Intra-tracheal photoacoustic endoscopy for in vivo tracking of inhaled nano-adjuvants

Chaohao Liang, Fengbing He, Xue Wen, Yibo Tang et autres

Nano-adjuvants as key vaccine components can more efficiently activate systemic immunity via inhalation. However, assessing the dynamic process of nano-adjuvant translocation across tracheal layers in vivo using conventional methods remains challenging. In this study, an intra-tracheal photoacoustic endoscopy (IT-PAE) system equipped with …

Micro-texture-mediated dynamic hetero-deformation enabling high strength-ductility in a dilute Mg-Al-Ca-Mn alloy

Siqing Wang, Tong Wang, Shi-Chao Wang, Jiarui Chen et autres

Micro-texture design of hard-/soft-oriented grains improves Mg alloys' mechanical properties, while strength-ductility trade-off persists due to insufficient early-stage strengthening from soft-oriented grains and later-stage strain coordination in hard-oriented grains. Here, a TD-spread basal-textured dilute Mg-1.27Al-0.38Ca-0.45Mn alloy architected by uniformly-mixed basal-/TD-/random-oriented grains was …

Effect of hydrogen on oxidation of Fe-20Cr-(1Si, 2Mn or 2Al) alloys in water vapour at 650 °C

Jiarui Chen, Jianqiang Zhang, David J. Young

Hydrogen production and utilisation involve H 2 O(g) at high temperatures. However, the effect of hydrogen on chromia-forming heat resistant alloys in H 2 O is still unclear. In this work, Fe-20Cr and Fe-20Cr-(1Si, 2Mn or 2Al) (wt%) were exposed in Ar-xH …

Range Sidelobe Iterative Suppression Algorithm for Extended Target with Non-Grid Multiple Scattering Points

Jing Xu, Yanan Zhang, Jindong Zhang, Jiarui Chen

This paper concentrates on extended targets to suppress high sidelobes in non-grid multiple scattering points. Notice that the problem essentially resolves the high sidelobes of the non-grid multiple scatterers after locating positions; we proposed a novel iterative algorithm based on an adaptive …
