Here, a highly dispersed Ni-doped MnO<sub>x</sub> catalyst (Ni<sub>0.1</sub>Mn<sub>0.9</sub>O<sub>x</sub>) was constructed and applied for selective catalytic reduction (SCR) of nitrogen oxides (NO<sub>x</sub>). The long-term stability of Ni<sub>0.1</sub>Mn<sub>0.9</sub>O<sub>x</sub> is up to 80% (180 °C) after 18 h under SO<sub>2</sub> and H<sub>2</sub>O conditions. This is due to the fact that the highly dispersed Ni atoms enhance the redox and surface acidity of MnO<sub>x</sub>, and modulate the electronic structure of the active Mn sites. The denitrification reaction on Ni<sub>0.1</sub>Mn<sub>0.9</sub>O<sub>x</sub> mainly follows the Eley-Rideal mechanism. The anti-poisoning mechanism is that the introduction of Ni weakens the electron transfer between the Mn site and SO<sub>2</sub>, thereby inhibiting the adsorption of SO<sub>2</sub>. In particular, the H<sub>2</sub>O adsorbed on the Ni sites is decomposed to replenish the depleted Brønsted acid sites, which facilitates the adsorption of NH<sub>3</sub>. However, an excess of H<sub>2</sub>O can have an inhibitory effect. In addition, the mesoporous structure may increase the mass transfer rate and reduce the accumulation of harmful substances.

Here, we investigate the tunability of hybrid vesicle interaction with three distinct cell lines through modulating non-specific interactions. We formulate vesicles composed of three different constituents, the zwitterionic lipid 1-palmitoyl-2-oleoyl-<em>glycero</em>-3-phosphocholine (POPC), the cationic lipid 1,2-dioleoyl-3-trimethylammonium-propane (DOTAP) and the amphiphilic diblock copolymer Poly(1,2-butadiene)-<em>b</em>-poly(ethylene oxide) (PBD<sub>22</sub>-PEO<sub>14</sub>). This enables the tunability of cell interactions through electrostatic attraction to anionic cellular membranes and steric repulsion from the polymeric PEO brush layer. We establish a microfluidic flow protocol to enhance the reproducibility of vesicle-cell interactions by controlling the hydrodynamic stresses during incubation and washing steps.

The superhydrophobicity of a series of materials including metal hydroxides, oxides, sulfides and chlorides, metals, and even hydrophilic organics, can be achieved by prefabricating their topographic textures combined with elemental sulfur surface modification.
