Physicists Find a New Way Around Quantum Limits
Tuesday, September 23, 2025
As U.S. automakers invest heavily in plant modernization and digital transformation, a powerful yet often overlooked enabler is emerging at the center of smart manufacturing: data center infrastructure.
Modern automotive production lines are no longer just mechanical. They are increasingly software-driven, sensor-enabled and data-intensive. From robotics and machine vision to AI-enabled quality checks, today's factory floor is generating staggering volumes of data, in some cases up to 5 petabytes (equivalent to 5 million gigabytes) per week. Processing this data quickly and reliably is critical. The difference between milliseconds and minutes in data latency can determine whether operations continue smoothly or grind to a halt due to downtime or production delays.
At the same time, manufacturers are introducing new technologies ranging from smart factories to digital health initiatives to video analytics, all of which require a different type of computing support. Customers and employees alike now expect real-time, on-demand and personalized experiences. They do not tolerate delays or downtime. This creates a dual challenge, and businesses are relying on edge technology to reduce latency, support interactive experiences such as artificial intelligence and virtual reality, protect data stored in remote locations and better monitor sites that lack on-site IT resources.
When we look at what is happening in the market, several pain points are driving businesses toward edge adoption: the need for ultra-low latency, autonomy, privacy and security, adequate bandwidth and interactivity.
This is where micro data centers are playing a transformative role in reshaping automotive manufacturing environments.
Bringing compute power to the factory floor
Traditional data centers, often located hundreds of miles away, are not built to meet the real-time data processing demands of smart manufacturing. The latency involved in transmitting data to remote facilities for processing can be too slow for high-speed industrial operations. Especially in environments with robotics or automated quality assurance, any delay can lead to inefficiencies, safety issues or quality defects.
Micro data centers offer a solution. These compact, self-contained systems integrate compute, storage, networking and cooling capabilities into a single enclosure. They can be deployed directly on or near the production line, providing the high-speed, low-latency data processing that modern factories require. Unlike the custom-built server rooms of the past, today’s micro data centers are modular, scalable and designed for fast deployment with minimal disruption.

Black phosphorus nanoribbons (BPNRs), thin and narrow ribbon-like strips of black phosphorus, are known to exhibit highly advantageous electronic properties, including a tunable bandgap. This essentially means that the energy difference between the region where electrons are bound together (i.e., valence band) and that where electrons move freely (i.e., conduction band) can be easily controlled by adjusting the width of the nanoribbons.
A tunable bandgap is essential for the development of transistors, the components that control the flow of electrical current through electronic devices.
While several past studies have highlighted the promise of BPNRs for the development of electronics, strategies that could enable their reliable fabrication on a large scale are still lacking.
Researchers at Shanghai Jiao Tong University and other institutes recently introduced a new scalable strategy for the realization of high-quality BPNRs that are consistent in size, have well-defined edges and exhibit minimal defects.
Their proposed approach, outlined in a paper published in Nature Materials, relies on a technique designed to peel apart layered materials leveraging ultrasonic sound waves in liquids.
"Our research group has long been devoted to identifying ideal channel materials to enable high-performance field-effect transistors with reduced size and power consumption," Professor Changxin Chen, who led the research, told Phys.org.
"BPNRs offer advantages as channel materials over other candidates such as carbon nanotubes, graphene nanoribbons and two-dimensional (2D) black phosphorus (BP). For example, BPNRs are entirely semiconducting, unlike carbon nanotubes, which can be semiconducting or metallic.
"Additionally, BPNRs exhibit a superior trade-off between mobility and bandgap than graphene nanoribbons. BPNRs also avoid the need to prepare large-area, few-layer 2D BP, providing sizable and widely tunable bandgaps."
For some time, Chen and his colleagues have been trying to devise a scalable strategy to realize high-quality and narrow BPNRs that have smooth edges and well-defined orientations. The fabrication strategy introduced in their recent paper is based on a newly introduced sonochemical exfoliation technique.
"We first used a short-way transport reaction to synthesize bulk BP crystals with a slightly enlarged lattice parameter along the armchair direction," explained Chen.
"This stress allows the crystal to unzip preferentially along the crystal plane perpendicular to the armchair direction rather than other planes. Then, we applied suitable ultrasonic conditions to unzip bulk BP crystals, thereby yielding one-dimensional (1D) high-quality BPNRs."
With their newly devised strategy, the researchers created nanoribbons with a width centered at 32 nm that can be as narrow as 1.5 nm; the narrowest among the BPNRs reported to date. Remarkably, their fabrication method exhibited a yield of up to 95%.
Moreover, the narrow width and zigzag edges of the resulting BPNRs gave rise to a large bandgap, while their nearly atomically smooth edges suppressed carrier scattering and led to high mobility.
"We achieved high-quality, narrow BPNRs with nearly atomically smooth edges and well-defined edge orientation at high yield through the sonochemical exfoliation of the synthesized bulk BP crystals with a slightly enlarged lattice parameter along the armchair direction," said Chen.

Atlantic ocean currents that respond to climate change are hurtling toward a tipping point that could cause severe impacts before the end of this century, a new study finds.
The currents are those that form the Atlantic Meridional Overturning Circulation (AMOC), which loops around the Atlantic Ocean like a giant conveyor belt, bringing heat to the Northern Hemisphere before traveling south again along the seabed. Depending on how much carbon humans emit in the next few decades, the AMOC could reach a tipping point and start to collapse as early as 2055, with dramatic consequences for several regions, researchers found.
This scary prediction, based on a scenario where carbon emissions double between now and 2050, is considered unlikely — but the outcome of a much more likely scenario where emissions hover around current levels for the next 25 years isn't much better, according to the study. Even if we keep global warming this century to 4.8 degrees Fahrenheit (2.7 degrees Celsius) above preindustrial levels — a "middle of the road" scenario, according to the latest U.N. climate report — the AMOC will start to collapse in 2063, the results suggest.
