Heterogeneous catalysis performs on specific sites of a catalyst surface even if many catalysts during could not be identified readily. Design by managing catalytic an atomic scale is significant for tuning performance and offering high activity selectivity at relatively low temperature. Here, we report synergy effect two sets single-atom (Ni1 Ru1) anchored the CeO2 nanorod, Ce0.95Ni0.025Ru0.025O2. The this catalyst, Ce0.95Ni0.025Ru0.025O2, consists which are highly active reforming CH4...
Size control: Sterically stabilized methacrylic nanolatexes are readily prepared by aqueous dispersion polymerization using RAFT reactions (see scheme; CTA=chain transfer agent). Varying the length of poly(HPMA) chains allows precise size control nanolatex particles. Detailed facts importance to specialist readers published as ”Supporting Information”. Such documents peer-reviewed, but not copy-edited or typeset. They made available submitted authors. Please note: The publisher is...
Zwitterionic polymers and poly(ethylene glycol) (PEG) have been reported as promising nonfouling materials, strong surface hydration has proposed a significant contributor to the mechanism. Better understanding of similarity difference between these two types materials in terms protein interaction will benefit design new effective materials. In this study, sum frequency generation (SFG) vibrational spectroscopy was applied for situ real-time assessment sulfobetaine methacrylate (SBMA)...
Abstract Catalytic transformation of CH 4 under a mild condition is significant for efficient utilization shale gas the circumstance switching raw materials chemical industries to gas. Here, we report acetic acid and methanol through coupling , CO O 2 on single-site Rh 1 5 anchored in microporous aluminosilicates solution at ≤150 °C. The activity these singly dispersed precious metal sites production organic oxygenates can reach about 0.10 molecules site per second 150 °C with selectivity...
Zwitterionic nanogels of varying stiffness were prepared by tuning their cross-linking densities and reactant contents. In vivo studies these show that softer pass through physiological barriers, especially the splenic filtration, more easily than stiffer counterparts, consequently leading to longer circulation half-life lower accumulation. Results from this work emphasize role in designing long-circulating nanoparticles.
Abstract Direct conversion of methane to chemical feedstocks such as methanol under mild conditions is a challenging but ideal solution for utilization methane. Pd 1 O 4 single‐sites anchored on the internal surface micropores microporous silicate exhibit high selectivity and activity in transforming CH 3 OH at 50–95 °C aqueous phase through partial oxidation with H 2 . The production remains 86.4 %, while 95 about 2.78 molecules per site second when 2.0 wt % CuO used co‐catalyst @ZSM‐5....
Hot spots: Thermally responsive AB diblock copolymers that self-assemble into vesicles at higher temperatures were prepared (see picture). These can be cross-linked by adding an oppositely charged polyelectrolyte.

Two double-hydrophilic block copolymers, each comprising a nonionic and an anionic pendent aromatic sulfonate groups, were used as additives to modify the crystallization of CaCO3. Marked morphological changes in CaCO3 particles observed depending on reaction conditions used. A poly(ethylene oxide)-b-poly(sodium 4-styrenesulfonate) diblock copolymer was particularly versatile effecting change calcite particles, continuous structural transition product from polycrystalline mesocrystal single...
Highly branched poly(2-hydroxypropyl methacrylate) has been prepared by atom transfer radical polymerization (ATRP) in methanol at 20 °C using a disulfide-based dimethacrylate (DSDMA) branching agent. The mean degree of the primary chains was fixed 50; since ATRP reasonably good living character, molecular weight distribution these is relatively narrow, which allows significantly better control than conventional polymerization. Varying proportion DSDMA produced series soluble polymers,...
A poly(ethylene oxide) (PEO)-based macromolecular chain transfer agent (macro-CTA) was employed to demonstrate the controlled polymerization of N,N-dimethylacrylamide (DMA) in anhydrous 1,4-dioxane at 70 °C using reversible addition−fragmentation polymerization. This macro-CTA then used mediate statistical copolymerization DMA and reactive monomer N-acryloxysuccinimide (NAS), forming a diblock copolymer PEO-b-(DMA-s-NAS). Subsequent extension with N-isopropylacrylamide (NIPAM) yielded...
Compared to homogeneous catalysis, heterogeneous catalysis allows for ready separation of products from the catalyst and thus reuse catalyst. C-C coupling is typically performed on a molecular which mixed with reactants in liquid phase during catalysis. This mixing at level same makes extremely challenging costly. Here we demonstrated that TiO2-based nanoparticle anchoring singly dispersed Pd atoms (Pd1/TiO2) selective highly active more than 10 Sonogashira reactions (R≡CH + R'X → R≡R'; X =...
Zwitterionic materials have shown their excellent performance in many biological and chemical applications. possess moieties that own both cationic anionic groups. The associations among zwitterionic through electrostatic interactions play an important role properties of materials. However, the relationship between molecular structures are still not well understood. This work compared thermal- salt-responsive behaviors sulfobetaine carboxybetaine polymers by examining rheological as a...
Surface hydration has been proposed as the key nonfouling mechanism of zwitterionic materials. Because these materials have various chemical structures and will be used in complex environments, situ probing their surfaces different aqueous environments is crucial to understanding surface properties. In this work, three polymer brushes solutions with salts or varied pH were probed using sum frequency generation (SFG) vibrational spectroscopy. The SFG spectra indicate ordering water strong...
