Summary: Harnessing exotic optical forces can lead to various biophysical applications and novel light-matter interactions. This study presents a coordinated scheme to simultaneously utilize pulling force and lateral force, achieving a dynamically controlled 2D microvehicle. By leveraging the helicity-dependent features of these forces and adjusting the ellipticity of incident light, the ratio of both forces can be dynamically and arbitrarily controlled.

Summary: We study quantum trapping effects in planar nanocomposite materials and find that they strongly depend on the characteristics of spatial inhomogeneity. The presence of inclusions leads to intense repulsive Casimir-Lifshitz force due to strong optical scattering and absorption size-dependent resonances. Comprehensive knowledge and a detailed description of the potential inhomogeneity in materials are necessary for analyzing quantum trapping effects.

Summary: The absence of a versatile, scalable, and defect-free bottom-up assembly of nanoparticles has been a challenge for the large-scale integration of nanoparticle-based devices. In this study, we propose a self-limiting dielectrophoretic approach that can precisely align nanoparticles onto electrodes over a large area. Experimental results show a 70% yield of single-nanowire assembly, and factors limiting the current yield are discussed. Improving nanoparticle-electrode contact and reducing capillary force during the drying process are expected to further increase the yield. The approach also demonstrates versatility for scalable and site-selective alignment of various nanoparticles.

Summary: In this study, we show that optical pulling forces (OPFs) can be generated by a hybrid dimer composed of a Si nanoparticle and a coated nanoparticle with a gain core and Au shell under normal plane wave illumination. The interaction between the electric dipole (ED) modes excited in the nanoparticles is identified as the underlying mechanism. The OPFs exerted on the nanoparticles depend on the gain level of the core materials, incident polarization angle, and nanoparticle sizes, and can also be observed in a trimer system.

Summary: In this study, an acoustic full-space digital metasurface consisting of arrays of dual-channel elements with variable coding states is proposed and experimentally demonstrated. The reflected and transmitted sound waves can be independently and dynamically controlled. The presented element achieves high efficiency (up to 80% in transmission mode and nearly 100% in reflection mode) and enables decoupled modulations of the reflection and transmission coefficients. Tunable beam deflection and alterable wave focusing are experimentally validated without inter-modal crosstalk on both sides of the platform.

Summary: In this study, a scalable selective absorber with a quasiperiodic nanostructure composed of densely arranged Fe3O4 nanoparticles was reported for high-performance energy conversion of low-grade solar energy. By investigating the scale effect of the quasiperiodic densely arranged plasmonic nanostructure, a significant solar absorption rate of over 94% and ideal passive suppression of thermal emissivity below 0.2 were achieved simultaneously. A flexible planar solar thermoelectric harvester was demonstrated, reaching a significant sustaining open-circuit voltage of over 20 mV/cm(2) under natural sunlight (AM1.5G), without a heat sink. This highly versatile strategy is expected to lead the exploration of energy evolution in fundamental research and pioneer next-generation, high-performance, economical, and practical solar co-harvesting systems.
