Review Article On Recent Trends in Surgical Techniques for High-grade Spondylolisthesis
Authors: Sakhrekar Rajendra
Published: July 2022

Introduction: High-grade spondylolisthesis is defined as cases with more than 50% displacement and spondylolisthesis with Meyerding grade III and higher. The surgical management of high-grade spondylolisthesis is highly controversial. Many surgical methods have been reported like posterior in situ fusion, instrumented posterior fusion with or without reduction, combined anterior and posterior procedures, spondylectomy with reduction of L4 to the sacrum (for spondyloptosis), posterior interbody fusion with trans-sacral fixation. Minimally invasive transforaminal lumbar interbody fusion for high-grade spondylolisthesis has also been recently mentioned in literature. This study aimed to review the recent literature which has described the surgical outcomes associated with various surgical techniques used for high-grade spondylolisthesis Materials and Methods: Recent articles were searched on search engines such as PubMed, Google Scholar with the use of Keywords like ‘High-grade Spondylolisthesis’, ‘Surgical Techniques’ ‘complications’. Discussion: The surgical management of high-grade spondylolisthesis is an area of significant controversies. The literature is replete with regards to need for reduction, need for decompression, levels of fusion, the nature of instrumentation, surgical approaches including open, minimally invasive, and “mini-open” procedures, as well as various techniques for reduction of the slip and fusion strategy. The three basic options of high-grade spondylolisthesis include in-situ fusion, partial reduction and fusion, and complete reduction. Conclusion: Various techniques have been described for high-grade spondylolisthesis. Spine Deformity Study Group (SDSG) classification gives guidelines about balanced and unbalanced pelvis and advising reduction and fusion in case of unbalanced pelvis for correction of biomechanical and global sagittal alignment. Each of the surgical techniques has their own advantages and disadvantages. Although individual authors’ experience, skill levels, anatomic reduction with fusion techniques has yielded highly encouraging results. Keywords: High-grade spondylolisthesis, Surgical techniques, In situ fusion, Reduction and fusion, Complications

Published: July 2022

Purpose: The aim of this article is to provide an updated review on most commonly used modalities to treat avscular necrosis of femoral head. A thorough literature search was performed using predetermined criteria. Recent Findings: Systematic evaluation for decisions about management demonstrated the following: (1) Though efficacy is vague and controversial non-operative treatments, pharmacological treatments or core decompression can be used in symptomatic medium-sized pre-collapse lesions. (2) In spite of known complications to no vascularized bone graft,vascularized bone grafts and osteotomies -medium to larger-sized lesions can be dealt with them (3) In post-collapse stages, they should be treated with joint preserving techniques, such as hip surfacing, nonvascularized bone graft,vascularized bone grafts (4) If post-collapse and acetabular involvement ensues, arthroplasty is indicated. (5) Cell-based and biological forms of treatment in form of bone marrow aspirate, stem cells, BMP have shown inconclusive results, and further research is needed to assess their role in the management of this condition. Methods: Recent articles were searched on search engines like PubMed, Google Scholar and references of different articles were checked. Summary: There is a need to overview the management options for avascular necrosis of the femoral head. This review discusses different management modalities available along with their advantages and disadvantages. Keywords: AVN femoral head, Non-operative treatment, Biophysical management, Operative treatment
An agnostic approach to gender patterns in parliamentary speech: a question of representation by topic and style
Authors: Raiber Klara , Spierings Niels
Published: July 2022

By examining all speech in the 18th legislative period (2013–17) of the German Bundestag, including 6,598,831 words in 51,337 text segments, we compare women’s and men’s parliamentary speech. Our approach builds on the agnostic view on representation and follows a bottom-up approach, which avoids pre-set definitions of what is women’s or men’s language use. By analysing the frequencies of the most used words and keywords from semantic networks, we find four notable descriptive patterns. First, female members of parliament tended to talk more about stereotypical ‘feminine’ policy issues like, for instance, contraception. Second, female members of parliament put people more central in their language, while male members of parliament focused more on Germany as a country. Third, women focused more on procedures than men. Lastly, female members of parliament used a politer language style, for instance, by thanking others, more than male members of parliament.

