Methyl acrylate (MA) monomer was grafted onto ultra-high molecular weight polyethylene (UHMWPE) fibers by gamma-ray pre-irradiation induced graft polymerization. The grafting of MA on UHMWPE fiber was confirmed by thermogravimetric analysis and Fouri

A detailed study was explored to compare the transient absorption spectra of the neat 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4]) with its solution in water or acetonitrile. It was concluded that the excited triplet state (3)[bmim](+c

In this paper, the melting process of 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) crystals confined in carbon nanotubes were investigated using molecular dynamics simulation. The confined ions formed a “shell-chain” structure wi

The radiation chemical yields of F ions (G(F(-)) values) were measured for a group of imidazolium-based room-temperature ionic liquids following (60)Co gamma ray irradiation. The G(F(-)) values of ionic liquids: hexafluorophosphate, bis[(trifluoromet

Radiation resistance of cross-linked polytetrafluoroethylene (XPTFE) sheets was evaluated by measuring the friction and wear properties as well as observing the morphology after gamma-irradiation in air at room temperature. The wear resistance of XPT

The effect of gamma ray irradiation on ultra-high molecular weight polyethylene (UHMW-PE) fibre was investigated for the change of gel fraction, mechanical properties, and morphology of crystallites. In the case of irradiation in air, the oxidation w

An in situ X-ray absorption fine structure (XAFS) experiment has been performed to observe the evolution of gold nanoparticles in the ionic liquid [BMIM][AuCl4], by hard X-ray irradiation. The ionic liquid acts as both a reducing agent and a protecti

Stable gold nanoparticle (AuNP) colloids were synthesized in a class of quaternary ammonium-based room-temperature ionic liquids (QAILs), [Me(3)NC(2)H(4)OH](+)[Zn(n)Cl(2n+1)](-) (n = 1 or 2), by heating in air at 135-145 degrees C. The QAIL was emplo

[Emim]Br ionic liquid was confined in porous SiO2 nanoparticles. It is shown that the confinement in the nanopores leads to a compression of molecular size and an increase in the melting point. The pore size of SiO2 is a key factor in tuning the anio

In this work, we demonstrate for the first time that hydrophobic ILs can be strikingly tuned to be hydrophilic under a strong external electric field, with the use of nonequilibrium molecular dynamics (MD) simulations and atomic force microscopy (AFM
