                      and wide-angle polarization analysis, DNS is optimized as a
                      high intensity medium resolution cold-neutron polarized
                      instrument at MLZ. Major instrument upgrades, including the
                      installations of a new Fe/Si supermirror based focusing
                      polarizing bender [1], a 300 Hz disc chopper system, and a
                      neutron velocity selector for high-order rejection, have
                      been accomplished recently. In addition to the resulted
                      significant performance gain, this has also allowed to
                      combine polarized neutrons with time-of-flight spectroscopy
                      for the studies of emergent quantum materials, such as
                      quantum spin liquid, quantum spin ice, Kitaev materials and
                      correlated topological materials etc. In this presentation,
                      an overview about the recent major instrument upgrades and
                      some selected examples [2-5] on the studies of quantum
