Extraction and separation of proteins is important for their interesting applications as continuous enzymatic reaction and/or product separation systems. In this work, a new highly efficient homogeneous capture and heterogeneous liquid–liquid separation strategy is presented for the extraction of proteins from aqueous solution by PEG (poly(ethylene glycol))-functionalized ionic liquids, which h...

Both water soluble lysine- and aspartic acid-based amino acid ionic liquids (AAILs) were mixed to prepare polar AAILs showing phase separation with water.

The climatological current field off the coast of New South Wales, Australia, is investigated using results from a field experiment and a diagnostic, numerical modeling study. In particular, the flow dynamics are examined near Smoky Cape (308559S) in the vicinity of the East Australian Current separation point. Modeled velocity fields compare favorably with observed velocity measurements that w...

After our studies on the distribution of water, nitrogen and electrolytes in the whole skin, it was thought that the different layers of the skin should be investigated separately. The epidermis was therefore separated from the corium and the nitrogen and electrolyte distribution was determined in each of the layers In view of the fact that adequate literature on the methods for the separation ...

A simple and fast method to prepare robust superhydrophobic octadecylphosphonic acid (ODPA) coating on oxidized copper mesh for self-cleaning and oil/water separation is reported here. The substrate of the copper mesh was first oxidized by simple immersion in an aqueous solution of 1.0 M NaOH and 0.05 M K2S2O8 at room temperature for 30 min, which was then covered with micro- and nanoscale Cu(O...

Membrane separation is known as an efficient technique for the oily wastewater treatment. Therefore, in the present study, sulfonated poly (ether ether ketone) (SPEEK) was introduced into the polysulfone (PSF) solution in order to enhance the hydrophilicity and the membrane structure for the oil–water separation. The hollow fiber membranes were fabricated via a phase-inversion process. The memb...

introduction: detection of cryptosporidium and giardia parasites in water samples is usually performed by us environmental protection agency 1623 method. nevertheless, the usepa1623 method still need improvement, to prevent and control the water borne parasitic disease. therefore, we undertook the present study. materials and methods: totally 48 surface water samples were collected. four sample...
