• Keeping fruit, vegetables and cut flowers fresh longer

  New technology offers the promise of reducing billions of dollars of losses that occur each year from the silent, invisible killer of fruits, vegetables and cut flowers — a gas whose effects are familiar to everyone who has seen bananas and other fruit ripen too quickly and rot. That's the conclusio more

• X-ray nanoscopy of cobalt Fischer–Tropsch catalysts at work

  Cobalt Fischer–Tropsch catalysts have been investigated in both 2-D and 3-D, by scientists in the Netherlands and the US, using in situ hard X-ray transmission X-ray microscopy (TXM). The Fischer–Tropsch process is an important step in the production of liquid fuels from natural gas, biomass or coal more

• Could zeolites make cigarettes safer to smoke?

  A self-protecting zeolite catalyst that degrades the carcinogens in cigarette smoke has been reported by scientists. The zeolite – which is prepared in a one-step hydrothermal crystallisation without any post treatment or shape direction – selectively breaks down tobacco specific nitrosamines (TSNA) more

• Measuring particle size using modern laser diffraction techniques
  

  Many different techniques have been devised for determining particle size distribution, but for a wide range of industries laser diffraction has become the preferred choice. Laser diffraction, alternatively referred to as Low Angle Laser Light Scattering (LALLS), can be used for the non-destructive analysis of wet or dry samples, with particles in the size range 0.02 to 2000 micron and has inherent advantages which make it preferable to other options for many different materials. more

• Flexibility and variety thanks to a PTFE lining: Berghof highpreactor high pressure reactors
  

  With over 25 years’ experience in the construction of pressure vessels behind it, Berghof is offering an innovative device concept for many types of applications in research and development laboratories. Chemical reactions, which take place under temperature and pressure requirements ranging up to 260°C/200bars, are the applications for which Berghof highpreactor are designed more

• Polyolefins: Determination of Molecular Weight and Branching Structure by GPC/SEC

  Polyethylene and Polypropylene are so-called Polyolefins. They are produced in large amounts every year. Depending on the process and catalyst used linear or branched polymers can be produced. In case of e. g. Polyethylene there are at least three polymer types: HDPE (High Density Polytheylene), LDPE (Low Density Polyethylene) and LLDPE (Linear Low Density Polytehylene). HDPE and LLDPE are made of linear or only slightly branched macromolecules with a high level of crystallinity. They form a dense structure in the final product. LDPE is made of highly branched molecules that form a final structure with low density due to a low degree of crystallinity. more

• Synthesis of some fluorescent benzimidazole derivatives using cobalt(II) hydroxide as high efficient catalyst - Spectral, physico-chemical studies and ESIPT process

  Some fluorescent benzimidazole derivatives have been designed and synthesized using cobalt(II) hydroxide as high efficient catalyst. Synthesized compounds have been characterized by 1H, 13C-NMR and mass spectral analysis. The solvent effect on the absorption and fluorescence bands has been analyzed more

• Magnetite-supported sulfonic acid: a retrievable nanocatalyst for Ritter reaction and multicomponent reactions

  Magnetite-sulfonic acid (NanocatFe-OSO3H), prepared by wet-impregnation method, serves as a magnetically retrievable sustainable catalyst for the Ritter reaction, among others, and can be used in several reaction cycles without any loss of activity. more

• Highly efficient synthesis of cyclic ureas from CO2 and diamines by a pure CeO2 catalyst using a 2-propanol solvent

  Pure cerium oxide (CeO2) acts as an effective and reusable heterogeneous catalyst for direct synthesis of cyclic ureas from CO2 and diamines even at a low CO2 pressure of 0.3 MPa. 2-Propanol is the most preferable solvent to provide good selectivity. The system composed of a CeO2 catalyst and a 2-pr more
