Published: May 2022

Background. Spinal muscular atrophy with respiratory distress type 1 (SMARD1) is a very rare autosomal recessive disorder caused by mutations in the immunoglobulin μ-binding protein-2 (IGHMBP2) gene on chromosome 11q13.2-q13.4. The initial symptoms of patients with SMARD1 are respiratory distress and distal muscle weakness manifesting in the infantile period due to progressive degeneration of α-motor neurons. Preterm birth, intrauterine growth retardation, feet deformities, sensory and autonomic neuropathy are other main features.
Case. Herein, we report the characteristics of a 6-year-old Turkish girl with a diagnosis of SMARD1 confirmed by homozygous c.1738G > A (p.Val580Ile) missense IGHMBP2 variant. She had unusual features such as vocal cord paralysis, nystagmus, and lack of congenital foot deformities besides typical findings including hypotonia, respiratory distress, and diaphragmatic weakness in the early infantile period. Epileptic seizures, cognitive impairment, and brain magnetic resonance imaging (MRI) abnormalities were other, unexpected, features which developed during the course of the disorder possibly due to several hypoxic episodes.
Conclusions. SMARD1 should be kept in mind in hypotonic infants with diaphragmatic weakness and respiratory failure during the early infantile period, even in the presence of unexpected findings including vocal cord paralysis, nystagmus, epileptic seizures, and brain MRI abnormalities.

Background. Vaccines, which make it possible to be protected from many life-threatening infectious diseases, have been used safely and effectively for years. Most vaccines used today contain a variety of adjuvants and exogenous proteins. Severe reactions, in addition to transient and self-limiting mild reactions, mostly caused by these components, have been reported. The effects of vaccine adjuvants on the pathogenesis of immunemediated diseases are still under investigation. The syndrome called Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) has been defined in the literature.
Case. We found a novel mutation of autoinflammatory diseases in the genetic analysis of our patient. The patient developed symptoms of prolonged fever, rash, arthritis and serositis after multicomponent serogroup B meningococcal (Bexsero®) vaccination, without a previously known rheumatic disease. In the presence of clinical findings in our patient, the diagnostic criteria of ASIA syndrome were met.
Conclusion. To the best of our knowledge, this is the first case report of a patient diagnosed with the autoinflammatory disease with a novel mutation after Bexsero® vaccination. We consider that genetic examinations will be useful in patients with a systemic vaccine reaction in the presence of ASIA when diagnostic criteria are met.
Evaluation of nocturnal blood pressure changes and urinary electrolyte excretion in children with enuresis
Authors: Emeksiz Zeynep Şengül , Ağras Pınar Işık , Emeksiz Serhat , Dallar Yıldız Bilge
Published: May 2022

Background. Monosymptomatic nocturnal enuresis (MNE) is defined as involuntary nighttime urination of children over five years of age without any congenital or acquired defect in the central nervous system. Many factors, mainly nocturnal polyuria, sleep disorders, decreased bladder capacity, and bladder dysfunctions play a role in the etiology of MNE.
Methods. Eighty-three children diagnosed with MNE were included in the study. Complete blood cell count, blood biochemistry, renin, and aldosterone levels of all children were obtained. Twenty-four-hour urine samples were collected separately daytime and nighttime and urinary electrolytes were evaluated. Also, 24-hour ambulatory blood pressure monitoring (ABPM) was performed for each patient. The results were evaluated by comparing both enuretic children vs. control group and enuretic children with polyuria vs. without polyuria.
Results. When we compared the enuretic children and the control group in terms of urinary electrolytes, the fractional excretion of sodium (FENa) and fractional excretion of potassium (FEK) values of the enuretic group were higher than the control. The evaluation of the 24-hour ABPM findings revealed no significant difference in terms of the mean arterial pressure (MAP) and diastolic blood pressure (DBP) during the daytime and nighttime measurements. The daytime systolic blood pressure (SBP), however, was significantly lower in the enuretic group. When enuretic children with and without polyuria and the control group were compared, the nighttime, FENa, FEK, as well as nighttime urinary excretion of calcium and protein were significantly higher in enuretic children with polyuria. No difference was detected on the MAP, SBP, or DBP values.
Conclusions. In conclusion, the nighttime urinary solute excretion of enuretic children was found to be higher and this condition may especially be associated with pathogenesis of nighttime polyuria. In enuretic children, nighttime blood pressure changes were not influential in the etiopathogenesis in all patient groups and multiple mechanisms may play a role in the pathogenesis of enuresis.

