Europe will soon produce a strategically vital component in the modern global economy as US semiconductor giant Intel chooses the site for a new cutting-edge chip factory.

Recent problems in global supply chains have highlighted the fundamental importance of semiconductors, which are used in a growing number of products including cars, TVs and smartphones.

Keen demand and the closure of semiconductor plants, particularly in Asia, due to pandemic disruptions led to a global chip shortage and forced car manufacturers such as Ford, Nissan and Volkswagen to scale back production.

A Rice University-led study is forcing physicists to rethink superconductivity in uranium ditelluride, an A-list material in the worldwide race to create fault-tolerant quantum computers.

Uranium ditelluride crystals are believed to host a rare “spin-triplet” form of superconductivity, but puzzling experimental results published this week in Nature have upended the leading explanation of how the could arise in the material. Neutron-scattering experiments by physicists from Rice, Oak Ridge National Laboratory, the University of California, San Diego and the National High Magnetic Field Laboratory at Florida State University revealed telltale signs of antiferromagnetic spin fluctuations that were coupled to superconductivity in uranium ditelluride.

Spin-triplet superconductivity has not been observed in a solid-state material, but physicists have long suspected it arises from an ordered state that is ferromagnetic. The race to find spin-triplet materials has heated up in recent years due to their potential for hosting elusive quasiparticles called Majorana fermions that could be used to make error-free quantum computers.

Tsinghua Unigroup Co, one of China’s biggest semiconductor giants and a key server supplier to the Chinese government entities is burdened with debt default.

The Chinese Communist Party (CCP) yet again finds itself in the middle of a battle with the private sector and tech entrepreneurs. This time over the all-important semiconductors. Tsinghua Unigroup Co., one of China’s biggest semiconductor giants and a key server supplier to the Chinese government entities, is burdened with debt defaults and undergoing rescue process.

Without naming the CCP, Zhao is promising to stand up to Communist Party leadership. In Xi’s enterprise-hating China, a private entity doesn’t simply rise out of nowhere and take over a leading semiconductor giant. And if any entity can dare to do that, it must be having the informal backing of the Communist Party.

Quantum effects in superconductors could give semiconductor technology a new twist. Researchers at the Paul Scherrer Institute PSI and Cornell University in New York State have identified a composite material that could integrate quantum devices into semiconductor technology, making electronic components significantly more powerful. They publish their findings today in the journal Science Advances.

Our current electronic infrastructure is based primarily on semiconductors. This class of materials emerged around the middle of the 20th century and has been improving ever since. Currently, the most important challenges in semiconductor electronics include further improvements that would increase the bandwidth of data transmission, energy efficiency and information security. Exploiting is likely to be a breakthrough.

Quantum effects that can occur in superconducting materials are particularly worthy of consideration. Superconductors are materials in which the electrical resistance disappears when they are cooled below a certain temperature. The fact that quantum effects in superconductors can be utilized has already been demonstrated in first quantum computers.

The new fiber battery is manufactured using novel battery gels and a standard fiber-drawing system. In a press release issued by MIT, MIT postdoc Tural Khudiyev noted that previous attempts to make batteries in fiber form were structured with key materials on the outside of the fiber. In the latest development, his system embeds the lithium and other materials inside the fiber, with a protective outside coating, creating a stable and waterproof version. He said it demonstrates that it’s possible to make a fiber battery that can be up to a kilometer long and highly durable, having many practical applications. As Khudiyev puts it, “there’s no obvious upper limit to the length. We could definitely do a kilometer-scale length.”

The 140-meter fiber produced can charge smartwatches or phones, with an energy storage capacity of 123 milliamp-hours.

“The beauty of our approach is that we can embed multiple devices in an individual fiber,” said former MIT postdoc Jung Tae Lee. The team had exhibited the integration of LED and Li-ion batteries in a single fiber, and Lee believes that more than three or four devices can be combined in such a small space in the future. “When we integrate these fibers containing multi-devices, the aggregate will advance the reaggregate of a compact fabric computer,” he added.
