DECOLONIALIDADE E ANTIRRACISMO NA FORMAÇÃO DE PROFESSORAS/ES: práticas de resistência negra
Authors: Pinheiro Patricia Magalhães , Beloni Josiane de Paula
Published: January 2025

Este artigo joga luz no imbricamento entre a colonialidade e o racismo, bem como, no entretecimento entre a decolonialidade e o antirracismo, com ênfase nas práticas de resistências negras, compreendidas como práxis insurgentes presentes tanto em marcos legais e jurídicos brasileiros, quanto desenvolvidas por professoras/es comprometidas/os com a transformação social por meio de uma educação intercultural crítica e na construção de uma sociedade fraterna, equânime e democrática. Para atingirmos esse escopo, trazemos as reflexões teóricas acerca dos conceitos de colonialidade, racismo, decolonialidade, interculturalidade crítica e práxis insurgentes, bem como, as discussões levantadas pelas teses das autoras, defendidas pelo Programa de Pós-graduação em Educação da Universidade Federal de Santa Catarina (PPGE-UFSC): “Entre silenciamentos e resistências: educação das relações étnico-raciais nas narrativas de professoras/es de Ciências Biológicas da UFSC” (PINHEIRO, 2020) e “Andarilhagens de professorxs: práticas de resistências negras na escola pública em Pelotas - RS” (PAULA, 2020).  No texto privilegiamos a escuta das narrativas, vozes (RIBEIRO, 2017), memórias e experiências (BENJAMIN, 2012) de professoras/es comprometidas/os com a luta antirracista e decolonial, bem como, teóricas/os terceiro-mundistas, em especial autoras/es negras/os e indígenas. Demarcando assim, posição teórico-metodológica e política ao escolher os referencias epistemológicos, as vozes que não se silenciam, que falam, que gritam junto conosco contra as injustiças da Colonialidade/Modernidade!
ESCOLA SEM PARTIDO E RAÇA: Uma Educação para a Colonialidade?
Authors: Garcia Caio Matheus de Freitas , Silva Caroline dos Santos Maciel , Teixeira Pedro Pinheiro
Published: January 2025

Ao longo da última década, observa-se o avanço do conservadorismo sobre diferentes esferas da sociedade brasileira. No campo educacional, esse avanço pode ser visto na atuação do movimento Escola sem Partido (ESP) em disputas sobre currículos, políticas e práticas escolares. Pesquisadores criticam as ações e posicionamentos do movimento, que reforçam concepções de educação autoritárias, discriminatórias e alinhadas à colonialidade. A colonialidade pode ser compreendida como um padrão de poder de vocação mundial, que tem como um  de seus fatores fundamentais a classificação da diversidade humana a partir da noção de raça, utilizada para naturalizar as dinâmicas de dominação colonial e que ainda permanece nas relações sociais. Em contrapartida, os estudos da decolonialidade e da interculturalidade buscam por novas formas de conhecer, pensar e ser que desafiem os significados e as lógicas da colonialidade. O objetivo deste artigo é identificar e analisar as características da colonialidade em pautas defendidas pelo movimento Escola sem Partido no que se refere às relações étnico-raciais. Para isso, realizamos um levantamento de textos disponíveis no blog do movimento na internet e analisamos seu conteúdo a partir de referenciais decoloniais, especialmente dos conceitos de colonialidade do ser, do saber e do poder. Os textos analisados expressam críticas recorrentes ao ensino de História e consideram como doutrinação abordagens que questionam a colonialidade. Dessa maneira, os discursos aglutinados no ESP reiteram a colonialidade sobre a educação, a sociedade e as relações étnico-raciais, representando um impedimento às práticas pedagógicas e currículos interculturais e decoloniais na educação.
O AINDA NÃO-COLONIZADO COMO REFERÊNCIA DIVERSA AO RELACIONAMENTO MODERNO COM A TERRA
Authors: Gonçalves Thiago Rodrigues
Published: January 2025

