From drug development and DNA sequencing to high throughput PCR testing, automated liquid handling has revolutionised the way modern laboratories operate. Click to read more...
It is a liquid-liquid extraction process used to purify and concentrate solutions obtained from the leaching of ores. Solvent extraction acts as a purification and concentration technique at the same time. What is the unique feature of hydrometallurgy? The more general characteristics of ...
In most cases, the substance to be extracted, which may be a solid, a liquid or a gas, is dissolved in a liquid, along with other substances, and a liquid solvent is used for the extraction — this is sometimes called liquid-liquid extraction. The technique may also be applied to ...
Liquid–liquid extraction (LLE) is based on the principle that a solute or an analyte can distribute itself in a certain ratio between two immiscible solvents, usually water (aqueous phase) and organic solvent (organic phase). What is age hardening? Age hardening, also known as precipitation ha...
作者: Johnson,Keith,E. 展开 摘要: The article presents information on ionic liquids. The term ionic liquids was introduced to cover systems below 100°C. The properties of a modern ionic liquid include low vapor pressures and moderate specific conductivities. The molarity of the liquid is impor...
What is fractional distillation? Write its definition and process. Fractional Distillation: There are a number of types of distillation. The most common one is the simple distillation and the fractional distillation. This is marked with liquid conversion to vapor conversion. Answer and Explanation: ...

What does an ionic liquid surface really look like? Unprecedented details from molecular simulations We present the first intrinsic analysis of the surface of the [bmim][PF6] room-temperature ionic liquid. Our detailed analysis reveals unprecedented detail......
Crude oil is a naturally occurring liquid petroleum product composed of hydrocarbon deposits and other organic materials formed from the remains of animals and plants that lived millions of years ago. These organisms were covered by layers of sand, silt, and rock, subject to heat and pressure, ...
