Summary: The combination of bubble injection and superhydrophobic surfaces provides a solution to the challenges of air flow and depletion on the surface. By introducing bubbles over superhydrophobic surfaces with longitudinal grooves, the plastron can be replenished with a small amount of air even after the surface is fully wetted. The effective plastron thickness is related to surface light intensity, which serves as a criterion for successful replenishment.

Summary: The adhesion and subsequent icing of cold water on the insulation layers of dam coated with porous and hydrophilic concrete coating in a freezing environment might result in a severe ice pullout phenomenon. Although many superhydrophobic concrete (SC) coatings have been developed, their poor adhesive strength with the insulation layers has limited their application in protecting the insulation layers. Therefore, a novel superhydrophobic polymer concrete (SPC) coating was developed in this study by adding polyacrylate emulsion (PAE) and stone protector, as well as covering with nylon mesh. The SPC coating exhibited good superhydrophobicity and had a higher adhesive strength with the insulation layer compared to the SC coating, showing better performance in insulation layer protection. Additionally, the SPC coating also possessed excellent surface robustness, anti-icing capacity, and self-cleaning property, making it a promising candidate for insulation layer protection.

Summary: In this study, a series of bimetallic RhNi catalysts supported on MgAl2O4 were synthesized and used for low-temperature biogas dry reforming. The results showed that the RhNi catalyst achieved high conversion rates of CH4 and CO2 at low reaction temperature (600 degrees C) without carbon deposition. The enhanced coking resistance was attributed to the addition of Rh, which efficiently suppressed carbon formation, and the high surface areas of the MgAl2O4 support, which promoted CO2 adsorption and activation.

Summary: This study presents the introduction of Ti3C2Tx nanosheets with N, N-dimethylformamide as a dispersion aid in 5750 oil to obtain stable dispersions. Ball-on-disk wear testers demonstrate that MXenes have better wear reduction and antiwear performance. Relative to contrapositive 5750, the oil added Ti3C2Tx has a lower friction coefficient and wear rate. Particularly, the addition of Ti3C2Tx reduced the wear rate by 92% under 100 N, 25 celcius. Therefore, MXenes have great advantages and potential as a lubricating additive.

Summary: Heavy metal complexes in industrial wastewater pose a significant threat to public health. Conventional treatment usually involves a two-step process of advanced oxidation and precipitation. In this study, a one-stop technique using nano zero-valent iron (nZVI) was developed for simultaneous Cu(II)-EDTA decomplexation and copper capture. This technique was effective across a broad pH range and could remove Cu complexes from actual wastewater, meeting discharge standards. It provides a facile method for the destruction of Cu(II)-EDTA and capture of Cu, and offers insights into the decomplexation mechanism of heavy metal wastewater.

Summary: A CaO-assisted strategy was proposed to improve the catalytic combustion performance of chlorobenzene on SmMn2O5, solving the paradox of toxic byproduct formation and catalyst chlorine poisoning. The collaboration of CaO with SmMn2O5 decreased the T (90) by 142 and 125°C compared to unmodified and inert SiO2-composited SmMn2O5, respectively. The activated lattice oxygen (O-latt) enabled complete combustion of chlorobenzene at a lower temperature without generating toxic byproducts, and the switch of dechlorination site from SmMn2O5 to CaO avoided chlorine poisoning and provided prominent stability.

Summary: This study proposes a lattice Boltzmann model based on the heterogeneous nucleation and dendrite growth theories to predict frost formation and growth on surfaces with various wettabilities. Three lattice Boltzmann equations are used to calculate the velocity, humidity, and temperature distributions. The model is experimentally validated and applied to analyze frosting behaviors on plates and in microchannels, considering the effects of intrinsic contact angles and roughness on frost layer properties. This study facilitates a better understanding of frosting on the mesoscopic level.

Summary: Fluorescence Molecular Tomography (FMT) is an important technique for early tumor detection. However, existing methods fail in reconstructing multiple targets, hindering the practical application of FMT. In this paper, a multi-target reconstruction strategy based on Blind Source Separation (BSS) is proposed, which converts multiple target reconstructions into single-target reconstructions. The method has shown significant effectiveness and potential in preclinical FMT applications, with the ability to accurately locate and recover the morphology of multiple sources.

Summary: Based on first-principles calculations, we identified a series of magnetic adatoms with high structural stability and large magnetic anisotropy energy. The p-type systems, especially Pb and Bi, exhibit giant MAEs up to 157 meV and 313 meV, respectively. The large MAEs are mainly attributed to the orbital hybridization of degenerated p(x/y) orbitals near the Fermi levels, induced by ligand field and significant spin-orbit coupling interaction. Moreover, the robust magnetic anisotropy of individual Pb/Bi adatoms on the graphane surface is confirmed by comparing different magnetic configurations.
