Gallium nitride (Gan) and Indium Gallium nitride (Ingan) Technology Targets Fast-growing Markets for Wearable Vision Systems Abstract:
Leti researchers have developed gallium nitride (Gan) and indium gallium nitride (Ingan) LED TECHNOLOGY for producing high-brightness, emissive microdisplays for these uses,
which are expected to grow dramatically in the next three to five years. For example, the global research firm Marketsandmarkets forecasts the market for head up displays alone to grow from $1. 37 billion in 2012 to $8. 36 billion in 2020. urrently available microdisplays for both head-mounted
and 3d heterogeneous integration of such LED arrays on CMOS active-matrices. These innovations make it possible to produce a brightness of 1 million cd/m for monochrome devices
The electromagnetic radiation discharged by electronic equipment and devices is known to hinder their smooth operation. Conventional materials used today to shield from incoming electromagnetic waves tend to be sheets of metal or composites,
They're widely expected to improve energy storage, sensors, nanoelectronics, catalysis and separations, but graphene aerogels are prohibitively expensive and difficult to produce for large-scale applications because of the complicated purification
Further potential applications could also be flexible and stretchable electronic devices, luminescent actuators, batteries, smart cloths or sacrificial templates for the growth of new materials.
Molecular machines, novel sensors, bionic materials, quantum computers, advanced therapies and much more can emerge from this endeavour.

"Ionics, ion-based data processing and energy conversion, is the electronics of the future, "says Jennifer Rupp, a professor of Electrochemical Materials at ETH Zurich,
for example, in lambda sensors of automotive catalytic converters and solid oxide fuel cells. The ETH professor is convinced that the industrial importance of these materials will even further increase-for example, in gas sensors, new classes of data storage and computer circuits,
and in the conversion of chemical energy into electrical energy and vice versa. One of the most important research questions in Rupp's field currently is how to optimise these materials,
Electrode design affects buckling profilethe researchers also found that the arrangement of the electrodes affects the buckling profile of the ceramic membrane
This supports the development of future gas sensors, ion-based data storage and micro energy converters, such as fuel cells-and potentially a range of other as yet unknown applications in the promising field of ionics.##

#New Sensors Measure Blood Anticoagulation Drug Iranian researchers from Isfahan University of Technology produced a highly sensitive and accurate sensor
The sensor was produced through a simple and cost-effective method and its application does not require advanced skills.
a simple but very sensitive sensor based on fluorescence spectroscopy was presented by using cadmium telluride quantum dots to quickly measure protamine drug.
Taking into account the fact that this sensor presents a simple and quick method for the measurement of protamine,
In addition to its high speed, this sensor minimizes environmental pollution due to the use of very low concentration of quantum dots in the production of the sensor and the lack of the need for toxic and organic solvents.
Researchers believe that the results of the research can be commercialized due to the advantages of the sensor including quick and fast measurement,

#Iranian Scientists Use Gas Sensor to Detect Hydrogen Iranian researchers designed a sensor with the capability of rapidly detecting the amount of hydrogen existing in the environment.
This sensor can detect the leak of hydrogen in hazardous environment which can prevent the explosion.
Hydrogen sensors are convertors that create electrical signal by adsorbing hydrogen molecules, which depends on the concentration of the hydrogen.
In this research, a capacitor MOS sensor was produced that detects the leak of hydrogen at explosive level (4 vol. percent) in less than two minutes.
Capacitor sensors detect any change in the environment through changing the electrical capacity of the capacitor.
The advantages of these sensors over other types of sensors are stability long lifetime and low response time.
For instance, this sensor can be used in the monitoring of hydrogen concentration during the production of ammonia, methanol and hydration of hydrocarbons.
Among other applications of this sensor, mention can be made of desulfurization of petroleum products, production of jet fuel and launching of aircrafts and other aerospace applications.
This research also studies the effect of the thickness of oxide layers in the sensor structure on its properties and performance.
the sensor detects hydrogen in a shorter period of time as the thickness of oxide layer decreases.
Response time has been calculated to be 84 seconds for a capacitor sensor with oxide layer thickness of 28 nanometers.
Results of the research have been published in Sensors and Actuators B: Chemical, vol. 216, issue 1, 2015, pp. 367-373 3
