Nodular fasciitis as cause of lateral neck tumor
Authors:   Sanatorio Otamendi Buenos Aires. Argentina., Montesinos Manuel R. , Montesinos María F. , Iotti Alejandro
Published: June 2024

Nodular fasciitis is a rare and benign neoplasm of the soft tissues that can occur in any region of the body and require surgical treatment. We report the case of a 41-year-old female patient with a lateral neck tumor which reached a size of 74.7 × 32.5 mm after two years. The tumor was completely removed under general anesthesia. The pathological examination reported proliferation of myofibroblasts, suggestive of nodular fasciitis. The patient evolved homolateral Claude Bernard Syndrome, without local complications and mild weakness of the ipsilateral arm which improved after 60 days with kinesiotherapy. This condition should be considered among the differential diagnoses of lateral neck tumors.
La fonction de restauration identitaire des échanges interpersonnels hors normes des incarcéré(e)s
Authors:   Université de Nantes (Francia), Galatanu Olga
Published: June 2024

We propose a semantic-discursive analysis of the «non-standard» epistolary exchanges that incarcerated people sentenced to heavy sentences can have with people who do not belong to the judicial or police institutions, nor to the media, nor to their community family. We start from the postulate that these exchanges represent discursive devices (DD) likely to participate in a process of restoring the identity of incarcerated people, or even to trigger it. We propose to develop a conceptual model of this process at the intersection of the reconceptualization of criminal acts and three major themes: victimization, guilt and responsibility, defence and self-argumentation.
Les silences de Rouletabille ou de l’implicite dans l’inférence romanesque
Authors:   Universidad de Las Palmas de Gran Canaria (España), Ventura Daniela
Published: June 2024

"According to Maingueneau (1990: 78), «L’œuvre littéraire est par essence vouée à susciter la quête des implicites». This occurs particularly in Mystery stories, in which the detective discovers the murderer by reasoning. To support his thesis to his audience, he puts into words the mental process that led him to the discovery. His inferential discourse often presents ellipses that the interlocutor (and the reader) is supposed to fill. We will focus our attention on the implicit in the inferential discourse of Rouletabille, reporter-detective, creation of the novelist Gaston Leroux. Our approach to the literary text is part of the field of language sciences, in the broad sense, and touches, among other fields of knowledge, on logic and rhetoric."
The Ultimate Injustice: States' Failure to Take Steps to Prevent Wrongful Convictions and, when Wrongful Convictions are Exposed, to Provide Adequate Assistance to Exonerees
Authors: Lahera Natalie
Published: June 2024

Among the many rights guaranteed by the Constitution are the rights to a presumption of innocence, equal protection, due process, a speedy trial, a trial by jury, and legal counsel, if indigent and charged with a serious crime. But those rights do not ensure that the justice system succeeds every time. The United States has exonerated over 3,000 individuals since 1989. The exonerees have collectedly lost over 26,700 years of their lives. Each exoneration has provided insight into the causes of wrongful convictions, the issues with current compensation laws, and even the changes that need to be implemented to avoid further injustice. Additionally, there are thousands of individuals still incarcerated today for wrongful convictions. Therefore, it calls into question what America is doing to prevent wrongful convictions and to compensate its victims as they transition back into the community. The answer is not enough.
Beyond the Glass Ceiling: Panes of Equity Partnership
Authors: Arnow-Richman Rachel
Published: June 2024

This Article, prepared for a “micro-symposium” on Professor Kerri Stone’s monograph Panes of the Glass Ceiling (2022), explores the partnership pay gap in large law firms and the role of high-profile litigation in facilitating pay equity. There is a rich literature and extensive data on the gender attainment gap in elite law firms, particularly with regard to women’s attrition from practice and poor representation within the partnership ranks. Less attention has been paid to the way in which the exceptional women who achieve equity partner status continue to lag behind their male peers. This Article explores “Women v. BigLaw,” a cluster of equal pay cases brought by women partners in the late 2010s against elite firms. Using Stone’s work as a lens, it reveals how the same unspoken beliefs that underlie the law firm glass ceiling operate above it, placing women partners at the bottom of a new compensation hierarchy centered on origination credit. Due to historical allocations, a culture of deference toward male rainmakers, and implicitly biased attorney development and evaluation practices, origination operates as a form of “legacy credit” that locks in preexisting entitlements favoring male partners. Despite this, gender equity in law practice has been framed principally as a professional value, not a legal imperative. Women v. BigLaw and the unprecedented use of the court system by women lawyers reveals, however, that partnership pay practices pose a liability risk to firms. This new reality may incentivize structural change in ways that attention to gender equity as a managerial and professional goal could not.
“I Felt Misunderstood by the World”: The Interplay of Fame, Adversity, and Identity in Bonnie (Mbuli) Henna’s Autobiography Eyebags & Dimples
Authors: Motahane Nonki , Nyambi Oliver
Published: June 2024

