Light-to-heat conversion of optically trapped hot Brownian particles
Elisa Ortiz-Rivero, Sergio Orozco-Barrera, Hirak Chatterjee +6
Anisotropic hybrid nanostructures stand out as promising therapeutic agents in photothermal conversion-based treatments. Accordingly, understanding local heat generation mediated b…
Hot Brownian Motion of thermoresponsive microgels in optical tweezers shows discontinuous volume phase transition and bistability
Miguel Angel Fernandez-Rodriguez, Sergio Orozco-Barrera, Wei Sun +4
Microgels are soft microparticles that often exhibit thermoresponsiveness and feature a transformation at a critical temperature, referred to as the volume phase transition tempera…
Heating and Cooling are Fundamentally Asymmetric and Evolve Along Distinct Pathways
Miguel Ibáñez, Cai Dieball, Antonio Lasanta +2
According to conventional wisdom, a system placed in an environment with a different temperature tends to relax to the temperature of the latter, mediated by the flows of heat and/…
Electro-Thermo-Plasmonic Flow in Gold Nanoparticle Suspensions: Nonlinear Flow Velocity Dependence with Aggregates Concentration
Carlos David González Gómez, Raúl A. Rica, Emilio Ruiz-Reina
Efficient mixing and pumping of liquids at the microscale is a technology that is still to be optimized. The combination of an AC electric field with a small temperature gradient l…
A chemical nano-reactor based on a levitated nanoparticle in vacuum
Francesco Ricci, Marc T. Cuairan, Andreas W. Schell +4
A single levitated nanoparticle is used as a nano-reactor for studying surface chemistry at the nanoscale. Optical levitation under controlled pressure, surrounding gas composition…
Kovacs memory effect with an optically levitated nanoparticle
Andrei Militaru, Antonio Lasanta, Martin Frimmer +3
The understanding of the dynamics of nonequilibrium cooling and heating processes at the nanoscale is still an open problem. These processes can follow surprising relaxation paths…
Extending vacuum trapping to absorbing objects with hybrid Paul-optical traps
