Summary: Research has shown that active magnetic-field control over lasing can be achieved in a periodic array of Co/Pt multilayer nanodots immersed in an IR-140 dye solution, allowing for external manipulation of plasmonic nanolasers. By exploiting the magnetic nature of the nanoparticles and mode tailoring, the transition between lasing action and non-lasing emission can be controlled, showcasing a new way to modulate plasmonic lasers. This study also demonstrates how the effects of magnetization on light, typically weak, can be observed in the lasing regime, paving the way for further exploration in topological photonics.

Summary: Stimuli-responsive luminescent hydrogels based on cellulose, ionic liquids, and lanthanide complexes are prepared by dissolution-regeneration processes. The hydrogels exhibit color-tunable emission from red to green by adjusting the molar ratio of Eu3+/Tb3+ in the lanthanide complexes. The hydrogels can serve as off-on-off luminescence switches by responding to Cu2+ ions through the photo-induced electron-transfer mechanism.

Summary: In this study, a pH and temperature dual-responsive hydrogel with unique irreversible on/off switching property was designed for high-efficiency desorption of dyes and regeneration of hydrogel. The pH-responsive sol-gel transition of the hydrogel enabled the transition of flocculation-adsorption for pollutants, widening the flocculation window. The maximum adsorption capacity of MB by TZP-hydrogel reached 1611 mg/g (20 degrees C), 1435 mg/g (40 degrees C) and 1100 mg/g (60 degrees C), with consistent adsorption isotherms. The synergistic effect of temperature and pH stimulus allowed for selective recovery of hydrogel from waste eluent, with a release rate of more than 91% at pH 1 and 60 degrees C. After 5 regeneration cycles, the maximum adsorption capacity of MB by TZP-hydrogel still reached 1551 mg/g (20 degrees C). Therefore, this work demonstrates the great potential of the unique irreversible on/off switching property for designing recyclable hydrogel adsorbent.

Summary: In this study, a stimuli-responsive MOF, 1. [CuCl], was found to exhibit reversible structural changes upon temperature variation, leading to significant alterations in gas adsorption properties. The mechanism behind this transition involves changes in coordination number and geometry of the Cu(I) ion, unlocking the rigidity of the framework and revealing its intrinsic flexibility.

Summary: A solvents-free molecular switch based on an amide skeleton was developed. The amide conformation was switched by treating the solid with HCl vapor and sublimation, and then reversed by sublimation with HCl removal. Crystal analysis confirmed the on/off process occurring in the gas state through sublimation rather than in the solution state.

Summary: The length of the alkyl side group plays a key role in the gas separation performance, with shorter side-alkyl groups leading to higher gas permeability. Surprisingly, vinyl-addition polynorbornene with methyl groups displayed both higher CO2 permeability and higher CO2/CH4 selectivity, contradicting traditional trade-offs. The solubility-controlled permeability of hydrocarbons is another notable feature, particularly in polymers with alkyl-substituents larger than ethyl-groups.

Summary: Demyelinating disorders, particularly multiple sclerosis (MS), have severe cognitive and physical effects on patients. This study developed a lipid nanocapsule system that encapsulates retinoic acid (RA) and superparamagnetic iron oxide nanoparticles (SPIONs), allowing for improved drug delivery to the central nervous system and interaction with cells involved in remyelination. The nanosystem demonstrated improved internalization by endothelial cells, increased permeability through the blood-brain barrier, and differentiation of oligodendrocyte progenitor cells. It also exhibited anti-inflammatory properties. These findings suggest the potential of this nanosystem as a promising therapeutic approach for MS.

Summary: Introducing retention enhancement oxide layers into the memristive stack can reduce switching speed by changing voltage and temperature distribution in the cell and influencing the rate-limiting step of switching kinetics. This trade-off between retention and switching speed is important for the rational engineering of memristive devices.

Summary: Intelligent electromagnetic wave absorbers (IEAs) are highly sought after for their ability to adapt to the complex and volatile application environments of the 5G era. However, there is currently a lack of research on the convertible electromagnetic wave absorption mode and its integrated design with external physical stimulations. This work presents a promising V2C-VO2(M) heterostructure that allows for intelligent switching in any conditions, with near wave-transmission characteristics at 25°C and wide effective absorption bandwidth at 70°C. The development of a multilayered electromagnetic functional device further facilitates the absorber's phase transition temperature.

Summary: This study fabricated biocompatible PLA honeycomb porous films with CO2-gas-triggered ON/OFF switching wettability, where the sensitive CO2 groups act as a switch controlling water entry into the pores. By adjusting the PLA/MET ratio, the CO2-sensitive groups can be precisely arranged, resulting in hydrophobic-hydrophilic conversion in the films.

Summary: This article proposes an improved SiC MOSFET turn-OFF model to address the issue of inaccurate prediction of turn-OFF losses under specific conditions. Experimental results demonstrate that the improved model can accurately predict the turn-OFF transient of SiC MOSFET. Further investigation reveals that driver resistance and load current are the decisive factors for achieving the special case.
