Yb3+-doped rod-type amplifiers with local adiabatic tapers for peak power scaling and beam quality improvement

The use of short local tapers in large mode area fiber amplifiers is proposed for peak power scaling while maintaining good beam quality. To avoid modal distortions, the powder-sintering (REPUSIL) method...

Common mistakes in cross-validating classification models

The common mistakes of cross-validation (CV) for the development of chemometric models for Raman based biological applications were investigated. We focused on two common mistakes: the first mistake occurs...

Multimodal image analysis in tissue diagnostics for skin melanoma

Early diagnosis is the corner stone for a successful treatment of most diseases including melanoma, which cannot be achieved by traditional histopathological inspection. In this respect, multimodal imaging,...

Raman microspectroscopy a promising tool for identifying the causative microorganism(s) in patient urine sample and detecting contaminants

Emerging young vibrational spectroscopists

This special issue of Vibrational Spectroscopy focuses on prominent young vibrational spectroscopist undertaking an impressive range of research whose work has the potential to influence future directions...

Quasi-linearly polarized hybrid modes in tapered and metal-coated tips with circular apertures: understanding the functionality of aperture tips

In this study, we investigate analytically and experimentally the roles of quasi-linearly polarized (LP),hybrid, plasmonic and photonic modes in optical detection and excitation with aperture tips in scanning...

A standardized in vitro blood-brain barrier model for studying nanocarrier transport at biological barriers

European Superconductivity News Forum

The sensor, called herein GHS, is based on a dc SQUID connected to a SQIF that amplifies the voltage from the first stage SQUID. The SQIF consists of an array of SQUIDs with various inductances, facilitating...

Raman and infrared spectroscopy differentiate senescent from proliferating cells in a human dermal fibroblast 3D skin model

Senescent cells contribute to tissue aging and dysfunction. Therefore, detecting senescent cells in skin is of interest for skin tumor diagnostics and therapy. Here, we studied the transition into senescence...

Anti-biofilm strategies of amorphous and crystalline pure titanium dioxide nanoparticles: an overview

Microbes often form surface attached communities called biofilms mainly to get protected against antimicrobials and other environmental stresses. This is a major problem in medical, environmental and industrial...