Published: May 2022

Background. Curarino syndrome is a rare and complex anomaly with the triad of anorectal malformation, presacral mass and sacral bone deformation. The most common cause of the presacral mass is meningioma, but teratoma is the diagnosis in about one-third of the cases. Malignant transformation of teratoma in the form of carcinoma, rhabdomyosarcoma and leukemia have previously been reported on rare occasions.
Case. A 19 month-old-girl was referred with a presacral mass of 29mm x 23mm x 24mm. She was diagnosed as Currarino syndrome. The presacral mass was surgically resected and pathological examination revealed a foci of primitive neurectodermal tumor.
Conclusions. This is the first case of Currarino syndrome with a primitive neuroectodermal tumor (PNET) foci in the presacral mass. Considering the risk of malignant transformation, the accurate pathological examination is important for complete systemic evaluation and treatment plan in these children.

Published: May 2022

Background. This study aimed to evaluate the nutritional status and body composition in children with cystic fibrosis (CF), in accordance with the new nutritional targets defined by European Society for Clinical Nutrition and Metabolism (ESPEN), the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and the European Cystic Fibrosis Society (ECFS) 2016.
Methods. In this cross-sectional study, data were collected prospectively in a single centre. A record was made for a total of 95 patients with CF of clinical data. Anthropometric data were evaluated using the World Health Organization growth standards. The bone mineral density (BMD) z-score was adjusted for height by measuring dual-energy X-ray absorptiometry (DXA). The speed of sound z-score values were measured with quantitative ultrasound (QUS).
Results. The nutritional status was normal in 37.9% of patients aged < 2 years and 33.3% of patients aged 2-18 years. When the DXA BMD z-score values were corrected for height, it was determined that the BMD deficit was less. The calcaneus QUS SOS z-score mean value was lower than the mean height for age z-score adjusted BMD (BMDHAZ).
Conclusions. The malnutrition rates of CF patients were higher than the rates previously reported in literature. As there are insufficient nutritional data in Turkey, there is a need for multi-centre studies to determine the frequency of malnutrition according to the new classifications. It is clear that QUS measurements cannot replace DXA in the diagnosis of osteopenic bone disease. However, when low values are determined with QUS as the first recommended measurement in the screening of bone status, it can be considered appropriate to confirm the status with DXA.

Tendencias de la narrativa chiapaneca actual
Authors: Mijangos Alejandro , Martínez Torres José
Published: May 2022

Alejandro Mijangos y José Martínez Torres nos hablan acerca de Balún Canán (1957), de Rosario Castellanos, la cual presenta la lucha de clases y de razas entre blancos e indígenas, en donde, comentan, se observa una imparcialidad que es inusual incluso en la literatura misma. Dicho tema, por ejemplo, se muestra que ha sido una constante en la narrativa de la región, ya que, como alunden los autores, este tópico fue tocado por Flavio A. Paniagua (1844-1911), quien aludía a los indígenas desde una postura conservadora a favor de los blancos.

