Special Issue Information

Dear Colleagues,

After our successful first edition of the Special Issue “Materials Containing Silicon, Its Inorganic Derivatives, Functional Silanes, and/or Organosilicon Polymers”, we have decided to create a 2nd edition to collect and publish state-of-the-art research in this field.

A semiconductive pure silicon is used as a basic electronic material for production of computer chips and other electronic devices. Many functional silanes of different chemical structures containing reactive groups, mostly bound to silicon atom, but also quite often attached to carbon atom are applied for modification of surface properties of different polymeric and inorganic materials, e.g., fillers.

Silicones (polysiloxanes), containing silicon and oxygen atoms in their main chains and organic substituents bound to silicon, are a large and most important group of various inorganic-organic (hybrid) compounds and materials. Mainly poly(dimethylsiloxanes) (PDMS) are used. Silicones are applied as oils, rubbers, and resins. They have many unusual features - they exhibit excellent chemical, physical, and electrical properties. Even an addition of  a very small amount of silicones  
leads to a crucial improvement of properties of modified materials. Silicones increase hydrophobicity and improve water resistance and thermal stability of many materials.

Other organosilicon polymers, and especially, polysilanes, polycarbosilanes, and polysilazanes, are raw materials for fabrication of polymer-derived high-tech ceramic materials. Silicon-based polymers and polymeric materials as well as reactive silane coupling agents (SCA) are used in many fields – from industry, through everyday life commodity goods and cosmetics, to medicine. Their universal properties decide that they are very useful and attractive materials and components in a very wide range of products.

A continuously growing interest in applications of reactive silanes, all kinds of silicones, chemically modified nanosilica, different composites, silicon photovoltaic cells, and silicon nanowires has been still observed in many different fields of science, the chemical technology, and especially in materials science.

Original contributions and reviews are welcome.

Silicon-based anodes are considered promising alternatives to graphite anodes owing to their high theoretical lithium-storage capacity and abundant reserves. However, silicon nanoparticle anodes are severely limited by large volume expansion, unstable interfacial chemistry, and poor electrical connectivity during repeated lithiation/delithiation. Herein, we develop a yolk–shell N-doped carbon network (NCN) strategy to construct Si@void@NCN composites. The optimized Si@void@NCN-1 achieves a balanced architecture between void buffering and carbon network integrity, delivering a high initial discharge capacity of 1245.5 mAh g−1 and an initial charge capacity of 735.8 mAh g−1. It also demonstrates stable long-term cycling performance, retaining a reversible capacity of 402.5 mAh g−1 after 500 cycles at 0.5 A g−1 with a capacity retention of 68.66%, and shows improved rate reversibility and electrode structural stability, with an electrode thickness increase of only 80.4% after rate cycling, much lower than that of densely carbon-coated Si@C. Kinetic analysis, post-cycling structural characterization, and in situ EIS further reveal that the yolk–shell void-buffering structure and the N-doped three-dimensional conductive network act synergistically to mitigate Si volume expansion, enhance structural stability, and facilitate electron/ion transport. This study emphasizes the importance of integrating buffering structures with Si/C composites, providing guidance for the rational design of advanced silicon-based electrode materials. Full article

Abstract
In this work, a multifunctional surface engineering strategy was developed to impart both flame-retardant and hydrophobic properties to cotton fabrics. In the first stage, cellulose fibers were modified with poly(methylvinyl)siloxane containing trimethoxysilyl groups, 2,4,6,8-tetramethyl-divinyl-bis(trimethoxysilylpropyltioethyl)cyclotetrasiloxane, or tetrakis(vinyldimethylsiloxy)tetrakis(trimethoxysilylpropyltioethyl)octasilsesquioxane (POSS). All modifiers contained alkoxysilyl groups capable [...] Read more.
In this work, a multifunctional surface engineering strategy was developed to impart both flame-retardant and hydrophobic properties to cotton fabrics. In the first stage, cellulose fibers were modified with poly(methylvinyl)siloxane containing trimethoxysilyl groups, 2,4,6,8-tetramethyl-divinyl-bis(trimethoxysilylpropyltioethyl)cyclotetrasiloxane, or tetrakis(vinyldimethylsiloxy)tetrakis(trimethoxysilylpropyltioethyl)octasilsesquioxane (POSS). All modifiers contained alkoxysilyl groups capable of forming covalent bonds with cellulose hydroxyl groups. The modification was performed using a dip-coating process followed by thermal curing. This procedure enabled the formation of Si-O-C linkages and the generation of a reactive organosilicon layer on the cotton surface. In the second step, O,O′-diethyl dithiophosphate was grafted directly onto the vinyl-functionalized fabrics via a thiol-ene click reaction. This process resulted in the formation of a phosphorus- and sulfur-containing protective layer anchored within the siloxane-based network. The obtained hybrid coatings were characterized using Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and SEM-EDS. These analyses confirmed the presence and uniform distribution of the modifiers on the fiber surface. Microscale combustion calorimetry demonstrated a substantial reduction in the heat release rate. Thermogravimetric analysis (TG/DTG) revealed increased char formation and altered thermal degradation pathways. The limiting oxygen index (LOI) increased for all modified fabrics, confirming enhanced flame resistance. Water contact angle measurements showed values above 130°, indicating effective hydrophobicity. As a result, multifunctional textile surfaces were obtained. In addition, the modified fabrics exhibited partial durability toward laundering and retained measurable flame-retardant and hydrophobic performance after repeated washing cycles. Full article

This work focuses on developing resistive switching (RS) devices using thermally annealed (TA) SiO2/Si multilayers (ML). Three SiO2/Si bilayers were deposited with an additional 10 nm SiO2 layer as a dielectric barrier layer on top of the ML. The SiO2 layers were 6 nm thick, while the thickness of the Si layers varied from 2, 4, and 6 nm, and were labeled as ML-62, ML-64, and ML-66, respectively. X-ray photoelectron spectroscopy analysis revealed well-defined ML structures before TA. However, after TA, samples ML-64 and ML-62 showed discontinuities due to diffusion between neighboring Si layers, increasing the dimensions of the Si-rich regions. In fact, the concentration of elemental Si (Si0) within the intermediate Si layer increases as the Si layer becomes thinner. Consequently, the size of Si-nanocrystals, created after TA, increases from 6 to 8.5 nm for ML-66 to ML-62, as confirmed by Raman and transmission electron microscopy analysis. The composition discontinuities and loss of the ML structure resulted in erratic electrical behavior, with an electroforming (EF) voltage as high as −14 V in sample ML-62. For the ML-66, which retained the ML structure, the EF voltage was reduced to −4 V, showing SET/RESET values of around ±3 V and stable electrical behavior, with an ON/OFF ratio of up to seven orders of magnitude. This demonstrates the importance of the ML design in the operation of RS devices. Full article
