Performance Investigation of Eco‐Friendly Refrigerant Mixtures as an Alternative to R134a in Vapour‐Compression Refrigeration System

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The growing impacts of climate change and energy scarcity demand environmentally sustainable refrigeration solutions. This study investigates eco‐friendly refrigerants (R152a, R290 and R600a) and their optimized ternary mixture as alternatives to R134a. Four blend compositions were analysed using experimental testing and REFPROP 10.0 modelling

Methane Pyrolysis Performance in Catalytic Molten Media for Hydrogen Production From the Perspective of Bubble Column Reactor Design and Configuration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the hydrogen production routes from natural gas (methane), methane pyrolysis offers a cleaner option than the established steam methane reforming by producing CO2‐free hydrogen. However, in fixed bed reactors over solid catalysts, this technology experiences rapid catalyst deactivation due to carbon (coke) deposition encapsulating its ...

Novel application of gamification to support undergraduate anatomy: Student perceptions and performance

Anatomical Sciences Education, EarlyView.
Abstract Anatomy is a foundational component of various medical and paramedical disciplines. Existing research has suggested that games or game elements can improve student interest in musculoskeletal (MSK) anatomy. This project builds on previous gamification and serious game work and incorporates new anatomy‐based games into undergraduate anatomy ...

Confirmation of a Non‐Transiting Planet in the Habitable Zone of the Nearby M Dwarf L 98‐59

Astronomische Nachrichten, EarlyView.
ABSTRACT Only 40 exoplanetary systems with five or more planets are currently known. These systems are crucial for our understanding of planet formation and planet‐planet interaction. The M dwarf L 98‐59 has previously been found to show evidence of five planets, three of which are transiting.

Modeling atmospheric escape from exoplanets

Atmospheric escape, where exoplanets lose their atmospheres to space, plays a critical role in planetary evolution, potentially stripping gaseous planets of a large portion of their envelopes, or eroding rocky planets' atmospheres, affecting their habitability.

Emotional nourishment begets academic coping during the primary to secondary school transition

British Educational Research Journal, EarlyView.
Abstract The transition from primary to secondary school is widely viewed as the most demanding in a child's educational journey. Despite a wealth of research on this transition, little is known about the children's ‘lived experience’ of it across different contexts.
