Poor aspect profiles of plasmonic lithography patterns are suffering from evanescent waves' scattering loss in metal films and decaying exposure photoresist. To address this issue, we experimentally report cavity lens to enhance profile resolution lithography. The depth half-pitch (hp) 32 nm resist is improved up 23 nm, exceeding the reported sub-10 photoresist depth. then transferred bottom with 80 using hard-mask technology etching steps. hp 22 demonstrated. enhancement mainly attributed...
bitterant prediction received the considerable attention due to expensive and laborious experimental-screening of bitterant. In this work, we collect fully experimental dataset containing 707 bitterants 592 non-bitterants, which is distinct from or partially hypothetical non-bitterant used in previous works. Based on dataset, harness consensus votes multiple machine-learning methods (e.g., deep learning etc.) combined with molecular fingerprint build bitter/bitterless classification models...
In complex agricultural landscapes, especially with limited sample sizes, current instance segmentation techniques often grapple defining clear boundaries, thereby compromising accuracy. To mitigate this challenge, our research proposes enhancements through quantitative comparisons and the incorporation of SAM model to bolster networks. Specifically, we have formulated SAM+Mask2Former SAM+Mask R-CNN by adopting SAM's feature encoder as foundational backbone. Further refinement is...
For near-field imaging optics, minimum resolvable feature size is highly constrained by the diffraction limit associated with illumination light wavelength and air distance between devices objects. In this study, a plasmonic cavity lens composed of Ag-photoresist-Ag form incorporating high spatial frequency spectrum off-axis (OAI) proposed to realize deep subwavelength far beyond limit. This approach benefits from resonance effect wavevector shifting behavior via OAI, which remarkably...
Interference lithography is an important method for fabricating periodical nano-structures. Its resolution, however, limited with the minimum period being half wavelength of light due to diffraction limit. In this study, we presented bulk plasmon polariton (BPP) interference resolution far beyond As a demonstrative result, line pattern 35 nm half-period (about 1/10 laser) over large area (20 × 20 mm) was achieved in experiment. The break limit arises from exciting BPP modes high kx spatial...

Cement-stabilized macadam materials are widely utilized as semi-rigid base in road construction. However, conventional cement-stabilized (CCSM) bases often develop shrinkage cracks during early construction and maintenance due to variations humidity temperature. Shrinkage can subsequently result reflective the asphalt pavement, significantly reducing overall service life of road. This study systematically evaluates mechanical properties large-size (LSCSM). Initially, mix proportion for LSCSM...

Interference lithography based on surface plasmon polaritons has been proven to break the diffraction limit and deliver high imaging resolution. However, most previously reported studies suffer from inflexible pattern pitch for a certain structure ascribed fixed excitation mode, which limits applications in micro-/nano- fabrications. In this work, large area deep subwavelength interference with tunable period bulk (BPPs) is proposed. By simply tuning incident angle, spatial frequencies of...
