Hydroxylation and hydroxylation graphene belong to functional graphene.Generally, graphite and alkali metal solids are milled continuously in a high energy ball mill, and graphene dispersed in water is treated with low frequency and high voltage pulse current. Hydroxyl-only water-soluble graphene can be obtained.

Vanadium is a malleable metal, but vanadium containing oxygen, nitrogen or hydrogen is brittle. Vanadium is a poor conductor of electricity and its conductivity is only one-tenth that of copper. At room temperature, fine vanadium is stable to oxygen, nitrogen and hydrogen. When heated in air, vanadium is oxidized to brown-black, blue-black vanadium tetroxide, or orange-red vanadium pentoxide. Under low temperature (180 ℃), the effect of vanadium and chlorine. Vanadium carbide and vanadium nitride were formed with carbon and nitrogen at high temperature.

what is Cadmium

Submitted by admin on Thu, 06/27/2019 - 02:13

Cadmium is a toxic element and its compounds are more toxic. It was meant to be a compound that didn't interact with human life, but the industrial revolution unleashed that demon. Some foreign studies have estimated that 22,000 tons of cadmium enters the soil every year. Cadmium compounds have different toxicity in nature. Cadmium sulphide and cadmium selenesulfonic acid were less toxic, cadmium oxide, cadmium chloride and cadmium sulfate were more toxic. The average dose of cadmium poisoning is 100mg.

Levothyroxine is used to treat hypothyroidism, when the thyroid gland does not produce enough thyroid hormone. It can also be used in surgery and radioactive iodine therapy to treat thyroid cancer. Levothyroxine is a class of drugs called hormones. Its job is to replace thyroid hormones normally produced by the body.
