Salt intake is too high for safety nowadays. The main active ion in salt is sodium. The vast majority of scientific evidence points out the importance of sodium restriction for decreasing cardiovascular risk. International Guidelines recommend a large re
During the test of a full battery composed of a copper, iron and manganese metal oxide cathode, a high reversible specific capacity of 290 mAh g−1, an average operating voltage of 3.2 V, and an energy density of about 207 Wh kg−1 were obtained. For one-dimensional materials, ...
Ti surfaces always have a thin, formed, natural oxide layer (TiO2) due to their easy reaction with oxygen in the atmosphere [44]. Hence, the formation of TiO2 can be achieved via simple, cost-effective, and eco-friendly procedures [45,46,47]. Upon calcination, TiO2 with varying surface ...
