“…Its macromolecules ( Figure 1 ) are rich in hydroxyl, carboxyl, and other functional groups, resulting in good adsorption properties and a strong ability to coordinate with heavy metal ions [ 18 , 19 ]. The addition of xanthan gum to PVA elastomeric material has an important influence on its properties in terms of structural compatibility and polymer morphology [ 10 , 20 , 21 , 22 , 23 ].…”

The design of hydrogel networks with tuned properties is essential for new innovative biomedical materials. Herein, poly(vinyl alcohol) and xanthan gum were used to develop hydrogels by the freeze/thaw cycles method in the presence of oxalic acid as a crosslinker. The structure and morphology of the obtained hydrogels were investigated by means of scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and swelling behavior. The SEM analysis revealed that the surface morphology was mostly affected by the blending ratio between the two components, namely, poly(vinyl alcohol) and xanthan gum. From the swelling study, it was observed that the presence of oxalic acid influenced the hydrophilicity of blends. The hydrogels based on poly(vinyl alcohol) without xanthan gum led to structures with a smaller pore diameter, a lower swelling degree in pH 7.4 buffer solution, and a higher elastic modulus. The antimicrobial activity of the prepared hydrogels was tested and the results showed that the hydrogels conferred antibacterial activity against Gram positive bacteria (Staphylococcus aureus 25923 ATCC) and Gram negative bacteria (Escherichia coli 25922 ATCC).

“…This is due to the larger molecular weight formed by adding D-mannitol, which makes it difficult to dissolve the sample in water, resulting in enrichment. The addition of D-mannitol increases the porosity of magnesium oxysulfate cement-boron mud blends, which can be due to the pores in the system being filled due to enrichment [37]. The structure of the system is affected by the addition of the modifier.…”

At present, the utilization of boron resources in China is increasing, and the problem of boron tailing pollution is becoming increasingly serious. To fundamentally solve the problem of boron tailing, many scholars at home and abroad have mainly studied the curing effect in terms of compressive strength, and little research has been carried out into the solidification effect and hydration products. This study explored the effects of adding different alcohol-based modifiers on the hydration products of magnesium oxysulfate cement-boron mud mixture, the microstructure, physical properties and curing effects of the samples. The results show that magnesium oxysulfate cement is beneficial to the solidification of boron in boron mud due to its low-alkali. Adding an alcohol-based modifier can increase the compressive strength of magnesium oxysulfate cement-boron mud blends. After adding acrylic acid and D-Mannitol, the 28-day compressive strength of the sample increased by 44.7 MPa. The blending of alcohol-based modifiers has a very good effect on the curing of boron in the whole system.

Heterogeneous reactions of ubiquitous acidic gases on the surface of mineral dust particles change particulate acidity and therefore affect the atmosphere, soil, and water environments during long-distance transport. Notwithstanding, interactions of inorganic and organic acidic gases in the heterogeneous reactions with aerosols remain poorly understood. In this study, reactions of sulfur dioxide (SO2) and acrylic acid on the surface of titanium dioxide (TiO2) particles under different conditions are investigated using diffuse reflectance infrared Fourier transform spectroscopy. Our analysis shows that in the single-component experiments with only SO2 or acrylic acid, wet condition inhibits the formation of sulfite compared with the dry condition; light can promote the formation of sulfuric acid and sulfate, but has little effect on the reaction of acrylic acid. In the mixed experiments with both SO2 and acrylic acid, acrylic acid can inhibit the heterogeneous reaction of SO2 by competing Lewis acid sites, Lewis basic sites, and OH active sites on the surface of particles, whereas SO2 has little effect on acrylic acid. When there is light in the mixed experiments, photo-excited reactive oxygen species can facilitate the production of sulfuric acid, which displaces acrylic acid, resulting in a decrease in acrylate and an enhancement in adsorbed acrylic acid. The results reveal the interaction of different acidic gases on the surface of particles and advance the understanding of the heterogeneous reaction of trace gases in complex atmospheric environments.
