- ... Recently, global attraction has shifted toward heavy unconventional crude oil due to the depletion of light oil resources. Generally, heavy crude oils are highly viscous in nature; due to this, their production and transportation are challenging. Asphaltenes and resins content directly affects the viscosity of crude oil. Many viscosity reducing agents affecting asphaltenes dispersion have been dev ...

- ... CO₂ absorption by liquid-containing amines to form carbamate and bicarbonates is an effective method of CO₂ mitigation from industrial exhausts, but this process is expensive and requires large quantities of amines. Here we modified chitosan, a naturally occurring biopolymer containing NH₂ functions, to use it for CO₂ absorption in aqueous media. Chitosan was dispersed in 40% aqueous NaOH solution ...