El cuento en Chiapas (1913-2015), de Alejandro Aldana Sellschopp (comp.)
Authors: Escalante Katia
Published: May 2022

El escritor búlgaro Elias Canettu dice que, aunque en su hogar se hablaban muchos idiomas, sus padres se comunicaban en alemán entre ellos; cuando, de niño, el autor se ponía a escucharlos, creía que sus padres decían cosas maravillosas que solo se podían expresar en ese idioma. Elias Canetti no entendía alemán pero anhelaba entrar a ese universo lingüístico, un universo que cada lengua posee. En la antología El cuento en Chiapas (1913-2015) se puede ver y escuchar un universo lingüístico propio de ese estado, pues los cuentos que se reúnen allí son ventanas que permiten vislumbrar asuntos culturales propios  de lo que podríamos llamar lo chiapaneco.

OBSERVATORIO ACADÉMICO DEL ESPACIO PÚBLICO: CASO XALAPA, VER.
Authors: Hernández Bonilla Mauricio
Published: May 2022

La propuesta de un “observatorio del espacio público” es producto del proyecto “Políticas públicas y la transformación del espacio público en la ciudad contemporánea del siglo veintiuno”, proyecto auspiciado por el Consejo Nacional de Ciencia y Tecnología(CONACYT) del Fondo de Ciencia Básica 2012 (180749). Este proyecto, entre otros productos y metas científicas, propone la observación y registro sistemático de las condiciones actuales del espacio público en el contexto Veracruzano. De modo que, en coordinación con la Coordinación Universitaria de Observatorios (CUO) y el Cuerpo Académico “Entornos Sustentables” (UVER-285) de la Facultad de Arquitectura de Xalapa, ambos de la Universidad Veracruzana, iniciaron el monitoreo y análisis de las intervencionesrealizadas en los espacios públicos de la ciudad de Xalapa entre el año 2000 y 2015.Durante los primero años del siglo veintiuno se iniciaron acciones gubernamentales relacionadas con el espacio público para el rescate de espacios abiertos urbanos, que han significado estrategias para la recuperación del tejido social de los barrios en las ciudades mexicanas, todo de cara a la violencia e inseguridad prevaleciente en el país. De este manera, en este artículo se expone el trabajo sistemático realizado por profesores y alumnos resultado del análisis observacional de las condiciones socio-espaciales de diversos espacios públicos, que han sido intervenidos principalmente en el marco de las políticas y programas gubernamentales (tanto locales como nacionales) relacionados con la creación, mejoramiento y/o rehabilitación del espacio abierto público.
Corrientes superficiales dentro del corredor arrecifal del Suroeste del Golfo de México
Authors: Salas Monreal David
Published: May 2022

Frente a las costas del estado de Veracruz (México) se conoce la ubicación de grandes agrupaciones de arrecifes de coral conocidos como el “Parque Nacional Sistema Arrecifal Veracruzano”, el “Área de Protección de Flora y Fauna Sistema Arrecifal Lobos-Tuxpan” y el “Sistema Arrecifal de los Tuxtlas”, las cuales cuentan con numerosas estructuras individuales de más de 1 kilómetro de largo en su eje mayor. Estos grupos de arrecifes de coral se han estudiado desde un punto de vista multidisciplinario con la finalidad de encontrar una relación entre ellos. El reto actual sobre el corredor arrecifal del suroeste del Golfo de México es determinar desde las diferentes disciplinas cómo se da esta conectividad. Dado lo anterior en este estudio se usó el modelo “Regional Ocean Model System” (ROMS) para describir las corrientes marinas superficiales y estimar el tiempo de traslado de una larva o huevo de 5 mm entre los distintos sistemas arrecifales. Mediante los resultados obtenidos aquí se puede observar que la conectividad entre los tres sistemas arrecifales es clara durante la temporada de nortes, pero durante la temporada de suradas solo existe una conectividad entre los dos sistemas arrecifales del norte, dejando al Sistema Arrecifal de los Tuxtlas sin una conexión aparente con los otros dos sistemas.
El Campo Volcánico Xalapa: una revisión y análisis
Authors: Sieron Katrin , Carreto Peralta Fátima Paula , McLeod Oliver E. , Guilbaud Marie Noelle
Published: May 2022

