In response to growing environmental concerns, there is a need for accurate and efficient methods to detect water pollutants. This research focuses on developing an advanced microchannel-based Surface-Enhanced Raman Spectroscopy (SERS) substrate. This innovative platform aims to identify various water contaminants, including pharmaceutical residues like diclofenac, caffeine, and carbamazepine....

A cost-effective, Co-free Fe-based medium entropy alloy (MEA), was developed to achieve an exceptional combination of strength and ductility at both room and cryogenic temperatures. The Co-free design is strategically motivated by the high cost, supply risk, and density associated with Co-containing alloys, making the present system more economically and industrially viable without...

Laser-produced plasmas (LPPs) are widely used as light sources for laser-induced breakdown spectroscopy (LIBS) and for nanoparticle generation. The optical emission properties of LPPs are strongly governed by early laser–plasma interaction dynamics. In this study, advanced laser beam shaping was employed to control plasma formation and emission during laser ablation of metallic and...

Transparent p–n junctions are essential for the next advancement in transparent electronics (displays, sensors, or solar cells). The challenges arise from the lack of high-quality p-type transparent conducting oxides. A promising candidate is CuCrO2, a wide-bandgap delafossite, which offers both p-type conductivity and strong transparency.
In this P4F project, pulsed laser deposition (PLD)...

Due to their size ranging from one nanometre to a few hundred nanometres, nanoparticles exhibit a high surface-to-volume ratio and specific light-matter interactions (plasmon effect) that benefit applications such as catalysis, optics, and medicine. Chemical synthesis methods dominate the market due to their strong reproducibility and tunable properties. However, these methods are highly...

To regulate reactive HiPIMS processes of vanadium oxides, plasma diagnostics based on the RF Sobolewski probe theory has been carried out. In addition to the typical approach of using a probe inserted into the chamber at the substrate side, a novel non-invasive approach using the target as an in-situ probe has also been developed. The RF Sobolewski probe method enables the measurements of ion...
