In-cylinder imaging diagnostics with highly efficient UV-transparent endoscopes
نویسندگان
چکیده
Laser-based in-cylinder diagnostics are well established in engine research. The requirement of large-scale optical accesses, however, makes the application expensive and time consuming. It furthermore limits the engine operation range to low loads and speeds. We introduce laser excitation and imaging optics with a minimal outer diameter of 10 mm (imaging optic) respectively 9 mm (excitation optics). The imaging optics allows the observation of a 30×30 mm 2

An endoscope with integrated transparent bioelectronics and theranostic nanoparticles for colon cancer treatment.
The gastrointestinal tract is a challenging anatomical target for diagnostic and therapeutic procedures for bleeding, polyps and cancerous growths. Advanced endoscopes that combine imaging and therapies within the gastrointestinal tract provide an advantage over stand-alone diagnostic or therapeutic devices. However, current multimodal endoscopes lack the spatial resolution necessary to detect ...
متن کاملWelding of silver nanowire networks via flash white light and UV-C irradiation for highly conductive and reliable transparent electrodes
In this work, silver nanowire inks with hydroxypropyl methylcellulose (HPMC) binders were coated on polyethylene terephthalate (PET) substrates and welded via flash white light and ultraviolet C (UV-C) irradiation to produce highly conductive transparent electrodes. The coated silver nanowire films were firmly welded and embedded into PET substrate successfully at room temperature and under amb...
متن کاملA method of fabricating highly transparent and conductive interpenetrated carbon nanotube-parylene networks.
We report a method of fabrication of free standing and ultra-thin carbon nanotube-parylene-C interpenetrating networks. The network is highly transparent, highly flexible, and more conductive than transparent nanotube/polymer composites. Scanning electron microscope imaging reveals that the interpenetrated networks are dense and pinhole free compared to bare nanotube networks. We found that par...
