    Product recovery solutions for nanoparticles industry

    An increasingly high number of industries, from the fine chemicals to the cosmetics industry, are investing on the design and production of nanoparticles, such as metal oxides, in specific reactors. There is a need to recover these very fine powders from the exhaust streams often at high temperature, pressure and moisture. The very fine particle size precludes the use of mechanical collectors by themselves. The main problem of using barrier filters is product hold-up and breakage of the nanoparticles. Client`s...

    Chemical oxygen demand (COD) analyzer for government and academic solutions

    PeCOD® is the only Chemical Oxygen Demand (COD) analysis technology to use the powerful UV-activated nanoparticle TiO2 (titanium dioxide) photocatalyst which is at the core of the system. The high electrochemical potential of the TiO2 gives it a substantial advantage over the modest chemical potential generated by the dichromate method. The UV light creates a photohole in the TiO2 sensor with a very high oxidizing power and organics in the cell are oxidized. PeCOD® is extremely accurate across a broader...

    Elemental Analysis for Woven & Nonwoven Fabrics by EDXRF / XRF

    Fabrics fall into two broad catagories: wovens and nonwovens. A woven is a cloth formed by weaving. Wovens only stretch in the bias directions, unless the threads are elastic. Nonwoven fabrics are broadly defined as sheet or web structures bonded together by entangling fiber or filaments created by mechanical, thermal or chemical processes.

    Zero valent iron nanoparticles for algae bloom removal

    Blue-green algae or cyanobacteria are gram-negative bacteria that obtain their energy through photosynthesis. They have a huge resistance to adverse conditions due to their simple construction. Typically, they occur in lakes, ponds and slow-moving streams but they can survive even in hostile environment due to their simple construction. Massive development of cyanobacteria is caused by the accumulation of nutrients in stagnant water (eutrophication). Algae Blooms can cause human allergic reactions manifesting by...

    Scientific instrumentation solutions for CMP slurries, content of large particles sector

    There are two papers published on subject of applicability of ultrasound for characterizing CMP slurries, see below. There are also 2 newsletters, # 1 and # 13 on the same subject. Acoustics provides accurate particle size that agrees well with independent data. It can monitor presence of 1% large particles on the background of small nano-particles. Electroacoustics yields very precise value of zeta potential. These measurements can be done with no dilution, which opens possibility for continuous on-line control...

    Particle Size Measurement

    Particle size is a geometric characteristic that is usually assigned to material objects with sizes ranging from nanometers to millimeters. There is a wide variety of real systems that contain particles within this size range. These systems are generally polydisperse, meaning that the particles in a particular sample vary in size. Therefore, in order to adequately characterize such systems, it is not sufficient to simply determine a single particle size. We must instead determine the system’s particle size...

    Erosion and dust control products for parking lots

    Envirotac line of polymers perform exceptionally well in constructing parking areas. Whether it be in-situ soils, road base, gravel, recycled asphalt, or decomposed granite Envirotac will lock the particles in place. It is great at controlling dust, preventing ruts and washboarding , and increasing the surface strength. Carbon black can be added to make the area look like asphalt and stripes can be painted over the surface.

    Zero valent iron nanoparticles for water treatment and purification

    All described properties of Fe(0) nanoparticles can be even used for decomposition of pollutants contained in the waste water, mainly for treatment of industrial sewage and hutch water. The usage of nanoiron can represent a significant qualitative step in the classical technologies of water treatment including drinking water. The extremely reactive iron nanoparticles thus offer a possibility to solve long-lasting problems with a high content of uranium and arsenic in a variety of localities in the Central Europe....

    Other possible application of iron nanoparticles

    Beside unexceptionable reduction properties, the nanoparticles of zero-valent iron also exhibit excellent catalytic, magnetic (strong ferromagnetic material) and mechanical properties due to which they could be, for example, used as: a catalyst in Fischer-Tropsch synthesis of hydrocarbons, in the production of carbon nanotubes, in petrochemistry, in the production of magnetic fluids, catalytic paint in combination of other noble metals, or as an admixture in powder metallurgy.
