platforms provide a single overall rating for product quality (also referred to as the single-dimensional rating scheme), others provide a separate rating for each individual quality attribute (also referred to as the multidimensional rating scheme). The multidimensional rating scheme is superior to the single-dimensional rating scheme, ceteris paribus, in reducing consumers’ uncertainty about product quality and value. However, we show that, when sellers respond to product ratings by adjusting their prices, compared to the single-dimensional rating scheme, the multidimensional rating scheme does not always benefit consumers, nor does it necessarily benefit sellers or society. The uncertainty associated with quality attribute rating and the extent of differentiation between competing products determines whether a finer-grained multidimensional rating scheme is superior to a coarser-grained single-dimensional rating scheme from the consumer, seller, and social planner perspectives. The main driver of the results is that more (less) granular and less (more) uncertain information exposes (hides) underlying differentiation, or a lack thereof, between competing products, which, in turn, alters upstream price competition in the presence of heterogeneous consumer preferences. The results demonstrate that focusing on the information transfer aspect of rating schemes provides only a partial understanding of the true impacts of rating schemes.
Examining the Neural Basis of Information Security Policy Violations: A Noninvasive Brain Stimulation Approach
Authors:   University of Melbourne, Turel Ofir , He Qinghua ,   Southwest University, Wen Yatong ,   Southwest University
Published: April 2022

Nonmalicious information security policy (ISP) violations can cause organizations significant harm. Here, we aim to extend the understanding of why employees engage in such acts. A large body of ISP violation research is based on the tenet that people violate ISPs to obtain personal benefits, as explained by rational choice and expectancy theories. But this assumption has only been weakly tested, using mostly correlational approaches. Our objective is to improve the causal basis for this argument by using a noninvasive brain stimulation (NIBS) technique, which actually modulates brain activity in regions of the brain that process value/gain assessments. Therefore, it can substantially increase the claim of causality—that expected rewards lead to ISP violations. To do so, we build on expectancy theory and neuroscience knowledge to theorize why reducing the excitability of neurons in the left dorsolateral prefrontal cortex (L DLPFC) can lower the endorsement of ISP violations. We test this idea in four experiments in which we use a NIBS technique called high-definition direct current stimulation (HD-tDCS). Our findings support the assertion that the L DLPFC is likely involved in the expectancy theory of ISP violations, and that endorsing such violations can be experimentally adjusted with NIBS techniques. These findings extend the understanding of cybersecurity behaviors, improve the causal support for the common assumption made by rational choice theory studies that ISP violations are motivated through perceived benefits, point to the need to consider the L DLPFC in research on positively valenced (or attractive) technology-mediated actions, and pave the way for future use of brain stimulation techniques for stronger causality claims in information systems research.
Reconciling the Paradoxical Findings of Choice Overload Through an Analytical Lens
Authors:   American University, Zhang Nan , Xu Heng ,   American University
Published: April 2022

Too much of a good thing can be harmful. Choice overload, a compelling paradox in consumer psychology, exemplifies this notion with the idea that offering more product options could impede rather than improve consumer satisfaction, even when consumers are free to ignore any available option. After attracting intense interest in the past decades from multiple disciplines, research on choice overload has produced voluminous yet paradoxical findings that are widely perceived as inconsistent even at the meta-analytic level. This paper launches an interdisciplinary inquiry to resolve the inconsistencies on both the conceptual and empirical fronts. Specifically, we identified a surprising butrobust pattern among the existing empirical evidence for the choiceoverload effect and demonstrated through mathematical analysis and extensive simulation studies that the pattern would only likely emerge from one specific type of latent mechanism underlying the moderated choiceoverload effect. The paper discusses the research and practical implications of our findings—namely, the broad promise of analytical meta-analysis (an emerging area for the use of data analytics) and machine learning to address the widely recognized inconsistencies in social and behavioral sciences, and the unique and salient role of the information systems community in developing this new era of meta-analysis.
The Complex Effects of Cross-Domain Knowledge on IS Development: A Simulation-Based Theory Development
Authors:   National University of Singapore, Hahn Jungpil , Lee Gwanhoo ,   American University
Published: April 2022

Information systems development (ISD) requires both business domain and technology domain knowledge. How cross-domain knowledge affects ISD outcomes is one of the most fundamental and persistent problems in the IS field. We argue that the effect of cross-domain knowledge depends on its distribution across business and IT units and ISD complexity in terms of level and pattern of design element interdependencies. We systematically investigate the complex effects of cross-domain knowledge on ISD performance by using simulations based on the NK fitness landscapes model. We find that cross-domain knowledge not only increases ISD performance but also reduces its variability. These effects are greater when ISD complexity is greater. Crossdomain knowledge is found to increase the robustness of ISD performance across different patterns of design element interdependencies. Interestingly, ISD performance is higher when cross-domain knowledge is unevenly distributed across business and IS units and when its distribution pattern matches the pattern of the design element interdependencies. These findings suggest that the effect of cross-domain knowledge on ISD performance is not fixed but depends on its structural pattern, the level and pattern of design element interdependencies, and their interactions. This study illuminates how and why challenges in ISD might be structural and how, why, and when cross-domain knowledge might help to overcome these challenges. We develop a theoretical framework and propositions based on our findings.

Предложена модель оценки системы оповещения (пожарной или комплексной защиты) в АСУП на распределённом объекте защиты без учёта координат. Показаны варианты проведения оценки при помощи минимизации интегрального показателя качества, учитывающего разницу между пороговыми значениями в среде и для срабатывания датчика. Предложенный интегральный показатель каче­ства в созданной модели характеризует общую эффективность покрытия «слепых зон» датчиков на рассредоточенном объекте защиты. Изложенная модель может быть применена при создании автоматизированной системы управления формированием плана мероприятий по защите объектов ТЭК.

