For example, I eat nothing, would be Je ne mangerien. Rien takes place of the 'pas' that you would usually use in a negative sentence.
'de rien' is a fixed expression that you use in reply to 'thank you' (as 'no problem' or 'you're welcome'). That form is never shortened. But rien ('nothing') is also used on its own: "qu'est ce que tu fais ? Rien" (what are you doing? Nothing.")
"Ne rien" in French means "nothing" or "not anything." It is often used in negations to indicate the absence of something.
Rien means 'nothing' or the negative form of 'anything' depending on the context. For example, -"Qu'as-tu fait" (What did you do?) -"Rien." (Nothing.) or -"Je n'ai rien fait." (I didn't do anything.) Note that rien is used in the place of 'pas' and is one of the many forms of the negative in French (e.g. ne...rien, ne...aucun, ne...personne).
