High-Throughput Synthesis of Uniform Silver Seed Particles by a Continuous Microfluidic Synthesis Platform

Controlled silver particle geometries require at least a synthesis in two steps which strongly differ in their reaction kinetics. For the first step, the very fast seed formation, chaotic advection-based...

Simion Simon: An appreciation

Temperature–pressure induced nano-structural inhomogenities for vortex pinning in bulk MgB2 of different connectivity

Higher critical current densities, jc, (up to 1.6–0.15 MA/cm2 at 10–35 K) at low magnetic fields can be attained in MgB2-based materials, if a high manufacturing temperature (1050 _C) is used, while...

Visualized method of chemical enhancement mechanism on SERS and TERS

We review our developed visualization method of charge transfer (CT) for chemical enhancement mechanism on surfaceenhanced Raman scattering (SERS) and tip-enhanced Raman spectroscopy (TERS). Firstly, we...

Extinction properties of ultrapure water down to deep ultraviolet wavelengths

We report on the optical extinction properties of the clearest ultrapure water measured so far within the wavelength interval between 181 nm and 340 nm (TOC level: 2.6 ± 0.7 ppb, specific conductivity:...

Thermal stresses and cracking behavior during laser crystallization of silicon on glass for thin film solar cells

During the preparation of silicon thin film solar cells on glass substrates by diode laser induced liquid phase crys-tallization (LPC) cracking is an issue. This is due to thermal stresses caused by high...

Nonlinear refractive index study on SiO2-Al2O3-La2O3 glasses

The nonlinear refractive index n2 of SiO2-Al2O3-La2O3 (SAL) glasses of 10 to 24 mol% La2O3 is determined via Z-scan technique at 800 nm in the sub-100 fs time regime. n2 (5.8 to 9.3 × 10−16 cm2/W) correlates...

As2S3–silica double-nanospike waveguide for mid-infrared supercontinuum generation

A double-nanospike As2S3–silica hybrid waveguide structure is reported. The structure comprises nanotapers at input and output ends of a step-index waveguide with a subwavelength core (1 μm in diameter),...

A semi-analytical model for the approximation of plasmonic bands in arrays of metal wires in photonic crystal fibers

We present a highly efficient semi-analytical and straightforward-to-implement model for the determination of plasmonic band edges of metallic nanowire arrays inside photonic crystal fibers. The model...

Multimodal nonlinear imaging of atherosclerotic plaques differentiation of triglyceride and cholesterol deposits

Cardiovascular diseases in general and atherothrombosis as the most common of its individual disease entities is the leading cause of death in the developed countries. Therefore, visualization and characterization...
