A broadband metamaterial absorber (MA) composed of hexagonal-arranged single-sized titanium nitride (TiN) nano-disk array and monolayer molybdenum disulfide (MoS2) is studied using finite-difference time-domain (FDTD) simulations. The structure of TiN nano-disk array/dielectric silica (SiO2)/aluminum (Al) is adopted in our design. By optimizing the dimension parameters of the structure, an aver...

During the last decade, major efforts have been made to develop adequate and commercially viable processes for disintegrating cellulose fibres into their structural components. Homogenisation of cellulose fibres has been one of the principal applied procedures. Homogenisation has produced materials which may be inhomogeneous, containing fibres, fibres fragments, fibrillar fines and nanofibrils....

ZnO nano-particles with a diameter of 10-20 nm were fabricated under oxygen and helium mixture plasma circumstance by evaporating Zn target using pulsed laser ablation. Cathodoluminescence technique, combined with transmission electron microscopy, X-ray diffraction and energy-dispersive spectrometer, was applied to study luminescence property and crystalline structure of ZnO nano-particles. Var...

Pores of shale exhibit multiscale characteristics, and pore characterization is challenging due to the complexity systems. Currently, research focused on nano-submicron pores, but structure micrometer-scaled pores not well understood. In this research, an investigation three-dimensional network Chang 7 in Ordos Basin China was conducted, order provide insight into full characteristics Nano-CT m...

Cerium oxide nanoparticles (nano-CeO₂) have been reported to cause damage and apoptosis in human primary hepatocytes. Here, we compared the toxicity of three types of nano-CeO₂ with different nanocrystal morphologies (cube-, octahedron-, and rod-like crystals) in human hepatocellular carcinoma cells (HepG2). The cells were treated with the nano-CeO₂ at various concentrations (6.25, 12.5, 25, 50...

The nano-domain, with short-range ordered structure, has been widely observed in rare-earth-doped ceria. Atomistic simulation has been employed to investigate the ordering structure of the nano-domain, as a result of aggregation and segregation of dopant cations and the associated oxygen vacancies in gadolinium-doped ceria. It is found that the binding energy of defect cluster increases as a fu...

  Magnesium and its alloys are light, biodegradable, biocompatible metals that have promising applications as biomaterials. Magnesium is potentially useful for orthopedic and cardiovascular applications. However, the corrosion rate of this metal is so high that its degradation occurs before the end of the healing process. One of the ways to improve the corrosion rate is to compose it’s with cer...
