Dynamic covalent bonds in a polymer network lead to plasticity, reshapability, and potential recyclability at elevated temperatures combination with solvent-resistance better dimensional stability lower temperatures. Here we report simple one-step procedure for the catalyst-free preparation intramolecularly catalyzed stress-relaxation of dynamic polyester networks. The is based on coupling branched OH-end functional polyesters (functionality ≥ 3) by pyromellitic dianhydride (PMDA) or...
Dynamic covalent networks are a class of polymeric materials that combine the merits classical thermosets and thermoplastics, in terms mechanical properties reprocessability, one material. Various dynamic chemistries have thus been implemented with recent interests shifting toward would allow rearrangements network topology without aid external catalysts. Here we introduce transesterification phosphate triesters as new chemistry networks. A simple one-step synthetic strategy has utilized to...
Machine learning algorithms are crucial for crop identification and mapping. However, many works only focus on the results of these algorithms, but pay less attention to their classification performance mechanism. In this paper, based Google Earth Engine (GEE), Sentinel-2 10 m resolution images during a specific phenological period winter wheat were obtained. Then, support vector machine (SVM), random forest (RF), regression tree (CART) employed identify map in large-scale area. The...
Abstract Ship emission impacts ambient air quality, especially in coastal regions, by emitting pollutants such as fine particles, nitrogen oxides (NO x ), and sulfur dioxide (SO 2 yet its contributions to volatile organic compounds (VOCs) the formation of secondary aerosol (SOA) ozone (O 3 ) are much less constrained with challenge distinguish ship from land diesel emission. In this study, we conducted a 1‐year online measurement VOCs 1‐hr resolution at site south China's Pearl River Delta...
Eutrophication and the predicted limited future availability of rock phosphate has triggered increased development phosphorus (P) recovery technologies, however, for remote regions, solutions are still limited. Here, we report on a novel pilot-scale technology (FILTRAFLOTM-P reactor) to recover (PO43-) from wastewater effluent through filtration/adsorption process in rural setting. This unit employs enhanced gravitational filtration adsorption media (here, KOH deacetylated crab carapace...
The diamide–imide equilibrium was successfully exploited for the synthesis of dynamic covalent polymer networks in which a dissociative bond exchange mechanism leads to high processibility at temperatures above ≈110 °C. Dynamic bridge gap between thermosets and thermoplastic polymers. At operating temperature, when network is fixed, are elastic solids, while temperatures, chemical reactions turn into processible viscoelastic material. Upon heating network, viscosity may also decrease due...
Monitoring lightning and its location is important for understanding thunderstorm activity revealing discharge mechanisms. This often realized based on very low-frequency/low-frequency (VLF/LF) signals, high-frequency (VHF) optical radiation signals generated during the process. The development of monitoring technology worldwide has largely evolved from a single station to multiple stations, return strokes (RSs) cloud-to-ground (CG) flashes total flashes, channels, ground-based observations...
The substrate impurities scattering will lead to unstable temperature-sensitive behavior and poor linearity in graphene temperature sensors. And this can be weakened by suspending the structure. Herein, we report a sensing structure, with suspended membranes fabricated on cavity non-cavity SiO2/Si substrate, using monolayer, few-layer, multilayer graphene. results show that sensor provides direct electrical readout from resistance transduction nano piezoresistive effect structure weaken...
Bond exchange via neighboring group-assisted reactions in dynamic covalent networks results efficient mechanical relaxation. In Nature, the high reactivity of RNA toward nucleophilic substitution is largely attributed to formation a cyclic phosphate ester intermediate group participation. We took inspiration from develop network based on β-hydroxyl-mediated transesterifications hydroxyethyl triesters. A simple one-step synthetic strategy provided containing triesters with pendant group. 31P...
In dynamic polyamide networks, 1,2,4,5-benzene tetraamide (B4A) units act simultaneously as a covalent cross-linker and supramolecular stacking motif. This results in materials with rubbery plateau modulus that is about 20 times higher than of corresponding reference network which the interaction suppressed. branched polyamides same B4A motif, hydrogen bonding lead to strong reversible whereas nonstacking linker viscous liquid under conditions. Wide-angle X-ray scattering...
Abstract t ‐Butyl‐oxycarbonylated diamines (“di‐Boc‐carbamates”) are investigated as dicarbamate monomers for diamine/dicarbamate polymerizations. Polyureas (PUs) and polyurethanes (PURs) with high molecular weights prepared from stoichiometric polymerizations of or diols N‐N′ ‐di‐ ‐butyl‐oxycarbonyl isophorone diamine (DiBoc‐IPDC) using KO ‐Bu a catalyst, while gelation is observed when an excess DiBoc‐IPDC used respect to the diols.

The flexoelectricity polarization of nanoscale dimensions has a natural advantage in realizing highly sensitive pressure sensors two-dimensional. Further, as typical Two-dimensional material materials, graphene was often combined for sensors. As the result high dielectric constant, PZT nanofilm could produce large surface potential when subjected to external weak force. Then fermi level on film can be regulated by electric field, which signals sensor. We report novel graphene-based sensor...
