iPhone 12: Renders surface before Apple’s official smartphone reveal

0 Comments

Apple will unwrap the new iPhone in just a few hours during its online event ‘Hi, Speed’ and leaks of what the smartphone could look like have surfaced.

The launch, which is set for 1pm ET, is set to unveil four models of the flagship handset, ranging in price from $699 to $1,099.

Notably smartphone leaker, Evan Blass, released renders of the devices, showing the iPhone 12 mini, iPhone 12, iPhone 12 Pro and iPhone 12 Pro Max.

Although the render are of only the fronts and backs, they do confirm several details that have been rumored about the smartphones.

The images show a new blue color that is set for the higher-end devices, along with a look at the new LIDAR sensor.

Although Apple has yet to reveal details of the iPhone 12, it is speculated that it will cost $799 and be available for pre-order on either October 6 or 7.

The next iPhone has been a big topic this year, as coronavirus lockdowns caused disruptions to Apple’s global supply chain that caused a number of delays for the tech giant.

Last month, Apple had confirmed that iOS users would not see the new device until October – but that time has finally come.

The Apple Store online is down, which means the tech giant is gearing up to launch the new iPhones and add them to the site. 

Rumors have suggested that the biggest upgrade to the iPhone this year will be 5G

Surface waves can help nanostructured devices keep their cool — ScienceDaily

The continuing progress in miniaturization of silicon microelectronic and photonic devices is causing cooling of the device structures to become increasingly challenging. Conventional heat transport in bulk materials is dominated by acoustic phonons, which are quasiparticles that represent the material’s lattice vibrations, similar to the way that photons represent light waves. Unfortunately, this type of cooling is reaching its limits in these tiny structures.

However, surface effects become dominant as the materials in nanostructured devices become thinner, which means that surface waves may provide the thermal transport solution required. Surface phonon-polaritons (SPhPs) — hybrid waves composed of surface electromagnetic waves and optical phonons that propagate along the surfaces of dielectric membranes — have shown particular promise, and a team led by researchers from the Institute of Industrial Science, the University of Tokyo has now demonstrated and verified the thermal conductivity enhancements provided by these waves.

“We generated SPhPs on silicon nitride membranes with various thicknesses and measured the thermal conductivities of these membranes over wide temperature ranges,” says lead author of the study Yunhui Wu. “This allowed us to establish the specific contributions of the SPhPs to the improved thermal conductivity observed in the thinner membranes.”

The team observed that the thermal conductivity of membranes with thicknesses of 50 nm or less actually doubled when the temperature increased from 300 K to 800 K (approximately 27°C to 527°C). In contrast, the conductivity of a 200-nm-thick membrane decreased over the same temperature range because the acoustic phonons still dominated at that thickness.

“Measurements showed that the dielectric function of silicon nitride did not change greatly over the experimental temperature range, which meant that the observed thermal enhancements could be attributed to the action of the SPhPs,” explains the Institute of Industrial Science’s Masahiro Nomura, senior author of the study. “The SPhP

Moon May Harbor Ancient Pieces Of Venus’ Surface

0 Comments

Two Yale University researchers have found a potential shortcut in sampling Venus’ ancient surface. Instead of sending a probe on a costly and extraordinarily challenging Venus sample return mission, they propose simply finding a Venusian meteorite on our own Moon.

There’s never been a bona fide detection of a Venusian meteorite on Earth. For one reason, that’s because in the last several hundred million years at least, Venus’ atmospheric pressures have been so intense that even a catastrophic impactor could not dislodge any Venusian rocks into space. 

But before Venus underwent a runaway greenhouse and morphed into the climatic hellhole it is today, it may have had liquid water oceans as late as 700 million years ago. If so, its atmosphere would have been thin enough for surface rocks to have been dislodged by massive impactors and possibly have found their way to both the Earth and our Moon. 

Due to weathering here on Earth, Venusian meteorites on Earth wouldn’t survive long. But because our Moon has no atmosphere, the authors of a paper accepted by The Planetary Science Journal posit that the Moon may have be the ideal spot to preserve Venus meteorites. 

Lead author Samuel Cabot and co-author Gregory Laughlin investigated the amount of material ejected from Venus when it suffered past impacts from asteroids and comets, and then traced the orbits of the rocks throughout the Solar System. They found that a small (but still significant) fraction of rocks ejected from Venus will be swept up by Earth’s Moon. 

Today, due to Venus’ thick atmosphere, even a catastrophic impactor would not

What tiny surfing robots teach us about surface tension — ScienceDaily

0 Comments

Spend an afternoon by a creek in the woods, and you’re likely to notice water striders — long-legged insects that dimple the surface of the water as they skate across. Or, dip one side of a toothpick in dish detergent before placing it in a bowl of water, and impress your grade schooler as the toothpick gently starts to move itself across the surface.

Both situations illustrate the concepts of surface tension and propulsion velocity. At Michigan Technological University, mechanical engineer Hassan Masoud and PhD student Saeed Jafari Kang have applied the lessons of the water strider and the soapy toothpick to develop an understanding of chemical manipulation of surface tension.

Their vehicle? Tiny surfing robots.

“During the past few decades, there have been many efforts to fabricate miniature robots, especially swimming robots,” said Masoud, an assistant professor in the mechanical engineering-engineering mechanics department. “Much less work has been done on tiny robots capable of surfing at the interface of water and air, what we call liquid interfaces, where very few robots are capable of propelling themselves.”

Beyond the obvious implications for future Lucasfilm droids designed for ocean planets (C-H2O), what are the practical applications of surfing robots?

“Understanding these mechanisms could help us understand colonization of bacteria in a body,” Masoud said. “The surfing robots could be used in biomedical applications for surgery. We are unraveling the potential of these systems.”

Hunting for Answers and the Marangoni Effect

During his doctoral studies and postdoc appointment, Masoud conducted research to understand the hydrodynamics of synthetic microrobots and the mechanisms by which they move through fluid. While helping a colleague with an experiment, Masoud made an observation he couldn’t explain. An aha! moment came shortly thereafter.

“During a conversation with a physicist, it occurred to me that what we had observed
