Summary: A novel high-efficiency absorber was developed through the composition combination and structural design of materials. Hollow flower-like MoO2/CoNi/NPC microspheres were constructed using supramolecular self-assembly in a water-in-oil system and carbonization. The microspheres exhibited outstanding electromagnetic wave absorption performance, with a minimum reflection loss of -54 dB and an effective absorption bandwidth of 4.72 GHz at a filling ratio of 35 wt%. The excellent absorption performance was attributed to the 3D flower-like hollow structure, enhanced impedance matching, and strong polarization loss induced by the double-layer structure and Schottky contact.

Summary: The study focuses on the self-assembly of two-dimensional nanostructures using evaporating sessile drops containing surface active colloids. It examines how evaporation kinetics under controlled humidity conditions affect the microstructure of colloidal monolayers. Experimental findings show different regions forming at the water-vapor interface under saturated humidity conditions, impacting the interface microstructure.

Summary: In this study, 3D flower-like templated layered double hydroxides (LDH) and graphene (rGO) were prepared on the surface of a caprolactam-modified casein micelle template for integration with casein latex by a blending-casting method. The casein-based Temp@LDH-rGO composite latex showed significant improvement in flame retardant and smoke suppression performance, making it a highly effective option for functional coatings in diverse fields.

Summary: Monodisperse, flower-like liquid crystalline polymer particles were successfully synthesized using precipitation polymerization of a LC mixture with redox-responsive diacrylates. The presence of a small amount of redox-responsive diacrylates induced the formation of flower-like shapes, with particle morphology influenced by polymerization temperature. Time-resolved TEM showed that particle morphology was determined early in the polymerization process, with subsequent growth unaffected by changes in morphology. Flower-like particles degraded faster under reducing conditions due to their higher surface-to-volume ratio.

Summary: The study demonstrates that a two-component system of tetrahedral patchy particles, where bonding is allowed only between particles of different types to select even-member rings, can more easily achieve self-assembly into diamond crystals. The crystallization process in the two-component system is thermodynamically and kinetically enhanced.

Summary: This study reveals that microparticle morphologies can be controlled by using monosaccharide esters, with d- and l-glucose stearoyl esters inducing left-handed and right-handed shapes, while other monosaccharides cannot form spiral particles, generating other shapes. The numbers of side chains and bond orientations contribute to obtaining solid or porous flower-like microparticles.

Summary: ZnO/PPy composites with flower- and rod-like structures were successfully fabricated in this study, showing that the MWA ability was significantly enhanced after the introduction of PPy. Among them, the rod-like composites exhibited superior MWA properties compared to the flower-like ones, attributed to the improved dielectric properties and multiple reflections of incident electromagnetic waves.
