The present study aimed to investigate the effect of emulsifier lysophospholipids (LP), enzymatically modified from soy phospholipids, on the growth performance, nutrient digestibility, lipid metabolism and meat quality of fattening rabbits. The LP was added in control (CON), LP1, LP2 and LP3 at 0, 200, 400 and 600 mg/kg, respectively. A total of 240 rabbits at approximately 52 d of age were divided into 4 groups with 6 replicates of 10 rabbits each.

Here, we utilized amorphous, irreversible and reversible cross-linked polyTA (PTA) as a matrix and lithium bis(trifluoromethane sulfonamide) (LiTFSI) as an electrolyte to prepare a stretchable (495%) and self-healing (94%) solvent-free elastomeric ionic conductor. The liquid-free ionic elastomer can be used as a stable strain sensor to monitor human activities sensitively under extreme temperatures.

Hypothesis: With the rapid development of economy and global industrialization, the problem of air pollution has become a worldwide topic. The efficient filtration of airborne particulate matters (PMs) is critical for human health and environmental sustainability.

Water-in-water (W/W) emulsions are of interest for various applications due to their inherent biocompatibility, ultralow interfacial tensions, and large interface thickness. However, it is still challenging to prepare stable W/W emulsions with tailored phase architectures compared to oil-in-water (O/W) and water-in-oil (W/O) emulsions. Here, we report a multilayer-stabilized W/W emulsion composed of poly(ethylene glycol)/dextran in the presence of DNA strands.

The properties of DNA TLCs were found to be manipulated by both the chemical structures of cationic and anionic surfactants and the DNA amount. Positively charged catanionic bilayer vesicles bond to negative DNA sites resulting in the transition from vesicles to long range ordered lamellar crystals of DNA-catanionic surfactants, as confirmed by cryo- and freeze-fracture (FF) TEM observations and small-angle X-ray scattering (SAXS) measurements.

Plasmonic microgels (PMgels) of the self-assembled gold nanorods (Au NRs) with side-by-side piles in ionic liquid microgels were prepared. Transmission electron microscopy (TEM) images revealed unique self-growth and self-arrangement of Au NRs in the microgel systems. The fabrication of PMgels occurs through co-assembling Au NRs and an ionic liquid microgel system, therefore differs from the fabrication of conventional plasmonic hybrid nanocomposites.

To endow valuable responsiveness to self-assemblies of Au nanoparticles (Au NPs), the magnetic Au nanoparticles (Au NPs)/CH(CH)N[CeClBr] (CTACe) mixtures were first prepared by using an emulsion self-assembly of a magnetic surfactant, CH(CH)N[CeClBr]. A versatile morphology of self-assemblies of Au NPs could be controlled by the counterions in surfactants including [CeClBr], [FeClBr], and Br as well as solvent. In particular, the magnetic counterion, [CeClBr], can induce self-growth of Au NPs in an emulsion self-assembly process due to the oxidability of [CeClBr].
