Hydrated Deep Eutectic Solvents for the Sustainable Valorization of Textile Waste. [PDF]

ChemSusChem
Hydrated metal‐based deep eutectic solvents (DESs) composed of zinc or calcium chlorides, organic acids, and water were developed as low‐viscosity, room‐temperature‐stable media for the sustainable valorization of cotton waste. These formulations effectively disrupted the cellulose fiber structure and processed microcrystalline cellulose, medical‐grade

Two-Photon Fluorescence and Second-Harmonic Generation Microscopy: Principles and Biomedical Applications. [PDF]

J Biophotonics
Compared with single‐photon methods, TPM enables deep‐tissue imaging using near‐infrared light, with excitation confined to the focal plane, thereby reducing photodamage. SHG microscopy images noncentrosymmetric biological structures such as collagen and myosin without fluorescent labels, offering direct structural contrast.

Twisted Hi-Bi fiber DFB lasers with controllable output polarization [PDF]

, 2012
We demonstrate that single polarization, hi-bi fiber DFB lasers are in general characterized by elliptical state of polarization, due to the in-built fiber birefringence axis rotation.

Wavelength tunable 10-GHz 3-ps pulse source using a dispersion decreasing fiber-based nonlinear optical loop mirror [PDF]

, 2004
We experimentally demonstrate the use of a dispersion decreasing fiber (DDF)-based nonlinear optical loop mirror (NOLM) for the generation of wavelength tunable soliton-like pulses at a repetition rate of 10 GHz.

Continuously wavelength-tunable passband-flattened fiber comb filter based on polarization-diversified loop structure

Scientific Reports, 2017
Continuous wavelength tuning of optical comb filters, which is an essential functionality for flexible signal processing in reconfigurable optical systems, has been challenging in high order filter structures with two birefringent elements (BEs) or more ...
