- Core–Shell Composite Synthesized through In Situ Polymerization in Emulsion with High Electrical Conductivity Sensitive to Humidity
Lipei Yue, Weidong Li, Yingjie Cao and Yongping Bai
Version of Record online: 27 MAR 2017 | DOI: 10.1002/ppsc.201600423
A core–shell composite is synthesized through in situ polymerization in emulsion with high electrical conductivity sensitive to humidity. Each composite consists of a graphene oxide core and a poly(methyl methacrylate/butyl acrylate) shell. The latex can be applied as an environmentally healthy conductive adhesive and lucid conductive film.
- One-Pot Purification and Iodination of Waste Kish Graphite into High-Quality Electrocatalyst
In-Yup Jeon, Sun-Hee Shin, Sun-Min Jung, Hyun-Jung Choi, Jiantie Xu and Jong-Beom Baek
Version of Record online: 27 MAR 2017 | DOI: 10.1002/ppsc.201600426
Using mechanochemical ball-milling, waste Kish graphite (Kish-G) is simply converted into high-quality electrocatalyst for oxygen reduction reaction in alkaline media. Ball-milling Kish-G in the presence of iodine simultaneously purifies and functionalizes Kish-G into iodinated Kish-G (I-Kish-G) with low content of impurities, high iodine content, high degree of crystallinity, and high specific surface area.
- Mesoporous Silica Promoted Deposition of Bioinspired Polydopamine onto Contrast Agent: A Universal Strategy to Achieve Both Biocompatibility and Multiple Scale Molecular Imaging
Yu-Wei Chen, Yung-Kang Peng, Shang-Wei Chou, Yu-Jui Tseng, Pei-Chun Wu, Shin-Kung Wang, Yi-Wei Lee, Jing-Jong Shyue, Jong-Kai Hsiao, Tzu-Ming Liu and Pi-Tai Chou
Version of Record online: 27 MAR 2017 | DOI: 10.1002/ppsc.201600415
Mesoporous silica with high density of surface OH concentration is found to facilitate heterogeneous nucleation of dopamine and suppress dopamine random self-polymerization in water. Accordingly, a four-in-one (magnetic resonance T1 & T2, computed tomography, multiphoton luminescence) imaging nanocomposite was firstly synthesized and demonstrated its power in both in vitro and in vivo testing.
- Defluorination of Fluorographene Oxide via Solvent Interactions
Kiran Kumar Tadi, Santosh Kumar Bikkarolla, Kapil Bhorkar, Shubhadeep Pal, Narayan Kunchur, Indulekha N., Sruthi Radhakrishnan, Ravi K. Biroju and Tharangattu N. Narayanan
Version of Record online: 7 MAR 2017 | DOI: 10.1002/ppsc.201600346
Here, the site specific interactions of polar solvents (such as THF) with Fluorographene Oxide (FGO) leading to its defluorination are demonstrated. DFT studies are conducted to understand the interactions of various solvents with graphene and FGO, and defluorination of FGO during its interaction with THF is demonstrated experimentally, as shown in the figure by the change in its color in THF to black.
- Intracellular Breakable and Ultrasound-Responsive Hybrid Microsized Containers for Selective Drug Release into Cancerous Cells
Alexander S. Timin, Albert R. Muslimov, Kirill V. Lepik, Maria V. Okilova, Nikolai Y. Tcvetkov, Alena I. Shakirova, Boris V. Afanasyev, Dmitry A. Gorin and Gleb B. Sukhorukov
Version of Record online: 6 MAR 2017 | DOI: 10.1002/ppsc.201600417
Comparative analysis of stimuli-responsive drug release into mesenchymal stem cells as an example of healthy cells and cancerous cells is performed using a novel type of dual-responsive microsized containers made of assembled polyelectrolytes followed up by in situ sol-gel coating.
