For the amine transaminase (ATA)-catalyzed synthesis of chiral amines, the choice of donor substrate is of high importance for reaction and process design. Alanine was investigated as an amine donor for the reductive amination of a poorly water-soluble ketone (4-phenyl-2-butanone) in a combined in situ product removal (ISPR) approach using liquid-membrane extraction together with an enzyme cascade

Hemicelluloses with high molecular mass are needed for the manufacture of value added products such as food packaging barrier films. In this work such molecules were recovered from chemithermomechanical pulp (CTMP) process water using an innovative three-stage process comprising membrane separation and enzymatic treatment with laccase. Microfiltration followed by ultrafiltration was found to be a

This study investigates several commercial selective catalytic reduction (SCR) catalysts (A–E) for application in a high-temperature (approximately 525 °C) and high-concentration (5000 ppm NO) system in combination with CO2 capture. The suggested process for removing high concentrations of NOx seems plausible and autothermal operation is possible for very high NO concentrations. A key property of

Popular Abstract in Swedish Rehabilitering av personer med långvariga psykiska sjukdomar, i synnerhet psykossjukdomar har fått ett ökat intresse i samband med de långtgående omstruktureringarna av den psykiatriska vården i riktning mot samhällsbaserade vårdformer. Psykiska sjukdomar är många gånger mycket allvarliga och kan leda till ett långvarigt lidande och svåra handikapp. Det har också visat All patients admitted during a four-year period to a comprehensive, cognitive therapy based inpatient rehabilitation program for long-term mentally ill were invited to participate in the present study. A total of 28 patients were included. The patients were at admission and discharge assessed with regard to quality of life, symptoms, global functioning and target complaints. Every five weeks throu

For the design of a new separation process based on unfolding and refolding of protein, the partitioning behaviour of proteins was studied in thermoseparating polymer two-phase systems with varying pH and temperature. Chymotrypsin inhibitor 2 (CI2), which unfolds reversibly in a simple two-state manner, was partitioned in an aqueous two-phase system (ATPS) composed of a random copolymer of ethylen

In this paper results are presented from a range of experiments to explore the feasibility of inserting a ceramic material PZT (lead zirconium titanate) into different kinds of high-aspect-ratio resist moulds. Polymethylmethacrylate (PMMA) and SU-8 on silicon substrates and free-standing SU-8 membranes with microcavities or through-holes (defined by X-ray lithography) have been used as moulding me

SiGe Esaki diodes have been realized by rapid thermal diffusion of phosphorous into an SiGe layer grown by ultra-high-vacuum chemical-vapor-deposition on an Si p(+)-substrate for the first time. The phosphorous-doped SiGe forms the n(+)-electrode, while heavily boron-doped Si0.74Ge0.26 and Si substrate is used for the p(+) electrode. The diodes show a peak current density of 0.18 kA/cm(2), a curre

An economically sustainable process was developed for propionic acid production by fermentation of glycerol using Propionibacterium acidipropionici and potato juice, a by-product of starch processing, as a nitrogen/vitamin source. The fermentation was done as high-cell-density sequential batches with cell recycle. Propionic acid production and glycerol consumption rates were dependent on initial b
