Chemical Upcycling of PET Waste towards Terephthalate Redox Nanoparticles for Energy Storage
(MDPI, 2021-11-03)
Over 30 million ton of poly(ethylene terephthalate) (PET) is produced each year and no more than 60% of all PET bottles are reclaimed for recycling due to material property deteriorations during the mechanical recycling ...
Organic batteries based on just redox polymers
(Elsevier, 2021-11)
[EN]Redox-active polymers have gained interest as environmentally friendly alternative to inorganic materials in applications such as electrodes in lithium-ion batteries. All-polymer batteries were first disregarded with ...
Innovative Polymers for Next‐Generation Batteries
(Wiley, 2020-01-23)
Lithium-ion batteries are part of modern life, being present in daily-used objects such as mobile phones, tablets, computers, watches, sport accessories, electric scooters, and cars. The next-generation batteries require ...
Single- Versus Dual-Ion UV-Cross-Linked Gel Polymer Electrolytes for Li–O2 Batteries
(Americal Chemical Society, 2021-01-04)
Lithium-O2 batteries represent one of the most appealing candidates for battery electric vehicles (BEV) due to its remarkable theoretical high energy density, similar to fossil fuels. Solid polymer electrolytes represent ...
A trade-off between ligand and strain effects optimizes the oxygen reduction activity of Pt alloys
(RSC, 2022-10-20)
To optimize the performance of catalytic materials, it is paramount to elucidate the dependence of the chemical reactivity on the atomic arrangement of the catalyst surface. Therefore, identifying the nature of the active ...
Enhanced Charge Transfer Kinetics for the Electroreduction of Carbon Dioxide on Silver Electrodes Functionalized with Cationic Surfactants
(Wiley, 2022-12-09)
Cationic ammonium surfactants can be used together with a suitable catalyst to enhance the electroreduction of carbon dioxide (CO2RR). However, the underlying reasons for the improvements are not yet well understood. In ...
Tailoring of Magnetic Softness and Magnetoimpedance of Co-Rich Microwires by Stress Annealing
(Wiley, 2021-06)
glass-coated microwires are provided. As-prepared microwire presents linear hysteresis loops, moderate GMI ratio with double-peak magnetic field dependence and low coercivity (4 A m(-1)), typically observed for wires with ...
Fabrication and Magneto-Structural Properties of Co2-Based Heusler Alloy Glass-Coated Microwires with High Curie Temperature
(MDPI, 2022)
[EN] In this work, we were able to produce Co2FeSi Heusler alloy glass-covered microwires with a metallic nucleus diameter of about 4.4 µm and total sample diameter of about 17.6 μm by the Taylor–Ulitovsky Technique. This ...
Review of Helical Magnetic Structures in Magnetic Microwires
(MDPI, 2022-07-23)
We provide an overview of the helical magnetic structures in magnetic microwires. Having analyzed the experimental data describing the magnetic behavior of magnetic microwires since the 1990s, we found indirect evidence ...
Development of Magnetically Soft Amorphous Microwires for Technological Applications
(MDPI, 2022-01-07)
Amorphous magnetic microwires can be suitable for a variety of technological applications due to their excellent magnetic softness and giant magnetoimpedance (GMI) effect. Several approaches for optimization of soft magnetic ...
