Fourth stable radical species in X-irradiated solid-state sucrose

27.04.2016 | Jevgenij Kusakovskij; Ignacio Caretti; Sabine Van Doorslaer; Freddy Callens; Henk Vrielinck, Physical Chemistry Chemical Physics, 2016

High-energy radiation produces radicals in crystalline sucrose. As such, sucrose is considered as a relevant model system for studying radiation damage to the sugar units of DNA. Many of these radicals are stable, detectable at room temperature with electron paramagnetic resonance (EPR) and their ...

Shape-selective Synthesis of Sn(MoO4)2 Nanomaterials for Catalysis and Supercapacitor Applications

27.04.2016 | K Sakthikumar; Sivasankara Rao Ede; Soumya Ranjan Mishra; Subrata Kundu, Dalton Transactions, 2016

Size and shape-selective Sn(MoO4)2 nanomaterials has been synthesized for the first time using a simple hydrothermal route by the reaction of Sn(II) chloride salt with sodium molybdate in CTAB micellar media under stirring at 60 oC temperature for total three hours. Needle-like and flake-like ...

Gel integration for microfluidic applications

27.04.2016 | Xuanqi Zhang; Lingjun Li; Chunxiong Luo, Lab on a Chip, 2016

Molecular diffusive membranes or materials are important for biological applications in microfluidic systems. Hydrogels are typical materials that offer several advantages, such as free diffusion for small molecules, biocompatibility with most cells, temperature sensitivity, relatively low cost, ...

Ammonia decomposition catalysis using lithium–calcium imide

27.04.2016 | Joshua W. Makepeace; Hazel M. A. Hunter; Thomas J. Wood; Ronald I. Smith; Claire A. Murray; William I. F. David, Faraday Discussions, 2016

Lithium–calcium imide is explored as a catalyst for the decomposition of ammonia. It shows the highest ammonia decomposition activity yet reported for a pure light metal amide or imide, comparable to lithium imide–amide at high temperature, with superior conversion observed at lower temperatures. ...

Startling Temperature Effect on Proteins when Confined: Single Molecular Level Behaviour of Human Serum Albumin in Reverse Micelle

27.04.2016 | Bhaswati Sengupta; Rajeev Yadav; Pratik Sen, Physical Chemistry Chemical Physics, 2016

The present work reports the effect of confinement, and temperature therein, on the conformational fluctuation dynamics of domain-I of human serum albumin (HSA) by fluorescence correlation spectroscopy (FCS). The water-pool of sodium bis(2-ethylhexyl) sulfosuccinate (AOT) reverse micelle has been ...

Growth mechanism of aluminium-induced solid phase epitaxial (AI-SPE) Si0.5Ge0.5 layer using in-situ heating transmission electron microscopy

26.04.2016 | Chuan-jung Lin; Chien-Chung Hsu; Sheng-Min Yu; Yu-Chun Huang; Sung-Yen Wei; Wen-Ching Sun; Tzer-Shen Lin; Fu-Rong Chen, CrystEngComm, 2016

The mechanism of epitaixial Si0.5Ge0.5 layer on a single crystalline (sc) Si (100) substrate grown by aluminium-induced solid phase epitaxy (AI-SPE) at relatively low temperature (450℃) has been revealed with in-situ heating transmission electron microscopy (TEM). The analysis of thermodynamics ...

Methanol oxidation on Fe2O3 catalysts and the effects of surface Mo

26.04.2016 | M. Bowker; E. K. Gibson; I. P. Silverwood; C. Brookes, Faraday Discussions, 2016

The adsorption of methanol on haematite has been investigated using temperature programmed methods, combined with in situ DRIFTS. Model catalysts based on this material have then been made with a shell–core configuration of molybdenum oxide monolayers on top of the haematite core. These are used ...

Monte-Carlo modelling of nano-material photocatalysis: bridging photocatalytic activity and microscopic charge kinetics

26.04.2016 | Baoshun Liu, Physical Chemistry Chemical Physics, 2016

In photocatalysis, it is known that light intensity, organic concentration, and temperature affect the photocatalytic activity by changing the microscopic kinetics of holes and electrons. However, how the microscopic kinetics of holes and electrons relates to the photocatalytic activity was not ...

Achirality in the low temperature structure and lattice modes of tris(acetylacetonate)iron(III)

26.04.2016 | Thomas K. Ellis; Gordon J. Kearley; Ross O. Piltz; Upali A. Jayasooriya; John A. Stride, Dalton Transactions, 2016

Tris(acetylacteonate) iron(iii) is a relatively ubiquitous mononuclear inorganic coordination complex. The bidentate nature of the three acetylacteonate ligands coordinating around a single centre inevitably leads to structural isomeric forms, however whether or not this relates to chirality in ...

Photo-induced linkage NO isomers in the dinitrosyl complex [Ru(NO)2(PCy3)2Cl](BF4) identified by Photocrystallography and IR-spectroscopy

26.04.2016 | nicolas casaretto; bertrand fournier; Sebastien Pillet; El-Eulmi Bendeif; Dominik Schaniel; Anna K.E. Gallien; Peter ..., CrystEngComm, 2016

Photoinduced metastable linkage NO isomers have been known for a long time in mono-nitrosyl ruthenium or iron transition metal complexes [MLxLy(NO)]n for which appropriate temperature and excitation conditions allow a controlled generation of different metastable states. Dinitrosyl complexes ...
