Silicon is widely used as a "quality element" and "stress resistance element" in crop production and the remediation of heavy metal-contamination soils. Compared to inorganic silicon, organosilicon has unique properties such as amphiphilicity, low surface energy and high biocompatibility. Our previous research has confirmed the effectiveness of organosilicon-modified fertilizers in inhibiting Cadmium (Cd) absorption in wheat. Therefore, it is of great importance to further explore the potential mechanisms and comprehensive benefits of organosilicon. In this study, the microbiological and molecular mechanisms by which organosilicon reduces Cd concentration in wheat compared to inorganic silicon were investigated in depth. The findings indicated that, in comparison with inorganic silicon, organosilicon exhibited a more remarkable efficacy. Specifically, it was more effective in reducing the Cd concentration in wheat grains, achieving a reduction range of 35–39 % as opposed to the 23–28 % reduction achieved by inorganic silicon. Moreover, it manifested a greater ability to mitigate health risks, with a reduction range of 33–42 % compared to the 25–30 % reduction of inorganic silicon. Furthermore, organosilicon contributed to a significant increase in wheat yield, with a growth range of 11–14 % in contrast to the 8–11 % increase from inorganic silicon. Additionally, it enhanced the quality of the grains, substantially improving the protein content and amino acid content. The comparative advantages of organosilicon over inorganic silicon would be firstly due to the reduction of the bioavailability of soil Cd by increasing the available silicon content in the soil and improving the soil microbial ecology (increasing the abundance of Bacillus , Pseudomonas , Massilia and Talaromyces and reducing the enrichment of Fusarium ). Secondly, organosilicon achieved vacuolar compartmentalization of Cd by upregulating the expression of the ABC transporter gene ( TaABCB7 ), thereby alleviating Cd toxicity and restricting Cd transport from leaves to grains. Meanwhile, organosilicon increased the wheat yield by optimizing the availability of soil nutrients and enhancing photosynthesis. These results demonstrate the immense potential of organosilicon in mitigating heavy metal contamination in crops.

An SPE cartridge based on an ampholine-functionalized hybrid organic–inorganic silica sorbent has been adopted for the analysis of aromatic amines including 4-aminobiphenyl, benzidine, 2-naphthylamine, p -chloroaniline, 2,4,5-trimethylaniline, and 3,3′-dichlorobenzidine. Crucial variables governing the extraction efficiency of the material such as the pH of sample, sample loading volume, solvent used for elution, and elution volume have been thoroughly optimized. The adsorption capacities for the six aromatic amines ranged from 0.17 to 1.82 μg/mg. The recoveries of aromatic amines spiked in textile samples ranged from 78.9 to 103.0%, with RSDs of 1.1–11.9% ( n = 3). Moreover, the extraction efficiency of the ampholine-functionalized hybrid organic–inorganic silica sorbent was at least comparable with that of Oasis WCX.

In this work, a novel multifunctional film with durable antifogging performance and remarkable optical property is designed. By doping and hybridization to build an organic–inorganic siloxane network, the surface achieves long-lasting wettability and superhydrophilicity with a water contact angle of 0°, which is maintained within 10° for over 130 days. The low refractive index endows the hybrid film with excellent optical property, which the average transmittance (380–1100 nm) of the film is 97.60% with the peak transmittance of 99.48%. By this design, the film performs well in the felt abrasion test, water impact test, X-cut tape test, tape-peeling test, chemical stability test, and anti-dust test. Due to the abundant hydroxyl radicals on the surface, the film also exhibits excellent performance, achieving 92.73% degradation of methylene blue solution (10 ppm) and 39.53% degradation of rhodamine B (10 ppm) with good reproducibility in cyclic measurements.

In this work, an ampholine-functionalized hybrid organic–inorganic silica sorbent was successfully used to extract melamine from a milk formula sample by a hydrophilic interaction solid-phase extraction protocol. Primary factors affecting the extraction efficiency of the material such as extraction solvent, elution solvent, sample loading volume, and elution volume have been thoroughly optimized. Under the optimized hydrophilic solid-phase extraction conditions, the recoveries of melamine spiked in milk formula samples ranged from 86.2 to 101.8% with relative standard deviations of 4.1–9.4% ( n = 3). The limit of detection (S/N = 3) was 0.32 μg/g. The adsorption capacity toward melamine was 30 μg of melamine per grams of sorbent. Due to its simplicity, rapidity and cost effectiveness, the newly developed hydrophilic solid-phase extraction method should provide a promising tool for daily monitoring of doped melamine in milk formula.

Corrosion is a thorny problem when steel reinforcement in sand–based autoclaved aerated concrete (SAAC) is in use. In this study, potassium silicate was used as the base material and muscovite and zinc powder were added as fillers to improve the coating properties. In addition to physical and mechanical properties, electrochemical tests including potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) were performed on the coatings. The phase composition, chemical composition and morphological differences of different coatings were also characterized. The results showed that zinc powder increased the density of the muscovite–potassium silicate coating and significantly improved the corrosion resistance and mechanical properties of the coatings. The prepared coatings exhibited stable qualities with no heat absorption and release before 365 °C. The adhesive strength and impact resistance of the coatings were as high as 2.43 MPa and 50 kg cm, respectively. The electrochemical test results showed that the coating resistance ( R c ), charge-transfer resistance ( R ct ), and polarization resistance ( R p ) of the C-5.5–55–40 coating were 23578, 3.542 × 10 5 , and 2.911 × 10 5 Ω cm 2 , respectively, which exhibited the optimal corrosion resistance.
