Ultratrace molecular detections are vital for precancer diagnosis, forensic analysis, and food safety. Superhydrophobic (SH) surface-enhanced Raman scattering (SERS) sensors regarded as an ideal approach to improve detection performance by concentrating analyte molecules within a small volume. However, due the low adhesion of SH surfaces, droplet is prone rolling, making it hard deposit on predetermined position. Furthermore, sediment with very area SH-SERS surface difficult be captured even...
Strong white electroluminescence (EL) from SiN-based devices containing Si nanodots with a density of more than 4.6×1012/cm2 was investigated. The EL illustrates enhanced light emission increasing applied voltage and can be divided into two components, dominant peak at ∼710 nm weak one ∼550 nm, which are close to those the PL spectra optically pumped by 325 488 lines, respectively. Based on characteristics, we propose that band arises band-to-band recombination in dense where quantum...
The control of underwater bubble behavior on a solid surface has great research significance. However, the spontaneous directional transport and collection numerous bubbles remains challenge. A new technique metal mesh with superhydrophobic/hydrophobic properties is demonstrated here, which creates wettability gradient coupled microporous array by means pulsed fiber laser ablation chemical modification aluminum sheet. resultant effectively achieved movement along (superaerophobicity to...
Narrow luminescence lines from self-assembled CdSe quantum dots (QDs) are studied at room temperature by using time-resolved photoluminescence spectroscopy. The narrowest line of the has a full width half maximum 2.1 meV temperature. narrow mainly contribution QDs with longer recombination lifetime to luminescence.
The grounding electrode, buried in the soil, addition to natural corrosion, will occur electrolysis reaction under action of earth current, accelerating corrosion. In this paper, polarization curves copper, carbon steel, galvanized cast iron and graphite are tested by electrochemical curves. After fitting test data, corrosion parameters five kinds ground electrode materials soil simulated solution obtained, rate was according data. rates with or without current calculated compared....
Based on the third-order aberration theory of plane-symmetric optical systems, this paper studies effect aberrations second-order accuracy aperture-ray coordinates and extrinsic kind system; their calculation expressions are derived. The resultant then applied to calculate two design examples soft X-ray vacuum ultraviolet (XUV) systems; images compared with ray-tracing results using SHADOW software validate expressions. study shows that is satisfactory.
