Triboelectric Nanogenerators Boost Mass Spectrometry Performance

Scientists Successfully Boost the Mass Spectrometry Performance by Using Tribolectric Nanogenrators

The most basic problem which surfaces in the entire consumer electronics device is the power consumption. We are actively looking for such kind of power source which doesn’t put a hole in our pocket and helps in getting performance out of the device. Researchers have come with a solution by developing the triboelectric nanogenerators (TENG) which will help in converting the mechanical energy from the environment to electricity. And this electricity will be more than enough to power some of the small devices which include the sensors and consumer electronics products.

The team behind this remarkable technology

This technology has been developed by researchers at the Georgia Institute of Technology which can bring a trend of replacing the traditional power supplies with the TENG device for charging. Though in this case the TENG devices will be used of charging the molecules in the spectrometers and the research has shown that it take the sensitivity of it to an unimaginable level which is good in every way. Scientists have conducted few experiments on the smaller samples in order to understand the full extent of the applications of the TENG technology.

During their research it was found that this technology requires further study the TENG offers unique aspects in its output which has a remarkable high voltage as well as controlled current. This means that the TENG can help in making incredible improvements in the ionization process and later on increased voltage speed can be easily applied to the instrument without even damaging it. This research has already been published in the journal Nature Nanotechnology and quite incidentally this research has been supported by the Natural Science Foundation as well as Department of Energy and NASA astrology Program. Researchers has been modest about their astonishing technological discovery based on the nanogenerators by stating that it is quite new and it is being used in a very controlled manner in order to charge the molecules.

The remarkable finding of the research

Researchers have made use of this technology in the electrospray ionization and plasma discharge ionization wherein they have been able to generate singular polarity as well as alternating polarity of ion pulses. Researchers have successfully measured the voltage level present in the mass spec ionizer to be between the 6000 to 8000 volts. It is a great achievement given the fact that the standard iconizer presently in use can only operate at less than 1500 volts.

The future application of the TENG technology

Researchers have retrofitted the tech technology to existing mass spectrometers and this has been done in the lab with great success. Their research has already been published in some of the journals and researchers are hopeful that more number of people starting making use of the TENG technology in not just the mass spectrometry but even other areas. This nanogenerators based technology will certainly help in getting more power for our daily use devices without spending huge amount of time and money.

Why Your Smartphone's Fingerprint Scanner is not as Secure as You Might Think

Master Fingerprint – Less Secure 

Researchers who had developed `master fingerprints’ with the capability of tricking the sensors, are of the belief that smartphone fingerprint scanners tend to be less secure then led to believe. They were capable of bypassing fingerprint readers that had been utilised in unlocking phones, log-in to apps and in making payments, utilising fake fingerprints developed by using patterns located across several real prints.

 This discovery from New York University and Michigan State University gave rise to query regarding security of the popular utilised technology. The researchers were capable of creating a set of `master prints which could trick a scanner up to 65% of the time.

Fingerprint scanners are considered to be more secured than depending on passcodes in unlocking smartphones. According to Apple the Touch ID scanner utilised on the iPhone tends to have only a one in 50,000 chance of matching with somebody’s finger.

Though the researcher state that they had tested only their discoveries in computer simulation instead of real smartphones, they cautioned that the technology creating artificial physical fingerprints had been refining quickly.

Adequate Resemblance Between Various Prints

Since in present days the fingerprint readers on smartphones seem to be comparatively small, they usually tend to scan various areas of a fingerprint making sure that just one press of a finger or thumb could effectively trigger the sensor.

 Since several users tend to register numerous fingerprints on a device and there are often dozens of various incomplete prints registered on a phone, only one of these incomplete scans could be a match for the sensor in unlocking a phone. According to Nasir Memom of NYU, one of the authors of the study that had been published in IEEE Transactions on Information Forensics &Security had commented that there is a greater opportunity of falsely matching a partial print than a full one and most devices tend to depend only on partials for the purpose of identification.

In spite of the human fingerprints being comparatively exclusive, researchers have stated that they had discovered adequate resemblances between various prints in creating synthetic master prints which could effectively replicate several fingerprints of the users.

Hosted Other Authentication Systems 

Since the phones seem to typically permit several attempts before deactivating the fingerprint scanner and needs a passcode, Mr. Memon had stated that one could create a glove with five different fingerprints which would get into almost half of iPhone before the five attempts permitted, tend to expire.

Irrespective of the well-known trust in fingerprint scanners, some of the phone manufacturers had hosted other authentication systems. The new Galaxy S8 phone of Samsung is said to have an iris scanner together with facial recognition though the latter is shown to have been fooled by images. Moreover, smartphone passcodes have also portrayed to be susceptible to cracking.

