Hace 5 días · By leveraging the mutual attraction between metal ions, organic ligands, and MXene surface functional groups, MXene surfaces are efficiently functionalized through palladium coordination complexes. Subsequent ligand-induced growth facilitated the uniform nucleation of ultrafine metal nanoparticles, resulting in densely anchored nanoparticles of ...
Hace 4 días · Silanol groups react with hydroxyl groups on the surface of SiO 2-NPs to form covalent bonds, resulting in VTES being grafted onto the surface of SiO 2-NPs. Afterwards, DMPA (a compound containing acrylic functional groups) that reacts with silane coupling agents on the surface of SiO 2-NPs under ultraviolet light.
Hace 1 día · Scientists discovered that reducing GO membranes with ultraviolet (UV) light alters the oxygen functional groups on the GO surface. This modification results in a different, chromatography-like separation mechanism that is selective for charge rather than size. ... is essential to meeting the increasing demands for clean energy technologies and ...

Hace 4 días · The corresponding variation in energy and mean squared displacement (MSD) with the simulation process is presented in Fig. 3.The vdW energy is larger than electrostatic energy, which indicates the dominant position of vdW energy in steady state for Cu–Ag and Cu–Ag/surfactant systems, as shown in Fig. 3a, b. Meanwhile, the total energy of the system decreased first (within 100 ps) and then ...
Hace 5 días · Poor coal wettability limits the effectiveness of water injection in coal seams. Nanofluids and surfactants can improve the coal wettability. In this paper, the impact of four types of composite fluids containing surfactants and SiO2 nanoparticles on coal wettability was investigated. By analyzing the variation in contact angle and moisture content as well as functional groups before and after ...
Hace 4 días · Lithium metal is considered as one of the most promising anode material candidates for high-energy-density batteries. However, the solid electrolyte interface (SEI) of the lithium metal surface is susceptible to corrosion by hydrofluoric acid (HF) and H 2 O, which hinders the practical application of lithium metal. In this work, a functional composite polymer electrolyte (FCPE) containing Si ...
