Abstract Constructing responsive and adaptive materials by dynamic covalent bonds is an attractive strategy in material design. Here, we present a kind of polyureas which can be prepared from the highly efficient polyaddition reaction pyrazoles diisocyanates at ambient temperature absence catalyst. Owing to multiphase structural design, poly(pyrazole-ureas) (PPzUs) show excellent mechanical properties unique crystallization behavior. Besides, crosslinked PPzUs successfully recycled upon...
Thermosetting polymers possess excellent environmental resistance and mechanical properties but cannot be reprocessed due to their covalently cross-linked structures. Recycling of thermosets via the implantation dynamic covalent bonds offers a promising solution. Here, we report direct catalyst-free ester metathesis N-acyloxyphthalimide (NAPI) at about 100 °C without requirement hydroxyl groups its utilization for fabrication adaptable networks (CANs). NAPI has interesting sigmoid kinetics...
An understanding of the factors limiting open-circuit voltage (Voc) and related photon energy loss mechanisms is critical to increase power conversion efficiency (PCE) small-molecule organic solar cells (OSCs), especially those with near-infrared (NIR) absorbers. In this work, two NIR boron dipyrromethene (BODIPY) molecules are characterized for application in planar (PHJ) bulk (BHJ) heterojunction OSCs. When H atoms substituted by F on peripheral phenyl rings molecules, molecular...
Measuring volatility in financial markets is a primary challenge the theory and practice of risk management essential when developing investment strategies. Although vast literature on topic describes many different models, two nonparametric measurements have emerged received wide use over past decade: realized absolute return volatility. The former strongly favored sector latter by econophysicists. We examine memory clustering features these methods find that both enable strong predictions....
Recently, N-heterocyclic carbenes (NHCs) are explored as anchor groups to bind organic ligands colloidal gold (i.e. nanoparticles, Au NPs), yet these efforts confined non-conjugated so far-that is, focused solely on exploiting the stability aspect. Using NHCs link NPs and electronically active components, for example, conjugated polymers (CPs), will allow capitalizing both well inherent conductivity of NHC anchors. Here, we report three types Br-NHC-Au-X (X=Cl, Br) complexes, which, when...
Abstract Smart responsive materials that can alter their function in response to environmental changes are attractive for potential applications intelligent devices and products. Herein, a smart material exhibits reversible multiple properties upon variations humidity or temperature is created.

This paper presents a new monitoring method for multimode processes based on subspace decomposition. In the proposed method, influence of quality variables and information are considered in modeling, which is crucially important to ensure industrial production safety stabilization. Process data decomposed into global common local specific performed each simplify model structure. Two experiments: penicillin fermentation practical foods processes, have been used demonstrate excellent...
One-dimensional (1D) fibers have been widely used in composites reinforcement for microwave attenuation due to their outstanding mechanical and electromagnetic properties, especially the axial direction. However, precise control of fiber alignment a polymer matrix remains challenge. In this work, we successfully demonstrated well-controlled silicon carbide nanowires (SiCNW) silicone by using direct ink writing (DIW)-based 3D printing. It is proven that printed multilayer material with could...

Both molecules planar characterized as intense deep‐red/NIR emitters emission bands tunable by solution concentration. Their red‐shifted to λ =730 760 nm vacuum‐deposited films.
Matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS) and the corresponding visualizing technique MALDI MS imaging (MSI) are potent widely used analytical methods in medical pathological research. In recent years, investigation of low-molecular-weight compounds (LMWCs) such as metabolites has moved increasingly into focus. techniques require a matrix system, small organic matrices (SOMs) commonly used. While SOMs offer multiple advantages, broad analyte scopes high...

With high thermal stability, can be purified sublimation used prepare vacuum‐deposited thin films. This research extends family...
Abstract Polytriarylamines (PTAAs) are amorphous polymers that can be reversibly oxidized to generate stable radical cations. Despite exhibiting a low charge carrier mobility, PTAAs widely used as hole‐transporting layers in perovskite solar cells due their excellent stability under ambient conditions. The highest occupied molecular orbital (HOMO) energy levels of PTAA generally the range −5.1 −5.2 eV, and therefore slightly too high for an optimal alignment with perovskites. Most linear...
