Summary: The method of induction flow levitation was used for the first time to synthesize porous sorbents based on silicon dioxide, enabling the direct synthesis of various types of silica in a continuous mode with high productivity. The developed method allowed for the evaporation of atoms from the silicon sample and the synthesis of catalytic systems based on ionic liquids with high catalytic activity. This research provides a promising method for the production of catalyst supports with high surface areas and functionalization possibilities.

Summary: Bacterial collagen, with its special arrangement and charged residues, can be used to nucleate three different inorganic materials and form collagen/mineral composites with more uniform particle size distribution. The gelation of silica during mineralization allows for the production of processable self-standing collagen composites. Therefore, combining bacterial collagen with minerals extends their applications in biomaterials and tissue engineering, particularly for bone regenerative scaffolds.

Summary: The dielectric and mechanical properties of polydimethylsiloxane-based compositions filled with silica and cured with metallosiloxanes were studied. The introduction of silica and formation of metal-siloxane networks significantly improved the dielectric properties of the material. Varying the structure and composition of the metallosiloxanes and the degree of silica filling allowed for effective control of the dielectric parameters. Changing the functionality and length of the rubber chain, as well as the curing rate, provided a wide range of mechanical properties. The cured systems have potential applications as flexible capacitive sensors or actuators.

Summary: Photocatalysis reactions using plasmon-sensitized titanium dioxide have shown promise in combating antibiotic-resistant bacteria. In this study, TiO2 nanostructures were grown within a high surface area and porous silica aerogel matrix, and their antibacterial activity against Escherichia coli was investigated under solar- and visible-light irradiations. The addition of silver-gold nanostars further enhanced the photocatalytic efficiency and antibacterial effect of the composite aerogels under visible light exposures.

Summary: Composite materials exhibit improved properties compared to pristine materials, especially when the filler is homogeneously dispersed in the matrix. This study suggests an innovative approach of forming a talc-like structure directly in a polymer matrix using a silanized polymer as the silicon source. Poly(ethylene glycol) methyl ether of different average molar masses (M-n = 350, 500, 750, 1900 g mol(-1)) were functionalized with (3-isocyanatopropyl)triethoxysilane and added to ethanolic solutions of magnesium nitrate. H-1-Si-29 CPMAS solid state NMR experiments revealed partial condensation of silane compounds, and FTIR analysis confirmed the presence of Si-O and Mg-O bonds, but further evidence is needed to prove the formation of the Si-O-Mg bond and the talc-like structure.

Summary: In the face of global warming and climate change, plants are subject to various biotic stresses, which hinder their growth and productivity. Nanotechnology, especially the utilization of silicon/silica nanoparticles, has emerged as a sustainable approach to tackle biotic and abiotic constraints in agriculture. These nanoparticles possess unique chemical and optoelectronic properties and can be easily synthesized using different methods for foliar, soil, or seed priming. Once taken up and transported by plants, they promote growth, development, and tolerance against environmental stresses, as well as pest attack and pathogen infection. Si/SiO2NPs not only facilitate nutrient delivery but also enhance plant resistance, making them an eco-friendly and cost-effective option for sustainable agriculture.
