New research examines corrosion on atomic level
When water vapor meets metal, the resulting corrosion can lead to mechanical problems that harm a machine’s performance. Through a process called passivation, it also can form a thin inert layer that acts as a barrier against further deterioration.
Either way, the exact chemical reaction is not well understood on an atomic level, but that is changing thanks to a technique called environmental transmission electron microscopy (TEM), which allows researchers to directly view molecules interacting on the tiniest possible scale.
Professor Guangwen Zhou—a faculty member at Binghamton University’s Thomas J. Watson College of Engineering and Applied Science—has been probing the secrets of atomic reactions since joining the Department of Mechanical Engineering in 2007. Along with collaborators from the University of Pittsburgh and the Brookhaven National Laboratory, he has studied the structural and functional properties of metals and the process of making “green” steel.
Professor Brings Insight to Cell Therapy with Nanobots
There’s an unfortunate irony in cell therapy that holds it back from its full potential: Regenerating tissues often must be damaged to know if the treatment is working, such as surgically removing tissue to see if rejuvenation is occurring beneath.
The alternative isn’t much better: Patients can choose to wait and see if their health improves, but after weeks of uncertainty, they might find that no healing has taken place without a clear explanation as to why.
Jinhwan Kim, a new assistant professor of biomedical engineering at the University of California, Davis, who holds a joint appointment with the Department of Surgery at UC Davis Health, wants to change all of that. In his research program, he combines nanotechnology and novel bioimaging techniques to provide non-invasive, real-time monitoring of cellular function and health.
Researchers Use Molecular Engineering To Improve Organic Solar Cell Efficiency
Polymer solar cells, known for their light weight and flexibility, are ideal for wearable devices. Yet, their broader use is hindered by the toxic halogenated solvents required in their production. These solvents pose environmental and health risks, limiting the appeal of these solar cells. Alternative solvents, which are less toxic, unfortunately, lack the same solubility, necessitating higher temperatures and prolonged processing times.
This inefficiency further impedes the adoption of polymer solar cells. Developing a method to eliminate the need for halogenated solvents could significantly enhance the efficiency of organic solar cells, making them more suitable for wearable technology.
In a recently published paper, researchers outline how improving molecular interactions between the polymer donors and the small molecule acceptors using side-chain engineering can reduce the need for halogenated processing solvents.
A micro-ring resonator with big potential: Hybrid device significantly improves laser technology
The team at EPFL’s Photonic Systems Laboratory (PHOSL) has developed a chip-scale laser source that enhances the performance of semiconductor lasers while enabling the generation of shorter wavelengths.
This pioneering work, led by Professor Camille Brès and postdoctoral researcher Marco Clementi from EPFL’s School of Engineering represents a significant advance in the field of photonics, with implications for telecommunications, metrology, and other high-precision applications.
The study, published in the journal Light: Science & Applications, reveals how the PHOSL researchers, in collaboration with the Laboratory of Photonics and Quantum Measurements, have successfully integrated semiconductor lasers with silicon nitride photonic circuits containing microresonators. This integration results in a hybrid device that emits highly uniform and precise light in both near-infrared and visible ranges, filling a technological gap that has long challenged the industry.
A superconducting junction made from a single 2D material promises to harness strange new physics
Physicists at RIKEN have developed an electronic device that hosts unusual states of matter, which could one day be useful for quantum computation.
When a material exists as an ultrathin layer—a mere one or a few atoms thick—it has totally different properties from thicker samples of the same material. That’s because confining electrons to a 2D plane gives rise to exotic states. Because of their flat dimensions and their broad compatibility with existing semiconductor technologies, such 2D materials are promising for harnessing new phenomenon in electronic devices.
These states include quantum spin Hall insulators, which conduct electricity along their edges but are electrically insulating in their interiors. Such systems when coupled with superconductivity have been proposed as a route toward engineering topological superconducting states that have potential application in future topological quantum computers.

Road Salts and Environmental Consequences: A Global Perspective
Are humans disrupting the Earth’s salt cycle through deicing roads and other salt activities? This is what a recent study published in Nature Reviews Earth & Environment hopes to address as a team of researchers led by the University of Maryland examine the environmental impact of salting roads as a safety measure from freezing temperatures, resulting in increased levels of salt throughout the environment, including the air, soil, and water, thus disrupting the Earth’s natural salt cycle. While the Earth’s natural salt cycle is a process that occurs over vast periods of geologic time, human activities are increasing this cycle in alarming ways.
Salts being used as deicing agents are common across the United States during the winter, with more than 44 billion pounds of deicing agent used annually. In fact, between 2013–17, road salts accounted for 44 percent of the salt use in the United States, which accounts for 13.9 percent of total dissolved solids that make their way into streams and waterways across the nation.
“This is a slow-moving train wreck,” said Dr. Megan Rippy, who is an assistant professor in civil and environmental engineering at Virginia Tech and a co-author on the study. “It’s playing out so slowly that it’s easy to overlook that our streams, lakes, and drinking water resources are becoming progressively saltier.”
