Unidirectional lasing using loss management in a reciprocal fiber ring laser

We report on the observation of a new phenomenon, occurring in a fiber ring laser. It describes the transition from an initially bidirectional emission of a fully reciprocal fiber ring laser to a unidirectional...

Raman18 O-Labeling of Bacteria in Visible and Deep UV-Ranges

Raman stable isotope labeling with 2H, 13C or 15N has been reported as an elegant approach to investigate cellular metabolic activity, which is of great importance to reveal the functions of microorganisms...

Giant persistent photoconductivity in monolayer MoS2 field-effect transistors

Monolayer transition metal dichalcogenides (TMD) have numerous potential applications in ultrathin electronics and photonics. The exposure of TMD-based devices to light generates photo-carriers resulting...

Fiber-based SORS-SERDS System and Chemometrics for the Diagnostics and Therapy Monitoring of Psoriasis Inflammatory Disease in vivo

Localizing the initial excitation – a case study on NiO photocathodes using Ruthenium dipyridophenazine complexes as sensitizers

We report on the localization of the initially excited electronic state within the molecular framework of a series of [Ru(bpy)2dppz]2+ derivatives (bpy:2,20-bipyridine, dppz: dipyrido-phenazine) as sensitizers...

Novel Bio-based Self-healing Ionomers Based on Itaconic Acid Derivates

This article presents novel biobased ionomers featuring self-healing abilities. These smart materials are synthesized from itaconic acid derivates. Large quantities of itaconic acid can be produced from...

Strengthening Interactions with the Membrane Interface through Grafted Aromatic Compounds Produces Extremely Potent HIV-1 Neutralizing Antibodies

Photocathodes Beyond NiO – Charge Transfer Dynamics in a π-Conjugated Polymer Functionalized with Ru Photosensitizers

A conductive polymer (poly(p-phenylenevinylene), PPV) was covalently modified with RuII Complexes to develop an all-polymer photocathode as a conceptual alternative to dye-sensitized NiO, which is the...

Modification of Surface Bond Au Nanospheres by Chemically and Plasmonically Induced Pd Deposition

In this work we investigated methods of modifying gold nanospheres bound to a silicon surface by depositing palladium onto the surfaces of single nanoparticles. Bimetallic Au-Pd nanoparticles can thus...

The impact of episporic modification of Lichtheimia corymbifera on virulence and interaction with phagocytes

Fungal infections caused by the ancient lineage Mucorales are emerging and increasingly reported in humans. Comprehensive surveys on promising attributes from a multitude of possible virulence factors...
