Catalytic Performance Improvement in Polymer Derived Nanostructures for Fuel Cell Applications
Abstract: The performance and operational lifetime of PEMFCs are closely linked to the catalytic activity and durability of cathode electrocatalysts. In this research, a polymer-derived cobalt–iron nitrogen-doped carbon (CoFe–N/C) nanostructured catalyst is developed to enhance the ORR performance for PEMFC applications. PAN and melamine serve as nitrogen-rich polymer precursors, while cobalt and iron salts generate highly dispersed metal–nitrogen active sites within a porous carbon matrix through thermal treatment at 900 °C. …

Macro and Micronutrient Interactions with Malnutrition after Nutrition Education Intervention, Specifically with Regard to Nutritional Therapy and Diet Modification
Abstract: Nutrition and food have a crucial role in creating and sustaining optimum health. Physicians are interested in providing their patients with clinical nutrition therapy, but little is known about how they adhere to specific nutrition, in my opinion. Foods can contain a variety of various amounts and qualities of nourishing ingredients, which together make up nutrition. Patients in nutrition therapy learn how to make informed decisions once they select the …

A Comparative Techno-economic Analysis of Hydrogen Production Processes from Locally Available Resources in Nigeria
Abstract: In this work we report result of techno-economic analyses of three hydrogen production pathways - Steam Methane Reforming (SMR), SMR with Carbon Capture (SMR+CC) and Proton Exchange Membrane electrolysis (PEM) – using integrated process-cost simulation-estimation methodologies. Process modeling and simulation is performed with Aspen Hysys® and Aspen Plus® (V10). Cost modeling and estimation is based on full lifecycle cost of production using the Levelized Cost of Hydrogen (LCOH) approach. Feedstock …

Comparative Study on Thermal Performance of Mud Rammed and Concrete Residential Building Envelope in Paro - Bhutan
Abstract: A key factor in assessing the total energy efficiency of a building is the thermal performance of the building envelope. In Bhutan the building energy sector accounts for 15% of the total domestic electricity consumption out of which 50 to 60% accounts for space heating in the temperate region. Previous research findings and data also indicate that heat loss or gain through the building envelop were the most significant contributor …

Recent Advancements and Current Status of Hydrogen Fuel Cells: Materials, Systems, Applications, and Commercialization Prospects
Abstract: In the transportation, stationary electricity, and industrial sectors, hydrogen fuel cells have become a crucial clean-energy technology that can help achieve worldwide decarbonization. Significant progress has been made in catalyst design, membrane engineering, stack architecture, system optimization, and hydrogen generation pathways throughout the last ten years (2018–2025). Platinum group metal (PGM) loading has been significantly reduced, single-atom and transition-metal-nitrogen-carbon (M-N-C) catalysts for oxygen reduction have been developed (Wu et al., …

High-Performance Polymer Composite Membranes for Selective Ion Transport in Advanced Energy Conversion Systems
Abstract: The development of high-performance Polymer Composite Membranes (PCM) with enhanced ion transport is essential for Polymer Electrolyte Membrane Fuel Cells (PEMFC). However, low-humidity conditions and filter agglomeration still limit long-term membrane stability. This research designs a functionalized PCM integrating cross-linked Poly (Vinyl Alcohol)/Poly (Ethylene Glycol) (PVA/PEG) matrix with sulfonic acid functional groups and Titanium Dioxide (TiO₂) nanofillers to improve selective ion transport under low-humidity conditions. Two types of PCM were …

Intergenerational Cycle of Malnutrition & Ill Health
Abstract: Malnutrition is a pervasive global issue that significantly undermines the health, productivity, and overall development of individuals, particularly in low-income and developing regions. It affects all age groups but disproportionately impacts young children and women, perpetuating an intergenerational cycle of ill health and poverty. Factors such as economic disparities, lack of education, and entrenched social inequalities exacerbate the prevalence of malnutrition, making it a critical barrier to achieving sustainable development …
