#Geometrically Encoded Magnetic Sensors (GEMS) for High-resolution Remote Biological Sensing To date, most efforts to image highly localized biochemical conditions such as abnormal ph
"As a result, they can get strong, distinctive signals from very small dimensions at substantial depths or in other locations impossible to probe with optically based sensors.
The novel devices, called geometrically encoded magnetic sensors (GEMS), are microengineered metal-gel sandwiches about 5 to 10 times smaller than a single red blood cell, one of the smallest human cells.
the scientists tested the sensors in solutions of varying ph, in solutions with ion concentration gradients,
And some potential applications of the sensors may not be biological at all. But a long-term goal is to improve our techniques to the point at
But preliminary estimates by the experimenters indicate that the sensors can be reduced substantially from their current size,
"The idea is that you could design different sensors to measure different things, effectively measuring a panel of potential biomarkers simultaneously, rather than just one,

#Innovative Fabrication Technique for Hybrid Nanostructure Supercapacitor Electrode Offsetting this promise is the fact that,
Now two researchers from the S n. Bose National Centre for Basic Sciences, India, have developed a novel supercapacitor electrode based on a hybrid nanostructure made from a hybrid nickel oxide-iron oxide
from AIP Publishing, the researchers report the fabrication technique of the hybrid nanostructure electrode. They also demonstrate its superior performance compared to existing, non-hybrid supercapacitor electrodes.
Since nickel oxide and iron oxide are environmental friendly and cheap materials that are widely available in nature,
the novel electrode promises green and low-cost supercapacitors in future.""This hybrid electrode shows the superior electrochemical performance in terms of high capacitance the ability to store electrical charge of nearly 1415 farad per gram, high current density of 2. 5 ampere per gram,
low resistance and high power density,"said Ashutosh K. Singh, the primary researcher at the Department of Condensed Matter Physics and Material Sciences at the S n. Bose National Centre
the electrode could retain nearly 95 percent of initial capacitance after cycling or charging and discharging 3, 000 times."
"The Promise of Supercapacitorssupercapacitors are used electronic devices to store an extremely large amount of electrical charges.
reliable and potentially safer power source for electric and portable electronic devices in future, said Singh.
National Centre for Basic Sciences, mixed nickel oxide and iron oxide as a hybrid material and fabricated the novel core/shell nanostructure electrode."
"By changing the materials and morphologies of the electrode, one can manipulate the performance and quality of the supercapacitors,
and transporting ions through another material at the interface between electrode and electrolyte. Larger redox reaction surfaces are essential for achieving a higher power density for supercapacitors."
and electrochemical properties of the electrode, realizing high-performance supercapacitors,"Singh noted. How the New Electrode Performedusing techniques called cyclic voltammetry and galvanostatic charge/discharge methods,
Singh and Mandal studied the electrochemical properties of the hybrid material electrode. Comparing with the counterpart,
non-hybrid electrodes like nickel/nickel oxide and iron/iron oxide core/shell nanostructure electrodes, the hybrid material electrode demonstrated higher capacitance,
higher energy density and higher charging/discharging time.""For example, the current density of the hybrid electrode is three and 24 times higher than that of nickel/nickel oxide and iron/iron oxide electrodes, respectively,
"Singh said.""The comparative results show remarkable enrichment in the electrochemical activities of nickel/nickel oxide
and iron/iron oxide electrodes after combining them together, which suggests the hybrid electrode's better supercapacitive properties."
"One feature of Singh's fabrication technique is that it doesn't require extra binder materials.
According to Singh, binding materials are used commonly in the fabrication of carbon or graphene based supercapacitors for attaching redox active material on the current collector.
Without the mass of binding materials, the hybrid electrode is a good candidate to make lightweight supercapacitors."
and green supercapacitor electrodes for real life application, "Singh said. The researchers'next plan is to develop a whole supercapacitor device based on the hybrid electrode and test its functional performance,

antenna-rectifier diodes that convert light into DC current, have been built using multiwall carbon nanotubes with integrated nanoscale rectifiers.
The carbon nanotubes in the devices function as antennas for capturing light. When the light waves strike the nanotube antennas,
an oscillating charge is created that travels through the rectifier devices. A small direct current (DC) is created
a device that combines the functions of an antenna and a rectifier diode to convert light directly into DC current.
The antennas had to be sufficiently small enough for coupling optical wavelengths and the rectifier diode had to have the ability to operate rapidly to capture electromagnetic wave oscillations.
which is sufficient for ejecting electrons out of the carbon nanotube antennas upon the absorption of visible light Light in the form of oscillating waves interacts with nanotubes after going through the calcium-aluminum electrode.
This means the electrons flow in one direction towards the top electrode. The 10nm diode functions at such a high frequency due to the ultra-low capacitance,
which is in a few attofarads. rectenna is basically an antenna coupled to a diode, but when you move into the optical spectrum,
that usually means a nanoscale antenna coupled to a metal-insulator-metal diode. The closer you can get the antenna to the diode
the more efficient it is. So the ideal structure uses the antenna as one of the metals in the diode

#Unique, Optics-Based Tracking Sensor Created for Harmonica-Like Device Demonstrating the life changing technologies being developed as a result of Governor Andrew Cuomo leadership in fostering public-private partnership opportunities,
has developed a unique, optics-based tracking sensor for the amboxx, a harmonica-like device created by My Music Machines,
UNY Poly CNSE is proud to play a role in the development of this sensor
The device consists of a tilt sensor for octave selection a pressure sensor to produce sound,
and a position sensor to track the movement of the mouthpiece. As designed, the position slider had to make physical contact with a sensor,
however, and over time the slider wore out and failed. After hearing about SUNY Poly CNSE Professor and Head of the Nanobioscience Constellation Dr. Jim Castracane research related to novel sensors, the Jamboxx creators connected with Dr. Castracane who found that a Self
-Balancing Position Sensitive Detector (SBPSD) would make the Jamboxx more resistant to normal wear by avoiding a contact-method to track an input.
The Silicon-based linear detector was fabricated in SUNY Poly cleanrooms and is designed to track an LED,
which was added to the mouthpiece of the Jamboxx. After obtaining research grants from the New york state Trade Adjustment Assistance Center (NYSTAAC) and funds from My Music Machine, Inc. and support from SUNY Poly CNSE,
the SBPSD was developed without the need for any external electronics. It is extremely low cost, and provides excellent time response. aving heard that SUNY Poly CNSE leading-edge researchers are deeply involved with photonics-based sensors,