El Campo Volcánico Xalapa (CVX) consta de 42 conos de escoria y al menos 2 volcanes escudos, cuyas edades varían entre 2 millones de años (M.a.) hasta 870 años (a) antes del presente (datos radiométricos publicados). Mediante la determinación de los parámetros morfométricos, se estimaron las edades relativas de los conos de escoria (tipo de volcán predominante en el CVX) aun no fechados. La densidad de los conos de escoria dentro del campo varia de 0 hasta 2 por km2. El uso de la función kernel permite identificar zonas con mayor densidad de volcanes al NW de Xalapa entre Acajete y Las Vigas de Ramírez (grupo La Joya) y al norte de Coacoatzintla, mientras zonas con concentraciones menores están localizadas alrededor de Pacho Viejo y al norte de Ayahualulco. Aunque el Campo Volcánico Xalapa no es el campo con mayor número de edificios del Cinturón Volcánico Trans-Mexicano (CVTM), ni el más denso; sin embargo se debe crear consciencia de que puede dar lugar al nacimiento de un nuevo volcán en el futuro. Un monitoreo sería deseable.Palabras clave: Campo volcánico Xalapa; conos de escoria; volcanes escudo; volcanes; parámetros morfométricosAbstractThe Xalapa Monogenetic Volca­nic Field (XMVF) defines a group of 42 scoria cones and at least two lava shields that erupted between 2 million and 870 years before pre­sent (according to published radiometric data). In this study, we measured the morphometric parameters of XMVF scoria cones in order to assign relative ages to undated volcanic cen­ters. The density of vents within the limits of the volcanic field (estimated by using spatial point density analysis) and found to vary from 0 to a maximum of 2 volcanoes per square ki­lometer. Kernel density function analysis re­vealed that the highest concentrations of vol­canoes occur NW of Xalapa between Acajete and Las Vigas de Ramirez (La Joya group), and N of Coacoatzintla, while lesser concentra­tions occur around Pacho Viejo and to the N of Ayahualulco. Although the XMVF is relatively small and has a low vent-density compared to other volcanic fields in the Trans-Mexican Vol­canic Belt, a greater level of public awareness and hazard monitoring, is required in prepara­tion for the next XMVF eruption.Keywords: Xalapa Monogenetic Volca­nic Field; scoria cones; lava shields; volcanoes; morphometric parameters

O piolho da espécie Felicola subrostratus é um inseto mastigador responsável por causar a pediculose em felinos e, apesar de ser cosmopolita, tem sua ocorrência pouco descrita na rotina clínica. A transmissão ocorre através do contato direto entre os animais ou por fômites contaminados. Os gatos parasitados podem ser assintomáticos quando em baixa parasitemia, porém em altas infestações podem apresentar prurido, alopecia, dermatites e possibilitar a ocorrência de infecções secundárias. O objetivo desse trabalho foi relatar a infestação por piolhos da espécie Felicola subrostratus em um felino domiciliado no município de Parnaíba, Piauí. O animal era um macho castrado, de 2 anos de idade, sem raça definida (SRD), que foi atendido em uma clínica veterinária da cidade, apresentando como queixa principal uma dermatite por lambedura no membro posterior direito, além de prurido, alopecia, apatia, diminuição de apetite e perda de peso. No exame físico, observou-se a dermatite no membro, sendo realizado raspado cutâneo e coleta de pelos da região, verificando a presença de ectoparasitos. Estes insetos foram colocados em recipientes com álcool 70ºGL e enviados ao Laboratório de Parasitologia da Universidade Federal do Piauí, que por meio da morfologia revelou ser piolhos da espécie Felicola subrostratus, confirmando o diagnóstico primário de pediculose felina, sendo essencial um diagnóstico precoce para direcionar a um tratamento adequado.
Elevada prevalência de depressão em pacientes de um ambulatório de referência em fibromialgia

