• New lithium collection method could boost global supply

  With continual technological advancements in mobile devices and electric cars, the global demand for lithium has quickly outpaced the rate at which it can be mined or recycled, but a University of Texas at Austin professor and his research team may have a solution. Benny Freeman, professor in the Mc more

• Fixing by Filtration

  Many heavy metals are toxic to the environment or to humans. Legal limits for these pollutants in drinking water and run-off are thus correspondingly low. Rapid on-the-spot analysis and routine water quality tests demand a rapid, cost-effective method that doesn't require complex instruments. Test s more

• 3M to Acquire CUNO

  3M and CUNO Inc. announced that they have entered into a definitive agreement for 3M's acquisition of CUNO in an all cash merger for $72 dollars per share, valuing the transaction at approximately $1.35 billion including the assumption of $60 million of existing net debt. CUNO is a leader in the des more

• Application-specific Membrane Prefilters for Highly Efficient Processes in Biopharmaceutical Production
  

  New medicines and diagnostics on the one hand and rising cost pressure as a result, for example, of the launch of generics and biosimilars on the other mean that new, highly efficient methods are required in biopharmaceutical production. In order to more

• Filter Integrity Testing
  

  The integrity testing of sterile filters constitutes a critical and mandatory regulatory step in biopharmaceutical production processes. However, performing such filter integrity tests costs time. Indeed, it can take a good 20 to 30 minutes to perfor more

• A Flow‐through Column Electrolytic Cell for Supercritical Fluid Chromatography#

  A novel flow‐through column electrolytic cell was proposed as a detector to obtain current signals for supercritical fluid chromatography. The electrochemical cell consisted of two electrodes and its holder, and a working and a counter electrode were fabricated from 192 carbon strings, which were more

• Heads you win, tails you lose: filtration processing for the microscopical examination of sperm heads

  Summary The sperm head plays a key role in many fertilisation events and determining the precise location of molecules within the head region is important in mechanistically dissecting the fertilisation process. Such molecules may be present in low copy number and many sperm head profiles must b more

• Does adsorption of dissolved organic carbon and thorium onto membrane filters affect the carbon to thorium ratios, a primary parameter in estimating export carbon flux?

  Publication date: 20 August 2016 Source:Marine Chemistry, Volume 184 Author(s): Kuanbo Zhou, Kanchan Maiti, Minhan Dai, Shuh-Ji Kao, Ken Buesseler The particulate organic carbon (POC) to 234Th ratio, or POC/234Th, is crucial to constrain the 234Th-derived downward export flux. Marine more
