In the last decade five main application pathways have been developed in heterogeneous photocatalysis, including: (i) air treatment, (ii) water treatment, (iii) hydrogen evolution, (iv) CO2 photoconversion, and very recently (v) ammonia synthesis. These technologies are at different levels of maturity, from TRL 3-4 for ammonia synthesis and CO2 photoconversion, through TRL 6-7 for hydrogen generation, up to TRL 9 for pollutants degradation.

Neutrons due to their penetrability, non-perturbative nature, isotopic and low-Z elements sensitivity are perfect scattering tool to study variety of systems including interfaces in different environments.
X-ray Free Electron Lasers (XFELs) are among the world's largest ongoing scientific endeavors. They provide intense, ultrashort pulses of coherent X-ray radiation, creating groundbreaking research opportunities [1]. XFEL experiments significantly advance our understanding across various fields, including medicine, pharmacology, chemistry, materials science, nanotechnology, energy, and electronics.
The instrumented indentation technique is a widely adopted method for assessing mechanical properties such as hardness, elastic modulus, and yield strength. Its ability to continuously measure penetration depth and applied force makes it particularly valuable for in-situ mechanical testing, especially at the nanoscale, enabling multi-purpose evaluations. However, challenges persist in accurately determining...
KAERI conducted tensile tests on Zircaloy-4 cladding and Cr-coated cladding at room temperature, 350°C, and 600°C. Two types of tensile tests were performed: the ring tensile test and the axial tensile test. This presentation provides...
Small modular reactors (SMRs), with capacities ranging from 30 to 300 MWe per unit, offer a scalable and compact alternative to traditional large-scale nuclear plants. They provide a promising solution to meet the growing energy demands driven by technology sectors like AI and data centers. These advanced reactors utilize molten salt as both fuel and coolant, exposing structural materials to the combined effects of high-temperature corrosion and intense irradiation from neutron fluxes. Understanding both...
The use of composite materials is constantly evolving, requiring further development and optimization of the mechanical properties of these materials. A number of strategies have been used in the past, choosing different types of fibers, resins and innovative geometric orientations for these fiber-reinforced plastics. Today's discussion will focus on polymer resins and their behavior during dynamic deformation. It is known that the mechanical properties of polymeric materials show...
Technological advancements in resolution, elemental analysis, and sample preparation have established transmission electron microscopy (TEM) as an indispensable tool for studying the structure and composition of a wide range of materials. When combined with modern, specialized in-situ systems, TEM can effectively function as a real-time nanoscale laboratory, enabling direct observation of processes such as growth, degradation, and particle interactions with resolutions down to a few nanometers. This presentation will...
Nuclear fusion and generation-IV fission reactor designs aim for operating temperatures in the range 500°C–1000°C. To optimise neutron efficiency, materials with low neutron cross section are sought for the fuel clad, or tritium breeding module. However, conventional zirconium alloys are precluded due to limited oxidation and creep performance at temperatures >400°C. Two approaches have been explored to meet...
On 3.02.2025, NCBJ's NOMATEN Centre of Excellence hosted experts from Bechtel Poland, a leader in engineering and construction. The study visit discussed opportunities for collaboration in research, testing, certification and qualification of materials used in PWR technology.
As the investigation of the materials' nanoindentation behavior is a nondestructive and powerful tool in the field of micromechanics, it is of no surprise that it has been attracting more attention from both researchers and engineers. Nanoindentation is a very versatile technique and in recent years it has been...
