Rattling in the Quadruple Perovskite CuCu3V4O12

23-Jul-2015 | Yasuhide Akizuki, Ikuya Yamada, Koji Fujita, Kazuya Taga, Takateru Kawakami, Masaichiro Mizumaki, Katsuhisa Tanaka, Angewandte Chemie International Edition, 2015

Abstract Of particular interest is a peculiar motion of guest atoms or ions confined to nanospace in cage compounds, called rattling. While rattling provides unexplored physical properties through the guest–host interactions, it has only been observed in a very limited class of materials. ...


An efficient microwave-assisted synthesis of cotinine and iso-cotinine analogs from an Ugi-4CR approach

21-Jul-2015 | Luis Angel Polindara-García; Dario Montesinos-Miguel; Alfredo Vazquez, Organic & Biomolecular Chemistry, 2015

A convenient base-mediated two-step synthesis of cotinine analogs and a one-pot base-free synthesis of iso-cotinine derivatives featuring an Ugi-4CR/cyclization protocol, are reported. These approaches exploit the reactivity of the peptidyl position present in the Ugi adducts, allowing the facile ...


Sensors, Vol. 15, Pages 16956-16980: Real-Time Personalized Monitoring to Estimate Occupational Heat Stress in Ambient Assisted Working

13-Jul-2015 | Pancardo, Pablo ; Acosta, Francisco D.; Hernández-Nolasco, José Adán; Wister, Miguel A.; López-de-Ipiña, Diego, Sensors, 2015

Ambient Assisted Working (AAW) is a discipline aiming to provide comfort and safety in the workplace through customization and technology. Workers’ comfort may be compromised in many labor situations, including those depending on environmental conditions, like extremely hot weather conduces to ...


Supercritical Fluids Processing: A Rapid, One-Pot Exfoliation for Surfactant-Free Hexagonal Boron Nitride Nanosheets

08-Jul-2015 | Thangasamy P; Sathish Marappan, CrystEngComm, 2015

We demonstrate a simple, rapid, one-pot exfoliation of h-boron nitride for generating surfactant-free nanosheets from a supercritical mixture of iso-propanol and water. The product was characterized by powder X-ray diffraction, UV-visible, FT-IR, Field-emission scanning electron microscope and ...


ChemInform Abstract: A Simple Iridicycle Catalyst for Efficient Transfer Hydrogenation of N‐Heterocycles in Water.

02-Jul-2015 | Dinesh Talwar, Ho Yin Li, Emma Durham, Jianliang Xiao, ChemInform, 2015

Abstract First time, a cyclometalated iridium complex is used to catalyze the transfer hydrogenation of (iso)quinolines, indoles, and pyridinium salts in an aqueous solution of HCOOH/HCOONa under mild conditions.


Prediction of the long‐term corrosion rate of copper alloy objects

01-Jul-2015 | K. Kreislova, H. Geiplova, Materials and Corrosion, 2015

Comparative atmospheric corrosion data for different metal alloys can be used to predict the service life of a component, maintenance requirements, and metal loss to the environment. In some international projects some prediction models have been derived for the atmospheric corrosion rate of ...


Mechanisms of Fatal Cardiotoxicity following High-Dose Cyclophosphamide Therapy and a Method for Its Prevention

26-Jun-2015 | Takuro Nishikawa et al., PLoS ONE, 2015

by Takuro Nishikawa, Emiko Miyahara, Koichiro Kurauchi, Erika Watanabe, Kazuro Ikawa, Kousuke Asaba, Takayuki Tanabe, Yasuhiro Okamoto, Yoshifumi Kawano Observed only after administration of high doses, cardiotoxicity is the dose-limiting effect of cyclophosphamide (CY). We investigated the ...


Disposition of Astragaloside IV via Enterohepatic Circulation Is Affected by the Activity of the Intestinal Microbiome

22-Jun-2015 | Yi Jin; Xingjie Guo; Bo Yuan; Wenhong Yu; Hao Suo; Zhiyuan Li; Haiyan Xu, Journal of Agricultural and Food Chemistry, 2015

Astragaloside IV (ASIV) is a typical bioactive constituent of Radix Astragali. The study aimed to investigate the enterohepatic circulation of ASIV and evaluate the impact of activity of intestinal microbiota on the deposition of ASIV. The amounts of ASIV and its metabolites were quantified by an ...


Energies, Vol. 8, Pages 6033-6058: Energy Crop-Based Biogas as Vehicle Fuel—The Impact of Crop Selection on Energy Efficiency and Greenhouse Gas Performance

18-Jun-2015 | Börjesson, Pål ; Prade, Thomas ; Lantz, Mikael ; Björnsson, Lovisa, Energies, 2015

The production of biogas from six agricultural crops was analysed regarding energy efficiency and greenhouse gas (GHG) performance for vehicle fuel from a field-to-tank perspective, with focus on critical parameters and on calculation methods. The energy efficiency varied from 35% to 44%, ...


Hydroalumination of Ketenimines and Subsequent Reactions with Heterocumulenes: Synthesis of Unsaturated Amide Derivatives and 1,3-Diimines

02-Jun-2015 | Xing Jin; Matthias Willeke; Ralph Lucchesi; Constantin-Gabriel Daniliuc; Roland Fröhlich; Birgit Wibbeling; Werner U ..., The Journal of Organic Chemistry, 2015

The series of differently substituted ketenimines 1 was hydroluminated using di-iso-butyl aluminum hydride. For the sterically congested ketenimine 1a, preferred hydroalumination of the C═N-bond was proven by X-ray crystallography (compound 5a). In situ treatment of the hydroaluminated ...
