Synthesis of Mn3O4-Based Aerogels and Their Lithium-Storage Abilities

Mn3O4 aerogels and their graphene nanosheet (GN) composite aerogels were synthesized by a simple supercritical-ethanol process. In the process, supercritical ethanol acted as a reductant to reduce graphene oxide and MnO2 gels simultaneously. The synthesized aerogels consisted of 10-20 nm Mn3O4 nanocrystallites, with BET-specific surface areas around 60 m(2)/g. The performance of the aerogels as...

Synthesis and textural characteristics of organic aerogels, transition-metal-containing organic aerogels and their carbonized derivatives

Four organic aerogels were prepared by the sol-gel method from polymerization of resorcinol with formaldehyde catalyzed by Na CO . These aerogels were further pyrolyzed in N in order to obtain their corresponding carbon aerogels, 2 3 2 and after that activated with either steam or CO to obtain activated carbon aerogels. Another series of organic aerogels and 2 their pyrolyzed and activated deri...

امروزه مسئله ی اساسی در رویکرد های جدید زبانشناسی، ابعاد اجتماعی و ایدئولوژیک زبان تلقی می شود. گروه های مختلف اجتماعی، سیاسی و یا مذهبی از زبان به عنوان ابزاری برای دستیابی به اهداف درون گروهی خود استفاده می کنند (ون دایک، 2003). آنها معولا ایدئولوژی خود را صریحا ابراز نمی کنند بلکه آن را در غالب کلمات و ساختارهای زبانی پنهان نگه می دارند. تشخیص ایدئولوژی های پنهان در گفتمان نیازمند این موضوع ...
