#Black phosphorus surges ahead of graphene A Korean team of scientists tune black phosphorus band gap to form a superior conductor,
allowing for the application to be produced mass for electronic and optoelectronics devices. The research team operating out of Pohang University of Science and Technology (POSTECH),
affiliated with the Institute for Basic Science (IBS) Center for Artificial Low Dimensional Electronic systems (CALDES), reported a tunable band gap in black phosphorus (BP),
This research outcome potentially allows for great flexibility in the design and optimization of electronic and optoelectronic devices like solar panels and telecommunication lasers.
This amalgamation makes it a terrifically attractive material to apply to scientific developments in a wide variety of fields, such as electronics, aerospace and sports.
graphene has no band gap. Stepping stones to a Unique Statea material band gap is fundamental to determining its electrical conductivity.
Imagine two river crossings, one with tightly-packed stepping-stones, and the other with large gaps between stones.
A band gap is much the same; the smaller the gap the more efficiently the current can move across the material and the stronger the current.
Graphene has a band gap of zero in its natural state, however, and so acts like a conductor;
the semiconductor potential can be realized because the conductivity can be shut off, even at low temperatures. This obviously dilutes its appeal as a semiconductor,
as shutting off conductivity is a vital part of a semiconductor function. Birth of a Revolutionphosphorus is the fifteenth element in the periodic table
and lends its name to an entire class of compounds. Indeed it could be considered an archetype of chemistry itself.
Like graphene, BP is a semiconductor and also cheap to mass produce. The one big difference between the two is BP natural band gap
allowing the material to switch its electrical current on and off. The research team tested on few layers of BP called phosphorene
which is required what we to tune the size of the band gap. his process of transferring electrons is known as doping
which tuned the band gap allowing the valence and conductive bands to move closer together, effectively lowering the band gap
and drastically altering it to a value between 0. 0 0. 6 Electron volt (ev) from its original intrinsic value of 0. 35 ev.
It more efficient in its natural state than black phosphorus but it difficult to open its band gap;
therefore we tuned BP band gap to resemble the natural state of graphene, a unique state of matter that is different from conventional semiconductors. he potential for this new improved form of black phosphorus is beyond anything the Korean team hoped for,
and very soon it could potentially be applied to several sectors including engineering where electrical engineers can adjust the band gap
and create devises with the exact behavior desired. The 2-D revolution, it seems, has arrived and is here for the long run.

#First realization of an electric circuit with a magnetic insulator using spin waves Abstract: Researchers at the University of Groningen, Utrecht University, the Universit de Bretagne Occidentale and the FOM Foundation have found that it is possible to make an electric circuit with a magnetic insulator.
This was deemed first impossible. The circuit is realized using spin waves: wavelike perturbations in the magnetic properties of a material.
Their discovery is interesting for the development of novel, energy-efficient electronic devices, particularly integrated circuits. A device based on spin waves could theoretically operate more efficiently than ordinary electronic circuits.
The results of their research will be published online in Nature Physics on Monday 14 september. In our current electronic equipment, information is transported via the motion of electrons.
In this scheme, the charge of the electron is used to transmit a signal. In a magnetic insulator, a spin wave is used instead.
Duine from Utrecht University have succeeded to use spin waves in an electric circuit by carefully designing the device geometry.
and hence enables the spin waves to be used in an electric circuit. The spin wave circuit that the researchers built,

classical dipole patch antennas have been used.""Now, our technology introduces'metasurfaces'that are much better energy collectors than classical antennas,
"explained Omar M. Ramahi, professor of electrical and computer engineering. Metasurfaces are formed by etching the surface of a material with an elegant pattern of periodic shapes.
"Conventional antennas can channel electromagnetic energy to a load --but at much lower energy absorption efficiency levels,"said Ramahi."
"Our research enables significantly higher energy absorption than classical antennas, "Ramahi said.""This results in a significant reduction of the energy harvesting surface footprint.

