A Facile Synthesis of Pure O2PtF6

28.08.2015 | Stefan S. Rudel, Florian Kraus, Zeitschrift für anorganische und allgemeine Chemie, 2015

Abstract A new and facile synthesis of O2PtF6 is reported without the demanding synthesis of PtF6 or the use of high pressure fluorination in the presence of oxygen. The O2PtF6 is obtained in form of single crystals by direct Klemm‐type fluorination of commercially available PtO2·xH2O in a ...

A Highly Stable and Magnetically Recyclable Nanocatalyst System: Mesoporous Silica Spheres Embedded with FeCo/Graphitic Shell Magnetic Nanoparticles and Pt Nanocatalysts

28.08.2015 | Da Jeong Kim, Yan Li, Yun Jin Kim, Nam Hwi Hur, Won Seok Seo, Chemistry - An Asian Journal, 2015

We have developed a highly stable and magnetically recyclable nanocatalyst system for alkene hydrogenation. The materials are composed of mesoporous silica spheres (MSS) embedded with FeCo/graphitic shell (FeCo/GC) magnetic nanoparticles and Pt nanocatalysts (Pt‐FeCo/GC@MSS). The Pt‐FeCo/GC@MSS ...

Thermal Stability of Sulfonated Poly(Ether Ether Ketone) Films: on the Role of Protodesulfonation

27.08.2015 | Beata T. Koziara, Emiel J. Kappert, Wojciech Ogieglo, Kitty Nijmeijer, Mark A. Hempenius, Nieck E. Benes, Macromolecular Materials and Engineering, 2015

Thin film and bulk, sulfonated poly(ether ether ketone) (SPEEK) have been subjected to a thermal treatment at 160–250 °C for up to 15 h. Exposing the films to 160 °C already causes partial desulfonation, and heating to temperatures exceeding 200 °C results in increased conjugation in the ...

Recovery of Flavonoids from Walnuts De‐Pellicle Wastewater with Macroporous Resins and Evaluation of Antioxidant Activities In Vitro

27.08.2015 | Yaxin Zhu, Hao Song, Xu Zhang, Chaoyin Chen, Shenglan Zhao, Feng Ge, Diqiu Liu, Journal of Food Process Engineering, 2015

Abstract Walnut de‐pellicle wastewater is rich in polyphenols and flavonoids that are significant to resource and environment. Enrichment and purification of flavonoids from walnut de‐pellicle wastewater were investigated by five macroporous resins. As static tests shown, AB‐8 resin was the ...

Nano “Chocolate Waffle” for near‐IR Responsive Drug Releasing System

27.08.2015 | Junseok Lee, Hansoo Park, Won Jong Kim, Small, 2015

A majority of the photo‐responsive drug‐delivery systems that are currently being studied require a complicated synthesis method. Here, we prepare a near‐infrared responsive, photothermally controllable, drug‐delivery carrier by a simple mixing and extraction process without the incorporation of ...
