One of the problems affecting electronic equipment is the accumulation of thermal energy. Internal heat concentrates in critical areas that can suffer irreversible damage. Therefore, a group of engineers at the University of Houston is working on a thermal diode capable of redirecting that heat in one direction to prevent it from concentrating in the battery core.

Professor Bo Zhao leads the research group in what is called “thermal rectification,” and promises to usher in a new era in internal temperature management. In their work, they have used “semiconductor materials under a magnetic field, which alters the way thermal radiation propagates at a microscopic level.”

Unlike an electrical diode, which only allows current to flow in one direction, the thermal diode seeks to push heat away from critical areas and prevent it from returning. “In theory, this would allow for more stable temperatures even under demanding conditions, without the need for complex active cooling systems.”

The device is still in the simulation phase. However, it is one of the most anticipated solutions not only for mobile phone users, but also in industrial sectors such as electric vehicles and artificial intelligence server networks.

Apple recognizes that the new iPhone 15 and 15 Pro are experiencing overheating beyond what is considered normal in the first days of use, which it identifies with a bug in iOS 17, which is why it has announced that it is preparing the patches to do so. they will correct.

The first days of using a new mobile device involve not only starting it for the first time but also reconfiguring and downloading backup copies of the services most commonly used by the user.

This configuration of the new smartphone can cause the device to overheat during the first days, due to having a lot of activity in the background, as Apple itself explains to Forbes. But after that initial set-up process, it is not so normal.

“We also found a bug in iOS 17 that is affecting some users and will be fixed in a software update,” he confirms to this medium. And he adds that there is another problem “that has to do with some recent updates to third-party applications that cause them to overload the system.”

Therefore, he states that they are “working with these application developers on fixes that are in the process of being implemented.”

Although more has been said about the overheating problems of the iPhone 15 Pro series, these also affect the iPhone 15 series. Both went on sale on September 22.

In its first week on the market, users who managed to buy one of these smartphones noticed that it became excessively hot, especially during battery charging and with prolonged but not intensive use.

Early speculation suggested that this problem could be due to the A17 Pro processor, although Apple expert analyst Ming-Chi Kuo pointed to the thermal system design as the cause of the problem, due to “concessions made to achieve lighter weight”. Apple has finally linked it to a bug in the operating system, iOS 17.

US authorities are investigating Ford’s response to a recall of 48,924 units of the Mustang Mach-E electric vehicle after receiving several complaints that the problem has not been fixed.

The problem affects the vehicle’s battery contact, an electromagnetic component that functions as a switch for high-power electrical circuits, which can overheat.

Overheating of this key battery component can cause electric vehicles to suddenly and completely lose power while on the road.

Ford detected the defect in 2022 and issued a recall in June of that year to fix the problem with a software update that lowers the voltage if contactor temperatures rise.

The company also later replaced a battery component.

But the US National Highway Safety Administration. (NHTSA, for its acronym in English) published on its website on Monday the opening of an investigation into the recall after receiving 12 complaints from owners of the Mustang Mach- E that the problem persists.

The affected vehicles were produced between May 2020 and May 2022 at Ford’s assembly plant in the Mexican town of Cuautitlán.
