  We classify bounded t-structures on the category of perfect complexes over a
commutative, Noetherian ring of finite Krull dimension, extending a result of
Alonso Tarrio, Jeremias Lopez and Saorin which covers the regular case. In
particular, we show that there are no bounded t-structures in the singular
case, verifying the affine version of a conjecture of Antieau, Gepner and
Heller, and also that there are no non-trivial t-structures at all in the
singular, irreducible case.