A tarefa a que se dedica a forma hegemônica de humanidade consiste em garantir as condições para a reprodutibilidade de seu modo de existência particular, cuja característica fundamental é a “cisão ontológica” que a aparta das demais coexistências em função da crença na excepcionalidade da racionalidade humana, que, por sua vez, autoriza uma atitude irresponsabilizável frente à produção de catástrofe que resulta do ímpeto colonizador da Terra esposado pelo ethos humano moderno, com fins a tornar a tudo em recursos (naturais e humanos) utilizáveis. Em contrário a esse avanço colonizador violento próprio da Modernidade permanecem modos e formas de existência que escapam ao desejo de controle experienciado como modo existencial e relacional pela humanidade moderna, compondo um conjunto amplo e complexo que denominamos como o que está, sob a perspectiva humana moderna, “ainda não-colonizado”. Ainda assim, tais modos e formas de existência divergentes ao projeto colonizador moderno compõem, mesmo com a forma hegemônica de humanidade, a relação dialógica que funda e exprime a “arena cosmopolítica”, cujo reconhecimento propomos como possibilidade diversa ao modo de relacionamento moderno que a humanidade vem mantendo com a Terra e demais coexistências, inclusive indagando sobre a possibilidade da consideração – atenciosa e cuidadosa – de “geograficidades diversas” à hegemonia humana humana moderna.

Foi produzido através de revisão bibliográfica que discorrem sobre a perspectiva do referido autor sobre a educação, assim como sua crítica ao ideal funcionalista anterior à sua perspectiva estrutural-construtivista. Tem como justificativa, a reflexão sobre o papel da escola na contemporaneidade, se como promotora de emancipação, se de reprodutora de desigualdades educacionais e, consequentemente, de desigualdades sociais.
A IMPORTÂNCIA DE TRABALHAR A IMAGEM DA POPULAÇÃO NEGRA DENTRO DO AMBIENTE ESCOLAR
Authors: Hokari Bastos Beatriz , Polizel Alexandre Luiz
Published: January 2025

No tangenciar entre a inferiorização da população negra dentro da sociedade e sua superação, as práticas dentro do ambiente escolar  são fundamentais na mediação de tal processo. Objetivamos aqui, por meio de uma pesquisa quantitativa exploratória de caráter bibliográfico e uma posterior análise de conteúdo, compreender, explicitar e discutir sobre as ações necessárias no contexto escolar e na formação docente, que visem trabalhar a valorização da história e herança cultural da população negra com os estudantes. O papel dos agentes educativos é imprescindível  dentro desse processo, juntamente à luta por uma sociedade livre de discriminações raciais e estereótipos. Mas ainda assim, é possível observar negligência por parte das instituições em não efetivar a aplicação de conteúdos referentes à História e Cultura Afro-Brasileira. Concluímos que, a falta de práticas dentro do contexto escolar, juntamente às dificuldades encontradas em sua adoção, se dão principalmente pela falta de preparação dos agentes educativos em trabalhar tal temática.
O NOVO ENSINO MÉDIO EM DISCURSO: da publicidade institucional a postagens no Twitter
Authors: Vieira da Silva Francisco , Magalhães Alberto Assis
Published: January 2025

O artigo analisa posicionamentos discursivos acerca do novo ensino médio, aprovado por meio da Lei n 13.415/2017, a partir do exame de enunciados presentes num vídeo de uma campanha publicitária do governo federal e em dez postagens do Twitter sobre o tema. Metodologicamente, trata-se de um estudo descritivo-interpretativo de natureza qualitativa. As análises permitiram constatar a emergência de posicionamentos discursivos discrepantes: enquanto no discurso oficial do governo, apela-se para um dizer de celebração acerca dos impactos positivos do Novo Ensino Médio para a educação brasileira, nas postagens do Twitter, esboçam críticas a esse modelo, de modo a incitar estratégias de resistência.

Authors: Brazil Vicente Thiago Freire , Barros Filho Edgar Marçal de , Santana José Rogério
Published: January 2025

A gamificação apresenta-se como uma eficaz metodologia adotada para a potencialização do processo de ensino-aprendizado em diversas áreas do conhecimento, especialmente por sua capacidade de engajar os aprendentes e torna-los, desde o início, protagonistas na jornada educativa. O ensino de cultura antiga, mais especificamente de Grego Clássico, também tem apropriado-se desse potencial inerente ao uso de jogos educacionais. O presente artigo tem como objetivo apresentar o percurso de uma Revisão Sistemática da Literatura que se dedicou ao levantamento de dados e informações oriundos de pesquisas que mesclam os campos do ensino de grego clássico e os processos educacionais de gamificação. Com isso, pretende apontar o atual estado da arte, assim como os dilemas contemporâneos e as propostas futuras para aonde apontam os projetos educacionais que se apropriaram desta estratégia metodológica. Os resultados obtidos demonstram que há uma enorme lacuna no registro acadêmico-científico de experiências educacionais que utilizem processos de gamificação para o ensino de grego clássico diante do universo de programas, sites, aplicativos que existem para essa finalidade, bem como os benefícios que o uso dessa estratégia pedagógica traz para o ensino de um idioma antigo.