Published: May 2022

Introdução: Fibromialgia (FM) é uma síndrome dolorosa crônica e, frequentemente ocorre concomitantemente com depressão, mas as taxas dessa co-ocorrência são inconsistentes entre os estudos, com grande variabilidade. Objetivo: Investigar e comparar a prevalência de depressão em pacientes do ambulatório de fibromialgia do Conjunto Hospitalar de Sorocaba (FM) e em pacientes sem fibromialgia atendidas na unidade básica de saúde (SFM). Assim como avaliar idade, índice socioeconômico, emprego e uso de serviços de saúde mental nessas populações. Método: Estudo transversal onde foram avaliadas 35 mulheres com FM e 27 SFM. Para avaliação da presença de depressão utilizamos o Inventário de Depressão de Beck e para as demais variáveis utilizamos um questionário de dados sociodemográficos. Como a amostra com FM foi majoritariamente composta por mulheres, optamos por excluir os homens das análises. Comparamos os resultados das amostras de acordo com a origem e posteriormente avaliamos apenas a amostra com fibromialgia, quando realizamos uma análise de correlação exploratória e subsequentemente dividimos em FM com depressão e FM sem depressão para explorar as possíveis diferenças entre as variáveis. Resultados: A prevalência de depressão observada no período do estudo foi de 65,7% na amostra FM e de 29,6% na SFM. As pacientes com FM eram significativamente mais velhas (53,9 anos e 40 anos), com maior proporção de mulheres aposentadas e do lar, com menor índice socioeconômico e com maior uso de serviço de saúde mental, quando comparadas às SFM. Conclusão: Dada a alta prevalência de transtorno depressivo em nosso estudo, podemos sugerir que todos os pacientes diagnosticados com fibromialgia deveriam ser sistematicamente investigados quanto à presença de depressão na tentativa de diagnóstico e intervenções precoces.

Synopsis

Equitable care for low back pain (LBP) is key to ensuring the value and sustainability of services delivered by physical therapists. In this Viewpoint, we discuss how social determinants of health, implicit provider biases, structural characteristics of the health care system, and health care policies contribute to disparate care for many individuals with LBP. We aim to increase awareness of equity as a key component of value in physical therapy and highlight steps physical therapists can take to improve equitable LBP care. This “call to action” underscores the need to study, demonstrate, and advance equitable care for LBP by physical therapists to improve outcomes for patients and ensure the growth and sustainability of the physical therapy profession.

Purpose. The Tartas-1 complex of burials, ritual places and settlement takes a special place. Due to the excavation method of full opening of the site area, today the followings are explored and fully studied: an area of more than 36,000 m2 , 802 burials and related structures in the form of ditches, 1745 pits of various orientations, ritual complexes of various eras and cultures, including an early Neolithic settlement. The settlement is represented by two household structures (dwellings) and a complex of storage pits for fish, dated to the 7th millennium BC and attributed to the Baraba culture of the early Neolithic. The purpose of this article is to present the characteristics and dating of the new fish pit studied in the 2021 field season in the context of the known data. Results. The fish pits excavation method, mainly based on the enclosing soil-fill study, is proposed. The stratigraphy characteristic and the parameters of the pit are presented. A feature of the absence of any animal skeleton (dog, hare, fox, wolverine, etc.) placed in the pit as a sacrificial offering is noted. The date of (MAMS 53633) BP 7714 ± 29 Cal BCE 1 σ (Intcal 20) 6588–6502 2σ (Intcal 20) 6636–6469, obtained from an animal horn tool (tur?) found in the pit at the depth of 2.36 m below bedrock, is presented. The analysis was carried out at the Curt-Engelhom-Centre for Archaeometry (Germany). Calibration of the date by 1σ and 2σ demonstrates a complete correlation with the already available dates from the pit samples. The period of the Baraba culture's existence – the 7th millennium BC – is confirmed. Conclusion. The manifestation of economic practice among the bearers of the early Neolithic Baraba culture is a demonstration of innovation. It consists of the improvements on the appropriating economy with the increasing role of water resources, and the transition to a less mobile way of life, found among the ancient Siberian population at the end of the 8th – 6 th millennium BC. Pit no. 1741 also existed in this time period.

