Core–Shell Gold Nanoparticle-Star Copolymer Composites with Gradient Transfer and Transport Properties: Toward Electro-Optical Sensors and Catalysis

Autor: Rigoberto C. Advincula, Peng-Fei Cao, Lihan Rong, Xiang Cheng

Publikováno v: ACS Applied Nano Materials. 4:1394-1400

A series of hybrid core–shell nanomaterials was prepared by solvent phase transfer methods with gold (Au) nanoparticles (NPs) as a core and star copolymers (h-PEI-b-PCL-Cbz) as a shell—consisting o...

4D Printing via an Unconventional Fused Deposition Modeling Route to High-Performance Thermosets

Autor: Jingbo Ren, Lihan Rong, Peng-Fei Cao, Rigoberto C. Advincula, Qiyi Chen, Lu Han

Publikováno v: ACS Applied Materials & Interfaces. 12:50052-50060

An unprecedented four-dimensional (4D) printing process allowing high-performance and shape memory thermoset to be printed, for the first time, by fused deposition modeling (FDM) with isotropic properties has been achieved. Bisphenol A-based epoxy an

Biocompatibility of a novel heat-treated and ceramic-coated magnesium alloy (Mg–1.2Zn–0.5Ca–0.5Mn) for resorbable skeletal fixation devices

Autor: Patrick Smith, Alan A. Luo, Mohammad Elahinia, Tim McManus, David Dean, Taylor MacDonald, Lihan Rong, Jan A Lammel Lindemann, Rigoberto C. Advincula, Agnieszka Chmielewska, Hamdy Ibrahim, Wojciech Swieszkowski

Publikováno v: MRS Communications. 10:467-474

Our recent exploration into the use of biodegradable metals and surface treatments resulting in sufficient strength for skeletal reconstruction applications has led to the need to test these devices’ cytotoxicity. More specifically, our group has d

Highly thermally stable copolymers of epoxy and trifunctional polybenzoxazine

Autor: Lucio R. Souza, Lihan Rong, Xiang Cheng, Eugene B. Caldona, Rigoberto C. Advincula, José Roberto Moraes d'Almeida

Publikováno v: Materials Today Communications. 30:102988

In this work, we report the copolymerization of a triamine-based benzoxazine and a commercial difunctional epoxy resin, and investigate their synergistic effect on improved thermal properties using differential scanning calorimetry (DSC) and thermogr
