The fundamental rotation of micro and nano-objects is crucial for the functionality of micro and nanorobotics, as well as three-dimensional imaging and lab-on-a-chip systems. These optical rotation methods can function fuel-free and remotely, and are therefore better suited for experiments, while current methods require laser beams with designed intensity profiles or objects with sophisticated shapes. These requirements are challenging for simpler optical setups with light-driven rotation of a variety of objects, including biological cells.
In a new report now published in Science Advances, Hongru Ding and a research team in engineering and materials science at the University of Texas at Austin, U.S., developed a universal approach for the out-of-plane rotation of various objects based on an arbitrary low-power laser beam. The scientists positioned the laser source away from the objects to reduce optical damage from direct illumination and combined the rotation mechanism via optothermal coupling with rigorous experiments, coupled to multiscale simulations. The general applicability and biocompatibility of the universal light-driven rotation platform is instrumental for a range of engineering and scientific applications.
Hyundai is offering an early look at its upcoming all-electric sedan, the Ioniq 6. It comes as Bloomberg reports that the company’s EV market share is quietly surging in Europe and the US, causing even Tesla’s Elon Musk to take notice.
Hyundai has revealed an early look at its upcoming all-electric sedan, the Ioniq 6. It draws inspiration from the kind of streamlined car designs that were popular in the 20s and 30s with vehicles like the Stout Scarab.
Do you remember the days in schooling when we attended math classes? The most common question was when we would ever use trigonometric functions or other mumbo-jumbo in real life.
How is it possible for a virtual world to create the exact replica of a person in zeroes and ones? There is not just one technology aiding in creating the fascinating world of Metaverse and IoT is one amongst them.
The current electric vehicle market is entirely dominated by lithium-ion batteries (LIBs). However, due to the limited and unequal distribution of LIB raw materials on earth, there is a continuous effort to design alternate storage devices. Among the alternatives to LIBs, sodium-ion batteries (NIBs) are at the forefront because sodium resources are ubiquitous worldwide and virtually inexhaustible. However, one of the major drawbacks of the NIBs is their low specific charge capacity. Since the specific charge capacity of a cell can be improved by increasing the specific charge capacity of the anode material, there is a constant effort to find suitable anode materials. Recent studies suggested that a cobalt-boride (CoB) anti-MXene material (a newly discovered two-dimensional material) can yield superior specific charge capacities for LIBs than traditional graphite-based anodes.
Back when the Cadillac CT6 was the new hotness for the brand still trying to stand up to its full height, rumors abounded of a new model well above that to challenge the rarified trims among German luxury competition. The most oft-repeated portion of that rumor was that the model would cost well more than $100,000. When Cadillac’s electric turn gathered momentum, we began hearing about a sedan called the Celestiq that would be the pride of the fleet. It doubled the potential starting price of the previous flagship, as recently as this month being touted as costing more than $200,000. A report in the Wall Street Journal suggests that is correct. Citing “people familiar with the matter,” the paper said, “the Celestiq price tag could run well beyond $300,000 depending on added features.”
A straight reading suggests an MSRP somewhere above $200,000 and an options menu with enough pricey choices to cross the $300K tier. In itself, that’s not outrageous. The 2023 BMW i7 can be optioned from a starting price of $120,000 to $155,000. The Porsche Taycan Turbo S can be optioned from $188,000 to $237,000 by checking a few boxes in just five of the potential 31 menu categories. The jumps go logarithmic when one steps up to superluxe models from makers like Aston Martin and Bentley and Rolls-Royce. So throwing $50,000 in options at a car that starts at $275,000 isn’t much of a story.
The story is that we’re talking about Cadillac, and these kinds of numbers would represent huge changes for the brand’s pricing and options. The 2023 Escalade-V doesn’t have a configurator yet, so starting with the $112,500 Escalade ESV Sport Platinum 4WD in four-wheel drive, clicking every mechanical and luxury accessory got us to almost $135,000, representing $23,500 in options. If the WSJ is even close in its assessment, the Celestiq could start around $100,000 more than the $150,000 Escalade-V and then unveil the kind of options menu that’s usually read in a British accent by someone wearing $3,000 shoes.
Elon Musk may be an oddball online, but he helped bring a lot of technology to the world. Happy Birthday Elon Musk! Here’s a Look on the Tech CEO’s Significance in the World.
Elon Musk talked about the advantages of Tesla ads in an interview with Tesla supporters, including the President of Tesla Owners Silicon Valley, the President of My Tesla Adventure, and the Kilowatts founder.
Musk noted that public support for Tesla is appreciated, and the Tesla community’s efforts to shoot down FUD (fear, uncertainty, and doubt) for the company have also been helpful. Musk has opposed the idea of Tesla ads in the past. However, during the interview, he acknowledged that Tesla ads might have some advantages.
“There’s an argument for maybe we should advertise because the traditional media will not run negative pieces about automotive. Because automotive is like one of the biggest—if not the biggest—advertisers in their paper,” Musk said.
😳!!!
Anyone intending to toss the bike up on a car rack or into a truck should note that it isn’t lightweight, tipping the scales at 75 lb (34 kg). You can remove 9 lb (4 kg) of that just by taking the battery off. With a massive motor and large battery, you didn’t expect it to be a featherweight though, did you?
Outfitting the bike with massive 4″ fat tires didn’t do the weight any favors either, though it certainly helps the FT1000MD cover just about any terrain. With that much air volume, the damn thing almost floats.
The differences? The new Mayflower—logically dubbed the Mayflower 400—is a 50-foot-long trimaran (that’s a boat that has one main hull with a smaller hull attached on either side), can go up to 10 knots or 18.5 kilometers an hour, is powered by electric motors that run on solar energy (with diesel as a backup if needed), and required a crew of… zero.
That’s because the ship was navigated by an on-board AI. Like a self-driving car, the ship was tricked out with multiple cameras (6 of them) and sensors (45 of them) to feed the AI information about its surroundings and help it make wise navigation decisions, such as re-routing around spots with bad weather. There’s also onboard radar and GPS, as well as altitude and water-depth detectors.
The ship and its voyage were a collaboration between IBM and a marine research non-profit called ProMare. Engineers trained the Mayflower 400’s “AI Captain” on petabytes of data; according to an IBM overview about the ship, its decisions are based on if/then rules and machine learning models for pattern recognition, but also go beyond these standards. The algorithm “learns from the outcomes of its decisions, makes predictions about the future, manages risks, and refines its knowledge through experience.” It’s also able to integrat e far more inputs in real time than a human is capable of.
