Abstract Spin–orbit coupling (SOC) in tightly focused optical fields offers a powerful mechanism for manipulating the complex motion of particles. However, to date, such has only been applied single-orbit particles, while multi-orbital dynamics have not yet experimentally demonstrated. Here, theoretical and experimental realization dual-orbit rotational nanoparticles circularly polarized Laguerre-Gaussian beam is reported. Analyses reveal that rotation originates from SOC vortex beam, with...
We proposed an innovative method to achieve dynamic control of particle separation by employing viscoelastic fluids in deterministic lateral displacement (DLD) arrays. The effects shear-thinning and elasticity working on the critical size DLD arrays are investigated. It is observed that each effect can lead variation approximately 40%. Since strength fluid related shear rate, for first time be easily realized through tuning flow rate microchannels.
This paper proposes and implements a lightweight, “real-time” localization system (SORLA) with artificial landmarks (reflectors), which only uses LiDAR data for the laser odometer compensation in case of high-speed or sharp-turning. Theoretically, due to feature-matching mechanism LiDAR, locations multiple reflectors reflector layout are not limited by geometrical relation. A series algorithms is implemented find track features environment, such as method, motion technique, matching...
Singlet fission (SF) presents an attractive solution to overcome the Shockley–Queisser limit of single-junction solar cells. The conversion from initial singlet state final triplet is mediated by correlated pair 1(T1T1). Despite significant advancement on 1(T1T1) properties and its role in SF, a comprehensive understanding energetic landscape during SF still unclear. Here, we study unconventional system with excited-state aromaticity, i.e., cyano-substituted dipyrrolonaphtheridinedione...
