All efforts to obtain, reuse or purify water are extremely significant for society. Recently, researchers have begun delve in an idea born decades ago: the desalination of using highly porous electrodes. It is based on a fundamental aspect electrical double layers, namely, their huge capacitance. The ions solution can be partially removed under application electric field when fills space between electrodes, either bare (CDI, capacitive deionization), coated with ionic exchange membranes...

Conventional chemotherapy against colorectal cancer (CRC), the third most common in world, includes oxaliplatin (Oxa) which induces serious unwanted side effects that limit efficiency of treatment. Therefore, alternative therapeutic approaches are urgently required. In this work, biomimetic magnetic nanoparticles (BMNPs) mediated by MamC were coupled to Oxa evaluate potential Oxa-BMNP nanoassembly for directed local delivery drug as a proof concept future development targeted CRC....

In recent years, the capacitance of interface between charged electrodes and ionic solutions (the electric double layer) has been investigated as a source clean energy.
