Fiber Depolymerization [PDF]

open access: yesBiophysical Journal, 2006
Depolymerization is, by definition, a crucial process in the reversible assembly of various biopolymers. It may also be an important factor in the pathology of sickle cell disease. If sickle hemoglobin fibers fail to depolymerize fully during passage through the lungs then they will reintroduce aggregates into the systemic circulation and eliminate or ...

Recent Advances in Phase-Sensitive Optical Time Domain Reflectometry (Ф-OTDR)

open access: yesPhotonic Sensors, 2021
Phase-sensitive optical time domain reflectometry (Ф-OTDR) is an effective way to detect vibrations and acoustic waves with high sensitivity, by interrogating coherent Rayleigh backscattering light in sensing fiber. In particular, fiber-optic distributed

Detection of nanometer-scale diameter changes in optical fibers with forward stimulated Brillouin scattering [PDF]

open access: yesEPJ Web of Conferences
We investigate the potential of forward-stimulated Brillouin scattering in optical fibers to detect changes of the fiber diameter with nanometer resolution.

Fiber Diffraction without Fibers

open access: yesPhysical Review Letters, 2013
Postprocessing of diffraction patterns of completely randomly oriented helical particles, as measured, for example, in so-called "diffract-and-destroy" experiments with an x-ray free electron laser can yield "fiber diffraction" patterns expected of fibrous bundles of the particles. This will allow "single-axis alignment" to be performed computationally,

Recognition Preference of Rhodamine Derivative Bearing Phthalimido Gly for Hg2+ by UV-Vis and Fluorescence Spectroscopy

open access: yesJournal of Spectroscopy, 2013
An effective Hg2+-specific probe 1 was designed and prepared based on Phthalimido Gly modified rhodamine B. The sensing behavior of probe 1 was studied by UV-Vis and fluorescence spectroscopy.

Fused fiber couplers for fiber photometry

open access: yesCell Reports Methods, 2023
In this issue of Cell Reports Methods, Formozov et al. present an innovative fiber photometry system that uses a fused fiber coupler (FFC) instead of a dichroic mirror to split the excitation and emission light. The FFC-based photometry system is highly flexible and can be easily reconfigured to record from different biosensors.

High-brightness table-top coherent XUV source at 130eV [PDF]

open access: yesEPJ Web of Conferences
We present a highly stable, easy-to-use, table-top coherent XUV source delivering a brightness of >1kW/(mm²sr)/1%BW at 130eV (9.5nm). It is based on high-harmonic generation driven by an ultrastable ytterbium-based fiber laser and a multipass-cell-based ...
