1. Findings from National Institute for Laser Plasma and Radiation Physics in Obesity, Fitness and Wellness Reported (Surface Properties and Antibacterial Characteristics of Polyurethane Modified By Corona Discharge for Food Processing Industry).

Subjects

Abstract

A recent study conducted by the National Institute for Laser Plasma and Radiation Physics in Magurele, Romania, explored the surface properties and antibacterial characteristics of polyurethane (PU) modified by corona discharge for the food processing industry. The researchers found that exposing PU substrates to corona discharge using air as a treatment gas resulted in changes in surface hydrophobicity and minimal changes in surface morphology. The hydrophilic surfaces developed a strong resistance to bacterial adherence within a few hours of incubation. This research provides valuable insights into improving the durability and safety of conveyor belts in the food processing industry. [Extracted from the article]

Abstract

We present an integrated study on the scalability and performance of particle-in-cell (PIC) code simulations on CPU and GPU architectures of high parallelization focused on target normal sheath acceleration (TNSA) and laser wakefield acceleration (LWFA) experiments. The developed models follow the experimental specifications of the high-power lasers systems hosted at the infrastructures of the Institute of Plasma Physics & Lasers of the Hellenic Mediterranean University in Crete, Greece and the Extreme Light Infrastructure - Nuclear Physics in Romania. The simulations are implemented on the High-Performance Computer for Advanced Research Information System of the Greek National Infrastructures for Research and Technology. Two representative experiments for TNSA and for LWFA are initially simulated by 2D models with the minimum computational resource demands and the results are used as a reference for the scalability and performance investigation. We further extend our study to 3D models aiming to reproduce the physics involved in both laser-plasma particle accelerators. A detailed analysis of the simulation results, accompanied with the computational demands, scalability and performance of the CPU and the GPU architectures, is provided. Our research findings highlight the key features and parameters of the physical and numerical models which drive simulations to converge to reliable results by means of physics, computational and runtime demands and shed light on their influence on the efficiency and performance of the PIC simulations.

3. New Chemicals and Chemistry Study Findings Have Been Reported by Investigators at National Institute for Laser Plasma and Radiation Physics (Titanium Surface Nanostructuring By Picosecond Laser Irradiation for Surface Improvement of Dental...).

Subjects
PLASMA physics, LASER plasmas, LASER beams, PLASMA radiation, TITANIUM
Abstract

A recent study conducted by researchers at the National Institute for Laser Plasma and Radiation Physics in Magurele, Romania, explores the use of high-repetition rate picosecond laser processing as a method for surface improvement of dental abutments made of titanium. The study found that laser nanostructuring of titanium surfaces can enhance the viability, proliferation, adhesion, and morphology of human mesenchymal stem cells (hMSCs) after 7 days of culture. The research suggests that this alternative approach could promote better cell growth and adhesion compared to traditional methods. The study has been peer-reviewed and published in the Journal of Laser Micro Nanoengineering. [Extracted from the article]

Abstract

A recent report discusses research conducted at the National Institute of Lasers Plasma and Radiation Physics in Magurele, Romania, on information and data encoding and encryption. The researchers used chaotic lasers with different external cavity geometries and applied the chaotic masking method to achieve secure data transmission. By optically coupling and synchronizing two semiconductor lasers, the researchers were able to encrypt and decrypt messages using radio frequency spectrum monitoring. The research findings suggest the robustness of the encryption method and the synchronization characteristics of the lasers. This research has been peer-reviewed and published in Romanian Reports In Physics. [Extracted from the article]

Abstract

Extreme Light Infrastructure (ELI) aims at establishing an international laser research infrastructure hosting the worldwide most advanced ultra-high power lasers and gamma beam system. The project was listed in the 2006 road-map of the European Strategy Forum on Research Infrastructure (ESFRI) and since 2013 it entered the implementation phase co-financed with EU Structural Funds. The project promotes a new concept of pan-European research infrastructure distributed in several European countries and operated as a user facility opened to the whole international scientific community. The infrastructure will be built on four pillars, three of them being presently in the implementation phase: (1) ELI Beamlines in Prague, Czech Republic, focused on the production of ultra intense and ultra short pulses of electrons, protons, and ions; (2) ELI Attosecond in Szeged, Hungary, dedicated to the investigation of electron dynamics in atoms, molecules, plasmas, and solids at the attosecond level; and (3) ELI–Nuclear Physics in Bucharest, Romania, dedicated to laser-based nuclear physics research.
