Doing the Treble: How Three Fluxim Tools Helped Uncover Efficiency Limits in PLECs A study published in Advanced Functional Materials investigated how charge traps impact the efficiency and durability of polymer light-emitting electrochemical cells (PLECs). Conducted by our friend and colleague Matthias Diethelm when he was at Empa, the research examined how electron and hole traps contribute to performance loss and long-term degradation, offering new insights into improving PLEC stability. Here’s how three Fluxim tools played a pivotal role in the findings: 🔍 PAIOS: Uncovering Electron Trap Dynamics Detected electron traps through current and light intensity transients and impedance at 0V, revealing their role in limiting device efficiency. ✨ Phelos: Tracking Emitter Position Used angular-dependent electroluminescence (EL) measurements to track emitter positions, uncovering how charge injection and EDL relaxation affect performance. 📊 Setfos: Simulating Device Behavior Simulated luminance, trap densities, and emitter dynamics, providing critical insights into the experimental results and validating degradation mechanisms. Key Takeaway: The study revealed how charge traps hinder PLEC performance, highlighting the need for innovative solutions to overcome these challenges.

#Selectedpapers in #Batteries_MDPI in topic "Redox Flow Batteries and Solid-State Batteries" "NASICON-Type Li1+xAlxZryTi2−x−y(PO4)3 Solid Electrolytes: Effect of Al, Zr Co-Doping and Synthesis Method" 🔗 Read the full article: https://brnw.ch/21wLmD1 👉 Check out more papers in topic "Redox Flow Batteries and Solid-State Batteries": https://brnw.ch/21wLmD2 Abstract Replacing liquid electrolytes with solid-state conductors is one of the key challenges to increasing the safety and energy density of next-generation Li secondary batteries. In this work, the NASICON-type Li1+xAlxZryTi2−x−y(PO4)3 with 0 ≤ x, y ≤ 0.2 solid electrolytes were synthesized using solid-state and sol-gel techniques at various sintering temperatures (800, 900, and 1000 °C). Their morphology and conducting properties were studied to determine the optimal dopant content and synthesis method. Li1.2Al0.2Zr0.1Ti1.7(PO4)3 and Li1.1Al0.1Zr0.2Ti1.7(PO4)3 prepared at 900 °C using a solid-state reaction exhibit the highest total conductivity at 25 °C (7.9 × 10−4 and 5.4 × 10−4 S cm−1, respectively), which is due to the optimal size of lithium transport channels, as well as the high density of these samples. The potential profile of Li|Li1.2Al0.2Zr0.1Ti1.7(PO4)3|Li cells was retained during cycling at a current density of 0.05 mA cm−2 for 100 h, indicating a high interfacial Li metal/electrolyte stability.

This study introduces a novel polysiloxane-based light-responsive liquid crystal elastomer (LCE) with donor–acceptor Stenhouse adduct (DASA) side-chains, synthesized using a late-stage functionalization method. This new approach maintains the molecular alignment achieved by the traditional Finkelmann method, enabling the creation of well-aligned LCE films ranging from 400 µm to 5 mm thick. The LCEs exhibit 2D planar actuation and complete bleaching under low-intensity visible light (100–200 mW cm−2), and bending followed by contraction under higher-intensity light (300 mW cm−2). These responses are repeatable, with the study highlighting how light intensity and heat generation affect DASA's photothermal equilibrium and photoresponsive behavior. This work paves the way for advanced LCE actuators beyond thin films and UV-light dependence. Read more details: https://lnkd.in/eBebW7Fi #polymerscience #actuators

pE-4000 from CoolLED The CoolLED pE-4000 is designed specifically with microscopy core facilities and high end researchers in mind. For these groups a number of questions may arise when deciding upon a light source; the challenge of serving multiple microscope users with varying requirements now and in the future, where fluorophore usage and therefore excitation wavelengths may yet be unknown. Whilst other possible solutions boast up to 6 or 7 wavelengths and generally cover the traditional visible range, the pE-4000 is delivered with 16 wavelengths from 365nm to 770nm. This means that there is never a compromise when selecting the wavelength to use and people are prepared for the increasing move to NIR dyes. Type: Light Sources Applications: Medical/Clinical Science, Life Science, Material Science Wavelengths: 16 Channels: 4 Spectral Coverage: 365 - 770 nm Removable inline excitation filters: 4 Control Options: Pod,software,TTL,analogue Light Delivery: LLG or fibre optic
