Published in 2023 at "Advanced healthcare materials"

DOI: 10.1002/adhm.202300541

Abstract: Thanks to deep penetration and high resolution, the second near-infrared window (NIR-II, 1000nm-1700 nm) fluorescence imaging is expected to gain favor in clinical applications, including macroscopic imaging for cancer diagnosis and microangiography for vascular-related disease diagnosis. Nevertheless,… read more here.

Published in 2022 at "Journal of Biophotonics"

DOI: 10.1002/jbio.202200122

Abstract: Oblique illumination imaging can significantly improve the contrast of transparent thin samples. However, in traditional oblique illumination methods, either the condenser is offset or a block is added to the condenser, which makes it complicated… read more here.

Published in 2018 at "Journal of Mathematical Sciences"

DOI: 10.1007/s10958-018-3877-y

Abstract: The spectral problem for an infinite periodic medium perturbed by a compact defect is considered. For a high contrast small ε-size periodicity and a finite size defect we consider the critical ε2-scaling for the contrast.… read more here.

Published in 2018 at "Science China Chemistry"

DOI: 10.1007/s11426-018-9365-x

Abstract: In nanoscience, molecular switches have played a significant role to deliver different control abilities to practical functions, whereas high-contrast luminescence switchable manipulation at nanoscale is still limited. Since the tuning for emission behavior with high… read more here.

Published in 2019 at "Journal of Mathematical Analysis and Applications"

DOI: 10.1016/j.jmaa.2018.12.014

Abstract: We analyse a problem of two-dimensional linearised elasticity for a two-component periodic composite, where one of the components consists of disjoint soft inclusions embedded in a rigid framework. We consider the case when the contrast… read more here.

Published in 2019 at "Journal of the Mechanics and Physics of Solids"

DOI: 10.1016/j.jmps.2018.08.024

Abstract: Abstract We consider elastic waves in a two-dimensional periodic lattice network of Timoshenko-type beams. We show that for general configurations involving certain highly-contrasting components a high-contrast modification of the homogenization theory is capable of accounting… read more here.