Evidence suggests that quarantine might have a wide-ranging, substantial, and long-lasting negative psychological impact especially when the necessary preventive measures are not taken. This study assessed the prevalence and associated factors of depression and anxiety among quarantined population during the COVID-19 outbreak in central Ethiopia. A community-based cross-section study was conducted among individuals under quarantine from June 5 to July 5, 2020, in Addis Ababa, Ethiopia. The hospital Anxiety and Depression Scale (HADS) was used to assess depression and anxiety. Binary logistic regression analysis (multivariate analysis) was used to identify the potential determinants of depression and anxiety. A total of 297 participants were included in the study which makes the response rate 90.8%. The prevalence of anxiety, depression, and co-morbid anxiety and depression were 21.5%, 70.7%, and 15.8% respectively. In our multivariable analyses, stressful life events (AOR 2.61, 95%CI (1.46, 4.67)), spent time on sleeping (AOR 1.97, 95% CI (1.08, 3.62)), and believing that COVID-19 could be prevented by wearing a glove (AOR 0.30, 95% CI (0.11, 0.81)) showed a statistically significant association with anxiety, whereas being married (AOR 2.67, 95% CI (1.37, 5.22)), had stressful life event in the last six months (AOR 1.44, 95% CI (1.44, 5.25)) and spending of time by sleeping during the quarantine (AOR 1.97, 95% CI (1.42, 6.19)) predicted depression. In conclusion, the current study result indicated that a considerable proportion of individuals who were under quarantine during the COVID-19 pandemic have experienced psychological disturbances, such as anxiety and depression. The results suggest that attention needs to be given to mitigate mental health problems in the quarantined population during the COVID-19 outbreak.
Divergent confidence intervals among pre-specified analyses in the HiSTORIC stepped wedge trial: An exploratory post-hoc investigation
Authors: Parker Richard A. , Keerie Catriona , Weir Christopher J. , Anand Atul , Mills Nicholas L.
Published: July 2022

Background

The high-sensitivity cardiac troponin on presentation to rule out myocardial infarction (HiSTORIC) study was a stepped-wedge cluster randomised trial with long before-and-after periods, involving seven hospitals across Scotland. Results were divergent for the binary safety endpoint (type 1 or type 4b myocardial infarction or cardiac death) across certain pre-specified analyses, which warranted further investigation. In particular, the calendar-matched analysis produced an odds ratio in the opposite direction to the primary logistic mixed-effects model analysis.

Methods

Several post-hoc statistical models were fitted to each of the co-primary outcomes of length of hospital stay and safety events, which included adjusting for exposure time, incorporating splines, and fitting a random time effect. We improved control of patient characteristics over time by adjusting for multiple additional covariates using different methods: direct inclusion, regression adjustment for propensity score, and weighting. A data augmentation approach was also conducted aiming to reduce the effect of sparse data bias. Finally, the raw data was examined.

Results

The new statistical models confirmed the results of the pre-specified trial analysis. In particular, the observed divergence between the calendar-matched and other analyses remained, even after performing the covariate adjustment methods, and after using data augmentation. Divergence was particularly acute for the safety endpoint, which had an event rate of 0.36% overall. Examining the raw data was particularly helpful to assess the sensitivity of the results to small changes in event rates and identify patterns in the data.

