Raman spectroscopic imaging for in vivo detection of cerebral brain metastases

Double-element metamaterial with negative index at near-infrared wavelengths

We present the realization of a metamaterial that combines double cut wires and continuous wires in its unit cell. This double-element geometry together with the applied layer-by-layer fabrication technique...

Can Thermotunneling Improve the Currently Realized Thermoelectric Conversion Efficiency?

Silicon Nanowire-Based Solar Cells on Glass: Synthesis, Optical Properties, and Cell Parameters

Silicon nanowire (SiNW)-based solar cells on glass substrates have been fabricated by wet electroless chemical etching (using silver nitrate and hydrofluoric acid) of 2.7 μm multicrystalline p+nn+ doped...

Characterization of lipid extracts from brain tissue and tumors using Raman spectroscopy and mass spectrometry

Brain tissue is characterized by high lipid content. The amount of lipids decreases, and its composition changes in the most frequent primary brain tumor, the glioma. Scope of the current paper was to...

Ferrofluids of magnetic multicore nanoparticles for biomedical applications

For a variety of magnetically based biomedical applications, it is advantageous to use sedimentation stable suspensions of relatively large (d >20 nm) magnetic core–shell nanoparticles. Water-based...

Magnetic nanoparticles coated with carboxymethylated polysaccharide shells-Interaction with human cells

The interaction of magnetic core shell nanoparticles with living cells depends on the structure of the shell. In this paper we demonstrate a strong difference in the cell–nanoparticle interaction depending...

Effect of supplementary manganese on the sporulation of Bacillus endospores analysed by Raman spectroscopy

It is a common practice in microbiology to induce and accelerate sporulation of spore-forming bacteria by adding small amounts of divalent manganese to the cultivation medium. By micro-Raman spectroscopy...

Bragg Grating Inscription in GeO2-Doped Microstructured Optical Fibers

Inscription of Fiber Bragg Grating Arrays in Pure Silica Suspended Core Fibers

Fiber Bragg grating (FBG) arrays in pure silica fourleaf-clover-shaped suspended core fibers were inscribed with two-beam interference and a deep UV femtosecond laser source. The target fibers are pure...