Authors: Mishra Jyotsna , Mani Shukla Savinesh , Narvariya Parvati , Jain Shailesh
Published: January 2025

Maintaining good oral hygiene is crucial, with plaque buildup and increased oral microorganisms being major contributors to poor oral health. Various herbal extracts, including german chamomile, terminaliachebula, aloevera, green tea, peppermint satva, turmeric, neem, triphala, pomegranate extracts, guava extract, propolis, alum, darim leaves, mulethi, and others, exhibit properties similar to chlorhexidine in controlling plaque and reducing gingivitis. Many herbal mouthwashes contain herbs with antimicrobial, anti-inflammatory, and antioxidant properties. A combination of neem, tulsi, guava leaves, turmeric and ginger rhizome and clove oil extracts used as a mouthwash has shown to be more effective than chlorhexidine in gingival index, bleeding index and colony count. Therefore, using green herbal mouthwash can enhance oral hygiene without adverse effects. Thus maintaining optimal oral hygiene is crucial for overall health. Poor oral hygiene often results from plaque accumulation and an increase in oral microorganisms. In recent years, herbal mouthwashes have gained popularity for their potential benefits in promoting oral health. This research paper explores the advantage of herbal mouthwash when compared to the standard chlorhexidine mouthwash.

Background: Stem cells have been found to accelerate wound closure, promote tissue regeneration, and modulate the inflammatory response in diabetic wounds. Mesenchymal stem cells release growth factors and cytokines that stimulate angiogenesis, collagen synthesis, and the recruitment of immune cells, all essential processes in wound healing. Additionally, they possess immunomodulatory properties, reducing chronic inflammation often seen in diabetic wounds. Method: Published articles from indexed scientific journals on Stem Cell Therapy that were found to be relevant were chosen. The selected papers were analyzed for both quantitative and qualitative information on Stem Cell Therapy for Diabetic Patients. The compiled information was organized in a sequential manner for the understanding of the basics of Stem Cell Therapy in Diabetic Patients. Our research turned up articles considering the benefits and drawbacks of stem cell therapy. Result: Based on the findings of these articles, we would like to add that, although there are still many unanswered questions about long-term safety and standardized protocols, stem cell therapy has enormous potential. Stem cell therapy presents a glimmer of hope for those suffering from non-healing wounds, since it may be able to avoid amputation and enhance overall quality of life. Conclusion: It is possible to enhance wound healing through the application of various stem cell modifications, co-cultures, and scaffolds. Further research is required to ascertain the molecular workings of stem cells and to raise their therapeutic effectiveness inclinical practice.

Authors: El-Ghwas Dina E. , El-Waseif Amr A.
Published: January 2025

Bacterial cellulose (BC) has distinctive structural, physical, functional, and chemical characteristics. Recently, there has been growing interest in mass-producing BC for industrial uses to achieve greater cost-effectiveness and productivity in cellulose synthesis. This study aimed to enhance the productivity of BC by utilizing the Plackett-Burman Design to determine the optimal media composition and Taguchi's design for optimizing the culture parameters by Gluconacetobacter xylinus NRRL B-469. The impact of eleven cultural components on BC production was assessed using the Plackett-Burman Design. The results indicated that the variables with the greatest influence on BC production were Mannitol at a concentration of 25 g/L, H2SO4–heat-treated molasses at 110 ml, CSL at 80 ml, Citric acid at 1.15 g/L, and Na2HPO4 at 2.7 g/L. These optimal medium compositions resulted in a higher BC yield of 9.5 g/l. Furthermore, Taguchi's design accurately forecasted a yield almost double that of BC (18.04 g/l) under ideal production circumstances. The composition of the solution is as follows: Mannitol 25 g/L, H2SO4–heat-treated molasses 110 mL, CSL is 120 mL, citric acid 0.5 g/L, Na2HPO4 5 g/L. The total volume of the solution is 100 mL. The incubation period is 246 hours. The pH level is 5 and the temperature is maintained at 30oC. Additionally, the dried BC membrane was characterised using Scanning Electron Microscopy to establish its morphological structure and purity, X-ray Diffraction to assess its crystallinity, and FT-IR to analyse its chemical structure and functional groups. BC has fibrils that are somewhat thinner and have a more condensed structure, ranging from 73.9 to 161.0 nm. The utilization of experimental techniques, such as the Taguchi method and Plackett–Burman design, can serve as a valuable means to enhance the synthesis of bacterial cellulose pellicle. That could be serve as a promising material for specific applications.

