Dehydrogenation of ammonia-borane by cationic Pd(II) and Ni(II) complexes in a nitromethane medium: hydrogen release and spent fuel characterization

01.04.2015 | Sung-Kwan Kim; Sung-Ahn Hong; Ho-Jin Son; Won-Sik Han; Artur Michalak; Son-Jong Hwang; Sang Ook Kang, Dalton Transactions, 2015

A highly electrophilic cationic PdII complex, [Pd(MeCN)4][BF4]2 (1), brings about the preferential activation of the B–H bond in ammonia-borane (NH3·BH3, AB). At room temperature, the reaction between 1 in CH3NO2 and AB in tetraglyme leads to Pd nanoparticles and formation of spent fuels of the ...

Temperature driven p–n–p type conduction switching materials: current trends and future directions

01.04.2015 | Satya N. Guin; Kanishka Biswas, Physical Chemistry Chemical Physics, 2015

Modern technological inventions have been going through a “renaissance” period. Development of new materials and understanding of fundamental structure–property correlations are the important steps to move further for advanced technologies. In modern technologies, inorganic semiconductors are the ...

Self-assembly of luminescent N-annulated perylene tetraesters into fluid columnar phases

01.04.2015 | Ravindra Kumar Gupta; Suraj Kumar Pathak; Balaram Pradhan; D. S. Shankar Rao; S. Krishna Prasad; Ammathnadu S. Achal ..., Soft Matter, 2015

A new class of N-annulated perylene tetraesters and their N-alkylated derivatives has been synthesized. N-Annulated perylene tetraesters stabilize a hexagonal columnar phase over a broad temperature range. The hexagonal columnar phase exhibited by these compounds shows good homeotropic alignment ...

Layered MoS2 nanoparticles on TiO2 nanotubes by a photocatalytic strategy for use as high-performance electrocatalysts in hydrogen evolution reactions

01.04.2015 | Chenhui Meng; Zhaoyue Liu; Tierui Zhang; Jin Zhai, Green Chemistry, 2015

An environmentally-friendly photocatalytic strategy carried out at room temperature and atmospheric pressure without using toxic precursors was used to develop high-performance MoS2 nanoparticulate electrodes consisting of layered MoS2 nanoparticles on anodized TiO2 nanotubes (TiO2-NTs). TiO2-NTs ...

Introducing a new radical trifluoromethylation reagent

01.04.2015 | Azusa Sato; Jianlin Han; Taizo Ono; Alicja Wzorek; José Luis Aceña; Vadim A. Soloshonok, Chemical Communication, 2015

Perfluoro-3-ethyl-2,4-dimethyl-3-pentyl radical (PPFR) is a persistent radical stable at room temperature, but easily decomposes at 90 °C to produce a CF3 radical which is able to react with a variety of aromatic compounds to afford the corresponding trifluoromethyl derivatives, usually as ...

An old workhorse for new applications: Fe(dpm)3 as a precursor for low-temperature PECVD of iron(III) oxide

01.04.2015 | G. Carraro; C. Maccato; A. Gasparotto; D. Barreca; M. Walter; L. Mayrhofer; M. Moseler; A. Venzo; R. Seraglia; C. Marega, Physical Chemistry Chemical Physics, 2015

An iron(iii) β-diketonate complex, Fe(dpm)3 (Hdpm = 2,2,6,6-tetramethyl-3,5-heptanedione), has been investigated as a potential precursor for plasma enhanced chemical vapor deposition (PECVD) of iron(iii) oxide nanomaterials. Thanks to the combined experimental–theoretical approach, spectroscopic ...

N-H[middle dot][middle dot][middle dot][small pi] induced configurational isomerism and the role of temperature in the Z to E isomerization of 2-fluoro-N-(3-fluorophenyl) benzimidamide

01.04.2015 | Deepak Chopra; Dhananjay Dey, CrystEngComm, 2015

We have investigated the role of N-H···π interaction in the formation of Z/E configurational isomers (including dimorphism in the E isomer) of 2-fluoro-Ń-(3-fluorophenyl)benzimidamide. The lowering of the crystallization temperature by ~20 C results in a new form (Z isomer). Single crystal X-ray ...

Condensation of vapor species at the outlets in the high temperature chemical vapor deposition using tetramethylsilane as the precursor for SiC bulk growth

01.04.2015 | Byeong Geun Kim; Ji-Young Yoon; Chang-Hyoung Yoo; Deok-Hui Nam; Myung-Hyun Lee; Won-Seon Seo; Seong-Min Jeong, CrystEngComm, 2015

High temperature chemical vapor deposition (HTCVD), an alternate method for crystal growth of SiC, was recently deemed to be a safe method when tetramethylsilane (TMS) is used. In this study, we report on the characteristics of condensation of vapor species as a function of geometric location and ...
