First quantitative microwave calorimeter (Energy, 2023)

We are happy to share our new research describing a novel application of microwave technology in the field of material analysis, “Microwave calorimeter for dielectric and thermal analysis of materials,” published in January 2023 in Energy (Elsevier).

Our article presents a unique method for microwave processing and measurement of dielectric and thermal properties of materials as a function of temperature.

The increasing energy demand has brought the advent of new materials with advanced properties, including the materials that generate, store and transport energy, along with new processing techniques (microwaves, solar energy, etc.). This type of material requires the development of new testing instruments and measurement methods capable of highlighting their unique properties and potential to store energy. …

New insights in microwave-driven redox transformations (Materials Horizons, 2023)

We are pleased to present the scientific work “Modulating redox properties of solid-state ion-conducting materials using microwave irradiation“, published in October 2023 in Materials Horizons, a Royal Society of Chemistry publication.  

The research addresses the industrial demand for efficient, low-carbon technologies by exploring additional significant findings from our laboratory regarding the recently discovered use of microwaves as an effective reducing agent for solid-state ion-conducting materials (SSIMs), holding promise for various applications, including gas depuration, energy storage, and hydrogen generation.   

The study examines the dynamics and physicochemical dependencies of microwave-induced redox transformations in materials such as gadolinium-doped ceria (CGO) and yttria-stabilized zirconia (8YSZ). Microwave processing promotes oxygen-vacancy formation and oxygen-surface exchange at significantly lower temperatures than traditional techniques.    …

A revolution in energy research, from microwaves to hydrogen

The technology developed by researchers from the ITACA and ITQ institutes makes it possible to transform electric energy into hydrogen or chemical products, solely using microwaves.

A team of researchers from the Polytechnic University of Valencia and the Spanish National Research Council (CSIC) has discovered a new method that makes it possible to transform electricity into hydrogen or chemical products solely using microwaves – without cables and without any type of contact with electrodes.

This represents a revolution in the field of energy research and a key development for the process of industrial decarbonisation, as well as for the future of the automotive sector and the chemical industry, among many others. The study has been published in the latest edition of Nature Energy, where the discovery is explained.

Microwave-driven exsolution (ACS nano, 2023)

Discover the innovative approach to creating metallic nanoparticles with our latest study, ” Microwave-Driven Exsolution of Ni Nanoparticles in A-Site Deficient Perovskites,” published in November 2023 in ACS Nano, American Chemical Society.

Exsolution has emerged as a promising method for generating metallic nanoparticles, surpassing traditional deposition methods such as impregnation in terms of robustness and stability.

Here, we demonstrate the exsolution of catalytically active Ni nanoparticles driven by microwaves in the absence of hydrogen or low pressures. With the aid of microwaves, we were able to generate these exsolved nanoparticles at milder temperatures and shorter exposure times than conventional thermal exsolution.

Microwave Technology for Sintering High-Quality Materials (ACT, 2014)

Discover the potential of microwave technology in material sintering with our study, ” Microwave, Spark Plasma and Conventional Sintering to Obtain Controlled Thermal Expansion β-Eucryptite Materials,” published in July 2014 in the International Journal of Applied Ceramic Technology.

In this work, lithium aluminosilicate was fabricated by three different methods: conventional, spark plasma and microwave sintering, from 1200 to 1300°C.

Microwave technology developed by DIMAS made possible to obtain fully dense glass-free lithium aluminosilicate bulk material (>99%) with near-zero and controlled coefficient of thermal expansion and excellent mechanical properties (7.1 GPa of hardness and 110 GPa of Young’s modulus).