Conclusions

Our experience reveals the importance of conducting multiple pre-specified sensitivity analyses and examining the raw data, particularly for stepped wedge trials with low event rates or with a small number of sites. Before-and-after analytical approaches that adjust for differences in patient populations but avoid direct modelling of the time trend should be considered in future stepped wedge trials with similar designs.
Parménides (28B16DK) en el De Sensibus de Teofrasto: ¿percepción o cognición?
Authors: Aguirre De la Luz Nazyheli
Published: July 2022

Entre los fragmentos del poema de Parménides de alta densidad conceptual, aparece el fr. 28B 16 DK, transmitido por doble vía por los dos peripatéticos más importantes, Teofrasto y Aristóteles, que lo discutieron con variable grado de profundidad y en contextos muy diferentes. Dada la nada insignificante complejidad inherente a dicho texto —que se oscila entre ver como una doctrina parmenídea relativa a la percepción sensorial o a la cognición—, su correcta interpretación exige considerar no sólo el contexto en que es citado, sino también hacer cuentas con el eventual comentario que lo acompaña. Por ello, en el presente trabajo se hará un análisis del ejercicio exegético que sobre estos cuatro versos quedó plasmado en el largo fragmento conservado del De Sensibus de Teofrasto, que consistirá en un examen minucioso de las principales equivalencias léxicas y conceptuales entre los términos utilizados por Parménides y su traslado al vocabulario del Perípato por cuenta del Eresio.

Seguridad, fronteras y Gendarmería Nacional en la Argentina contemporánea
Authors: Glanc Laura
Published: July 2022

Gendarmería Nacional Argentina (GNA) es una fuerza de seguridad federal, de naturaleza militar con características de fuerza intermedia, dependiente del Ministerio de Seguridad de la Nación. Si bien la GNA surge con la finalidad de proteger el límite internacional de las fronteras nacionales, cuya función primordial ha estado relacionada con delitos federales y problemáticas de alta conflictividad, desde la década de 2000 se le añadió a sus actividades centrales, el policiamiento en «barrios urbanos conflictivos». Recientemente, bajo la presidencia de Mauricio Macri (2015-2019), los operativos de seguridad de GNA en zonas urbanas de conflicto siguieron ocupando un lugar destacado, pero, su discurso gubernamental al focalizar en la «lucha contra el narcotráfico», elevó el problema de la seguridad a un plano nacional. De aquí, la necesidad de fortalecer las «fronteras calientes» para su protección. En este artículo focalizaremos en este proceso de gestión de la seguridad del gobierno de Mauricio Marcri (2015-2019), a través del cual se puso énfasis en las «fronteras» como sector securitario para el tratamiento del «narcotráfico» como problema nacional. Por ello, principal atención se le dará a una frontera del norte argentino que limita con Brasil y al rol en las tareas de seguridad que desempeña la GNA. La metodología utilizada fue primordialmente de carácter cualitativo. Se llevaron a cabo entrevistas a funcionarios civiles y también a uniformados de GNA, las cuales se complementaron con el análisis de decretos y normativa relacionada.
La ubicuidad de la comunicación en la gestión de la extensión universitaria. Un análisis sobre el Programa Integral APEX de la Universidad de la República
Authors: Olivetti Espina Miguel
Published: July 2022

Se aborda el desarrollo de prácticas y saberes provenientes del campo de la comunicación en el Programa APEX (Aprendizaje y Extensión) de la Universidad de la República (Uruguay). De esta forma se expone una serie de elementos sustantivos de los paradigmas epistemológicos que sostienen la configuración del Programa. También se proporcionan aportes respecto de su organización institucional, de la importancia del pensamiento de la comunicación, y de su devenir histórico. En el entramado expositivo aparecen nodos de singular relevancia: 1) el desarrollo de la Plataforma “Comunicación y Territorio”, que contribuye, desde el análisis crítico del discurso, al abordaje de problemáticas territoriales y 2) la condición de ubicuidad de la comunicación en la gestión del Programa APEX. Se sustenta así la idea de que la comunicación y la extensión son campos de articulación claves para el paradigma de la integralidad, donde los aportes teóricos y metodológicos del campo de la comunicación resultan pertinentes a la hora de actualizar abordajes territoriales y comunitarios en la extensión universitaria.

