At present, the widespread use of iron oxide nanoparticles, including for commercial purposes, requires strict preservation their phase composition during application. The choice nanoparticle modifier and modification conditions is decisive due to high sensitivity oxygen in case using real (O2, pH change, etc.). In this work, we studied change magnetite nanoparticles after with 3-aminopropyltri...

Improvements in durable lubrication together with minimized wear are essential for obtaining long-term, functioning metallic joint prostheses. To achieve this objective, CoCr surface was functionalized Graphene Oxide (GO) and characterized by FTIR XPS. alloy subjected to alkalinization order generate high hydroxyl content on the surface. XPS revealed reactive OH groups, enabling intermediate co...

All-inorganic CsPbI3 perovskite quantum dots (PeQDs) have sparked widespread research due to their excellent optoelectronic properties and facile synthesis. However, attaining highly stable against heat polar solvents still remains a challenge hinders any further practical application. Here, by exploiting (3-aminopropyl) triethoxysilane (APTES) as the sole silica (SiO2) precursor, we report one...

Self-assembled dielectric microlenses are used for focusing of the fluorescent signal emitted from a surface-based immunoassay, performed on silane micropatterns as assay substrates, to enhance the detection signal. In our model system, a fluorescent immunocomplex is formed on (3-aminopropyl)triethoxysilane (APTES) microstructures, and then carboxyl-functionalized melamine microparticles with t...

An inorganic-organic hybrid fluorescence chemosensor (DA/SBA-15) was prepared by covalent immobilization of a dansylamide derivative into the channels of mesoporous silica material SBA-15 via (3-aminopropyl)triethoxysilane (APTES) groups. The primary hexagonally ordered mesoporous structure of SBA-15 was preserved after the grafting procedure. Fluorescence characterization shows that the obtain...

Significant advancement has occurred in the detection methods of solution-based analytes. High-pressure liquid chromatography, gas and other systems used for analyses are quite expensive. Therefore, there is a need new visible Here, we demonstrate that 3-aminopropyl triethoxysilane (APTES) could impact stability, optical, morphology gold nanoparticles (AuNps) colloidal solution. These impacts c...

In this work, TEMPO cellulose nanofibril (TOCNF) laminates were fabricated using a layup method. Two different TOCNF layers tested, neat and with polyvinyl alcohol (PVA) strengthening aid four epoxy formulations as interlayers for the laminates. Flexural testing showed correlation between presence of stronger (TOCNFs + PVA) in laminate higher flexural strength, bending modulus, work failure. Di...
