Researchers from Osaka University probed the transit of cations across a nanopore membrane for the generation of osmotic energy. The team controlled the passage of cations across the membrane using a voltage applied to a gate electrode. This control allowed the cation-selective transport to be tuned from essentially zero to complete cation selectivity. The findings are expected to support the application of blue energy solutions for sustainable energy alternatives worldwide.

Researchers from The Institute of Scientific and Industrial Research (SANKEN) at Osaka University and collaborating partners prepared hierarchical hydrogels and moldings that consisted of anisotropic, ecofriendly cellulose nanofibers. By simply tailoring the applied voltage during fabrication, complex architectures—such as microneedles and multilayer hydrogels—were easy to prepare. The results of this work will reduce the need for petroleum-based plastics, and in so doing minimize a long-standing source of environmentally persistent waste.

Face masks have become an important tool in fighting against the COVID-19 pandemic. However, improper use or disposal of masks may lead to "secondary transmission". A research team from City University of Hong Kong (CityU) has successfully produced graphene masks with an anti-bacterial efficiency of 80%, which can be enhanced to almost 100% with exposure to sunlight for around 10 minutes. Initial tests also showed very promising results in the deactivation of two species of coronaviruses. The graphene masks are easily produced at low cost, and can help to resolve the problems of sourcing raw materials and disposing of non-biodegradable masks.
