Processing Architecture

The current paper presents the design of a glass panels recycling flow and the method used for establishing the optimal processing installation architecture. In the solution provided in the current research, a novel approach centred on applying digital twinning in the design of the requested processing architecture is presented. It involves designing the virtual prototype of the diffused processing architecture and modelling the glass waste flow as a hybrid material flow. Dedicated analysis and simulation software is then used for establishing installation architecture and the specific parameters for each processing and transport capacity. The assessment of different processing scenarios by virtual modelling and simulations can also be used for exploring options to increase productivity and profit for other different recycling architectures. The main practical value of the study consists of creating the means to improve the waste recycling of automotive windshields, float glass or construction glass panels with metallic meshes, all representing categories of waste insufficiently recycled in Romania. The simulation results of the study were validated by tests made on the glass panel recycling installation. Also, a recovery glass rate of minimum 85% of the amount of waste loaded into the recycling system was achieved, obtaining a waste recycling quantity three times higher than initially anticipated.

Major Increase

An enhanced microdialysis method for neuropeptides is described and some preliminary results of this novel approach are presented. The enhancement is achieved by adding a vehicle (solid support) to the perfusion fluid in order to increase the diffusion coefficient across the membrane and efficiently transport the analytes towards the detector. The microdialysis samples are desalted and then analyzed on an electrospray ionization orthogonal time-of-flight mass spectrometer. The preliminary results show major increase in signal when comparing this new approach of microdialysis with ordinary microdialysis.

Zinc Oxide Powder

AbstractA novel approach to the determination of crystallite size and lattice strain by means of Total Pattern Analysis is described. Parameters to define the position, magnitude, breadth and shape of individual peaks are obtained by an adaptation of the pattern fitting program of Sonneveld and Visser (J. Appl. Cryst. 8, 1–7, 1975). A rapid assessment of the nature of the specimen broadening is given by a Williamson-Hall Plot. This leads to a more detailed study of line breadths by, for example, Voigt analysis applied to several orders of reflections or to single lines. Preliminary results are given for the application of this procedure to ‘size only’ and ‘size-strain’ samples of ZnO.
