The characterization of the oxide islands on the surface of the spatter contributes to a fundamental understanding of the formation and oxidation of spatter in laser powder bed fusion (LPBF). In the present study, the surface and cross-section characteristics of spatters with oxide islands are investigated using high resolution scanning electron mi...

The hot filament chemical vapor deposition (HFCVD) process is used to synthesize diamond crystals on cemented carbide (WC–Co) SPUN inserts. Diamond (Dia.), carbon (GC-glassy spherical form), iridium (Ir), molybdenum (Mo), palladium (Pd), platinum (Pt), tungsten (W), and tantalum (Ta) powders were used as seeding materials for crystal growth. Scanni...

The detection of changes in surface texture characteristics is an important issue in manufacturing, contact mechanics, control of interactions between surfaces, machine failure analysis, and others. These changes can be detected early on when surface texture is quantified locally at each point. To this end, a new method called local directional fra...

Current trends in scientific studies focus on the development of smartphone-based biosensors via green nanoparticle for clinical diagnosis, food, and environmental monitoring. In this study, we developed a novel portable smartphone-based biosensor via green dendrimer-coated matcha extract/silver nanoparticles (ME-Ag NPs) enriched with polyphenol fo...
Protein adsorption has a central role in the outcome of implants. However, there is no consensus about the impact of the different surface properties on the material-protein interactions. Here, the adsorption of albumin and fibronectin in near-physiological concentration is investigated on three differently treated titanium-based surfaces and compa...
Due to fossil fuels depletion and environmental pollution, clean and sustainable energy technologies, e.g. fuel cells and metal-air batteries, have attracted extensive attention. To push further the research on these electrochemical devices, low-cost, durable and efficient electrocatalysts alternative to platinum are required, to boost the oxygen r...

The applicability and capability of sorption techniques for comprehensive surface characterization of fibres including natural fibres, ligno-cellulosic fibres, cellulose nano-fibrils (CNFs), and cellulose nano-crystals (CNCs) are well established. This study provides comprehensive surface characterization of recycled and non-recycled cellulose-base...

Hastelloy-X is a nickel-based superalloy predominantly using in engine combustion zone parts of gas turbines. Micro-holes are drilling to the surface of these parts for air-cooling passageways to improve part-life by reducing thermal fatigue. Laser, micro-electric discharge machining (µEDM), and micro electrochemical machining (µECM) are the major ...
