Engineering quantum entanglement at the nanoscale

Posted by in categories: engineering, nanotechnology, particle physics, quantum physics

Physicists have spent more than a century measuring and making sense of the strange ways that photons, electrons, and other subatomic particles interact at extremely small scales. Engineers have spent decades figuring out how to take advantage of these phenomena to create new technologies.

In one such phenomenon, called , pairs of photons become interconnected in such a way that the state of one instantly changes to match the state of its paired photon, no matter how far apart they are.

Nearly 80 years ago, Albert Einstein referred to this phenomenon as “spooky action at a distance.” Today, entanglement is the subject of research programs across the world—and it’s becoming a favored way to implement the most fundamental form of quantum information, the qubit.

Nuclear fusion could be the clean energy of the future — but these ‘tough’ challenges stand in the way

Posted by in categories: engineering, nuclear energy

Even once researchers can reliably get more power out of a fusion reaction than they put in, they’ll still need to overcome engineering challenges to scale up fusion energy.

Fully recyclable carbon nanotube fibers have far-reaching implications for manufacturing across sectors

Posted by in categories: chemistry, economics, energy, engineering, nanotechnology, sustainability

In a significant step toward creating a sustainable and circular economy, Rice University researchers have published a study in the journal Carbon demonstrating that carbon nanotube (CNT) fibers can be fully recycled without any loss in their structure or properties. This discovery positions CNT fibers as a sustainable alternative to traditional materials like metals, polymers and the much larger carbon fibers, which are notoriously difficult to recycle.

“Recycling has long been a challenge in the materials industry—metals recycling is often inefficient and energy-intensive, polymers tend to lose their properties after reprocessing and carbon fibers cannot be recycled at all, only downcycled by chopping them up into short pieces,” said corresponding author Matteo Pasquali, director of Rice’s Carbon Hub and the A.J. Hartsook Professor of Chemical and Biomolecular Engineering, Materials Science and NanoEngineering and Chemistry.

Scientists Crack the Code of Titanium’s Strength and Flexibility

Posted by in categories: biotech/medical, chemistry, cyborgs, engineering

A research team from Yokohama National University has developed a novel approach to investigate how the orientation and behavior of electrons in titanium affect its physical properties. Their findings, published in Communications Physics on December 18, 2024, offer valuable insights that could lead to the creation of more advanced and efficient titanium alloys.

Titanium is highly prized for its exceptional resistance to chemical corrosion, lightweight nature, and impressive strength-to-weight ratio. Its biocompatibility makes it an ideal material for medical applications such as implants, prosthetics, and artificial bones, while its strength and durability make it indispensable in aerospace engineering and precision manufacturing.

How Scientists Are Using Atomic Precision to Supercharge Chemistry

Posted by in categories: chemistry, engineering, nanotechnology, particle physics

Bimetallic particles, made from a combination of a noble metal and a base metal, have unique catalytic properties that make them highly effective for selective heterogeneous hydrogenation reactions. These properties arise from their distinctive geometric and electronic structures. For hydrogenation to be both effective and selective, it requires specific interactions at the molecular level, where the active atoms on the catalyst precisely target the functional group in the substrate for transformation.

Nanoscale Engineering and Electronic Structure Tuning

Scaling these particles down to nanoscale atomic clusters or single-atom alloys further enhances their catalytic performance. This reduction in size increases surface dispersion and optimizes the use of noble metal atoms. Additionally, these nanoscale changes alter the electronic structure of the active sites, which can significantly influence the activity and selectivity of the reaction. By carefully adjusting the bonding between noble metal single atoms and the base metal host, researchers can create flexible environments that fine-tune the electronic properties needed to activate specific functional groups. Despite these advances, achieving atomically precise fabrication of such active sites remains a significant challenge.

Flexible electronics integrated with paper-thin structure for use in space

Posted by in categories: engineering, satellites

Innovative integration of flexible electronics with a lightweight, self-deployable boom offers multifunctionality for space applications. This ultrathin composite structure, designed to withstand harsh space conditions, enhances satellite capabilities. The Virginia Tech CubeSat, featuring this technology, is set for a 2025 launch.


Being lightweight is essential for space structures, particularly for tools used on already small, lightweight satellites. The ability to perform multiple functions is a bonus. To address these characteristics in a new way, researchers at the University of Illinois Urbana-Champaign successfully integrated flexible electronics with a three-ply, self-deployable boom that weighs only about 20 grams.

The study, “Multifunctional bistable ultrathin composite booms with ,” by Yao Yao and Xin Ning from Illinois, Juan Fernandez from NASA Langley Research Center and Sven Bilén at Penn State, is published in Extreme Mechanics Letters.

Researchers image magnetic skyrmions at room temperature for the first time

Posted by in categories: engineering, particle physics

An international research team, working with cutting-edge technology at the University of Nebraska–Lincoln, has made a discovery that may dramatically expand the materials used in next-generation, energy-efficient memory and logic devices.

The team, which includes Nebraska’s Abdelghani Laraoui, assistant professor of mechanical and materials engineering, successfully demonstrated for the first time the imaging of magnetic skyrmions at room temperature in composition engineered . The team observed the tiny, vortex-like particles in these magnetic materials using a nitrogen-vacancy scanning probe in Laraoui’s lab. The findings are published in ACS Nano.

“This discovery is a huge step forward because, until now, scientists could only observe these skyrmions in bulk chiral magnetic materials at very low temperatures,” Laraoui said. “Being able to study them at room temperature opens up a whole new world of applications and possibilities.”
