Article development standard
Each topic will be developed as a standalone technical article with scientific principles, reaction equations where relevant, precursor selection, worked calculations, experimental workflow, critical parameters, characterization strategy, common failure modes and primary references. Reported experimental conditions will be tied to the cited material composition and source rather than presented as universal recipes.
Figures and references
Original explanatory diagrams and flowcharts will be stored in this topic’s images/ directory. References will prioritize peer-reviewed primary literature, authoritative reviews and relevant equipment or chemical-manufacturer documentation. Reused third-party figures will require appropriate permission or licensing and attribution.
