This article has recently been published and it provides a general overview of airborne dust particles, their hazards and approaches to measure, quality, and quantify airborne dust particles. The article also includes the recent development at Delft Solids Solutions related to the so-called “Continuous Drop” methodology for respirable and inhalable …
Delft Solids Solutions organizes an open day in its new building in Wateringen. On the 15th of May you can drop by at the Molenweer 2 B in Wateringen from 13:30 onwards. There will be a poster seminar in which we explain our activities in a transparent way and you …
In its February 2014 edition, number 1, the Dutch magazine “BULK Solids Processing Handling” features an extensive description of Delft Solids Solutions’ new facilities and ongoing case studies. The image below links you to the on-line edition of the respective article (in Dutch). Enjoy reading!
Delft Solids Solutions has recently moved to a new location in Wateringen. Beside new offices and a new laboratory space, divided over three different labs with a total area of 250 m2, we now also possess a so-called Field Testing Area. This latter facility has an area of 200 m2 and …
With great pleasure we can inform you that since February 17th, 2013, the laboratory of Delft Solids Solutions has been approved as validated supplier of nano particle characterization by the “Joint Research Centre” of the European Community. Especially in view of the more stringent regulations on the registration of nanomaterials and the possible presence …
Various methods for assessment of dustiness potential Delft Solids Solutions now offers a variety of instruments and methods to investigate the dustiness potential of (powdered) solids. The Heubach method quantifies the total suspended dust content. This method is practised in accordance with the German DIN 55992 standard and the total dust is typically expressed in mg/kg (ppm). …
On February 16, 2012, Dr. Johan Groen will give a lecture at the Shell Hysomer symposium in Amsterdam. This talk will cover the latest developments and technologies of mesoporous zeolites and their role in catalysis. These hierarchically structured materials are very effective in reducing transport problems in the zeolite crystals …
A close collaboration of 4 years of Delft Solids Solutions wth leading scientists in an IUPAC (International Union of Pure and Applied Chemistry) framework has led to an in-depth article on the characterizaton of macroporous solids. In this paper, various techniques that are potential alternatives for mercury intrusion porosimetry are being reviewed. The paper has just been published in Pure …
Close cooperation with two leading research institutes in Europe has led to two new research contributions in scientific journals. The first paper describes the full compositional flexibility of the desilication post-treatment leading to combined micro- and mesoporous zeolites over the full range of Si/Al ratios. This confirms the universality of …
Considerable efforts are often devoted to the mixing of several different species of powders (of various sizes, shapes and densities) in order to have a homogeneous mixture of the intermediate or final product. Nevertheless, a well-mixed system may segregate during handling, e.g. when discharging into a bin or big-bag, transportation in a truck or …
