Electrospray is a widely recognized physical process and has various applications, such as in electrospinning, space propulsion, mass spectrometry (MS). Particularly, electrospray emitters are integral to the exceptional performance of ionization (ESI-MS). This study introduced novel method for fabricating using two-photon direct laser writing, resulting printing nanosprayer arrays directly onto capillary tips. Utilizing acrylic polyhedral oligomeric silsesquioxane photoresist, multinozzle sprayer with micrometer scale channels was designed printed on that compatible both frontend liquid chromatography typical MS inlets. The 3D-printed sprayers demonstrated resistance organic corrosion high temperatures. For arrays, an increase total current achieved by augmenting number electrosprays, while maintaining constant flow rate voltage. Notably, eight-nozzle exhibited 2.7-fold enhancement sensitivity compared single-nozzle sprayers. approach offers versatile high-sensitivity nanoelectrospray solution ESI-MS.

Fiber-integrated micro/nanostructures play a crucial role in modern industry, mainly owing to their compact size, high sensitivity, and resistance electromagnetic interference. However, the three-dimensional manufacturing of fiber-tip functional structures beyond organic polymers remains challenging. It is essential construct fiber-integrated inorganic silica with designed nanostructures for microsystem applications. Here, we develop strategy 3D nanolithography from hybrid organic–inorganic materials by ultrafast laser-induced multiphoton absorption. Without nanoparticles polymer additives, acrylate-functionalized precursors can be locally cross-linked through nonlinear effect. Followed annealing at low temperature, as-printed are transformed high-quality sub-100 nm resolution. Silica microcantilever probes microtoroid resonators directly integrated onto optical fiber, showing strong thermal stability quality factors. This work provides promising fabricating desired micro/nanostructures, which helpful development device

Hierarchical structures are abundant in nature, such as the superhydrophobic surfaces of lotus leaves and structural coloration butterfly wings. They consist ordered features across multiple size scales, their advantageous properties have attracted enormous interest wide-ranging fields including energy storage, nanofluidics, nanophotonics. Femtosecond lasers, which capable inducing various material modifications, shown promise for manufacturing tailored hierarchical structures. However, existing methods, multiphoton lithography three-dimensional (3D) printing using nanoparticle-filled inks, typically involve polymers suffer from high process complexity. Here, we demonstrate 3D inorganic silicon-rich glass featuring self-forming nanogratings. This approach takes advantage our finding that femtosecond laser pulses can induce simultaneous cross-linking self-formation nanogratings hydrogen silsesquioxane. The combines patterning capability efficient generation periodic by We 3D-printed micro-supercapacitors with large surface areas a areal capacitance 1 mF/cm2 at an ultrahigh scan rate 50 V/s, thereby demonstrating utility device applications emerging storage.

Multicomponent oxide systems have many applications in different fields such as optics and medicine. In this work, we developed new hybrid photoresists based on a combination of an organic acrylate resin inorganic sol, suitable for 3D printing via two-photon polymerization (2PP). The sol contained precursors binary SiO2-CaO or ternary SiO2-CaO-P2O5 system. Complex microstructures were printed using these 2PP. obtained materials characterized thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) techniques. Our results revealed that the produced able to endure sintering at 700 °C without collapsing, leading scaffolds with 235 355 nm resolution pore size, respectively. According TGA analysis, there was no significant mass loss beyond 600 °C. After 500 °C, FTIR spectra showed disappearance characteristic bands associated phase, presence carbonate groups. SEM images morphologies agglomerated nanoparticles mean sizes about 20 60 systems, findings open way towards precise control bioglass scaffold fabrication tremendous design flexibility.
