Over the past century‚ as a side effect of food production‚ humans have been releasing huge amounts of nutrients‚ specifically nitrogen and phosphorus into water resources like lakes‚ rivers and even oceanic coasts. This has caused enormous growth in algae populations‚ literally choking the life out of aquatic ecosystems and polluting water for humans as well. These “Harmful Algal Blooms” (HAB’s) or green tides as some call them can produce toxins that can hurt animals and humans alike turn water

The industrial separation process that I have decided to do is gold separation. Gold separation can be done in a number of ways but there is not always one way to do it‚ but the combination of a couple of these processes to extract pure gold. Gold is obtained form the lithosphere. It is separated from the ore found in the lithosphere. Gold’s symbol is Au. Its atomic number is 79 and has an atomic mass of 196.96655 amu. Its melting point is 1064.43°C‚ while its boiling point is 2807.0 °C. It is

One of these new methods is the custommade lining of all specimen housings with Plastazote®‚ a closed cell cross-linked polyethylene foam‚ protecting these extremely fragile specimens from being destroyed by being loose in card or plastic boxes. The standardization of box sizes and the need to create thousands of pads for them involved a painstaking task that even the most willing

Europe Biodegradable Plastics Market Forecast and Opportunities‚ 2019 Released On 23rd July 2014 Biodegradable plastics are the type of bioplastics that can be decomposed by micro-organisms. They can be derived either from renewable polymers such as starch‚ starch blends and polylactic acid (PLA)‚ or from petroleum feedstock such as polycaprolactone (PCL) and polybutyrate. Based on the source material‚ biodegradable plastics are classified as biobased and fossil based biodegradable plastics