Pensar lo impensable: apunte antropológico sobre la guerra
Authors: Ramos Castro David
Published: July 2022

La guerra entre Rusia y Ucrania nos interpela a todos en nuestra condición histórica y cultural presente. Además de otro indicio de aceleración histórica, nos obliga a pensar en las definitivas consecuencias de una posible guerra mundial cuyas fuerzas atómicas y nucleares podrían aniquilar todo el planeta. En este artículo reflexiono al respecto desde un planteamiento antropológico. Es un punto de vista justificado por la amenaza total a toda forma de vida, por la hegemonía tecnocientífica que la ha incrementado y por la incapacidad de crear una cultura global que no parta de la vieja y reductora oposición política entre el amigo y el enemigo, y que desmienta la supuestamente inevitable agresividad del animal humano como algo independiente de sus condiciones socioculturales. Tal incapacidad se manifiesta en la guerra paralela de las imágenes mediáticas en su presentación del Otro y en las que Occidente ha confundido las nociones de visibilidad, poder e influencia con sus usos más recientes de las mismas. El posible resultado final, sobre el que más debemos pensar cuanto más impensable nos parezca, significaría no sólo la extinción de todo porvenir, sino la aniquilación de todo lo que fue, como si nunca hubiéramos existido.

Después de siglos en los que el arte era fundamentalmente religioso y mayoritariamente cristiano, la ruptura del mundo artístico moderno con la Iglesia, unido al abandono de los cánones clásicos, sumió al arte religioso en una grave crisis al nivel intelectual y también material. Esto nos lleva a hacerlos la pregunta por la posibilidad de un arte cristiano contemporáneo que pueda hablar a los hombres de hoy y llevarlos a Dios desde la experiencia estética, o si, por el contrario, se hace necesario optar por un arte continuista con las épocas pasadas que, sin embargo, pueda conectar con las inquietudes contemporáneas.

Published: July 2022

Background and Purpose: Patients over the age of 75 are more likely to develop epilepsy than children under the age of 10. Patients of all ages are prescribed anti-epileptic drugs; however, those over the age of 65 are the most typically prescribed group.Methods: This is a retrospective study of geriatric cases admitted to the Neurosurgery Department in Khoula Hospital from January 1, 2016 to December 31, 2019. A medical records of 669 patients were identified. Patients' demographics, risk factors, usage of anti-epileptic drug (AED), type of tumor, tumor location, neuro-vital signs diagnosis, Glasgow coma scale on arrival, treatment types, and length of stay (LOS) were recorded.Results: The prevalence of AEDs use was 19%. Patients with traumatic brain injury (TBI) were found to have a higher rate of using AEDs (32.1%) followed by patients with oncological and vascular pathologies, respectively (30.1% and 21.6%). There was a significant relationship between the utilization of AEDs among different neurological diseases investigated (p<0.05). Patients who received surgical interventions were using AEDs much more than patients with conservative management (p=0.001). There was a significant difference in the LOS and the usage of AEDs. Added to that, the results signify a relationship between the intensive care unit (ICU) admission and the utilization of AEDs in which the majority of the patients who were not on AEDs were not admitted to the ICU (p<0.05). Phenytoin was the most commonly used AED among different neurosurgical pathologies in the present study (n=110).Conclusions: AEDs are used as prophylaxis to prevent seizures before most neurosurgical procedures and were commonly prescribed in TBI patients. Phenytoin was found to be the commonest AEDs utilized among the different neurosurgical categories followed by levetiracetam.

