Supramolecular nanoreactor as artificial mimetic enzyme is attracting a growing interest due to fine-tuned cavity and host-guest molecular recognition. Here, we design three 3d-4f metallo-supramolecular nanocages with different sizes active sites (Zn2Er4L14, Zn4Er6L26, Zn2Er8L38) based on "bimetallic cluster cutting" strategy. Three exhibit differential catalysis for the three-component aza-Darzens reaction without another additive, only Zn2Er8L38 largest most lanthanides centers has...
The purpose of this study was to identify possible association between noncontrast computed tomography (NCCT)-based radiomics features perihematomal edema (PHE) and poor functional outcome at 90 days after intracerebral hemorrhage (ICH) develop a NCCT-based radiomics-clinical nomogram predict 90-day outcomes in patients with ICH.In multicenter retrospective study, 107 were extracted from 1098 NCCT examinations obtained ICH. There 652 men 446 women mean age 60 ± 12 (SD) years (range: 23-95...
Aiming at low permeability, high water content light reservoir with a recovery rate higher than 20%, an improved air injection enhanced heat flooding technology is applied by combining the combustion reaction flow and flue gas mechanism. The method involves of into reservoir, which reacts crude oil temperatures ranging from 220 to 300 °C. This consumes part oil, enabling effective evaporation remaining oil. process combines flooding, using high-temperature oxidation reactions mobilize...
Microlens arrays were introduced into a QLED and the EQE of device was enhanced by factor 64%.
One of the attractive ways to develop efficient and cost‐effective inverted perovskite solar cells (PVSCs) is through use dopant‐free hole transporting materials (HTMs) with facile synthesis a lower price tag. Herein, two organic small molecules fluorene core are presented as HTMs in PVSCs, namely, FB‐OMeTPA FT‐OMeTPA. The designed such way they differ by replacing one benzene rings (FB‐OMeTPA) thiophene (FT‐OMeTPA), which leads significantly improved coplanarity manifested redshift...
Solution‐processed perovskite precursors, especially for MAPbBr 3 ‐assisted FAPbI crystallization, has been noted to achieve high power conversion efficiency (PCE) solar cells (PSCs). However, this low‐temperature processed (FAPbI ) x (MAPbBr 1− typical precursor derived from commercial products (FAI, PbI 2 , MABr, and PbBr suffers environmental sensitivity, poor film crystallinity less than ideal device reproducibility. Herein, 1– (0.80 ≤ 0.90)‐based planar inverted PSCs are fabricated,...
Abstract The performance of the blue quantum dot light‐emitting diodes (QLEDs) is largely affected by hole transport layers (HTLs). As a consequence deep valance band level dots (QDs), injection relatively difficult in QLEDs. To favor injection, HTLs with high mobility and deep‐lying highest occupied molecular orbital are desired. In this work, various their influence on QLEDs demonstrated. Devices poly(N‐vinylcarbazole) (PVK) HTL exhibit external efficiency while devices...
Halide perovskites stand out as promising materials for the realization of high-performance photodetectors. However, inherent instability and lead toxicity are still obstacles facing wide practical application In this work, first highly responsive lead-free perovskite photodiode based on Cs2Ag0.35Na0.65InCl6 nanocrystals (NCs) is demonstrated. The composition tuning strategy introduced to enhance device performance photodiodes. Employed with a structure composed ZnO:Al electron-transport...
Fiber-based nanogenerators have great potential applications in wearable electronics such as portable nanodevices, e-skin, and artificial intelligence system. Here, we report a kind of fiber-based electret nanogenerator (FENG) with semisupported core–shell structure. Owing to its unique structure, the open-circuit voltage short-circuit current FENG reach 40 V 0.6 μA, respectively, under short working distance (∼25 μm). No obvious degradation output performance long-time continuous work (>16...

Background: Spontaneous intracerebral hemorrhage (ICH) is one of the most common diseases with high mortality and disability rates. Early stratification patient risk could help to refine selection adjuvant therapy ultimately improve functional outcome. However, although radiomics models can predict outcome, their accuracy stability need be improved. And at present, there are no researches using explore correlation between perihematomal edema prognosis. We aimed evaluate gain value features...
