This study addresses the fragmentation of research on technological innovations for the integration of renewable energy in smart cities, addressing the lack of systematic mapping of trends and knowledge gaps. To this end, a bibliometric analysis of scientific production (2018–2025) was conducted using a Boolean search strategy in databases, analysis in RStudio and VOSviewer to map keyword co-occurrences, collaborative networks, author and journal metrics, and an author–term–source Sankey diagram. The results revealed three clusters: one focused on "clean energy," "renewables," and "artificial intelligence"; another on "sustainable development," "energy policy," and "smart grids"; and an emerging cluster on "energy production." The collaboration map placed India as the main node, connected to China, Germany, and the US. Among the authors, Abed AM stood out with 167 citations, followed by Alsharif MH (26), Brent AC (9), Kumar P and Nedungadi P (8 each). The journals Energies and Energy Reports led the way with 34 and 32 publications. The Sankey diagram illustrated knowledge pathways between researchers, topics, and sources, highlighting specialization and collaborative opportunities. These findings offer a roadmap to guide policies and foster interdisciplinary collaboration for more sustainable cities.

This study presents the development and validation of an ecological roof tile made from organic compounds, conceived as a technical-environmental solution to construction and demolition waste (CDW) in highly vulnerable rural areas. Through an experimental approach, mixtures composed of sieved soil, horse manure, potato starch, vegetable shortening, and water were designed and evaluated across 15 successive trials using standardized molds. The final mixture demonstrated optimal conformability, morphological stability, structural cohesion, and preliminary mechanical resistance after natural drying. During its service phase, the inclusion of vegetable shortening creates a hydrophobic layer that limits moisture absorption, thus extending its functionality as a roofing component. In the event of structural fracture, this film disintegrates, allowing gradual water ingress and activating the material’s compostability as an organic soil conditioner. This dual functionality aligns with principles of circular design, enabling the material to transition from a constructive system to an agroecological input without requiring industrial recycling. The proposal was qualitatively validated through expert judgment and received international recognition in invention competitions, reinforcing its technical feasibility and replicability potential. Overall, the findings establish the ecological tile as a sustainable alternative for rural architecture, with a positive impact on both habitability and the circular management of materials in resource-limited settings.

This study aimed to determine the relationship between the use of financial tools and profitability in MSMEs in the La Perla market, located in Chimbote, Peru. The research was conducted using a quantitative approach, with a non-experimental cross-sectional design and correlational scope. Validated questionnaires were administered to all 54 formal MSMEs operating in this market, yielding results that demonstrate a highly significant relationship between the dimensions of financial analysis, financial planning, and use of the cash budget and profitability, achieving Spearman coefficients between 0.876 and 0.979. Among the most relevant findings, it is worth highlighting that the use of the cash budget showed the strongest relationship with profitability, allowing for the optimization of liquidity and the anticipation of contingencies, while financial planning strengthened resource control and financial analysis facilitated more accurate strategic decisions. Overall, the statistical analyses demonstrated that financial tools are crucial for improving the profitability of MSMEs, reinforcing their sustainability in a highly competitive environment. In conclusion, the systematic use of these tools significantly contributes to SMEs in the La Perla market strengthening their position in the local market and better facing the financial challenges of 2024.

The increase in energy consumption in urban buildings and the need for sustainability are driving renewable solutions with storage. This research proposes the design and evaluation of a lithium battery-based photovoltaic self-consumption system for a building in Peru, aiming to maximize energy autonomy, reduce grid dependence, and improve profitability. The study addresses the technical and economic challenges posed by solar variability and hourly demand in urban settings. The HOMER Pro software was used to simulate various configurations based on real solar irradiance data, load profiles, and updated costs. Optimization criteria included the Levelized Cost of Energy (LCOE), Renewable Fraction (RF), and Net Present Cost (NPC). The optimal configuration consists of a 400 kW photovoltaic system with 2168 lithium batteries, achieving a 100% renewable fraction, 54.9 hours of autonomy, and an LCOE of $0.649/kWh. The system generates an energy surplus of 42.7%, with potential applications in future technologies such as green hydrogen or electric mobility. However, the high cost of storage remains the main economic limitation of the project.

The collection of solid waste in bodies of water, such as rivers, represents a key challenge, given the environmental and social impact that this waste generates if not properly managed. The increase in water pollution and the need to protect aquatic ecosystems have motivated the development of various technologies to collect solid waste. Solutions reported in the literature include floating devices, passive barrier systems and automated mechanisms for efficient waste removal. Within this context, the design of a modular semi-automated system for the collection, separation and disposal of solid waste in the Tambo River is presented. This includes the installation of floating barriers for the initial waste capture, automatic systems through a conveyor belt, use of solar panels to provide energy and a module for waste collection, which contributes to the preservation of the ecosystem and is functional in a real environment.

The objective of the research was to analyze the relationship between the Fintech payment method and the income of micro and small enterprises (MSEs) in the district of Veintiseis de Octubre during the year 2022. A quantitative approach was used, with a non-experimental cross-sectional design and correlational scope. Data collection was carried out through surveys applied to a sample of 370 MSEs in the district. The results revealed a significant positive correlation between the two factors, with a Spearman coefficient of 0.754. This indicates that the use of financial technology for payments has a favorable influence on the income of MSEs, suggesting that the adoption of financial technologies can become a key strategy for improving the economic performance of these enterprises. The study also highlights that digitization and technological innovation not only optimize operational processes but also open up new business opportunities. By facilitating access to broader markets and improving the customer experience, financial technology is establishing itself as a transformative tool for the growth of microenterprises in today's environment.

From 2014 to 2024, Peruvian industrial companies under the supervision of the Superintendency of the Securities Market (SMV) faced financial challenges, including fluctuations in liquidity and operational efficiency. This study examined the impact of these factors on business profitability using return on assets (ROA) and return on equity (ROE) as key performance indicators. A quantitative approach with a non-experimental, correlational, and retrospective design was employed. The sample consisted of four industrial companies selected using non-probability convenience sampling. All of these companies reported weak financial results during the study period. The findings suggest that although there was a positive relationship between liquidity and profitability, it was not statistically significant (ρ = 0.256; p = 0.102). This indicates that liquidity alone does not determine economic performance. In contrast, operational efficiency showed a strong, statistically significant positive correlation with profitability (ρ = 0.960; p < 0.01), demonstrating that effective resource management directly contributes to profit generation. The joint analysis revealed significant heterogeneity among the companies, reflecting disparities in financial and operational practices. It can be concluded that, in addition to maintaining adequate Liquidity is also a critical factor in enhancing profitability. This is essential for ensuring financial sustainability in the industrial sector.
