Catalytic synergy between Pd nanoclusters and Ligand-functionalized layered silicates for improved formic acid dehydrogenation
(American Chemical Society (ACS), 2024-11-18)
Article
Restricted access - publisher's policyThe synthesis and stabilization of Pd nanoclusters on a support, as well as simultaneously achieving optimal catalytic activity, remain challenging tasks. Functionalizing the support surface with specific ligands offers a ... -
Numerical analysis of laminar velocity-forced premixed slit flames using modal decomposition techniques
(Elsevier, 2024-11)
Article
Restricted access - publisher's policyThe relation between Proper Orthogonal Decomposition (POD), Dynamic Mode Decomposition (DMD) and Flame Transfer Functions (FTF) is explored to gain further insight into the dynamics of two-dimensional laminar slit flames ... -
Irregular self-similar configurations of shock-wave impingement on shear layers
(2019-08-10)
Article
Open AccessAn oblique shock impinging on a shear layer that separates two uniform supersonic streams, of Mach numbers M1 and M2, at an incident angle si can produce regular and irregular interactions with the interface. The region ... -
Co-designing ab initio electronic structure methods on a RISC-V vector architecture [version 3; peer review: 4 approved, 1 approved with reservations]
(2024-11-14)
Article
Open AccessAb initio electronic structure applications are among the most widely used in High-Performance Computing (HPC), and the eigenvalue problem is often their main computational bottleneck. This article presents our initial ... -
Active flow control for drag reduction through multi-agent reinforcement learning on a turbulent cylinder at ReD=3900
(Springer, 2025)
Article
Open AccessThis study presents novel drag reduction active-fow-control (AFC) strategies for a threedimensional cylinder immersed in a fow at a Reynolds number based on freestream velocity and cylinder diameter of ReD = 3900. The ... -
Data-driven modeling of resolved and filtered thermo-diffusively unstable hydrogen–air flames
(Elsevier, 2024)
Article
Open AccessHydrogen premixed flames, under technically relevant conditions, are affected by intrinsic instabilities due to hydrodynamic and thermodiffusive effects, which are not taken into account by traditional turbulent combustion ... -
Deep reinforcement learning for active flow control in a turbulent separation bubble
(Nature Research, 2025)
Article
Open AccessThe control efficacy of deep reinforcement learning (DRL) compared with classical periodic forcing is numerically assessed for a turbulent separation bubble (TSB). We show that a control strategy learned on a coarse grid ... -
Occurrence of Gravitational Collapse in the Accreting Neutron Stars of Binary-driven Hypernovae
(IOP Publishing, 2024)
Article
Open AccessThe binary-driven hypernova (BdHN) model proposes long gamma-ray bursts (GRBs) originate in binaries composed of a carbon–oxygen (CO) star and a neutron star (NS) companion. The CO core collapse generates a newborn NS and ... -
A porohyperelastic scheme targeted at High-Performance Computing frameworks for the simulation of the intervertebral disc
(Elsevier, 2024)
Article
Open AccessBackground and Objective: The finite element method is widely used for studying the intervertebral disc at the organ level due to its ability to model complex geometries. An indispensable requirement for proper modelling ... -
Observation of magnetic islands in tokamak plasmas during the suppression of edge-localized modes
(2024)
Article
Open AccessIn tokamaks, a leading platform for fusion energy, periodic filamentary plasma eruptions known as edge-localized modes occur in plasmas with high-energy confinement and steep pressure profiles at the plasma edge. These ... -
A pseudo-spectral time-domain method for ultrasound wave propagation in soft biological tissue
(Elsevier, 2025-01-15)
Article
Open AccessWe introduce a Pseudo-Spectral Time-Domain (PSTD) method to simulate acoustic wave propagation in soft biological tissues, incorporating frequency-dependent power-law absorption and dispersion. A comprehensive Von-Neumann ... -
Performance Assessment of an Electrostatic Filter-Diverter Stent Cerebrovascular Protection Device: Evaluation of a Range of Potential Electrostatic Fields Focusing on Small Particles
(MDPI, 2024)
Article
Open AccessSilent Brain Infarction (SBI) is increasingly recognized in patients with cardiac conditions, particularly Atrial Fibrillation (AF) in elderly patients and those undergoing Transcatheter Aortic Valve Implantation (TAVI). ...