Recently, Indonesia will lead to gas deficits since the increase in domestic gas demand in 2040. The increasing need for energy sources and the decreasing available reserves have encouraged oil and gas companies to explore and manage marginal reservoirs such as sour gas environment to maintain the balance of energy supply and demand. The gap in gas supply-demand will decrease by 20% due to the supply of Natuna Gas Field, as the example of potential sour gas environment (Batubara, 2015). Thus, it is very relevant to develop this potential source immediately.

Also, sour gas field approximately shares 40% of Indonesia’s total proven gas reserve with an estimated OGIP of around 222 TSCF, with 75% of gas recovery. Unfortunately, sour gas environment cannot be produced economically since the it has high carbon dioxide (CO2) and hydrogen sulfide (H2S) content, which are toxic and corrosive.

The X sour reserves contain 32% carbon dioxide (CO2) and 7072 ppm H2S with fluid gravity of 42 API. This discretionary source of CO2 was recently brought into production from one well with depth of 8400 ft. The well was perforated in a limited interval of 7100 until 7700 ft. The harsh environment presented many challenges to completion design. Unique equipment and material selection were required.

This study aims to determine the reservoir fluids and production performance also predict the corrosivity of CO2 dissolved in the natural gas. With the simulation and prediction, it can be obtained the proper material and equipment selection based on the sour service needed. As a result, the wet gas reservoir of X field can produce optimum rate of 19.1063 MMSCFD. For completion design, Nickel Alloy SM2535 or SM2242 is needed as there will be damage in form of corrosion and pitting.

Le partage, sur Internet, est polysémique.

Les modèles économiques de ces plateformes supportent l’absence d’exclusivité sur les droits de propriété intellectuelle et les licences libres qui perdent alors leur puissance politique. Nous explorons la manière dont le partage est devenu le moteur du renouvellement d’une ressource dont la valorisation s’apparente aux modèles extractivistes et explorons la piste d’un extractivisme dans le domaine numérique.
Unravelling the Binding Affinity and Selectivity of Molybdenum (II) Phenanthroline Complexes with DNA G-Quadruplexes by Using Linear-Scaling DFT studies. The Important Role of Ancillary Ligands

We have used near linear-scaling density functional theory (LS-DFT) methods including dispersion, for the first time, to study the interaction of two isomers, equatorial (Eq) and axial (Ax), of the [Mo(η3- C3H5)Br(CO)2(phen)] metal complex with the DNA G-quadruplexes (GQ) to gain insight on its cytoxicity. The LMKLL/DZDP level of calculation, which includes van der Waals contributions, with the SIESTA software was used to treat by means of first-principles computations the whole biological studied model system with 1000 atoms. Computed formation energies and the energy decomposition analysis (EDA) point to systems containing the Eq isomer as the most stable. However, when solvent effects are taken into account the systems containing the Ax isomer are the most stable. This Ax isomer was found interacting by means of end-stacking with the GQ and surprisingly totally inside the non-canonical secondary structure, where all the ligands of the metal complex produce several weak interactions with the DNA structure. On the other hand, the Eq isomer prefers to interact from outside by means of intercalation in which the ancillary ligands have also some role in the interaction. Nevertheless, some stable system was found for the Eq isomer in which the Br halogen atom was the main link through which the interaction is produced between the metal complex and DNA bases. For this case, the weak interactions produced by the ancillary ligands are very important, whereas no π − π stacking is found through the phen ligand. Such features and comparison with the results regarding the interaction of [Mo(η3-C3H5)Br(CO)2(phen)] metal complex with duplex DNA suggest that the [Mo(η3-C3H5)Br(CO)2(phen)] complex would have higher affinity and eventual selectivity for non-canonical DNA GQ structures.

