The behavior of amines in various CO 2 -rich solvents is described. 1 H and 13 C NMR spectra in DMSO, chloroform, and benzene show that the amines are completely converted into carbamic acid by just bubbling atmospheric CO 2 through the solution. How

The use of solvent resistant nanofiltration (SRNF) provides an elegant alternative to the classical heterogenization of homogeneous catalysts. The SRNF-membrane separates the catalyst from the reaction mixture and allows products and solvent to perme

Supercritical Water Oxidation (SCWO) is the process of complete destruction of toxic and hazardous organic wastes in a compact, totally enclosed system through oxidation in water brought to temperatures and pressures above its critical point: 374 °C

Laboratory-made polydimethylsiloxane (PDMS) membranes were subjected to plasma treatments with three different plasmas: an Ar, Ar-H2 and Ar-O2 plasma. Two parameters of the Ar-O2 treatment, the applied power and the treatment time, were evaluated. Th

The recently developed hydrolytic kinetic resolution (HKR) of epoxides catalysed by the Co-Jacobsen catalyst, is one of the most useful methods to obtain enantiomerically pure epoxides and/or diols. Several parameters can significantly influence the

Cement-based stabilisation processes are frequently used for immobilising wastes containing a variety of toxic compounds. In order to improve and extend cement-based stabilisation processes, research has been carried out to examine the role of carbon

In a high-temperature membrane reactor, one of the reaction products is selectively removed from the reaction mixture, thus preventing the mixture from reaching equilibrium. In a previous study [1] , a CVI-silica membrane was used for the direct dehy

High- T c superconducting thin films have been deposited in situ by means of a plasma assisted metal-organic chemical vapour deposition (PAMOCVD) process on LaAlO 3 . An EMCORE high-speed rotating disc reactor was used to deposit the films at a subst

YBa2Cu3O7−x tapes were made by a powder-in-binder technique, using polysulphone (PSF) as the organic polymer andN-methyl-2-pyrrolidone (NMP) as the solvent. The suspension is cast onto a glass substrate plate to form the tape (Doctor Blade method)

High-Tc superconducting filaments of the Y-Ba-Cu-O system were prepared using a low-cost suspension spinning method, where the solvent was removed by a phase inversion technique. The Y-Ba-Cu oxide precursor, containing polysulphone (PSF), was spun as
