Here, we present a mean to expand the use of individual metallic nanoparticles two-dimensional plasmonic nanoarrays. An optical detection platform track down localized surface plasmon resonance (LSPR) signals on substrates was built for application A pseudoimage substrate reconstructed from their scattering spectra obtained by scanning user-defined area. The spectral and spatial resolutions system were also discussed in detail. Most importantly, method normalize geometrically different...
The pump-induced group velocity reduction of subnanosecond pulses is calculated and measured in a Ba(NO3)2 solid-state Raman amplifier. 1.197 μm probe with 90 ps duration were generated using Raman-shifted mode-locked Q-switched Nd:YAG laser, propagated through crystal synchronously pumped by 7-ns-long 1.06 pulses. time delay the pulse peak was varying pump intensity compared theoretical calculation up to point where amplified spontaneous emission becomes dominant. maximum found be 105 ps.

Modular chemical process intensification involves the deployment of technology within modular construction processing plants. Process improvements in plant efficiency that drive size and weight reductions equipment. The use smaller, lighter equipment reduces costs leading to lower capital thresholds for pursuing new distributed specialty markets. Micro-scale plate reactors, with high surface-area-to-volume ratios, provide a platform reducing cost reactors due rates heat mass transfer....
This paper demonstrates a laser melting method to produce metal matrix composite with higher thermal conductivity compared 316 L stainless steel using Jettable Cu ink. A novel canister was used control the oxygen level during processing emulate hybrid inkjet-powder bed fusion technique for doping powder precursor The of found be 187% than that steel, while microhardness decreased by 39%. Microstructural results show opportunities further enhance and mechanical properties eliminating...

Abstract This paper explores the production of an oxide dispersion strengthened (ODS) 304L stainless steel microchannel heat exchanger (HX) using a hybrid additive manufacturing process laser powder bed fusion and inkjet printing. The study investigates capabilities economics inkjet-laser (LPBF) evaluates dimensional accuracy, functionality, mechanical properties resulting ODS alloy. effectiveness pressure drop exchangers produced by LPBF tool are also determined. Results show that...
This paper studied the feasibility of a new solution-processed method to manufacture black tungsten nanostructures by laser conversion hexacarbonyl precursor on Inconel 625 substrate under argon atmosphere at ambient pressure. The results show that sublimation can be prevented if decomposition temperature (>170 °C) is achieved using heating method. Three different powers from 60–400 W were used investigate role parameters conversion. It was found lower power 60 resulted in mixture...
Photodynamic therapy (PDT) of cancer works via direct cytotoxicity, causing damage to tumor vasculature and stimulating the body's anti-tumor immune response. PDT outcome depends on parameters used; therefore an in vivo response monitoring system is useful for optimization treatment protocol. The combined use diffuse optical spectroscopy correlation allows us measure tissue oxygen saturation (StO<sub>2</sub>) relative blood flow (rBF) tumors. These were measured before after mouse models...
We present a dual modality device for both low-coherence enhanced backscattering (LEBS) measurement and optical coherence tomography (OCT). They provide complementary information with different resolutions, various applications are demonstrated.
