Tailorable microwave absorption characteristics of bio waste-based composites through a macroscopic design

a study on the design of bio-ethanol process from date wastes of sistan and baluchistan province

اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...

Microwave Absorption and Infrared Stealth Characteristics of Bamboo Charcoal/Silver Composites Prepared by Chemical Reduction Method

Bamboo charcoal coated with silver (BC/Ag) was prepared by activation and chemical reduction processes at different AgNO3 contents (10-30 wt.%). The spectroscopic characterizations of the formation processes of BC/Ag composites were studied using X-ray diffraction, scanning electron microscopy and transmission electron microscopy. These composites were introduced in epoxy resin to be a microwav...

Optimisation of microwave absorption of carbon nanotube composites through use of carboxyl-epoxide functional group linkages

Lightweight, flexible and highly efficient microwave absorbing singlewalled carbon nanotube (SWNT)/polymer composites were fabricated through chemical functionalisation to ensure uniform dispersion of SWNTs in a polymer matrix. These composites were used to fabricate thin electromagnetic absorption coatings, which achieve a maximum reflection loss (RL) magnitude of 24 dB at X-band frequencies. ...

Microwave Characterization of Bio-composites Materials Based Finite Element and Nicholson–ross–weir Methods

In this work, Bio-composite of oil palm empty fruit bunch fibre (OPEFB)-filler and polycaprolactone (PCL)-polymer has been prepared and characterized. The functional groups and morphology of the prepared samples were characterized by Fourier transform infrared spectroscopy (FT-IR). By using the NicholsonRoss-Weir (NRW) mode, both of real and imaginary relative permittivity values of the samples...
