Abstract This study presents an integrated low-cost IoT-based evaluation framework assessment of photovoltaic (PV) modules enhanced using low-cost planar reflectors, supported by a custom IoT-based data logging system fo...

The development of dye-sensitized solar cells requires an in-depth understanding of the interfacial charge-transfer dynamics that take place between dye sensitizers and semiconductors. Here, we describe a prototype syste...

Context: Binary systems with similar components are ideal laboratories that allow several physical processes to be tested, such as the possible chemical pattern imprinted by the planet formation process. Aims. We explore...

Abstract This paper proposes an integrated and optimally tuned photovoltaic water pumping system (PVWPS) with high performance and operational stability under variable climatic conditions. The pumping process starts with...

Indonesia’s power sector is still dominated by fossil fuels, which makes it difficult for the country to meet its climate goals. This study develops an integrated modeling framework to evaluate long term decarbonizatio...

ABSTRACT In the Amazon region, agroforestry systems (AFSs) are recommended as a sustainable production alternative for local communities. A common component in Amazonian AFSs are tropical fruit trees, which can form the ...

Abstract Energy insecurity is a persistent yet insufficiently examined barrier to sustainable informal entrepreneurship in African cities. In Namibia, informal women entrepreneurs in low-income settlements face limited e...

En el artículo relatamos y analizamos experiencias en las que intentamos articular museos y educación. Presentamos propuestas en museos físicos y virtuales y recuperamos las voces de los participantes para analizar la...

Nowadays, performing multi-objective optimizations of actual building designs is one of the most challenging problems of the building energy efficiency area. This paper aims to propose an efficient method to solve multi-...

Background and Objectives: In recent decades, inadequate attention by designers to the thermal performance of commercial building façades has resulted in significant thermal inefficiencies in such complexes. This study ...

Power electronic devices are used to integrate clean energy systems (CES) like wind, solar, and other energy sources into the grid to meet the load demand. The parallel operated-inverters (POI) can improve the power capa...

Abstract Antibiotic residues in aquatic systems accelerate antimicrobial resistance and require efficient solar-driven advanced oxidation strategies. Herein, we engineer an oxygen-vacancy-rich La-doped NiFe₂O₄ spinel...

Abstract Low-Earth orbit (LEO) satellites encounter significant energy challenges during eclipse periods and low solar illumination, limiting mission autonomy, operational lifespan, and functionality. This paper presents...

Hybrid energy storage systems have shown promise in enhancing solar panel systems reliability and efficiency. However, managing the power distribution balance with multiple energy storage units remains a challenge. This ...

Nearly Zero Energy Buildings (NZEBs) are pivotal in addressing the escalating energy and environmental challenges of hot climates, where extreme cooling demands and reliance on fossil fuels intensify carbon footprints. T...

The proposal of the carbon peaking and carbon neutrality target has promoted the transition of power dispatching to low-carbon. In response to the problem that existing multi energy power dispatching methods are difficul...

Seasonal variations in diversity and biomass of tintinnids (Ciliophora: Tintinnida) were investi- gated at two fixed stations in the inner part of the Bahía Blanca Estuary (38°42` S, 61° 50` W) during an annual cycle....

The aim of this study was to evaluate sunscreens by Dispersive X-ray Fluorescence (EDXRF) and UV-VIS spectrophotometry, to quantify the sun protection factor (SPF) of the physical filter (micro-fine titanium dioxide) a...

Aims: In this paper, we analyze the collisional and dynamical evolution of the population of Plutinos. Methods: To do this, we test different collisional parameters and include a dynamical treatment that takes into acc...

The solar chemical composition is an important ingredient in our understanding of the formation, structure, and evolution of both the Sun and our Solar System. Furthermore, it is an essential reference standard against w...

Conventional wisdom indicates that a millisecond pulsar is recycled during the mass transfer stage in a binary system. Usually, the companion to the pulsar is a low-mass white dwarf. If zero ages are set at the end of ma...

Context: It is widely accepted that the large obliquity of Uranus is the result of a great tangential collision (GC) with an Earth size proto-planet at the end of the accretion process. The impulse imparted by the GC aff...
