We review the effect of water anomalies on the properties of low-temperature water. When supercooled, liquids dynamical properties change drastically. Supercooled liquids undergo an at least exponential decrease of their diffusion coefficient when temperature decreases while their structure merely does not change. We…
The effect of hydrated electron scavengers, Cd2+, NO3−, (CH3)2CO, and OH radical scavengers, Cl−, I−, on the intensity of Ru(bpy)32+ ion sonochemiluminescence observed in neutral aqueous solutions of Ru(bpy)3Cl2 was studied. The variation trends in the luminescence intensity due to the action of the scavengers indicat…
Entanglements between polymer chains are responsible for the strength and toughness of polymeric materials. When the chains are too short to form entanglements, the polymer becomes weak and brittle. Here we show that molecular bridging of oligomers in molecular-scale confinement can dramatically toughen materials even…
Small co-solute molecules containing unpaired electrons can impart strong perturbations on nuclear shielding and nuclear relaxation of dissolved compounds, and thereby form a potent class of non-covalent probes for molecular science. These paramagnetic co-solutes range from exquisite lanthanoid and transition metal co…
The well-known difficulty to obtain high-quality protein crystals has motivated researchers to come up with new methods or modifications of established crystallization methods to stimulate the growth of good diffracting crystals. In the present work, a new approach, using a protein thin film organized by external elec…

Graphene materials especially single‐layer graphene have been identified as a new generation of nanomaterials having various potential applications in material industries. However, the synthesis procedure of single‐layer graphene to improve its quality, size and amount has been still under research for commercial appl…
Abstract Understanding the molecular interaction and morphology of organic-inorganic hybrid materials is an important and fundamental assignment to develop novel high-performance materials. In this work, we developed two types of hybrid coating materials by using different silane coupling agents via Michael addition r…
Abstract Nanodielectrics have been expected to improve the electrical performance and are considered as dielectrics for the future. It has been recognized that the electrical performance is closely related to charge dynamics in the dielectrics material. However, the mechanism of charge dynamics in the interphase of na…
In this paper, we report a simple, low-cost, and environmentally friendly electrochemical method to obtain a novel copolymer consisting of 1-pyrenyl-2,5-di(2-thienyl)pyrrole and pyrrole on a pencil graphite electrode (PGE). Poly(1-pyrenyl)-2,5-di(2-thienyl)pyrrole-co-pyrrole) that is P(PyrPy-co-Py) film was prepared b…

Origin of mixed valence states from π-conjugated photoresponsive systems offers self-assembled nanostructures facilitating excellent optoelectronic properties. Despite various electron-rich moieties, tethered linear π-conjugated systems generate charged ions however limited to standard redox-active materials until now…
We report the results of extensive molecular dynamics (MD) simulation of water in a carbon nanotube (CNT) with a specific diameter over a wide range of temperatures from 343 to 423 K. In order to characterize the nature of water, we have computed the Kirkwood g-factor, the ten Wolde parameter, the radial distribution,…
Supported metal films are often found to display extraordinary properties compared to their bulk counterparts. In this work, we investigate the atomic and electronic structures of both the Au/Cu(111) and Cu/Au(111) thin films with low-temperature scanning tunneling microscopy (STM) and synchrotron radiation photoelect…
The effect of annealing on the structural and optical properties of thermally evaporated Ge30Se70 and Ge30Se60Bi10 thin films is reported in this paper. The prepared films were thermally annealed at 250°C to optimize the optical properties which can be used for the optical device fabrication. X-ray diffraction study r…
Polyurethanes are materials with a strong structure-property relationship. The goal of this research was to study the effect of a polyol blend composition of polyurethanes on its properties using a mixture design and setting mathematic models for each property. Water absorption, hydrolytic degradation, contact angle,…
Small spheres released above the liquid surface experience a dynamic process to ultimately float or sink, and thus, their behaviors should be considered by dynamic analysis instead of static equilibrium. This study numerically investigates the motion of small spheres after contacting the liquid surface with zero veloc…
A series of polyurethane (PU) films were synthesized via one-shot bulk polymerization with polyethylene glycol, castor oil, hexamethylene diisocyanate, and 1,4-butanediol (BD) at three different chain extender ratios. Since it was found in our previous study that hard segment content is more effective on shape memory…
nanocluster has been analyzed through density functional theory (DFT) and time-dependent density functional theory (TDDFT) simulations. Starting from two different X-ray diffraction (XRD) resolved structures which differ in the ligand orientation, we optimized the methyl substituted neutral nanoclusters at the B3LYP//…
We report an investigation of the structural, magnetic and electronic properties of Ba(Fe 1− x V x ) 2 As 2 using x-ray, transport, magnetic susceptibility and neutron scattering measurements. The vanadium substitutions in Fe sites are possible up to ∼ 40%. Hall effect measurements indicate strong hole-doping effect t…