The impact of the ongoing Covid 19 pandemic which entering the beginning of 2021 has leads to changes the way humans interact. Previously interaction was done directly face to face, but now the pandemic forced affected humans to interact more using social media. This condition leads to the question of how the human self looks in it. Is there any changing or not? How they were change? And how it potentially creates a symbolic world with artificial behavior that we knew as hyperreality? The research was conducted using a qualitative descriptive method, with purposive sampling, between March 2020 and August 2020 which was the initial period of pandemic quarantine. It was assume that in this period social media users started to shape their appearance on social media. Based on the results of the conducted research, three types of self-appearance emerged, they were the social interaction appearance; Personal appearance; and Busy appearance. All the types of selfappearance created a world that we knew as hyperreality. In this world, the office workers dedicated themself to be at their best in social media appearance while the reality behavior was not always the same. It then creates a notion that social media appearance were far more important and meaningful then the everyday reality

Lay first aid giving as a specific traumatic experience
Authors: Kurečková Veronika , Řezáč Pavel , Trepáčová Martina , Zámečník Petr
Published: July 2022

Despite first aid process has mainly been considered a medical or technical issue; it seems obvious that psychological and social aspects play an important role too. As a pilot study we interviewed ten helping bystanders about their ideas and feelings during and after the first aid. Their reports were analysed, using a qualitative approach. There were various feelings and ideas respondents experienced – temporary blockade, limited ability to recall relevant information, performance decrease, time distortion, selective perception, strong subjective stress. After first aid people experienced doubts about their acts and decisions, quilt and failure feelings, specific relationship between the rescuer and rescued person, feeling of non-terminating, PTSD symptoms, strong need to share the experience. Our respondents reported long lasting discomfort, persisting even years after the experience. Psychological aspects of lay first aid giving are a crucial aspect influencing the efficacy of first aid process but also the future well-being of lay rescuers and should therefore be considered more.

Authors: Qiu Tian , Lin Zhiquan , Tsai Chen Jung , Wong Chi Shing , Zhang Xin , Liu Shuaiqi , Ning Honglong
Published: July 2022

Manual inspection is still widely used for defect detection in optical isolator factories. The manual method is not only inefficient, but also low reliability, and easy to be disturbed by visual fatigue. This paper proposes an automatic defect detection algorithm for optical isolators, which is an extension to a previous conference paper, with more algorithms and detailed description of the detection algorithm added. In the focusing part of the algorithm, an improved Laplace operator which increases the attention of oblique gradient is adopted. In the detection part of the algorithm, the image-enhancement based on adaptive threshold, the line and ring detection based on Hough transform, and process the detection results by clustering method are used. Experiments show that the scheme proposed in this paper can inspect a series of defects on the crystal area of the optical isolator in real time, the manpower demand can be reduced to less than 10 % and the detection accuracy is 93 %.

Published: July 2022

Objectives

Urinary luteinizing hormone (uLH) and urinary follicle-stimulating hormone (uFSH) have been shown to be useful screening and management tools for children with central precocious puberty. However, studies on uLH and uFSH reference intervals are scarce. Therefore, we aimed to establish reference intervals for uLH and uFSH, according to age, sex, and pubertal status in apparently healthy children aged 6–11 years.

Methods

We performed detection capability, precision, accuracy by recovery, linearity, agreement analysis, and stability testing to analyze the method performance of uLH and uFSH. The Clinical Laboratory Standards Institute’s C28-A3 criteria was used to establish the reference intervals.

Results

Both uLH and uFSH were stable at 4 °C for 52.6 h and 64.8 days, respectively. The total imprecision of uFSH is within the manufacturer’s claim, while the total imprecision of uLH remained within tolerable bias. Both uLH and uFSH could be measured with acceptable detection capability. The recovery rates of the hormones were 87.6–98.8% and 102.8–103.4%, respectively, and therefore within acceptable limits. There were significant correlations between the serum and urine concentrations (LH: r=0.91, p<0.001; FSH: r=0.90, p<0.001). The reference intervals of uLH and uFSH were established according to age, sex, and pubertal status.

Conclusions

We established reference intervals for uLH and uFSH based on age, sex and pubertal status to provide a non-invasive clinical screening tool for precocious puberty in children aged 6–11 years.

