The Layered Encapsulation of Vitamin B2 and β-Carotene in Multilayer Alginate/Chitosan Gel Microspheres: Improving the Bioaccessibility of Vitamin B2 and β-Carotene

Peilong Liao et al.

Summary: This research highlights the potential of alginate multilayered gel microspheres for layered encapsulation and simultaneous delivery of vitamin B-2 and beta-carotene. Chitosan was used to enhance the stability and controlled release ability of the gel microspheres. The results showed that the multilayered gel microspheres had pH response characteristics and excellent thermal stability. The concentration of sodium alginate and the number of layers had significant effects on the mechanical properties and particle size of the gel microspheres. Fourier-transform infrared spectroscopy and X-ray diffraction analyses confirmed the encapsulation of vitamin B-2 and beta-carotene within the gel microspheres. The simultaneous encapsulation of these two compounds improved their bioaccessibility and bioavailability.

Enzymolysis-treated wood-derived hierarchical porous carbon for fluorescence-functionalized phase change materials

Yaqiong Li et al.

Summary: The current obstacles hindering the development and industrial application of phase change materials (PCMs) include low thermal conductivity, high cost, leakage, and poor mechanical performance. This study aims to enhance the thermal conductivity and power capacity of PCMs by using abundant biomass-derived carbon as supports. Cellulase is used to hydrolyze cellulose in wood and create micropores, which leads to effective construction of adsorption sites during the subsequent pyrolysis process. The resulting hierarchical porous carbon infiltrates polyethylene glycol (PEG) and enhances crystallization. This strategy combines good mechanical performance, high energy storage capacity, anisotropic thermal conductivity, and improved thermal stability. Furthermore, the composite PCMs loaded with carbon quantum dots (CQDs) integrate fluorescent function and thermal energy storage, providing potential applications in specific equipment.

Ag modification of SBA-15 and MCM-41 mesoporous materials as sorbents of thiophene

Yang Liu et al.

Summary: This paper investigates the adsorption performance of silver-modified mesoporous materials in removing thiophenic compounds. The results show that the adsorption of thiophene by the sorbents involves S-Ag and pi complexation reactions, and the adsorption efficiency is greatly affected by benzene. XPS analysis reveals that silver interacts strongly with the carrier and forms Ag-O-Si bonds as the active centers for thiophenic compounds. The Mulliken charges of sulfur atoms have an impact on the interactions between silver and thiophene sulfur compounds.
