Summary: In this study, an acid-free green synthesis strategy was proposed for the one-pot synthesis of highly ordered mesoporous materials via the radical route with singlet oxygen promotion. The synthesis approach overcomes the challenge in the direct one-pot acid-free synthesis of highly ordered materials and provides a facile and environmentally friendly route for the future large-scale production of ordered mesoporous materials.

Summary: Functional mesoporous carbonaceous nanomaterials with large pores have wide accessibility and can transport chemicals efficiently in various fields including biomedical applications, gas separation, catalysis, sensing, and energy storage and conversion. The assembly of monomicelles, composed of block copolymers/surfactants and precursor species, has been used to control the nanostructure and mesoporosity of carbonaceous nanomaterials. This method allows for a high degree of control over the final product's structure, making it possible to shape the nanomaterial into unique nanostructures that are otherwise difficult to synthesize using conventional templating methods.

Summary: In this paper, a hydrodynamically coupled phase-field model for triblock copolymer melts is formulated, and a time-marching scheme for it is developed based on the combination of the projection method and the IEQ method. A new nonlocal variable and its time evolution equation are introduced to simplify the implementation, resulting in a fully decoupled scheme. The scheme only needs to solve several completely independent elliptic equations with constant coefficients at each time step, while maintaining strict unconditional energy stability. Numerical simulations of triblock polymer materials under applied shear flow in 2D and 3D are performed to demonstrate the effectiveness of the developed numerical scheme.

Summary: The conversion of waste plastic into high-value-added chemicals is considered a promising approach to address global plastic pollution and promote the circular economy. This study developed a partial calcination strategy to create a zinc oxide/UiO66-NH2 heterojunction for photocatalytic valorization of plastic. The obtained heterojunction exhibited high activity for converting polylactic acid and polyvinyl chloride into acetic acid, along with hydrogen production. This work provides insights into the process of photocatalytic valorization of plastic and offers a feasible strategy for designing heterojunction photocatalysts.

Summary: Polyacrylic acid-coated magnetic nanoparticles (MNP@PAA) were synthesized and evaluated as draw solutes in forward osmosis (FO). The synthesized MNP@PAA particles demonstrated spherical shapes of maghemite Fe2O3 and superparamagnetic properties, allowing for draw solution (DS) recovery using an external magnetic field. The MNP@PAA particles exhibited an osmotic pressure of approximately 12.8 bar and an initial water flux of 8.1 LMH. After being captured by an external magnetic field, rinsed in ethanol, and re-concentrated as DS in repetitive FO experiments, the re-concentrated DS showed an osmotic pressure of 4.1 bar and an initial water flux of 2.1 LMH. These results verify the feasibility of using MNP@PAA particles as draw solutes.

Summary: Roe refers to the eggs or whole gonads of fish, crustaceans, mollusks, and echinoderms. It is not only a source of nutrients for animals in the sea, but also a popular food among humans. From cod roe to caviar, roe is consumed in various forms and holds a rich gastronomic history. With its high omega-3 fatty acid content and unique taste, roe is valued for its nutrition and culinary uses. This article explores the diverse types of roe beyond sturgeon, such as flat fish, codfish, mullet, smelt, trout, herring, crab, shrimp, and octopus, as well as caviar substitutes made from fish meat and seaweeds. It argues for the sustainable and creative use of roe, including enhancing the umami flavor of vegetable and green dishes.

Summary: This study reports a feasible strategy for synthesizing high-entropy photocatalysts-based fibrous membranes with a dual function of capturing and upcycling plastic. The researchers found that polyacrylonitrile nanofiber templates enable the growth of highly arranged high-entropy metal tungstates (FeCoNiCuZn)WO4, and the lattice distortion in XWO4 modulates the band gap structure, leading to enhanced upgradability of captured polylactic acid. This research provides important insights into tailoring the structure and composition of high-entropy photocatalysts for plastic upcycling.
