Nanobubbles explain the large slip observed on lubricant-infused surfaces

Nature Communications, 2022
Why are lubricant-infused surfaces so effective at reducing drag in microfluidic flow? Here, authors reveal that infused nanostructured Teflon wrinkles induce large interfacial slip due to the spontaneous nucleation of surface nanobubbles, a mechanism ...

Reprogramming tumor immune microenvironment by ultrasound‐responsive nanoplatforms for enhanced cancer immunotherapy

BMEMat, EarlyView.
Ultrasound‐responsive nanoplatforms reprogram the tumor immune microenvironment by targeting tumor cells, immune cells, and non‐immune stromal cells to enhance the efficacy of cancer immunotherapy. Abstract Cancer immunotherapy represents a significant advancement in cancer treatment by enhancing the specific recognition and elimination of cancer cells.

Mechanical Stability of Surface Nanobubbles [PDF]

, 2019
Bubble cavitation is important in technologies such as noninvasive cancer treatment and diagnosis, surface cleaning, and waste-water treatment. The cavitation threshold is the critical external tensile pressure that induces unstable growth of the bubble.

Recent Strategies Toward Durable and Ion‐Tolerant Transition Metal‐Based Electrocatalysts in Seawater Electrolysis

Carbon Energy, EarlyView.
Recent strategies address these challenges through ion‐specific regulation, encompassing chloride‐tolerant and chloride‐regulating anodes together with cathode designs that suppress OH− accumulation and Mg2+/Ca2+ coupling. This ion‐management‐oriented framework provides general guidelines for achieving stable, selective, and scalable seawater ...

Molecular dynamics simulations of the surface tension of oxygen-supersaturated water

AIP Advances, 2017
In this work, non-reactive molecular dynamic simulations were conducted to determine the surface tension of water as a function of the concentration of the dissolved gaseous molecules (O2), which would in turn help to predict the pressure inside the ...

Effects of surface roughness on the hydrophilic particles-air bubble attachment

Journal of Materials Research and Technology, 2022
Bubble-particle attachment is a key factor in various material processing such as wastewater treatment and flotation separation. Nanobubble's formation and its stability on hydrophobic surfaces with and without surfactants have been scientifically proven

Carbon‐Doped Amorphous Gallium Oxide Forms a Heterojunction With Water to Improve the Electrocatalytic Oxygen Evolution Reaction

Carbon Energy, EarlyView.
A dynamic catalyst–H2O heterojunction (CWH) forms on ACG during OER, with periodic bubble evolution modulating band bending and interfacial charge transfer. Electron–radical coupling drives the generation of •OH/•O2− species, converting Ga2O3 into GaOOH, whereas surface CO32− from C doping stabilizes the interface, suppressing catalyst dissolution and ...

Stable bulk nanobubbles can be regarded as gaseous analogues of microemulsions [PDF]

, 2022
In our previous work [Phys. Chem. Chem. Phys. 2022, 24, 9685], we show with molecular dynamics simulations that bulk nanobubbles can be stabilized by forming a compressed amphiphile monolayer at bubble interfaces.