Published: January 2025

Oxidative stress occurs when the body accumulates reactive oxygen species (ROS), which can be generated through enzymatic reactions or when oxygen interacts with cellular molecules. Antioxidants are frequently employed to impede, postpone, or minimize oxidative stress within the human body. These antioxidants supply electrons to free radicals, thereby counterbalancing their harmful effects. Compounds containing thiourea groups have attracted attention due to their diverse pharmaceutical properties, including their roles as antioxidants. This study aims to determine the antioxidant potential of the N-benzoyl-N’-naphthylthiourea (BNTU) and its four derivatives. This research evaluates the antioxidant activity of BNTU and its derivatives using the scavenging method of DPPH radicals. A docking study revealed potential interactions between binding models (human ROS1 kinase, PDB ID 3ZBF) and the antioxidant properties of the target compounds. Based on the results of the DPPH test, it was found that the antioxidant activity (IC50) for 4CFBNTU was recorded at 189.6 ppm, whereas 3CFBNTU showed a measurement of 294.5 ppm. Conversely, BNTU, 4TBBNTU, and 4OCBNTU displayed IC50 values surpassing 400 ppm. As for the Antioxidant Activity Index (AAI), The BNTU and its derivatives have AAI values < 0.56. The docking results obtained are consistent with the conclusions drawn from the antioxidant investigation. The four derivatives of BNTU have better antioxidant activity than the lead compound. Among them, 4CFBNTU exhibits the best antioxidant activity, although its antioxidant properties are relatively weak.

Published: January 2025

Background: Wound healing is a multifaceted process requiring the collaboration of various elements to facilitate the repair of damaged tissue. To accelerate healing process, Virgin Coconut Oil (VCO) and black cumin oil are plant oils that have been proven to offer several beneficial pharmacological effects. Therefore, this study aimed to determine the effect of VCO and black cumin oil, as well as their combination, on expression of TNF-α and histopathological features during wound healing process in diabetic rat. Methods: Rat were injected with streptozotocin (55 mg/kg BW) and a 10 mm wound was created (n=30). Subsequently, rat was randomly divided into six groups (n=5), consisting of control (Untreated), VCO, black cumin oil, C1, C2, and C3 groups. Topical oil application was performed once daily for 14 days. Wound healing between groups was evaluated using visual observation, with hematoxylin and eosin staining. Meanwhile, TNF-α gene expression was analyzed using RT-PCR on days 7 and 14, followed by data analysis with one-way ANOVA. Results: The C1 group receiving a topical application of a combination of VCO and black cumin oil showed a moderate wound closure pattern characterized by good shape, thickest epidermis, higher granulation, greater collagen density, and fibroblast, with lower inflammatory cell infiltration compared to others. The combination of VCO and black cumin oil in the C2 and C3 groups significantly decreased TNF-α gene expression on day 7. In contrast, on day 14, the C3 group significantly reduced TNF-α expression compared to the control group. Regarding histopathological features, the C1 group provided the optimal wound healing process compared to others.Conclusion: The combination of VCO and black cumin oil accelerated wound healing process by inducing a decrease in TNF-α expression and providing an intermediate healing pattern.

