      abstract     = {In situ energy generation in soft, flexible, autonomous
                      devices is challenging due to the need for highly
                      stretchable and fault-resistant components. Nanofluids with
                      pyro-, tribo-, or thermoelectric properties have recently
                      emerged as promising solutions for realizing liquid-based
                      energy harvesters. Yet, large thermal gradients are required
                      for the efficient performance of these systems. In this
                      work, we show that oil-based plasmonic nanofluids uniquely
                      combine high photothermal efficiency with strong heat
                      localization. In particular, we report that oleic acid-based
                      nanofluids containing TiN nanoclusters (0.3 wt $\%)$ exhibit
                      $89\%$ photothermal efficiency and can realize thermal
                      gradients as large as 15.5 K/cm under solar irradiation. We
                      experimentally and numerically investigate the photothermal
                      behavior of the nanofluid as a function of solid fraction
                      concentration and irradiation wavelength, clarifying the
                      interplay of thermal and optical properties and
                      demonstrating a dramatic improvement compared with
                      water-based nanofluids. Overall, these results open
                      unprecedented opportunities for the development of
                      liquid-based energy generation systems for soft, stand-alone
                      devices.},
