In this compilation, the authors describe a volume source of negative hydrogen ions on the basis of Penning ionization gauge with a metal hydride cathode, which plays the role of a cathode and the solid-state generator of working gas. Next, a study is carried out in two cases of constant and variable charges of dust grains. Consideration of the dust charge variation requires the evaluation of charging currents. The possibilities of ultra short pulsed laser deposition for modified scratch-resistant surfaces in industrial and optical applications are demonstrated and reviewed. Additionally,...

Horizons in World Physics. Volume 303 begins by examining hyperacute vision experiments based on the eye of a house fly which use solid state electronics to obtain a 10 fold improvement over digital camera technology. This contradicts neuroscience models of hyperacuity based on cortical processing because the house fly does not have a cortex. Following this, the protocol of the seventh dialogue with Uranus inhabitants, including the invitation procedure, is presented and logically analyzed, along with the method for generating gravitational radiation by a neutrino graser. The authors consider...

In Horizons in World Physics. Volume 298, the authors open with an examination of the appearance of special properties of nanofractals in various phenomena, such as fractal Au-nanocatalysis, Fano resonance in fractal quantum dots, the role of nanofractals in solar cell interfaces, and the use of different sized DNA fragments in a new separation method. Following this, a high speed full spectrum Fiber Bragg gratings interrogation is presented, which allows for the full distorted spectrum of the Fiber Bragg gratings to be sampled during a dynamic high strain rate event. This is done by using a...

In this compilation, the authors discuss how the necessity of the complexification of physics, meaning that all physical quantities must be defined within the field of complex numbers. The results of Shnoll experiments that revealed the fine structure of the distribution of all general measurands, which differed from classical Poisson and Gauss distributions, are interpreted in terms of complex physical quantities, making it possible to estimate magnitudes of imaginary parts and to suggest the time and space dependence. Next, Horizons in World Physics. Volume 300 reviews studies on...

Horizons in World Physics. Volume 299 opens with a study on the analysis of photoluminescence spectra of II-VI-based thin films (pure II-VI semiconductor compounds CdTe, ZnTe, CdSe, Cd1-xZnxTe ternary compound, CdS:Dy rare-earth element doped II-VI compound) at different substrate temperatures.Next, the authors introduce a novel universal carrier-guided nanopore dielectrophoresis technology that can selective capture and detection of single nucleic acid molecules. In this approach, each target nucleic acid molecule is hybridized with a designed cationic carrier to impart a tunable synthetic...
