The innovative solutions for the use of flexibility in the power system
The increasing share of renewable distributed energy resources (DERs) in the power system is becoming a key for the decarbonization of the European energy sector and thus achieving the EU's energy and climate change policy objectives. The variability and uncertainty of the DERs generation present significant risks and challenges related to the stability and reliability of the entire interconnected European power system, as well as national and even small local networks while opening new opportunities for the development of new energy concepts and solutions.

Shocking in the field of pressure metrology
Accurate measurements of time-varying pressure are important to many industrial sectors. The most stringent requirements for accurate high-frequency pressure measurements come from the automotive, aerospace and ballistics industries, where pressure with frequencies up to few hundred kHz must be accurately measured. To provide dynamic calibrations of pressure meters in the required frequency range and therefore enable accurate measurements in the most demanding industries, many national metrology institutes worldwide are developing a primary dynamic measurement standard for pressure based on the shock tube. In the shock tube, the calibrated pressure meter can be excited by an almost ideal pressure step change generated by the reflection of the shock wave from the end wall of the shock tube. Such an extremely rapid reflection of the shock wave, in addition to generating the high-frequency pressure, inevitably also excites unwanted mechanical vibrations, which can produce spurious output signals of the pressure meter being calibrated.

Inductive response of phase separating battery materials
Understanding the processes in batteries is crucial for their proper design, control, management and analysis of the state of charge, health and safety. Physical sensors are a very important support for the advanced development and operation of batteries, and their combination with virtual models enables the exploitation of multiplicative effects, as mechanistically based models reveal a deeper insight into the phenomenology of the processes and enable their in-depth understanding.

SIMBA innovation in the fight against superbacteria
Innovation offers faster and cheaper solution in finding new active substances in the fight against superbacteria
The growing phenomenon of superbacteria, as we call bacteria that are resistant to multiple antibiotics, is a global health problem. The problem is exacerbated by the merging of bacteria in biofilms, which offers them protection and survival in very harsh conditions and facilitates the transmission of resistance. For this very reason the global development of new antibiotics is focused on their effects on other properties of the bacteria, such as attaching bacteria to the surface, movement or interaction between bacteria, and not just on survival. The new orientation of development urgently requires a new methodology. -
New method for structural health monitoring and failure
Lightweight structures such as wind turbines and aircraft are exposed to high dynamic loads during operation. Due to these operating conditions and their low mass, they vibrate. This is comparable to musical instruments, which produce sounds due to induced vibrations.
