Abstract Janus particles that have regions with different properties (e.g., a metal and polymer) are of great interest for extensive technological aspects such as material environmental sciences, surface functional chemistry, drug delivery, biomedicals, micro/nanomotors. Numerous techniques, including masking, phase separation, self‐assembly, been presented in particle fabrication. Nonetheless, method precise fabrication is challenging necessary to control the accurately. Here,...
Abstract Conventional optical microscopes have a limit in resolution by diffraction of light. Here, we propose cylindrical microstructure-assisted nanoscale imaging to enhance the limit. The microstructures with diameters 3, 5, 7, and 9 μm were produced proton beam writing poly(methyl methacrylate) on nanopatterns commercial Blu-ray discs. Accordingly, disc imaged through using an Olympus LEXT OLS4000 confocal microscope determine microstructure performances for assisting nanoimaging....
Abstract Engineered microplastics are vital mimics of natural for application in many research areas aimed at solving environmental pollution. Here, we demonstrate the fabrication engineered using 1 MeV protons with a full penetration depth to effectively detach from substrate. The microplastic patterns this work were made an epoxy-based polymer (SU-8) spin-coated on silicon (Si) substrate by employing proton beam writing technique Shibaura Institute Technology. It was found that SU-8...
Photonic nanojet (PNJ) is an optical phenomenon that focuses incident light to a sub-wavelength beam waist/width and several wavelength long length by scattering with microstructure. Here, we report on the PNJs directly generated along axial axis of poly(methyl methacrylate) (PMMA) micro-cylinders 2, 4, 6, 8 μm diameters fabricated proton writing approach. Experimental results reveal PMMA were produced smooth surfaces, which are appropriate form PNJs. Accordingly, measured using in-house...
Proton beam writing (PBW) has been realized as a micro/nanofabrication technique that uses focused proton to directly pattern on the materials. At Shibaura Institute of Technology (SIT) in Japan, we have utilized PBW equipment with 1 MeV microbeam precisely create micro-patterns different shapes (circles, hexagons, pentagons, squares, and triangles) poly(methyl methacrylate) (PMMA) dielectric films spin-coated Cu electrodes. In this work, micro-patterned PMMA films/Cu electrodes were applied...
A triboelectric nanogenerator (TENG) has been emerged as a self-powered source that converts mechanical energy to electrical energy. Typically, surface modifications of dielectric materials with post micro/nanostructures have improved TENG output performance by increasing the contact areas. Herein, we propose embedded micro-pits in material produced proton beam writing at Shibaura Institute Technology for devices. Experimental results show enhancement voltages vertical contact-separation...
