is because the University will not
accept it.
"It's the same as approved in
prior years, not an administrative
failure on our end, but (the Uni-
versity) won't accept it," Jao said.
Jao added that if the chapter
is not re-instated, other student
organizations could also be at
risk.
"Any group that's honest
about their requirements will
be impacted if (the University)
applies it fairly," Jao said. "It will
affect Orthodox Jewish groups
on campus, (the) MuslimAssocia-
tion."
Jao said the group does not dis-
criminate, but believes it makes
sense for the leadership council
of the chapter to adhere to tradi-
tional Christian values.
"Every student, regardless of
beliefs, is welcome to attend meet-
ings," he said. "But we believe it
makes sense for a religious group
to select religious leaders."
Sara Chang, a local recruiter
for InterVarsity, said the chapter
has worked with the University
since 2010 to be in compliance
with the University's standards.
"Our plans are that we would
be able to work with the Uni-
versity and have open, honest
discussion about nature of non-
discrimination policy, asking
them that they would revise it to
be as it stands but also give room
for religious groups to choose
religious leaders," Chang said.
According to the InterVaristy
website, . other chapters have
faced similar obstacles. The group
was derecognized after the 2010
U.S. Supreme Court decision,
Christian Legal Society v. Marti-
nez, which allows public institu-
tions to require that on-campus
groups accept all students regard-
less of their "status" or "beliefs."*
"InterVarsity will continue
its ministry at the University of
Michigan Ann Arbor campus
regardless of whether our chap-
ters are officially recognized, but
our desire is to maintain a posi-
tive relationship with the univer-
sity," a statement on the group's
website reads. "We are currently
working with university officials
a to resolve this situation."

HACKATHON
From Page 1A
the Hackathon as a whole.
MHacks eclipsed PennApps,
a semi-annual hackathon held at
the University of Pennsylvania, to
become the most well-attended
college hackathon in the nation.
In January, PennApps had over
450 attendees.
The initial count for Mhacks:
unclear. But Fontenot's original
count was 521 people. About 20
to 30 people came after that, and
a facilities manager at Palmer
Commons counted about 600
people. In fact, there were so
many attendees that 20 to 30
were temporarily moved to the
UGLi, Fontenot noted.
Still, he said that it was more
than just the sheer number
of hackers that attended that
made the event a success. The
evidence: a huge number of
toothbrushes and toothpaste
PRINTING
From Page 1A
with ink or chemicals, his lab
uses precisely inscribed grooves
to yield an observable color.
"Rather than using these chem-
icals, you could basically emboss
the structure - a very'green' print
technology,"Guo said.
Not only would printed prod-
ucts be more environmentally
friendly, they would also not be as
prone to fading that occurs with
current coloring techniques.
"(Current print companies are)
using huge amounts of chemi-
cals," he said. "A press company
is not exactly the greenest place
... In the future, this can all be
done using structural color and it
would be long lasting."
Unlike traditional color, which
is produced when molecules
absorb light, this new process,
called "structural color," is the
result of nanocavities trapping
light at specific wavelengths that
depend on the cavities' depths.
Most importantly, the cavities
themselves have no chemically
imposed color. Their structure
alone allows them to display
color to an observer.
"By making a structure rather
than using these molecules, it's
purely a physical effect," said Guo.
This same phenomenon can
be seen in nature, such as the
colors in the feathers of peacocks
and the wings of some species of
butterflies, Guo said.
By varying the depth of the
cavity, the researchers can create
many different colors. Because
each depthcorrespondsto adiffer-
ent observable color, Guo referred
to this as a selective property."
The cavities are manufactured
through an extremely precise
nano-imprinttechnique in the lab.
"Wecannotevenseethese(nano-
cavities) with an ordinary micro-
scope because (the size) is beyond
the diffractionlimit,"Guosaid.
Guo's lab has been work-
ing on similar technology for
several years. However, previ-
ous attempts have been "angle
dependent," meaning that the
observable color would change
based on the viewing angle. This
new development has almost
completely alleviated this prob-
lem, allowing the image to be

viewed at any angle without
changing color.
In addition to green printing,
this technology has potential
applications in anti-counterfeit-
ingefforts becauseofthe property
that makes it difficult to replicate.
"These structures are really

University's Center for Entre-
preneurship.
At the final ceremony, 10 teams
out of a total of 123 demonstrated
the apps they developed. Two
btothers, Ali and Ehsan Razfar
from the University of Illinois,
won the grand prize (among oth-
ers) including two trips to Cali-
fornia for hacking competitions
and more than $1,000.
The Razfars' app, Speakeasy,

er in one language and have it

language - plus it translates
tiny ... and extremely hard to
reproduce," Guo said. "In addi-
tion, you can only see this kind of
structure when the electrical field
is perpendicular to the grating
... That kind of property is much
more difficult to reproduce."
The lab looks forward to
applications in the development
of a colored e-book, similar to
a Kindle, which would have ari
extremely low power usage.
"If you make these sub-pixels
colored - and control them on
and off - you could get a reflec-
tive e-book," Guo said. "If it can
stay on and doesn't consume
much power, that's what the orig-
inal e-book was aiming for. The
stand power could be amonth."
Rackham student Yi-Kuei Wu
has worked extensively with Guo
on the project. Current discus-
sions with industry suggest that
this technology will come to mar-
ket in the near future, he said.
"Traditional LCD is strug-
gling with some of the issues of
(current) color filters," Wu said.
"I worked with Samsung Elec-
tronics to get a lot of practical
ideas ... We are trying to push
this pretty hard with Samsung."

color filters account for 30 per-
cent of the cost of device pro-
duction, not to mention a large
portion of the energy usage.

"We are pushing towards
some real applications," Zhang
said. "(We fabricated), five dif-
ferent colors in a single sample ...

ors for reflective color filters."
