An in-depth investigation of the optical properties and device performance of Mn4 þ -activated phosphors will promote the application of this cheap and abundant resource in the field of solid-state lighting, thus reduce the consumption of expensive rare-earth such as Eu. In this work, we ...
Hence, it is highly in demand to apply cheap but efficient battery thermal management (BTM) strategies to control the temperature of batteries within the safe range. Among all the strategies to facilitate heat dissipation, natural cooling and forced air cooling [[16], [17], [18]], direct ...
