Chemicals that keep drinking water flowing may also cause fouling

Many cities drinking water systems add softening agents to keep plumbing free of pipe-clogging mineral build-up. According to new research from the University of Illinois, these additives may amplify the risk of pathogen release into drinking water by weakening the grip that bacteria – like those responsible for Legionnaires’ disease – have on pipe interiors. Biofilms, which are similar to the films that grow on the glass of fish tanks, are present in almost all plumbing systems and anchor themselves to mineral scale build-ups in pipes. They are teeming with harmless microbial life and incidents of waterborne illness are rare. Read More

Many foods produced on an industrial scale include raw ingredients mixed together in enormous stainless-steel machines that can be difficult to clean. With repeated use, equipment surfaces get minute scratches and grooves, providing bacteria and biofilms the perfect place to hide. While surface scratches may appear small to the naked eye, they are like a canyon to bacteria, which are only a few micrometers in size. Surface-trapped food residue and bacteria then increase the risk of contamination from microorganisms such as SalmonellaListeriaandE. coliRead More

 

For more than a decade in the middle of the 20th century, chemists debated exactly what carbocations — molecules with a positively charged carbon atom — looked like. What is known as the “classical view,” which was taught at the beginning of that century, stated that the carbon in these molecules held the charge; the “non-classical view” held that the charge could also be shared by other nearby atoms. Both theory and experiment eventually proved that non-classical carbocations existed, and the debate faded away. Even if these structures exist, most chemists believed, they had no practical relevance. Read More

Reverse Osmosis: Water Treatment Process


Reverse Osmosis: Water Treatment Process

Reverse Osmosis (RO) is a water purification methodology that removes ions, molecules and other larger particles from drinking water using a semipermeable membrane. The process of removing salt from seawater or desalination is done by reverse osmosis. History of Reverse osmosis: The process of Reverse Osmosis by using semipermeable membrane was observed first in 1748 by a French clergyman and physicist Jean Antoine Nollet. University of California at Los Angeles was the first to investigate in 1950, desalination of seawater using semipermeable membranes. Read More

Trinseo is celebrating the 10th anniversary of its Lomax technology at its plant in Dalton, Georgia. The plant runs largely on alternative energy, significantly reduces carbon dioxide (CO2) and greenhouse gas emissions, thanks to manufacturing process of Lomax Technology. Lomax Technology uses methane gas collected from a nearby landfill as the primary energy source to manufacture Trinseo’s latex binders. The methane is piped to a landfill gas energy recovery facility and then to the Trinseo plant, where the energy is used to power the plant’s boiler. This virtually eliminates the need for natural gas. Read More

Material made from crab shells, trees could replace plastic packaging


From liquid laundry detergent packaged in cardboard to compostable plastic cups, consumer products these days are increasingly promoting their sustainable and renewable origins. Now researchers at Georgia Institute of Technology have created a material derived from crab shells and tree fibres that has the potential to replace the flexible plastic packaging used to keep food fresh. The new material, which is described in the journal ACS Sustainable Chemistry and Engineering, is made by spraying multiple layers of chitin from crab shells and cellulose from trees to form a flexible film similar to plastic packaging film.

Fish are losing their sense of smell because of increasingly acidic oceans caused by rising levels of carbon dioxide (CO2) in the atmosphere, new research shows. When carbon dioxide is absorbed by seawater carbonic acid is formed, making the water more acidic. Since the Industrial Revolution, oceanic CO2 has risen by 43 percent and is predicted to be two and a half times current levels by the end of this century. Fish use their sense of smell (olfaction) to find food, safe habitats, avoid predators, recognize each other and find suitable spawning grounds. A reduction in their ability to smell therefore can compromise these essential functions for their survival. Read More

Living solar cells produce energy, even in bad weather


Living solar cells produce energy, even in bad weather

When it comes to generating energy from sunlight, unusual solutions have been shown to make the process more efficient. Now, a team of researchers from the University of British Columbia (UBC) has demonstrated how solar cells made of living organisms can generate energy even with limited sunlight. Known as “biogenic” solar cells, these cells could offer an alternative to synthetic cells currently used in conventional solar panels, providing an energy source despite bad weather. A paper detailing the research was published in the journal Small. In the past, researchers have developed biogenic solar cells by extracting natural dyes that bacteria use to generate energy in photosynthesis. Read More

Lava flows to affect geothermal power generation in Hawaii


Lava flows to affect geothermal power generation in Hawaii

A report from the Energy Information Administration (EIA) states that the Lava flows from the Kilauea volcano on the island of Hawaii led to the shutdown of the Puna Geothermal Venture (PGV) power plant on May 3, 2018. The 38-megawatt (MW) facility is the only geothermal plant on the island, and it produced about 29 percent of the island’s electricity generation in 2017. The plant voluntarily ceased operations ahead of the approaching lava flow. Continuing eruptions in lower Puna, the south-eastern corner of the island, have damaged transmission lines and equipment, and local residences are experiencing extended power outages. Read More

An Ultimate Guide on Diamond

History and Etymology: In 4th century BC, diamonds were first discovered and mined in India. Diamondin India had been known for at least 3000 years but 6000 years most likely. Diamonds popularity got increased since 19th century after its increase in supply, improved polishing and cutting techniques. In 327 BC, Alexander brought first diamond to Europe from India. French scientist Antoine Lavoisier in 1772 showed that the only product of the combustion of Diamond is Carbon dioxides, hence proving that diamond compose of only carbon. Later on chemist Smithson Tennant in 1797, repeated and expanded the experiment and demonstrated that diamond and graphite releases same amount of gas. Read More
