Hi thanks for your video,I have synthesized GO but after several time of washing and centrifuge the final ph is near 3 and doesn't change anymore, how can i reach ph 6?
I have a feeling that the conductive nature of it would short out the electrospinning process. Most/all electrospinning is done with nonconductive mostly insolating materials. If you are just after controlling the thickness use a drum to pull the extrusion through a bath. If you are after a tangled mess like electrospinning makes you could probably extrude through a mist using a ultrasonic humidifier or find a gas that acts like CaCL2 to cross polymerize. Though having a conductive large mass is generally not a good thing unless you are trying to make a ground plane.
Muy buen resultado. No se puede simplificar oxidando el grafito y luego reduciéndolo termicamente en horno???Digo yo que unas cuantas horas de lavados etc etc podriamos ahorrar no ??. Hay muchos oxidantes fuertes que en condiciones de presiôn adecuadas pueden separar las capas de grafito y este una vez oxidado pasarlo a estufa para separar las hipoteticas capas de grapheno que al final no son ùnicas si no que llevan varias capas de grapheno....
Hi bro, My opinion, this processor has no centrifuge, so it's much longer time than normally process, in Taiwan I knew Angstrom already have a massive scaled up product, the customer I supposed to be Mitsubishi and Tesla. 😉
Cihangir bey diz eklemlerinde kullanilan hidrogel in bir yan etkisi yada saglik icin risk varmi bu ayin sonunda Turkiyeye gelicem bunun icin lutfen beni bilgilendirirmisiniz bu konuda sonucta daha cok yeni bir tedavi biraz tedirginim cok tesekkurler
I am trying to prepare this hydrogel, without VSA. Here there is no mention of Nitrogen environment, which I frequently encounter while going through literature. It would be great if you can throw some light on it.
Merhaba hocam, İsmim Ferit ve tekstil öğretmeniyim. Manyetik kumaş ve grafen ile ilgili merak ettiğim sormak istediğim birkaç konu var. Mail yoluyla iletişime geçebilir miyiz lütfen? Yardımcı olursanız çok memnun olurum.
Hey! I know this is a weird question, but I need to make a grow-toy (lie the dinosaurs that grow in water) from scratch. I can't find any informatio on it other that it is made of "a mixture of sodium polyacrylate, polyvinyl acetate (a polymer used as a binder) and ethylene vinyl acetate". However, I have no idea how to make them. Could You please walk me through the process of making it from scratch? Is it even possible without a professional equipment?
Hi. Thank you for your video. I found some papers synthesis double network with acrylamide. They made the reaction under N2 protection. Is it important if we make the reaction without these conditions?
Thank you it was a really cool video, definitely I'm subscribing to your channel :), excuse me ¿Did the nanosize only achievable by the droplets that form during the emulsification process and the polymerization that occurs within or did you apply another agent to archive that size? also, how did you remove the residue of the surfactant applied?
I have two questions. 1. Can I use the membrane washing method right away without filtering through filter paper at 2:39? 2. It did not turn brown when refluxed like 2:00 and distilled water was added. Also, yellow gas was generated. Can you tell me the cause? Sulfuric acid used 95 percent. please answer 🙏
