“…Several studies back this up:  [21] mentioned that in well-designed interior zones, daylight improves visual quality and mental health benefits that are expensive and difficult to replicate with artificial lighting, it also added that Sunlight appears to be the best lighting source for schools because it provides an adequate quantity and spectrum of light as well as the proper timing and duration of light exposure.  According to [22], people who work in natural sunlight are more productive, effective, and happy than those who work in traditional artificial light.…”

The importance of research: human beings are greatly affected by their surroundings, especially in learning spaces. Lighting, colors, seating arrangement, and other factors all have a physical and psychological impact on students, which is reflected in their behavior, and performance.Research problem: Although there have been previous studies that have linked a student's behavior to the interior design elements of the learning space, there is no extensive, combined study that can guide the design of university educational spaces to achieve the highest possible efficiency for the students.Research Objective: Set criteria to assess the learning space; this standard states whether or not a learning space can provide an appropriate learning environment that can help students physically and psychologically.Research methodology: (theoretical approach) relied on a review of previous theoretical and practical studies to gather sufficient information to determine the criteria for evaluating each element of the educational space and how it impacts students, this is shown by presenting definitions of human behavior and how it is influenced by the built environment, and then used to illustrate how the interior architectural design of the educational space impact students, reaching the ideal status for each element in the final table. (analytical approach) in which a questionnaire was conducted for students as a field study and then analyzed for results.Results showed that many existing educational spaces have problems with interior design elements. Some of these problems, such as lighting, ventilation, and temperature, can be avoided from the beginning by orienting educational spaces correctly and thus obtaining adequate natural lighting, ventilation, and temperature without having to rely on industrial means. Noise can also be reduced if a suitable location away from the noise is chosen, as well as careful selection of finishing materials of sound insulation material. Table 8 shows additional means of isolation that can be used in existing spaces. On the other hand, the color of the white wall, which many studies have confirmed harms the space users of students and teachers but is still used, is a problem that is easily avoidable but still recurring. It is preferable to use cold or warm colors instead, as shown in Table 8. The significance of this research is in assisting in the creation of a suitable educational space that meets the needs of students while avoiding all of the problems mentioned above in many educational settings.

“…Electrical energy consumption is one of the factors that most impact the environment and the economy because this resource is fundamental for the functioning and development of the human being [1][2][3][4][5]. According to the European Commission, approximately 2900 TWh of artificial energy are consumed annually, leading to the emission of 1.7 million tons of CO2 [6][7][8]. This alarming scenario has led to an increased interest in developing low-cost, highperformance, and energy-efficient technologies, materials, and devices.…”

Advances in hybridised and inorganic composite metal halide perovskites: A review

Opto-Electronics Review

View full text Add to dashboard Cite

In recent years, metal halide perovskites have gained significant attention due to their unique optical and electronic properties of semiconductor materials, which make them ideal for use in sustainable and energy-efficient devices. These devices include solar cells, lasers, and light-emitting diodes. Therefore, this review aims initially to provide an overview of the most important characteristics of metal halide perovskites, including their engineering development in various types, such as those based on lead or lead-free materials, like tin or germanium. Additionally, perovskites made from purely inorganic compounds like caesium bromide, chloride, or iodide, as well as hybrids mixed with organic compounds like formamidinium and methylammonium halides will be discussed. The goal is to improve their stability and efficiency. Secondly, some of the studies have proposed technologies combining electronic and mechanical characteristics of flexibility or rigidity as required, promoting their synthesis with different materials such as polymers (poly methyl methacrylate, polyvinylidene fluoride), biopolymers (starch, cyclodextrin, polylactic acid, and polylysines), among others. Finally, the subject of this work is to establish the main purpose of the research carried out so far, which is to develop simpler and more scalable processes at industrial level to achieve greater efficiency and duration in storage, exposure to visible light, critical environments, humid or high temperatures.

“…Human health and wellness are key topics in fields that look at modern social and economic aspects, along with the improvement of the quality of individual life [1,2]. These trends of focusing on human health, wellness, and individual quality of life have also been emphasized as important in the areas of architecture and interior design [3,4]. On average, people spend 90% of their working hours in indoor spaces.…”

Recently, human well-being has emerged as a pivotal concern that affects not only quality of life but also social and economic dimensions. Lighting in office spaces is crucial for the health and cognitive function of occupants, and various methods are used to assess it. However, there is still a lack of research investigating the relationship between lighting satisfaction and its key factors in diverse spaces. This study focused on the office light environment, using quantitative and qualitative data analysis to understand occupants’ satisfaction and the factors influenced by lighting characteristics. According to the results, occupant satisfaction was higher in light environments with illuminance levels exceeding the appropriate illuminance standard. Furthermore, the influx of daylight and its influencing factors, such as daylight exposure and window size, played a significant role in enhancing satisfaction. However, while daylight was a primary source of glare, its mitigation was not solely reliant on installations, such as blinds; architectural designs, including space arrangement, were also crucial in addressing it. Furthermore, the perception of the lighting environment varied based on work behaviors and spatial arrangements, influencing satisfaction with the lighting conditions. Therefore, a comprehensive approach that considers lighting elements, human behavior, and architectural design is essential in creating a lighting environment for office occupants.
