Genetically encodable gas-filled particles, known as gas vesicles (GVs), have shown promise a biomolecular contrast agent for ultrasound imaging and the potential to be used cavitation nuclei therapy. In this study, we passive acoustic mapping techniques characterize GV-seeded cavitation, utilizing 0.5 1.6 MHz insonation over peak rarefactional pressures ranging from 100 2200 kPa. We found that GVs produce duration of first applied pulse, up at least 5000 cycles, but bubble activity...
To achieve efficient and sustainable NH3 production by electrochemical nitrogen reduction at room temperature, the catalyst must have high activity superior stability. Here, we prepared a series of two-dimensional BixSby alloy nanosheet materials with different atomic ratios improved coreduction method. Experiments density functional theory (DFT) calculations reveal following. (i) The uniformly distributed catalysts not only larger specific surface area, thereby promoting full exposure Bi...
In order to effectively prevent coal mine accidents, we selected the most serious type of accident in mines—gas explosions—as research object. Based on causation model (24Model), propose an action path and analysis steps accidents caused by different employees organization. A gas explosion was analyzed using 24Model proposed path, 12 unsafe actions, 3 states, 4 habitual behaviors, 10 safety management systems, cultures were obtained. Case results show that effect can help clearly identify...
Hydrate-based gas storage holds a huge potential to become promising technology in the future, provided that conditions are moderate enough. Tetrahydrofuran (THF), widely known promoter, is used this study understand its effect on hydrate phase equilibrium and cage occupancies thereafter. Here, we present fugacity-based thermodynamic model three-phase liquid-hydrate-vapor (L-H-V) equilibria of CH4 pure water (sI hydrate) 0.48–5.56 mol % THF solutions (sII hydrate). The uses vdW-P theory for...
The crucial factor of laser welding is the energy conversion. For a better understanding process, interaction process between beam and keyhole wall was investigated by observing evaporation during high-power fiber welding. results show that vapor, induced beam, discretely distributed on wall. A tiny 'hollow' zone observed at spot center-action region FKW. vapor center moved downward along front (FKW) with period about 0.3~0.75 ms, which indicates formation reminiscent periodical drilling...
Oxygen and Indocyanine Green (ICG) loaded microparticles (OI-MPs) were fabricated by a gas-driven coaxial flow focusing (CFF) process for dual-mode imaging sonodynamic therapy (SDT). The produced OI-MPs agent showed stable optical properties, superior depth in near infrared (NIR) fluorescence imaging, enhanced acoustic contrast after ultrasound mediation. We hypothesized that encapsulating ICG oxygen would enhance reactive species (ROS) production SDT. This hypothesis was validated cell-free...
Severe spattering is one of the common problems during fiber laser keyhole welding. In this study, correlation between spatter formation and laser-induced evaporation vapor on front wall (FKW) was studied by changing welding speed The spatters were mainly generated in behind mouth, diameters 50~100 μm at low speed, while particles 100~150 high speed. As increased, tilt angle FKW decreased gradually, main generation position shifted from mouth to mouth. velocity higher than that Further...
A capillary co-flow focusing process is developed to generate stimuli-responsive microbubbles (SRMs) that comprise perfluorocarbon (PFC) suspension of silver nanoparticles (SNPs) in a lipid shell. Upon continuous laser irradiation at around their surface plasmon resonance band, the SNPs effectively absorb electromagnetic energy, induce heat accumulation SRMs, trigger PFC vaporization, and eventually lead thermal expansion fragmentation SRMs. This optical droplet vaporization (ODV) further...
