A new high-temperature NMR technique for measurements of the phase transition kinetics in solids has been developed. The technique allows measuring the time evolution of the volume of the appearing phase at controlled cooling rates. Developed method was applied to study the phase transition kinetics in the superionic…
We consider a binary Lennard-Jones glassformer whose super-Arrhenius dynamics are correlated with the formation of icosahedral structures. Upon cooling, these icosahedra organize into mesoclusters. We recast this glassformer as an effective system of icosahedra which we describe with a population dynamics model. This…
Abstract Caged siRNAs with a single photolabile linker and/or vitamin E (vitE) modification at the 5′ terminal were rationally designed and synthesized. These virtually inactive caged siRNAs were successfully used to photoregulate both firefly luciferase and GFP gene expression in cells with up to an 18.6‐fold enhance…
Viscose fiber reinforced polypropylene (PP/VF) composites were manufactured using long fiber thermoplastic (LFT) extrusion techniques with two different methods namely LFT-l and LFT-2. The compatibilizer [maleated polypropylene (MAPP)] and dispersing agent [stearic acid (SA)] were added to the PP/VF in order to improv…
Macromolecular brushes with cleavable pendant chains were synthesized by controlled free radical polymerizations and functional nanocapsules were fabricated on the basis of the brush polymers.
A theoretically informed Monte Carlo method is proposed for Monte Carlo simulation of liquid crystals on the basis of theoretical representations in terms of coarse-grained free energy functionals. The free energy functional is described in the framework of the Landau-de Gennes formalism. A piecewise finite element di…
Recently [S. Capponi, S. Napolitano, and M. Wübbenhorst, Nat. Commun. 3, 1233 (2012)], vapor deposited glasses of glycerol have been found to recover their super-cooled liquid state via a metastable, ordered liquid (MROL) state characterized by a tremendously enhanced dielectric strength along with a slow-down of the…
A novel di-functional system was synthesized by encapsulation of superparamagnetic Fe3O4 and a therapeutic agent 5-fluorouracil (5-Fu) with the thermo-responsive poly(N-isopropylacrylamide) (PNIPAM), which was coated with mesoporous SiO2 nanoparticles in a mesoporous core–shell structure. The system featured functiona…
Oriental Journal of Chemistry is a peer reviewed quarterly research journal of pure and applied chemistry. It publishes standard research papers in almost all thrust areas of current chemistry of academic and commercial importance. It provides a platform for rapid publication of quality research papers, reviews and ch…
Ge 0.77 Ag 0.1 Sb 0.13 Te 1 alloy was fabricated by a novel two-step route. Firstly, oxide reagents were melted at high temperature and quenched into pellets. The pellets were milled to powder and then reduced in hydrogen at various temperatures for various periods of time. Energy-dispersive x-ray analysis indicated t…

For low energy reaction studies involving radioactive ion beams, the experimental reaction yields are generally small due to the low intensity of the beams. For this reason, the stacked target technique has been often used to measure excitation functions. This technique offers considerable advantages since the reactio…
More than 165 induction times of butyl paraben–ethanol solution in a batch moving fluid oscillation baffled crystallizer with various amplitudes (1–9 mm) and frequencies (1.0–9.0 Hz) have been determined to study the effect of COBR operating conditions on nucleation. The induction time decreases with increasing amplit…
A detailed experimental investigation of the effects giving rise to the magnetic energy level structure in the vicinity of the level crossing (LC) at low temperature is reported for the open antiferromagnetic molecular ring Cr8Zn. The study is conducted by means of thermodynamic techniques (torque magnetometry, magnet…
O/S doping promotes the dissociation of O <sub>2</sub> , which forming epoxy and/or carbonyl groups on the doped-GP surfaces. The catalytic loop for the oxidation of SO <sub>2</sub> is terminated because of high oxidation barrier due to the formation of the carbonyl group.
Light absorption and plasmon – exciton interaction in three-layer nanorods with a gold core and outer shell composed of molecular J- and H-aggregates of dyes, Shapiro, B.I., Tyshkunova, E.S., Kondorskiy, A.D., Lebedev, V.S.
We used a combination of ion cascades and the unified thermal spike model to study the electronic effects from 800 keV Kr and Xe ion irradiation in zircon. We compared the damage production for four cases: (a) due to ion cascades alone, (b) due to ion cascades with the electronic energy loss activated as a friction te…
Development of Raman spectroscopy, profiting from surface‐enhanced Raman scattering and tip‐enhanced Raman scattering techniques, has inspired extensive research interest for trace analysis and dynamic measurements up to single‐molecule level. For another, Raman spectroscopy has also been recognized of significance in…
The synthesis of new 2-cycloalkyl-2-oxazoline monomers, namely 2-cyclobutyl (cBuOx), 2-cyclopentyl (cPentOx) and 2-cyclohexyl-2-oxazoline (cHexOx) is described. Polymers thereof are semi-crystalline and reveal unexpectedly high melting transitions.
β-Chitin/silk fibroin/nanohydroxyapatite (CT/SF/nHAp) composite scaffolds were synthesized using a freeze-drying method by blending β-chitin hydrogel, silk fibroin and nHAp at different inorganic/organic weight ratios.
