Scalable preparation of alternating block copolymer particles with inverse bicontinuous mesophases

Lv, Fei; An, Zesheng; Wu, Peiyi

Block copolymer particles with controlled morphologies play a vital role in materials science and nanotechnology. Here the authors show a scalable preparation of amphiphilic alternating block polymer particles with inverse bicontinuous mesophases via polymerization-induced…

Redox-Activatable ATP-Depleting Micelles with Dual Modulation Characteristics for Multidrug-Resistant Cancer Therapy

Wang, Hebin; Li, Yang; Zhang, Miaozun; Wu, Di; Shen, Youqing; Tang, Guping; Ping, Yuan

A fast adenosine triphosphate (ATP)-depleting micellar system that is activated by intracellular redox for the codelivery of anticancer drug paclitaxel (PTX) and small interference RNA (siRNA) targeting polo-like kinase1 (PLK1) is developed to address the key challenges of multidrug-resistant (MDR) cancer therapy. The ATP-depleting micelle is self-assembled from a redox-responsive…

Residual Silver Remarkably Enhances Electrocatalytic Activity and Durability of Dealloyed Gold Nanosponge Particles

Li, Guangfang Grace; Lin, Ye; Wang, Hui

Percolation dealloying of multimetallic alloys entangles the selective dissolution of the less-noble elements with nanoscale restructuring of the more-noble components, resulting in the formation of spongelike, nanoporous architectures with a unique set of structural characteristics highly desirable for heterogeneous catalysis. Although the dealloyed nanoporous materials are compositionally…

Multifaceted Gold–Palladium Bimetallic Nanorods and Their Geometric, Compositional, and Catalytic Tunabilities

Sun, Lichao; Zhang, Qingfeng; Li, Guangfang Grace; Villarreal, Esteban; Fu, Xiaoqi; Wang, Hui

Kinetically controlled, seed-mediated co-reduction provides a robust and versatile synthetic approach to multimetallic nanoparticles with precisely controlled geometries and compositions. Here, we demonstrate that single-crystalline cylindrical Au nanorods selectively transform into a series of structurally distinct Au@Au–Pd alloy core–shell bimetallic nanorods with exotic multifaceted geometries…

Overcoming the Interfacial Lattice Mismatch: Geometry Control of Gold–Nickel Bimetallic Heteronanostructures

Li, Guangfang Grace; Blom, Douglas A.; Pandey, Shubham; Koch, Robert J.; Misture, Scott T.; Phillpot, Simon R.; Wang, Hui

Seed-mediated heteroepitaxial growth provides a versatile synthetic approach to a diverse set of geometrically distinct bimetallic heteronanostructures. In bimetallic nanocrystal systems, interfacial heteroepitaxial growth typically occurs between structurally similar metals with lattice mismatch below 5%, whereas controlled epitaxial growth of bimetallic nanocrystals comprising metals with…

Epsilon-Fe2O3 Nanocrystals inside Mesoporous Silicas with Tailored Morphologies of Rod, Platelet and Donut

Li, Jheng-Guang; Fornasieri, Giulia; Bleuzen, Anne; Gich, Martí; Impéror‐Clerc, Marianne

The ϵ-Fe2O3 polymorph of iron oxide, which has outstanding physical properties, is successfully stabilized inside mesoporous silica particles with tailored shapes. Using mesoporous silica particles with three different morphologies of rod, platelet and donut, we obtain ϵ-Fe2O3/mesoporous silica nanocomposites. Iron oxide is loaded inside the porosity using a two steps…
