Watermarking embeds information into a digital signal like audio, image, or video. Reversible image watermarking can restore the original without any distortion after hidden data is extracted. In this paper, we present novel reversible scheme using an interpolation technique, which embed large amount of covert images with imperceptible modification. Different from previous schemes, utilize interpolation-error, difference between value and corresponding pixel value, to bit ¿1¿ ¿0¿ by...
Abstract This review gives first a brief view of the potential availability sustainable energy. It is clear that over 100 times more solar photovoltaic energy than necessary readily accessible and practically available wind alone may deliver sufficient supply to world. Due intermittency these sources, effective inexpensive energy-conversion storage technology needed. Motivation for possible electrolysis application reversible solid-oxide cells (RSOCs), including comparison...
Abstract Severe degradation of Ni‐YSZ (yttria stabilized zirconia) electrodes solid oxide cells (SOCs) due to Ni migration is well known, but the literature contains apparent contradictions. The mechanisms are still under debate. Fine structured composite often degrade at operation temperature (700–950°C), because particles lose electrical contact with each other as larger Ni‐particles grow on expense smaller ones. Another type migration, which may be very damaging, relocation in most active...
Green hydrogen by solid oxide electrolyzer (SOEC) will become cheaper than gray hydrogen. The Levelized Cost of Hydrogen (LCOH) be reduced heat integration, super grid and SOEC development.
The Danish government plans two energy islands to collect offshore wind power for distribution and green fuel production. Wind is often criticized lacking stability, which challenges downstream synthesis processes. Solid oxide electrolysis cells (SOEC) are promising hydrogen production on a commercial scale, but the impact of fluctuating SOEC remains uncertain. This paper explores feasibility Wind-SOEC coupled system by conducting 2104-h durability test with state-of-the-art Topsoe TSP-1...
Abstract Development of new aggregation‐induced emission (AIE) luminogens has been a hot research topic because they thoroughly solve the notorious aggregation‐caused quenching effect confronted in conventional fluorogens and their promising applications in, for example, organic light‐emitting diodes, chemo‐ biosensors bioimaging. Many AIE (AIEgens) have prepared but most them are silole, tetraphenylethene, distyrylanthracene, derivatives. In this work, based on skeleton tetraphenylpyrazine...
Ni/yttria stabilized zirconia (YSZ) supported solid oxide electrolysis cells (SOECs) were exposed to long-term galvanostatic tests, under different testing conditions (temperature, gas composition, current density etc.) with an emphasis on high (above −1 A/cm2). Detailed post-mortem characterizations carried out investigate microstructural changes after focusing the Ni/YSZ electrode. Formation of ZrO2 nano-particles Ni surfaces was observed in or −1.5 A/cm2 at 800 850°C, but not those tested...
Power-to-fuel systems via solid-oxide electrolysis are promising for storing excess renewable electricity by efficient of steam (or co-electrolysis and CO2) into hydrogen syngas), which can be further converted synthetic fuels with plant-wise thermal integration. Electrolysis stack performance durability determine the system design, performance, long-term operating strategy; thus, electrolyzer based power-to-fuels were investigated from to levels. At level, data a 6000-h testing under...
Abstract This paper deals with degradation mechanisms of Ni–YSZ electrodes for solid oxide cells, mainly electrolysis cells (SOECs), but also to some extent fuel (SOFCs). Analysis literature data reveals that several apparently different and even in one case contradicting phenomena are a consequence interplay between loss contact the (and Ni–Ni particles) active fine‐structured composite electrode layer migration Ni via weakly oxidized hydroxide species. A hypothesis unravels apparent...
Despite various advantages of high-temperature solid oxide electrolysis cells (SOECs) over their low-temperature competitors, the insufficient long-term durability has prevented commercialization SOECs. Here, we address this challenge by employing two nanoengineered electrodes. The O2 electrode consists a La0.6Sr0.4CoO3-δ (LSC) and Gd,Pr-co-doped CeO2 (CGPO) nanocomposite coating deposited on Gd-doped (CGO) scaffold, H2 comprises Ni/yttria stabilized zirconia (YSZ) modified with nanogranular...
This paper investigates the problem of secure energy efficiency maximization for a reconfigurable intelligent surface (RIS) assisted uplink wireless communication system, where an unmanned aerial vehicle (UAV) equipped with RIS works as mobile relay between base station (BS) and group users. We focus on maximizing system via jointly optimizing UAV's trajectory, RIS's phase shift, users' association transmit power. To tackle this problem, we divide original into three sub-problems, propose...
