A Generalized Automated Framework for Thermal Characterization: From Bulk Materials to Complex Heterostructures

Small, EarlyView.
An automated MATLAB framework for inverse photoacoustic analysis enables precise thermal characterization of complex multilayer films. Application to electrodeposited CuxSe reveals a stoichiometry‐dependent thermal conductivity governed by lattice anharmonicity, not grain‐size scattering, in these superionic materials. ABSTRACT Precise determination of

Optical‐controlled magnon transport based on spin crossover switched molecular magnets

Smart Molecules, EarlyView.
A cyanide‐bridged W(V)–Fe(II) spin‐crossover single crystal was integrated into a magnon transport device, enabling reversible optical control of magnon transport through photo‐switched spin states. Abstract Molecule‐based devices that combine the advantages of fast time response and extremely low manipulation/transmission energy consumption of light ...

Shared and specific molecular mechanisms of proteasome inhibitors in chemotherapy‐induced peripheral neurotoxicity

British Journal of Pharmacology, EarlyView.
This study compares the molecular mechanisms of chemotherapy‐related peripheral neurotoxicity of two proteasome inhibitors, bortezomib and carfilzomib, using a multidisciplinary approach to reveal that, alongside shared effects on mitochondria structure and function, the more neurotoxic drug BTZ has specific effects on microtubules and mitochondrial ...

Persistent in vitro nociceptor hyperexcitability and axonal retraction produced by repeated paclitaxel doses

The FEBS Journal, EarlyView.
Repeated paclitaxel exposure causes long‐lasting nociceptor hyperexcitability and axonal retraction in adult sensory neurons. Using a long‐term primary nociceptor culture, we show that hyperexcitability is mediated by sequential upregulation of NaV1.8, TRPV1, TRPA1, and TRPM8 channels.

Photonic-Crystal Fibers

Journal of Lightwave Technology, 2003
Photonic crystal fibers guide light by corralling it within a periodic array of microscopic air holes that run along the entire fiber length. Largely through their ability to overcome the limitations of conventional fiber optics—for example, by permitting low-loss guidance of light in a hollow core—these fibers are proving to have a multitude of ...

Photonic Crystal Fibers challenge

Proceedings of the International Conference on Computer Systems and Technologies and Workshop for PhD Students in Computing, 2009
The paper describes some kinds of Photonic Crystal Fibers and their features. The problems of attenuation of the PCF in connection with their properties and design are discussed. An analytical method for calculating the attenuation and dispersion of the spreading modes of Bragg fibers, represented as a multilayer dielectric structure, is proposed.

Photonic crystal fiber coupler

Optics Letters, 2002
Fiber couplers made with photonic crystal fibers (PCF) are reported. Two types of PCF were fabricated by means of stacking a group of silica tubes around a silica rod and drawing them. The fiber couplers were made by use of the fused biconical tapered method. With a fiber that had five hexagonally stacked layers of air holes, a 33/67 coupling ratio was

Highly Birefringent Photonic Crystal Fibers

Optics and Photonics News, 2000
We report a strongly anisotropic photonic crystal fiber. Twofold rotational symmetry was introduced into a single-mode fiber structure by creation of a regular array of airholes of two sizes disposed about a pure-silica core. Based on spectral measurements of the polarization mode beating, we estimate that the fiber has a beat length of approximately 0.
