In the men's Team event, Germany edged out Sweden in a six-match thriller.
Half of the last-16 encounters were completed at the ExCeL Arena tonight, with the remaining four to be played tomorrow morning.
In the pick of the action, Germany were pushed all the way by their Scandinavian opponents. The clash started with world number seven Timo Boll continuing his disappointing Games as he was beaten 3-1 by Jorgen Persson.
Boll was knocked out of the singles by the Romania's Adrian Crisan in the fourth round and did not fare any better versus veteran Persson.
But Dimitrij Ovtcharov, who claimed bronze in the individual format, got things back on track by overcoming Par Gerell.
Boll and Bastian Steger then combined to beat Gerell and Jens Lundqvist before the latter overcame Persson 3-0 to seal Germany's passage to the quarter-finals.
In the last eight, they will be joined by Austria, Hong Kong and Portugal, who eased to 3-0 successes against Egypt, Brazil and host nation Great Britain respectively.
