EUROPEAN CONGRESS AND EXHIBITION ON ADVANCED MATERIALS AND PROCESSES - EUROMAT 2021

Renewable feedstocks are an important element in a green economy, as they have the potential to replace fossil fuels in the future. But the production and conversion of renewable fuels, such as biomass, remains a challenge. The natural polymer Lignin is believed to have considerable potential as a renewable feedstock. Lignin can be converted to high quality renewable fuels via catalytic...

One of the intensively developed research areas on intermetallic phases is the use of these chemical compounds as catalyst materials. Promising results of the research conducted so far indicate the applicability of these compounds as a replacement for catalysts based on noble metals. An area of interest is aluminum-based intermetallic compounds, which exhibit high catalytic properties in...

Two sintering processes were chosen as alternative and low-cost fabrication methods for Ni50Mn30Ga20 ferromagnetic shape memory alloy (FeSMA): a simple and single pressing and sintering route and the open die pressing (ODP) process were adopted for the consolidation of NiMnGa powders. The effects of the sintering processes parameters such as sintering time, powders size and cooling method, and...

Two-dimensional materials are the ideal samples for transmission
electron microscopy (TEM) because of their intrinsically thin structure.
Indeed, TEM has been instrumental in revealing the atomic structure of
these materials, including their defects and impurities. More
counter-intuitive is the possibility to also study the corrugation of 2D
materials through TEM. Nevertheless, it has...

TIMs are utilized as contact material between electronic components and the heat sink. The considerably increased power requirements and the continuing trend towards miniaturization in electronic devices lead to an increased performance and desire a suitable characterization of the behavior of TIMS. As a key component in the thermal management of electronic components, TIMs should have high...

Ni-Mn-based metamagnetic shape-memory alloys exhibit outstanding caloric effects in the vicinity of martensitic transformations driven by magnetic fields, uniaxial load or hydrostatic pressure. However, the application in refrigeration devices is hindered by energy losses and/or irreversibilities during cyclic operation which originate from a large inherent thermal hysteresis of the...

The measurement of acoustic vibrational modes is fundamental to the full comprehension of the mechanical properties of nano-objects, since they are connected to the intrinsic characteristics of the material, such as crystallinity, size, shape and elasticity. At the nanoscale, when localized plasmons couple to localized vibrations, the enhancement of inelastic light scattering signals from...

Tin can exist under two different crystalline structures. α-Sn is a cubic crystal and is stable below 13°C. On the other side, β-Sn has the tetragonal phase and is stable above 13°C. In terms of electronic properties, α-Sn is a semimetal and was predicted to possess various topological phases. Moreover, β-Sn is a superconductor with a critical temperature of 3.74K. Interestingly, α-Sn is...

Waste heat originated by industrial and combustive processes or harvested directly from natural heat sources (i.e. sun, geothermal processes, ambient heat etc.) can be converted into electricity by means of thermoelectric modules. These devices use the ability of particular materials to convert heat gradients into voltage by means of the so called Seebeck effect. Thermoelectric generators have...
