Summary: This study investigates the use of nanophotonic structures to accurately determine the position of nearby nanoscale objects with subwavelength accuracy. By perturbing the near-field environment of a metasurface transducer consisting of nano-apertures in a metallic film, the location of the nanoscale object is transduced into the transducer's far-field optical response. The research demonstrates two-dimensional localization of objects accurate to 24 nm across a 2 x 2 µm area by monitoring the scattering pattern of the nanophotonic near-field transducer and comparing it to reference data. Additionally, increasing complexity in the nanophotonic transducer allows for localization over a larger area while maintaining resolution by encoding more information on the object's position in the transducer's far-field response.

Summary: By optimizing the printing and processing strategies of piezoceramics, highly responsive piezoelectric microtransducers can be produced. These 3D printed dense piezoelectric elements have high piezoelectric coefficients and complex structures, with a piezoelectric charge constant of 583 pC/N and a coupling factor of 0.57, approaching the properties of pristine ceramics. The integration of transducer packaging materials and 3D printed piezoceramics enables miniaturized ultrasonic devices capable of acoustic focusing and localized cavitation within millimeter-sized channels.

Summary: Chemotherapy-induced peripheral neuropathy (CIPN) is common in cancer patients but poorly managed due to the lack of reliable diagnostic techniques. In this study, a near-infrared chemiluminophore (MPBD) was synthesized and developed into a water-soluble activatable probe (CalCL) for in vivo imaging of CIPN. The probe allows for sensitive detection of paclitaxel-mediated CIPN in living mice, which is not achievable with fluorescence imaging. This research not only develops a highly efficient chemiluminescent probe, but also presents the first optical imaging approach for high-throughput screening of neurotoxic drugs.

Summary: This study demonstrates near-field second harmonic generation (SHG) imaging of 2D semiconductors and heterostructures using a scattering-type nano-optical apparatus, achieving a spatial resolution down to 20 nm. Excitons in atomically thin transition metal dichalcogenides greatly enhance the near-field SHG efficiency. By correlating nonlinear and linear scattering-type nano-imaging, nanoscale variations of interlayer stacking order in bilayer WSe2 are resolved, revealing stacking-tuned excitonic light-matter interactions.

Summary: The nonlinear optical response of a four-level double-V-type quantum system interacting with a two-dimensional array of metal-coated dielectric nanospheres was investigated. It was found that the Kerr nonlinearity of the system can be controlled and enhanced by varying the distance of the quantum system from the plasmonic nanostructure, and adjusting the relative phase of the applied fields can change the polarization rate of one of the laser fields.

Summary: Ammonium synthesis from nitrate has been demonstrated using a combination of electricity and light. Gold nanoparticle electrocatalyst with dual attributes of nitrate reduction activity and visible-light-harvesting ability was used to achieve a 15x boost in activity compared to conventional electrocatalysis. Non-thermal effects induced by plasmonic excitation, such as energetic carriers and charged interfaces, were found to play a crucial role in the observed enhancement.

Summary: In this study, 3-mercaptopropionic acid (3-MPA)-capped core/shell/shell ZnSeS/Cu:ZnS/ZnS QDs were synthesized in aqueous phase. The influence of Cu dopant location and loading on the photoluminescence properties of the QDs was investigated. The results showed that introducing Cu dopant in the first ZnS shell led to QDs with the highest PL quantum yield. Additionally, the emission color shifted from blue-green to green with increased Cu doping.

Summary: The development of advanced plasmonic applications is focused on achieving active devices. Active plasmonic nanostructures with tunable resonances have the potential to be used in optoelectronics for sensing and logic operations. In this study, we used simulations to compare the optical properties of nanocones and nanocylinders embedded in a photochromic medium. We found that the photochromic transition leads to strong coupling behavior, enabling a nanocone to enhance emission at one wavelength while suppressing emission at another wavelength.

Summary: This article reports a subwavelength imaging approach based on the interaction between the enhanced optical near-field around chiral nanoparticles and an azobenzene molecular probe. It is experimentally demonstrated that the near-field of chiral structures exhibit dissymmetry under left and right circular polarizations. The near-field dissymmetry factor, related to the local circular dichroism of the near-field intensity, can be experimentally mapped.

Summary: Plasmon-assisted electrochemistry provides a new approach to use light energy for chemical and fuel manufacturing. Plasmonic excitation enhances and modulates electrochemical processes, and nonthermal carriers generated by plasmonic excitation promote improved reaction kinetics and new modes of electrocatalytic activity. These effects can be utilized to make electroconversions more efficient, selective, and reduce the reliance on precious metals. However, there are still fundamental and practical issues that need to be addressed.

Summary: Using a transmission electron microscope with laser excitation, we observed Ostwald ripening of Au-Cu alloy nanoparticles under plasmonic excitation. This structural transformation, distinct from electron-beam-induced coalescence, is not thermally induced but instead triggered by plasmonically excited carriers.

Summary: Researchers used a high-resolution transmission electron microscope to observe the structural evolution of Cu-based nanoparticles under electron beam irradiation and plasmonic excitation. They found that these particles undergo hollowing via the nanoscale Kirkendall effect. Hollowing is triggered by electron beam irradiation, and plasmonic excitation enhances the kinetics of the transformation, likely through the effect of photothermal heating.
