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.
Green Chemistry in the Lab
Mechanochemistry is a very effective method to carry out syntheses without solvents and by-products. The technical literature describes a great number of reactions where a conversion of 100% is achieved. A precondition for the establishment of mechanochemistry in the industrial sector is the availability of suitable laboratory mills. A decisive factor is that – similar to conventional preparative chemistry – ambient parameters such as pressure and temperature can be documented and monitored. The Planetary Ball Mills and Mixer Mills from Retsch fulfill these requirements.
La Fragmentación
Por lo general se asocia a la noción "fragmentación", el machacamiento, de sustancias sólidas mediante fuerza mecánica. Pero también la división de líquidos en gotas o de gases en bollas representa un proceso de fragmentación.
Consistent Milling on a Nano Scale
Planetary ball mills are helping scientists and engineers advance nanotechnology by providing a consistent way to produce nanoscale powders.
Sample Preparation of Solid Materials for the XRF-analysis
X-Ray fluorescence is one of the most versatile methods to determine elements in a sample. The material is exposed to x-rays that cause each element to emit its own unique fluorescent x-ray. The subsequent analysis of the results is based on comparisons to standard samples with given chemical composition.
Herstellung von Nanopartikel mit der Planeten-Kugelmühle
Die Herstellung von Nanopartikeln, deren Größe im Bereich von 1 Mikron und kleiner liegt, ist in vielen technischen Bereichen immer mehr auf dem Vormarsch, denn sie ermöglichen die gezielte Veränderung von Materialeigenschaften.
La nueva generación de molinas planetarios de bolas
Los más precisos resultados de trituración en el más breve tiempo se consiguen con los nuevos molinos planetarios de bolas, de Retsch. Con el PM100 y el PM200, Retsch presenta una nueva generación de molinos planetarios de bolas con uno o dos unidades de trituración, que establecen nuevos estándares de rendimiento en este segmento de la producción.
Zusammenspiel der Kräfte
Planeten-Kugelmühlen ermöglichen mechanisches Legieren dank ihrer hohen Zerkleinerungsenergie
Mechanisch legierte Werkstoffe haben schon längst ihren Einzug in die moderne Werkstofftechnik gehalten. Viele neue Werkstoffe und Werkstoffkomposite wurden in den letzten Jahren durch intensive Forschung entwickelt und werden bereits industriell hergestellt. Mechanisches Legieren ist ein gängiges Verfahren, um Werkstoffpaarungen oder Komposite zu synthetisieren, die auf konventionellem Wege nicht realisierbar wären, wie z. B. das Verbinden von Natur aus unmischbarer Legierungspartner. Das Werkzeug der Wahl dafür sind Planeten-Kugelmühlen.

Chemical activation of MgH2; a new route to superior hydrogen storage materials
We report the discovery of a new, chemical route for ‘activating’ the hydrogen store MgH2, that results in highly effective hydrogen uptake/release characteristics, comparable to those obtained from mechanically-milled material. Hydrogen is widely regarded as a promising alternative to carbonbased fuels; it can be produced from a variety of renewable resources and, when coupled with fuel cells, offers the prospect of near-zero emission of pollutants and greenhouse gases.1 However, the development of hydrogen as a major energy carrier will require solutions to many scientific and technological challenges. Foremost among these is the issue of hydrogen storage; the lightest of all the chemical elements has an excellent energy content per unit weight, but a low energy content per unit volume.
