SCR CATALYST
Last month, the Catalysis business unit
of Clariant (Munich, Germany; www.
clariant.com) introduced an expansion of
its EnviCat series of catalysts to include
a high-performance catalyst for selective
catalytic reduction (SCR) to combat
oxides of nitrogen (NOx) emissions.
The catalyst, an extruded honeycomb
structured block made from a vanadiumbased
composite, is designed to facilitate
NOx reduction reactions in an oxidizing
atmosphere. With high selectivity, EnviCat
NOx significantly decreases NOx levels
using ammonia as a reducing agent for
the conversion of NOx pollutants into nitrogen
and water. EnviCat NOx SCR has
been demonstrated to effectively lower
NOx emissions from gas-fired exhaust
streams, and is suitable for a multitude of
industrial applications, says the company.
EnviCat NOx SCR is available in module
designs of varying lengths and cell
densities, is easily installed and can be
configured to a plant's particular dimensions.
The catalyst supports to achieve
plant-specific emission limit targets while
effectively controlling NH3 slip under lowto
mid-temperature operation.

New LEDs offer improved properties
F
lexible micro light-emitting
diodes (LEDs) - a sub100-µm
light source for red,
green and blue light - have
become a strong candidate for
the next-generation display due to
their low power consumption, fast
response, and flexibility. The previous
micro-LED technology had
drawbacks, such as poor efficiency,
low thermal reliability, and the lack
of
interconnection technology for
high-resolution micro-LED displays.
Now, a team from the Korea
Advanced Institute of Science and
Technology (Daejeon, South Korea;
www.kaist.ac.kr), led by professors
Keon Jae Lee and Daesoo Kim, has
developed
flexible
vertical
micro
LEDs (f-VLEDs) using anisotropicconductive-film
(ACF)-based transfer
and interconnection technology.
The Korean team has fabricated
an f-VLED array through the precise
alignment of ACF bonding. Those fVLEDs
achieved optical power denMore

sity of 30 mW/mm2) - three times
higher than that of lateral microLEDs
- and improved thermal reliability
and a lifetime of 100,000 h by
reducing heat generation within the
thin-film LEDs.
Lee says the f-VLED can be used
in low-power smart watches, mobile
displays and wearable lighting. These
devices are also suitable for biomedical
applications, such as controlling
the behavior of neuron cells and
brains, phototherapeutic treatment
and contact lens biosensors. In contrast
to the electrical stimulation that
activates all of the neurons in the
brain, these f-VLEDs can stimulate
specific excitatory or inhibitory neurons
within the localized cortical areas
of the brain, which allows for precise
analysis, high-resolution mapping,
and neuron modulation of brains.
Lee established a startup company,
Fronics, Inc., based on micro-LED
technology, and is seeking partners to
commercialize the technology.
