“…It is connected with high thermodynamic stability of lattice oxygen [13]. But, it has been found [11,14] that mechanochemical treatment of catalysts results in a considerable increase in conversion and specific rate of hydrocarbon oxidation. It could be explained by increasing specific surface area [1][2][3][4], exposition of different crystallographic planes (structure sensitivity of MoO 3 in partial oxidation of propylene [15,16]), and different nonstoichiometric phase of MoO 3 , which provided after mechanochemical treatment.…”

“…Similarly, CoV‐oxides surface is also negatively charged (−15.08 mV) due to the adsorption of hydroxyl groups dissociated from water molecules. [ 46 ] Therefore, the electrostatic repulsive force between CoV‐oxides polyhedrons and MXene nanosheets makes the hybridization unachievable. In comparison, CTAB is positively charged owing to the presence of ammonium group and thus can be adsorbed electrostatically on CoV‐oxides surfaces.…”

Rechargeable batteries are deemed as green and efficient energy storage systems and have drawn great attention during past decades. Despite the commercial applications of lithium‐ion batteries, the ever‐increasing demands for higher energy storage capability driven by the rapid development of portable/wearable electronics remain unsatisfied due to the low theoretical capacity of the commonly used graphite anode. Herein, a material design strategy by synergizing the merits of conversion‐type Co2V2O7 and intercalation‐based Ti3C2Tx MXene for efficient lithium‐ion storage is reported. The Co2V2O7@MXene hollow polyhedrons are synthesized by ion exchange, surface modification, and the subsequent electrostatic assembly. Benefiting from the high conductivity and mechanical robustness of the MXene sheath, the high theoretical capacity of Co2V2O7, and the unique hollow structure, the optimized hybrids deliver a high output capacity of 949.7 mAh g−1 at 0.1 A g−1, excellent rate capacity with 431.4 mAh g−1 retained at 5.0 A g−1, as well as outstanding cycling stability.

“…A further purpose of zeta-potential measurements is to monitor changes of interfacial properties. Such monitoring may concern the coating of pigments (van Lent and Klinksiek 1997;Wilhelm and Stephan 2006), the mechanical activation of particle surfaces during grinding processes (Mende et al 2004;Skwarek et al 2011), or the fouling of walls and membranes (Park et al 2003). Sometimes the zeta-potential is employed as an indication for the interfacial properties (e.g.…”

Preparation and handling of colloidal suspension or even their characterisation is not possible without a basic understanding of the physical effects that prevail on the microscopic level. Some of these effects are directly related to the fineness of the particles because it coincides with a large specific surface area (which corresponds, e.g., to a high adsorption capacity), a considerably curvature of the particle surface (which i. a. promotes dissolution), a high number concentration (i.e. significant osmotic pressure and large collision frequencies), small interparticle distances (i.e. strong interactions between scattered waves), low particle mass (i.e. low weight and inertia), or with the fact that the wavelength of light is larger than particle size (i.e. weak optical scattering). A further effect of the small size of colloidal particles is that their diffusive motion is much faster than for micrometre particles. Moreover, the interactions between colloidal particles are decisive for the macroscopic behaviour of the whole suspension (e.g. with regard to rheology or coagulation). These interactions may be attractive and/or repulsive and depend on the chemical nature and the material properties of the particles. Most of all, they are affected by the interfacial properties which reflect the physico-chemical interaction between the particulate phase, the solvent, and the solutes (e.g. hydrophobicity, adsorption, surface charging).This chapter provides a brief introduction to the fundamentals in colloid science. It addresses the physico-chemical properties of single colloidal particles as well as the processes at the interface and the structure of the interfacial layer. It further examines the non-viscous interactions that occur among colloidal particles. For detailed explanation, the reader is referred to the textbooks of Adamson and Gast