Bonnie (Mbuli) Henna’s autobiography, Eyebags & Dimples (2012), navigates the intricate and multifaceted interplay between fame, adversity, and identity in a uniquely South African post-colonial context. Through an ‘interested’ (re)memorialisation of her journey of becoming a black female celebrity, Henna unveils the complexities of becoming and being a celebrity in a transitioning society marked by pervasive historical legacies of institutionalised disadvantage, shifting notions of gender, and agency. Focusing on what is remembered and how it is remembered for specific aesthetic and perspectival effects, this article examines Henna’s identity project in Eyebags & Dimples. It explores how autobiographical memory in the text becomes, for Henna, a technology of the self she implements to grapple with profound internal struggles inhabiting her (celebrity) identity. Deploying theories of self-writing and memory, the article centres on Henna’s portrayal of adversity – its past location in the colonial home and township and its persistence in family relations – to understand the nature of memory-assisted self-(re)identification processes. The article argues that adversity emerges in Eyebags & Dimples as a transformative force that allows Henna to inscribe history, race, mental health, and family onto her consciousness of being famous. Within this context, Henna’s celebrity identity is completed as re-formed through the narrative stabilisation of the tension between her public fame and personal struggles.
The Church and Migration during Apartheid Times: Roman Catholic Missionaries Banned from Former Homeland of Qwaqwa – Witsieshoek
Authors: Mofokeng Dikotsi William
Published: June 2024

The unjust policies of the apartheid government, which came to power in 1948, made the proclamation of the message of the Gospel difficult for the Roman Catholic missionaries. Catholicism has always determined to communicate the Gospel in ways that engender transformation. However, the apartheid laws in South Africa hindered foreign missionaries from reaching out to the communities which were on the periphery.  There was an element of the Roomse gevaar in the apartheid policies. The idea of the ‘Roomse gevaar’ (the Roman Danger) prevailed in the Afrikaans-speaking community and the corridors of the apartheid regime.
This article presents a historical survey of attitudes towards the missionaries of the Catholic Church in the Eastern Free State during the apartheid regime. It further investigates the impact of the Catholic Church on historical developments in the former Basotho homeland. This research adopts a combination of socio-historical and narrative approaches. The data-gathering technique is the main source of historical books, unpublished and Internet materials. The research is conducted in the form of a comparative Literature study. It draws from Literature on the historical book Patience Our Daily Bread – The Catholic Church in the Orange Free State and Kimberley from 1850 in the work of Professor J.B. Brain as the main source and my Thesis titled: The mission of God’s people in the light of God’s mission. A Missiological case study on the Catholic Church of Bethlehem, South Africa, and other sources will be incorporated into the discussion. The Eastern Free State is the area of focus, with the Qwaqwa homeland being the main focus.
“We Have Been Saying This for Thirty Years!”: Exploring Discursive Technologies of Disappearing African Feminist Knowledges
Authors: Bennett Jane
Published: June 2024

One of the most difficult challenges facing African feminist knowledge production on gendered and sexual violence is its persistent erasure. Despite decades of rich, complex, multimodal and wide-ranging discourse on the meanings of gendered and sexual violence in contexts embedded in colonial legacies of racist and class-based systems, ideas as ordinary to African feminist activism as “rape is not sex; rape is violence” (a mantra of early Rape Crisis teaching in the late 1970s) get systematically “disappeared” by what Gqola calls “rape as a language”. In this article, I explore some of the agnotological technologies at work in disappearing key understandings of gendered and sexual violence, understandings developed through feminist activisms and research. The South African context informs the thinking, which entails rigorous concern with theorisations of gendered and sexual violence rooted in historical and contemporary discussions of race and racialisation. A key difference between Northern-oriented and Southern grapples with questions of gendered and sexual violence lies in Southern integrity regarding the death grip of colonialities and the concomitant epistemological imperative of revolution against these. In the article, I work with a group of participants based in the highly public and effective Western Cape Network on Violence Against Women together with a particular instance of gendered violence against women (Enhle Mbali’s accusation of domestic violence against Black Coffee, in 2021) where it is possible to watch the recirculation of ideas long debunked by African feminist activism. I argue for an approach to knowledge creation alert to the politics of “disappearance".

