Modern Nanocomposites and Hybrids as Electrode Materials Used in Energy Carriers

Nanostructured MnO2 as Electrode Materials for Energy Storage

Manganese dioxides, inorganic materials which have been used in industry for more than a century, now find great renewal of interest for storage and conversion of energy applications. In this review article, we report the properties of MnO₂ nanomaterials with different morphologies. Techniques used for the synthesis, structural, physical properties, and electrochemical performances of periodic ...

Liposomes as carriers for DNA-PNA hybrids.

Peptide nucleic acids (PNAs) are DNA mimics composed of N-(2-aminoethyl)glycine units. This structure gives to PNAs (a) resistance to DNases and proteinases, (b) capacity to hybridize with high affinity to complementary sequences of single-stranded RNA and DNA, and (c) capacity to form highly stable (PNA)(2)-RNA triplexes with RNA targets. Furthermore, DNA-PNA hybrid molecules are capable to re...

Polymer-Silver Nanocomposites as Antibacterial materials

The antibacterial effect of silver has been used in a variety of commercially available products and medical devices for many years, either in its metallic or salt form. Nowadays, due to the knowledge acquired within the last decade in the field of Nanoscience and Nanotechnology, the use of silver nanoparticles (AgNPs) for medical and sanitary purposes has been thoroughly studied and dramatical...

economic optimization and energy consumption in tray dryers

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...
