Summary: In this study, well-defined powder micro-granules with interstitial nanopores were achieved through one-step evaporative jamming of colloidal silica particles in contact-free spray droplets. The anomalous freezing behavior of confined water in these microspheres synthesized using spray drying was investigated, revealing a significant lowering of the freezing point to around -45 degrees C due to the confinement effect. The results from thermoporometry were supported by structural details obtained through gas adsorption measurements and small-angle x-ray scattering.

Summary: A pH-responsive drug carrier was developed for controllable drug release in the gastric environment by grafting hydroxyapatite into a chitosan/nano-clay matrix. The co-precipitation method led to the penetration of hydroxyapatite nanoparticles inside the matrix, reducing drug release rate. The nanocomposite showed high sensitivity to pH and significantly decreased drug release rate in both gastric and intestinal environments.

Summary: Super-wetting membranes with catalytic performance were fabricated using Fe3O4-loaded attapulgite (FATP) nanofibers. These membranes possess hydrophilicity and micro-nano roughness, which resist oil fouling and act as a catalyst for the Fenton-like reaction. During oil-in-water filtration, more than 99.5% of oil droplets can be rejected, and membrane permeance remains at 62% of its initial value. After hydraulic cleaning, the permeance recovers to 85%, and the remaining 10.9% can be restored through the Fenton-like reaction. This study provides insights into the catalytic mechanism of membranes after oil fouling.

Summary: Silicone nanoparticles were deposited onto melamine sponge and modified with polypyrrole and Au nanoparticles to fabricate highly saltresistant solar evaporators for stable long-term desalination and water harvesting. These solar evaporators have a superhydrophilic hull for water transport and solar desalination, and a superhydrophobic nucleus for reducing heat loss. They achieved spontaneous rapid salt exchange and reduction in salt concentration gradient due to ultrafast water transport and replenishment in the superhydrophilic hull with a hierachical micro-/nanostructure, effectively preventing salt deposition during interfacial solar-driven evaporation (ISE). These solar evaporators demonstrated long-term stable evaporation performance and the ability to collect fresh water without any salt precipitation.

Summary: The adhesion of liquid foods on their packaging materials has become a major concern due to the significant waste and pollution it causes. Food grade superhydrophobic coatings offer a promising solution, although their application has been limited by low mechanical stability and complex preparation methods. In this study, a food grade superhydrophobic coating was developed using edible paraffin wax, polydimethylsiloxane-modified attapulgite natural nanorods, and a food grade silicone adhesive. The coating exhibited good static and dynamic superhydrophobicity, as well as excellent mechanical and chemical stability. It also showed repellency towards various liquid foods, including hot ones, and could be applied to a wide range of food packaging materials. Therefore, the superhydrophobic coatings have great potential for anti-adhesion of liquid foods in the food packing industry.

Summary: By modifying polydopamine (PDA) on the surface of molybdenum disulfide (MoS2), small-sized copper nanoparticles were grown uniformly to form MoS2/PDA@Cu nanozyme. This nanozyme exhibited excellent peroxidase-like activity and antibacterial properties, showing a more pronounced inhibitory effect on bacterial growth with the addition of H2O2. The maximum reaction rate (V-max) of the MoS2/PDA@Cu nanozyme is significantly higher than that of horseradish peroxidase (HRP), and it also demonstrated excellent biocompatibility, hemocompatibility, and potential anticancer properties.