Nigeria today is rife with occurrences of intruders breaking into homes at every slight opportunity. The topic of security is quite important; hence this paper presents the development and implementation of a Smart Intruder Detection System utilizing the ESP32-CAM board, the Vibrometer and the ATMega328P microcontroller to enhance lighting, security, and surveillance functionalities. The ESP32-CAM serves as the central control unit, leveraging its built-in Wi-Fi and camera capabilities, while communicating with the ATMega328P microcontroller responsible for managing lighting, security, and surveillance components. The Vibrometer adds a vital layer of security by detecting vibrations associated with forced entry attempts. Upon sensing significant vibrations, the Vibrometer triggers the ESP32-CAM to start an immediate recording of potential intrusions. In the realm of lighting control, the ATMega328P regulates diverse light sources such as LEDs and smart bulbs. The ESP32-CAM facilitates a user-friendly experience, enabling seamless control and automation of the lighting system through a dedicated mobile application or voice commands. For surveillance purposes, the ESP32-CAM captures real-time video, streaming it to the user's mobile device or a centralized monitoring station. The ATMega328P contributes to the system's intelligence by supporting motion detection algorithms, which, in turn, trigger automated alerts and activate lighting or alarm systems in response to detected movement. The precision performance of the components was carried out and the average precision for all the components was 95%.  The synergistic integration of the ESP32-CAM board and ATMega328P microcontroller results in a cohesive and intelligent smart home automation solution.

Published: January 2025

Increased groundwater extraction for irrigation is leading to the intrusion of saline seawater into many wells in some communities in Anloga District, Volta Region, Ghana, with resultant adverse effects on crop productivity. This study investigated the water quality of selected wells in four communities of the district for their suitability for irrigation. Water samples were collected from 10 representative wells, purposively selected out of 60, to determine the pH, electrical conductivity, total dissolved salt by means of a pH/EC/TDS/Temperature portable meter, and the concentrations of sodium, potassium, calcium, magnesium, sulphates, chlorides, bicarbonate and nitrate, using standard chemical laboratory procedures. The geochemical characterization of the sampled water sources was carried out using the Piper trilinear diagram, and revealed the dominance of Na-Cl facies of the groundwater in Tegbi, Whuti and Anyanui, suggesting seawater encroachment connected with groundwater abstraction. The water samples from wells in Woe indicated the Ca-Mg-Cl-SO4 mixed type and are considered suitable for irrigation. About 50% of the sampled wells could be classified under the high salinity-low sodium hazard (C3-S1), 20% are under very high salinity-medium sodium hazard (C4-S2), another 20% under very high salinity-high sodium hazard (C4-S3) and 10% under medium salinity-low sodium (C2-S1) classes. These wells are prone to salinity, and farmers’ discretion is recommended through the adoption of conditional use of the irrigation water such as growing of salt-tolerant crops.

Left Ventricular Hypertrophy (LVH) is widely recognized as a predictor of adverse cardiovascular outcomes, including heart failure, arrhythmias, and sudden cardiac death. Objective: The basic aim of the study is to find the prevalence of left ventricular hypertrophy (LVH) in type-II diabetes mellitus at PAF Hospital Mushaf. Methods: This Cross-sectional study was conducted at the Department of Medicine, PAF Hospital Mushaf, Sargodha from January to July 2024. Data were collected through a non-probability, consecutive sampling technique. Data were collected using a self-generated questionnaire and included biodata like age, gender, contact number, and the presence or absence of LVH. Transthoracic 2D Echo was performed in selected individuals on the Toshiba Xario (Echo machine). Results: Data were collected from 154 patients with a mean age of 52.6 ± 7.4 years, with a nearly equal gender distribution, consisting of 48% male and 52% female participants. The average duration of diabetes was 10.3 ± 4.2 years, and the mean BMI was 28.4 ± 3.7 kg/m², indicating a mildly overweight population. Blood pressure was on average 140/90 ± 10/6 mmHg, with a significant proportion (61%) suffering from hypertension. Fasting blood glucose levels were elevated at 175.6 ± 34.8 mg/dL, and the mean HbA1c was 8.5 ± 1.2%, reflecting poor long-term blood sugar control. Conclusion: It is concluded that Left Ventricular Hypertrophy (LVH) is prevalent in a significant proportion of patients with Type 2 Diabetes, particularly those with longer diabetes duration and male gender. The findings highlight the importance of early detection and management of cardiovascular risk factors in diabetic patients and a significant gender difference, with male patients being more likely to develop LVH compared to females in this study were observed.

