A proton induced x-ray emission (PIXE) spectrometer is used to determine the elemental composition (10Z82) of complex samples, such as minerals, paints, foodstuffs, archeological objects, and others.

Chadwick's own research focused on radioactivity. In 1919 Rutherford had discovered the proton, a positively charged particle within the atom's nucleus. But they and other researchers were finding ...

The emission of beta radiation provides evidence that neutrons and protons are made up of quarks. Beta (\(\beta^-\)) decay is the release of an electron by the change of a neutron to a proton.

On Proton’s first electric vehicle (EV), the e.MAS 7, Anwar said it embodies Malaysia’s commitment to achieving net zero emissions. He noted that Proton had aggressively promoted the vehicle ...
