New technology will speed up smartphone charging by 2,5 times

13.09.2015

Qualcomm, the world's largest smartphone chip manufacturer, has unveiled its next-generation Quick Charge technology, Quick Charge 3.0. Compared to Quick Charge 2.0, it allows you to charge your smartphone about a third faster, while the heat generated during charging is reduced by 45%. The technology was first introduced in early 2013.

Quick Charge 3.0 allows you to charge your smartphone four times faster than devices that do not support Quick Charge and other similar technologies.

Quick Charge 3.0 is capable of charging a smartphone battery up to 80% in 35 minutes, while for smartphones without Quick Charge technology, this time is an average of 1,5 hours.

The technology dynamically changes the voltage at the battery contacts so that maximum current flows through it at any time. Approximately the same technology was described in the invention of the start-up Qnovo from California in August 2014. Its authors claimed a fourfold increase in the speed of charging the battery without increasing its degradation.

To realize the potential of the technology, it is necessary that it be supported by both the mobile device itself and its charger. The technology may be present in the device as a separate integrated circuit or as part of an integrated circuit responsible for powering processors. If a smartphone equipped with Quick Charge is connected with a USB cable to a charger that does not have Quick Charge, there will be no effect.

Quick Charge 3.0 will be available as an option on Qualcomm Snapdragon processors, including the Snapdragon 820, 620, 618, 617 and 430. The first smartphones to market with Quick Charge 3.0 will be available in 2016, Qualcomm says.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Technology at the tip of a golden hair 23.10.2006

Scientists from the USA figured out how to add a single molecule of a substance to the reactor, and at a strictly defined moment.

"Chemists have known for a long time that it is technically possible to control the release of individual molecules of drugs or reagents, but no one has tried to implement this idea. We have brought it to the end," says Professor Peter Searson from Johns Hopkins University. He and his colleagues specialize in growing nanowires from various metals using photolithography methods.

In this case, two pure gold electrode wires were needed. A long hydrocarbon molecule was attached to one of them using a gold-sulfur bond. A biomolecule was attached to the other end of the molecule, which needed to be introduced into the reactor at the right time.

When this moment came, a short current pulse was passed through the electrodes, the bond between gold and sulfur was broken and the molecule set off to float freely. After that, you can attach a new molecule to the electrode and repeat everything from the beginning.

"Our system is quite suitable for implantable chips, which ensure the timely release of drugs into the human body," says Professor Searson. "It will also help to carry out chemical reactions with extremely small amounts of a substance."
