Supercapatteries as Hybrid Electrochemical Energy Storage Devices: Current Status and Future Prospects.

Among electrochemical energy storage (EES) technologies, rechargeable batteries (RBs) and supercapacitors (SCs) are the two most desired candidates for powering a range of electrical and electronic devices. The RB operates on Faradaic processes, whereas the underlying mechanisms of SCs vary, as non-Faradaic in electrical double-layer capacitors (EDLCs), Faradaic at the surface of the electrodes in pseudo-capacitors (PCs), and a combination of both non-Faradaic and Faradaic in hybrid supercapacitors (HSCs). EDLCs offer high power density but low energy density.

To that end, graphene oxide (GO) and reduced GO (RGO) have been extensively employed for preparing supercapacitors.

The ecological impact of plastic pollution in a changing climate.

Assessing three interlinked issues, plastic pollution, climate change and biodiversity loss separately can overlook potential interactions that may lead to positive or negative impacts on global ecosystem processes. Recent studies suggest that threatened species and ecosystems are vulnerable to both plastic pollution and climate change stressors. Here we consider the connectivity and state of knowledge between these three environmental issues with a focus on the Global South.

Trophic transfer of microplastics in the aquatic ecosystem of Sundarbans mangrove forest, Bangladesh.
