Hemoglycin, a 1494 Da polymer composed of iron and glycine has been detected in several carbonaceous meteorites. Iron atoms close out the ends of a 5nm anti-parallel glycine beta sheet and contribute visible and near infrared absorptions that are not present with glycine alone. The 483nm absorption of hemoglycin was discovered in theory and then ob...

The MicroCrys platform was developed to automate on-chip dialysis crystallization of proteins via chemical composition and temperature control, facilitating the optimization of crystallization conditions and the exploration of protein phase diagrams.

A microfluidic chip has been developed coupling the advantages of the microfluidic technology and the microdialysis protein crystallization method allowing for accurate, fine-tuned and reversible control over the experimental parameters of the on chip crystallization. Microchips with 0.1 µL and 0.3 µL maximum volume of the protein reservoir have be...

This protocol describes the manufacturing of reproducible and inexpensive microfluidic devices covering the whole pipeline for crystallizing proteins on-chip with the dialysis method and allowing in situ single-crystal or serial crystallography experiments at room temperature. The protocol details the fabrication process of the microchips, the mani...

This paper reports a versatile microfluidic chip developed for on-chip crystallization of proteins through the dialysis method and in situ X-ray diffraction experiments. A microfabrication process enabling the integration of regenerated cellulose dialysis membranes between two layers of the microchip is thoroughly described. We also describe a rati...

BACKGROUND In the present work, a combination of several physicochemical methods has been applied aiming at recovering phosphorus from olive mill wastewater (OMW) in the form of struvite (NH 4 MgPO 4 ·6H 2 O, MAP) and at the same time achieving reduction of the chemical oxygen demand (COD) of the wastes. Phosphorus is a valuable raw material used f...

The precipitation and crystal growth of sparingly soluble salts is associated with scaling problems in oil and gas extraction processes. The presence of oleic phases and/or organic solvents added as inhibitors of the gas hydrates often complicates scale formation problems. The pore structure of the oil reservoir walls is of particular interest in t...

Visualization experiments using one-dimensional (1-D) porous media made of Plexiglas and two-dimensional glass porous networks were conducted to obtain qualitative and quantitative information concerning the precipitation and crystal growth of CaCO3 under varying flow and concentration conditions. Supersaturated solutions were prepared by mixing so...

The deposition of salts in porous media is a major engineering phenomenon encountered in a plethora of industrial and environmental applications where in some cases is desirable and in other not (oil production, geothermal systems, soil stabilization etc). Systematic approach of these problems requires knowledge of the key mechanisms of precipitati...

The deposition of sparingly soluble salts (scaling) within porous media is a major problem encountered in many industrial and environmental applications. In the oil industry scaling causes severe operational malfunctions and, therefore, increasing the total operating and maintenance cost [1]. The most common types of sparingly soluble salts located...

The deposition of sparingly soluble salts (scaling) within porous media is a major problem encountered in many industrial and environmental applications, such as oil industry. The main purpose of the present work was the investigation of the precipitation mechanisms of calcium carbonate (CaCO 3) after in situ mixing of two soluble salt solutions un...
