Probiotics are being developed as water additives to stimulate the immune system of fish, and improve quality by affecting microbial communities in fish culture environment. In present study, effect probiotics Bacillus cereus NY5 Alcaligenes faecalis Y311 on microbiota Nile tilapia tanks, themselves, were investigated. The (1.0 × 104 colony-forming units /mL) added separately experimental tanks every 7 days over a 3-month period. quality, environmental microbiota, enzyme activities...
Potassium dihydrogen phosphate (KDP, KH2PO4) crystal is an important kind of nonlinear optical because widespread use in high-intensity laser systems. A critical issue lasers the induced damage to dielectrics since fluence that components can stand sets upper limit operational Surface scratches on finished KDP surface were artificially generated and characterized with nano-indenter atomic force microscope (AFM), respectively. The varied depth, directions shapes. morphology different quite...
Three-dimensional printing enables the fabrication of silica glass optics with complex structures. However, shrinkage remains a significant obstacle to high-precision 3D optics. Here we 3D-printed Dammann gratings (DGs) low lateral (<4%) using two-photon polymerization (2PP) technique. The process consists two steps: patterning polymerizable slurry 515 nm femtosecond laser form desired structures and debinding/sintering into transparent dense glass. sintered exhibited distinct rates in...
A simple and efficient process for fabricating customized aspheric lenses is reported, in which a stereolithographic 3D printer combined with the meniscus equilibrium post-curing technique employed. Two kinds of UV-curable resins, DentaClear HEMA, were used printing our experiments. The printed lens featured low surface profile deviation ~74 μm showed satisfactory optical imaging resolution 50.80 lp/mm, i.e., 4.92 μm. roughness was measured to be around 2 nm AFM. improved as result...
Micro-flow smoothing of fused silica surface with CO2 lasers were numerically simulated.Two types laser intensity distribution, namely Gaussian and top-hat, modeled on various morphology.In the models, tension Marangoni effect taken into account.The results show that acts synergically whereas dominates resultant in our simulated conditions.Top-hat is conducive to glass.In addition, surfaces both periodic random topography can be smoothed.Under 585.69W/cm 2 power density, best roughness (RMS)...
The thermal deformation of silica glass reflectors employed in high-power laser systems has emerged as a critical issue, imposing limitations on the scalability lasers to achieve high average power and beam quality. Water-cooling is most effective commonly method for reducing deformation. However, it challenging create embedded microchannels water-cooling by conventional processing methods. In this study, we demonstrate novel fabricating microchannel combining slurry UV-curing with 3D...
