Electrical Contact Resistance of Large-Area Graphene on Pre-Patterned Cu and Au Electrodes Contact resistance between electrically connected parts of electronic elements can negatively affect their resulting properties and parameters. The contact resistance is influenced by the physicochemical properties of the connected elements and, in most cases, the lowest possible value is required.... |

Bioresonance According to Paul Schmidt (BaPS) and its Beneficial Effects on the Integrity of the Intestinal Barrier in vitro The intestinal epithelium, which is only one cell layer thick, has two essential tasks. The first is to create a physical barrier between the contents of the intestinal lumen and the rest of our body. The second is to ensure an efficient absorption of essential nutrients&... |

Simultaneous detection of NH3 and N02 by modified impedance spectroscopy in sensors based on carbon nanotubes There are many gaseous substances that need to be monitored for possible damage to health or the environrnent. This requires many sensors. The solution to reducing the number of sensors is to use one sensor to detect several gaseous substances simultaneously. Efforts to simplify... |

Density of bulk trap states of hybrid lead halide perovskite single crystals: temperature modulated space-charge-limited-currents Temperature-modulated space-charge-limited-current spectroscopy (tMsCLC) is applied to quantitatively evaluate the density of trap states in the band-gap with high energy resolution of semiconducting hybrid lead halide perovskite single crystals. Interestingly multicomponent deep trap states were observed in th... |

Raman spectroscopy and DFT calculations of PEDOT:PSS in a dipolar field The conductive polymer-electrolyte interface plays an important role in many electrochemical devices. An unusual situation arises when a solvent-free ionic liquid (SF-IL) is used as the electrolyte because it behaves as a molten salt rather than an electrolyte solution. On the basis of&... |
