Researching on-chip erbium-doped lithium niobate microcavity lasers

As a complement to silicon-based photonic chips, lithium niobate thin film (LNOI) has become a research hotspot in the field of optoelectronic integration due to its outstanding nonlinear, electro-optic, acousto-optic, piezoelectric ...

Scientists demonstrate how to improve steel properties

Scientists from Tomsk Polytechnic University have updated the alloying process, i.e. improving the properties of metal with impurities, which not only enhances the wear resistance of materials but also provides new qualities ...

Atomic nitrogen route to new 2-D semiconductors

A simple and non-destructive fabrication technique could aid the manufacture of more energy efficient two-dimensional (2-D) films needed to transform the electronics industry.

No chance for bacteria on implants

Hip and dental implant operations are routine. But not entirely risk-free. They may result in infection that is difficult to control with oral or intravenous antibiotics. In such cases, the implant will probably need to be ...

Simulations reveal role of calcium in titanium implant acceptance

Titanium-based materials are widely used in medical implant technology. Coating the surface of titanium materials with biologically active molecules has recently shown promise to improve how cells adhere to implants and promote ...

Preventing dental implant infections

One million dental implants are inserted every year in Germany, and often they need to be replaced due to issues such as tissue infections caused by bacteria. In the future, these infections will be prevented thanks to a ...
