The CEO of third-party charger and accessory company Anker has said that phone charging times will fall to as little as 20 minutes thanks to new-generation Gallium nitride (GaN) chargers, which are already being adopted by Apple. The time cited is for a full charge from empty to full.

Steven Yang said that Apple’s decision to exclude chargers from iPhone boxes has been extremely good news for companies like his …

Yang is interviewed by The Verge’s Nilay Patel. The interview focuses mostly on the company itself, but there are some Apple-related elements.

Scientists at Oak Ridge National Laboratory (ORNL) have developed a scalable, low-cost electrochemical pulse method to improve the contact between layers of materials in solid-state batteries, resolving one of the big challenges in the commercial development of safe, long-lived energy storage systems. The new technology could pave the way for electric vehicles and smartphones that work much longer with each charge.

One of the challenges in manufacturing solid-state batteries is the difficulty of getting materials to properly join and remain stable during repeated cycles of charging and discharging. This leads to instability in the joints and causes the formation of voids, something known as contact impedance. Applying high pressures is one way to solve this problem, but that process can lead to shorting and would need to be re-applied periodically to extend the battery’s life using an expensive aftermarket application.

ORNL scientists have found that they could eliminate these voids by applying a short, high-voltage electrochemical pulse when joining layers of lithium metal anode material with a solid electrolyte material. These pulses see a current surrounding the lithium metal-encased voids and cause them to dissipate, leading to increased contact at the interface of the materials while resulting in no detrimental effects.

Micro-electro-mechanical devices (MEMS) are based on the integration of mechanical and electrical components on a micrometer scale. We all use them continuously in our everyday life: For example, in our mobile phones there are at least a dozen MEMS that regulate different activities ranging from motion, position, and inclination monitoring of the phone; active filters for the different transmission bands, and the microphone itself.

Even more interesting is the extreme nanoscale miniaturization of these devices (NEMS), because it offers the possibility of creating inertial, mass and with such sensitivity that they can interact with single .

However, the diffusion of NEMS sensors is still limited by the high manufacturing cost of traditional silicon-based technologies. Conversely, new technologies such as 3D printing have shown that similar structures can be created at low cost and with interesting intrinsic functionalities, but to date the performance as mass sensors are poor.

The 7,700 square foot store offers baked goods sourced locally, fresh seasonal produce, meat, seafood and ready-made meals, as well as beer, wine and spirits.

There are no cashiers. To make purchases, shoppers need an Amazon account and the free Amazon Go app from the Apple App Store, Google Play or Amazon Appstore, which they can download onto a recent-generation iPhone or Android phone. They swipe a QR code from the app to enter the store.

Engineers have successfully transferred digitally encoded information wirelessly using nuclear radiation instead of conventional technology.

Radio waves and mobile phone signals relies on for communication but in a new development, engineers from Lancaster University in the UK, working with the Jožef Stefan Institute in Slovenia, transferred digitally encoded information using “fast neutrons” instead.

The researchers measured the spontaneous emission of fast neutrons from californium-252, a radioactive isotope produced in nuclear reactors.

Cracked phone screens could become a thing of the past thanks to breakthrough research conducted at The University of Queensland.

The global team of researchers, led by UQ’s Dr Jingwei Hou, Professor Lianzhou Wang and Professor Vicki Chen, have unlocked the technology to produce next-generation composite glass for lighting LEDs and smartphone, television and computer screens.

The findings will enable the manufacture of glass screens that are not only unbreakable but also deliver crystal clear image quality.

The equivalent of cheap 100-inch binoculars will soon be possible. This memo is a quick update on seven rapidly converging technologies that augur well for astronomy enthusiasts of the near future. All these technologies already exist in either fully developed or nascent form, and all are being rapidly improved due to the gigantic global cell phone market and the retinal projection market that will soon replace it. Listed here are the multiple technologies, after which they are brought together into a single system.

1) Tracking.
2) Single-photon image sensing.
3) Large effective exit pupils via large sensors.
4) Long exposure non-photographic function.
5) Flat optics (metamaterials)
6) Off-axis function of flat optics.
7) Retinal projection.

1) TRACKING: this is already being widely used in so-called “go-to” telescopes, where the instrument will find any object and track it, so Earth’s rotation does not take the object viewed out of the field of vision. The viewer doesn’t have to find the object and doesn’t have to set up the clock drive to track it. Tracking is also partly used in image stabilization software for cameras and smart phones, to prevent motion blurring of images.

2) SINGLE-PHOTON IMAGE SENSORS, whether of the single-photon avalanching diode type, or the type developed by Dr. Fossum, will allow passive imaging in nearly totally dark environments, without the use of IR or other illumination. This new type of image sensor will replace the monochromatic analogue “night-vision” devices, allowing color imaging at higher resolution than they can produce. Unlike these current devices, such sensors will not be destroyed by being exposed to normal or high lighting. Effectively, these sensors increase the effective light-gathering power of a telescope by at least an order of magnitude, allowing small telescopes to see what observatory telescopes see now.

Today at AWE 2,021 Qualcomm announced Snapdragon Spaces XR Developer Platform, a head-worn AR software suite the company is using to kickstart a broader move towards smartphone-tethered AR glasses.

Qualcomm says its Snapdragon Spaces XR Developer Platform offers a host of machine perception functions that are ideal for smartphone-tethered AR glasses. The software tool kit focuses on performance and low power, and provides the sort of environmental and human interaction stuff it hopes will give AR developers a good starting point.

Intel senior vice president Keyvan Esfarjani and Intel CEO Pat Gelsinger at the groundbreaking of two new chip fabrication plants in Chandler, Arizona, on Friday, Sept. 24 2021.

Intel Corporation.

The world’s smallest and most-efficient chips are usually referred to as 5 nanometer, a nomenclature that once referred to the width of transistors on the chip. They power cutting-edge data processing and the latest generation of Apple iPhones. TSMC and Samsung make all of these 5-nanometer chips at fabs in Asia.

The concept and technology behind Neuralink are so far ahead of what we’ve grown accustomed to that it might as well be magic. Make no mistake Neuralink is happening and it’ll be here sooner than you think…

I remember the first time I heard about Neuralink. I thought it was a joke or something far off in the future. Then I heard Elon Musk was behind it and immediately knew that this bonkers technology would be with us a lot sooner than any of us imagined.

The concept of Neuralink is simple: you have a chip implanted in your brain and with this chip, you can control things – computer games, applications, your phone, beam thoughts to other Neuralink users. Elon has even demoed the tech working inside a monkey’s head.
