Abstract Traditional light‐driven metal‐organic‐frameworks (MOFs)‐based micromotors (MOFtors) are typically constrained to two‐dimensional (2D) motion under ultraviolet or near‐infrared light and often demonstrate instability susceptibility ions in high‐saline environments. This limitation is particularly relevant employing water purification, as real wastewater frequently coupled with high salinity. In response these challenges, ultrastable MOFtors capable of three‐dimensional (3D) a broad...

Flexible organic crystals represent a novel class of smart materials that open many opportunities for optical applications. While it has been established elastic or plastic deformation slender molecular can be commonly induced by external intervention, grow in bent curled shapes naturally are rarely reported. This study introduces an extraordinarily flexible crystalline fibrous material, (Z)-3-(2,3-dichloropyridin-4-yl)-2-(3,5-dimethylphenyl)acrylonitrile (DPA), crystallizes both as straight...

Flexible crystals with unique mechanical properties have presented enormous applications in optoelectronics, soft robotics and sensors. However, there been no reports of low‐temperature‐resistant flexible second‐order nonlinear optical (NLO). Here, we report the chiral Schiff‐base capable efficient second harmonic generation (SHG). Both enantiomers racemic modifications these are mechanically two directions at both room temperature ‐196 °C, although their responses differ. The display SHG an...

Abstract In this work, 44 metal–organic frameworks (MOFs) are screened for efficient electrocatalytic nitrogen reduction reaction (eNRR). The isosteric heats of N 2 adsorption on the metal active centers MOFs calculated by grand canonical Monte Carlo method. It is found that p‐block‐elements exhibit highest affinity among all elements, implying their excellent catalytic potentials eNRR. Furthermore, Al element preferentially chosen as center (MIL‐53 (Al)) owing to its relatively low toxicity...

The generalized back propagation algorithm is extended to multi-layer higher-order neural networks (HONNs). performance of HONNs presented. Two basic structures, the standard form and polynomial form, are discussed. these two structures compared using classical TC test case, geometric rotation problem. Simulation results show that both types constructing strategies can recognize noisy data under up 70% irrational 94%. effect number hidden neurons discussed.< <ETX...

Emerging applications in Printed Circuit Board (PCB) routing impose new challenges on automatic length matching, including adaptability for any-direction traces with their original preserved interactiveness. The can be addressed through two orthogonal stages: assign non-overlapping regions to each trace and meander the within reach target length. In this paper, mainly focusing meandering stage, we propose an obstacle-aware detailed approach optimize utilization of available space achieve...

This study employs machine learning and the difference-in-differences (DID) approach to analyze impact of China's "Low-Carbon City" pilot policy on asset efficiency A-share listed companies. The findings indicate that has generally suppressed corporate efficiency, particularly in state-owned enterprises large-scale also reveals policy's is not significant located eastern regions. Further robustness checks are conducted through predictive analysis using random forest model, confirming...

Ultrasound can non-invasively penetrate deep into brain for neuromodulation and has demonstrated good potential clinical application. Excitation or inhibition of neurons by ultrasound been reported, but the underlying mechanisms are largely unknown. So far most in vitro studies have focused on activation individual with calcium imaging. As focal region is typically millimeter submillimeter size, it important to investigate yet so unclear how mechanical effects would influence synaptic...

In China, where sports and are integral components the educational curriculum, importance understanding specific impacts cannot be overstated. This study focuses on technical vocational college setting Fujian, aiming to fill a crucial research gap address need for tailored programs. Basketball widely promoted accepted major...

Abstract Organic–inorganic metal halides (OIMHs) possess low preparation costs and high photoluminescence quantum yield. Within a specific range, the temperature‐dependent nature of OIMHs' luminescent lifetime facilitates temperature sensing thermal imaging functionalities.
