However, achieving high-speed and directional rotation of microparticles using a static low-power-density light source remains a challenge. We propose asymmetric Marangoni flow to drive the rapid rotation of microparticles, and demonstrate that a dimeric active microparticle (DAP) exhibits high-speed directional rotation in a low-power-density annular optical trap at the water–air interface. The driving force arises from the asymmetric Marangoni flow induced by the non-uniform laser heating of the DAP. The average linear velocity of the DAP rotation is regulated by the laser power. Furthermore, the enhanced asymmetry results in larger rotation speed, which is experimentally corroborated by polystyrene sphere with larger diameter. The rotation speed of the particle depends on the competition between the increase in the viscous drag force in Marangoni flow and the increase in the viscous drag force in still water. Finally, the asymmetric Marangoni flow is successfully utilized to drive the rotation of trimeric active microparticles and cell-carrying DAPs. This technology, characterized by its low power density and small temperature rise, demonstrates promising potential for applications in active matter, microscale robotics, and drug/cell delivery microsystems.</div></div>","PeriodicalId":19511,"journal":{"name":"Optics and Laser Technology","volume":"192 ","pages":"Article 113618"},"PeriodicalIF":4.6,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144679573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pore defects always originate from trapped bubbles. However, most studies focused on post-analysis for pore defects after solidification. There are limited investigations on the influence of process parameters on bubble formation and retention during deposition using real-time observation. In this paper, the influence of laser power and scanning speed on both bubble formation and melt pool dynamics was studied via in-situ synchrotron X-ray imaging and numerical simulation. The formation, escape, and retention of bubbles during deposition process were quantitatively analyzed. Results show that the number of introduced and residual bubbles increased with increasing laser power (from 300 W to 400 W), but the residual bubble ratio initially increased and subsequently decreased. This trend is attributed to the enhancement of both Marangoni flow and heat input caused by increasing laser power. The stirring effect induced by the Marangoni flow not only enhances the introduction of bubbles but also facilitates their escape. Meanwhile, higher heat input prolonged the retention time of the melt pool, which benefits bubble escape. The residual bubble number was high under slow scanning speed of 500 mm/min, which can be attributed to the sustained downward inner gas pressure exerted by the laser beam on the bubbles.</div></div>","PeriodicalId":19511,"journal":{"name":"Optics and Laser Technology","volume":"192 ","pages":"Article 113611"},"PeriodicalIF":4.6,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144680066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, the present study develops a spectral calibration model based on Mie scattering theory and analyses the causes of spectral drift. By systematically analysing the diffuser plates and optical structures within the calibration system, it is found that the oblique angles of the calibration light source and the particle sizes of the diffuser plates are critical factors influencing calibration accuracy.

By exploiting the self-rotation of cells to capture multi-angle projection images, this method facilitates label-free, quantitative, and isotropic reconstruction of the refractive index (RI) distribution, offering a transformative perspective for high-throughput, three-dimensional (3D) cell analysis. Nevertheless, a significant challenge persists: achieving a balance between high throughput and sufficient sampling angles to ensure accurate RI reconstruction. To address the sparse-angle limitations imposed by high-throughput conditions, we proposed a physics-inspired neural network for RI distribution reconstruction under missing-angle scenarios. Our approach employed the filtered back-projection algorithm to reconstruct an initial RI distribution as the network’s input. Subsequently, a wave propagation model was used to compute the transmitted light field corresponding to the estimated RI distribution, which is compared to the experimentally measured light field to define the loss function. Through iterative training, the network refined the RI distribution until it converged to the reference reconstruction, without requiring any external training datasets, thereby enhancing the method’s versatility. We validated this approach by reconstructing the RI distributions of vacuole-containing ovarian cancer cells and colon cancer cells internalizing carbon nanoparticles, using 25%, 50%, and 75% of the total acquired phase images.
