Rapid synthesis of [Au25(Cys)18] nanoclusters via carbon monoxide in microfluidic liquid-liquid segmented flow system and their antimicrobial performance

Huang, He; Hwang, Gi Byoung; Wu, Gaowei; Karu, Kersti; Du Toit, Hendrik; Wu, Han; Callison, June; Parkin, Ivan P.; Gavriilidis, Asterios

Atomically precise thiolate-gold nanoclusters with well-defined structures attract attention for use in various applications. However, most of the recently reported synthetic methods rely on prolonged synthesis times (a few hours to days) in order to produce high purity materials with a single cluster size. Such extended synthesis times make these…

Bacteria-Resistant, Transparent, Free-Standing Films Prepared from Complex Coacervates

Kurtz, Irene S.; Sui, Shuo; Hao, Xi; Huang, Mengfei; Perry, Sarah L.; Schiffman, Jessica D.

We report the fabrication, properties, and bacteria-resistance of polyelectrolyte complex (PEC) coatings and free-standing films. Poly(4-styrenesulfonic acid), poly(diallyldimethylammonium chloride), and salt were spin-coated into PEC films. After thermal annealing in a humid environment, highly transparent, mechanically strong, and chemically robust films were formed. Notably, we demonstrate…

Two-Step Chemical Transformation of Polystyrene-block-poly(solketal acrylate) Copolymers for Increasing ?

Yu, Duk Man; Smith, Darren M.; Kim, Hyeyoung; Rzayev, Javid; Russell, Thomas P.

We investigated the two-step chemical transformation of a series of symmetric poly(styrene-b-solketal acrylate) (PS-b-PSA) copolymers with varying molecular weights from 1900 to 27?300 g/mol (13 ? N ? 194) synthesized by sequential atom transfer radical polymerization. Through acid-catalyzed hydrolysis, the PSA block is converted into poly(glycerol acrylate) (PGA), which subsequently…

Multi-scale modelling approach to homogenise the mechanical properties of polymeric closed-cell bead foams

Gebhart, Thomas M. J.; Jehnichen, Dieter; Koschichow, Roman; Müller, Michael; Göbel, Michael; Geske, Vinzenz; Stegelmann, Michael; Gude, Maik

The complex mechanical deformation behaviour of closed-cell foams is governed by morphological and physical properties such as cell structure and crystallinity. In this study, the micro-, meso- and macroscopic scale of commercially available bead foam was analysed. Statistical distribution of the cell structure including cell size, wall thickness and shape…

Dental Resin Monomer Enables Unique NbO2/Carbon Lithium-Ion Battery Negative Electrode with Exceptional Performance

Ji, Qing; Gao, Xiangwen; Zhang, Qiuju; Jin, Liyu; Wang, Da; Xia, Yonggao; Yin, Shanshan; Xia, Senlin; Hohn, Nuri; Zuo, Xiuxia; Wang, Xiaoyan; Xie, Shuang; Xu, Zhuijun; Ma, Liujia; Chen, Liang; Chen, George Z.; Zhu, Jin; Hu, Binjie; Müller?Buschbaum, Peter; Bruce, Peter G.; Cheng, Ya-Jun

Niobium dioxide (NbO2) features a high theoretical capacity and an outstanding electron conductivity, which makes it a promising alternative to the commercial graphite negative electrode. However, studies on NbO2 based lithium-ion battery negative electrodes have been rarely reported. In the present work, NbO2 nanoparticles homogeneously embedded in a carbon matrix…

Tuning Mechanical Properties of Biobased Polymers by Supramolecular Chain Entanglement

Lamm, Meghan E.; Song, Lingzhi; Wang, Zhongkai; Rahman, Md Anisur; Lamm, Benjamin; Fu, Lin; Tang, Chuanbing

A variety of biobased polymers have been derived from diverse natural resources. However, the mechanical properties of some of these polymers are inferior due to low chain entanglement. We report a facile strategy termed “supramolecular chain entanglement”, which utilizes supramolecular interactions to create physical cross-linking and entanglements for polymers with…

Investigation of the internal structure of thermoresponsive diblock poly(2-methyl-2-oxazoline)-b-poly[N-(2,2-difluoroethyl)acrylamide] copolymer nanoparticles

Babuka, David; Kolouchova, Kristyna; Hruby, Martin; Groborz, Ondrej; Tosner, Zdenek; Zhigunov, Alexander; Stepanek, Petr

The poly(2-methyl-2-oxazoline)-b-poly self-assembled nanoparticles show great potential in biological applications as, e.g., 19F MRI tumour diagnostic agents. As such their internal structure needs to be thoroughly investigated while the results also help to understand temperature-dependent self-assembly behaviour of copolymers comprised of the hydrophilic and…

Single-step preparation of mono-dispersed sulfur nanoparticles for detention of copper

Shevchenko, Natalia; Steinhart, Milos; Tomšík, Elena

Application of sulfur nanoparticles results from biocompatibility, biodegradability, and non-toxicity of the shell that covers sulfur nanoparticles. However, to prepare uniform sulfur nanoparticles still remains a challenge; particularly in aqueous medium when the size of sulfur nanoparticles is not more than 20 nm. In the current work, the detailed investigation…

Tunable Fluorophobic Effect Determines Nanoparticle Dispersion in Homopolymers and Block Polymers

Marsh, Zachary M.; Blom, Douglas A.; Stefik, Morgan

The controlled placement of nanoparticles (NPs) within homopolymers and block polymers is of broad interest for functional nanomaterials. This manuscript focuses on small molecule-stabilized NPs that bring a large fraction of functionality. For such NP mixtures with block polymers, the overwhelming focus to date has been the use of attractive…

Fragmentation of 1,2-Polybutadiene-block-Poly(ethylene oxide) Micelles in Imidazolium-Based Ionic Liquids

Early, Julia T.; Lodge, Timothy P.

The effect of solvent selectivity on the fragmentation kinetics of spherical micelles formed by a 1,2-polybutadiene-block-poly(ethylene oxide) “BO” copolymer in five 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide-based ionic liquids (ILs), (, where n = methyl, ethyl, butyl, hexyl, and octyl) was investigated by temperature-jump dynamic light scattering (T-jump DLS),…
