Abstract Currently there are four major pharmaceutical companies who manufacture a SARS-CoV-2 now called SARS-CoV-19 vaccine. These manufactures and their vaccine are Pfizer--BioNTech mRNA Vaccine, the Moderna-Lonza mRNA-1273 Vaccine, the Serum Institute Oxford Astrazeneca Vaccine and the Janssen COVID -19 Vaccine, manufactured by Janssen Biotech Inc., a Janssen Pharmaceutical Company of Johnson & Johnson, a recombinant, replication-incompetent adenovirus type 26 expressing the SARS-CoV-2 spike protein. The intended purpose of these vaccines are to provide immunity from the so-called infectious novel coronavirus or SARS-CoV - 2 virus now called the SARS-CoV - 19. These four pharmaceutical companies have not provided complete...

Most next generation wireless communication technologies require integrated radiofrequency devices that can operate at frequencies greater than 90 GHz. Two of the semiconductors most widely used to fabricate radiofrequency devices are silicon complementary metal-oxide-semiconductor (CMOS) field-effect transistors (FETs) and transistors based on III-V compound semiconductors, particularly GaAs. Both these semiconductor RF technologies, however, are unable to simultaneously achieve high operating frequencies and be easy to integrate within wireless communication technologies. A promising candidate for the development of high-speed FETs (up to terahertz frequencies) are semiconducting single-wall carbon nanotubes (CNTs), due to their favorable electronic and physical properties. Remarkably, the material...

Researchers in The University of Texas at El Paso's Department of Chemistry and Biochemistry have developed a nanohybrid vehicle that can be used to optimally deliver drugs into the human body. The research was published in April 2020 in ACS Applied Materials & Interfaces. Leading the study are Mahesh Narayan, Ph.D., professor, and Sreeprasad Sreenivasan, Ph.D., assistant professor, both from the Department of Chemistry and Biochemistry and the Border Biomedical Research Center (BBRC) in UTEP's College of Science.

Dr. Long Que, assistant professor of electrical engineering at Louisiana Tech University, has reported success in designing and fabricating a device that allows microscale electronic devices to harvest their own wasted energy. The work was described in a paper published in the September edition of Applied Physics Letters, co-authored by students Pushparaj Pathak, Tianhua Zhang, Yuan He, and Shashi Yadav. Developed at Louisiana Tech and described in the paper, this technology uses a cantilever made out of piezoelectric material -- material capable of converting distortions to itself into electrical energy -- and is coated with a carbon nanotube film on...

Most people go to great lengths to keep others from knowing what's going on inside their pants. But skivvies that relay data about the wearer could benefit some people--say soldiers. Yes, we're talking about tighty whities that talk.

Please pardon the vanity ... just wanted to ask a question for a person who got an iPod Nano for Christmas. She can't use her iPod with her iTunes since (apparently) the newer iPods need to use SP3 (XP is her OS). And she can't update Windows to SP3 for the following reason: she bought the computer from a local PC discount store, which has long since gone out of business, and about 3-6 months ago started getting a message that her Windows is not legit (pop-up in the lower-right corner of the screen). She said Microsoft wants $149.99 to...

US and French scientists say the term 'nanoparticle' needs to be redefined to provide a focus for environmental, health and safety studies, and future regulation. According to the researchers, nanomaterials should be categorised based on novel properties that are related to their small size - not, crucially, their size alone.In most countries, few or no specific regulations exist to govern the safe use of nanoparticles, despite their wide use in cosmetics, sun screens and some drug products. Until a decision can be reached on what exactly constitutes a nanoparticle, however, there can be no clear path forward. Although traditionally thought...

MUMBAI (AFP) – The world's cheapest car, the Tata Nano, hit the streets on Friday, as the first customer got the keys to a vehicle that its makers hope will transform travel for millions of Indians. Ashok Raghunath Vichare took delivery of a lunar silver Nano LX model, one of three cars handed over in person by Tata Motors boss Ratan Tata at a city dealership. The 59-year-old customs official from Mumbai said only that he was "very happy" to have got his hands on the car, as he was mobbed by cameras and press photographers. His family, who accompanied...

THE world's cheapest car, the Tata Nano, hit the streets today. The first customer was handed the keys to the vehicle its makers hope will transform travel for millions of Indians. The head of Tata Motors, Ratan Tata, delivered the car in person at a central Mumbai dealership. No details were immediately available about the recipient or the type of Nano being delivered. But analysts said the delivery was a positive step. If follows a land dispute which forced the company to produce the cars in eastern India, delaying its production. "I think it's very significant," the associate editor of...

