SHAPING THE FUTURE OF GREEN NANOTECHNOLOGY

We work with van der Waals materials known as transition metal dichalcogenides (TMDs). TMDs are an emerging class of materials for new research frontiers and future applications.

Nanopatterning can change TMD properties in a structure-dependent manner. Our service is to fabricate and deliver such structures.

APPLICATIONS

MATERIAL FEATURES & APPLICATIONS FOR INDUSTRY

Molybdenum disulfide (MoS2) and tungsten disulfide (WS2) are semiconducting analogs of famous graphene. Especially MoS2 is used in industry already now, as a catalyst for oil desulfurization reaction and as a lubricant additive.

We were first to discover a way to significantly improve the properties of natural MoS2 by introducing perfect and highly controllable edges in the material.

READ MORE ABOUT APPLICATIONS

ELECTRONICS

Zigzag edges that we create are ferromagnetic and metallic, unlike semiconducting planes.

SENSORS

Exposed edges allow to improve the sensitivity of sensors.

SCALABILITY

The material can be prepared in large quantities and in different forms, including colloidal solutions, sprays, and powders.

CATALYSIS

Our method allows us to significantly improve catalytic activity by exposing relevant zigzag edges in massive amounts.

MECHANICS

TMDs are highly bendable and mechanically strong.

OPTICS

The color of the reflected or transmitted light can be controlled across the entire visible range – from blue to red.

ABOUT PRODUCTION

OPTICAL MICROSCOPY IMAGES

Nanostructured TMDs support vivid colors across the whole visible spectrum and beyond. An example of true-color optical images of nanopatterned TMD is shown here.

Publications

We have a long-term experience working with TMDs and their nanopatterning. Our work is based on several high-profile scientific publications, including:

As well as a number of on-going activities in our Research Group.