Published: June 2024

Background. Recently, micronized adipose tissue (MAT) grafts have shown promising results in wound healing, including diabetic ulcers. Objective. To assess the possibility of using 3D printed MAT niche grafts in the management of skin and soft tissue defects resulting from non-melanoma skin cancer (NMSC) resections. Materials and Methods. A retrospective feasibility study was conducted on patients with skin and soft tissue defects resulting from NMSC resections. Twenty-one patients were treated using either artificial dermis (n = 11) or MAT niche (n = 10) grafting. Healing time and POSAS scores were compared. The Mann-Whitney U test and the Pearson chi-square test were used in statistical analysis to compare between and within groups based on preoperative and postoperative measurements. Results. Wounds in the MAT niche group reepithelialized significantly faster than those in the artificial dermis group (mean [SD] 39.2 [11.4] days vs 63.7 [34.8] days; P = .04). In the 21 scar parameters evaluated, the MAT niche group demonstrated significantly superior outcomes in only 2 parameters based on operator assessment scores: relief (mean [SD] 1.6 [0.7] vs 2.2 [0.6]; P = .047) and scar contracture (mean [SD] 1.3 [0.5] vs 2.5 [1.0]; P = .011). Conclusion. This study proves the feasibility of exploring the effects of MAT niche grafting following NMSC excision on healing time and specific parameters of scarring, including scar relief and scar contracture.

Vitreoretinal surgical treatment is indicated for diabetic macular edema (DME) in combination with vitreomacular interface abnormalities. Peeling of the retinal internal limiting membrane (ILM) is often used as part of the treatment. Tight adhesion of the posterior hyaloid membrane and the ILM may be the cause of the intraoperative retinal tractions development. Purpose. To assess the prevalence and impact of transient peeling-associated traction (tPAT) on the results and incidence of complications of surgical treatment of DME using ILM-peeling. Material and methods. As part of the study, a group of 40 patients was divided into 2 comparable subgroups according to the presence of tPAT (1st group — with tPAT, 2nd group — without tPAT). Patients in both groups received surgical treatment — three-port 27 Ga vitrectomy with ILM-peeling in a rounded area with a diameter of up to 2 DD centered on the fovea. ILM-peeling was performed using intraoperative tomographic control (optical coherence tomography). Results. In both groups, anatomical improvement was noted in the form of a decrease in foveal retinal thickness. At the same time, in 1st group there was no improvement in visual acuity, while in 2nd group its statistically significant increase was revealed. The presence of tPAT is associated with a higher incidence of postoperative neurodegenerative changes development of long-term follow-up period — disorganization of retinal inner layers and the formation of lamellar breaks in the fovea. According to correlation analysis, tPAT negatively affects the final value of visual acuity. Conclusion. It has been established that tPAT is a predictor of lower postoperative visual acuity, and is also a risk factor for retinal neurodegenerative changes in the long-term follow-up period. It is promising to evaluate the prevalence of tPAT in larger studies, reveal predictors of tPAT development and measures for their intraoperative prevention.

Purpose. To study the structural changes in the retinal layers after peeling of the internal limiting membrane (ILM) during surgery for idiopathic epiretinal fibrosis (iERF). Material and methods. The study included 69 patients (69 eyes) with iERF. A retrospective study was conducted with the study of documentation on the basis of the Center of Ophthalmology of the N.I. Pirogov NMHC from the period from 2021 to 2023. Results. The average thickness of the retina in the inner ring decreased from 420.2 ± 55.7 to 361.5 ± 26.8 microns. The total thickness of the retina significantly decreased in both the nasal and temporal internal fields after surgery. Conclusions. In the present study, thickening of the nasal parafoveal zone and thinning of the temporal inner layers of the retina were observed, which is reflected by various anatomical changes caused by peeling of the ILM. Analysis of the thickness of each layer and sector of the retina revealed various changes in the structures. Keywords: internal limiting membrane, idiopathic epiretinal fibrosis, retina