#Putting Sensors In Bridges And Tunnels Could Make Their Walls Talk Trying to get a building to tell you how it feeling is,
by creating various sensors to fit inside buildings, tunnels, and bridges. With the feedback collected from these sensors,
inspectors will have a better understanding of how a city's infrastructure is holding up GENESI is an awkward acronym for reen sensonr NETWORKS for Structural monitoring.
GENESI puts sensors into a city's various structures to let them"communicate"their status. These sensors include ibrating strain gauges, displacement meters, pressure sensors, temperature sensors,
and soil moisture sensors.""To conserve power, they have energy harvesting capabilities, and engineers can periodically wake them up to get fresh readings from the sensors and check for any changes.
One of GENESI two pilot projects is a testbed in the tunnels of Rome underground rail system,
where wire sensors that pick up strain from vibration were placed inside certain concrete segments. Data loggers record the data,
transmitting the information to a wireless setup and relay system, which then sends it out via cell networks to a remote server.
but powering sensors--even really efficient sensors--requires some form of electric charging or battery replacement.
But each GENESI node and sensor includes a miniature wind turbine that harvests energy from passing trains.
For all other sensors, whether tucked away in tunnel walls or nestled in dark unlit crevices under bridges,
#Open-source Soil Sensors: Vinduino As California fourth straight year of drought forces farmers to cut back on water use,
one California vineyard-owner has taken a DIY approach to creating a sensor-driven water conservation system.
The project so far includes instructions for making your own soil moisture sensors (based on the gypsum mineral found in plaster of paris;
building a handheld Arduino-based device for taking sensor readings; and creating Arduino-based irrigation valves,
water pressure sensors and data loggers for controlling and monitoring the vineyard irrigation system. In prototype stage is networked a,
solar-powered sensor reading station that can report Vinduino sensor data via the Thingspeak platform.
Van der Lee future plans include designing a network hub for collecting readings from multiple sensor stations,
Van der Lee says that one of his primary motivations for building Vinduino was to innovate on commercial soil monitoring systems that typically rely on readings from a single sensor.
Vinduino uses three sensors at different depths to get a better handle on the way water moves through the soil at each measurement point.
together with low cost gypsum soil moisture sensors, provides all that. heck out the video below to learn more.
Another possible application is in sensors that measure magnetic fields. The results have been published in Nature Communications c

Through a new semiconductor material, gallium nitride (Gan. Already being used in LED light bulbs, television and computer displays,
and transistors found in all the computing devices of our modern world. CEI, through Gan, hopes to change because not only is the material more efficient in light emission,
it also handles power more efficiently than any silicon-based transistor. Over nine years CEI has been perfecting Gan
and today it can outperform silicon providing 1/10th the resistance of silicon transistors. This means faster switches
and other electronic devices eliminating the clunky brick that is commonly comes with a device's power cord.
So why aren't we seeing a flood of electronic devices on the market made from Gan now?

Sensor-based irrigation systems show potential to increase greenhouse profitability Wireless sensor-based irrigation systems can offer significant benefits to greenhouse operators.
Advances in sensor technology and increased understanding of plant physiology have made it possible for greenhouse growers to use water content sensors to accurately determine irrigation timing and application rates in soilless substrates.
The wireless sensor systems provide more accurate measurements of substrate moisture than qualitative methods and can save irrigation water labor energy and fertilizer.
The authors of a report published in Horttechnology said that the use of sensor-based irrigation technology can also accelerate container and greenhouse plant production time.
Sensor-based irrigation systems substitute capital for water and associated inputs such as energy labor and fertilizer the authors explained.
The scientists found that controlling irrigation using data from moisture sensors led to substantial reductions in both production time and crop losses.
Calculations showed that annualized profit under the wireless sensor system was over 1. 5 times more than under the nursery's standard practice
even if efficiency gains are not as high as those in the study controlling irrigation using wireless sensor systems is likely to increase profitability substantially.
They added that wireless sensor systems can have environmental benefits as well as the economic benefits shown in the study.
