 Supporting a  generic Nitrogen-to-Protein Conversion Factor (NCF) of 5.0  for algae species is gaining attention as a practical solution in international standards where species-specific values are not yet scientifically confirmed. Since algae contain significant amounts of  non-protein nitrogen compounds , using the traditional conversion factor (6.25) may overestimate protein content. Adopting an NCF of  5.0  helps improve accuracy, consistency, and transparency in reporting algal protein values across research, food innovation, and biotechnology sectors 🌱🔬📊. In the rapidly expanding algae-based food and nutraceutical industry , reliable protein estimation is essential for labeling, trade compliance, and regulatory acceptance. A standardized interim factor like NCF 5.0 supports harmonization between laboratories and international stakeholders while minimizing misleading nutritional claims. This approach also encourages fair comparison among microalga...

Flame spray pyrolysis (FSP) has emerged as a powerful and scalable technique for designing advanced nanocatalysts, and its application in synthesizing Pd–Pt/Al₂O₃ isolated dual-atom catalysts is truly groundbreaking 🚀. In this process, palladium (Pd) and platinum (Pt) atoms are finely dispersed on an alumina (Al₂O₃) support, forming isolated dual-atom active sites.
