A polarization-independent and omnidirectional nearly perfect absorber in the visible region has been proposed. The is two-layer structure consisting of a subwavelength metal grating layer embedded high refractive index lossless dielectric on substrate. Extraordinary optical absorption with peaks over 99% can be achieved whole for both TM TE polarization. This attributed to cavity mode (CM) resonance caused by coupled surface plasmon polaritons (SPP). Through adjusting thickness, peak tuned...
The role of spatial confinement in nanosecond laser-induced Cu plasma is investigated by optical emission spectroscopy, fast imaging and shadow imaging. Significant spectral enhancements the atomic ionic emissions are observed when two Al-plates used to confine plasma. experimental results show that parameters such as temperature, electron density, signal-to-background ratio all increase presence confinement, distance walls critical for enhancement, enhancement time duration, delay at which...
In this work, LIBS technology combined with the LASSO–LSSVM regression model was used to improve detection ability of minor elements in Al–Cu–Mg–Fe–Ni aluminum alloy.
In this paper, we report a new power-free multifunctional soft contact lens device that can measure intraocular pressure (IOP), achieve extended drug delivery in situ, and detect glaucoma biomarkers, all within the same device. Experiments demonstrate sensor Interleukin 12p70, one possible biomarker for glaucoma, concentration as low 2 pg/ml artificial tears. The sustained release of last up to 30 days. ex vivo tests using cadaver pig eyes, detected IOP range 10-50 mmHg with excellent repeatability.
The effects of inter-pulse delay on the quantitative analysis femtosecond-nanosecond double-pulsed laser-induced breakdown spectroscopy (fs-ns DP-LIBS) for assessing Pb in soil have been systematically studied this work. A femtosecond pulse laser was focused to produce a filament, which used ablate sample and an appreciable amount aerosol particles ejected from surface at low density. Scattering images were obtained, found 800 µs. After delay, nanosecond Nd:YAG re-ablated obtained spectral...
In this paper the spectral enhancement of laser-induced breakdown spectroscopy (LIBS) for copper plasma in presence a magnetic field is investigated and temporal- spatial-resolved emission spectra are analyzed. Experimental results show that atomic ion have been enhanced external field. addition, Cu I 521.82 nm intensity evolution with delay time appears to double peak around 2 μs, but II 507.57 has sharp decrease because electron-atom three body recombination process. The temperature...
Combined laser-induced breakdown spectroscopy (LIBS) and hyperspectral imaging (HSI) with machine learning algorithms can be used to identify rice quality the place of origin production rapidly accurately.
Dye-sensitized solar cells (DSSCs) were fabricated using TiO2 nanotube arrays (NTAs) as the photoanodes, which adhered onto transparent conducting glass substrates by a graphene-TiO2 composite paste. The effect of graphene contents on DSSC performance was investigated adjusting ratios to in It found that optimized efficiency 6.29 % achieved at suitable loading concentration 0.1 wt%. Furthermore, it demonstrated enhancement due promoting electron transfer. However, can also absorb light,...
Abstract Discarded aluminum alloys are a form of recyclable metal materials, and their classification identification highly important. In this work, laser‐induced breakdown spectroscopy (LIBS) technique combined with principal component analysis (PCA) least‐squares support‐vector machine (LSSVM) algorithm were used to classify identify five types alloys. Exploratory by PCA was performed achieve better segregation. The accuracy the (SVM) LSSVM for alloy 98.33% 100%, respectively. higher...

The microfluidic interface of the ensures samples to be automatically delivered on even without any external pumps, making it potentially operation field or source-limited settings if sample-preparation component is integrated same chip. arrayed can functionalized aptamers specific different hormones, hence this screen...
Abstract Although all‐inorganic perovskite quantum dots (QDs) have outstanding optoelectronic properties, they tend to poor stability in air and water, at high temperatures, under light irradiation. Herein, a glow discharge plasma process incorporating real‐time situ diagnosis is designed for efficient encapsulation improve the of CsPbBr 3 QD films. An ammonia/silane which has less destructive effects on QDs used plasma‐enhanced chemical vapor deposition produce a‐SiN x :H QDs. The...

We present an effective method to suppress the hole overflow in Si quantum dots-based silicon nitride (SiN) light-emitting diodes (LEDs) by employing nanocrystalline (nc-Si) layer as blocking inserted between SiN luminescent active and p-Si anode. The proposed devices exhibit strong white light emission under forward bias conditions. In comparison LEDs without nc-Si interlayer, a significant enhancement of more than 200% efficiency is achieved from devices. increment EL found strongly depend...
