Preparation of a Lignin-based Composite and Its Properties

Enzymatic hydrolysis (EH) lignin was modified with formaldehyde. TGDSC and PY-GC-MS analysis methods were adopted to characterize the differences between EH lignin and the modified lignin. The modified lignin was then mixed with wood sawdust and made into a lignin-based composite under the following conditions: pressure of 2 to 5 MPa, temperature of 175 to 190 C, and the modified lignin dosage ...

Progress in Research and Application of Silymarin

Silymarin (SL), a mixture of flavonolignans mainly including silybin A and B, isosilybin A and B, silidianin, and silychristine from the seeds of Silybum marianum L., has been widely used to treat acute and chronic viral hepatitis, toxin/drug-induced hepatitis, cirrhosis, alcoholic fatty liver diseases and other ailments because of its excellent hepatoprotective effect. Silybin is the most acti...

Progress of Membrane Engineering for Water Treatment

Together with the supply of energy and the environmental protection, fresh water is one of the three keys elements for the sustainable development of every society. Where the availability of water cannot be carried out by using conventional sources, unavoidable appears the resort of the major water source: the sea. Today, RO is one the most used membrane processes for the production of fresh wa...
