Polydopamine and Its Derivative Materials: Synthesis and Promising Applications in Energy, Environmental, and Biomedical Fields

Since its discovery, the asymmetric Fano resonance has been a characteristic feature of interacting quantum systems. The shape of this resonance is distinctively different from that of conventional symmetric resonance curves. Recently, the Fano resonance has been found in plasmonic nanoparticles, photonic crystals, and electromagnetic metamaterials. The steep dispersion of the Fano resonance profile promises applications in sensors, lasing, switching, and nonlinear and slow-light devices.

Synthesis and Characterization of (Et4N)4(MoS4Cu10Cl12): A Polynuclear Molybdenum-Copper Cluster Containing a Central Tetrahedral MoS4 Encapsulated by Octahedral Cu6 and Tetrahedral Cu4 Arrays.

In this study, nickel-phosphorus (NiP) surface is irradiate by a KrF excimer laser beam. Atomic force microscope and x- ray diffraction are employed to study the surface morphology and the material structure. For laser fluence form 124 mJ/cm2, thin periodic structure morphology is formed in the irradiated region. When laser fluence exceeds 200 mJ/cm2, a microcosmic-smooth ripple morphology is obtained. The period of the second morphology is obviously larger than that of the first morphology. The morphology is dependent on the original surface condition, laser fluence and laser pulse number in the low laser fluence region and only laser fluence and laser pulse number in the high laser fluence region. 1D thermal conduction model is used to predict the temperature rise in the irradiated region. Surface melting is predicted to take place at laser fluence about 200 mJ/cm2. The interaction mechanism between laser beam and NiP surface is proposed based on the theoretical calculation and experiment.© (1997) COPYRIGHT SPIE--The International Society for Optical Engineering.

Excimer laser irradiation on NiP surface

A method for surface metallization on transparent substrate with laser induced plasma deposition was described A laser beam goes through the transparent substrate first and then irradiates on a metal target behind For laser fluence above ablation threshold for the target, the generated plasma flies forward at a high speed to the substrate and induces metal materials deposition on its rear side surface and even doping into the substrate The diffusion distribution of metallic particles was measured with Time of Flight Secondary Ion Mass Spectrometer (TOF-SIMS) Electrically conducting films are formed on the substrate with laser beam scanning The near 1Ω/Square lower resistivity can be formed with precise control of the processing parameters Laser fluence, pulse repetition rate and scanning speed, distance between the substrate and metal target and overlapping of the metal lines This technology can be used to form electrodes, resistors, LCD or electronic circuits on the transparent substrates

Laser-induced diffusion for glass metallization

Creation of arbitrary features with high resolution is critically important in the fabrication of nano-optoelectronic devices. Here, sub-50 nm surface structuring is achieved directly on Sb<sub>2</sub>S<sub>3</sub> thin films via microsphere femtosecond laser irradiation in far field. By varying laser fluence and scanning speed, nano-feature sizes can be flexibly tuned. Such small patterns are attributed to the co-effect of microsphere focusing, two-photons absorption, top threshold effect, and high-repetition-rate femtosecond laser-induced incubation effect. The minimum feature size can be reduced down to ~30 nm (<italic>λ</italic>/26) by manipulating film thickness. The fitting analysis between the ablation width and depth predicts that the feature size can be down to ~15 nm at the film thickness of ~10 nm. A nano-grating is fabricated, which demonstrates desirable beam diffraction performance. This nano-scale resolution would be highly attractive for next-generation laser nano-lithography in far field and in ambient air.
