A Physically Based Model for Non‐Point Source Pollutant Wash‐Off Process Over Impervious Surfaces

Water Resources Research, Volume 61, Issue 6, June 2025.
Abstract Physically based urban wash‐off modeling presents a promising approach for investigating the dynamics of road‐deposited sediments (RDS) and the associated pollutants during rainfall events. This paper proposes a novel physically based model to predict urban wash‐off process over impervious surfaces, where raindrop‐induced detachment, flow ...

Tailoring the Electrocatalytic Activity and Corrosion Resistance of CoCrFeNi and MnCrFeNi Thin Films by Anodization

Advanced Sustainable Systems, Volume 9, Issue 3, March 2025.
This work presents CoCrFeNi and MnCrFeNi thin films, synthesized by physical vapor deposition as bifunctional oxygen electrocatalysts that are corrosion‐resistant in alkaline conditions. After a detailed study of the film structure, the films are tested for oxygen catalysis and are active toward both oxygen evolution reaction (OER) and oxygen reduction

Tribological behavior of hydrogenated W-C/a-C:H coatings deposited by three different sputtering techniques

Cerâmica
The evolution of structure, mechanical properties and friction behavior of DC magnetron sputtered (DCMS), high power impulse magnetron sputtered (HiPIMS) and high target utilization sputtered (HiTUS) W-C:H coatings was investigated as a function of the ...

Bipolar HiPIMS kick‐pulse for high hardness in high‐entropy boride thin films

Journal of the American Ceramic Society, Volume 108, Issue 3, March 2025.
Abstract We report a microhardness indentation study for multicomponent refractory metal boride thin films that belong to the family of high‐entropy ceramics exhibiting superior hardness and high temperature properties. We focus on the nominally equimolar composition (Ti0.2Zr0.2Hf0.2Nb0.2Ta0.2)B2, which we refer to as HEB3, on c‐plane sapphire ...

Epitaxial growth of Cu(001) thin films onto Si(001) using a single-step HiPIMS process

Scientific Reports, 2017
We report on a new route to grow epitaxial copper (Cu) ultra-thin films (up to 150 nm thick) at ambient temperature on Si(001) wafers covered with native oxide without any prior chemical etching or plasma cleaning of the substrate.

Modelling of target effects in reactive HIPIMS

IOP Conference Series: Materials Science and Engineering, 2012
In reactive High Power Impulse Magnetron Sputtering (HIPIMS) of oxides, target effects such as reduced surface oxidation during pulse off time, increased implantation of reactive gas due to the higher discharge voltage as compared to normal DC sputtering, and enhanced target cleaning during on time are considered to be responsible for the differences ...

Chromium Coatings Applied to Zr Alloy Claddings by Cathodic Arc Ion Plating: Effect of Nitrogen Inclusion on Limiting Columnar Defects

Advanced Engineering Materials, Volume 26, Issue 20, October 2024.
The nitrogen incorporation effectively mitigates columnar defects in chromium‐based coatings on the Zr alloy claddings. The important significance of chromium‐based coatings is that they are suitable material candidates for accident‐tolerant fuel cladding of nuclear fuel rods.

Direct metallization of polymers: The HiPIMS effect on early thin film growth

Nano Trends
The metallization of polymers is essential for developing flexible electronics, yet precise control over metal film growth remains challenging. This study demonstrates the effect of high-power impulse magnetron sputtering (HiPIMS) markedly influencing ...

Hierarchical Metal‐Organic Network‐Forming Glasses toward Applications

Advanced Functional Materials, Volume 34, Issue 43, October 22, 2024.
Macro‐scale structurization and properties of metal‐organic framework glasses are correlated with medium‐range order of networks and local coordination geometries. The hierarchical MOF glasses in synthesis, shape adaptation, and structure‐property relationship are discussed for future industrial applications.
