3D temperature mapping critical to understanding the nanoworld (ThermoRise)
CoordenadorEuropean Comission
Nanometre-scale devices capable of measuring temperature variations at a molecular level are valuable in both fundamental and applied science. For example, they can quickly measure micromachine overheating or the temperature inside of a cell. Although they hold tremendous promise for many applications, their 2D resolution has been a lim...Desenvolvimento de termometria sem fios a 4D tendo como alvo a ablação de tumores (PTDC/NAN-MAT/3901/2020)
