PROBLEM TO BE SOLVED: To acquire an excellent graphene dispersion.SOLUTION: A container stores liquid comprising graphite and a dispersant, and grains having a grain diameter of 0.03-5 mm so that the grains are spread all over the bottom in the liquid. The liquid is then irradiated with ...
The video on how to make graphene at home is one of two videos (both shown below) explaining the amazing properties of the material. Hare has previously appeared on the BBC program Rough Science and now runs theCreative Science Centrein Sussex. How to make graphene with a pencil and sticky...
Graphene, a popular GraphQL library for Python, provides ISO-8601 formatted date-time values as a type native, so you don’t have to wrangle that yourself. If your data set has many fields, start by exposing the smallest functional subset of those fields that don’t require complex type ...
Graphene was expecting the .body attr but DRF reads it and attaches it to .data before being passed to GraphQLView. Can you explain to me exactly what happening here and why I need to do it? It works for me but I'm not certain as to why. Originally I was also getting the You ca...
I'm trying to upload a file to a django backend using graphene-file-upload which has the mutation to link the backend to the react frontend where I'm trying to use apollo-upload client to link it with graphql. In my django model an empty file is being successfully...

This assumes you already have the zip file of the GrapheneDB database. The goal here is to import this as an entire database, not to pull the data from it…
involving graphene have been introduced in the literature, however, graphene is either a functional add-on to resonators made from metals with a high electrical conductivity, or it is studied as arrays of relatively simple plasmonic stripes or disks, made from single- or multi-layer graphene. Gr...
(PhysOrg.com) -- In a video that communicates science achievements to people of all backgrounds, physicist and TV presenter Jonathan Hare explains how to make graphene from a graphite pencil and a piece of Scotch tape. The simple experiment shows how, in
Graphene, a two-dimensional structure made of carbon, is a material with excellent mechanical, electronic and optical properties. However, it did not seem suitable for magnetic applications. Together with international partners, Empa researchers have now
