The performance of insulators when exposed to pollution is a very critical issue which highly affects the external insulation design of the power transmission lines and stations. This paper deals with investigation of the operating conditions of porcelain and glass insulators under artificially contaminated cases. The level of contamination on the ...

This paper examines the pressure effect on the crystallization rate of the pharmaceutically active enantiomerically pure S-enantiomer and the racemic mixture of the well-known drug ibuprofen. Performed experimental studies revealed that at ambient pressure S-ibuprofen crystallizes faster than the racemic mixture. When the pressure increases, the cr...

Ferroelectric properties of haloantimonates(III) and halobismuthates(III) have been detected for as much as 40 structures belonging to 7 different types of anionic networks, with RMX4, R2MX5, R3M2X9, and R5M2X11 stoichiometries being the most frequently reported to host these properties. We report on the first ferroelectric of the halobismuthate(II...

Metal-formate frameworks comprising ammonium cations as guests are proven to be a fertile ground to study various phenomena associated with the temperature-induced changes in structural, dielectric, optical, and magnetic properties. In this contribution, we revisit NH4[Cu(HCOO)3], a member of metal formates that distinguishes itself in terms of its...

Improvements in the mass resolution of a mass spectrometer directly correlate to improvements in peak identification and quantification. Here, we describe a post-processing technique developed to increase the quality of mass spectra of strongly insulating samples in laser-pulsed atom probe microscopy. The technique leverages the self-similarity of ...
A polyvinylidene fluoride (PVDF)/hydrogenated nitrile rubber (HNBR)-based flexible electroactive polymer blend was developed by generating a suitable morphology that showed a judicious combination of strength and flexibility. The blend, containing 30:70 wt/wt ratio of PVDF/HNBR, was thermoplastic elastomeric in nature and exhibited visible planar a...

Indium-gallium-zinc oxide (IGZO) thin films have attracted significant attention for application in thin-film transistors (TFTs) due to their specific characteristics, such as high mobility and transparency. The performance of a-IGZO TFTs with four different insulators (SiO2 Si3N4, Al2O3 and HfO2) is examined using a numerical simulator (Silvaco At...

The present paper explores two approaches which, based on the measurement of the two first natural frequencies, allow the identification of the tension force in cables with insulators. For this purpose, the nonlinear mathematical model of the mechanical system and its Finite Element discretization are firstly stated. Besides, free-vibrations experi...
Atomic scale imperfections, know as point defects, dictate the performance and efficiency of many modern energy materials. The challenges of climate change require the continued improvement and identification of materials which can have point defects engineered in a favorable fashion for the application of interest. With the rise of computer-aided ...
