Angewandte Chemie, Accepted Article.Metallic catalysts with nanopores are advantageous on improving both activity and selectivity, while the reason behind that remains unclear all along. In this work, porous Zn nanoparticles (P‐Zn) were adopted as a model catalyst to investigate the catalytic behavior of metallic nanopores. In‐situ X‐ray absorption … [Weiterlesen...] Infos zum Plugin Electroreduction of Carbon Dioxide in Metallic Nanopores through a Pincer Mechanism
Evaluation and design methods for high‐efficiency charring composite under complex coupling mechanisms in both material and boundary layer
Journal of Applied Polymer Science, EarlyView.By taking the coupling ablative mechanism into consideration, a multi‐field coupling model with key influencing factor to evaluate material responses and chemical responses in boundary layer is developed and numerically solved by our coupling calculation strategy. By designing the distribution of key factor along material … [Weiterlesen...] Infos zum Plugin Evaluation and design methods for high‐efficiency charring composite under complex coupling mechanisms in both material and boundary layer
Synthesis and properties of syndiotactic 1,2‐polybutadiene catalyzed by iron catalyst with phosphate as additive
Journal of Applied Polymer Science, EarlyView. Abstract 1,2 Syndiotactic polymerization of butadiene is accessible by iron catalysts prepared from commercially available iron sources, trialkylaluminum with additional phosphate as additive. The catalyst formation is quite robust in terms of handling and stability under polymerization conditions. Activity equal to 115 kg … [Weiterlesen...] Infos zum Plugin Synthesis and properties of syndiotactic 1,2‐polybutadiene catalyzed by iron catalyst with phosphate as additive
Antibacterial Polyelectrolytic chitosan derivatives conjugated natural rubber latex films with minimized bacterial adhesion
Journal of Applied Polymer Science, EarlyView. Abstract Water soluble polyelectrolytic derivatives of chitosan (CDs) with carboxyl (COO−) and quaternary ammonium (NH4+) groups were synthesized and characterized by NMR, FT‐IR, TGA and zeta potential analyses; while degree of substitution was determined by potentiometric titrations. Both CDs in the … [Weiterlesen...] Infos zum Plugin Antibacterial Polyelectrolytic chitosan derivatives conjugated natural rubber latex films with minimized bacterial adhesion
Biomass/polyhedral oligomeric silsesquioxane nanocomposites: Advances in preparation strategies and performances
Journal of Applied Polymer Science, EarlyView. Abstract Polyhedral oligomeric silsesquioxane (POSS) as an organic–inorganic hybrid at a molecular level, has excellent mechanical properties, thermodynamic properties, dielectric properties and so on. In recent decades, POSS has been extensively used in modification of various polymers to prepare nanocomposites with … [Weiterlesen...] Infos zum Plugin Biomass/polyhedral oligomeric silsesquioxane nanocomposites: Advances in preparation strategies and performances
