Materials with low intrinsic lattice thermal conductivity are crucial in the pursuit of high‐performance thermoelectric (TE) materials. Here, the TE properties of PbBi2Te4‐xSex (0 ≤ x ≤ 0.6) samples are systematically investigated for the first time. Doping with Se in PbBi2Te4 can simultaneously reduce carrier concentration and increase carrier mobility. The Seebeck coefficient is significantly increased...
Herein, a type of light‐ and heat‐driven flexible supramolecular polymer with reversibly long‐lived phosphorescence and photochromism is constructed from acrylamide copolymers with 4‐phenylpyridinium derivatives containing a cyano group (P‐CN, P‐oM, P‐mM), sulfobutylether‐β‐cyclodextrin (SBCD), and polyvinyl alcohol (PVA). Compared to their parent solid polymers, these flexible supramolecules based...
The development of high‐energy‐density solid‐state lithium metal battery has been hindered by the unstable cycling of Ni‐rich cathodes at high rate and limited wide‐temperatures adoptability. In this study, an ionic liquid functionalized quasi‐solid‐state electrolyte (FQSE) is prepared to address these challenges. The FQSE features a semi‐immobilized ionic liquid capable of anchoring solvent molecules...
Organic scintillators with efficient X‐ray excited luminescence are essential for medical diagnostics and security screening. However, achieving excellent organic scintillation materials is challenging due to low X‐ray absorption coefficients and inferior radioluminescence (RL) intensity. Herein, supramolecular interactions are incorporated, particularly halogen bonding, into organic scintillators...
Poly(I:C) is a synthetic analogue of dsRNA capable of activating both TLR3 and RLRs, such as MDA‐5 and RIG‐I, as pathogen recognition receptors. While poly(I:C) is known to provoke a robust type I IFN, type III IFN, and Th1 cytokine response, its therapeutic use as a vaccine adjuvant is limited due to its vulnerability to nucleases and poor uptake by immune cells. is encapsulated poly(I:C) into lipid...
Sodium–potassium (NaK) alloy electrodes are ideal for next‐generation dendrite‐free alkali metal electrodes due to their dendrite‐free nature. However, issues such as slow diffusion kinetics due to the large K+ radius and the loss of active potassium during the reaction severely limit its application. Here a novel cobalt/nitrogen‐doped carbon material is designed and it is applied to the construction...
Three‐dimensional (3D) printing methods, such as vat photopolymerization (VPP) and direct‐ink‐writing (DIW) processes, are known for their high‐resolution and multimaterial capabilities, respectively. Here a novel hybrid 3D printing technique that combines the strengths of VPP and DIW processes to achieve multimaterial and high‐resolution printing of functional structures and devices, is presented...
Macrocyclic confinement‐induced supramolecular luminescence materials have important application value in the fields of bio‐sensing, cell imaging, and information anti‐counterfeiting. Herein, a tunable multicolor lanthanide supramolecular assembly with white light emission is reported, which is constructed by co‐assembly of cucurbit[7]uril (CB[7]) encapsulating naphthylimidazolium dicarboxylic acid...
Synaptic devices that mimic biological synapses are considered as promising candidates for brain‐inspired devices, offering the functionalities in neuromorphic computing. However, modulation of emerging optoelectronic synaptic devices has rarely been reported. Herein, a semiconductive ternary hybrid heterostructure is prepared with a D‐D’‐A configuration by introducing polyoxometalate (POM) as an...
Optical lenses require feature resolution and surface roughness that are beyond most (3D) printing methods. A new continuous projection‐based vat photopolymerization process is reported that can directly shape polymer materials into optical lenses with microscale dimensional accuracy (< 14.7 µm) and nanoscale surface roughness (< 20 nm) without post‐processing. The main idea is to utilize frustum...

In article number 2300517, Yong Chen and co‐workers introduce a continuous vat photopolymerization method for optical lens production. This approach achieves nanoscale surface roughness and microscale shape accuracy. Utilizing a zooming‐focused projection system, the authors continuously modify ultraviolet mask images, allowing for controlled frustum layer stacking and the...
3D objects with features spanning from microscale to macroscale have various applications. However, the fabrication of such objects presents challenges to additive manufacturing (AM) due to the tradeoffs among manufacturable feature resolution, maximum build area, and printing speed. This paper presents a projection‐based AM process called hopping light vat photopolymerization (HL‐VPP) to address...
Two‐photon supramolecular assembly with near‐infrared (NIR) fluorescence emission is constructed from tetraphenylethene derivative possessing methoxyl and vinyl pyridine salt (TPE‐2SP), cucurbit[8]uril (CB[8]), and β‐cyclodextrin modified hyaluronic acid (HA‐CD). The obtained experimental results indicate that the TPE‐2SP exhibits a very weak fluorescence emission at 650 nm, and then complexes with...
Solution‐processed semiconductor single‐crystal patterns possess unique advantages of large scale and low cost, leading to potential applications toward high‐performance optoelectronic devices. To integrate organic semiconductor micro/nanostructures into devices, various patterning techniques have been developed. However, previous patterning techniques suffer from trade‐offs between precision, scalability,...
Cellular microenvironments are generally sophisticated, but crucial for regulating the functions of human pluripotent stem cells (hPSCs). Despite tremendous effort in this field, the correlation between the environmental factors—especially the extracellular matrix and soluble cell factors—and the desired cellular functions remains largely unknown because of the lack of appropriate tools to recapitulate...
