Thulium-doped fiber laser with longitudinally segmented active fiber

open access: yesEighth International Workshop on Specialty Optical Fibers and Their Applications (WSOF 2025)
Nowadays, one of the main challenges of thulium-doped fiber lasers is thermal management. One prospective method to significantly reduce thermal load density along the fiber is using a segmented active fiber or active fiber with a longitudinal gradient of thulium-doping concentration.

Low loss, side bandwidth, low bend sensitivity HC-PBGF for mid-IR applications

open access: yes
Hollow core-photonic bandgap fiber, operating in the spectral region between 3 and 4 µm, is reported. Order of magnitude loss reduction is demonstrated (0.13dB/m) compared to previously reported fibers, combined with very low bend ...

MXenes as a Versatile Platform for High‐Energy‐Density Asymmetric Supercapacitors

open access: yesCarbon Energy, EarlyView.
MXenes with high conductivity and tunable surface chemistry are reviewed as advanced electrodes for asymmetric supercapacitors. MAX‐phase synthesis, surface and interlayer engineering, defect modulation, and composite designs are discussed, highlighting enhanced ion transport, pseudocapacitance, energy density, cycling stability, and sustainable routes

Durable Fuel Cell Cathode Enabled by Pt Embedded Nanoscale Carbon Network via a Scalable Process

open access: yesCarbon Energy, EarlyView.
Platinum nanoparticles embedded nanoscale carbon network (Pt‐e‐Cn) are developed via a scalable flame spray pyrolysis process. Proton exchange membrane fuel cells (PEMFC) employing mesoporous Pt‐e‐Cn cathode electrocatalysts exhibit exceptional durability without compromising performance.

Unveiling the Potential of Metal and Non‐Metal Modified Porous Carbon for the Electrochemical Reduction of CO2

open access: yesCarbon Energy, EarlyView.
Earth‐abundant metal‐ and non‐metal‐modified porous carbons offer a highly tunable platform for electrochemical CO2 reduction. This review shows how electronic interactions, active‐site coordination, pore architecture, and cooperative catalytic effects jointly govern intermediate stabilization, product selectivity, and device‐relevant CO2RR performance.

Increased Insulin Action, Glucose Metabolism and Muscle Function in Supervillin‐Knockout and Supervillin‐Mutant Mice

open access: yesCytoskeleton, EarlyView.
ABSTRACT We here describe mouse models with complementary homozygous Svil mutations. In skeletal muscle, Svil‐Mut mice express the Svil‐encoded N‐terminus fused to the βgal‐neo gene‐trap tag and lack the highly conserved archvillin C‐terminus; Svil‐KO mice lack expression of all known Svil‐encoded proteins; and Svil‐LoxP mice contain loxP sites for ...

Co‐Catalyst/Semiconductor Interface Coupling Design for Efficient Solar‐Driven Photocatalysis

open access: yesEcoEnergy, EarlyView.
Interfacial coupling strength is proposed as a unifying descriptor governing charge‐transfer behavior in co‐catalyst/semiconductor photocatalytic systems. This review establishes a coupling‐strength‐guided framework that correlates interface engineering strategies with charge transport pathways, electronic structure regulation, and photocatalytic ...

Temperature investigation of low SWaP thulium-doped fiber lasers

open access: yesOptics Express
We investigate the temperature dependence of an in-band core-pumped thulium-doped fiber laser with a low SWaP (size, weight, and power) architecture. The temperature investigation is carried out both experimentally and numerically by a simulation model.
