Summary: The study demonstrates that using carbon dioxide nanobubbles can significantly improve the efficiency of CO2 gas transfer and buffering capacity compared to traditional bubbles. Furthermore, the beta values of nanobubbles are significantly higher than traditional bubbles, providing a significant source of CO2 availability by using the nanobubble method.

Summary: This study investigates the stabilization mechanism of bulk nanobubbles using molecular dynamics methods. The results show that the gas inside nanobubbles has ultrahigh density, there is a double-layer surface charge on the bubble, and the interaction between gas and water molecules weakens the interfacial hydrogen bond, which contributes to bubble stabilization.

Summary: The addition of salt significantly alters the stratification drainage process in micellar foam films formulated with ionic surfactants, leading to smaller step sizes and fewer steps in the thinning of the films. The long-range correlations between micelles are weakened, resulting in a rich nanoscopic topography and smaller intermicellar distances.

Summary: The temperature of the liquid has a significant impact on the generation and concentration of nanobubbles. Higher temperatures result in a higher concentration of negatively charged nanobubbles, while lower temperatures lead to the formation of larger bubbles and a decreased concentration of nanobubbles.

Summary: This article uses reactive molecular dynamics simulation technique to study the degradation mechanism of pollutants caused by shock-induced nanobubble collapse. The study finds that the collapsing nanobubble can focus mechanical energy through the converging motion of liquid, forming a high-speed jet with high energy density. Additionally, the mechanical nature of long-chain pollutant degradation and the mechanism of free radical generation are unveiled.

Summary: As predicted by classical macroscopic theory, the lifetime of nanoscale gas bubbles is extremely short but stable bulk nanobubbles have been experimentally detected. The stability of bulk nanobubbles depends on the surrounding liquid environment. By considering gas diffusion near the bulk nanobubble at different locations in a container, we introduce a gas transport parameter into the diffusion equation and compute the lifetime of single bulk nanobubbles using the MacLeod-Sugden relationship. Our findings suggest that the lifetime of a single nanobubble depends on its inner density and gas transport length.

Summary: Serum proteins form a protein corona around injected nanoparticles (NPs), with apolipoproteins being prominent components. Apolipoproteins may control NP distribution based on their affinity for NPs. It is important to understand the kinetics of apolipoprotein-NP affinity and how it affects NP biodistribution.

Summary: In this study, molecular dynamics simulations were used to investigate the growth of helium nanobubbles with different sizes and helium to vacancy ratios in copper. Various types of defects, including stacking fault octahedron, dislocation network, punched-out dislocation loop, and stacking fault tetrahedron, were found to nucleate around the nanobubbles. The mechanisms of formation and punching-out of the dislocation loops were also revealed. Additionally, an equation of state was proposed to predict the pressure of the nanobubbles inside copper based on the input parameters of bubble size, He/V ratio, and temperature.

Summary: The researchers successfully created 138 stable magnetic monopoles on a ferromagnetic meta-lattice and used soft X-ray vector ptycho-tomography to determine their magnetization vector and emergent magnetic field. The study found that the distances between monopole-anti-monopole pairs, monopole-monopole pairs, and anti-monopole-anti-monopole pairs were 18.3 +/- 1.6 nm, 36.1 +/- 2.4 nm, and 43.1 +/- 2.0 nm, respectively. This work demonstrates the potential of ferromagnetic meta-lattices as a platform for studying the interactions and dynamics of magnetic monopoles, and the broad application of soft X-ray vector ptycho-tomography for quantitatively imaging 3D vector fields in magnetic and anisotropic materials at the nanoscale.
