Summary: An effective co-assembly strategy has been demonstrated for creating complex photonic structures with interesting light reflections. By placing different bottlebrush block copolymers within shrinking droplets, a cooperative mechanism of microphase segregation and organized spontaneous emulsification is enabled, resulting in the fabrication of Janus microspheres with diverse dual optical characteristics. The reflected wavelengths of light are highly tunable simply by changing the formulation or molecular weight of the block copolymers.

Summary: In recent years, the application of ionic thermoelectric materials in converting waste heat into electricity has gained significant attention. This study demonstrates for the first time that nanofluidic membranes of vanadium pentoxide (V2O5) exhibit excellent ionic thermoelectric characteristics. The high Seebeck coefficient of the V2O5 membrane is attributed to the unidirectional transport of protons through the nanofluidic channels. Furthermore, functionalizing the membrane with ionic polymers like poly(4-styrenesulfonic acid) enhances its thermoelectric performance. The robustness and self-repair ability make V2O5-based nanofluidic membranes promising for future applications.

Summary: A novel nitrogen self-doped porous lamellar carbon material with superior electrochemical performance was prepared using metal-free phthalocyanine as a carbon source and nanosized SiO2 and SWCNTs as templates. The mesoporous structure was formed by the sacrificial template of nanosized SiO2, while the microporous structure was achieved through the pyrolysis of Pc/SWCNTs. The microscopic morphology and electrochemical performance of the porous carbon material could be regulated by adjusting the ratio between SWCNTs, nanosized SiO2, and phthalocyanine. The nitrogen self-doped porous lamellar carbon material demonstrated excellent stability and a specific capacity of 283.9 F/g at 1 A g-1, making it a promising supercapacitor anode material.

Summary: In this study, five different self-crosslinked polymerized ionic liquids (S-PILs) with identical mobile counterions were synthesized and their electrorheological (ER) effects were investigated. The results showed that S-PIL with phosphorus-containing ion spacers exhibited the weakest ER effect, while S-PIL with amino-containing ion spacers had the strongest ER effect. The reasons for these different ER effects were explained by calculating the activation energy of ion movement and the dissociation degree of counterions using conductivity and Raman spectroscopy data.

Summary: The increasing demand for computing power has pushed current lithographic methods to their limits, hindering further shrinkage of silicon chips using top-down approaches. The recent chip shortage has highlighted the world's excessive reliance on silicon and emphasized the need for silicon-free computing technologies, preferably at the molecular level. This study demonstrates an all-photonic device based on the emission dynamics of Eu3+ and Tb3+ ions in a Eu3+/Tb3+ co-doped organic-inorganic di-ureasil hybrid, showcasing a temperature-reprogrammable shift from a low-pass filter to a high-pass filter and paving the way for molecular analogs of conventional circuit components.

Summary: Renewable energy sources require efficient energy storage systems, and lithium-ion batteries are a standout option. However, there is still room for improvement in terms of safety and cycling stability. By implementing solid polymer electrolytes (SPEs) instead of the commonly used separator/electrolyte system, these issues can be addressed. This study focuses on the development of ternary SPEs based on specific host polymers, fillers, and ionic liquids to enhance the performance of lithium-ion batteries in terms of conductivity, stability, and cyclability.

To design new optical glasses, understanding the correlation between their chemical composition and physical properties is crucial. We demonstrate the feasibility of using fluoride phosphate glasses co-doped with Pr3+ and Yb3+ ions for temperature sensing. These glasses have high stability and act as luminescent thermometers without the need for recurring calibration. They exhibit competitive thermal sensitivity and uncertainty, making them promising for cost-effective and accurate temperature probes, advancing photonic technologies.