The model of evaluation of the warning system (fire or complex protection) on the distributed object of protection without taking into account the coordinates is proposed. The variants of the evaluation by minimizing the integral quality index, taking into account the difference between the thresholds in the environment and for the sensor operation. The proposed integral quality index in the created model characterizes the overall efficiency of the “blind spots” coverage of the sensors on the dispersed protection object. The described model can be applied in the creation of an automated control system for the formation of a plan of measures for the protection of fuel and energy facilities.

Morphology control of carbon nanostructures is essential for improving their performance in many applications. Direct pyrolysis of organic precursors, however, usually yields bulk amorphous carbon. Therefore, traditional methods for controlling the morphology of carbon nanostructures involve multistep processes and complex precursor molecules. While various methods have been developed under ambient pressure, the impact of pressure on the morphology of the resulting carbon nanostructures remains unexplored. Herein, we present the synthesis of carbon nanorods by direct pyrolysis of the low-cost aliphatic hydrocarbon tetracosane under high pressure conditions. The diameters of the carbon nanorods are adjusted by simply varying the synthetic pressures. High pressure allows controlling both the nanorod morphology as well as the degree of order, and local conductivity of the thus prepared nanorods has been confirmed by conductive AFM measurements. Our method promises a convenient strategy to synthesize carbon nanostructures with controlled morphology and high ordered chemical structure, which opens opportunities for potential electronic and electrochemical applications.
High-throughput Nano-DESI Mass Spectrometry Imaging of Biological Tissues Using an Integrated Microfluidic Probe

Nanospray desorption electrospray mass spectrometry imaging (nano-DESI MSI) enables quantitative imaging of hundreds of molecules in biological samples with minimal sample pretreatment and a spatial resolution down to 10 µm. We have recently developed an integrated glass microfluidic probe (iMFP) for nano-DESI MSI, which simplifies the experimental setup and enables imaging with a spatial resolution of 25 µm. Herein, we describe an improved design of the iMFP for the high-throughput imaging of tissue sections. We increased the dimensions of the primary and spray channels and optimized the spray voltage and solvent flow rate to obtain a stable operation of the iMFP at both low (0.04 mm/s) and high (0.4 mm/s) scan rates. We demonstrate the performance of the high-throughput iMFP by imaging mouse uterine and brain tissue sections. We observe that the sensitivity, molecular coverage, and spatial resolution obtained using the iMFP do not change to a significant extent as the scan rate increases. Using a scan rate of 0.4 mm/s, we obtained high quality images of mouse uterine tissue sections (scan area: 3.2 mm×2.3 mm) in only 9.5 minutes and of mouse brain tissue (scan area: 7.0 mm×5.4 mm) in 21.7 minutes, which corresponds to a 10-15-fold improvement in the experimental throughput. We have also developed a quantitative metric for evaluating the quality of ion images obtained at different scan rates. Specifically, by defining regions of interest (ROI) in both a representative ion image and optical image of the tissue section, we calculated the spatial deviation between the two ROIs by counting the number of mismatched pixels. Using this metric, we demonstrate that the percent deviation increases slightly from 6.7% to 10.2 % with an increase in the scan rate from 0.02 to 0.4 mm/s. The maximum experimental throughput achieved in this study is limited by the acquisition rate of a mass spectrometer necessary to achieve the desired spatial resolution and may be further improved using a faster instrument. The ability to image biological tissues with high throughput using iMFP-based nano-DESI MSI will substantially speed up tissue mapping efforts.

A genomic and bioactivity informed analysis of the metabolome of the extremophile Amycolatopsis sp. DEM30355 has allowed for the discovery and isolation of the polyketide antibiotic tatiomicin. Identification of the biosynthetic gene cluster was confirmed by heterologous expression in Streptomyces coelicolor M1152. Structural elucidation, including absolute stereochemical assignment, was performed using complementary crystallographic, spectroscopic and computational methods. Tatiomicin shows antibiotic activity against Gram-positive bacteria, including methicillin resistant Staphylococcus aureus (MRSA). Cytological profiling experiments suggest a putative antibiotic mode-of-action, involving membrane depolarisation and chromosomal decondensation of the target bacteria.
Structural Diversity in Oxoiridates with 1D IrnO3(n+1) Chain Fragments and Flat Bands

Published: April 2022

A previously unreported series of hexagonal-perovskite-based Rb-oxoiridates, Rb5Ir2O9, Rb7Ir3O12, and Rb12Ir7O24, have been synthesized and structurally analyzed via N2-protected single-crystal X-ray diffraction (SC-XRD). These materials exhibit different 1D IrnO3(n+1) chain fragments along their c axes. IrO6 Octahedra and RbOx (x = 6, 8, and 10) polyhedra are their basic building blocks. The IrO6 octahedra are linked via face-sharing, forming Ir2O9 dimers, Ir3O12 trimers, and Ir7O24 heptamers. The nonmagnetic RbOx (x = 6, 8, and 10) polyhedra serve as both bridging units and spacers. Temperature-dependent SC-XRD shows all three to display positive thermal expansion and rules out structural transitions from their triangular symmetries down to 100 K. Density functional theory results suggest semiconducting-like behavior for the title compounds. The flatness of the electronic bands and our structural analysis are of potential interest for understanding and designing 1D quantum materials.
