In an effort to investigate the reactions taking place in a biological cell, scientists tried to replicate them in an artificial cell. Such experiments have so far worked with very simple reactions, but the team managed to establish a complex biochemical reaction in tiny droplets only a few micrometres in size.
Researchers have discovered that by compressing sodium chloride (rock salt) under certain high-pressure conditions, they can trigger a process which was found to form new compounds - despite chemistry textbooks saying this is impossible.
With a 3D printer, open-source software and free digital designs, cash-strapped scientists can now fabricate their own lab equipment at a fraction of the cost.
The Patch Test Kit (or Portable Contamination Analysis Kit) is a tool for identifying and monitoring the types and levels of particulate contamination in all fluid power systems, including those offshore where water-based fluids are utilised.
An African medicinal plant - Nauclea latifolia (also known as the pin cushion tree) - has been found to produce large quantities of molecules with analgesic properties. Even more surprising, analysis shows that the molecule is identical to the heretofor wholly synthetic painkiller Tramadol.
The WaterTest Kit is used for the quantitative determination of water content in % of mineral and lubrication oils. The simple addition of two reagents to the contaminated oil causes an increase of pressure in the measuring cell. This pressure increase is read off via the digital display as water content in % or ppm.
Professors Stephen Trumble and Sascha Usenko, of Baylor University, have developed a new method to determine the lifetime chemical profiles of blue whales. As revealed in the journal Proceedings of the National Academy of Sciences, the scientists found the answer in the whales’ earwax plugs.
University of Waikato Biological Sciences Professor Vic Arcus and his research group have been awarded $850,000 for a two-year project to develop a new method for designing ‘next-generation enzymes’ for commercial use.
Until now, only 36 basic types of chemical reactions have been identified. But a 37th type has just been added to the list.
Chemists have discovered that an ‘impossible’ reaction at cold temperatures actually occurs with vigour, which could change our understanding of how alcohols are formed and destroyed in space.
The Hanby TPH Field Test Kit system is a field-portable method providing rapid analyses down to ppb for aromatic compounds, including gasoline, diesel, PCBs and many others. The procedure extracts the aromatic compounds from the sample and provides immediate colorimetric identification of the concentration and type of contaminants present.
Sophisticated instruments small enough to fit in a shirt pocket will one day scavenge power from sunlight, body heat or other sources enabling analysis in the field rather than bringing samples and data back to the lab.
New technology is paving the way for low-cost electronic devices that work in direct contact with living tissue inside the body.
PAC has released its latest jet fuel thermal oxidation analyser, the Alcor JFTOT 230 Mark IV (JFTOT IV). It adds enhanced safety features and simplified operational capabilities to its previous versions, increasing operator productivity, in a smaller, streamlined package.
Microwave radiation could provide a faster, greener way to manufacture drugs.
