After years in development, Clean Water Systems & Stores Inc has introduced a new water purification system that removes a wide variety of contaminants from contaminated well and surface waters using a combination of hydrogen peroxide, ozone and UF technologies. Santa Cruz, CA (PRWEB) December 14, 2012 Clean Water Systems has introduced its new line of easy-to-install peroxide-ozone water treatment systems with UF to meet the needs of homeowners and small communities on contaminated...

The National Institute of Standards and Technology (NIST) has released a new standard reference material (SRM) to aid in the detection of two explosive compounds that are known to be used by terrorists. Researchers designed the new test samples to simulate the size and behavior of residues that remain after handling the explosives PETN (pentaerythritol tetranitrate) and TATP (triacetone triperoxide). Instrument developers, academic researchers and government labs can use the SRM to test,...

Molecular 'Culprit' Linked To Rise Of Planetary Oxygen
2012-01-11 04:34:18

A turning point in the history of life occurred 2 to 3 billion years ago with the unprecedented appearance and dramatic rise of molecular oxygen. Now researchers report they have identified an enzyme that was the first — or among the first — to generate molecular oxygen on Earth. The new findings, reported in the journal Structure, build on more than a dozen previous studies that aim to track the molecular evolution of life by looking for evidence of that history in present-day...

Lynn Yarris, Berkeley Lab A unique new probe based on luciferase, the enzyme that gives fireflies their glow, enables researchers to monitor  hydrogen peroxide levels in mice and thereby track the progression of infectious diseases or cancerous tumors without harming the animals or even having to shave their fur. Developed by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley, this new bioluminescent probe has already...

University of Illinois chemists have developed a simple sensor to detect an explosive used in shoe bombs. It could lead to inexpensive, easy-to-use devices for luggage and passenger screening at airports and elsewhere. Triacetone triperoxide (TATP) is a high-powered explosive that in recent years has been used in several bombing attempts. TATP is easy to prepare from readily available components and has been difficult to detect. It defies most standard methods of chemical sensing: It doesn't...

A Dutch-German medical research team led by Harald Schmidt from Maastricht University, Netherlands, and Christoph Kleinschnitz, University of Wrzburg, Germany, has discovered that an enzyme is responsible for the death of nerve cells after a stroke. The enzyme NOX4 produces hydrogen peroxide, a caustic molecule also used in bleaching agents. Inhibition of NOX4 by an experimental new drug in mice with stroke dramatically reduces brain damage and preserves brain functions, even when given hours...

If a circadian rhythm is like an orchestra - the united expression of the rhythms of millions of cells - a common chemical may serve as the conductor, or at least as the baton. The chemical is hydrogen peroxide (H2O2), the active ingredient in color safe bleach. Produced in all animal cells, hydrogen peroxide may act as a signal for the active and resting phases of living things, new research by USC biologists suggests. A study published in the journal PLoS ONE shows that hydrogen peroxide...

Weizmann Institute Scientists Develop a Unique Approach for Splitting Water into Hydrogen and Oxygen The design of efficient systems for splitting water into hydrogen and oxygen, driven by sunlight is among the most important challenges facing science today, underpinning the long term potential of hydrogen as a clean, sustainable fuel. But man-made systems that exist today are very inefficient and often require additional use of sacrificial chemical agents. In this context, it is important to...

By Loraine, Gregory A ABSTRACT: In this paper, components of an industrial wastewater that cause operational problems during biological treatment were oxidized by UV light and hydrogen peroxide (UV/H^sub 2^O^sub 2^). Preoxidation of wastewater was shown to remove polyvinylpyrrolidone (PVP) and ethoxylate surfactant and increase overall biodegradability. Several UV intensities and hydrogen peroxide concentrations were tested to find optimal conditions for the complete depolymerization of PVP...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