According to the literature, a pattern of increased activation of VEGF growth factors and a decrease in the level of BDNF in blood serum in the early stages of DR was revealed, which is a good diagnostic marker for detecting DR in the early stages. Purpose. To study the indicators of biomarkers (BDNF and VEGF) in the blood serum and features of retinal microcirculation in patients with type 2 diabetes in the absence of clinical signs and varying degrees of severity of DR and to determine their diagnostic and prognostic value. Material and methods. A clinical study was conducted among 252 people (n = 504), of which 168 patients with type 2 diabetes and 84 healthy individuals, the average age of which was 57.6 ± 7.8 years old, of which 52.6 % were men, 47,4 % women. Results and conclusion. As a result of the study, it was proved that a mild BDNF deficiency in the SC less than 0.62 ng/ml indicates general DR, and a BDNF level < 0.22 ng/ml indicates the development of PDR and/or diabetic macular ischemia (DMA).

Published: June 2024

The article presents the study results of 64 patients with suspicious (progressive) nevi (n = 42) and initial choroid melanomas (n = 22, of which n = 3 had anamnesis of choroid nevus). Ultrasound examination, digital photoregistration of the fundus and OCT were done for all patients. According to the OCT data it was possible to identify diagnostic criteria that help distinguish of suspicious nevi including those with a high risk of malignant transformation from initial choroid melanomas. First of all these are the preservation of the Bruch membrane and the presence of druses. While malignant transformation of suspicious nevi was characterized by shape asymmetry of the enlarged “choroidal complex”, dilation of large choroidal vessels around the nevus, the presence of RPE detachment and the presence of hyperreflective intraretinal inclusions. Criteria of initial choroid melanomas were violation of the integrity of the Bruch membrane, rounded cavities in the inner layers of the choroid, deposits at the level of RPE, edema and/or rupture of the photoreceptor layer.

Purpose. To present modern literature data on the main aspects of refractive lenticular extraction technology. Material and methods. To perform the review, the search for literature sources on PubMed abstract databases was analyzed using the keywords “keratorefractive surgery”, “corneal lenticular”, “femtosecond laser” and data from Russian publications on the topic of the article for the period up to and including 2023. Results. According to the literature data, the strengths and weaknesses of the implementation of each of the existing technologies of keratorefractive surgery have been studied, and the postulates of choosing the optimal method for correcting ametropia have been formulated individually for each patient. Conclusion. Today, keratorefractive surgery is a high-tech industry in ophthalmology and provides a predictable, high-precision and stable refractive result in patients with a wide range of refractive disorders. The analysis of accumulated scientific and clinical experience has shown that one of the most pathogenetically oriented technologies in keratorefractive surgery, minimally affecting the reduction of the biomechanical properties of the cornea, not inducing dry eye syndrome, providing a highly predictable postoperative result in the correction of myopia and myopic astigmatism is refractive lenticular extraction, opening a new era in laser vision correction.

Purpose. To study the effectiveness of early surgical rehabilitation of patients with openglobe injury type C. Material and methods. The clinical effectiveness of the proposed tactics was studied in 103 eyes with open-globe injury (OGI) type C. Associated traumatic complications included traumatic cataract of varying intensity (55.3 %), peripheral retinal tears (52.4 %), partial hemophthalmos (73.8 %) and traumatic retinal detachment (35.9 %). Depending on the timing of IOL implantation, patients were divided into 2 groups. In the main group (28 eyes), IOL implantation was carried out within a period of 24 hours to 3 days or in the volume of primary surgical treatment (PST), while in the comparison group (29 eyes) delayed IOL implantation was performed for 1–3 months. after vitreoretinal surgery. Results. In both groups, anatomical reattachment of the retina was achieved, an increase in visual functions was established with restoration of peripheral and improvement of central vision, regardless of the timing of IOL implantation, while BCVA after surgery in the main group ranged from 0.05 to 0.3 (0.2 ± 0.05), while in the comparison group BCVA was 0.15 ± 0.05 (from 0.05 to 0.2) respectively. Conclusion The use of the proposed tactics for early surgical rehabilitation of patients with open eye trauma with the presence of an intraocular foreign body (IOFB) can increase the effectiveness of treatment, reduce the number of stages of surgical intervention, improve clinical and functional results and increase their rehabilitation effect.

