OF THE
TIMES
It's to late. Just let them carry on and commit a drawn out suicide if that's what they want. If people are still willing to take part in all this then let them have that Darwin Award they're going after.I am hoping for a corner room in Wellingborough, do ya think we'll be allowed to compete in an inter-prison football tournament or the likes?
I'll take my chances in covid camp. See all you UK SOTTites at HMP Five Wells in the next year or two
It's very hard to be for freedom of choice when people seem to want to murder their children.I consider all of this as some kind of IQ test. Smart ones will survive. Others...
I am not an academic or a scholar, I have an inquisitive mind and a brain stuck in critical gear.I recently came to the conclusion that both are mutually exclusive in our Western society.
I would like to know how GO is chelated.
GO Synthesis and Characterization [Link]
GO sheets were synthesized according to the modified Hummers’ method as previously described.32 The synthesis was performed under endotoxin-free conditions with a laminar flow hood, water for injection, gloves, non-pyrogenic plastic containers, and depyrogenated glassware.34 In brief, 0.8 g of graphite flakes (Graflake 9580) obtained from Nacional Grafite (Brazil) were mixed with 0.4 g of sodium nitrate in a round bottom flask, and then 18.4 mL of sulfuric acid 99.999% was added slowly to the mixture. After obtaining a homogenized mixture, 2.4 g of potassium permanganate was slowly added, and the mixture was maintained for 30min; 37mL of water for injection was added drop-wise because of the violent exothermic reaction, and the temperature was continuously monitored and kept at 98C for 30 min. The mixture was further diluted with 112 mL of water for injection, and 30% hydrogen peroxide was added for the reduction of the residual potassium permanganate, manganese dioxide, and manganese heptoxide to soluble manganese sulfate salts. The resulting mixture was purified by several centrifugation steps at 9,000 rpm for 20 min until a viscous orange/brown layer of pure GO started appearing on top of the oxidation by-products at pH 6. This GO gel-like layer was extracted carefully with warm water, resulting in large GO (GO-L). Final concentrations ranging between 1 and 2 mg/mL were obtained with a yield of approx. 10%. GO-L was freeze dried, reconstituted in water for injection, sonicated in a bath sonicator (VWR, 80W) for 5 min, and centrifuged at 13,000 rpm for 5 min at room temperature to prepare small GO(GO-S). The GO samples have been shown to remain stable for more than 1 year. In the present study, all GO samples were used within 1 year of their production.
The samples were stored in darkness until experimental use because GO can undergo photo-reduction in sunlight.
" . . . thought it was just some type of inert metal"
Graphene is an allotrope [Link] of carbon consisting of a single layer of atoms arranged in a two-dimensional honeycomb lattice.[Something a single atom thick is here considered to be "two dimensional" Then we have "bilayer graphene" discussed here [Link] where in the opening sentence they overlook the fact that in 1924 J.D. Beranl presented a paper to the Royal Society in the UK called, "The Structure of Graphite". The paper is seen on PDF page (16 of 170) on my site here [Link] ].
The name is a portmanteau of "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon consists of stacked graphene layersNothing about the name reflects anything; but yes, graphite does consist of stacked layers of graphene, quite like a deck of cards.
I've seen the chemical arrangement, it's very strong too.Each "card" in the deck (each layer of graphene) is very strong in-plane, but the "cards" only stick together with only about 1/7000th the strength of an individual "card" pulled to try to make it, say, longer.
