Abstract Wetting is a surface phenomenon that commonly occurs in nature and has an enormous influence on human life. Slippery liquid‐infused porous surfaces have recently been developed to support the growing demand for anti‐fouling coatings. While short‐chain fluorinated compounds, used reduce energy of substrates, are banned due environmental toxicity, silane‐based compounds expensive barely scalable. In this sense, silicone‐based chemistry may match gap as real alternative. However,...
Abstract Single atom (SA) catalysis, over the last 10 years, has become a forefront in heterogeneous electrocatalysis, and most recently also photocatalysis. Most crucial when engineering SA catalyst/support system is creation of defined anchoring points on support surface to stabilize reactive sites. Here, so far unexplored but evidently very effective approach trap SAs broadly used photocatalyst platform introduced. In self‐organized anodic TiO 2 nanotubes, high degree stress incorporated...
Abstract In the present work, it is shown that anodic TiO 2 nanotubes (NTs) can be decorated with Pt, Pd, Rh, and Au single atoms (SAs) by a simple “dark deposition” approach. Such NTs surface trapped noble metal SAs provide high activity for photocatalytic H generation from pure water, i.e., in absence of sacrificial agent. However, metals also act as active centers undesired hydrogen back‐oxidation ( + O → ), leading to decrease overall production efficiency. Here reported use...
Anodic titanium dioxide (TiO2) nanostructures, i.e., obtained by electrochemical anodization, have excellent control over the nanoscale morphology and been extensively investigated in biomedical applications owing to their sub-100 nm topography range beneficial effects on biocompatibility cell interactions. Herein, we obtain TiO2 nanopores (NPs) nanotubes (NTs) with similar morphologies, namely, 15 diameter 500 length, investigate characteristics impact stem adhesion. We show that transition...
Peri-implantitis and peri-mucositis pose a severe threat to the success of dental implants. Current research focuses on development surfaces that inhibit biofilm formation while not inferring with tissue integration. This study compared adherence two oral bacterial species, Streptococcus sanguinis mutans nanostructured titanium surfaces.The samples included TiO2 nanotubes formed by anodization foil 100, 50 15nm diameter (NT15, NT50, NT100), nanoporous (15nm pore diameter) surface compact...
Titanium (Ti) is one of the most promising biomaterial for biomedical devices due to its high corrosion resistance and specific combination strength biocompatibility. dioxide (TiO2) nanostructures are obtained by electrochemical anodization Ti foils under self-organization condition; parameters such as time, voltage, temperature important electrolyte composition critical resulting morphology. Nanostructures grown in ethylene glycol (EG) based electrolytes we evaluated influence water...
Abstract: Titanium and titanium alloys are considered to be one of the most applicable materials in medical devices because their suitable properties, importantly high corrosion resistance specific combination strength with biocompatibility. In order improve biocompatibility surfaces, current report initially focuses on specifying topography dioxide (TiO2) nanotubes (NTs) by electrochemical anodization. The zeta potential (ζ-potential) NTs showed a negative value confirmed agreement between...
Here, we evaluate three different noble metal co-catalysts (Pd, Pt, and Au) that are present as single atoms (SAs) on the classic benchmark photocatalyst, TiO2. To trap surface, introduced controlled surface vacancies (Ti3+-Ov) anatase TiO2 nanosheets by a thermal reduction treatment. After anchoring identical loadings of Pd, Au, measure photocatalytic H2 generation rate compare it to nanoparticle nanosheets. While nanoparticles yield well-established hydrogen evolution reaction activity...
Abstract: Biomaterial implantation in a living tissue triggers the activation of macrophages inflammatory events, promoting transcription pro-inflammatory mediator genes. The initiation macrophage processes is mainly regulated by signaling proteins mitogen-activated protein kinase (MAPK) and nuclear factor kappa-light-chain-enhancer activated B cells (NF-κB) pathways. We have previously shown that titania nanotubes modified Ti surfaces (Ti/TiO 2 ) mitigate immune response, compared with flat...
