Water and oxygen can move across the membrane of the alveoli in the lungs. How would their paths through the alveoli differ? How would the paths of water and oxygen moving through the alveoli cell membrane differ? How do the path...
The same trend was observed in H2O2, but the fraction of microrobots moving with 10° < θ < 80° slightly increased. Microrobots’ mobility was also examined under visible light irradiation, using blue light (Supplementary Fig. 8). No self-propulsion was observed in pure water; however,...
By facilitating a water/water phase separation (w/wPS), crowded biopolymers in cells form droplets that contribute to the spatial localization of biological components and their biochemical reactions. However, their influence on mechanical processes driven by protein motors has not been well studied. ...
2. Results and discussion 2.1 Femtosecond laser writing superhydrophobic microchannels Hierarchical microstructures should be built on the substrate with low surface energy to obtain underwater superaerophilicity [32-35]. PTFE sheet was adopted in this experime...
The differences between the two mechanisms are summarized in Table 2. Knowledge of the basic physics of HENGs is essential for understanding the different mechanisms. Table 2. Comparison of two mechanisms. Empty CellSteaming potentialIon gradient diffusion Energy source Atmospheric thermal energy Chemical...
Water moving through plants is considered meta-stable because at a certain point the water column breaks when tension becomes excessive — a phenomenon referred to as cavitation. After cavitation occurs, a gas bubble (i.e., embolism) can form and fill the conduit, effectively blocking wat...
We analyze here the role of the different driving forces moving water across epithelia and the biophysical properties of the water channels. We will also review the recently cloned epithelial members of the aquaporin family, including their expression and distribution in different tissues. 展开 关键词...
Active electrolocation organ of weakly electric fish act as a proximity detection system with high accuracy in recognizing object parameters such as size and shape. In contrast, some fish with passive electrolocation organ are able to detect objects at a
The types and concentrations of natural contaminates depend on the nature of the geological materials through which the groundwater flows and quality of the recharge water. Groundwater moving through sedimentary rocks and soils may pick up a wide range of compounds, such as magnesium, calcium, and...
The analysis was first done using a 30-day moving window for each day of year so as not to be subject to the arbitrary constraints of the calendar month. The 30-day moving window analysis did not differ considerably from a calendar-month analysis and therefore it was determined that ...
