In this method, the particles are treated with ammonia gas to get the nitrogen into the crystal structure. Alternatively, iron oxide can be mixed with ammonium nitrate in a planetary ball mill ...

Chemists from the CNRS have studied the properties and efficacy of iron oxide nanoparticles as potential agents for magnetic hyperthermia. This promising cancer treatment technique involves locally ...

Inside such a structure, reflections from the periodic interfaces can cause constructive and destructive interference. A common use of this effect is for anti-reflection coatings. However ...

Pure iron is unobtainable by smelting, but small amounts of impurities can make iron many times stronger than it exists in its pure form. Iron oxide compounds, when mixed with aluminum powder, are ...

This oxygen combined with dissolved iron in the sea to form insoluble iron oxide, which sank to the sea floor. As it settled, sheets of red iron oxide were laid down between layers of silica-rich silt ...

While this is a project that resulted in a completed base for a CNC machine, this is also an experiment to determine the best formula for ... dye (in the form of iron oxide and liquid epoxy ...

There’s another way of making a structure. A shell structure is just made of a thin, curved outer layer and it’s hollow inside. Like this, or this, or this, or this. A shell structure doesn ...

Scientists have developed a new material capable of capturing the harmful chemical benzene from the polluted air, offering a potential solution for tackling a major health and environmental risk.

The government is planning to make possession of nitrous oxide - also known as laughing gas - a criminal offence in England and Wales. Known as NOS, its use as a recreational drug soared during ...

The government made the possession of nitrous oxide, or laughing gas, a criminal offence in England and Wales, as part of plans to tackle anti-social behaviour. Its use soared during the pandemic ...
