Special Issue Information

Dear Colleagues,

Mechanochemistry dealing with mechanochemical reactions that are induced by mechanical energy-milling has made significant progress in recent years. The identified hallmarks of this branch of chemistry include:

  • Influencing reactivity by creating interphases in composite and multi/phase systems, by defects in solids and by the existence of relaxation phenomena;
  • Creating well-crystallized cores of nanoparticles with disordered near-surface shell regions;
  • Performing simple, dry, time-convenient one-step syntheses;
  • Preparing nanomaterials, nanocomposites with properties set in advance;
  • Scaling up to industrial production; and
  • Feasibility of manufacturing under environmentally friendly and essentially waste-free conditions.

This Special Issue aims to collect scientific knowledge and examinations of all the “mechanochemists” conducting investigations in the field of Mechanochemistry and Nanotechnology covering all aspects from inorganic and organic mechanochemical synthesis, elucidation of the mechanism of the mechanochemical reactions, metal–organic frameworks, nano-structured semiconductors and advanced synthesis of nanomaterials for solar cells, thermoelectrics, energy, hydrogen storage, biological and environmental applications, crystal engineering, industrial application of mechanochemistry in nanotechnology, and development of new approaches and methodologies.

Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nanomaterials is an international peer-reviewed open access monthly journal published by MDPI.

Sustainable One-Step Solid-State Synthesis of Antibacterially Active Silver Nanoparticles Using Mechanochemistry
Nanomaterials 2020, 10(11), 2119; https://doi.org/10.3390/nano10112119 - 25 Oct 2020
Abstract
A combination of solid-state mechanochemical and green approaches for the synthesis of silver nanoparticles (AgNPs) is explored in this study. Thymus serpyllum L. (SER), Sambucus nigra L. (SAM) and Thymus vulgaris L. (TYM) plants were successfully applied to reduce AgNO3 to AgNPs, [...] Read more.
A combination of solid-state mechanochemical and green approaches for the synthesis of silver nanoparticles (AgNPs) is explored in this study. Thymus serpyllum L. (SER), Sambucus nigra L. (SAM) and Thymus vulgaris L. (TYM) plants were successfully applied to reduce AgNO3 to AgNPs, as confirmed by X-ray diffraction analysis, with SER being the best reducing agent, and TYM being the worst. The experiments were performed via a one-step planetary milling process, where various AgNO3:plant mass ratios (1:1, 1:10, 1:50 and 1:100) were investigated. Atomic absorption spectrometry indicated that the stability of the mechanochemically produced AgNPs increased markedly when a sufficiently large quantity of the reducing plant was used. Furthermore, when larger quantities of plant material were employed, the crystallite size of the AgNPs decreased. TEM analysis revealed that all AgNPs produced from both AgNO3:plant ratios 1:1 and 1:10 exhibit the bimodal size distribution with the larger fraction with size in tens of nm and the smaller one below 10 nm in size. The antibacterial activity of the produced AgNPs was observed only for AgNO3:plant ratio 1:1, with the AgNPs prepared using SER showing the greatest antibacterial properties. Full article

Comparative Study of Nanostructured CuSe Semiconductor Synthesized in a Planetary and Vibratory Mill

Copper(II) selenide, CuSe was prepared from Cu and Se powders in a stoichiometric ratio by a rapid, and convenient one-step mechanochemical synthesis, after 5 and 10 min of milling in a planetary, and an industrial vibratory, mill. The kinetics of the synthesis, and the structural, morphological, optical, and electrical properties of CuSe products prepared in the two types of mill were studied. Their crystal structure, physical properties, and morphology were characterized by X-ray diffraction, specific surface area measurements, particle size distribution, scanning, and transmission electron microscopy. The products crystallized in a hexagonal crystal structure. However, a small amount of orthorhombic phase was also identified. The scanning electron microscopy revealed that both products consist of agglomerated particles of irregular shape, forming clusters with a size ~50 μm. Transmission electron microscopy proved the nanocrystalline character of the CuSe particles. The optical properties were studied using UV–Vis and photoluminescence spectroscopy. The determined band gap energies of 1.6 and 1.8 eV for the planetary- and vibratory-milled product, respectively, were blue-shifted relative to the bulk CuSe. CuSe prepared in the vibratory mill had lower resistivity and higher conductivity, which corresponds to its larger crystallite size in comparison with CuSe prepared in the planetary mill.
