Abstract Extreme-high-speed communication exceeding 100 Gbps is one requirement for 6G. To satisfy extreme-high-speed-communication, solution to utilize terahertz bands above GHz. determine the new radio-interface technologies and service frequency 6G, propagation characteristics GHz need be understood. In this paper, we introduce our radio-network topology 6G then show dependency of key phenom...

By the experiment, the optimal technological conditions that the water and oil repellent finishing agent EX-910E is applied in polyester nonwovens were confirmed. The technological conditions include that EX-910E usage is 40g/l, the bridging agent F-2921E usage is 6g/l, the pre-curing condition is 100 × 2/3min, and the curing condition is 160 × 2.5 min. The results of the experiment indicated t...

Efficient decolorization of Rhodamine 6G dye (Rh 6G) using magnetic TiO2@Fe3O4/FeZSM-5 photocatalyst was carried out in a batch reactor equipped with two visible lights (high-pressure Na lamps). The synthesized and characterized by X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, diffuse reflectance spectroscopy vibrating sample magnetometry. effects initial Rh c...

Research on the sixth-generation cellular networks (6G) is gaining huge momentum to achieve ubiquitous wireless connectivity. Connected autonomous vehicles (CAVs) a critical vertical application for 6G, holding great potentials of improving road safety, and energy efficiency. However, stringent service requirements CAV applications reliability, latency, high speed communications will present bi...

We briefly report the case of a female patient 46 y.o. affected by Myotonic muscular dystrophy (Steinert Disease) who underwent a laparotomic hysterectomy. A 46-year-old female (height 165 cm, weight 67 kg) presented to emergency department for metrorrhagia and anemization due to the presence of unknown multiple uterine myomas. She has hemoglobin level of 6, 6g/ dl and she was admitted to Gynec...

We provide a conclusive demonstration of vibrational pumping under Surface Enhanced Raman Scattering (SERS) conditions by performing anti-Stokes/Stokes ratio measurements over a large spatial area and low power density, down to 10 K with dried silver colloids, the dye rhodamine 6G, and 676 nm laser excitation. The method we propose allows for the measurement of the cross sections for different ...

Solution doping of microstructured polymer optical fibres [mPOF] is demonstrated, a technique which allows dopants to be introduced after polymerisation through the microstructure. Controlled diffusion is used to disperse the dopant uniformly across the fibre core, and the final concentration can be systematically varied by appropriate choice of conditions. We use this technique to produce a fi...

This investigation explores, for the first time, the random laser behavior of ground powder obtained from organic-inorganic hybrid materials based on Rhodamine 6G incorporated into a di-ureasil matrix. The experimental results, both in the spectral and temporal domains, obtained by pumping with picosecond laser pulses, show the existence of efficient random laser emission in this system. Finall...

With application to the impulse radio communications in mind, a locally supported and zero-mean pulse which is orthogonal to its shifts by integers is sought among the exponential splines having the knot interval 12 . An example pulse is obtained that complies with the regulation imposed by the US Federal Communications Commission and will potentially enable an impulse radio communications syst...

Single-stripe diode-laser-pumped operation of a continuous-wave 946-nm Nd:YAG laser with less than 10-mW threshold has been demonstrated. A slope efficiency of 16% near threshold was shown with a projected slope efficiency well above a threshold of 34% based on results under Rhodamine 6G dye-laser pumping. Nonlinear crystals for second-harmonic generation of this source were evaluated. KNbO(3) ...
