A Review of routing protocols for mobile cognitive radio ad hoc networks [PDF]

arXiv, 2012
Ad hoc network is a collection of wireless mobile nodes that dynamically form a temporary network without the use of any existing network infrastructure or centralized administration. A cognitive radio is a radio that can change its transmitter parameters based on interaction with the environment in which it operates.

Rational Engineering of Nanostructured AgM (M = Au, Pt, Pd) Bimetallic Electrodes via Galvanic Replacement for Glycerol Electrolysis

Advanced Engineering Materials, EarlyView.
This study demonstrates the feasibility of fabricating free‐standing carbon paper electrodes by electroplating and galvanic replacement. Nanostructured AgM (M = Au, Pt, Pd) bimetallic catalysts are directly grown on the electrode substrate, which exhibit good performance for glycerol electrolysis, a sustainable approach for the co‐production of green ...

Covalently‐Bonded Diaphite Nanoplatelet with Engineered Electronic Properties of Diamond

Advanced Functional Materials, EarlyView.
A novel approach to engineering the electronic properties of diamond is reported on the diaphite nanoplatelet consisting of (11¯${{\bar{1}}}$1) planes of diamond nanoplatelet covalently bonded with graphite (0001) planes. The strong sp3/sp2‐hybridized interfacial covalent bonding induces the electron transfer from diamond to graphite, resulting in a ...