Purpose. To evaluate the efficacy of second-stage phacoemulsification (PE) of complicated initial cataract after vitreoretinal surgery (VRS) in patients with advanced proliferative diabetic retinopathy (PDR). Material and methods. 216 patients with PDR and complicated initial cataract who underwent surgery were included. These patients were divided into four groups according to their management. In the group I patients were subjected to a two-step surgical procedure: VRS with silicone oil tamponade was performed as the first step, followed by the second step — PE+IOL implantation + silicone oil removal. In the group II PE was performed simultaneously with VRS and silicone oil tamponade. The second step differed in the removal of silicone oil from the vitreous cavity. In the group III patients were subjected to a two-step surgical procedure: VRS with gas tamponade performed as the first step in their treatment; followed by the second step, PE and the IOL implantation. In the group IV PE performed simultaneously with VRS with gas tamponade. Results. Patients in subgroup I and group III had better functional results than those in subgroup II and group IV, respectively (p < 0,001). The subgroup IIa (n = 9; 14.5 %) showed higher incidence of NVG than the subgroup Ia (n = 2; 3.2 %), p = 0.027. There also was a higher rate of NVG in group IV (n = 6; 19,3 %) compared to group III (n = 1; 3,1 %), p = 0,04. Conclusion. Phacoemulsification of initial cataract at the second stage after VRS in patients with advanced PDR provides a sparing approach to surgical treatment in this category of patients and allows to improve anatomical and functional results of VRS. In addition, it contributes to reduction of number and severity of postoperative complications. Keywords: proliferative diabetic retinopathy; vitreoretinal surgery; phacoemulsification

In the last few years, autologous retina transplantation has been repeatedly mentioned in foreign literature as a new method of treating primary through and recurrent refractory macular holes of large diameter. Purpose. To discuss the results of a clinical case of autologous retina transplantation in a patient with recurrent macular hole. Material and methods. A patient with recurrent macular hole, partial optic nerve atrophy, operated on in 2017, was under observation. There is a MH with a diameter of 1600 microns on the OCT of the macular zone. The course of the operation. At the first stage, the remains of the anterior vitreous were removed. Next, the vitreous chamber was tamponaded with perfluorodecalin. The retinal flap was cut out in the lower part of the middle periphery. With the help of endothermocoagulation, the flap is delimited and mobilized. Next, the flap was dislocated to the macular area. The MH is closed by the dislocated retina. A fringing laser coagulation of the retina was performed around the removed part of it. After that, the patient is left lying on his back on the operating table for 1 hour. After a double examination after 30 minutes and 1 hour, after making sure that the flap is in the correct position, the tamponade of the glassy chamber of perfluorodecalin, the trocars are removed, stitches are applied. After 4 days, perfluorodecalin was replaced with silicone oil. Results. On the first day, according to the results of OCT, the macular opening is closed, the thickness of the retina in the central zone is 619 microns. The corrected visual acuity remained at the same level. 2 weeks after surgery, the retinal thickness is 505 microns, the corrected visual acuity is 0.02, the flap is fixed, the macular rupture is closed. 1.5 months after surgery, after removal of silicone oil, visual acuity was without correction, retinal thickness. Conclusion. The autologous retina transplantation method can be used in the treatment of recurrent macular hole. Keywords: transplantation, autologous retina, macular hole

The search for new materials can be laborious and expensive. Given the challenges that mankind faces today concerning the climate change crisis, the need to accelerate materials discovery for applications like water-splitting could be very relevant for a renewable economy. In this work, we introduce a computational framework to predict the activity of oxygen evolution reaction (OER) catalysts, in order to accelerate the discovery of materials that can facilitate water splitting. We use this framework to screen 6155 ternary-phase spinel oxides and have isolated 33 candidates which are predicted to have potentially high OER activity. We have also trained a machine learning model to predict the binding energies of the *O, *OH and *OOH intermediates calculated within this workflow to gain a deeper understanding of the relationship between electronic structure descriptors and OER activity. Out of the 33 candidates predicted to have high OER activity, we have synthesized three compounds and characterized them using linear sweep voltammetry to gauge their performance in OER. From these three catalyst materials, we have identified a new material, Co2.5Ga0.5O4, that is competitive with benchmark OER catalysts in the literature with a low overpotential of 220mV at 10mAcm-2 and a Tafel slope at 56.0 mV dec-1. Given the vast size of chemical space as well as the success of this technique to date, we believe that further application of this computational framework based on the high-throughput virtual screening of materials can lead to the discovery of additional novel, high-performing OER catalysts.

