Hydrogen production from electrochemical water splitting via hydrogen evolution reaction (HER) powered by sustainable energy has been recognized as one of the most promising alternatives to traditional fossil fuels. To integrate the fundamental knowledge of chemistry, electrochemistry, and materials science with practical application and…

A survey and exploratory study were conducted to analyze Lake Tempe as a resource for contextual learning (CTL). The first phase of the study included exploring the lake's potential through interviews with the people who live in the lake's coastal region. Quadrat transects were done to identify aquatic plants around the lake. A feasibility…

Purpose: This paper aims to present insights on the governance of sustainability transitions in higher education in Africa. The authors interrogate the research literatures on the governance of socio-technical transitions in water, electricity, transport and waste management, and identify barriers and enabling factors that enhance transformative…

Purpose: The purpose of this study is to identify the most prevalent initiatives undertaken by leading universities in sustainability and offer a roadmap for other institutions seeking to undertake similar actions and contribute to more effective implementation of sustainability practices. Design/methodology/approach: By using a quantitative…

There has been little scholarship about the use of instructional practices in undergraduate environmental service-learning courses. In this study, we examined the implementation of high leverage practices (HLPs) in environmental service-learning courses (i.e. E-Corps). These HLPs included: eliciting initial ideas, informing approaches to problems,…

Stunting is an important issue as it leads to many adverse consequences on children's health. Pakistan is in public health crisis due to higher stunting rates in children. World Health Organization entails the prevalence of stunting to be less than 2.5% in a healthy population, but every third child is stunted in Punjab (largest province of…

The laser pointer has been widely used to demonstrate some simple optics phenomena, like reflection, refraction, total reflection, and diffraction. However, the rays of laser light cannot be seen in the air because the scattered light is too weak. Many physics teachers use milk or smoke to visualize rays of laser light in physics labs, but it is…

Water rockets can be used in a variety of ways, from schools to planetariums, with very young kids or adults. We propose here simple forms to work with water rockets, going one step further than a simple launch. A smartphone can be used to film the launch and analyze its motion with video analysis or it can even be attached to the rocket, using…

Safe and high-quality water is essential from both the health and environmental perspectives. Water quality is so important that the United Nations has included water in the 17 Sustainable Development Goals of the 2030 Agenda for Sustainable Development. Thus, the adequate control and treatment of water are necessities. These tasks must be…

This interview-based research study utilizes a phenomenological lens to explore student (n = 8) and faculty (n = 6) experiences associated with an international undergraduate research program named CHANCE. This program ran for three years (2021-2023) in Romania and focused on water issues confronting the Danube Delta according to the EU Water…

The Food-Energy-Water (FEW) Nexus envisions interactions between water, energy, and food systems, in which water allocation decisions constitute complex socio-hydrologic issues. Undergraduate students need to develop skills to understand and make effective decisions about the FEW Nexus. We implemented a comprehensive curriculum where undergraduate…

In the vicinity of a critical point, the impact of a substance's chemical identity is superseded by universal critical behavior for a number of physical properties, such as visible light scattering. In this classroom demonstration, students observe a single-phase critical mixture of partially miscible isobutyric acid + water (IAW) as the…

This study focuses on the experimental demonstration of the definition of kelvin using a triple point of water (TPW) cell and estimates the measurement uncertainty. The first part of this article is to construct the measurement setup and perform the measurements. The second stage is related with the calculation of uncertainty according to guides…

Although obscured in congressional debates over the Biden administration's broader domestic policy agenda, there is bipartisan consensus on the need to do more to ensure clean drinking water in schools and communities. Earlier this year, the U.S. Environmental Protection Agency (EPA) published revisions to rules on tightened restrictions on lead…

In recent years, chemistry educators are increasingly adopting immersive virtual reality (IVR) technology to help learners visualise molecular interactions. However, educational studies on IVR mostly investigated its usability and user perceptions leaving out its impact on improving conceptual understanding. If they evaluated students' knowledge…
