Previous success in the field of ultra-lightweight"aerogel monoliths"has relied largely on the use of precious gold and silver nanowires.
"Aerogel monoliths are like kitchen sponges but ours are made of ultra fine copper nanowires, using a fabrication process called freeze drying,
"The copper aerogel monoliths are conductive and could be embedded further into polymeric elastomers extremely flexible,
"Despite its conductivity, copper's tendency to oxidation and the poor mechanical stability of copper nanowire aerogel monoliths mean its potential has been unexplored largely.
The researchers found that adding a trace amount of poly (vinyl alcohol)( PVA) to their aerogels substantially improved their mechanical strength
the aerogels could be used to make electrically conductive rubber materials without the need for any prewiring.
the researchers noted that devices using their copper-based aerogels were not quite as sensitive as those using gold nanowires,
At present therapeutic antibodies are purified generally by a technique known as protein A affinity chromatography. The process yields a high purification factorypically 99 per centut it is slow thereby creating a severe productivity bottleneck.

which is used now in the medical field to detect biomarkers in the early stages of disease.
A key component is the detection of biomarkers, proteins in blood or saliva, for example, whose presence or abnormal concentration is caused by a disease.
Biomarkers can indicate the presence of diseases long before the appearance of symptoms. However, currently the detection of these molecules still requires specialised laboratories
When the nanoantennas studded with the bioreceptors are incubated in a solution that contains the biomarkers to be detected,
they show the Raman fingerprints of both the bioreceptor and the biomarker, as Gucciardi points out.
"We found that for a material as light and sparse as aerogel a kind of glass foam,

and performance can be achieved by the single chip or monolithic integration of micro gas chromatography components"he added.

#Biometric Security: From Selfies To Walking Gaits Oren Levy is CEO of Zooz. The payments industry, facing the risk of increasingly sophisticated cyberattacks
and various types of credit card fraud, has begun incorporating various types of biometric technology to enhance security
Mastercard imminent transition to biometrics was preceded by Apple Pay launching in October 2014 of a biometric payment technology based on fingerprint ID. The newest iphone models are equipped with Apple Touch
the stage seems to be set for the large-scale adoption of biometric technology. While the payments industry is currently working full steam on various forms of biometric technology aimed at thwarting ever-increasing security breaches in payments technologies,
biometrics have been around for quite a while, and the technologies take different forms. Back in 1665, Marcello Malphighi was credited with the discovery of the unique patterns of fingerprints.
In 1880, Dr. Henry Faulds, a Scottish surgeon, published a paper on how fingerprints can be used for identification.
Today, most mainstream biometric recognition is based on fingerprint, palm, iris, facial and voice recognition. Alongside these physiological recognition methods come behavioral biometrics that can recognize a person based on his
or her typing rhythm (called keystroke dynamics) or walking gait (which is based on an individual movement patterns).
Behavioral biometrics are considered currently less reliable than the physiological system, but as this technology is still in its early stages,
Many law enforcement agencies and governments are already using biometric technology because it affords a higher level of security against cyber attacks than other protection methods.
The newfound availability of biometric technology for mobile and cloud-based platforms raises the security bar further.
Nevertheless, while there are many who hail biometrics as a game changer, others believe that in its current form it does not provide the necessary level of security to prevent identity theft.
Qualcomm Technologies recently announced the development of the first comprehensive mobile biometric solution based on ultrasonic technology.
which would prevent hackers from replicating fingerprints or other biometric methods. This type of technology would have the ability to detect
if the real biometric is physically present. Researchers are seeking to create an optimal arrangement of biometrics
and tokenization layers that will ensure high-level security. The ultimate solution technology may involve using a mixture of several forms of biometric authentication,
such as skin temperature, palm veins and voice recognition. Increased security is not the only consideration
when discussing the advantages of biometrics. Imagine a world in which there is no need to remember a slew of passwords and PINS for various sites.
biometrics could enable merchants to identify valued customers, as well as known shoplifters, as soon as they enter a brick-and-mortar store.
Charges would automatically be referred to the customer biometric-based records. This type of technology could merge with the personalized omni-channel shopping experience that merchants are currently striving to create for their customers.
cloud, banking and payments industries must prepare themselves for the shift from traditional authentication methods to the new biometric systems.
Once biometric technology is perfected and becomes cost-effective, its widespread deployment could save merchants and banks millions of dollars and provide high-level protection against cyber attacks.
However, when it comes to the extensive use of biometrics in the payments industry, the biggest hurdle to overcome is widespread adoption.
Retailers and consumers will need to concur on the best form of biometric payments before passwords can become obsolete s
