Improved Production of MoS2 Nanoparticles

07.02.2007
Ground crystalline molybdenum sulfide (MoS2) has reliably proven itself as a universal and inert solid lubricant. Its lubricity could lately be outperformed by nano-MoS2 which fills smaller surface roughnesses and exerts lower inter-particle shear resistance. Through a crucial modification of its manufactoring process the synthesis of nano-MoS2 in a two-step reaction starting from ammonium heptamolybdate now succeeded. The overall process results in a mixture of multi-walled, hollow inorganic fullerene (IF) and nanotube (NT) particles of which softer elasticities are expected compared to previously known materials containing residual oxidic cores.

Im Focus: Explosion on Jupiter-sized star 10 times more powerful than ever seen on our sun

A stellar flare 10 times more powerful than anything seen on our sun has burst from an ultracool star almost the same size as Jupiter

  • Coolest and smallest star to produce a superflare found
  • Star is a tenth of the radius of our Sun
  • Researchers led by University of Warwick could only see...

Im Focus: Quantum simulation more stable than expected

A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers which are otherwise challenging for conventional computers. This brings such digital quantum simulation within reach on quantum devices available today.

Quantum computers promise to solve certain computational problems exponentially faster than any classical machine. “A particularly promising application is the...
