Melting can follow many pathways
Phase Transformation Melting involves the loss of order as additional kinetic energy is added to a system. Although simple models of this sort of phase transition exist, it can be very difficult to observe the initial stages either experimentally or using simulations. Samanta et al. developed a
ChemInform Abstract: Synthesis and Characterization of the New Lead Strontium Germanate PbSrGeO4.
Abstract PbSrGeO4 is prepared by a high‐temperature reaction of stoichiometric amounts of PbO, SrCO3, and GeO2 (platinum crucible, 900 °C, 130 h).

This paper presents both the description and the iconographic documentation of a mite species new to science: Orthadenella coulsoni sp. nov., recorded from Siberia, Russia. A key for determining females of all species within this genus is included.http://zoobank.org/urn:lsid:zoobank.org:pub:3B416529-A22D-43B3-96BD-3D5…
Global initiatives in waste gasification
Municipal Solid Waste (MSW) residues usually occur in a combination of wet and combustible forms, requiring separate or sequential treatments by bio-and thermo-chemical processes, rather than incinerating under a mixture of auxiliary fuel addition. Thermo-chemical decomposition of poor carbonaceous fuels into energy-r…
Cover Picture: Inherently Chiral Macrocyclic Oligothiophenes: Easily Accessible Electrosensitive Cavities with Outstanding Enantioselection Performances (Chem. Eur. J. 47/2014)
When new topologically appealing molecules are formed, fantasy-assisted cogitation tries to associate their shapes to objects of everyday life: knots, cylinders, pretzels, baskets, ladders, etc. Chirality adds a touch of intelligence to these molecules, which gain the ability to recognize enantiomorphic species. In th…
ChemInform Abstract: A Structural Comparison of Two Thallium Copper Erbium Sulfides: TlCu3Er2S5 and Tl2Cu5Er3S8.
Abstract Orange TlCu3Er2S5 (I) is prepared by solid state reaction of a 2:1:3 molar mixture of Cu, Er, and S to which an excess TlCl is given as a flux (evacuated silica tubes, 850 °C, 8 d).
Copolymer and platinum ion assisted growth of functionalized gold nanonests
Novel Au nanonests with high yield and uniformity were successfully synthesized using P123 as a soft template and a reductant in an ice water bath with and without the presence of the second metallic source of Pt ions.
Crystal structure of diaqua bis(di(pyrazin-2-yl)sulfane-κ1N)bis(acetato-κ1O)cobalt(II), C20H22CoN8O6S2
Article Crystal structure of diaqua bis(di(pyrazin-2-yl)sulfane-κ1N)bis(acetato-κ1O)cobalt(II), C20H22CoN8O6S2 was published on December 1, 2014 in the journal Zeitschrift für Kristallographie - New Crystal Structures (volume 229, issue 4).
Cover Picture: Controlled Synthesis of Nanoporous Nickel Oxide with Two‐Dimensional Shapes through Thermal Decomposition of Metal–Cyanide Hybrid Coordination Polymers (Chem. Eur. J. 9/2015)
The chemoselective trifluoromethylthiolation of nitrogen nucleophiles and thiols using N-(trifluoromethylthio)phthalimide under mild, metal-free conditions is described. A series of trifluoromethanesulfenamides and unsymmetrical disulfides is prepared from the corresponding aliphatic and aromatic amines and thiols in…
Behaviour of master alloy during sintering of PM steels: Redistribution and dimensional variations
The addition of alloying elements in low alloyed PM steels in the form of a master alloy gives the advantage of introducing oxidation sensitive but less expensive elements and also allows manipulation in composition adjustment to achieve desired properties. In this work, interrupted sintering trials of the Fe–2MA–0.5C…

Impurity Effect on the Inter-Chain Dielectric Response of the CDW Condensate in K0.3MoO3
We study the effect of impurity on the charge-density-wave (CDW) state via low-frequency dielectric measurements, especially for the inter-chain direction. The extremely high dielectric constant seen in non-doped K0.3MoO3 is strongly reduced by W- or V-doping, demonstrating that the three-dimensional (3D) phase rigidi…
Electrochemical assembling of methionine-gold nanoparticles and catalysis on the surface of glassy carbon electrode
In this paper cyclic voltammetry was used for the synthesis of linear array spherical gold nanoparticles on the surface of glassy carbon electrode using methionine as a stable reagent. The methionine-gold nanoparticles on the surface of glassy electrode were obtained. The methionine-gold nanoparticles were characteriz…

The Sr 3 Y(PO 4 ) 3 :0.05Sm 3+ , Sr 3 Y(PO 4 ) 3 :0.005Tb 3+ , and Sr 3 Y(PO 4 ) 3 :0.005Tb 3+ , 0.05Sm 3+ phosphors were synthesized using a conventional solid-state reaction technique at high temperature and their photoluminescence properties under ultraviolet (UV) excitation were studied. We observed the UV sensiti…
Modulated retroreflector based on metallic nanoshells for applications in the visible band
In our research, we have theoretically studied a device that can serve as a modulating retroreflector (MRR) for applications in the visible spectrum. The device is comprised of a nanocomposite of a ferroelectric thin-film embedded with noble metal nanoshells. In comparison to the nanospheres, the nanoshells provide mo…
Influence of Hydrolysis on Diffusion of Electrolytes
Experimental mutual diffusion coefficients of potassium chloride, magnesium nitrate, cobalt chloride and beryllium sulphate in aqueous solutions have been compared with those estimated by the Onsager-Fuoss. From the observed deviations, we are proposing a model that allows to estimate the percentages of H 3 O + (aq) r…
Magnetic characterization techniques for monitoring gas pipelines under severe loading
The reliable operation of trunk pipelines requires efficient monitoring of their technical state. At present, the issues involving evaluation of stress and strain in the most dangerous black spots of pipelines are urgent for the oil-and-gas industry. The problem is especially pressing for operations in corrosion-activ…
Giant and flux controllable pumping of water molecules in a double-walled carbon nanotube
We designed a water pumping system based on double-walled carbon nanotube. In this system, the inner tube was fixed as the water channel, while the exterior was moved similarly to the piston motion along the axial direction to induce pumping force. Molecular dynamics simulations confirmed that the water flux is sensit…
