In many industries where equipment comes in contact with water, including those that rely on water treatment membranes, equipment fouling is a huge problem. Biofilm fouling occurs when living organisms — including bacteria, algae, and even mollusks — become attached to boat hulls, harbor structures, and other equipment. The resulting damage can be costly. Coatings and other chemical ...
As 2014 comes to a close and we prepare to celebrate Ensia’s second anniversary this coming February, I wanted to take a moment to reflect on the journey we’ve been on over these past couple of years. In my role as Ensia’s director, I often meet with potential partners, supporters, thought leaders and others. More often than not, one of the first questions I’m ...
Short‐term (60 min) Eu biouptake fluxes by the freshwater green alga, Chlamydomonas reinhardtii, were investigated in the presence and absence of ligands (e.g. malic acid and citric acid) and a second rare earth metal (Sm). Data were interpreted in the context of the biotic ligand model (BLM), which uses experimentally determined stability constants in order to take into account the ...
Earbuds, touch screens, CFLs with a warm glow, rechargeable batteries and power windows: Most of us take these things for granted. When we do, we also take for granted a group of elements called rare earth metals, whose special electronic and magnetic properties make them a key component of many 21st century technologies. These 17 elements are actually plentiful enough — you probably have ...
In a report published on November 4th, the European Joint Research Centre (JRC) has warned of the "risk of shortage" in 2020-2030 of eight strategic metals used in low carbon energy technologies identified in the European SET Plan adopted in 2008. This report continues the work done in a previous study of the JRC from 2011. It is also based on the scenarios presented in 2011 in the roadmap of ...
While using NdFeB (i.e. neodymium, iron and boron) sintered magnets in motors' production, the most important requirement of magnet is that the thermal demagnetization should never happen. The so-called thermal demagnetization is a kind of irreversible demagnetization; only by re-magnetizing can the initial flux be insured. When a motor is working, the environment ...
It's mid-July 2011, the construction industry is still trying to find a little traction and the lighting industry is bracing itself for historic price increases of epic proportions from fluorescent lamp manufacturers. In the 'post recession' this seems to be the new norm; not only do we have to bail water but do it during a hail storm as ...