Published: January 2025

Mini-percutaneous nephrolithotomy (mini-PCNL) is a widely adopted technique for the treatment of renal stones, offering minimal invasiveness and high success rates. Efficient retrieval of stone fragments is critical for surgical success. This study compares the efficacy and safety of the whirlpool mechanism versus forceps retrieval during mini-PCNL in a tertiary care hospital in Pakistan. Objective: To evaluate the stone clearance rates, operative time, hospital stay, and complications associated with the whirlpool mechanism compared to forceps retrieval in mini-PCNL. Methods: This prospective randomized controlled trial included 90 patients undergoing mini-PCNL at the Institute of Kidney Diseases (IKD), Peshawar. Patients were randomly assigned into two groups: Group A (whirlpool mechanism) and Group B (forceps retrieval), with 45 patients each. Data on stone clearance rates, operative time, hospital stay, and complications were collected and analyzed using SPSS version 26, with a p-value ≤0.05 considered significant. Results: The stone clearance rate was significantly higher in Group A (91.1%) compared to Group B (77.8%, p=0.042). Operative time was slightly longer in Group A (90.6 ± 12.4 minutes) than in Group B (82.3 ± 10.7 minutes, p=0.032). Group A demonstrated a shorter hospital stay (2.8 ± 0.6 days) compared to Group B (3.4 ± 0.7 days, p=0.021). Complication rates, including bleeding, infection, and urinary leaks, were low and comparable between the groups. Conclusion: The whirlpool mechanism significantly enhances stone clearance rates and shortens hospital stays compared to forceps retrieval, with a comparable safety profile. These findings support the adoption of the whirlpool mechanism as a preferred method for stone fragment retrieval during mini-PCNL, particularly in resource-limited settings.

Suture implantation is a procedure to promote rearrangement of the extracellular matrix. Various cellular responses of post-suture implantation affect the outcome of this procedure. The current study aimed to analyze the effects of suture implantation using polycaprolactone/polylactic acid/hyaluronic acid (PCL/PLA/HA) on skin histopathology, expression of IL-6, and hematological parameters in rat models. To conduct the study, 25 male Sprague Dawley rats, three months old were randomly divided into five groups, including G1 (control), G2 (sham, group injected using skin cannula), and G3-G5 (suture implanted groups). For the suture-implanted groups, a cannula was used using suture materials. Specifically, G3 received truglyde implants, G4 received PCL/PLA/HA implants, and G5 received polydioxanone (PDO) implants. The back skin and blood samples were collected on day 3. Histopathological analysis was conducted on the samples using H and E, Congo red, immunohistochemistry against IL-6, and hematology. The analysis of the data revealed that the group with suture implantation using PCL/PLA/HA had the smallest wound area, compared to the other implanted groups. Further, the PCL/PLA/HA group showed a significant decrease in eosinophils infiltration and IL-6 level on the skin samples after suture implantation. Moreover, there were no significant differences across the groups in most of the hematological parameters after suture implantation, including total erythrocytes, hemoglobin, eosinophil, basophil, and monocyte levels. The total neutrophils increased after suture implantation in all groups, while the total lymphocytes decreased. It can be concluded that the best material according to parameters evaluated in the current study for suture implantation was PCL/PLA/HA.

The counter electrode plays a vital role in solarcell performance. Instead of using platinum (Pt) CE, many inorganic and organic counter electrodes (CEs) have been created for dye-sensitized solar cells (DSSCs). However, because of their exceptional chemical stability, low cost, simple fabrication, flexibility, transparence, potential for high efficiency and better electrochemical qualities, carbon nanocomposite and MoS2 have been crucial to CEs. In this work, we created a graphene nanocomposite with TMDs (MoS2, CoS2, and NiS2) integrated as a counter electrode that can be easily manufactured hydrothermally and utilized in DSSCs. Through the use of energy dispersive spectrum analysis, Raman, scanning electron microscopy, transmission electron microscopy, and X-ray diffraction, the structural, morphological, and elemental content of the samples were examined. In comparison to MoS2@graphene and CoS2@graphene, respectively, NiS2@graphene hybrid demonstrated superior electrical conductivity and catalytic activity as a substitute for platinum counter electrodes in dye-sensitized solar cells (DSSCs). When compared to MoS2@graphene (7.71 ± 0.03%) and CoS2@graphene (8.01 ± 0.05%), the resultant NiS2@graphene counter electrodes (CEs) showed greater power conversion efficiencies (8.42 ± 0.05%). The availability of catalytic edge sites, the three-dimensional (3D) structure of NiS2, which promotes electrolyte/reactant transport, and the exceptional electrical connection to the underneath graphene are responsible for the exceptional performance of DSSCs.  Therefore, our findings show that more research should be done 2D Graphene on the TMDs materials for dye-sensitized solar cells.
