Silicio per l’energia solare
I semiconduttori sono utilizzati per una grande varietà di applicazioni elettroniche, come circuiti integrati (microprocessori, microcontrollori, ecc.) rilevatori ottici e sorgenti di radiazioni (es. emettitori di luce), ma in modo particolare per i fotovoltaici, tramite i quali l’energia solare viene trasformata in potenza elettrica. Per la maggior parte delle applicazioni, il silicio è il materiale semiconduttore scelto.

Preparation of Soil, Sewage Sludge and Sediment Samples in a Wastewater Treatment Laboratory
The preparation of a mixture of organic and inorganic samples holds some difficulties: whereas sand, clay and stones can usually be ground to homogeneous samples with suitable laboratory mills, the high energy input can cause samples with organic components such as fat or starch to cake. Carsten Bunn, a laboratory technician at the waste water treatment laboratory BRW, has to deal with this problem every day. He treats samples which are taken from the sand traps of the wastewater treatment plants and consist of exactly that mixture. The sediments of household and industry waste water not only contain sand, clay or leaves but anything that people nowadays dispose of through the sewer system: cellulose, hair and especially food residues.

Cement - representative sample preparation is important
To produce high-quality cement, the mineralogical and chemical composition of raw materials as well as intermediate and finished products has to be determined. At each stage of the production, samples have to be taken, processed and analysed to ensure quality control without gaps. Retsch offers a range of instruments that are used for sample preparation during the complete production process, from the quarrying of the raw materials to the final product. The typical sample preparation process involves preliminary size reduction, sample division and fine size reduction before the sample can be submitted to further analyses....

Size reduction within the context of sample preparation
In general “size reduction” is taken to mean the disintegration of solid substances by mechanical forces without altering their state.

The preparation of samples of solid substances for spectroscopic analysis
X-ray fluorescence spectrometry is one of the most versatile multi-element methods of chemical analysis. The technique is based on excitation of fluorescent radiation from a sample by bombarding it with high energy X-ray quanta and subsequent study of the characteristic X-ray radiation emitted by its elements.