Published: June 2024

Single-particle photoluminescence (PL) measurements have been extensively utilized to investigate the charge carrier dynamics and recombination processes in quantum dots (QDs). Among these techniques, single dot blinking studies are effective for probing relatively slower processes with timescales >10 milliseconds (ms), whereas fluorescence correlation spectroscopy (FCS) studies are suited for recording faster processes with timescales typically <1 ms. In this study, we utilized scanning FCS (sFCS) to bridge the ms gap, thereby enabling the tracking of carrier dynamics across an extended temporal window ranging from microsecond (µs) to subsecond. We compared our sFCS data recorded on surface-immobilized twelve-faceted CsPbBr3 dodecahedron perovskite nanocrystals (d-PNCs) with that of the solution phase FCS study, revealing qualitatively similar yet quantitatively different results. Latter is primarily attributed to the significantly varying immediate environments of PNCs in these two techniques, as well as the different temporal lengths of the observation windows available for the recording of carrier dynamics. The most intriguing finding of our study lies in the non-converging behavior of the blinking timescale (τR) even in sFCS, despite this technique providing an extended temporal window size (≤440 ms) for studying carrier dynamics. We attribute this observation to PL blinking following power law statistics. The consequence of power law blinking includes the mean ON/OFF duration of blinking persuasive to the experimental integration time, making blinking occur across all timescales.
From femtoseconds to minutes: spectroscopic study of optically-induced thermal diffusion in aqueous solution of rhodamine B
Authors: NOME RENE , H. OLIVEIRA ALEXANDRE
Published: June 2024

Given that nonequilibrium molecular motion in thermal gradients is influenced by both solute and solvent, the application of spectroscopic methods that probe each component in a binary mixture can provide insights into the molecular mechanisms of thermal diffusion for a large class of systems. In the present work, we use an all-optical setup whereby near-infrared excitation leads to a steady-state thermal gradient in solution, followed by characterization of the nonequilibrium system with electronic spectroscopy, imaging and intensity. Using rhodamine B in water as a case study, we perform measurements as a function of solute concentration, temperature, wavelength, time, near-infrared laser power, visible excitation wavelength, and isotope effect. The results are complemented with non-equilibrium molecular dynamics simulations and analysis of infrared spectra and heat diffusion and stochastic dynamics simulations of the coupled Brownian/spectroscopic non-equilibrium dynamics. Overall, the results presented here exemplifies how spectroscopic probing of solute and solvent can be useful for understanding molecular mechanisms of optically-induced thermal diffusion in aqueous solution of rhodamine B.

Published: June 2024

Polarizable continuum solvation models are popular in both, quantum chemistry and in biophysics, though typically with different requirements for the numerical methods. However, the recent trend of multiscale modeling can be expected to blur field-specific differences. In this regard, numerical methods based on domain decomposition (dd) have been demonstrated to be sufficiently flexible to be applied all across these levels of theory while remaining systematically accurate and efficient. In this contribution, we present ddX, an open-source implementation of dd-methods for various solvation models, which features a uniform interface with classical as well as quantum descriptions of the solute, or any hybrid versions thereof. We explain the key concepts of the library design and its API, and demonstrate the use of ddX for integrating into standard chemistry packages. Numerical tests illustrate the performance of ddX and its interfaces.