There seems to be a one in 10,000 chance of guessing a four-figure passcode though researchers from Newcastle University have shown that the motion sensors in a phone could disclose the numeric codes by identifying how a phone tends to move when certain areas of the screen are pressed.

Japanese researchers had earlier cautioned that posing with peace signs in images could be adequate for hackers in copying your fingerprints and then unlock a fingerprint secured phone.

Researchers Print Promising Two-Dimensional Transistors

Researchers just printed two dimensional transistors successfully

If you are wondering what transistors then please note it is essentially a semiconductor devices which helping amplifying and switching the electronic signals or electric power as a whole. It plays a vital in almost all the electronics products which are available in the market and without it you can’t even think of devices performing the way they are. Some of the researchers from AMBER and Trinity College in Dublin have successfully created printed transistors that consist of only two dimensional nanomaterials. The best thing about this innovation is that no one has done it before and the 2d materials used in comes loaded promising electronic properties which is extremely low cost in nature.
This research does have some of the incredible application potential which can’t be explained to its fullest. For example in future the food packaging industry can make use of it bring a digital countdown which will alert the users about the health of the food and placing it on wine bottle can help in showing whether wine is kept at the optimum temperature or not. Their finding has already been published in the Science magazine April issue.

 

The team behind this technology

Using the standard printing technique of combining the grapheme nanosheets which includes the electrodes with two other nanomaterials namely boron nitride and tungsten diselenide. The two most important parts of the transistors is called the channel and separator and researchers has been able to print it on a nanosheet thereby coming up with a working transistor.

The team of researchers consisted of Trinity College professors namely Jonathan Coleman and Georg Duesberg. Coleman has shed light on the future possibility of creating or combining together highly complex device by conducting, semiconducting as well as insulating the 2D nanomaterials. But during their research they simply focused on printing the transistors which can work as electric switches into the modern computing with ease and grace. 

New method indulge in testing without even touching

Earlier the chemical vapor deposition were used to develop the two dimensional transistors. Using this particular the transistors were great at performance but the method itself was quite expensive.

While the printable electronics brings a new way of printing components which are mostly based on the carbon based molecules at extremely low cost and get an amazing performance out of it at the same time. It is worth noting that carbon based molecules does have its own share instability and performance limitations but it is still better than the chemical vapor deposition.

A single nanosheet can do much better

Researchers has made use of many different nanosheets of completely varying size in order to get best combination available for the printing their transistors. When the printing process was initiated researchers simply deposited the nanosheets over one another in random fashion and it was found that the conductivity present within the nanosheets was just good for the job.

So the next job for the researchers is to come with a single nanosheet which will help in printing such 2D structures which offers better performance than the current one.

Google Chrome's most frustrating feature is BACK

Google Chrome is bringing back the most annoying feature

There is a very annoying feature built right into the Google Chrome which uses to leave users frustrated beyond words. Just last year Google finally said goodbye to its annoying feature which allowed users to make use of the backspace key as a smart function to return on previous page.
The major reason why Google went ahead removed this feature from the Google Chrome is that users has complained that they happen to lose data whenever they hit backspace while filling out the online forms. When a user made use of the backspace in order to delete the text in the form then they were simply thrown back to the previous webpage they had visited. This feature was put to its end with the arrival of Google Chrome version 52.

A good thought from Google

At that point of time this feature was seen a major ‘low point’ in the Chrome experience. One of the Google employee even stated that removing that feature brought a major change in the people habit which is a good thing but given the fact the data loss is major issue in today’s time the idea of dropping that feature is well conceived.

Extension to get back to old habits

However people who loved that feature which allowed them to get back without taking the pointer to the back arrow does have some good news. A new Google Chrome extension has come into the play which allows users re-enable this extinct feature on their feature with ease and grace. From now users will get the same old pleasure of hitting the backspace key to back to the previous webpage with this simple browser add-on.

Google is behind the Chrome extension

If you are thinking that some smart user has made this extension in order to bring back the feature to millions of users. Then you will be surprise to know that it is Google who had rolled out the free Chrome extension just week ago on the WebStore. Users are simply required to download the add-on, install it and they are set to visit previous webpages with the stroke of the backspace. Google has titled this extension as ‘Go back With Backspace’ which can be easily found in the Chrome Store.

After installing the extension hitting upon the backspace on the keyboard will bring back the previous webpage. In case you are wondering you will lose your data while filling up the forms online then simply click on the extension icon in the Google Chrome and give a tap on the ‘Disable On This Page’. There is plenty more you can tinker around by simply giving a on the small gear icon for more settings options.

Google has spent some serious time with this extension to make it smarter and innovative accessory for online web browsing experience. Now this extension comes with the default functionality of being disabled for java and flash applets as well as PDFs and the common chat tools.
