AROUND the industry
a papeR MIcRoScope FoR tHe woRld
Manu Prakash and his Stanford University
students have developed a microscope out
of a flat sheet of paper, a watch battery,
an LED and optical units. When folded
together-origami fashion-the result is a
functional instrument with the resolution
of 800 nanometers, capable of magnifying
an object up to 2,000 times.
Costing less than a dollar in parts, it is small enough to fit in a pocket yet extremely
durable. It can also project an image on any surface, allowing a larger group of people to
view it simultaneously. Its minimalistic design is geared towards applications in global
health, field based citizen science and K12-science education.
Prakash hopes that because Foldscope is so cheap to manufacture and easy to assemble,
that everyone will have access to the world of microscopy.
SMaRt NaNo beadS detect aNd RepaIR coRRoSIoN
Using nanotechnology, scientists as
Battelle, Columbus, OH, USA, have developed a tiny bead that not only detects corrosion but also helps heal the microscopic
cracks that rust creates.
The Smart Corrosion Detector beads
look like a fine, whitish powder that can
be mixed with coatings used to protect
pipelines and other critical infrastructure subject to corrosion. The self-healing
smart beads detect and reveal corrosion forming on metal before it is visible to the naked eye.
Once activated, the 20 to 50 micron beads release a proprietary chemical that fills the cracks.
doubleS SINce 1990
A total of 63.5 percent of
paper consumed in the U.S.
was recovered for recycling in
2013, according to a report by
the American Forest and Paper
Association. The annual paper
recovery rate has nearly doubled
since 1990, and the industry has
set a goal to exceed 70 percent
paper recovery by 2020 as part
of its Better Practices, Better
Planet 2020 sustainability
Employees from Georgia-Pacific's consumer products operations in Crossett,
Ark., and Muskogee, Okla., USA, loaded
six tractor-trailers with bath tissue and
paper towels destined for relief agencies working onsite in communities in
Arkansas and Mississippi recently damaged by devastating tornadoes.
cleaN up MajoR SpIllS
A new nanosponge from Empa Wood
Research, Switzerland, may help clean
up future oil spills.
In an oil spill, a typical sponge will
absorb water along with oil, sink underwater and lose most of its absorption capabilities. To prevent this, Empa researchers
modified the chemical properties of nanocellulose by admixing a reactive alkoxysilane molecule into the gel before freeze
drying. As a result, the sponge will no
longer absorb water and can float on the
surface where it will bind with any type