Developing a cost-effective processing approach for generating fuel-precursor chemicals such as 5-hydroxymethylfurfural (HMF) and furfural has been researched to a great deal over the last few years. Typically, these chemicals are produced using a different carbohydrate source, like xylose for furfural and glucose for HMF. Herein, we report the significant formation of these furan chemicals using glucose over the fine-tuned Fe2+@SO3-CD nanocomposite. The catalyst exhibiting two different acidic sites, namely Lewis and Brønsted, developed by the iron (II) metal and sulfonate groups, respectively, offered a synergistic effect on the glucose decomposition into furans. Mechanistically, the iron (II) Lewis metal acid sites play a vital role in the significant formation of furfural. In addition, the biphasic system comprising THF/H2O influenced a selective HMF and furfural formations, achieving as high as 85% HMF (94% selectivity) in 1:2 THF/H2O and 56% furfural (90% selectivity) in 1:1 THF/H2O. The recyclability study disclosed that the catalyst is effective for 4 recycles. The green metrics analysis of the solid acid catalysis suggested that setup is a greener method for furans production. Moreover, the catalysis reaction can be upscaled based on the use of cheaper precursors and a facile method of catalyst preparation.

MXenes are ultra-thin two-dimensional layered early-transition metal carbides and nitrides with potential applications in various emerging technologies, such as energy storage, water purification, and catalysis. MXenes are synthesized from the parent MAX phase with different etching agents (HF or fluoride salts with a strong acid) by selectively removing a more weakly bound crystalline layer of Al or Ga replaced by surface groups (-O, -F, -OH, etc.). Ti3C2Tx MXene synthesized by CoF2/HCl etching has layered heterogeneity due to intercalated Al3+ and Co2+ that act as pillars for interlayer spacings. This study investigates the impacts of etching environments on the compositional, interfacial, structural, and thermodynamic properties of Ti3C2Tx MXenes. Specifically, compared with HF/HCl etching, CoF2/HCl treatment leads to a Ti3C2Tx MXene with a broader distribution of interlayer distances, increased number of intercalated cations, and decreased degree of hydration. Moreover, we determine the enthalpies of formation at 25 °C (ΔHf,25°C) of Ti3C2Tx MXenes etched with CoF2/HCl, ΔHf,25°C = –1891.7 ± 35.7 kJ/mol Ti3C2, and etched with HF/HCl, ΔHf,25°C = –1978.2 ± 35.7 kJ/mol Ti3C2, using high-temperature oxidation drop calorimetry. These energetic data are discussed and compared with experimentally derived and computationally predicted values to elucidate the effects of intercalants and surface groups of MXenes. We find that MXenes with intercalated metal cations has a less exothermic ΔHf,25°C from an increase in the interlayer space and dimension heterogeneity and a decrease in the degree of hydration leading to reduced layer–layer van der Waals interactions and weakened hydration effects applied on the MXene layers. The outcomes of this study further our understanding of MXene’s energetic–structure–interfacial property relationships.

Published: May 2022

Chemical imaging of molecular decomposition processes at solid-liquid interfaces is a long-standing problem in achieving mechanistic understanding. Conventional analytical tools fail to meet this challenge due to the lack of required chemical sensitivity and specificity at the nanometer scale. In this work, we demonstrate that high-resolution hyperspectral tip-enhanced Raman spectroscopy (TERS) imaging can be a powerful analytical tool to study on-surface decomposition chemistry at the nanoscale. Specifically, we present a TERS based hyperspectral approach to visualize the on-surface decomposition process of a pyridine-4-thiol (4-PyS) self-assembled monolayer on atomically flat Au(111) surfaces under ambient conditions. Reactive intermediates involved in the degradation process are spectroscopically detected with 5 nm spatial resolution. With supporting density functional theory simulations, a key species could be assigned to the disulfide reaction intermediate. This work opens a new application area of studying on-surface decomposition chemistry and related dynamics quantitatively at solid-liquid interfaces with nanometer spatial resolution.
