around which the microparticles gathered. The lasing created
by these microparticle clusters could be turned on and off by
changing the intensity of the external laser, which in turn controlled
the size and density of the cluster.
The team also showed how the lasing cluster could be transferred
in space by heating different Janus particles, demonstrating
the adaptability of the system. Janus particles can also
collaborate, creating clusters that have properties beyond the
simple adding of two clusters, such as changing their shape and
boosting their lasing power.
Co-Lead Author Dr. Giorgio Volpe, from the Department
of Chemistry at UCL, said: " Nowadays, lasers are used as a
matter of course in medicine, telecommunications, and also
in industrial production. Embodying lasers with life-like
properties will enable the development of robust, autonomous,
and durable next-generation materials and devices
for sensing applications, non-conventional computing, novel
light sources and displays. "
Next, the team will study how to improve the lasers' autonomous
behavior to render them even more life-like. A first application
of the technology could be for next-generation electronic
inks for smart displays.

ASA instrumentation is at risk for contamination from dusty
space environments. Additionally, contamination from water
and ice buildup can affect instrumentation function. Researchers
at the Goddard Space Flight Center have developed a viable dust,
water, and ice mitigation optical coating for space flight, aeronautical,

coating prevents contamination on sensitive surfaces, like optics,
that cannot be cleaned during space missions.
In addition to previous LOTUS coating formulations, an additional
optical formulation may be applied via vacuum deposition.
This coating forms a top layer and may be applied in different
thicknesses that serve to enhance its hydrophobic properties.
The vacuum deposited material may comprise fluorinated ethylene
propylene or a similar material. This coating is transparent
and can be used on optical components or any other applications
requiring a clear coating.
Some of the key features of the coatings are that it adheres to a
variety of common materials, prevents dust and water-based contamination
as well as that it's optically clear and extremely scalable.
The technology has several potential applications including remote
sensing, earth imaging, and communications.
NASA is actively seeking licensees to commercialize this technology.

or call at 202-358-7432 to initiate
licensing discussions. For more information, visit https://
