Korean Scientists Propose New Environment-Friendly
Approach for Soil Treatment
|
|
Ongoing climate change has made the development of
new renewable energy sources the need of the hour.
Hydrogen production through water-splitting
reactions is one of the most promising options, but
the commercial viability of current technologies is
limited. Recently, researchers from Ajou University
have developed a novel, dual textured
heterostructure that provides key insights into the
design of efficient water-splitting electrodes

Artificial Muscle Actuators: The Key to an Immersive
Augmented Reality Experience
|
|
Wearable optical devices find use in several fields,
ranging from gaming to medicine. To improve on the
immersive visual experience that current devices
offer, researchers from Ajou University have
developed an all-new compliant amplified shape
memory alloy actuator (CASA). Its elliptic
configuration and compliant structure amplify
actuation strain and retain power density. Moreover,
the artificial muscle-like actuator is light and
compact. The researchers also demonstrate CASA-based
prototype augmented reality glasses and two-way
communication 3D-touch gloves.

New Classification for Flat Bands to Allow Future
Design of Quantum Devices
|
|
Indium–gallium–zinc oxide (IGZO) semiconductors are
promising as active components in thin-film
transistors owing to their favorable electrical and
optical properties. However, uncontrolled oxygen
vacancies in IGZO can degrade device performance
through negative shifts in the transistor threshold
voltage (Vth), which should ideally be close to
zero. Now, researchers from Ajou University have
realized a rapid modulation of Vth using UV
irradiation, opening doors to reliable oxide devices
with high mobility and large-area transparency.

Advancing Organic Light Emitting Diode Displays with
a Novel Color Conversion Method
|
|
Existing blue organic light emitting diode (BOLED)
displays use inkjet printing-based color filters for
color conversion, resulting in a trade-off between
perfect conversion and brightness. To tackle this,
researchers from Ajou University have now developed
luminescent films that are extremely thin compared
to inkjet printing, can completely convert colors,
and enhance light intensity. The deposited films
could potentially be applied to quantum dot-enhanced
BOLED displays soon.
