“…By this method, we control T bulk over a wide range (∼300–1000 K). Alternatively, pressure-independent control techniques of T bulk via laser absorption , or laser cooling are readily available.…”

“…20,21,25−29 consequence, levitated NPs have found applications in force and inertial sensing 30−32 and have also been proposed to shed light on the transition between the classical and quantum worlds. 33,34 Recent advances in the field allow for contact-less manipulation of the bulk temperature 35,36 and the NP's charge with single elementary charge accuracy. 37 Here, we use the lately achieved level of control to study complex transformations of single NPs involving fast and simultaneous changes in mass (m), polarizability (α), charge (n q ), and surface composition.…”

“…Moreover, the increased Brownian motion of small NPs prevented their stable trapping with optical tweezers until recently. The young field of levitodynamics has enhanced the manipulation capabilities based on optical tweezers and now permits stable trapping of NPs in a fully controlled environment in high vacuum. ,,− As a consequence, levitated NPs have found applications in force and inertial sensing − and have also been proposed to shed light on the transition between the classical and quantum worlds. , Recent advances in the field allow for contact-less manipulation of the bulk temperature , and the NP’s charge with single elementary charge accuracy …”

A Chemical Nanoreactor Based on a Levitated Nanoparticle in Vacuum

et al. 2022

A single levitated nanoparticle is used as a nanoreactor for studying surface chemistry at the nanoscale. Optical levitation under controlled pressure, surrounding gas composition, and humidity provides extreme control over the nanoparticle, including dynamics, charge, and surface chemistry. Using a single nanoparticle avoids ensemble averages and allows studying how the presence of silanol groups at its surface affects the adsorption and desorption of water from the background gas with excellent spatial and temporal resolution. Herein, we demonstrate the potential of this versatile platform by studying the Zhuravlev model in silica particles. In contrast to standard methods, our system allowed the observation of an abrupt and irreversible change in scattering cross section, mass, and mechanical eigenfrequency during the dehydroxylation process, indicating changes in density, refractive index, and volume.

We investigate melting and undercooling in nanoscale (radius ∼100 nm) gold particles that are levitated in a quadrupole ion (Paul) trap in a high vacuum environment. The particle is heated via laser illumination and probed using two main methods. First, measurements of its mass are used to determine the evaporation rate during illumination and infer the temperature of the particle. Second, direct optical measurements show that the light scattered from the particle is significantly different in its liquid and solid phases. The particle is repeatedly heated across its melting transition, and the dependence of heating behavior on particle size is investigated. Undercooling�the persistence of a liquid state below the melting temperature�is induced via multistage laser pulses. The extent of undercooling is explored and compared to theoretical predictions.

Previous JQSRT special issues devoted to the "Laser-light and Interactions with Particles (LIP)" conferences were accompanied by prefaces written for issues published in a single volume, followed by peer-reviewer papers based on the topics discussed, but not necessarily presented, during the conferences, see [1] in [2], [3] in [4], and [5] in [6]. Papers associated to the LIP-conference in 2018 however, have been published as a virtual topical issue, the word "virtual" meaning that the papers have been published once they have been accepted, rather than collected in a single issue of JQSRT. In other words, the authors of accepted manuscripts have seen their papers o¢ cially published without having to wait for the rest of the manuscripts to get accepted. The corresponding preface/afterword was published in 2019 [7]. The 2020 conference was scheduled to be held in Warsaw, Poland, but has been postponed to 2022 due to the Covid pandemic. It has been decided, nevertheless, to publish another virtual issue of JQSRT to limit the e¤ects of the impact of the pandemic and stick to a tradition as much as possible.LIP conferences were in the …liation of a series of conferences which started under the name of "Optical Particle Sizing, OPS, theory and practice" in Rouen,
