Rauf wrote that Haji arranged for a trainer called Marwan Suri to provide bomb-making training using hexamine peroxide detonators and hydrogen peroxide.

It is contained within the case of the rocket, into which is pumped a liquid oxidiser called high-test peroxide (HTP), a concentrated form of hydrogen peroxide which is relatively safe to handle.
Hydrogen peroxide-based bombs are something of a signature of al Qaeda plots in recent years.

Hydrogen peroxide is better for the environment because it breaks down to just water and oxygen.
Headwaters is also working on hydrogen peroxide plants and a coal-to-liquids technology in Asia.
Siddique Khan and Tanweer test-detonated a 300-gram hydrogen peroxide mixture in the tribal areas.

This followed a deep-cleaning process known as "fogging", which uses hydrogen peroxide vapour.
Bees also secrete an enzyme that adds a small amount of hydrogen peroxide.
Shortly before the attack, Siddique Khan began to boil down hydrogen peroxide to turn into explosives in an apartment in Leeds.

As bees make honey they secrete glucoseoxidase, an enzyme that releases the bleach hydrogen peroxide when it comes into contact with wound liquids.
During the summer of 2009 Zazi, a resident of Denver, obtained a large amount of hydrogen peroxide from a beauty store in Aurora, Colorado.

In the latest case, examples of wrongdoing included suspects using a hydrogen peroxide solution to process chicken claws or injecting water into meat to increase its weight.
For example, attempts to buy large amounts of fertilizer or other ingredients -- such as hydrogen peroxide -- used in bomb-making are often relayed to law enforcement agencies.
Rauf described how the duo then began purchasing bomb components, including hydrogen peroxide in gardening stores, hexamine in camping stove fuel and citric acid, which was easily available.

Researchers were unable to explain what caused the results, although they did note the treatment led to the formation of hydrogen peroxide, a chemical known to be toxic to cells.
Sunday flight east, he called his girlfriend, who recommended he give Sierra some low-concentration hydrogen peroxide solution, which many recognize as a safe way to get a dog to vomit.
At key points, components will go through further careful cleaning with ethanol and a thorough sterilisation with hydrogen peroxide vapour which, to add to the challenges, has to kept above 15C.
Al Qaeda terrorists have increasingly turned to using hydrogen peroxide-based bombs because it has become very difficult for militants based in the United States and other Western countries to buy conventional explosives.

And it's believed that the high chemical reactivity of the surface is due to the deposition of chemically active gases from the atmosphere onto the surface, gases like hydrogen peroxide and ozone.
Unlike the batteries in traditional arms, which die quickly, a small canister of hydrogen peroxide concealed in the arm can last up to 18 hours, and provides about the same power and functionality of a human arm.

In a 2009 plot to bomb the New York City subway system, suspect Najibullah Zazi was able to purchase significant quantities of hydrogen peroxide, which he hoped to distill to a higher concentration that would make an effective bomb.
But the industry has a large offsetting advantage: It is still rebounding from a shakeout a few years ago after environmentalists forced paper companies to stop using chlorine as a bleaching agent (many shifted to supposedly greener hydrogen peroxide).
He said in addition to hand washing, other useful strategies would be screening patients for MRSA on admission, regular use of hydrogen peroxide vapour generators to kill bugs in the hospital environment and educating patients and visitors on ways they can reduce risk.
BBC: Hand washing is the most effective way of battling MRSA
Revolutionizing Prosthetics 2009 program, relies on a modified miniature version of the same rocket motors the space shuttle uses to reposition itself in space: hydrogen peroxide is burned in the presence of a catalyst to produce pure steam, which is then used to move the arm.
