Sterilization Technology
Could Rapidly Disinfect
Disposable Face Masks
A new sterilization technology
could be the key to safely reusing
disposable face masks. Researchers
have figured out a way to rapidly
disinfect and electrostatically re -
charge N95 respirators, recovering
their original filtration efficiency
and protection capability
against COVID-19 and other airborne
diseases.
The technology could restore an N95 respirator's original
filtration efficiency of about 95 percent, even after 15 cycles
of treatment. The technology fights coronavirus by using
corona discharge - ambient atmospheric pressure plasma.
The technology works by simultaneously deactivating
pathogens on a mask and restoring its electrostatic charges. It
is nonthermal, meaning it doesn't require extra heating, and
doesn't require chemicals or contact, making it safe and convenient
to use. It's reusable and safer than ultraviolet (UV)
radiation and uses a low-power consumption technique -
requiring only 1.25 W of electricity.
The researchers are collaborating with a medical device
design company to turn their prototypes into products. They
are also working to develop handheld surface screening
devices to sterilize homes, hospitals, and other public areas.

'Healthy' Electric Current
Produced Inside Human Body
New nanotechnology has many
potential applications, including harvesting
clean energy to operate devices
implanted in the body through the
body's natural movements. The new
technology will make it possible to generate
electric currents and voltage within
the human body through the activation
of various organs by mechanical
force. The development involves a
new and very strong biological material
that is nontoxic and causes no
harm to the body's tissues.
The tripeptide - a very short molecule
called Hyp-Phe-Phe consisting
of only three amino acids - is capable
of a simple process of self-assembly of forming a collagenlike
helical structure that is flexible and boasts a strength similar
to that of the metal titanium. The researchers examined
whether the new material bears piezoelectricity.
The researchers created nanometric structures of the engineered
material, and with the help of advanced nanotechnology
tools, applied mechanical pressure on them. The experiment
revealed that the material does indeed produce electric currents
and voltage as a result of the pressure.
