The radiolarian chert rocks are one of the most important indications of the existence of ophiolites because they are a source of silica supply.These rocks have been studied to refute and reject the idea that ophiolites do not existed.The Si/(Si+Al+Fe+Ca) ratio in the radiolarian chert indicates that the silica is of biogenic origin and adds SiO2 f

Abstract Background Pepper mild mottle virus (PMMoV) is a member in the genus Tobamovirus and infects mainly solanaceous plants.However, the mechanism of virus-host interactions remains unclear.To explore the responses of pepper plants to PMMoV infection, we analyzed the transcriptomic changes in pepper plants after PMMoV infection using a high-thr
In this work, we investigate by ab initio calculations and optical experiments the sensitivity of graphene quantum dots in their use as devices to measure the presence, and concentration, of heavy metals in water.We demonstrate that the quenching or enhancement in mrf53ll/a the optical response (absorption, emission) depends on the metallic ion con
