Elucidating strategies to design tailored chitosan surfaces with enhanced antibiofouling and biocompatibility properties via plasma assisted processes
Bacteria colonization of surfaces is often an undesired process. It affects human activities across different fields, including agriculture, marine transportation, the food, textile, oil and biomedical industries. Its negative effects incur in economic and human lives losses. Bacteria colonization …

Growth and applicability of radiation-responsive silica nanowires
Surface energetics play an important role in processes on the nanoscale. Nanowire growth via vapor-liquid-solid (VLS) mechanism is no exception in this regard. Interfacial and line energies are found to impose some fundamental limits during three-phase nanowire growth and lead to formation of …
