ChemPlusChem Board Members in the News
We congratulate four ChemPlusChem board members for receiving recognition for their top-notch research.
Chi-Ming Che (University of Hong Kong) was elected a Foreign Associate of the US National Academy of Sciences. A recent publication describes ketimido ruthenium(IV) phthalocyanine complexes.
Guy C. Lloyd-Jones (University of Bristol) was elected a Fellow of the Royal Society. A recent paper outlines the preparation of organotrifluoroborate salts.
Evamarie Hey-Hawkins (University of Leipzig) was named among the IUPAC 2013 Distinguished Women in Chemistry or Chemical Engineering. Her most recent article in ChemPlusChem reports on phosphorus-rich manganese(I) complexes.
Krzysztof Matyjaszewski (Carnegie Mellon University) has received the Madison Marshall Award 2013 from the North Alabama Section of the ACS. A recent publication describes a bioinspired iron-based catalyst for ATRP.
Recently Published Articles
- Dual Lewis Base Functionalization of Ionic Liquids for Highly Efficient and Selective Capture of H2S
Kuan Huang, Da-Niu Cai, Yong-Le Chen, Prof. You-Ting Wu, Prof. Xing-Bang Hu and Prof. Zhi-Bing Zhang
Article first published online: 4 DEC 2013 | DOI: 10.1002/cplu.201300365
Shared labor: The dual Lewis base functionalization strategy enables the cooperative interaction of carboxyl⋅⋅⋅H2S⋅⋅⋅amine, thus significantly enhancing the H2S absorption capacity (see scheme). Conversely, the interaction of CO2 with the carboxylate group is weakened by the conjoint tertiary amine group through the electron-withdrawing effect. The interaction of CO2 with the amine group is unfavorable owing to the absence of active protons in CO2. Thus, CO2 solubility is limited.
- Assembly Dependent Fluorescence Enhancing Nucleic Acids in Sequence-Specific Detection of Double-Stranded DNA
Dr. Osman Doluca, Dr. Tracy K. Hale, Dr. Patrick J. B. Edwards, Prof. Dr. Carlos González and Dr. Vyacheslav V. Filichev
Article first published online: 2 DEC 2013 | DOI: 10.1002/cplu.201300310
A single attachment of the thiazole orange derivative to 2′-O-propargyl nucleotide in the structure of triplex-forming oligonucleotides (TFOs) led to probes with low fluorescent intensity in the single-stranded state (ΦF=0.09–1.5 %; see figure). A significant increase in fluorescent intensity was detected after formation of DNA triplexes (ΦF=23.5–34.9 %). Under similar conditions, Watson–Crick-type duplexes showed low fluorescent intensities.
- Immobilization of LaW10 onto Ionic-Liquid-Modified Mesoporous Silica: Deep Desulfurization with Zero-Order Reaction Kinetics
Yang Chen and Prof. Yu-Fei Song
Article first published online: 29 NOV 2013 | DOI: 10.1002/cplu.201300323
The immobilization of LaW10 onto ionic-liquid (IL)-modified mesoporous silica results in a new heterogeneous catalyst, LaW10/IL-SiO2, which can achieve the deep desulfurization of dibenzothiophene, benzothiophene, and 4,6-dimethyldibenzothiophene under mild conditions (see figure). The extractive catalytic oxidative desulfurization process with LaW10/IL-SiO2 does not require addition of the IL with each catalyst reuse.
- Design of a Nitrogen-Doped, Carbon-Coated Li4Ti5O12 Nanocomposite with a Core–Shell Structure and Its Application for High-Rate Lithium-Ion Batteries
Dr. Hongsen Li, Dr. Laifa Shen, Jie Wang, Dr. Bing Ding, Dr. Ping Nie, Guiyin Xu, Xiaoyan Wang and Prof. Xiaogang Zhang
Article first published online: 29 NOV 2013 | DOI: 10.1002/cplu.201300316
Made to fit: A nitrogen-doped, carbon-coated Li4Ti5O12 nanocomposite with a core–shell structure has been synthesized using the ionic liquid 1-ethyl-3-methylimdazolium tricyanomethanide as the carbon source. The well-defined nanocomposite displays better cycling and rate performances than those of Li4Ti5O12 nanoparticles, and has a superior lithium-storage capability even at high rates (see picture).
- Synthesis of 5-Ethoxymethylfurfural from Fructose and Inulin Catalyzed by a Magnetically Recoverable Acid Catalyst
Prof. Zehui Zhang, Yimei Wang, Zhongfeng Fang and Dr. Bing Liu
Article first published online: 28 NOV 2013 | DOI: 10.1002/cplu.201300301
Accelerated attraction: A new process for the synthesis of 5-ethoxymethylfurfural from fructose-based carbohydrates catalyzed by a magnetically recoverable acid catalyst is described. After the reaction, the catalyst can be readily recovered by means of an external magnet and reused several times without any loss in catalytic activity (see picture).
