In the last few years, high-entropy oxides (HEOs), a new class of single-phase solid solution materials, have attracted growing interest in both academic research and industry for their great potential broad range applications. This work investigates possibility producing pure HEOs with spinel structure (HESOs) under milder conditions (shorter heat treatments at lower temperatures) than standard solid-state techniques, thus reducing environmental impact. For this purpose, large set HESOs was...
Haematite (α-Fe2O3) nanostructures were synthesized via a Pechini sol-gel method (PSG) and an electrospinning (ES) technique. Their texture morphology investigated by scanning transmission electron microscopy. α-Fe2O3 nanoparticles obtained the PSG method, whereas fibrous structures consisting of interconnected particles through ES The crystallinity was also studied means x-ray diffraction Raman spectroscopy. Gas-sensing devices fabricated printing samples on ceramic substrates provided with...
The availability of low-cost, high-performing sensors for carbon dioxide detection in the environment may play a crucial role reducing CO2 emissions and limiting global warming. In this study, calcium-doped zinc oxide nanofibres with different Ca to Zn loading ratios (1:40 or 1:20) are synthesised via electro-spinning, thoroughly characterised and, first time, tested as an active material dioxide. results their characterisation show that highly porous fibres consist interconnected grains...
Abstract Self‐supporting paper‐like membranes consisting of carbon/germanium dioxide (C/GeO 2 ) fibers are prepared via electrospinning solutions with different germanium load (2.50−4.25 wt%), followed by carbonization at 550−700 °C, and evaluated as anode materials in lithium ion batteries. The investigation the physicochemical properties several characterization techniques shows that, expected, increasing temperature better graphitized less nitrogen‐rich C obtained, containing Ge 0 and/or...
In the last years, hematite has been utilized in a plethora of applications. High aspect-ratio nanohematite and hematite/silica core-shell nanostructures are arousing growing interest for applications exploiting their magnetic properties. Atomic layer deposition (ALD) is here to produce SiO2-coated α-Fe2O3 nanofibers (NFs) through two synthetic routes, viz. electrospinning/calcination/ALD or electrospinning/ALD/calcination. The number ALD cycles (10-100) modulates coating thickness, while...
Electrosorptive desalination is a very simple and appealing approach to satisfy the increasing demand for drinking water. The large-scale application of this technology calls development easy-to-produce, cheap highly performing electrode materials identification tailoring their most influential properties, as well.

Self-standing and flexible paper-like electrodes consisting of nano-sized Co3O4 nanoparticles encapsulated in nitrogen-doped graphite-like carbon fibers are synthesized by electrospinning followed thermal treatment. Several studies have recently reported that encapsulating metal oxides display conversion reaction, such as manganese, iron cobalt oxides, within the three-dimensional network electrospun allows to remarkably improve performances lithium-ion batteries. In present work, we...
Abstract Sodium-ion batteries (SIBs) potentially represent a more sustainable, less expensive and environmentally friendly alternative to lithium-ion batteries. The development of new low-cost, non-toxic, highly performing electrode materials is the key point for SIB technology advances. This study develops basic life cycle assessment (LCA) model evaluation production by electrospinning iron (III) oxide-based fibers be used as anode in SIBs. Indeed, it has been recently demonstrated that...
Synthetic dyes, dispersed in water, have harmful effects on human health and the environment. In this work, Ti and/or Zn oxide nanofibers (NFs) with engineered architecture surface were produced via electrospinning followed by calcination. Calcination subsequent cooling operated at fast rates to generate porous NFs capture centers reduce recombination rate of photogenerated charges. After morphological microstructural characterisation, comparatively evaluated as photocatalysts for removal...
Abstract Water electrolysis fed by renewable energy is the foremost technology to generate green hydrogen. Relevant challenges regard decrease of precious metal loadings and performance enhancement while maintaining cutting edge efficiency. Next generation electrolysers must provide dynamic behaviour improve grid-balancing services thus integrate with grid intermittent sources. The HPEM2GAS project developed a low-cost optimised PEM electrolyser for management through both stack balance...
Presently, adsorption/absorption is one of the most efficient and cost-effective methods to clean oil spill up. In this work, self-supporting paper-like fibrous membranes were prepared via electrospinning carbonisation at different temperatures (500, 650 or 800 °C) by using polyacrylonitrile/polymethylmethacrylate blends with a mass ratio two polymers (1:0, 6:1 2:1). After morphological microstructural characterisation, as-produced evaluated as sorbents immersion in vegetable (sunflower seed...
