Tuning High‐Temperature Wetting Behavior of Metal toward Ultrafine Nanoparticles

18.01.2018 | Yubing Zhou, Bharath Natarajan, Yanchen Fan, Hua Xie, Chunpeng Yang, Shaomao Xu, Yonggang Yao, Feng Jiang, Qianfan Z ..., Angewandte Chemie, 2018

The interaction between the metal nanoparticles and their substrate plays a critical role in determining the particle morphology, distribution, and properties. Here we present the pronounced impact of a thin oxide coating to the dispersion of metal nanoparticles on a carbon matrix. We employ ...


Two Nickel(II) Coordination Polymers Based on Tri(p‐carboxyphenyl) phosphane Oxide with Highly Selectively and Sensitively Detection of Acetone

15.01.2018 | Kegong Fang, liangqin Huo, Lingling Gao, Fuqiang An, Jianfeng Gao, Liming Fan, tuoping hu, Zeitschrift für anorganische und allgemeine Chemie, 2018

Abstract. Two nickel (II) coordination polymers, namely, {[Ni1/2(TPO)1/3(bib)1/2(H2O)]*H2O}n (1), and [Ni(HTPO)(bpy)(H2O)2]n (2), have been assembled from tripodal ligand of tripodal tri(p‐carboxyphenyl) phosphane oxide (H3TPO) and two N‐donors (bib = 1,4‐bis(imidazolyl)benzene, and bpy = ...


High Temperature and High Energy Density Dipolar Glass Polymers based on Sulfonylated Poly(2,6‐dimethyl‐1,4‐phenylene oxide)

21.12.2017 | Zhongbo Zhang, David H. Wang, Morton H. Litt, Loon-Seng Tan, Lei Zhu, Angewandte Chemie, 2017

A new class of high temperature dipolar polymer, sulfonylated poly(2,6‐dimethyl‐1,4‐phenylene oxide) (SO2‐PPO), was synthesized via post‐polymer functionalization. Due to efficient rotation of highly polar methylsulfonyl side groups below the glass transition temperature (Tg ~ 220 °C), enhanced ...


All‐in‐One Cellulose Nanocrystals for 3D Printing of Nanocomposite Hydrogels

21.12.2017 | Hansjörg Grützmacher, Jieping Wang, Annalisa Chiappone, Ignazio Roppolo, Feng Shao, Erika Fantino, Massimo Lorusso, ..., Angewandte Chemie, 2017

Cellulose nanocrystals (CNCs) with >2000 photoactive groups can act as highly efficient initiators for radical polymerizations, cross‐linkers, as well as covalently embedded nanofillers for nanocomposite hydrogels. This is achieved by a simple and reliable method for surface modification of CNCs ...


A Breathing ATRP: Fully Oxygen Tolerant Polymerization Inspired by Aerobic Respiration of Cells

14.12.2017 | Krzysztof Matyjaszewski, Liye Fu Fu, Alan Russell Russell, Alan E. E. Enciso, Angewandte Chemie, 2017

The first well‐controlled aqueous atom transfer radical polymerization (ATRP) conducted in the open air was enabled by the continuous conversion of oxygen to carbon dioxide catalyzed by glucose oxidase (GOx), with glucose and sodium pyruvate as sequential sacrificial substrates. Controlled ...


Cooperative formation of long‐range ordering in water ad‐layers on Fe3O4(111)

04.12.2017 | Francesca Mirabella, Eman Zaki, Francisco Ivars-Barcelo, Xiaoke Li, Joachim Paier, Joachim Sauer, Shamil Shaikhutdin ..., Angewandte Chemie, 2017

The initial stages of water adsorption on magnetite Fe3O4(111) surface and the atomic structure of the water/oxide interface remain controversial. Herein, we provide experimental results obtained by infrared reflection‐absorption spectroscopy (IRAS) and temperature programmed desorption (TPD), ...


Reducing the Charge Carrier Transport Barrier in Functionally Layer‐Graded Electrodes

20.10.2017 | Xiaodong Chen, Yanyan Zhang, Oleksandr I. Malyi, Yuxin Tang, Jiaqi Wei, Zhiqiang Zhu, Huarong Xia, Wenlong Li, Jia G ..., Angewandte Chemie, 2017

Abstract Lithium‐ion batteries (LIBs) are primary energy storage devices to power consumer electronics and electric vehicles, but their capacity is dramatically decreased at ultrahigh charging/discharging rates. This mainly originates from a high Li‐ion/electron transport barrier within a ...


Noncovalent Functionalization and Charge Transfer in Antimonene

17.10.2017 | Gonzalo Abellán, Pablo Ares, Stefan Wild, Edurne Nuin, Christian Neiss, David Rodriguez-San Miguel, Pilar Segovia, C ..., Angewandte Chemie, 2017

Abstract Antimonene, a novel group 15 two‐dimensional material, is functionalized with a tailormade perylene bisimide through strong van der Waals interactions. The functionalization process leads to a significant quenching of the perylene fluorescence, and surpasses that observed for either ...


A Space‐Charge Treatment of the Increased Concentration of Reactive Species at the Surface of a Ceria Solid Solution

12.10.2017 | Alexander F. Zurhelle, Xiaorui Tong, Andreas Klein, David S. Mebane, Roger A. De Souza, Angewandte Chemie, 2017

Abstract A space‐charge theory applicable to concentrated solid solutions (Poisson–Cahn theory) was applied to describe quantitatively as a function of temperature and oxygen partial pressure published data obtained by in situ X‐ray photoelectron spectroscopy (XPS) for the concentration of ...


Crystal Structure and Luminescence Properties of the First Hydride Oxide Chloride with Divalent Europium: LiEu2HOCl2

09.10.2017 | Daniel Rudolph, David Enseling, Thomas Jüstel, Thomas Schleid, Zeitschrift für anorganische und allgemeine Chemie, 2017

The mixed‐anionic hydride oxide chloride LiEu2HOCl2 with divalent europium was synthesized by the reduction of Eu2O3 with LiH in a LiCl flux at 750 °C for 4 d in silica‐jacketed niobium capsules. According to structure determination by single‐crystal X‐ray diffraction the yellow compound ...
