Snag about English becoming advanced in scientific applications (6)

I believe the answer is:

hitech

I'm a little stuck... Click here to teach me more about this clue!

'advanced in scientific applications' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'snag about english' is the wordplay.
'snag' becomes 'hitch' (synonyms).
'about' means one lot of letters goes inside another.
'english' becomes 'E' (abbreviation as in OED).
'hitch' enclosing 'e' is 'HITECH'.

'becoming' acts as a link.

Can you help me to learn more?

(Another definition for hitech that I've seen is " Using sophisticated electronics".)

I've seen this clue in The Times.
