in this study, kinetics and mechanism of the sulfur dioxide adsorption on the single-walled carbon nanotubes (cnt) are investigated. three single-walled carbon nanotubes, including the armchair (6,6), chiral (6,5) and zigzag (6,0) cnts were chosen as the models and the different orientations of so2 molecule relative to the cnt axis were considered. the b3lyp functional within the 6-31g(d) basis...

The aim of the CERN/RD50 collaboration is the improvement of the radiation tolerance of semiconductor detectors for future experiments at high-luminosity colliders. In the RD50 framework, evidence of enhanced signal charge in severely irradiated silicon detectors (diodes, segmented planar and 3D devices) was found. The underlying mechanism was labelled charge multiplication. This has been one o...

This article deals with the role of fish's body and object's geometry on determining the image spatial shape in pulse Gymnotiforms. This problem was explored by measuring local electric fields along a line on the skin in the presence and absence of objects. We depicted object's electric images at different regions of the electrosensory mosaic, paying particular attention to the perioral region ...

one of the most dazzling events in the atmosphere is lightning. during updrafts in the life cycle of cumulus clouds, collision of graupels and ice crystals in the presence of liquid water results in vertical separation of electrical charges and lightning. there are four types of lightening depending on the location of discharge. the first type is cloud-to-ground lightning or fork lightning that...

The external performance of quantum optoelectronic devices is governed by the spatial profiles of electrons and potentials within the active regions of these devices. For example, in quantum cascade lasers (QCLs), the electric field domain (EFD) hypothesis posits that the potential distribution might be simultaneously spatially nonuniform and temporally unstable. Unfortunately, there exists no ...

In the mid-latitude ionospheric region, sporadic-E layers (Es layers) have often been observed, revealing multiple layers. The Es layers observed during the SEEK-2 rocket campaign showed double electron density peaks; namely, there are stable lower peaks and relatively unstable upper peaks. We examined the effects of wind shear and the electric fields on the generation of the multiple layer str...

The aim of this research was to study the effect of pulsed electric fields (PEF) on the flavour profile of red-fleshed sweet cherries (Prunus avium variety Stella). The cherry samples were treated at a constant pulse frequency of 100 Hz, a constant pulse width of 20 μs, different electric field strengths between 0.3 and 2.5 kV/cm and specific energy ranging from 31 to 55 kJ/kg. Volatile compoun...

In this study, pulsed electric fields (PEFs) were evaluated as extraction-aiding technology during soymilk manufacturing to improve its isoflavone profile. Low-intensity PEFs applied at different processing conditions in two stages of the extraction process, hydrated soybeans (HSB) and soybean slurry (SBS), with extracted from conventional process control (CSM). Overall, resultant samples PEF-H...

introduction: it is important that biological and health effects from the induction of currents and fields in the body by extremely low frequency (elf) fields are fully explored to determine the effects produced at the molecular, cellular and organ levels. the objective of this study was to evaluate the intensity of elf electromagnetic fields and its probable relationship with hematological cha...