Published: July 2022

Objectives

The aim of this study was to determine the appropriate transport and storage conditions for blood taken for direct renin concentration and plasma renin activity measurement, and whether cryoactivation of prorenin is seen at time points relevant to clinical practice.

Methods

Blood was extracted from n=10 volunteers into K2-EDTA tubes. Stability of renin was assessed in whole blood stored at room temperature (15–25 °C) and in the refrigerator (2–8 °C) at 0 h, 8 h, and 24 h. The stability of renin in plasma was determined under the same conditions at 0 h, 24 h and 72 h.

Results

Stability of plasma renin activity and direct renin concentration in whole blood stored at room temperature was found to be acceptable for up to 24 h. At refrigerated temperature, whole blood stability was acceptable for measurement of direct renin concentration up to 8 h and plasma renin activity up to 24 h. In contrast, plasma renin activity was not stable in plasma stored at either room or refrigerated temperatures up to 24 h; however, direct renin concentration had acceptable stability in plasma stored at room temperature for up to 24 h, but stability was unacceptable at refrigerated temperatures.

Conclusions

Samples collected for plasma renin activity and direct renin concentration should be transported as whole blood to optimise stability. After sample processing, plasma can be kept at room temperature for up to 24 h for direct renin concentration, however, for determination of plasma renin activity separated plasma should be analysed or frozen as soon as possible.
The future of care and clinical research in autism — recommendations from the 2021 Lancet Commission
Authors: Yu Xiang , Xu Xiu
Published: July 2022

At least 78 million people worldwide are affected by autism, a neurodevelopmental disorder characterized by deficits in social interactions, and repetitive behaviors and/or interests. Autism typically manifests in early childhood, and affects social communications and behaviors throughout the lifespan of the individual. Under the umbrella of autism spectrum disorder, it is a highly heterogeneous disorder, with some individuals profoundly affected and needing care every day, while others can live highly independent lives, with some adjustments. The past 60 years has seen a major influx of interest in autism, and significant advances in many areas. However, a large gap remains between current scientific knowledge and the help and support that people with autism and their families need. To address these concerns, the Lancet commissioned a report on the “future of care and clinical research in autism”. The Commission calls for government coordination between health-care, education and social sectors, as well as active participation from people with autism and their families. The Commission proposes personalized, evidence-based assessments and intervention, that is accessible and affordable to all, and call for increased appreciation of neurodiversity and prioritization of research that can improve the lives of people with autism and their families. How to support each and every autistic individual and their families is highly challenging. The 64-page Lancet Commission Report, published on December 2021, was written jointly by 32 authors from 6 continents and 13 disciplines, including clinicians, other health-care providers, researchers, advocates, autistic individuals and their parents.

Theoretical investigation of some 1,2,4-triazole-based molecules synthetized
Authors: Turhan Zeynep Şilan , Tenlįk Figen
Published: July 2022

In this study, theoretical calculations were made and interpreted to obtain chemical, nonlinear optical properties and antibacterial activity parameters of 14 registered heterocyclic 4, 5-dihydro-1H-1, 2, 4-triazole-5-one derivatives in the literature. For this purpose, first of all, 14 compounds registered in the literature and two main structures were optimized to find the minimum energy and the most stable structure by using the “B3LYP/6-311++G (d, p)” methods. HOMO–LUMO energies calculated from these optimized structures, energy differences and chemical parameters derived from HOMO–LUMO energies (I; Ionization potential, A; electron affinity, ΔE; Energy Gap, χ; electronegative σ; molecular softness, ω; Electrophilic Index, ε; Nucleophilic Index, μ; Chemical Potential) values were determined. In addition to chemical parameters, polar calculations were made for nonlinear optical properties, and it was evaluated whether the compounds could be optical materials. Finally, the antimicrobial properties of the molecules were calculated theoretically and compared with the experimental results by calculating the volume.