Is Apple (AAPL) planning to include video cameras in the next versions of the iPod Touch and iPod Nano? TechCrunch’s Michael Arrington floated that theory this morning, asserting that according to “one of our sources in Asia,” Apple has placed an order for “a massive number of camera modules” of the type used in the iPhone 3GS. He says that judging by the size of the order, the cameras can only be for one thing: iPods. The post asserts that the order is so large that camera will be added to the Nano as well as the Touch.

The ultra-budget Tata Nano is being hailed by many as the biggest leap forward since the Model T Ford. So, if they're right, it's more important than the Beetle. More important than the Mini. More important than man's conquest of the moon. And amazingly, more important too than the invention of Sky+. I don't think they are right though. Because the only thing that makes it stand out is the low, low price. Brilliant. But I could make a cheap car if I built it in a factory made from wattle and mud, paid the workers in rice and motivated...

India has made a big splash over the last few days with the announcement by Tata Motors of its new mini-car, the Tata. Even though the car's release was originally scheduled for last year, everyone is still very excited. Finally, an affordable ($2,000 US) car for the masses! (A $60 down payment is all it takes, I have heard.) There are a number of implications of this situation, and reactions from different sides. Let's take a look at a few of them. First, there is the collective *gasp* from the "peak oil" crowd, followed by hysterical Oh Noes. One Australian...

Melbourne: An Australian motoring expert has slammed the world's least expensive car Nano, which was launched in Mumbai Monday, claiming it would increase global pollution and push up fuel prices. "When India gets to the level of car ownership that we enjoy in the West, which is about 700 cars for every 1,000 people, it could double the number of cars on earth, presently 900 million, to 1.8 billion," Wheels magazine's features editor John Cadogan told ABC Radio. "That will have profound impact on carbon dioxide production, greenhouse (gases), the environment and health generally," Cadogan added. However, despite slamming Nano...

DailyTech previously covered the announcement of Tata Motor's Nano car, the world's cheapest car. Despite protests and delays, that car was finally released at a mega-event in Mumbai, India. The car is set to rock developing markets like China and India thanks to an ultra-low price of 100,000 rupees ($2,000 USD). The car is a small 4-door sedan, designed to seat five 6-foot passengers. It weighs a mere 600 kg unladen thanks to its lightweight steel frame. It is powered by a 2-cylinder 624cc, 33 BHP engine -- the kind you would normally find in a motorcycle or scooter. Still,...

Multimedia   Zhong Lin Wang describes his work to power the nanoworld. Nanoscale sensors are exquisitely sensitive, very frugal with power, and, of course, tiny. They could be useful in detecting molecular signs of disease in the blood, minute amounts of poisonous gases in the air, and trace contaminants in food. But the batteries and integrated circuits necessary to drive these devices make them difficult to fully miniaturize. The goal of Zhong Lin Wang, a materials scientist at Georgia Tech, is to bring power to the nano world with minuscule generators that take advantage of piezoelectricity. If he succeeds,...

Widespread use of nanoscale silver will challenge regulatory agencies to balance important potential benefits against the possibility of significant environmental risk, highlighting the need to identify research priorities concerning this emerging technology, according to a new report released today by the Project on Emerging Nanotechnologies (PEN).

When it comes to the world of the very, very small — nanotechnology — Americans have a big problem: Nano and its capacity to alter the fundamentals of nature, it seems, are failing the moral litmus test of religion. In a report published today (Dec. 7) in the journal Nature Nanotechnology, survey results from the United States and Europe reveal a sharp contrast in the perception that nanotechnology is morally acceptable. Those views, according to the report, correlate directly with aggregate levels of religious views in each country surveyed. In the United States and a few European countries where religion...

With a $1.6M grant from the U.S. Office of Naval Research (ONR), UC San Diego NanoEngineering professor Joseph Wang will lead a project to create a "field hospital on a chip" that soldiers can wear on the battlefield. The automated sense-and-treat system will continuously monitor a soldier's sweat, tears or blood for biomarkers that signal common battlefield injuries such as trauma, shock, brain injury or fatigue. Once the system detects a battlefield injury, it will automatically administer the proper medication, thus beginning the treatment well before the soldier has reached a field hospital. "Since the majority of battlefield deaths occur...

Geckos have long inspired scientists and super-hero fans alike with their ability to scamper up vertical walls and cling to ceilings with a single toe. In recent years, people have attempted to create materials that match those spectacular abilities, in the hope of creating new advanced adhesives, or even car braking systems.Now US chemists claim to have made one based on nanotubes that it is 10 times stickier than some gecko feet. Even more impressively, like a real gecko foot, it can also be easily unstuck with a tug in the right direction.Gecko's superhero toes are covered in microscopic hairs,...
