We have successfully prepared nanohybrids of biofunctional ferulic acid and layered double hydroxide nanomaterials through reconstruction and exfoliation-reassembly routes. From X-ray diffraction and infrared spectroscopy, both nanohybrids were determined to incorporate ferulic acid molecules in anionic form. Microscopic results showed that the nanohybrids had average particle size of 150 nm wi...
In this paper a numerical model to study the vibro-acoustic behavior of a laminated plate backed by a poroelastic foam layer is developed. Such approach consists on a coupled mitigation strategy aiming either mechanical vibration suppression or acoustic attenuation as well. The laminated plate model consists of fiber laminae with interleaved viscoelastic layers in standard constrained or integr...
Madal performance is the basic characteristics of structures, which will help to further understand vibration structures. Besides, fluid (e.g. water) coupled with structure strongly affact modal structure. To get clear performance, Modal tests are conducted for two-layered plate both in air and water, frequency mode shape given. With comparative analysis frequencies these two cases, it’s shown ...
Abstract Multi-layered composite shells are extensively used in many industrial fields since they have superior performance applications. As load-carrying components, buckling failure is one of the most common modes multi-layered shells. Hence, layup design based on optimal factors widely concerned, where lamination parameters commonly representation stiffness. However, formulations laminate st...
Abstract A mathematical model for nonlocal vibration and buckling of embedded two-dimensional (2D) decagonal quasicrystal (QC) layered nanoplates is proposed. The Pasternak-type foundation used to simulate the interaction between elastic medium. exact solutions frequency critical load 2D QC are obtained by solving eigensystem using propagator matrix method. present three-dimensional (3D) soluti...
Property and Personality Rights with Regard to Biobanks: A Layered System with Germany as an Example
In the field of genetic research and the subsequent rise of biobanks an intensive discussion is taking place on national and international levels about property and personality rights to one’s own body and body parts. The authors attempt to develop on the basis of the current controversially discussed law a concept of property, which can solve the legal and bioethical problems of the multiple u...
An all-metallic multi-layered parallel-plate slot array antenna operated in the 60-GHz band with wide impedance bandwidth and high-gain characteristics is proposed. The $16\,{\times }\,16$ -slot composed of notation="LaTeX">$2\,{\time...
