In order to reduce considerable emissions of N-containing pollutants from combustion sewage sludge derived solid fuel, an integrated system hydrothermal deamination and air stripping was developed effectively remove recover nitrogen dewatered (DSS). Three characteristic regimes contributing were identified. Initial hydrolysis inorganic-N labile protein-N responsible for ammonium (NH4+-N) released below 300 °C/9.3 MPa, whereas pyridine-N dominated when being raised 340 °C/15.5 MPa. At 380 °C...
Abstract The interior of the synthetic unit cells and their interactions determine wave properties metamaterials composed periodic lattices these cells. While local with nearest neighbors are well appreciated, nonlocal beyond-nearest-neighbor often considered as a nuisance. Here, by introducing versatile effectively two-dimensional metamaterial platform for airborne sound elastic waves, we exploit effects powerful design tool. Within simplified discrete model, analytically show that lowest...
Metamaterials are artificial materials in which the atoms of ordinary solids replaced by tailored functional building blocks. Therefore, previous work has emphasized tailoring inside blocks, for example, exploiting local resonances, to realize unusual effective metamaterial properties. However, wave properties a not only determined its blocks but also interactions between these Here, reconfigurable "plug-and-play" electromagnetic metamaterials introduced essentially trivial standard bayonet...
Abstract Previous theory and experiment has shown that introducing strong (nonlocal) beyond-nearest-neighbor interactions in addition to (local) nearest-neighbor into rationally designed periodic lattices called metamaterials can lead unusual wave dispersion relations of the lowest band. For roton-like dispersions, this especially includes possibility multiple solutions for wavenumber at a given frequency. Here, we study one-dimensional frequency-dependent acoustical phonon transmission slab...
Chrome-containing waste is the major stumbling block for leather industry. However, in current manufacturing, chrome tanning difficult to replace due excellent characteristics it endows on finished and because Cr agents play a key role tanning. To reduce increasing serious pollution, this study establishes Cr-wastewater loop system (CL system) reuse effluents through high-basicity chromium agent adjusting, mechanisms of with different basicities affecting CL were explored. The basicity...
Abstract A theoretical paper based on chiral micropolar effective‐medium theory suggested the possibility of unusual roton‐like acoustical‐phonon dispersion relations in 3D elastic materials. Here, as a first novelty, corresponding inverse problem is solved, that is, specific metamaterial structure designed, behavior which follows this description. The simple‐cubic lattice cubes, each not only has three translational but also rotational degrees freedom. additional freedom are crucial within...
Abstract Ohm's law of electric conduction is local in the sense that current density at one position only depends on field same position. For a nonlocal medium, other positions within medium as well. As result law, doubling length wire doubles its resistance. Here, electrically conducting architectures are discussed theoretically and experimentally for which changing metawire rather leads to complex oscillatory behavior versus length. This connected currents inside flowing opposite direction...
In the absence of prior drying, dewatered sewage sludge (DSS) was directly converted to hydrochars with superior fuel characteristics in subcritical water. Hydrochar derived at 320 °C and 12.0 MPa (SHC-320) screened for systematic cocombustion different-rank coals. The results suggest that SHC-320 reduced activation energy blends altered main combustion profiles. Meanwhile, blending induced greater heat loss higher-rank coals, whereas a higher portion further improved ignition reactivity...