Transnational Rivalries and Left Politics: An Amsterdam School Perspective on Turkey's “Ergenekon” Trials
Authors: Şenalp M. Gürsan , Küçüker M. Can , Şenalp Esra Şengör
Published: July 2022

The Ergenekon trials were among the most controversial issues in the recent political history of Turkey. It is still worth reconsidering the liberal, nationalist, and socialist-left circles' variegated responses to the subject matter. The first two were doomed to fail since each attached itself to one side of the intra-state struggles. Although the socialist left's approach was enlightening in many ways, there is a significant shortcoming in its theoretical references to explain the inherent transnational rivalries. An alternative research agenda offered by the Amsterdam School could enrich its conceptual toolkit in more comprehensive ways. To evaluate this potentiality, we need to engage in two conceptual problems regarding the theory: 1) Could the concept of state-class be helpful to analyze the political economy of Turkey's Ergenekon trials? 2) Could any key social/class force be distinguished to shed light upon the transnational aspect of the process?
Influence of ambient temperature on electrical properties of varistor-positor structure

Published: July 2022

Recently, the combined two-layer structure based on varistor ceramics and polymer posistor nanocomposites with carbon filler (known as PolySwitch resettable fuses) has been seen as one of the promising elements for protecting electrical circuits from long-term overvoltages. The varistor and posistor layers are in thermal contact. The main functional property of such a structure is a sharp increase (by several orders of magnitude) in the electrical resistance of the posistor nanocomposite layer during the transfer of thermal energy from the varistor layer heated by overvoltage. Detailed information about the behavior of such combined varistor-posistor structures under different conditions, particularly in different temperature conditions, is necessary for the effective technical application of such structures as electrothermal overvoltage limiters. This paper offers research results on the effect of ambient temperature on the electrical characteristics of such voltage limiters. Structures based on metal oxide ceramics used in the production of serial varistors VCR 14D and a posistor nanocomposite for FRX-type PPTC fuses were used in the experiments of this study. It has been established that with an increase in the ambient temperature, the temperature and output voltage of such a device change insignificantly in the limitation region, while the current and power dissipation of the layers significantly decrease. At a fixed ambient temperature, the total power dissipated by the varistor and posistor layers practically does not change in the range of input voltage limitation. The dependence of the power dissipated by the varistor layer on the input voltage is identical to the analogous dependence of the current, and the power dissipation of the posistor layer tends to increase.
Electrical conductivity of thermosensitive glass-ceramics based on nanosized vanadium dioxide

Published: July 2022

The metal-semiconductor phase transition (MSPT) in vanadium dioxide is accompanied by an abrupt change in a number of physical parameters of this compound, in particular the resistivity. Of great interest are glass-ceramic materials, which are synthesized on the basis of vanadium dioxide and glass of the V2O5 — P2O5 system. Electronic devices based on such materials can operate at high electric currents. This allows you to create elements known as threshold switches and critical thermistors. This paper presents the results of the study of electrical conductivity and microstructure of thermosensitive glass-ceramics synthesized on the basis of fine crystalline VO2 with crystal sizes of 5—10 μm and on the basis of nanocrystalline VO2 (crystal size 70—100 nm). In general, microstructures are typical for such materials and contain crystals of vanadium dioxide, inclusions of vanadium phosphate glass and other components of glass ceramics. There are also pores in the microstructure of the samples. The temperature dependences of the resistivity for both types of glass-ceramics have a sharp change in the resistivity by 1.5—2 decades in the region of 70°C, which is characteristic of the MSPT in vanadium dioxide. For both types of glass-ceramics, a comparative study of the resistivity during cycling through the phase transition temperature in VO2 was performed. Glass-ceramic samples synthesized on the basis of nanocrystalline VO2 showed much more stable behavior. This allows creating a stable glass-ceramic material for thermistors with a critical temperature of about 70°C.