Published: June 2024

Wearable electronic textiles, also known as e-textiles, have surfaced as a promising means of seamless and unobstructed incorporation of electronic health monitoring gadgets into our daily routines. Yet, creating high-performance and flexible energy storage solutions still presents a notable hurdle in advancing these technologies. Nevertheless, creating efficient, adaptable, and expandable energy storage solutions continues to pose a noteworthy obstacle in powering these devices. This study demonstrates a facile strategy to design and fabricate MOF-based smart wearable e-textiles for all-solid-state textile supercapacitors. We report the fabrication of highly flexible and washable e-textiles by exploiting screen printing, pad-dry coating and inkjet print technology utilising a standalone MOF. The fabricated e-textiles were used as electrodes for an all-solid-state textile supercapacitor. The high areal capacitance of ~221.51 mF cm-2, ~359.4 mF cm-2 and ~353.5 mF cm-2 were achieved at a scan rate of 1 mVs-1 for screen print, pad-dry coating and inkjet printing technology respectively. With high energy densities of ~123.06 µWh cm−2 (screen print), ~199.66 µWh cm−2 (coating) and ~196.39 µWh cm−2 (inkjet print) and very high-power densities ~55 377.5 µW cm−2 (screen print) ~55 291.54 µW cm−2 (coating) ~54 385.38 µW cm−2 (inkjet print), the supercapacitors also showed outstanding capacitance retention (⁓97.4-97.9%) after 1 000 cycles. Our findings successfully demonstrate the potential of MOF-based smart textiles for wearable electronics applications, especially opening a new pathway for high-performance textile-based energy storage solutions.
Size-dependent Magneto-catalytic Effect in Ferromagnetic Nanoparticles
Authors: Xu Gaomou , Wang Tao
Published: June 2024

The magneto-catalytic effect (MCE) indicates that the paramagnetic (PM) state of a ferromagnet could exhibit a distinct chemical reactivity from its ferromagnetic (FM) ground state. Recently, we have system-atically investigated the MCE on cobalt-catalyzed ammonia synthesis by ab initio spin dynamics. Howev-er, our model is still in the scope of ideal single-crystal facets rather than realistic nanoparticles (NPs). In this work, we employ an atomistic model using a nearest-neighbor Heisenberg Hamiltonian exchange to computationally study the size dependence of the MCE at nanoscale particles. As a result, the optimal reac-tion temperature for cobalt NPs to achieve the Sabatier optimal activity for ammonia synthesis can be de-creased by 300 K at an adequate particle size compared with that derived from bulk. We believe our find-ings could bridge the gap between the properties of bulk phase transition and the localized chemical reac-tions at heterogeneous interfaces.

O lugar da criança no pensamento freiriano: um convite ao diálogo
Authors: Carvalho Lilian Maria , Amorim Lívia de Miranda
Published: June 2024

Esse texto tem por objetivo tecer reflexões e contribuições do pensamento freiriano as questões ligadas a criança, a infância e a Educação Infantil. Para isso, recorremos a um breve relato da trajetória da Educação Infantil no Brasil, bem como as políticas públicas no atendimento das crianças em Creches e pré-escolas como base de interlocução aos pressupostos de Paulo Freire. O processo metodológico desenvolvido considerou o método categorial de conteúdo em Bardin (1977). A partir de uma incursão nas obras de Freire, construímos o referencial teórico, onde são apresentadas categorias, tecendo as compreensões subjacentes à concepção da criança protagonista e de uma infância humanizada, em que a educação não é apenas preparar para viver, mas constantes leituras de mundo.

Iniciação ao método científico com ensaios de determinação de coeficientes de atrito
Authors: Batista de Lima Araújo Felipe , Barbieri Paulo Fernando
Published: June 2024

Uma visão singela do que é uma teoria científica é apresentada através do pensamento de Karl R. Popper, aliada ao método científico experimental ao modo galileano e sua realização, finalizado com uma análise crítica e quantitativa. Haja vista que a prática normalmente é em escrever sobre um ou outro assunto em periódicos ou círculos específicos de discussão, isto é, sobre o pensamento em si ou sobre um experimento dedicado. Assim, aqui é apresentada uma proposta em que o pensamento sobre ciência se junta a um modo de fazê-la numa forma didática, fornecendo material de apoio a estudantes e professores, tendo como desenvolvimento experimentos de determinação do coeficiente de atrito entre superfícies planas. A intuição é combatida pela realização dos experimentos com ênfase a atenção sobre os resultados para não induzir a conclusões falsas, principalmente estudantes iniciantes. Os resultados indicam que gráficos de dispersão, amplamente usados para definir linhas de tendência, nem sempre devem ser apresentados como resultados únicos, carecendo de outras análises para não induzir a equívocos.
