Summary: A novel drug loading system, Au@Si-N-N-Si@SiO2, was constructed through layer-by-layer assembly. The system utilized core gold nanorods with near-infrared light-responsive photothermal properties, as well as a middle layer that generates free radicals upon heating to trigger drug release. An outer layer of silica was used to prevent drug leakage. The system demonstrated excellent photothermal effect under near-infrared laser irradiation and showed improved antitumor efficiency through NIR-triggered drug release, free radical generation, and photothermal effect.

Summary: This study explores the potential of soy protein isolate (SPI) and nicotinamide mononucleotide (NMN) complexes as pH-responsive stabilizers for Pickering emulsions. The optimal SPI/NMN composite particle properties and enhanced emulsion stability were achieved at 1.5 wt% NMN concentration, pH 7 with the addition of sodium chloride. The SPI/NMN-embedded ibuprofen demonstrated pH-responsive behavior, with increased release in alkaline conditions and reduced release in acidic ones, showing potential for pH-targeted drug delivery.

Summary: A series of oleogels stabilized by zein and plasticized with glycerol were investigated for their rheological and microstructural properties. The plasticized zein oleogel exhibited a weak-link regime with a protein network that became denser with increasing glycerol concentration. Higher zein concentration resulted in a denser oleogel network. The rheological behavior of the oleogels showed a reversible transition from solid-like to liquid-like upon heating, starting at 75 degrees C.

Summary: This study presents a dual-responsive and versatile lubricating emulsion composed solely of water, eco-friendly ester base oil, and synthetic cationic emulsifier. The emulsion exhibits efficient anticorrosion, antibiosis, and light-and magneto-responsiveness, thanks to the unique surfactant with azobenzene moiety, [CeCl3Br]- anion, and methylimidazole head-group. By exploiting the reversible photo-triggered hydrophobicity of the surfactant, an on-demand separation and recycling of emulsion components can be achieved, accompanied by a significant reduction in friction. Additionally, the emulsion lubricant demonstrates magnetically controlled migration and adaptivity to high normal loads, making it promising for applications in various industrial systems and smart devices.

Summary: Emulsion gel was developed to improve the texture, taste, and functionality of food products. The stability of emulsions is often desired, but it is difficult for emulsion gels due to the formation of tangled networks. To address this issue, a biobased emulsion gel stabilized by modified cellulose nanofibrils with a CO2 responsive surfactant was reported. The emulsification/de-emulsification process can be controlled by the CO2 responsive property of the surfactant.

Summary: Gold nanostars (GNSs) as a photothermal agent have shown great potential for melanoma treatment. Delivery of GNSs using fast dissolving microneedles (MNs) provides a promising approach for painless and convenient therapy. PEG-stabilized GNSs can absorb near-infrared light and release heat, showing an instant lethal effect on melanoma cells upon laser irradiation. Loading GNSs in PVP MNs enables effective transdermal delivery and fast dissolution, resulting in elevated skin temperature after laser irradiation.

Summary: The study found that a single exposure to social defeat in rats resulted in profound alterations in dopamine release in the nucleus accumbens, as measured by fast-scan cyclic voltammetry. The defeated rats showed enhanced dopamine responses compared to control animals, which was associated with increased immobility time in the forced swim test. The administration of a dopamine D2 receptor antagonist resulted in increased dopamine release, but the effect was less pronounced in defeated rats compared to control animals. These findings suggest a promising path for understanding the neurobiological mechanisms underlying stress-induced behavioral abnormalities.

Summary: A series of PEG-functionalized silica nanoparticles with various molecular weights were prepared and used for the elaboration of temperature-responsive Pickering emulsions. The stability of the emulsions is determined by the hydrophilic/hydrophobic balance of the PEG/mPEG chains, and the distribution of the chains at the oil-water interface is modified with temperature, leading to a clear temperature-triggered destabilization of the emulsions.

Summary: Gas-solid fluidized-bed systems have advantages in terms of chemical reaction efficiency and temperature control, making them widely used in industrial applications. However, the design, scale-up, and optimization of these complex units are limited by the lack of deep physical understanding. Non-invasive and non-intrusive diagnostic techniques provide a way for researchers to study these systems without affecting the flow field or directly contacting the medium under study.

Summary: Fluidization at low pressure offers significant benefits for the fine chemical industry. This study investigates the behavior of bubbles and bed expansion under low pressure conditions. It is found that lower pressure leads to larger bubbles, increased bubble quantity, and higher aspect ratio. The predictability is affected by the inhomogeneous fluidization, but low pressure fluidization can generate similar bubble sizes with lower fluidizing mass compared to atmospheric pressure.
