In this work, we developed a green and efficient process for the recovery of rare earths from waste cathode ray tube phosphors. The mixture hydrochloric acid hydrogen peroxide was identified as most suitable leaching agent due to synergistic effect. effects various parameters on were explored, optimal conditions with stirring speed 600 rpm, temperature 313 K, 1 M H2O2, 4 HCl, time 90 min determined. Furthermore, possible reaction mechanism proposed, kinetics investigated in detail. found...
Organic–inorganic hybrid solar cells based on n-type crystalline silicon and poly(3,4-ethylenedioxythiophene)–poly(styrenesulfonate) exhibited promising efficiency along with a low-cost fabrication process. In this work, ultrathin flexible substrates, thickness as low tens of micrometers, were employed to fabricate reduce the use materials. To improve light-trapping ability, nanostructures built thin substrates by metal-assisted chemical etching method (MACE). However, nanostructured...
Hemispherical resonator gyroscope (HRG) is a high precision inertial sensor for measurement of rate and attitude angle, the fused silica hemispherical key component HRG which ultra-low frequency split required. During entire fabrication process resonator, imperfects resonators should be trimmed by evaluating quality-factor in real-time. Therefore, high-precision balance method based on synchronous trimming system has been proposed this paper, quality-factor, principle-axis angle could...
In this paper, we propose a novel and sustainable process for recycling rare earths (REs) zinc (Zn) simultaneously from waste cathode ray tube (CRT) phosphors. First, 95% of the impurities such as glass cullets aluminum foils are removed by simple screening. Then, self-propagating, high-temperature synthesis reaction following water-leaching is performed to recycle Zn selectively. The REs recycled combined oxidative leaching ionic-liquid-based extraction. They then regenerated form new...
In dense radio frequency identification (RFID) systems, the tag collision arbitration is an important issue for fast identification. this paper, we propose a novel transmission control algorithm RFID systems based on framed slotted ALOHA (FSA) where number of tags assumed unknown in advance. The considered combines lower bound estimation with new grouping strategy, and uses ratio factor to algorithm. proposed approach maximizes system efficiency while keeping moderate time reading tags....
This study presents a near-field beamforming method for the moving swarm composed of unmanned aerial vehicles (UAVs) to address challenges position errors that hinder effective beamforming. Firstly, model with positional in UAVs was developed. The sources and characteristics UAVs’ were analyzed classified into low-frequency motion high-frequency vibration errors, their effects on array using coordinate transformation decomposition. Secondly, parameter estimation algorithm proposed based Fast...
