Volume 3, Issue 1

This issue presents six contributions that span three closely connected fronts of sustainable-materials research. A first group addresses water-pollution control, examining how advanced photocatalysts and adsorbents can be engineered to remove organic dyes and pharmaceutical residues from aqueous systems. A second group focuses on nanofiber and membrane fabrication science, where electrospinning and related techniques are used to translate active materials into self-standing, retrievable architectures suitable for repeated deployment. A third contribution extends the issue's scope toward energy conversion, using device-level simulation to map optimization pathways for next-generation thin-film photovoltaics. Read together, these papers reflect a shared methodological outlook: the deliberate pairing of materials design with operational practicality — recoverability, scalability, and device-level performance — that increasingly defines sustainable-materials engineering. They also illustrate the field's growing tendency to treat fabrication strategy, material composition, and end-use performance as a single integrated design problem rather than as separate optimization steps.
