    3D Graphene foam from glucose by chemical blowing

    I'd suggest that you would take a look at Dr Wang's recent papers. He has further optimized and examined the bubbling process. Of particular interest is his paper titled "High-throughput fabrication of strutted graphene by ammonium-assisted chemical blowing for high-performance supercapacitors"...

    3D Graphene foam from glucose by chemical blowing

    The synthesis of the grapheme foam is a one-step process from room temperature to 1350C with a temperature step of about 5C/min. It is important that it is performed in a inert atmosphere. A tube furnace is generally used for these purposes. However, the heating element, tube material and...

    3D Graphene foam from glucose by chemical blowing

    The pressure is 1 atm. There is nothing special about a tube furnace, but the fact that it is easy to create a specified atmosphere. This is really important since for the pyrolosis of carbon to take place, an inert gas is needed, otherwise the glucose will burn. According to their paper, 4C/min...

    3D Graphene foam from glucose by chemical blowing

    I'm a third year physics undergraduate and I want to make 3D Graphene - without spending a fortune. This is my background: I found this review article by Jiang and Fan (Design of advanced porous graphene materials: from graphene nanomesh to 3D architectures) to be very helpful. From what...

    Thomas Calculus 11th Ed: Thorough & Easy to Follow

    I had a look at both at the library, and I like the fact that Thomas' Calculus is in color, makes it a lot more interesting to read, even though Calculus: A Complete Course was more straight to the point with clearer explanations. I've asked, and I'm allowed to borrow Thomas' Calculus 9th...

    Thomas Calculus 11th Ed: Thorough & Easy to Follow

    Hello Could I ask which is better (Thomas' Calculus or Calculus : A Complete Course (Adams)). mathwonk says that there seems to be a lot of difference between the editions of Thomas' Calculus, and I need some guidance. I had created a topic but no one had replied...

    Can The Complete Idiot's Guide to Calculus Really Simplify Learning Calculus?

    Hello I am a physics student and for our first year we have a choice of 2 books for calculas: Thomas' Calculas 12th edition George B. Thomas Calculus : A Complete Course 7th edition Robert A. Adams Our teacher says that Thomas' Calculas is simpler, and Amazon reviews for the...
