Particle mobility and macroscopic magnetorheological effects for polyurethane magnetic elastomers
Particle mobility and macroscopic magnetorheological effects for polyurethane magnetic elastomers The relationship between the particle mobility and magnetorheological effect was investigated for polyurethane magnetic elastomers containing carbonyl iron particles with various cross-linking densities or plasticizer concentrations. The storage modulus at 0 mT increased and the on-field modulus at 500 mT decreased with the cross-linking density.
The effect of Dictyophora indusiata, oats, and Polygonatum kingianum on the physicochemical properties and in vitro digestion of pizza crust
A high glycemic index diet can lead to elevated blood glucose levels and chronic diseases. In this study, Dictyophora indusiata powder, oats powder, and Polygonatum kingianum powder were substituted for some wheat flour to make pizza crust. The aim was to investigate the effects of the three powders on the chemical composition, physical quality, antioxidant properties, in vitro digestibility of starch, and sensory characteristics of pizza crust.
Physics-Guided Residual Learning for Probabilistic Power Flow Analysis
Renewable power generation technology has been developed rapidly due to its great advantage in economic savings and environmental friendliness [1]. However, compared with conventional generation, renewable generation (e.g., solar and wind power) is highly dependent on weather conditions, such as ambient temperature, solar irradiance, relative humidity, wind speed, etc [2].
Influencing Factors on Li‐ion Conductivity and Interfacial Stability of Solid Polymer Electrolytes, Exampled by Polycarbonates, Polyoxalates and Polymalonates
Graphical Abstract Three families of ester-based solid polymer electrolytes of polycarbonate, polyoxalate and polymalonate were prepared and investigated on their Li+-conductivity and antioxidation ability, demonstrating the performances of solid polymer electrolytes are affected by the coordinating capability with Li+, molecular asymmetry and existing modes of elemental F.
Ligand Engineering in Nickel Phthalocyanine to Boost the Electrocatalytic Reduction of CO2
Abstract Designing and synthesizing efficient molecular catalysts may unlock the great challenge of controlling the CO2 reduction reaction (CO2RR) with molecular precision. Nickel phthalocyanine (NiPc) appears as a promising candidate for this task due to its adjustable Ni active-site. However, the pristine NiPc suffers from poor activity and stability for CO2RR owing to the poor CO2 adsorption and activation at the bare Ni site.

Iron phthalocyanine with coordination induced electronic localization to boost oxygen reduction reaction
Abstract Iron phthalocyanine (FePc) is a promising non-precious catalyst for the oxygen reduction reaction (ORR). Unfortunately, FePc with plane-symmetric FeN4 site usually exhibits an unsatisfactory ORR activity due to its poor O2 adsorption and activation. Here, we report an axial Fe–O coordination induced electronic localization strategy to improve its O2 adsorption, activation and thus the ORR performance.
