“…Fig. 19c shows a well-defined cluster of B4 nm with the hexagonal profile and rhombic internal contrast that are characteristic for a truncated 350 octahedron particle observed in the (011) zone axis. The HRTEM images allow defects to be found in the nanocrystalline material, as marked with an arrow in Fig.…”

Hallmarks of mechanochemistry: from nanoparticles to technology

The aim of this review article on recent developments of mechanochemistry (nowadays established as a part of chemistry) is to provide a comprehensive overview of advances achieved in the field of atomistic processes, phase transformations, simple and multicomponent nanosystems and peculiarities of mechanochemical reactions. Industrial aspects with successful penetration into fields like materials engineering, heterogeneous catalysis and extractive metallurgy are also reviewed. The hallmarks of mechanochemistry include influencing reactivity of solids by the presence of solid-state defects, interphases and relaxation phenomena, enabling processes to take place under non-equilibrium conditions, creating a well-crystallized core of nanoparticles with disordered near-surface shell regions and performing simple dry time-convenient one-step syntheses. Underlying these hallmarks are technological consequences like preparing new nanomaterials with the desired properties or producing these materials in a reproducible way with high yield and under simple and easy operating conditions. The last but not least hallmark is enabling work under environmentally friendly and essentially waste-free conditions (822 references).

“…is closer to that of CdS (2.4 eV) than the hexagonal wurtzite ZnS, 55 which has a band gap of 3.9 eV. Current conventional synthesis 56 routes for ZnS include chemical precipitation [5], electro-explosion 57 of wire [6], pulsed laser deposition at 600°C [4], ultrasonic spray 58 pyrolysis at 700°C with argon [7], and high-energy milling [8]. 59 Metal sulfide NPs have also been produced using endogenous 60 methods such as heavy metal tolerance and detoxification processes 61 such as reaction with hydrogen sulfide (H 2 S) [9].…”
