Liquid-liquid extraction (LLE) is a separation technique used instead of distillation when either: (a) the relative volatilities of the compounds to be separated are very similar; (b) one or more of the mixture components are temperature sensitive even near ambient conditions; (c) the distillation would require a very low pressure or a very high distillate/feed...

Continuous Liquid-Liquid Extraction of Medium-Chain Fatty Acids from Fermentation Broth Using Hollow-Fiber Membranes

1.9K
A liquid-liquid extraction (LLE) system involving hollow-fiber membranes was developed to continuously and selectively extract medium-chain fatty acids (MCFAs) from the fermentation broth. The LLE system achieves high MCFA specificities from broths containing short-chain fatty acids and alcohols. Also, MCFAs are concentrated in a stripping solution to facilitate product recovery.

Extraction is a crucial step in most chemical analyses. It entails removing the analyte from its sample matrix and passing it into the phase required for spectroscopic or chromatographic identification and quantification. When the sample is a solid and the required phase for analysis is a liquid, the process is called solid-liquid extraction. A simple and broadly applicable form of solid-liquid extraction entails combining...

Microfluidic Preparation of Liquid Crystalline Elastomer Actuators

9.4K
This article describes the microfluidic process and parameters to prepare actuating particles from liquid crystalline elastomers. This process allows the preparation of actuating particles and the variation of their size and shape (from oblate to strongly prolate, core-shell, and Janus morphologies) as well as the magnitude of...

Liquidity Ratios: Current Ratio

309
Liquidity management involves strategically acquiring and using cash or near-cash resources, such as marketable securities, treasury bills, or short-term deposits, to ensure the company can meet its cash obligations as they come due.
The current ratio, calculated by dividing current assets by current liabilities, is a valuable tool for evaluating a company's liquidity.
Current assets are resources that can be quickly converted into cash, typically within a year. These include cash, cash...

Synthesis of Biocompatible Liquid Crystal Elastomer Foams as Cell Scaffolds for 3D Spatial Cell Cultures13:38

Synthesis of Biocompatible Liquid Crystal Elastomer Foams as Cell Scaffolds for 3D Spatial Cell Cultures

10.0K
This study presents a methodology to prepare 3D, biodegradable, foam-like cell scaffolds based on biocompatible side-chain liquid crystal elastomers (LCEs). Confocal microscopy experiments show that foam-like LCEs allow for cell attachment, proliferation, and the spontaneous alignment of C2C12s...
